the crash zone sensor, the diagnosis sensor unit,
seat belt buckle switches, occupant classifica-
tion sensor (pressure sensor) and passenger
seat belt tension sensor. Inflator operation is
based on the severity of a collision and seat belt
usage of the driver. For the front passenger, it
additionally monitors the weight of an occupant
or object on the seat and seat belt tension.
Based on information from the sensors, only one
front air bag may inflate in a crash, depending on
the crash severity and whether the front occu-
pants are belted or unbelted. Additionally, the
front passenger air bag may be automatically
turned OFF under some conditions, depending
on the weight detected on the passenger seat
and how the seat belt is used. If the front
passenger air bag is OFF, the passenger air bag
status light will be illuminated (if the seat is
unoccupied, the light will not be illuminated, but
the air bag will be off.). See “Front passenger air
bag and status light” later in this section for
further details. One front air bag inflating does
not indicate improper performance of the sys-
tem.
If you have any questions about your air bag
system, contact NISSAN or a NISSAN dealer. If
you are considering modifications of your vehicle
due to a disability, you may also contact
NISSAN. Contact information is contained in thefront of this Owner’s Manual.
When a supplemental front air bag inflates, a
fairly loud noise may be heard, followed by
release of smoke. This smoke is not harmful and
does not indicate a fire. Care should be taken to
not inhale it, as it may cause irritation and
choking. Those with a history of a breathing
condition should get fresh air promptly.
Supplemental front air bags, along with the use
of seat belts, help to cushion the impact force on
the head and chest of the front occupants. They
can help save lives and reduce serious injuries.
However, an inflating front air bag may cause
facial abrasions or other injuries. Front air bags
do not provide restraint to the lower body.
Even with NISSAN advanced air bags, seat belts
should be correctly worn and the driver and
passenger seated upright as far as practical
away from the steering wheel or instrument
panel. The supplemental front air bags inflate
quickly in order to help protect the front occu-
pants. Because of this, the force of the front air
bag inflating can increase the risk of injury if the
occupant is too close to, or is against, the front
air bag module during inflation.
The front air bags deflate quickly after a collision.
The supplemental front air bags operateonly when the ignition switch is in the ON
or START position.
After turning the ignition switch to the ON
position, the supplemental air bag warning
light illuminates. The supplemental air bag
warning light will turn off after about 7
seconds if the system is operational.1-48

in the passenger seat status. For example, if a
large adult who is sitting in the front passenger
seat exits the vehicle, the passenger air bag
status light will change from OFF to ON for a few
seconds and then to OFF. This is normal system
operation and does not indicate a malfunction.
If a malfunction occurs in the front passenger air
bag system, the supplemental air bag warning
light
, located in the meter and gauges
area, will blink. Have the system checked by a
NISSAN dealer.
Other supplemental front air bag
precautions
WARNING
Do not place any objects on the
steering wheel pad or on the instru-
ment panel. Also, do not place any
objects between any occupant and
the steering wheel or instrument
panel. Such objects may become
dangerous projectiles and cause in-
jury if the supplemental front air bag
inflates.Immediately after inflation, several
front air bag system components will
be hot. Do not touch them; you may
severely burn yourself.
No unauthorized changes should be
made to any components or wiring of
the supplemental air bag system.
This is to prevent accidental inflation
of the supplemental air bag or dam-
age to the supplemental air bag sys-
tem.
Do not make unauthorized changes
to your vehicle’s electrical system,
suspension system or front end
structure. This could affect proper
operation of the supplemental air
bag system.
Tampering with the supplemental
front air bag system may result in
serious personal injury. Tampering
includes changes to the steering
wheel and the instrument panel as-
sembly by placing material over the
steering wheel pad and above the
instrument panel or by installing ad-ditional trim material around the air
bag system.
Modifying or tampering with the front
passenger seat may result in serious
personal injury. For example, do not
change the front seats by placing
material on the seat cushion or by
installing additional trim material,
such as seat covers, on the seat that
are not specifically designed to as-
sure proper air bag operation. Addi-
tionally, do not stow any objects un-
der the front passenger seat or the
seat cushion and seatback. Such ob-
jects may interfere with the proper
operation of the occupant classifica-
tion sensor (pressure sensor).
No unauthorized changes should be
made to any components or wiring of
the seat belt system. This may affect
the supplemental front air bag sys-
tem. Tampering with the seat belt
system may result in serious per-
sonal injury.

