WARNING
.For AWD equipped vehicles, do not
attempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with
the engine running. Doing so may
result in drivetrain damage or un-
expected vehicle movement which
could result in serious vehicle da-
mage or personal injury.
.Do not attempt to test an AWD
equipped vehicle on a 2-wheel dy-
namometer (such as the dynam-
ometers used by some states for
emissions testing) or similar equip-
ment even if the other two wheels
are raised off the ground. Make sure
that you inform the test facility
personnel that your vehicle is
equipped with AWD before it is
placed on a dynamometer. Using
the wrong test equipment may re-
sult in drivetrain damage or unex-
pected vehicle movement which
could result in serious vehicle da-
mage or personal injury.

*2: LOCK mode will change to AUTO mode
automatically when the vehicle has been
driven at a high speed. The AWD LOCK
indicator light turns off.
*3: LOCK mode will automatically be cancelled
when the ignition switch is turned to the OFF
position.
.If the AWD LOCK switch is operated while
accelerating or decelerating, or if the ignition
switch is turned off, you may feel a jolt. This
is normal.
.The oil temperature of power train parts will
increase if the vehicle is continuously
operated under conditions where the differ-
ence in rotation between the front and rear
wheels is large (wheel slip) , such as when
driving the vehicle on rough roads through
sand, mud or freeing a stuck vehicle. In
these cases, the AWD warning light blinks
rapidly and the AWD mode changes to
2WD to protect the powertrain parts. If you
stop driving with the engine idling and wait
until the warning light stops blinking, the
AWD returns to the AUTO mode.
WARNING
.When driving straight, shift the AWD
LOCK switch to AUTO. Do not oper-
ate the AWD LOCK switch when
making a turn or backing up.
.Do not operate the AWD LOCK
switch with the front wheel spin-
ning.
.Engine idling speed is high while
warming up the engine. Be espe-
cially careful when starting or driv-
ing on slippery surfaces.
.When turning the vehicle in LOCK
mode on paved roads, you may feel
a braking effect. This is a normal
condition of the AWD model.

If any malfunction occurs in the AWD system
while the engine is running, the warning light will
come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high powertrain oil temperature. The
driving mode may change to 2WD. AUTO mode
may change to LOCK mode before the warning
light blinks. If the warning light blinks rapidly
during operation, stop the vehicle with the
engine idling in a safe place immediately. Then
if the light turns off after a while, you can
continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds) . Pull
off the road in a safe area, and idle the engine.
Check that all tire sizes are the same, tire
pressure is correct and tires are not worn.
CAUTION
.If the warning light remains on after
the above operation, have your
vehicle checked by a NISSAN dealer
as soon as possible.
.If the warning light comes on while
driving there may be a malfunction
in the AWD system. Reduce the
vehicle speed and have your vehiclechecked by a NISSAN dealer as
soon as possible.
.The powertrain may be damaged if
you continue driving with the warn-
ing light blinking rapidly.
.Never drive on dry hard surface
roads in the LOCK mode, as this
will overload the powertrain and
may cause a serious malfunction.5-24

WARNING
.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.
.Safe parking procedures require
that both the parking brake be set
and the transmission placed into P
(Park) . Failure to do so could cause
the vehicle to move unexpectedly or
roll away and result in an accident.
Make sure the selector lever has
been pushed as far forward as it cango and cannot be moved without
depressing the foot brake pedal.
.Never leave the engine running
while the vehicle is unattended.
.Do not leave children unattended
inside the vehicle. They could un-
knowingly activate switches or con-
trols. Unattended children could
become involved in serious acci-
dents.
1. Firmly apply the parking brake.
2. Move the selector lever to the P (Park)
position.3. To help prevent the vehicle from rolling into
traffic when parked on an incline, it is a good
practice to turn the wheels as illustrated.
.HEADED DOWNHILL WITH CURB:
*1
Turn the wheels into the curb and move
the vehicle forward until the curb side
wheel gently touches the curb.
.HEADED UPHILL WITH CURB:
*2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
.HEADED UPHILL OR DOWNHILL, NO

WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakesThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help reduce brake wear and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING
.While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt brakingor accelerating could cause the
wheelstoskidandresultinan
accident.
.If the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.PARKING BRAKE BREAK-INBreak in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service manual and can be performed by a
NISSAN dealer.

ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
surfaces even with ABS. Stopping
distances may also be longer on
rough, gravel or snow covered
roads, or if you are using tire chains.
Alwaysmaintainasafedistance
from the vehicle in front of you.
Ultimately, the driver is responsible
for safety.
.Tire 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 theTire and Loading Information
label. See “TIRE AND LOADING
INFORMATION LABEL” in the “9.
Technical and consumer infor-
mation” section of this manual.
— For detailed information, see
“WHEELS AND TIRES” in the
“8. Maintenance and do-it-your-
self” 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
prevent 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
slippery surfaces.
Using the systemDepress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing somay result in increased stopping dis-
tances.
Self-test featureThe 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 malfunction, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates 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 operationThe ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h) . The speed varies according to
road conditions.
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or

feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.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.
.When the VDC system is operating, the
“SLIP” indicator in the instrument panel
blinks.
.If the “SLIP” indicator blinks, the road
conditions are slippery. Be sure to adjust
your speed and driving to these conditions.
Be sure to drive carefully. (See “Slip
indicator light” in the “2. Instruments and
controls” section, and “Vehicle Dynamic
Control (VDC) off indicator light” in the “2.
Instruments and controls” section.)
.Indicator light
If a malfunction occurs in the system, the
“SLIP” and “VDC OFF” indicator lights
illuminate in the instrument panel. As long
as these indicators are illuminated, the VDC
system function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) function to improve vehicle traction.
The ABLS system works when one of the driving
wheels is spinning on a slippery surface. The
ABLS system brakes the spinning wheel, which
distributes the driving power to the other drivewheel. If the vehicle is operated with the VDC
OFF switch pushed and the VDC system turned
off, all VDC systems will be turned off. The
ABLS system and ABS will still operate with the
VDC system off. If the ABLS system is activated,
the “SLIP” indicator will blink and you may hear a
clunk noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication of a
malfunction.
While the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise
or feel a vibration from under the hood. This is
normal and indicates that the VDC system is
working properly.
The VDC system 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 forward or backward. When the
self-test occurs, you may hear a “clunk” noise
and/or feel a pulsation in the brake pedal. This is
normal and is not an indication of a malfunction.
WARNING
.The VDC system is designed to help
improve driving stability but does
not prevent accidents due to abrupt
steering operation at high speeds or
due to careless or dangerous driv-
ing techniques. Reduce vehicle

speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
.Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars and bushings and
wheels are not NISSAN approved
or are extremely deteriorated the
VDC system may not operate prop-
erly. This could adversely affect
vehicle handling performance, and
the “VDC OFF” indicator or “SLIP”
indicator or both indicator lights
may illuminate.
.If brake related parts such as brake
pads, rotors and calipers are not
standard equipment or are extre-
mely deteriorated, the “VDC OFF”
indicator or “SLIP” indicator or both
indicator lights may illuminate.
.If engine related parts such as
muffler are not standard equipment
or are extremely deteriorated, the
“VDC OFF” indicator or “SLIP” in-
dicator or both indicator lights may
illuminate..When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the “VDC OFF”
indicator or “SLIP” indicator or both
indicator lights may illuminate. Do
not drive on these types of roads.
.When driving on unstable surfaces
such as a turntable, ferry, elevator
or ramp, the “VDC OFF” indicator or
“SLIP” indicator or both indicator
lights may illuminate. This is not a
malfunction. Restart the engine
after driving onto a stable surface.
.If wheels or tires other than those
recommended are used, the VDC
system may not operate properly
and “VDC OFF” indicator or “SLIP”
indicator or both indicator lights
may illuminate.
.The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.
FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
deicer 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.ANTI-FREEZEIn the winter when it is anticipated that the
outside temperature will drop below 328F(08C) ,
check the anti-freeze to assure proper winter
protection. For additional information, see “EN-
GINE COOLING SYSTEM” in the “8. Main-
tenance and do-it-yourself” section.BATTERYIf the battery is not fully charged during
extremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery should
be checked regularly. For additional information,
see “BATTERY” in the “8. Maintenance and do-
it-yourself” section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system, including the
engine block. Refill before operating the vehicle.

TIRE EQUIPMENTSUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate your vehicle on snowy or icy
roads, NISSAN recommends the use of MUD &
SNOW or ALL SEASON tires on all four wheels.
Consult a NISSAN dealer for the tire type, size,
speed rating and availability information.
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.
Tire chains may be used. For details, see “TIRE
CHAINS” in the “8. Maintenance and do-it-
yourself” section of this manual.All-Wheel Drive (AWD) modelIf you install snow tires, they must also be the
same size, brand, construction and tread pattern
on all four wheels.
SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:
.A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
.A sturdy, flat board to be placed under the
jack to give it firm support.
.A shovel to dig the vehicle out of snow-
drifts.
.Extra window washer fluid to refill the
reservoir tank.DRIVING ON SNOW OR ICE
WARNING
.Wet ice (328F, 08C 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.
.Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheelswill lose even more traction.
.Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
.Allow greater following distances
on slippery roads.
.Watch 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 reaching it. Try not to brake
while on the ice, and avoid any
sudden steering maneuvers.
.Do not use cruise control on slip-
pery roads.
.Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)Engine block heatersare available through
NISSAN dealers to assist in cold temperature
starting. The engine block heater should be
used when the outside temperature is 208F
(78C) or lower.
