tions for properly fastening a seat belt
shown in the “Three-point seat belt with
retractor” earlier in this section.
7. When the ignition is turned to the ON posi-
tion, the passenger air bag status light may
or may not be illuminated, depending on the
size of the child and the type of booster seat
being used. See “NISSAN advanced air bag
system” later in this section.PRECAUTIONS ON
SUPPLEMENTAL RESTRAINT
SYSTEM
This Supplemental Restraint System (SRS) sec-
tion contains important information concerning
the driver and passenger supplemental front air
bags (NISSAN Advanced Air Bag System) ,
supplemental side air bags, curtain side-impact
and rollover air bags and pre-tensioner seat belts.
Supplemental front impact air bag system:
The NISSAN advanced air bag system can help
cushion the impact force to the head and chest of
the driver and front passenger in certain frontal
collisions.
Supplemental side-impact air bag system
(if so equipped):This system can help cushion
the impact force to the chest area of the driver
and front passenger in certain side impact colli-
sions. The supplemental side air bag is designed
to inflate on the side where the vehicle is im-
pacted.
Supplemental curtain side-impact and roll-
over air bag system (if so equipped):This
system can help cushion the impact force to the
head of occupants in front and rear outboard
seating positions in certain side impact or rollover
collisions. In a side impact, the curtain air bags
are designed to inflate on the side where thevehicle is impacted. In a rollover both curtain air
bags are designed to inflate and remain inflated
for a short time.
These supplemental restraint systems are de-
signed tosupplementthe crash protection pro-
vided by the seat belts and arenot a substitute
for them. Seat belts should always be correctly
worn and the occupant seated a suitable dis-
tance away from the steering wheel, instrument
panel and door finishers. See “Seat belts” earlier
in this section for instructions and precautions on
seat belt usage.
The supplemental air bags operate only
when the ignition switch is in the ON or
START position.
After turning the ignition key 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.

monitoring system” in the “Starting and driving”
section and “Tire pressure monitoring system” in
the “In case of emergency” section.
Tire pressure monitoring system malfunc-
tion:
If the tire pressure monitoring system is not func-
tioning properly, the low tire pressure warning
light will flash for approximately 1 minute when
the ignition switch is turned on. The light will
remain on after the 1 minute. Have the system
checked by a NISSAN dealer.
For additional information, see “Tire pressure
monitoring system” in the “Starting and driving”
section.
WARNING
cIf the light does not illuminate with the
ignition switch turned ON, have the ve-
hicle checked by a NISSAN dealer as
soon as possible.cIf the light illuminates while driving,
avoid sudden 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 injury. Check
the tire pressure for all four tires. Adjust
the tire pressure to the recommended
COLD tire pressure shown on the Tire
and Loading Information label to turn
the low tire pressure warning light OFF.
If the light still illuminates while driving
after adjusting the tire pressure, a tire
may be flat. If you have a flat tire, re-
place it with a spare tire as soon as
possible.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated and the tire pressure monitor-
ing system will not function. Contact
your NISSAN dealer as soon as pos-
sible for tire replacement and/or sys-
tem resetting.
CAUTION
cThe tire pressure monitoring system is
not a substitute for the regular tire pres-
sure check. Be sure to check the tire
pressure regularly.
cIf the vehicle is being driven at speeds
of less than 16 MPH (26 km/h) , the tire
pressure monitoring system may not
operate correctly.
cBe sure to install the specified size of
tires to the 4 wheels correctly.