d. You have had an accident involv-
ing damage to the exhaust system,
underbody, or rear of the vehicle.
THREE-WAY CATALYSTThe three-way catalyst is an emission control
device installed in the exhaust system. Exhaust
gases in the converter are burned at high tem-
peratures to help reduce pollutants.
WARNING
The exhaust gas and the exhaust sys-
tem are very hot. Keep people, ani-
mals or flammable materials away
from the exhaust system compo-
nents.
Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.
CAUTION
Do not use leaded gasoline. Deposits
from leaded gasoline will seriously
reduce the three-way catalyst’s abil-
ity to help reduce exhaust pollutants.
Keep your engine tuned up. Malfunc-
tions in the ignition, fuel injection, or
electrical systems can cause overrich
fuel flow into the three-way catalyst,
causing it to overheat. Do not keep
driving if the engine misfires, or if
noticeable loss of performance or
other unusual operating conditions
are detected. Have the vehicle in-
spected promptly by a NISSAN
dealer.
Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, damag-
ing the three-way catalyst.
Do not race the engine while warm-
ing it up.
Do not push or tow your vehicle to
start the engine.
TIRE PRESSURE MONITORING
SYSTEM (TPMS)Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle plac-
ard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated
on the vehicle placard or tire inflation pressure
label, you should determine the proper tire infla-
tion pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel effi-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver’s
responsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
Starting and driving
5-3

to trigger illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS
malfunction indicator is combined with the low
tire pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the
malfunction exists. When the malfunction indica-
tor is illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replacement
or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or alter-
nate tires and wheels allow the TPMS to con-
tinue to function properly.Additional informationThe TPMS does not monitor the tire pressure
of the spare tire.
The TPMS will activate only when the vehicle
is driven at speeds above 16 MPH (25 km/h).
Also, this system may not detect a suddendrop in tire pressure (for example a flat tire
while driving).
The low tire pressure warning light does not
automatically turn off when the tire pressure
is adjusted. After the tire is inflated to the
recommended pressure, the vehicle must be
driven at speeds above 16 MPH (25 km/h) to
activate the TPMS and turn off the low tire
pressure warning light. Use a tire pressure
gauge to check the tire pressure.
Tire pressure rises and falls depending on the
heat caused by the vehicle’s operation and
the outside temperature. Low outside tem-
perature can lower the temperature of the air
inside the tire which can cause a lower tire
inflation pressure. This may cause the low tire
pressure warning light to illuminate. If the
warning light illuminates in low ambient tem-
perature, check the tire pressure for all four
tires.
You can also check the pressure of all tires
(except the spare tire) on the display screen.
The order of the tire pressure figures dis-
played on the screen does not correspond
with the actual order of the tire position. See
“Tire pressure information” in the “4. Display
screen, heater, air conditioner and audio sys-
tem” section.
For additional information, see “Low tire pres-sure warning light” in the “2. Instruments and
controls” section and “Tire pressure monitoring
system (TPMS)” in the “6. In case of emergency”
section.
WARNING
If the low tire pressure warning light
illuminates while driving, avoid sud-
den steering maneuvers or abrupt
braking, reduce vehicle speed, pull
off the road to a safe location and
stop the vehicle as soon as possible.
Serious vehicle damage could occur
and may lead to an accident and
could result in serious personal in-
jury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still illuminates while driving af-
ter adjusting the tire pressure, a tire
may be flat. If you have a flat tire,
replace it with a spare tire as soon as
possible. (See “Flat tire” in the “In

Tire inflation pressureCheck the tire pressures (including the
spare) often and always prior to long
distance trips. The recommended tire
pressure specifications are shown on the
F.M.V.S.S./C.M.V.S.S. label and/or the
Tire and Loading Information label under
the “Cold Tire (Inflation) Pressure” head-
ing. The Tire and Loading Information
label is affixed to the driver side center
pillar. Tire pressures should be checked
regularly because:
Most tires naturally lose air over time.
Tires can lose air suddenly when
driven over potholes or other objects
or if the vehicle strikes a curbwhile
parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle has
been parked for 3 or more hours, or
driven less than 1 mile (1.6 km) at mod-
erate speeds.Incorrect tire pressure, including un-
der inflation, may adversely affect
tire life and vehicle handling.
WARNING
Improperly inflated tires can fail
suddenly and cause an acci-
dent.
The Gross Vehicle Weight Rat-
ing (GVWR) is located on the
F.M.V.S.S./C.M.V.S.S. label. The
vehicle weight capacity is indi-
cated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capac-
ity. Overloading your vehicle
may result in reduced tire life,
unsafe operating conditions
due to premature tire failure, or
unfavorable handling charac-
teristics and could also lead to
a serious accident. Loading be-
yond the specified capacity mayalso result in failure of other
vehicle components.
Before taking a long trip, or
whenever you heavily load your
vehicle, use a tire pressure
gauge to ensure that the tire
pressures are at the specified
level.
Do not drive your vehicle over
85 MPH (137 km/h) unless it is
equipped with high speed rated
tires. Driving faster than 85
MPH (137 km/h) may result in
tire failure, loss of control and
possible injury.

