When the vehicle is stuck,
cSet the 4WD shift switch to 4H or 4LO.
cUse the Electronic Locking Rear Differential
(E-Lock) system (if so equipped) . Turn the
switch ON while the vehicle is stationary and
apply the throttle to try to free the vehicle.
cIf it is difficult to free the vehicle, rock the
vehicle back and forth between reverse and
drive gears.
cIf the vehicle is stuck deep in mud, place
stones or wooden blocks under the tires.
Then try the recovery procedures above. Tire
chains may be effective.
CAUTION
cDo not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
cAvoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
4WD shift switch operations
cShift the 4WD shift switch to either the
2WD, 4H or 4LO position, depending on
driving conditions.
cIf the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the key switch is
turned off while in the 4H or 4LO, you
may feel a jolt. This is not abnormal.
cWhen the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the selector lever is shifted to N or
P. This occurs because the transfer
clutch is released and not because of a
malfunction.
CAUTION
cWhen driving straight, shift the 4WD
shift switch to the 2WD or 4H position.
Do not move the 4WD shift switch when
making a turn or reversing.
cDo not shift the 4WD shift switch while
driving on steep downhill grades. Use
the engine brake and low automatic
transmission gears (D1 or D2) for en-
gine braking.
cDo not operate the 4WD shift switch
with the rear wheels spinning.
cBefore placing the 4WD shift switch in
the 4H position from 2WD, ensure the
vehicle speed is less than 62.5 MPH
(100 km/h) . Failure to do so can dam-
age the 4WD system.
cNever shift the 4WD shift switch be-
tween 4LO and 4H while driving.

The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within 1 second after
turning the ignition switch to the ON position.
While the engine is running, the 4WD shift indi-
cator light will illuminate the position selected by
the 4WD shift switch.
cThe 4WD shift indicator light may blink
while shifting from one drive mode to
the other. When the shifting is com-
pleted, the 4WD shift indicator light
will come on.cIf the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
cIf the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the 4H position
at low ambient temperatures, the 2WD
mode may be being engaged due to
malfunctioning drive system. If the indi-
cator does not return to normal and the
4WD warning light comes on, have the
system checked by the nearest NISSAN
dealer.

If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.
If the 4WD warning light comes on, the 4WD
shift indicator light goes out.
A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
cIf the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by a NISSAN
dealer as soon as possible.
cShifting between 4H and 4LO is not
recommended when the 4WD warning

cWhen the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in 4H. Be especially
careful when driving. If corresponding
parts are malfunctioning, the 4WD
mode will not be engaged even if the
4WD shift switch is shifted.
cDo not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift
switch to 2WD.
– in the 4LO position, stop the vehicle,
move the automatic transmission
shift selector lever to the N position
with the brake pedal depressed, and
shift the 4WD shift switch to 2WD.
cIf the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.The E-Lock system can provide additional trac-
tion and should only be used when a vehicle has
become or is becoming stuck. This system oper-
ates by electronically “locking” the two rear drive
wheels together, allowing them to turn at the
same speed. The system is used when it is not
possible to free a stuck vehicle even when using
the 4LO position (4 wheel drive vehicles) .
When added traction is required, activate the
E-Lock system by pushing the switch ON. See
“Electronic Locking Rear Differential (E-Lock)
system switch” in the “Instruments and Controls”
section. Once the system fully engages, the indi-
cator light in the instrument panel will remain ON.
When the system is activated, both rear wheels
will engage, providing added traction.
The rear wheels may momentarily slip or move to
engage the system, and the system will only
engage up to approximately 4 MPH (7 km/h) .
Once the vehicle is free, the system should be
turned OFF and driving resumed.
The Anti-Lock Brake (ABS) system is disabled
and the ABS light illuminates when the E-Lock
system is ON. Also, the Vehicle Dynamic Control
(VDC) system is disabled and the VDC light
illuminates when the E-Lock system is ON.WARNING
cNever leave the E-Lock system ON
when driving on paved or hard-surfaced
roads. Turning the vehicle may result in
the rear wheels slipping and result in an
accident and personal injury. After us-
ing the E-Lock system to free the ve-
hicle, turn the system OFF.
cUse the E-Lock system only when free-
ing a stuck vehicle. Try the 4LO position
before using the E-Lock system. Never
use the E-Lock system on a slippery
road surface such as snow or ice sur-
face. Using the E-Lock system when
driving in these road conditions may
cause unexpected movement of the ve-
hicle during engine braking, accelerat-
ing or turning, which may result in an
accident and serious personal injury.

CAUTION
cAfter using the E-Lock system, turn the
switch OFF to prevent possible damage
to driveline components from extended
use.
cDo not drive the vehicle at speeds faster
than 12 mph (20 km/h) when the system
is engaged. Doing so could damage
drivetrain components.
cDo not turn on the E-lock system while
the tires are spinning. Doing so could
damage drivetrain components.
WARNING
cDo not stop or park the vehicle over
flammable materials such as dry grass,
waste paper or rags. They may ignite
and cause a fire.
cSafe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park) . Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and re-
sult in an accident. Make sure the shift
lever has been pushed as far forward as
it can go and cannot be moved without
depressing the foot brake pedal.cNever leave the engine running while
the vehicle is unattended.
cDo not leave children unattended inside
the vehicle. They could unknowingly ac-
tivate switches or controls. Unattended
children could become involved in seri-
ous accidents.
1. Firmly apply the parking brake.
2. Move the shift 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.

