Air bag system
(If so equipped)
The driver air bag is located in the center of
the steering wheel; the front passenger air
bag is mounted in the dashboard above the
glove box. The supplemental air bag system
is designed to inflate in higher severity fron-
tal 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 air bag operation.
When the supplemental air bag inflates, afairly loud noise may be heard, followed by
the release of smoke. This smoke is not
harmful and does not indicate a fire, but
care should be taken to not intentionally
inhale it, as it may cause irritation and
choking. Those with a history of breathing
trouble should get fresh air promptly.
The supplemental air bags, along with the
use of the seat belts, help to cushion the
impact force on the face and chest of the
occupant. They can help save lives and
reduce serious injuries. However, an inflat-
ing air bag may cause facial abrasions or
other injuries. Air bags do not provide re-straint to the lower body.
The seat belts should be correctly worn and
the driver and passenger be seated upright
as far as practical away from the steering
wheel or dashboard. Since the air bag in-
flates quickly in order to help protect the
occupant, the force of the air bag inflating
can increase the risk of injury if the occu-
pant is too close to or is against the air bag
module during inflation.
The supplemental air bag deflates quickly
after a collision.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
WARNING
cRight after inflation, several supple-
mental air bag system components
will be hot. Do not touch them; you
may severely burn yourself.
c
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 damage
to the supplemental air bag system.

cTampering with the supplemental air
bag system may result in serious
personal injury. Tampering includes
changes to the steering wheel and
the instrument panel assembly by
placing material over the steering
wheel pad and above the instrument
panel, or by installing additional trim
material around the supplemental air
bag system.
cDo not attach any objects to the
steering wheel pad and to 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 air bag inflates.cWork around and on the supplemen-
tal air bag system should be done by
an authorized NISSAN dealer. Instal-
lation of electrical equipment should
also be done by an authorized NIS-
SAN dealer. The yellow SRS wiring
should not be modified or discon-
nected. Unauthorized electrical test
equipment and probing devices
should not be used on the supple-
mental air bag system.

2. Loosen each wheel nut one or two turns
by turning counterclockwise with the
wheel nut wrench.Do not remove the
wheel nuts until the tire is off the
ground.
3. Carefully raise the vehicle until the tire
clears the ground. Remove the wheel
nuts, and then remove the wheel.
CAUTION
cNever get under the vehicle while it is
supported only by the jack.cUse the jack provided with your ve-
hicle. Do not use the jack provided
with your vehicle on other vehicles.
The jack is designed only for lifting
your vehicle during a tire change.
cTo lift the vehicle, securely hold the
jack lever and rod with both hands as
shown above.
cUse the correct jack-up points; never
use any other part of the vehicle for
jack support.cNever jack up the vehicle more than
necessary.
cNever use blocks on or under the
jack.
cDo not start or run engine while ve-
hicle is on the jack as it may cause
the vehicle to move.
cDo not allow passengers to stay in
the vehicle while it is on the jack.
cDo not raise the vehicle using a
bumper jack.
cNever run the engine with a wheel off
the ground. It may cause the vehicle
to move.
This is especially true for models
equipped with limited slip differen-
tial carrier.

CAUTION
cAfter rotating the tires, adjust the tire
pressure.
cRetighten the wheel nuts after the
wheels have been run for the first 600
miles (1,000 km) (also in cases of a
flat tire, etc.).
cDo not include the T-type spare tire or
any other small size spare tire in the
tire rotation.
Tire wear and damage
CAUTION
Tires should be periodically inspected
for wear, cracking, bulging, or objects
caught in the tread. If excessive wear,
cracks, bulging, or deep cuts are
found, the tire should be replaced.
The original tires have a built-in tread
wear indicator. When the wear indicator
is visible, the tire should be replaced.
Improper service for a T-type spare tire
may result in serious personal injury. Ifit is necessary to repair the T-type
spare tire, contact your NISSAN dealer.
Changing tires and wheels
When replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. Recommended types
and sizes are shown in ``Wheels and tires''
in the ``Technical information'' section. The
use of tires other than those recommended,
or the mixed use of tires of different brands,
construction (bias, bias-belted or radial), or
tread patterns can adversely affect the ride,
braking, handling, ground clearance, body-
to-tire clearance, snow chain clearance,
speedometer calibration, headlight aim and
bumper height.Some of these effects may
lead to accidents and could result in
serious personal injury.
If the wheels are changed for any reason,
always replace with wheels which have the
same offset dimension. Wheels of a different
offset could cause early tire wear, poor
vehicle handling characteristics and/or inter-
ference with the brake discs/drums. Such
interference can lead to decreased braking
efficiency and/or early brake pad/shoe wear.

