2. Start the engine.
- Check that the 4WD vehicle information display warning message turns off. If the warning message in the vehicle information display stays on, have the sys-
tem checked. It is recommended that you visit a NISSAN dealer for this service.
3. Apply the parking brake, depress the brake pedal and move the shif t lever to the N (Neutral) position.
4. With the brake pedal depressed, move the 4WD shif t switch to the desired mode.
- Be sure to wait until the transfer gear change completes before shif ting the shif t lever from the N (Neutral) position.
*2: While changing in and out of 4LO, the ignition switch must be in the ON position and the vehicle's engine must be running for a shif t to take place and for the
4WD shif t and 4LO position indicators to be operable. Otherwise, the shif t will not take place and no indicators will be on or flashing.
*3: Make sure the transfer 4LO position indicator turns on when you shif t the 4WD shif t 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.
5-108Starting and driving

The transfer case 4WD shif t switch is used
to select either 2WD or 4WD depending on
the driving conditions. There are three
types of drive modes available: 2WD, 4H and
4LO.
The 4WD shif t switch electronically controls
the transfer case operation. Rotate the
switch to move between each mode: 2WD,
4H and 4LO.
To change into or out of 4LO, the vehicle
MUST be stationary, move the shif t lever
to N (Neutral), and depress the brake
pedal. The switch must be pushed and
turned to select 4LO.
WARNING
• When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shif t in-
dicator is on and the Automatic
Transmission Park (ATP) warning
light goes off. Otherwise, the vehicle
could unexpectedly move even if the
A/T is in the P (Park) position. •
The 4LO indicator must stop blinking
and remain illuminated or turn off
before shif ting the transmission into
gear. If the shif t lever is shif ted from
the N (Neutral) position to any other
gear when the 4LO indicator is blink-
ing, the vehicle may move
unexpectedly.
CAUTION
• Never shif t the 4WD shif t switch be-
tween 4LO and 4H while driving.
• The 4H position provides greater
traction. Avoid excessive speed, as it
will cause increased fuel consump-
tion and higher oil temperatures, and
could damage drivetrain compo-
nents. Speeds over 62 mph (100
km/h) in 4H is not recommended.
• The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 mph
(50 km/h).
• When driving straight, shif t the 4WD
shif t switch to the 2WD or 4H posi-
tion. Do not move the 4WD shif t
switch when making a turn or
reversing. •
Do not shif t the 4WD shif t switch (be-
tween 2WD and 4H) while driving on
steep downhill grades. Use the en-
gine brake and low A/T gears (M1 or
M2) for engine braking.
• Do not operate the 4WD shif t switch
(between 2WD and 4H) with the rear
wheels spinning.
• Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. NISSAN recommends driv-
ing in the 2WD position under these
conditions.
• The 4WD transfer case may not be
shif ted between 4H and 4LO at low
ambient temperatures and the
transfer 4LO position indicator may
blink even when the 4WD shif t switch
is shif ted. Af ter driving for a while
you can change the 4WD transfer
case between 4H and 4LO.
When driving on rough roads,
• Set the 4WD shif t switch to 4H or 4LO.
• Drive carefully according to the road sur- face conditions.
Starting and driving5-109

–In the 4LO position, stop the ve-
hicle, move the automatic trans-
mission shif t lever to the N (Neu-
tral) position with the brake pedal
depressed, and shif t the 4WD shif t
switch to 2WD.
• If the warning message is still on af-
ter the above operation, have your
vehicle checked as soon as possible.
It is recommended that you visit a
NISSAN dealer for this service.
• The transfer case may be damaged if
you continue driving with the warn-
ing message on. The E-Lock system can provide additional
traction and should only be used when a
vehicle has become or is becoming stuck.
This system operates by electronically
“locking” the two rear drive wheels to-
gether, 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 ve-
hicles).
When added traction is required, activate
the E-Lock system by pushing the switch
on. For additional information, refer to
“Electronic locking rear differential (E-Lock)
system switch” in the “Instruments and
controls” section of this manual. Once the
system fully engages, the indicator 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 sys-
tem 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 Braking System (ABS) is dis-
abled and the ABS warning light illumi-
nates when the E-Lock system is on.WARNING
• Never 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 per-
sonal injury. Af ter using the E-Lock
system to free the vehicle, turn the
system off.
• Use the E-Lock system only in an
emergency when it is not possible to
free a stuck vehicle even when using
4LO. Never use the E-Lock system on
a slippery road surface such as snow
or ice surface. Using the E-Lock sys-
tem when driving in these road con-
ditions may cause unexpected
movement of the vehicle during en-
gine braking, accelerating or turning,
which may result in an accident and
serious personal injury.
• Observe the above warnings. Other-
wise, loss of normal steering control
may result. This may result in an ac-
cident and serious personal injury.
ELECTRONIC LOCKING REAR
DIFFERENTIAL (E-Lock) SYSTEM (if
so equipped)
5-112Starting and driving

The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
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 downshif t 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 downshif ting. Abrupt braking
or accelerating 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 lon-
ger 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 drums/rotors are replaced,
in order to assure the best braking perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
• The ABS is a sophisticated device, but
it cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces 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 ve-
hicle in front of you. Ultimately, the
driver is responsible for safety.
• Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the
specified size of tires on all four
wheels.
BRAKE SYSTEM
5-116Starting and driving

–When installing a spare tire, make
sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer in-
formation” section of this manual.
– For additional information, refer
to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The 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 slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate 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 dis-
tances.
Self-test feature
The Anti-lock Braking System (ABS) in-
cludes 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 mal-
function. If the computer senses a mal-
function, it switches the ABS off and illumi-
nates 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 ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
Normal operation
The Anti-lock Braking System (ABS) oper-
ates at speeds abov e3-6mph(5-10
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 pres-
sure. This action is similar to pumping the
brakes very quickly. You may feel a pulsa-
tion 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 op-
erating properly. However, the pulsation
may indicate that road conditions are haz-
ardous and extra care is required while
driving.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force
than a conventional brake booster even
with light pedal force.
