5-24Starting and driving

*1: The transfer 4LO position indicator light may blink. Stop the vehicle. Be sure to shift the 4WD shift switch after the shift lever has been moved to theN
position. If the indicator light keeps blinking after the 4WD shift procedure in the previous page, drive slowly without abrupt maneuvers for a while. Then the
light will turn on or off.
• Avoid making a turn or abrupt starts while shifting to 4LO. Otherwise gears may grind, damaging the drive system.
*2: While changing in and out of 4LO, the ignition switch must be ON and the vehicle’s engine must be running for a shift to take place and for the indicator
lights (4WD shift and 4LO position indicator) to be operable. Otherwise, the shift will not take place and no indicator lights will be on or flashing.
*3: Make sure the transfer 4LO position indicator light turns on when you shift the 4WD shift switch to 4LO. The
indicator light will also turn on when
4LO is selected. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.
The transfer case 4WD shift switch is used to select either 2WD or 4WD depending on the driving conditions. There are four types of drive modes available,
AUTO, 2WD, 4H and 4LO.
Starting and driving5-25

The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
shift lever in the N position when changing
into or out of 4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage drivetrain components, Speeds
over 62 MPH (100 km/h) in 4H is not
recommended. ●
The 4LO position provides maximum
power and traction. Avoid raising vehicle
speed excessively, as the maximum speed
is approximately 31 MPH (50 km/h).
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
●
Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the engine
brake and low automatic transmission
gears (D1 or D2) for engine braking.
● Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
●
Do not drive on dry hard surface roads in
the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear. NISSAN
recommends driving in the 2WD or AUTO
position under these conditions.
●The 4WD transfer case may not be shifted
between 4H and 4LO at low ambient tem-
peratures and the transfer 4LO position
indicator light may blink even when the
4WD shift switch is shifted. After driving
for a while you can change the 4WD
transfer case between 4H and 4LO.
When driving on rough roads,
● Set the 4WD shift switch to AUTO, 4H or
4LO.
● Drive carefully according to the road surface
conditions.
When the vehicle is stuck, ● Set the 4WD shift switch to 4H or 4LO.
● If it is difficult to free the vehicle, repeat
forward and backward movement to in-
crease the movement.
● If 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
● Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
● Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
5-26Starting and driving

4WD shift switch operations
●Shift the 4WD shift switch to either the
2WD, AUTO, 4H or 4LO position, depend-
ing on driving conditions.
● With the switch set to the AUTO position,
distribution of torque to the front and rear
wheels changes automatically, depending
on road conditions encountered [ratio; 0 :
100 (2WD) →50 : 50 (4WD)]. This results
in improved driving stability. ●
If the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the ignition switch is
turned off while in the AUTO, 4H or
4LO, you may feel a jolt. This is not
abnormal.
● When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the shift lever is shifted to N or P.
This occurs because the transfer clutch
is released and not because of a mal-
function.
CAUTION
● When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
● Do 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.
● Do not operate the 4WD shift switch
with the rear wheels spinning. ●
Before placing the 4WD shift switch in
the 4H position from 2WD or AUTO,
ensure the vehicle speed is less than
62 MPH (100 km/h). Failure to do so can
damage the 4WD system.
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● Engine idling speed is high while warm-
ing up the engine. Be especially careful
when starting or driving on slippery sur-
faces with the 4WD shift switch set in
AUTO.

4WD shift indicator light
The 4WD shift indicator light is located in the
vehicle information display.
The light should turn off within one 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.●
The 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. If the indicator light does not
come on immediately, make sure the
area around the vehicle is safe, and
drive the vehicle straight, accelerate or
decelerate or move the vehicle in re-
verse, then shift the 4WD shift switch.
● If the 4WD warning light comes on, the
4WD indicator light goes out.
CAUTION
● When the 4WD shift switch is turned to
the AUTO position at low ambient tem-
peratures, the 4WD shift indicator light
may show 4H. If this happens, all four
wheels are driven as torque distribution
is in the 4H position. Be careful as the
vehicle may become difficult to turn.
When the vehicle is driven, the 4WD
shift indicator light should change to
AUTO. ●
If the 4WD shift indicator light indica-
tion changes to 2WD when the 4WD
shift switch is shifted to the AUTO or 4H
position at low ambient temperatures,
the 2WD mode may be being engaged
due to malfunctioning drive system. If
the indicator does not return to normal
and the 4WD warning light comes on,
have the system checked by the nearest
NISSAN dealer.

5-28Starting and driving

The 4WD warning light comes on when the igni-
tion switch is turned to ON. It turns off soon after
the engine is started.
If any malfunction occurs in the 4WD system
when the ignition 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.
High-temperature transfer case oil makes the
warning light blink rapidly (about twice per sec-
ond) . If the warning light blinks rapidly during
operation, stop the vehicle in a safe place imme-
diately. Then if the light goes 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) . Change
the 4WD shift switch into 2WD and do not drive
fast.
CAUTION
●If 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. ●
Shifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.
● When the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in AUTO or 4H. Be
especially careful when driving. If corre-
sponding parts are malfunctioning, the
4WD mode will not be engaged even if
the 4WD shift switch is shifted.
● Do 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 AUTO or 4H position, shift the 4WD shift switch to 2WD.
– in the 4LO position, stop the vehicle, move the shift lever to the N position
with the brake pedal depressed, and
shift the 4WD shift switch to 2WD. ●
If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
● The transfer case may be damaged if
you continue driving with the warning
light blinking.
Starting and driving5-29

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) . 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. ●
Never leave the engine running while
the vehicle is unattended.
● To help avoid risk of injury or death
through unintended operation of the
vehicle and/or its systems, do not leave
children, people who require the assis-
tance of others or pets unattended in
your vehicle. Additionally, the tempera-
ture inside a closed vehicle on a warm
day can quickly become high enough to
cause a significant risk of injury or
death to people and pets.
1. Firmly apply the parking brake.
2. Move the shift 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:
A
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
B
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
CURB:
C
Turn the wheels toward the side of the road
so the vehicle will move away from the cen-
ter of the road if it moves.
4. Place the ignition switch in the LOCK posi- tion.

PARKING/PARKING ON HILLS
5-30Starting and driving

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
●
While 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. ●
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 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
effect of the parking brake is weakened or when-
ever 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. It is recommended you visit a NISSAN
dealer for this service.
