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 pres-
sure gauge to check the tire pressure.
For additional information, see “Tire Pressure
Monitoring System (TPMS)” in the “Starting and
driving” section and in the “In case of emergency”
section.
TPMS malfunction:
If the TPMS is not functioning properly, the low
tire pressure warning light will flash for approxi-
mately 1 minute when the ignition switch is
placed in the ON position. 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 (TPMS)” in the “Starting and
driving” section and “Tire pressure” in the “Main-
tenance and do-it-yourself” section.
WARNING
cIf the light does not illuminate with the
ignition switch placed in the ON posi-
tion, have the vehicle 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.
Driving with under-inflated tires may
permanently damage the tires and in-
crease the likelihood of tire failure. Se-
rious vehicle damage could occur and
may lead to an accident and could re-
sult 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 located
in the driver’s door opening 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 in-
dicated, the TPMS will not function and
the low tire pressure warning light will
flash for approximately 1 minute. The
light will remain on after 1 minute. Con-
tact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.
CAUTION
cThe TPMS is not a substitute for the
regular tire pressure check. Be sure to
check the tire pressure regularly.
cIf the vehicle is being driven at speeds
of less than 16 MPH (25 km/h) , the
TPMS may not operate correctly.
cBe sure to install the specified size of
tires to the 4 wheels correctly.

cDo not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.
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.”WARNING
cNever remove or turn the key to the
LOCK position while driving. The steer-
ing wheel will lock. This may cause the
driver to lose control of the vehicle and
could result in serious vehicle damage
or personal injury.
cNever turn the ignition switch to the
LOCK position while driving. The steer-
ing wheel will lock. This may cause the
driver to lose control of the vehicle and
could result in serious vehicle damage
or personal injury

ANTI-LOCK BRAKING SYSTEM
(ABS)
WARNING
cThe Anti-lock Braking System (ABS) is a
sophisticated device, but it cannot pre-
vent accidents resulting from careless
or dangerous driving techniques. It can
help maintain vehicle control during
braking on slippery surfaces. Remem-
ber that stopping distances on slippery
surfaces will be longer than on normal
surfaces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain a
safe distance from the vehicle in front
of you. Ultimately, the driver is respon-
sible for safety.
cTire type and condition may also affect
braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.– When installing a spare tire, make
sure that it is the proper size and type
as specified on the Tire and Loading
Information label. See “Tire and
Loading Information label” in the
“Technical and consumer informa-
tion” section of this manual.
– For detailed information, see
“Wheels and tires” in the “Mainte-
nance and do-it-yourself” section of
this manual.
The Anti-lock Braking System (ABS) controls the
brakes so the wheels do not lock during hard
braking or when braking on slippery surfaces.
The system detects the rotation speed at each
wheel and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding. By
preventing each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on slip-
pery surfaces.
Using the system
Depress the brake pedal and hold it down. De-
press the brake pedal with firm steady pressure,
but do not pump the brakes. The ABS will oper-
ate to prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and 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 pulsation in the brake
pedal. This is normal and does not indicate a
malfunction. If the computer senses a malfunc-
tion, it switches the ABS off and illuminates the
ABS warning light on the instrument panel. The
brake system then operates normally, but without
anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .

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. For details see
“Tire chains” in the “Maintenance and do-it-
yourself” section of this manual.
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.

TIRE LABELING
Federal law requires tire manufacturers to
place standardized information on the
sidewall of all tires. This information iden-
tifies and describes the fundamental
characteristics of the tire and also pro-
vides the tire identification number (TIN)
for safety standard certification. The TIN
can be used to identify the tire in case of a
recall.
s1Tire size (example: P215/65R15 95H)
1. P: The “P” indicates the tire is de-
signed for passenger vehicles (not all
tires have this information) .
2. Three-digit number (215): This num-
ber gives the width in millimeters of
the tire from sidewall edge to side-
wall edge.
3. Two-digit number (65): This number,
known as the aspect ratio, gives the
tire’s ratio of height to width.4. R: The “R” stands for radial.
5. Two-digit number (15): This number
is the wheel or rim diameter in inches.
6. Two- or three-digit number (95): This
number is the tire’s load index. It is a
measurement of how much weight
each tire can support. You may not
find this information on all tires be-
cause it is not required by law.