CAUTION
Do not install a deformed wheel or tire
even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warning.
Wheel balance
Unbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore,
they should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balanc-
ing the front wheels on the vehicle could
lead to transmission damage.
Care of wheels
cWash the wheels when washing the ve-
hicle to maintain their appearance.
cClean the inner side of the wheels when
the wheel is changed or the underside of
the vehicle is washed.
cDo not use abrasive cleaners when
washing the wheels.
cInspect wheel rims regularly for dents or
corrosion. Such damage may cause loss
of pressure or poor seal at the tire bead.cNISSAN recommends waxing the road
wheels to protect against road salt in
areas where it is used during winter.
Spare tire (T-type spare tire)
Observe the following precautions if the T-type
spare tire must be used, otherwise your vehicle
could be damaged or involved in an accident.
CAUTION
cThe T-type spare tire should be used
only for emergency. It should be re-
placed by the standard tire at the first
opportunity.
cDrive carefully while the T-type spare
tire is installed.
Avoid sharp turns and abrupt braking
while driving.
cPeriodically check tire inflation pres-
sure, and always keep it at 60 psi (420
kPa, 4.2 bar).
cDo not drive your vehicle at speeds
faster than 50 MPH (80 km/h).
cDo not use tire chains on a T-type
spare tire. Tire chains will not fit
properly on the T-type spare tire and
may cause damage to the vehicle.cWhen driving on roads covered with
snow or ice, the T-type spare tire
should be used on the rear wheel and
the original tire used on the front
wheels (drive wheels). Use tire chains
only on the front two original tires.
cTire tread of the T-type spare tire will
wear at a faster rate than the original
tire. Replace the T-type spare tire as
soon as the tread wear indicators
appear.
cBecause the T-type spare tire is
smaller than the original tire, ground
clearance is reduced. To avoid dam-
age to the vehicle do not drive over
obstacles. Also do not drive the ve-
hicle through an automatic car wash
since the smaller tire may get caught
in the track.
cDo not use the T-type spare tire on
other vehicles.
cDo not use more than one T-type
spare tire at the same time.
cDo not tow a trailer while the T-type
spare tire is installed.

Tire rotation*Tires should be rotated every
7,500 miles (12,000 km).
Wheel alignment and balanceIf the ve-
hicle should pull to either side while driving
on a straight and level road, or if you detect
uneven or abnormal tire wear, there may be
a need for wheel alignment.
If the steering wheel or seat vibrates at
normal highway speeds, wheel balancing
may be needed.
Windshield wiper blades*Check for
cracks or wear if they do not wipe properly.
Doors and engine hoodCheck that all
doors and the engine hood operate prop-
erly. Also ensure that all latches lock se-
curely. Lubricate hinges, latches, rollers and
links if necessary. Make sure the secondary
latch keeps the hood from opening when
the primary latch is released.
When driving in areas using road salt or
other corrosive materials, check lubrication
frequently.
Lights*Make sure the headlights, stop
lights, tail lights, turn signal lights, and other
lights are all operating properly and installed
securely. Also check headlight aim.INSIDE THE VEHICLE
The maintenance items listed here should
be checked on a regular basis, such as
when performing periodic maintenance,
cleaning the vehicle, etc.
Additional information on the following
items with ``*'' is found in the ``Do-it-
yourself operations'' section.
Warning lights and chimesMake sure all
warning lights and chimes are operating
properly.
Windshield wiper and washer*Check that
the wipers and washer operate properly and
that the wipers do not streak.
Windshield defrosterCheck that the air
comes out of the defroster outlets properly
and in sufficient quantity when operating the
heater or air conditioner.
Steering wheelCheck for changes in the
steering conditions, such as excessive free-
play, hard steering or strange noises.
SeatsCheck seat position controls such as
seat adjusters, seatback recliner, etc. to
ensure they operate smoothly and all
latches lock securely in every position.
Check that the head restraints move up anddown smoothly and the locks (if so
equipped) hold securely in all latched posi-
tions.
Seat beltsCheck that all parts of the seat
belt system (e.g. buckles, anchors, adjust-
ers and retractors) operate properly and
smoothly, and are installed securely. Check
the belt webbing for cuts, fraying, wear or
damage.
Accelerator pedalCheck the pedal for
smooth operation and make sure the pedal
does not catch or require uneven effort.
Keep the floor mats away from the pedal.
Clutch pedal*Make sure the pedal oper-
ates smoothly and check that it has the
proper free travel.
BrakesCheck that the brakes do not pull
the vehicle to one side when applied.
Brake pedal*Check the pedal for smooth
operation and make sure it has the proper
distance under it when depressed fully.
Check the brake booster function. Be cer-
tain to keep floor mats away from the pedal.
Parking brake*Check that the lever has
the proper travel and confirm that your
vehicle is held securely on a fairly steep hill

