Front seat-mounted side-impact
supplemental air bag and
roof-mounted curtain side-
impact and rollover supplemental
air bag systems
The side air bags are located in the outside
of the seatback of the front seats. The cur-
tain air bags are located in the side roof
rails.All of the information, cautions and
warnings in this manual must be fol-
lowed. The side air bags and curtain air
bags are designed to inflate in higher se-
verity side collisions, although they may in-
flate if the forces in another type of collision are similar to those of a higher severity
impact. They are designed to inflate on the
side where the vehicle is impacted. They
may not inflate in certain side collisions.
Curtain air bags are also designed to inflate
in certain types of rollover collisions or near
rollovers. As a result, certain vehicle move-
ments (for example, during severe off-
roading) may cause the curtain air bags to
inflate.
Vehicle damage (or lack of it) is not always
an indication of proper side air bag and
curtain air bag operation.
When the side air bags and curtain air bags
inflate, a fairly loud noise may be heard,
followed by the release of smoke. This
smoke is not harmful and does not indi-
cate a fire. Care should be taken not to
inhale it, as it may cause irritation and
choking. Those with a history of a breath-
ing condition should get fresh air promptly.
Side air bags, along with the use of seat
belts, help to cushion the impact force on
the chest and pelvic area of the front occu-
pants. Curtain air bags help to cushion the
impact force to the head of occupants in
the front and rear outboard seating posi-
tions. They can help save lives and reduce
serious injuries. However, an inflating side
air bag and curtain air bag may cause
abrasions or other injuries. Side air bags
and curtain air bags do not provide re-
straint to the lower body.
The seat belts should be correctly worn
and the driver and front passenger seated
upright as far as practical away from the
side air bag. Rear seat passengers should
be seated as far away as practical from the
door finishers and side roof rails. The side
air bags and curtain air bags inflate quickly
in order to help protect the occupants. Be-
cause of this, the force of the side air bag
and curtain air bag inflating can increase
the risk of injury if the occupant is too close
to, or is against, these air bag modules dur-
ing inflation. The side air bag will deflate
quickly af ter the collision is over.
The curtain air bag will remain inflated for a
short time.
The side air bags and curtain air bags
operate only when the ignition switch is
placed in the ON position.
Af ter placing the ignition switch in the
ON position, the supplemental air bag
warning light illuminates. The supple-
mental air bag warning light will turn off
af ter about 7 seconds if the system is
operational.

SUPPLEMENTAL AIR BAG WARNING
LIGHT
The supplemental air bag warning light,
displaying
in the instrument panel,
monitors the circuits for the air bag sys-
tems, pretensioner(s) and all related wiring.
When the ignition is placed in the ON or
START position, the supplemental air bag
warning light illuminates for about 7 sec-
onds and then turns off. This means the
system is operational. If any of the following conditions occur, the
front air bag, side air bag and curtain air
bag and pretensioner systems need ser-
vicing:
∙ The supplemental air bag warning light remains on af ter approximately 7 sec-
onds.
∙ The supplemental air bag warning light flashes intermittently.
∙ The supplemental air bag warning light does not come on at all.
Under these conditions, the front air bag,
side air bag and curtain air bag or preten-
sioner systems may not operate properly.
They must be checked and repaired. It is
recommended that you visit a NISSAN
dealer for this service.WARNING
If the supplemental air bag warning
light is on, it could mean that the front
air bag, side air bag, curtain air bag
and/or pretensioner systems will not
operate in an accident. To help avoid
injury to yourself or others, have your
vehicle checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
Repair and replacement
procedure
The front air bags, side air bags, curtain air
bags and pretensioner(s) are designed to
inflate on a one-time-only basis. As a re-
minder, unless it is damaged, the supple-
mental air bag warning light remains illu-
minated af ter inflation has occurred. These
systems should be repaired and/or re-
placed as soon as possible. It is recom-
mended that you visit a NISSAN dealer for
this service.
When maintenance work is required on the
vehicle, the front air bags, side air bags,
curtain air bags, pretensioner(s) and re-
lated parts should be pointed out to the
person performing the maintenance. The
ignition switch should always be placed in
the LOCK position when working under the
hood or inside the vehicle.

eter and odometer. The speedometer is
located on the right side of the meter clus-
ter. The odometer is located within the ve-
hicle information display.
Speedometer
The speedometer indicates vehicle speed.
Odometer/Twin trip odometer
The odometer and the twin trip odometer
1are displayed in the vehicle information

CAUTION
If the gauge indicates coolant tempera-
ture near the hot (H) end of the normal
range, reduce vehicle speed to decrease
temperature. If the gauge is over the
normal range, stop the vehicle as soon
as safely possible. If the engine is over-
heated, continued operation of the ve-
hicle may seriously damage the engine.
For additional information, refer to “If
your vehicle overheats” in the “In case
of emergency ” section of this manual
for immediate action required.
FUEL GAUGE
The gauge indicates theapproximatefuel
level in the tank.
The gauge may move slightly during brak-
ing, turning, acceleration, or going up or
down hills.
The gauge needle returns to 0 (Empty) af-
ter the ignition switch is placed in the OFF
position.
The low fuel warning message shows in
the vehicle information display when the
amount of fuel in the tank is getting low. Refill the fuel tank before the gauge reg-
isters 0 (Empty).
The
indicates that the fuel-filler
door is located on the driver’s side of the
vehicle.
CAUTION
∙ If the vehicle runs out of fuel, theMalfunction Indicator Light (MIL) may
come on. Refuel as soon as possible.
Af ter a few driving trips, the
light
should turn off. If the light remains on
af ter a few driving trips, have the ve-
hicle inspected. It is recommended
that you visit a NISSAN dealer for this
service.

Zone variation change procedure
The difference between magnetic north
and geographical north is known as vari-
ance. In some areas, this difference can
sometimes be great enough to cause false
compass readings. Follow these instruc-
tions to set the 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. Place the ignition switch in the ON po- sition.
3. Press the
button in for 5 seconds
until the current zone entry number is
displayed.
4. Press the
button repeatedly until
the desired zone entry number is dis-
played.

position, the light warns of a low brake fluid level. If the light comes on while the engine
is running with the parking brake not ap-
plied, stop the vehicle and perform the fol-
lowing:
1. Check the brake fluid level. Add brake fluid as necessary. For additional infor-
mation, refer to “Brake fluid” in the “Do-
it-yourself ” section of this manual.
2. If the brake fluid level is correct, have the warning system checked. It is rec-
ommended that you visit a NISSAN

WARNING
∙ Your brake system may not be work-ing properly if the warning light is on.
Driving could be dangerous. If you
judge it to be safe, drive carefully to
the nearest service station for repairs.
Otherwise, have your vehicle towed
because driving it could be
dangerous.
∙ Pressing the brake pedal with the en- gine stopped and/or a low brake fluid
level may increase your stopping dis-
tance and braking will require greater
pedal effort as well as pedal travel.