4. Turn the ignition key to the LOCK position
and remove the key.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, especially
in sharp turns and at low speeds.
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 brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The 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 stopping dis-
tance will be longer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will overheat the brakes, wear out the
brake 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
cWhile driving on a slippery surface, be
careful when braking, accelerating or
downshifting. Abrupt braking or accel-
erating could cause the wheels to skid
and result in an accident.
cIf 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 brakes
When 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 the brakes, drive the vehicle at a safe
speed while lightly pressing 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-in
Break-in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drum/rotors are replaced, in order to assure the
best brake performance.This procedure is described in the vehicle service
manual and can be performed by a NISSAN
dealer.
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.
Normal operation
The ABS operates at speeds above3-6MPH(5
- 10 km/h) .
When the ABS senses that one or more wheels
are close to locking up, the system electronically
controls the pressure applied to each brake.
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 oper-
ating. This is normal and indicates that the ABS is
operating properly. However, the pulsation may
indicate that road conditions are hazardous and
extra care is required while driving.
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 brakepedal. 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.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. If 4WD mode is
engaged, the ABLS system will operate for
both drive axles. On 2WD vehicles, 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 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.
cIndicator light
– If a malfunction occurs in the system, the
SLIPand
indicator lights come on
in the instrument panel.
– If 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.
– As long as these indicator lights are on,
the traction control function is canceled.If the vehicle is operated with the Vehicle Dy-
namic Control system off using the VDC OFF
switch, most VDC functions will be turned off.
The VDC system will still try to transfer power
from a slipping drive wheel to one with more
traction when the VDC system switch is OFF. The
SLIPindicator will flash if wheel spin is detected.
The ABS will still operate with the VDC system
off.
When the VDC system is operating, you may feel
a pulsation in the brake pedal and hear a noise or
vibration from under the hood. This is normal and
indicates that the VDC system is working prop-
erly.
The computer has a built in diagnostic feature
that tests the system each time you start the
engine and move the vehicle forward or in reverse
at a slow speed. 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
cThe Vehicle Dynamic Control system is
designed to help improve driving stabil-
ity but does not prevent accidents due
to abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful when
driving and cornering on slippery sur-
faces and always drive carefully.
cIf brake related parts such as brake
pads, rotors and calipers are not stan-
dard equipment or are extremely dete-
riorated, the Vehicle Dynamic Control
system may not operate properly and
the Vehicle Dynamic Control off indica-
tor light may come on.
cDo not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
approved for your vehicle or are ex-
tremely deteriorated the Vehicle Dy-
namic Control system may not operate
properly. This could adversely affect ve-
hicle handling performance, and the
VDC OFF indicator light may come on.

cWhen driving on extremely inclined sur-
faces such as higher banked corners,
the Vehicle Dynamic Control system
may not operate properly and the VDC
OFF indicator light may come on. Do
not drive on these types of roads.
cWhen driving on an unstable surface
such as a turntable, ferry, elevator or

not a malfunction. Restart the engine
after driving onto a stable surface.
cIf wheels or tires other than the recom-
mended ones are used, the Vehicle Dy-

properly and the Vehicle Dynamic Con-
trol off indicator light may come on.
cThe Vehicle Dynamic Control system is
not a substitute for winter tires or tire
chains on a snow covered road.
WARNING
cAlways turn and look back before back-
ing up. The RSS is not a substitute for
proper backing procedures.
cRead and understand the limitations of
the rear sonar system as contained in
this section. Inclement weather may af-
fect the function of the RSS; this may
include reduced performance or a false
activation.
cThis system is not designed to prevent
contact with small or moving objects.cThe system is designed as an aid to the
driver in detecting large stationary ob-
jects to help avoid damaging the ve-
hicle. The system will not detect small
objects below the bumper, and may not
detect objects close to the bumper or
on the ground.
cIf your vehicle sustains damage to the
rear bumper fascia, leaving it mis-
aligned or bent, the sensing zone may
be altered causing inaccurate measure-
ment of obstacles or false alarms.
The Rear Sonar System (RSS) sounds a tone to
warn the driver of obstacles near the rear bumper
when the shift selector is in R (Reverse) . The
system may not detect objects at speeds above 3
mph (5 km/h) and may not detect certain angular
or moving objects.
The RSS detects obstacles up to 6 feet (1.8 m)
from the rear bumper with a decreased coverage
area at the outer corners of the bumper, (refer to
the illustration for approximate zone coverage
areas) . As you move closer to the obstacle, the
rate of the tone increases. When the obstacle is
less than 10 inches (25.0 cm) away, the tone will
sound continuously. If the RSS detects a station-
ary or receding object further than 10 inches
(25.0 cm) from the side of the vehicle, the tone

will sound for only three seconds. Once the sys-
tem detects an object approaching, the tone will
sound again.
The RSS automatically turns on when the shift
selector lever is placed in R (Reverse) and the
ignition is ON. The RSS OFF switch on the
instrument panel allows the driver to turn the RSS
on and off. To turn the RSS off, the ignition must
be ON, and the shift selector lever in R (Reverse) .
An indicator light on the switch will illuminate
when the system is turned off. If the indicator light
illuminates when the RSS is not turned off, it may
indicate a failure in the RSS.
Keep the RSS sensors (located on the rear
bumper fascia) free from snow, ice and large
accumulations of dirt (do not clean the sensors
with sharp objects) . If the sensors are covered, it
will affect the accuracy of the RSS.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.
