Nissans Safety
TechnologyDevelopment ConceptBased on the concept of Real World Safety,Nissan is working to create safer automobiles withthe goal of halving the number of automobileaccident fatalities or serious injuries involving itsvehicles by 2015 as compared to 1995. Already,Nissan has made significant progress with oc-cupant protection technologies such as SRS airbagsystems and Zone Body construction, hazard eva-sion technologies such as ABS and VDC, and driv-
ing support technologies such as AFS reflectedin a 27% reduction in fatal and serious injuriesinvolving Nissan vehicles in 2004 compared to1995. However, further work is needed to counteran upward trend in the total number of accidentsand create a safer automobile society.Real World Safety: Nissans concept of analyzing the causes of actual accidents to develop and adopteffective technologies to combat each problem.*ABS: Anti-lock Braking System *VDC: Vehicle Dynamics Control*AFS: Adaptive Front Lighting System

Nissans Approach
to SafetyThe automobile represents a fun and conve-nient form of mobility that can be operatedby an individual. At Nissan, we seek to makevehicles that provide a rich and joyful drivingexperience, while offering outstanding depend-ability and safety to assure peace of mind. Toachieve a safer automobile society, we are notonly building safer vehicles, but also improvingthe environment surrounding cars and their driv-ers through ITS (Intelligent Transport Systems)
applications and enhancing peoples awarenessof safety issues through educational activities.

SAFETY SHIELD
Nissans concept of "the vehicle that helps
protect people."
Various barriers around the vehicle help the driverand passengers avoid dangers from normal driving
conditions through post accident conditions.
Safety TechnologyDevelopment Process
Investigation and verification are essential for tech-
nological innovation. Nissan re-creates accidents
through simulation and experiments based on
analysis of accident data collected from around the
world. In this way, Nissan identifies the issues and
develops new technologies while improving existing
safety technologies. This process is key to the con-
tinuous evolution of safety performance at Nissan.
Nissan noticed that analysis of actual accidents
revealed the primary human factor to be recogni-
tion error. This means that to reduce accidents we
must not stop at developing conventional safety
technology. A further step of technological innova-
tion is also necessary to support the human factors
that help maintain safe driving conditions.
Against this background, Nissan created the origi-
nal approach to safety technology development
called Safety Shield.

SAFETY SHIELDNissans concept of the vehicle that helps protect people.
In the area of safety technology, Nissan pursues innovation as part of its Safety Shield concept,an advanced, proactive approach to safety issues based on the idea that cars should help protect
people. This approach provides various measures to help the driver and passengers better avoid
dangers in ways that are optimized to each of a wide range of circumstances that the vehicle may
be in, from risk has not yet appeared to post-crash.

Safety ActivitiesTechnology Overview
Recognizing that people are the key actors in the activity of driving, Nissan develops technology witha view toward supporting the driver in control of the car. This means developing systems that provide
the driver with appropriate information in a timely fashion and respond to driver inputs according to
the driver's intentions. It also means development of vehicle systems that may intervene to help reduce
injuries and damage in case a crash becomes unavoidable. Based on this Safety Shield approach,
Nissan targets ongoing innovation toward the realization of a safer automobile society.

Helps the driver to maintain comfortable driving
Even when risk has not appeared, Nissan technologies make it easier for the driver to maintain safedriving conditions. Some of these innovations reduce the drivers burden, while others enhance visibilityand awareness of the immediate surroundings at night and when parking, for example.
Distance Control Assist System
Using a radar sensor installed in the front bumper,
this system helps drivers control the distancebetween themselves and the vehicle in front. For
example, if the driver releases or is not pressingthe accelerator pedal, the system automatically
applies the brakes to help control the distancefrom the vehicle in front. Or, if the preceding
vehicle slows down and the system determinesthat braking is required, visual and aural indicators
prompt the driver to take action. The acceleratorpedal also lifts up to assist the driver in switching
to the brakes. These functions alleviate the burdenon the driver, particularly under traffic conditions
that require frequent braking.
Accelerator pedal actuator
Too close to preceding vehicle
If the driver releases the accelerator, the system automaticallyapplies the brakes.*
* Brakes are applied automatically only when the driver is not pressing the accelerator.
Braking is required by driver(when preceding driver slows down, etc.)
Along with an audible warning and an indicator display, the accel-erator pedal rises to assist the driver in switching to the brake pedal.

Safety ActivitiesTechnology Overview
If there is a vehicle in the lane ahead, the system
uses data from a radar sensor installed in the frontbumper to control following distance appropriately
in accordance with the preset cruising speed(about 40 to 100km/h). If there is no vehicle
ahead, the preset cruising speed is maintained.The low-speed following mode operates at speeds
under about 40km/h to maintain an appropriatefollowing distance in congested traffic, thereby
helping reduce the drivers workload. The systemprovides further convenience by switching
automatically between Intelligent Cruise Controlmode and low-speed following mode.