garding tires, refer to “Impor-
tant Tire Safety Information”
(US) or “Tire Safety Informa-
tion” (Canada) in the Warranty
Information Booklet.

Checking the tire pressure1. Remove the valve stem cap from the
tire.
2. Press the pressure gauge squarely
onto the valve stem. Do not press too
hard or force the valve stem sideways,
or air will escape. If the hissing sound
of air escaping from the tire is heard
while checking the pressure, reposi-
tion the gauge to eliminate this leak-
age.3. Remove the gauge.
4. Read the tire pressure on the gauge
stem and compare it to the specifica-
tion shown on the Tire and Loading
Information label.
5. Add air to the tire as needed. If too
much air is added, press the core of
the valve stem briefly with the tip of the
gauge stem to release pressure. Re-
check the pressure and add or release
air as needed.
6. Install the valve stem cap.
7. Check the pressure of all other tires,
including the spare.

WARNING
The spare tire should be used for
emergency use only. It should be re-
placed with the standard tire at the
first opportunity to avoid possible
tire or differential damage.
Drive carefully while the TEMPO-
RARY USE ONLY spare tire is in-
stalled. Avoid sharp turns and abrupt
braking while driving.
Periodically check spare tire inflation
pressure. Always keep the pressure
of the TEMPORARY USE ONLY spare
tire at 60 psi (420 kPa, 4.2 bar).
With the TEMPORARY USE ONLY
spare tire installed do not drive the
vehicle at speeds faster than 50 MPH
(80 km/h).
When driving on roads covered with
snow or ice, the TEMPORARY USE
ONLY spare tire should be used on
the rear wheel and the original tire
used on the front wheels (drivewheels). Use tire chains only on the
front (original) tires.
Tire tread of the TEMPORARY USE
ONLY spare tire will wear at a faster
rate than the standard tire. Replace
the spare tire as soon as the tread
wear indicators appear.
Do not use the spare tire on other
vehicles.
Do not use more than one spare tire
at the same time.
Do not tow a trailer when the TEM-
PORARY USE ONLY spare tire is in-
stalled.
CAUTION
Do not use tire chains on a TEMPO-
RARY USE ONLY spare tire. Tire
chains will not fit properly and may
cause damage to the vehicle.
Because the TEMPORARY USE
ONLY spare tire is smaller than theoriginal tire, ground clearance is re-
duced. To avoid damage to the ve-
hicle, do not drive over obstacles.
Also, do not drive the vehicle through
an automatic car wash since it may
get caught.

ing above 2,000 lb (907 kg). Suitable
genuine NISSAN hitches for pickup
trucks and sport utility vehicles are
available at a NISSAN dealer.
Do not use axle-mounted hitches.
The hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
Do not modify the vehicle exhaust
system, brake system, etc. to install atrailer hitch.
After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.
Regularly check that all trailer hitch
mounting bolts are securely
mounted.
To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.
Tire pressuresWhen towing a trailer, inflate the ve-
hicle tires to the recommended cold
tire pressure indicated on the Tire and
Loading Information label.
Trailer tire condition, size, load rating
and proper inflation pressure should
be in accordance with the trailer and
tire manufacturers’ specifications.
Safety chainAlways use a suitable chains between your
vehicle and the trailer. The safety chains should
be crossed and should be attached to the hitch,
not to the vehicle bumper or axle. Be sure to
leave enough slack in the chain to permit turning
corners.Trailer lights
CAUTION
When splicing into the vehicle electrical
system, a commercially available
power-type module/converter must be
used to provide power for all trailer
lighting. This unit uses the vehicle bat-
tery as a direct power source for all
trailer lights while using the vehicle tail
light, stoplight and turn signal circuits
as a signal source. The module/
converter must draw no more than 15
milliamps from the stop and tail lamp
circuits. Using a module/converter that
exceeds these power requirements may
damage the vehicle’s electrical system.