Summer tires
NISSAN specifies summer tires on some models
to provide superior performance on dry roads.
Summer tire performance is substantially re-
duced in snow and ice. Summer tires do not have
the tire traction rating “M&S” on the tire sidewall.
If you plan to operate your vehicle in snowy or icy
conditions, NISSAN recommends the use of
SNOW tires or ALL SEASON tires on all four
wheels.
Snow tires
If snow tires are needed, it is necessary to select
tires equivalent in size and load rating to the
original equipment tires. If you do not, it can
adversely affect the safety and handling of your
vehicle.
Generally, snow tires have lower speed ratings
than factory equipped tires and may not match
the potential maximum vehicle speed. Never ex-
ceed the maximum speed rating of the tire.
If you install snow tires, they must be the same
size, brand, construction and tread pattern on all
four wheels.
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 installingstudded tires. Skid and traction capabilities of
studded snow tires on wet or dry surfaces may be
poorer than that of non-studded snow tires.
TIRE CHAINS
Use of tire chains may be prohibited according 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 suggestions.Use only SAE
class “S” chains.Class “S” chains are used on
vehicles with restricted tire to vehicle clearance.
Vehicles that can use Class “S” chains are de-
signed to meet the minimum clearances between
the tire and the closest vehicle suspension or
body component required 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 tensioners
when recommended by the tire chain manufac-
turer to ensure a tight fit. Loose end links of the
tire chain must be secured or removed to prevent
the possibility of whipping action damage to the
fenders or underbody. If possible, avoid fully load-
ing 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.Tire chains must be installed only on the
rear wheels and not on the front wheels.
Do not use tire chains on dry roads. Driving with
chains in such conditions can cause damage to
the various mechanisms of the vehicle due to
some overstress.
Use only the 2WD range when driving on clear
paved roads.

cThe original tires have built-in
tread wear indicators. When the
wear indicators are visible, the
tire(s) should be replaced.
cTires degrade with age and use.
Have tires, including the spare,
over 6 years old checked by a
qualified technician because
some tire damage may not be ob-
vious. Replace the tires as neces-
sary to prevent tire failure and
possible personal injury.
cImproper service of the spare tire
may result in serious personal in-
jury. If it is necessary to repair the
spare tire, contact a NISSAN
dealer.
cFor additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information”
(Canada) in the Warranty Infor-
mation Booklet.Replacing wheels and tires
When replacing a tire, use the same size, tread
design, speed rating and load carrying capacity
as originally equipped. Recommended types and
sizes are shown in “Wheels and tires” in the
“Technical and consumer information” section of
this manual.
WARNING
cThe use of tires other than those recom-
mended 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, VDC system, ground clear-
ance, body-to-tire clearance, tire chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to acci-
dents and could result in serious per-
sonal injury.
cIf your vehicle was originally equipped
with 4 tires that were the same size and
you are only replacing 2 of the 4 tires,
install the new tires on the rear axle.
Placing new tires on the front axle may
cause loss of vehicle control in some
driving conditions and cause an acci-
dent and personal injury.cIf the wheels are changed for any rea-
son, always replace with wheels which
have the same off-set dimension.
Wheels of a different off-set could
cause premature tire wear, degrade ve-
hicle handling characteristics, affect
the VDC system and/or interference
with the brake discs/drums. Such inter-
ference can lead to decreased braking
efficiency and/or early brake pad/shoe
wear. Refer to “Wheels and tires” in the
“Technical and consumer information”
section of this manual for wheel off-set
dimensions.
cWhen a spare tire is mounted or a wheel
is replaced, tire pressure will not be
indicated, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your NISSAN dealer as soon as
possible for tire replacement and/or
system resetting.
cReplacing tires with those not originally
specified by NISSAN could affect the
proper operation of the TPMS.

cDo not install a damaged or deformed
wheel or tire even if it has been re-
paired. Such wheels or tires could have
structural damage and could fail with-
out warning.
cThe use of retread tires is not
recommended.
cFor additional information regarding
tires, refer to “Important Tire Safety In-
formation” (US) or “Tire Safety Informa-
tion” (Canada) in the Warranty Informa-
tion Booklet.
Four-wheel drive models
CAUTION
Always use tires of the same type, size,
brand, construction (bias, bias-belted or
radial) , and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.If excessive tire wear is found, it is recommended
that all four tires be replaced with tires of the
same size, brand, construction and tread pattern.
The tire pressure and wheel alignment should
also be checked and corrected as necessary.
Contact a NISSAN dealer.
Wheel balance
Unbalanced wheels may affect vehicle handling
and tire life. Even with regular use, wheels can get
out of balance. Therefore, they should be bal-
anced as required.
Wheel balance service should be per-
formed with the wheels off the vehicle.
Spin balancing the wheels on the vehicle
could lead to mechanical damage.
cFor additional information regarding
tires, refer to “Important Tire Safety
Information” (US) or “Tire Safety Infor-
mation” (Canada) in the Warranty In-
formation Booklet.
Care of wheels
cWash the wheels when washing the vehicle
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.