CAUTION
cDo not use leaded gasoline. Deposits
from leaded gasoline will seriously re-
duce the three-way catalyst’s ability to
help reduce exhaust pollutants.
cKeep 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 driv-
ing if the engine misfires, or if notice-
able loss of performance or other un-
usual operating conditions are
detected. Have the vehicle inspected
promptly by a NISSAN dealer.
cAvoid driving with an extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
three-way catalyst.
cDo not race the engine while warming it
up.
cDo 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 in-
flated to the inflation pressure recommended by
the vehicle manufacturer on the vehicle placard
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 inflation
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 pressure telltale
when one or more of your tires is significantly
underinflated. Accordingly, when the low tire pres-
sure telltale illuminates, you should stop and check
your tires as soon as possible, and inflate them to
the proper pressure. Driving on a significantly un-
derinflated tire causes the tire to overheat and can
lead to tire failure. Underinflation also reduces fuel
efficiency 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 underinflation has not reached the level 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 mal-
function 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 mal-
function exists. When the malfunction indicator 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 alter-
nate tires or wheels on the vehicle that prevent
the TPMS from functioning properly. Always
check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Additional information:
cThis system does not monitor the tire pres-
sure of the spare tire.
cThe low tire pressure warning system will
activate only when the vehicle is driven at
speeds above 16 MPH (26 km/h) . Also, this
system may not detect a sudden drop in tire
pressure (for example a flat tire while driving) .

cLower your speed when encountering
strong crosswinds. With a higher center
of gravity, your NISSAN is more af-
fected by strong side winds. Slower
speeds ensure better vehicle control.
cDo not drive beyond the performance
capablity of the tires, even with 4WD
engaged.
cAccelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.
cIf at all possible, avoid sharp turning
maneuvers, particularly at high speeds.
Your NISSAN four-wheel drive vehicle
has a higher center of gravity than a
two-wheel drive vehicle. The vehicle is
not designed for cornering at the same
speeds as conventional two-wheel
drive vehicles. Failure to operate this
vehicle correctly could result in loss of
control and/or a rollover accident.
cAlways use tires of the same type, size,
brand, construction (bias, bias-belted,
or radial) , and tread pattern on all four
wheels. Install tire chains on the rear
wheels when driving on slippery roads
and drive carefully.cBe sure to check the brakes immedi-
ately after driving in mud or water. See
“Brake system” later in this section for
“Wet brakes”.
cAvoid parking your vehicle on steep
hills. If you get out of the vehicle and it
rolls forward, backward or sideways,
you could be injured.
cWhenever you drive off-road through
sand, mud or water as deep as the
wheel hub, more frequent maintenance
may be required. See “Periodic mainte-
nance” in the “NISSAN Service and
Maintenance Guide.”

This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
ANTI-LOCK BRAKE SYSTEM (ABS)
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 and
varies 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 the light comes on during the self-test or while
driving, take the vehicle to a NISSAN dealer for
repair.
WARNING
cThe anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces even with the anti-lock brake
system. Stopping distances may also
be longer on rough, gravel or snow cov-
ered roads, or if you are using tire
chains. Tire type and condition may also
affect braking effectiveness. Always
maintain a safe distance from the ve-
hicle in front of you. Ultimately, the re-
sponsibility for safety of self and others
rests in the hands of the driver.
cTire type and condition of tires may also
affect braking effectiveness.
cWhen replacing tires, install the speci-
fied size of tires on all four wheels.

cWhen installing a spare tire, make sure
it is the proper size and type as speci-
fied on the tire placard. For tire placard
location information, refer to “Tire plac-
ard” in the “Technical and consumer
information” section of this manual.
cRefer to “Wheels and tires” in the
“Maintenance and do-it-yourself” sec-
tion of this manual.cABLS is a form of traction control using
sensors from the Anti-lock Brake System
(ABS) to transfer power from a slipping drive
wheel to a wheel with more traction. The
ABLS system applies braking to the slipping
wheel, which helps redirect power to an-
other wheel.
cOn 4WD models the ABLS system operates
in both 4H and 4LO modes. On 2WD ve-
hicles, the ABLS system operates on the
drive axle only.
cThe ABLS system is always ON unless the
system detects brake pad overheating. If
high brake pad temperature is detected, it
will turn OFF, but normal brake function will
continue. ABLS will function even when the
VDC system (if so equipped) is turned OFF.
WARNING
The ABLS system provides increased trac-
tion, but will not prevent accidents due to
abrupt steering operation or by careless
driving or dangerous driving practices.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces, and always drive
carefully.When accelerating or driving on slippery sur-
faces, the tires may spin or slide. With the Vehicle
Dynamic Control (VDC) system, sensors detect
these movements and control the braking and
engine output to help improve vehicle stability.
cWhen the vehicle dynamic control (VDC)
system is operating, the SLIP indicator in the
instrument panel blinks.
cIf the 4WD transfer case is shifted into 4LO
the
indicator light will come on and
the VDC system will be turned off. See
“Transfer case shifting procedures” earlier in
this section.
cIf the SLIP indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. See
“Slip indicator light”, and “Vehicle dynamic
control (VDC) off indicator light” in the “In-
struments and controls” section.
If the battery is removed or discharged, the trac-
tion control system may be disabled and the
SLIPand
indicator lights will not turn off
after 2 seconds when the ignition switch is turned
to the ON position. Perform the following proce-
dure to reset the system:
cStart the engine and set the steering wheel
in the straight forward position.

