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.

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.
If the battery terminal is disconnected,
push the trip computer mode switch more
than 1 second to activate the computer.
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 if
you wish to return to the mode that was selected
before the warning occurred. The ICY indicatorwill continue blinking 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
driving conditions. The display may differ from the
actual ambient temperature or the temperature
displayed on various signs or billboards.
Distance to empty (dte—mile or km)
The distance to empty (dte) mode provides you
with an estimation of the distance that can be
driven before refueling. The dte is constantly be-
ing calculated, based on the amount of fuel in the
fuel tank and the actual fuel consumption.
The display is updated every 30 seconds.
The dte mode includes a low range warning
feature: when the fuel level is low, the dte mode is
automatically selected and the digits blink in or-
der to draw the driver’s attention. Press the
change button if you wish to return to the mode
that was selected before the warning occurred.
The dte mark (dte) will remain blinking until the
vehicle is refueled.
When the fuel level drops even lower, the dte
display will change to (----) .NOTE:
cIf the amount of fuel added while the
ignition switch is OFF is small, the dis-
play just before the ignition switch is
turned OFF may continue to be dis-
played.
cWhen driving uphill or rounding curves,
the fuel in the tank shifts, which may
momentarily change the display.Average fuel consumption (Mpg or
l/100km)
The average fuel consumption mode shows the
average fuel consumption since the last reset.
Resetting is done by pressing the change button
for more than approximately 1 second. The dis-
play is updated every 30 seconds. At about the
first 1/3 miles (500 m) after a reset, the display
shows (----) .
Average speed (MPH or km/h)
The average speed mode shows the average
vehicle speed since last reset. Resetting is done
by pressing the change button for more than
approximately 1 second. The display is updated
every 30 seconds. The first 30 seconds after a
reset, the display shows (----) .

WARNING
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
cIf the engine is not running or is turned
off while driving, the power assist for
the brakes will not work. Braking will be
harder.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing the brake pedal to
heat up the brakes. Do this until the brakes return
to normal. Avoid driving the vehicle at high
speeds until the brakes function correctly.
ANTI-LOCK BRAKE SYSTEM (ABS)
(if so equipped)
The anti-lock brake system controls the brakes so
the wheels do not lock when braking abruptly or
when braking on slippery surfaces. The system
detects the rotation speed at each wheel andvaries 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.
