Supplemental front air bag system
The driver supplemental front air bag is located in
the center of the steering wheel. The passenger
supplemental front air bag is mounted in the
dashboard above the glove box.
These systems are designed to meet optional
certification requirements under U.S. regulations.They are also permitted in Canada. The optional
certification allows the front air bags to be de-
signed to inflate somewhat less forcefully than
previously.However, all of the information,
cautions and warnings in this manual still
apply and must be followed.
The supplemental front air bag system is de-
signed to inflate in higher severity frontal colli-
sions, although it may inflate if the forces in an-
other type of collision are similar to those of a
higher severity frontal impact. It may not inflate in
certain frontal collisions. Vehicle damage (or lack
of it) is not always an indication of proper supple-
mental front air bag system operation.

SUPPLEMENTAL AIR BAG
WARNING LIGHT
The supplemental air bag warning light,
displayingin the instrument panel, moni-
tors the circuits of the supplemental front air
bags, pre-tensioner seat belt and supplemental
side air bag (if so equipped) systems. The circuits
monitored by the supplemental air bag warning
light are the diagnosis sensor unit, supplemental
air bag modules, pre-tensioner seat belts and all
related wiring.
When the ignition key is in the ON or START
position, the supplemental air bag warning lightilluminates for about 7 seconds and then turns
off. This means the system is operational.
If any of the following conditions occur, the
supplemental front air bag, supplemental side air
bag and pre-tensioner seat belt systems need
servicing:
cThe supplemental air bag warning light re-
mains on after approximately 7 seconds.
cThe supplemental air bag warning light
flashes intermittently.
cThe supplemental air bag warning light does
not come on at all.
Under these conditions, the supplemental front
air bag, supplemental side air bag or pre-
tensioner seat belt systems may not operate
properly. It must be checked and repaired. Take
your vehicle to the nearest NISSAN dealer.
WARNING
If the supplemental air bag warning light
is on, it could mean that the supplemental
front air bag or supplemental side air bag
system will not operate in an accident. To
help avoid injury to yourself or others,
have your vehicle checked by a NISSAN
dealer as soon as possible.
Repair and replacement procedure
The supplemental front air bags, pre-tensioner
seat belts and supplemental side air bags (if so
equipped) are designed to inflate on a one-time-
only basis. As a reminder, unless it is damaged,
the supplemental air bag warning light remains
illuminated after inflation has occurred. Repair
and replacement of these supplemental air bag
systems should be done only by a NISSAN
dealer.
When maintenance work is required on the ve-
hicle, the supplemental front air bags, supple-
mental side air bags (if so equipped) , pre-
tensioner seat belts and related parts should be
pointed out to the person performing the mainte-
nance. The ignition key should always be in the
LOCK position when working under the hood or
inside the vehicle.

Odometer/Twin trip odometer
The odometer/twin trip odometers2is displayed
when the ignition key is in the ON position.
The odometer records the total distance the ve-
hicle has been driven.
The twin trip odometer records the distance of
individual trips.Changing the display:
For vehicles equipped with twin trip odometer,
pushing the change button
s3changes the dis-
play as follows:
ODO (odometer)!Trip
!Trip!
ODO
For vehicles equipped with trip computer, pushing
the change button
s3changes the display as
follows:
Trip!Trip!Outside air tempera-
ture!Distance to Empty!Average fuel con-
sumption!Average speed!Journey time!
Trip
Resetting the trip odometer:
Pushing the change button for more than 1 sec-
ond resets the trip odometer to zero.
TRIP COMPUTER (if so equipped)
The display of the trip computer is situated in the
speedometer display. When the ignition is turned
to ON, the display scrolls all the modes of the trip
computer and then shows the mode chosen be-
fore the ignition switch is turned OFF.
When the ignition switch is turned to ON, modes
of the trip computer can be selected by pushing
the trip computer change button. The following
modes can be selected:
Outside air temperature (ICY-°F or °C)
The outside air temperature is displayed in °F or °C.
The outside air temperature mode includes a low
temperature warning feature: below 37°F (3°C) ,
the outside air temperature mode is automatically
selected and ICY will illuminate in order to draw
the driver’s attention. Press the change button to
toggle to the next mode, if desired. The ICY
indicator will remain illuminated as long as the
temperature remains below 39°F (4°C) .
The ambient temperature sensor is located in
front of the radiator. The sensor may be affected
by road or engine heat, wind directions and other

varies the brake fluid pressure to prevent each
wheel from locking and sliding. By preventing
wheel lockup, the system helps the driver main-
tain steering control and helps to minimize swerv-
ing and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Normal operation
The anti-lock brake system does not operate at
speeds below3-6MPH(5-10km/h) . (The
speeds vary according to road conditions.)
When driving, the anti-lock brake system con-
trols the wheels so they will not lock when brak-
ing abruptly or when braking on a slippery road.
Thus, difficult steering and swerving of the ve-
hicle due to locked wheels is minimized. The
system detects the wheel rotation rate and elec-
tronically controls the pressure applied to each
brake. Slight vibration on the brake pedal accom-
panied by noise usually occurs while the ABS
system is operating. Such vibration and noise
encountered during abrupt braking is not a prob-lem, but indicates that the system is functioning
properly. However, the pulsation may indicate
that road conditions are hazardous and extra care
is required while driving.
Self-test feature
The anti-lock brake system consists of electronic
sensors and hydraulic solenoids controlled by a
computer. The computer has a built-in diagnostic
feature that tests the system each time you start
the engine and move the vehicle at a low speed in
forward or reverse. When the self-test occurs,
you may hear a ‘‘clunk’’ noise and/or feel a pulsa-
tion in the brake pedal. This is normal and is not
an indication of any malfunction. If the computer
senses any malfunction, it switches the anti-lock
brake system off and turns on the ABS brake
warning light on the instrument panel. The brake
system then operates normally, but without anti-
lock assistance.
If a malfunction occurs in the system, the anti-
lock function will not operate, but the standard
vehicle brake system will continue to operate
normally. The ABS brake warning light will then
come on.
If the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.