Low-speed following capability
If the sensor detects a vehicle in the lane ahead and the driver
turns on the system while driving between about 10 and 40km/h,
this will maintain a following distance in accordance with vehicle
speed, up to about 40km/h.System operation is suspended when the lane ahead is clear.
If the preceding vehicle slows down, the system slows the car
and, when necessary, an audible warning and visual indica-
tion prompt the driver to perform braking. Below about 5km/h,
system operation is suspended and the audible warning and
visual indication prompt the driver to perform braking on his or
her own.
Maintains inter-vehicle distance
When inter-vehicle distance shortens, the system slows the vehicle and
informs the driver by sight and sound
Automatically switches between Intelligent Cruise Control mode
and low-speed following mode.
When using Intelligent Cruise Control to follow a vehicle, the
low-speed following mode activates automatically i f vehicle
speed drops below about 35km/h.
During low-speed following, if speed rises above about 40km to
keep pace with a preceding vehicle, Intelligent Cruise Control
will take over if the driver has preset a cruise control speed.
When inter-vehicle distance shortens, the system slows the vehicle and
maintains an optimum distance appropriate to speed
When inter-vehicle distance lengthens, the system speeds up the vehicle and
maintains an optimum distance appropriate to speed

Halogen headlamps
Adaptive Front Lighting System (AFS)
Most pedestrian fatalities occur at night, soimproved visibility is vital to help avoid suchaccidents. Nissans AFS automatically swivels theangle of AFS lamps (located in the headlamps)in the direction the vehicle is turning, based onsteering angle and vehicle speed, thereby helpingto reveal obstacles in the vehicle path.
Xenon headlamps
For improved visibility, Xenon headlamps producebright white light that is close to sunlight in color.This powerful yet natural looking illuminationenhances confidence for night driving safety.

Helps the driver to recover from dangerousconditions to safe driving
When a risk appears, warnings and automatic countermeasures help the driver avoid it.
Using a front-mounted camera to detect lane
divider lines, this system warns the driver via
sound and an indicator display when the vehicle
is unintentionally drifting out of its lane. In 2004,
Nissan became the first to adopt Lane Departure
Warning technology in passenger vehicles in
North America.
Operation is suspended if the appropriate turn
signal has been turned on.
Lane Departure Warning
In case of unintentional lane departure, this tech-
nology not only warns the driver via sound and an
indicator display, but also generates a turning force
to help the driver return the vehicle to its lane.

Safety ActivitiesTechnology Overview
4 Wheel Active Steer
This technology controls the steering angle ofeach wheel independently according to conditions.For example, in case of high-speed avoidancemaneuvers, it helps improve stability and respon-siveness, so the driver can better follow the intend-ed path. At slower speeds, it adjusts the steeringgear ratio to make it easier to steer the vehiclewith less effort.
Electronic Brakeforce Distribution (EBD)
An application of anti-lock braking system (ABS)technology, EBD controls rear-wheel brakingbased on detection of loss of traction at the frontand rear wheels when the brakes are applied.By controlling distribution of braking force to thefront and rear wheels according to the passenger
and luggage load, EBD minimizes differences inbraking performance whether the vehicle load islight or heavy.

Anti-lock Braking System (ABS)
ABS electronically controls hydraulic brakepressure to prevent wheel lockup when brakingsuddenly on wet, snowy or other low-tractionsurfaces. This helps preserve vehicle stability andsteering control in emergency braking situations.
This system supports the driver by providing thestrong braking needed in emergency brakingsituations but with less force on the brake pedalthan would ordinarily be necessary. Brake Assistcomes into action when the driver presses on
the brake pedal with force that exceeds a certainthreshold. While enjoying normal braking responseunder normal driving conditions, the driver caneasily achieve powerful braking in emergenciesand effectively activate ABS, which can furthercontribute to accident avoidance performance.
Nissan led the world in commercializing BrakeAssist technology since its introduction in 1997.
Adding to the functions of ABS and TCS (TractionControl System), VDC automatically controlsbrakes and engine output to help enhancestability when sensors detect that the vehicle mayslip sideways, based on steering, braking andaccelerator pedal operation.

Safety ActivitiesTechnology Overview
In cases where a crash cannot be avoided, additional Nissan technology helps reduce injuries anddamage by activating the brakes, restraining passengers, and applying other measures.
Helps minimize the damage when a collision
is unavoidable
Using a radar sensor, this system measures thedistance from a vehicle being followed and givesan audible and visual warning if it determines thatthe driver should take evasive measures to helpavoid a direct rear-end collision. In addition, if thesystem judges that a collision remains unavoidableeven after driver action, brakes are applied toslow the vehicle and help reduce injuries and
mitigate damage.
Intelligent Brake Assist
A motor tightens the front seatbelts if thesystem determines that the driver is performingemergency braking or if Intelligent Brake Assist isactivated. This helps keep the driver in a postureconducive to performing evasive maneuvers. If acollision cannot be avoided, this technology alsohelps reduce occupant motion so airbags and
other safety measures can operate optimally.
Nissan holds the basic patent on this technology, but isproviding the license to other automakers to promote safer
vehicle performance.