The hill start assist system automatically keeps
the brakes applied to help prevent the vehicle
from rolling backwards in the time it takes the
driver to release the brake pedal and apply the
accelerator when the vehicle is stopped on a hill.
Hill start assist will operate automatically under
the following conditions:
cThe selector lever is shifted to a forward or
reverse gear.
cThe vehicle is stopped completely on a hill
by applying the brake.
The maximum holding time is 2 seconds. After 2
seconds the vehicle will begin to roll back and hill
start assist will stop operating completely.
Hill start assist will not operate when the selector
lever is shifted to N or P or on a flat and level road.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply de-
icer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the key
hole or use the remote keyless entry keyfob (if so
equipped) .
ANTI-FREEZE
In the winter when it is anticipated that the tem-
perature will drop below 32°F (0°C) , check the
anti-freeze to assure proper winter protection.
For details, see “Engine cooling system” in the
“Maintenance and do-it-yourself” section of this
manual.
BATTERY
If the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain maxi-
mum efficiency, the battery should be checked
regularly. For details, see “Battery” in the “Main-
tenance and do-it-yourself” section of this
manual.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.
For details, see “Changing engine coolant” in the
“Maintenance and do-it-yourself” section of this
manual.
TIRE EQUIPMENT
1. SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your ve-
hicle on snowy or icy roads, NISSAN recom-
mends the use of MUD & SNOW or ALL
SEASON TIRES on all four wheels. Please
consult a NISSAN dealer for the tire type,
size, speed rating and availability informa-
tion.
2. For additional traction on icy roads, studded
tires may be used. However, some U.S.
states and Canadian provinces prohibit their
use. Check local, state and provincial laws
before installing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.

3. Tire chains may be used.
Use of tire chains may be prohibited accord-
ing to location. Check the local laws before
installing tire chains. When installing tire
chains, make sure they are the proper size
for the tires on your vehicle and are installed
according to the chain manufacturer’s sug-
gestions.Use only SAE Class “S”
chains.Class “S” chains are used on ve-
hicles with restricted tire to vehicle clear-
ance. Vehicles that can use Class “S” chains
are designed to meet the minimum clear-
ances between the tire and the closest ve-
hicle suspension or body component re-
quired to accommodate the use of a winter
traction device (tire chains or cables) . The
minimum clearances are determined using
the factory equipped tire size. Other types
may damage your vehicle. Use chain ten-
sioners when recommended by the tire
chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must be
secured or removed to prevent the possibil-
ity of whipping action damage to the fenders
or underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.Never install tire chains on spare tires. Do
not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
cA scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
cA sturdy, flat board to be placed under the
jack to give it firm support.
cA shovel to dig the vehicle out of snowdrifts.
cExtra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
cWet ice (32°F, 0°C and freezing rain) ,
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have much less traction or “grip” under
these conditions. Try to avoid driving on
wet ice until the road is salted or
sanded.cWhatever the condition, drive with cau-
tion. Accelerate and slow down with
care. If accelerating or downshifting too
fast, the drive wheels will lose even
more traction.
cAllow more stopping distance under
these conditions. Braking should be
started sooner than on dry pavement.
cAllow greater following distances on
slippery roads.
cWatch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a patch of
ice is seen ahead, brake before reach-
ing it. Try not to brake while on the ice,
and avoid any sudden steering
maneuvers.
cDo not use the cruise control on slip-
pery roads.
cSnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
