Supplemental air bag system
The driver supplemental air bag is located in
the center of the steering wheel. The pas-
senger supplemental air bag is located in
the top right section of the instrument panel.
These systems are designed to meet optional
certification requirements under U.S. regula-
tions. They are also permitted in Canada. The
optional certification allows air bags to be
designed to inflate somewhat less forcefully
than previously.However, all of the informa-tion, cautions and warnings in this manual
still apply and must be followed.
The supplemental air bag system is de-
signed to inflate in higher severity frontal
collisions, although it may inflate if the
forces in another 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 supplemental air bag
system operation.
The supplemental air bag system has dual
stage inflators for both the driver and pas-
senger air bags. The system monitors infor-
mation from the crash zone sensor, the
diagnosis sensor unit and seat belt buckle
sensors that detect if the seat belts are
fastened. Inflator operation is based on the
severity of a collision and whether the seat
belts are being used.
When the supplemental air bag inflates, a
fairly loud noise may be heard, followed by
the release of smoke. This smoke is not
harmful and does not indicate a fire. Care
should be taken not to intentionally inhale it,
as it may cause irritation and choking.
Those with a history of a breathing condition
should get fresh air promptly.

OUTSIDE TEMPERATURE DIS-
PLAY
Push the MODE switch when the ignition
key is in the ACC or ON position. The
outside temperature will be displayed in ÉF.
OPush the MODE switch to change from
ÉF to ÉC.
OWhen the outside temperature is be-
tween 130ÉF (55ÉC) and 158ÉF (70ÉC),
the display shows 130ÉF (55ÉC).
OWhen the outside temperature is
lower than -40ÉF (-40ÉC) or higherthan 158ÉF (70ÉC), the display shows
onlyÐÐÐthough it is operating.
This is not a malfunction.
OThe outside temperature sensor is
located in front of the radiator. The
sensor may be affected by road or
engine heat, wind direction and other
driving conditions. The display may
differ from the actual outside tem-
perature or the temperature dis-
played on various signs or bill-
boards.
OTemperature display will not update
unless the vehicle is moving faster
than 12 mph (20 km/h), or the ignition
switch has been OFF for 4 hours.COMPASS DISPLAY
Push the MODE switch when the ignition
key is in the ACC or ON position. The
direction will be displayed.
Zone variation change procedure
The difference between magnetic north and
geographical north is known as variance. In
some areas, this difference can sometimes
be great enough to cause false compass
readings. Follow these instructions to setthe variance for your particular location if
this happens:
1. Establish your location on the zone map.
Refer to the illustration. Record your
zone number.
2. Push the MODE switch in for five sec-
onds until the current zone entry number
is displayed.
3. Press the MODE switch repeatedly until
the new zone entry number is displayed.
Once the desired zone number is displayed,
stop pressing the MODE switch and the
display will show compass direction within a
few seconds.

WARNING
OWhile driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.
OIf 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 the brakes. Do this until the brakes
return to normal. Avoid driving the vehicle at
high speeds until the brakes function cor-
rectly.
ANTI-LOCK BRAKE SYSTEM (ABS)
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 dis-
tances.
Normal operation
The anti-lock brake system does not oper-
ate at speeds below 3 to 6 MPH (5 to 10
km/h). (The speeds vary according to road
conditions.)
When driving, the anti-lock brake system
controls the wheels so they will not lock
when braking abruptly or when braking on a
slippery road. Thus, difficult steering and
swerving of the vehicle due to locked
wheels is minimized. The system detects
the wheel rotation rate and electronically
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 brak-ing is not a problem, but indicates that the
system is functioning.
Self-test feature
The anti-lock brake system consists of elec-
tronic sensors and hydraulic solenoids con-
trolled by a computer. The computer has a
built-in diagnostic feature that tests the sys-
tem 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
pulsation 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 in the
dashboard. The brake system then operates
normally, but without anti-lock assistance.
If an abnormality occurs in the system, the
anti-lock function will cease but the ordinary
brakes will continue to operate normally. The
ABS brake warning light will then come on.
If the light comes on while you are driving,
contact an authorized NISSAN dealer for
repair.