After the hitch is removed, seal the bolt
holes to prevent exhaust fumes, water
or dust from entering the passenger
compartment.
cRegularly check that all hitch mounting
bolts are securely mounted.
Tire pressures
cWhen towing a trailer, inflate the vehicle
tires to the recommended cold tire pres-
sure indicated on the tire placard (lo-
cated on the driver side center pillar.)
cTrailer tire condition, size, load rating
and proper inflation pressure should be
in accordance with the trailer and tire
manufacturers' specifications.
Safety chain
Always use a suitable chain between your
vehicle and the trailer. The chain 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
Trailer lights should comply with federal
and/ or local regulations. When wiring thevehicle for towing, connect the stop and tail
light pickup into the vehicle electrical circuit.
Trailer brakes
If your trailer is equipped with a braking
system, make sure it conforms to federal
and/or local regulations and that it is prop-
erly installed.
CAUTION
Never connect a trailer brake system
directly to the vehicle brake system.
Pre-towing tips
cBe certain your vehicle maintains a level
position when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if
it has an abnormal nose-up or nose- down
condition; check for improper tongue load,
overload, worn suspension or other pos-
sible causes of either condition.
cAlways secure items in the trailer to
prevent load shifts while driving.
cBe certain your rear view mirrors con-
form to all federal, state or local regula-
tions. If not, install any mirrors required
for towing before driving the vehicle.
Trailer towing tips
In order to gain skill and an understanding
of the vehicle's behavior, you should prac-
tice turning, stopping and backing up in an
area which is free from traffic. Steering,
stability, and braking performance are
somewhat different than under normal driv-
ing conditions.
cAlways secure items in the trailer to
prevent load shift while driving.
c
Avoid abrupt starts, acceleration or stops.
cAvoid sharp turns or lane changes.
cAlways drive your vehicle at a moderate
speed.
c
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if
you must do so, and if your vehicle is
equipped with automatic transmission,
first block the wheels and apply the park-
ing brake, and then move the transmis-
sion shift lever into the P position. If you
move the shift lever to the P position
before blocking the wheels and applying
the parking brake, transmission damage
could occur.

cWhen going down a hill, shift into a lower
gear and use the engine braking effect.
When ascending a long grade, down-
shift the transmission to a lower gear
and reduce speed to reduce chances of
engine overloading and/or overheating.
c
If the engine temperature coolant rises to
an extremely high temperature when the
air conditioning system is on, turn off the
air conditioner. Coolant heat can be addi-
tionally vented by opening the windows,
switching the fan control to high and set-
ting the temperature control to the HOT
position.
cTrailer towing requires more fuel than
normal circumstances.
cAvoid towing a trailer for your vehicle's
first 500 miles (800 km).
cHave your vehicle serviced more often
than at intervals specified in the recom-
mended Maintenance Schedule.
cWhen making a turn, your trailer wheels
will be closer to the inside of the turn
than your vehicle wheels. To compen-
sate for this, make a larger than normal
turning radius during the turn.cCrosswinds and rough roads adversely
affect vehicle/trailer handling, possibly
causing vehicle sway. When being
passed by larger vehicles, be prepared
for possible changes in crosswinds that
could affect vehicle handling. If swaying
does occur, firmly grip the steering
wheel, steer straight ahead, and imme-
diately (but gradually) reduce vehicle
speed. This combination helps to stabi-
lize the vehicle. Never increase speed.
cBe careful when passing other vehicles.
Passing while towing a trailer requires
considerably more distance than normal
passing. Remember the length of the
trailer must also pass the other vehicle
before you can safely change lanes.
cTo maintain engine braking efficiency
and electrical charging performance, do
not use fifth gear (manual transmission)
or overdrive (automatic transmission).
cAvoid holding the brake pedal down too
long or too frequently. This could cause
the brakes to overheat, resulting in re-
duced braking efficiency.
When towing a trailer, change the oil in
the transmission more frequently.
See the Maintenance Schedule.DOT Quality Grades: All passenger car tires
must conform to Federal Safety Require-
ments in addition to these grades.
Treadwear
Treadwear grade is a comparative rating
based on tire wear rate when tested under
controlled conditions on specified govern-
ment test courses. For example, a tire
graded 150 would wear one and a half
(1-1/2) times as well on the government
course as a tire graded 100. However,
relative tire performance depends on actual
driving conditions, and may vary signifi-
cantly from the norm due to variations in
driving habits, service practices and differ-
ences in road characteristics and climate.
Traction A, B and C
Traction grades are A (the highest), B and C.
They represent a tire's ability to stop on wet
pavement as measured under controlled con-
ditions, on specified government test sur-
faces of asphalt and concrete. A tire marked
with a C may have poor traction performance.
WARNING
The traction grade assigned to your
vehicle tires is based on straight line