Zone Body construction
Nissans Zone Body combines impact-absorbingstructures (crushable zones) with a high-strengthcabin (occupant zone) to help protect occupants.With the version of the Nissan March (Japan modelname) launched in 2002, Nissan introduced a moreadvanced crash-compatible Zone Body that notonly enhances occupant protection of the hostvehicle, but also reduces aggressiveness to the
other vehicle involved in an accident. In case ofpedestrian involvement, energy-absorbing construc-tion in areas of the vehicles hood, fenders and cowlhelp mitigate head injuries, while energy-absorbingmaterial in the front bumper helps reduce impact tothe legs.
If a crash does occur, the Zone Body, SRS airbag systems and other measures help mitigate injury.
After a crash, systems such as HELPNET can hasten assistance to diminish the danger of secondary damage.

These advanced facilities in Japan are used for
testing safety performance in vehicle-to-vehicle
crashes and occupant protection performance in
rollover accidents. The lab tests head-on collisions
at speeds of up to 120km/h for each vehicle, as
well as offset collisions at angles of between 185
and 85 degrees in 5-degree intervals. Based on
analysis of a vast number of accidents, this labora-
tory enables accident re-creation with a greaterdegree of fidelity to the original circumstances.

SRS* Airbag Systems
In addition to the SRS dual airbag system, Nissan
offers SRS side airbags for chest protection of
front seat occupants and SRS curtain airbags for
head protection of front- and rear-seat passengers
in case of side impact. Nissan was first to install
a drivers seat SRS airbag system as a standard
feature in Japan and has led the industry withadoption of SRS curtain airbag systems, previously
considered a luxury car feature, even on small pas-
senger cars, such as the March, since 2002.

The Active Head Restraint instantly moves forward
to support the head and reduce sudden backward
movement in case the occupants vehicle is struck
from the rear. This is designed to help minimize
stress on the neck and thereby help mitigate the risk
of whiplash and related injuries. Since about half of
Japans traffic accidents are rear-end collisions and
about 90% of those result in neck injuries, Nissan
is moving forward with the adoption of Active HeadRestraint systems in its vehicles.
Front-seat Active Head Restraints
Seatbelts
Seatbelts raise the effectiveness of SRS airbag
systems and other safety measures. In a frontal
collision, a pre-tensioner prepares for impact and a
load limiter reduces post-impact stress on the chest.
A two-stage load limiter matched to front-seat airbagdeployment and deflation characteristics lowers the
belt load, while a lap belt pre-tensioner complements
the shoulder belt. These systems work with Nissans
Front Pre-Crash Seat Belts and other systems for
more effective passenger restraint optimized to
individual vehicle characteristics.

Improving the road-transport environment
ITS Project in Kanagawa Prefecture
In 2006, the ITS Project in Kanagawa Prefecturewas launched with the aim of reducing trafficaccidents and traffic congestion using advancedcommunication technology through the applicationof ITS concepts that regard people, roads andvehicles as an integrated system. The projectfocuses on reducing intersection accidents,improving school zone safety, mitigating trafficcongestion and presenting drivers with informationon the fastest routes. Nissan has made significantprogress in enhancing safety based on vehiclecapabilities, including building more crashworthyvehicles and the introduction of our CARWINGSsystem, which helps predict traffic congestion andsuggests optimal routes on the basis of historicaldata together with realtime traffic information fromVICS, the Vehicle Information and CommunicationSystem. The ITS Project in Kanagawa Prefecturetakes the additional step of linking vehicles withinfrastructure that will enhance safety and mitigate
congestion by enabling communication of road-traffic conditions and alerting drivers to thepresence of other vehicles in the immediate vicinity.After verifying the effectiveness of the ITS Projectin Kanagawa Prefecture, coverage is planned toexpand nationwide and, eventually, beyond Japan.
Pedestrain protection initiative
From December 2005 through March 2006 inYokohama City, Nissan and telecommunicationscompanies tested a new service designed to helpprevent accidents involving children at pedestriancrossings. IC tags were distributed to children andvehicles, and receivers were installed at crossingswith poor visibility and near public parks in theexperimental zone. Based on signals from the
respective IC tags, the system can tell when childrenare near vehicles and warn drivers to proceed withcaution. Nissan is proceeding with this and furtherinitiatives aimed at reducing accidents involvingchildren and pedestrians.

in nursery schools and kindergartens, and provided
videos for group screenings in Japan. In 2005
Nissan expanded the program to citizens aged
65 and over. Since 1998, Nissan North America
has provided the Quest for Safety program, a free
educational seminar to enhance the safety of
children in vehicles by informing caregivers of the
importance of child seats and other safety matters.
In addition, the Nissan Snug Kids program pres-
ents information to help choose child seats. These
ongoing programs are intended as a response to
the fact that, in the USA, traffic accidents are one
of the leading causes of child mortality and about
80% of child seats are used incorrectly.
Safety promotion efforts
Nissan approaches safety not only from the standpoint of vehicle safety and the traffic environment,
but also from the standpoint of the individual, through educational activities and driver training.
