5-128Starting and driving
The 4WD shift switch is used to select the
4WD mode depending on the driving
conditions. There are 3 types of drive
modes available, AUTO, 4HI and 4LO.
The 4WD shift switch electronically con-
trols the transfer case operation. Rotate
the switch to move between each mode,
AUTO, 4H and 4L.
You must depress the 4WD shift switch
to select 4L, and the vehicle MUST be
stationary and the shift lever in the N
(Neutral) position when changing into
or out of 4L.
WARNING
.When parking, apply the parking
brake before stopping the engine
and make sure that the 4WD shift
indicator is on and the ATP warn-
ing light turns off. Otherwise, the
vehicle could unexpectedly move
even if the automatic transmis-
sion is in the P (Park) position.
. The 4LO and 4HI indicators must
stop blinking and the 4LO or 4HI
indicator must remain illumi-
nated or turn off before shifting
the transmission into gear. If the
shift lever is shifted from the N
(Neutral) position to any other gear while the 4LO and 4HI in-
dicators are blinking alternately,
the vehicle may move unexpect-
edly.
CAUTION
.
Never shift the 4WD shift switch
between 4L and 4H while driving.
. The 4HI position provides greater
traction. Avoid excessive speed,
as it will cause increased fuel
consumption and higher oil tem-
peratures, and could damage dri-
vetrain component. Speeds over
62 MPH (100 km/h) in 4HI is not
recommended.
. The 4LO position provides max-
imum traction. Avoid raising ve-
hicle speed excessively, as the
maximum speed is approxi-
mately 31 MPH (50 km/h).
. When driving straight, shift the
4WD shift switch to the AUTO or
4H position. Do not move the 4WD
shift switch when making a turn
or reversing.
. Do not shift the 4WD shift switch
(between AUTO and 4H) while
driving on steep downhill grades. Use the engine brake and low
automatic transmission gears
for engine braking.
. Do not operate the 4WD shift
switch (between AUTO and 4H)
with the rear wheels spinning.
. Do not drive on dry hard surface
roads in the 4HI or 4LO position.
Driving on dry hard surfaces in
4HI or 4LO may cause unneces-
sary noise and tire wear. NISSAN
recommends driving in the AUTO
position under these conditions.
. The 4WD transfer case may not
be shifted between 4HI and 4LO
at low ambient temperatures and
the 4LO and 4HI indicators may
blink even when the 4WD shift
switch is shifted. After driving for
a while you can change the 4WD
shift switch between 4H and 4L.
When driving on rough roads,
. Drive carefully according to the road
surface conditions.
When the vehicle is stuck,
. Place stones or wooden blocks under
the tires to free the vehicle.
. Set the 4WD shift switch to 4H or 4L.

— When driving on a steep hill.
SYSTEM TEMPORARILY UNAVAIL-
ABLE
When sonar blockage is detected, the
system will be deactivated automatically.
The system is not available until the
conditions no longer exist.
The sonar sensors may be blocked by
temporary ambient conditions such as
splashing water, mist or fog. The blocked
condition may also be caused by objects
such as ice, frost or dirt obstructing the
sonar sensors.
Action to take:
When the above conditions no longer
exist, the system will resume automati-
cally.
SYSTEM MAINTENANCE
The sonar sensors are located on the
front and rear bumpers. (See “Exterior
front” (P.0-3) and “Exterior rear” (P.0-4).)
.Always keep the area near the sonar
sensors clean.
. If the sonar sensors are dirty, wipe
them off with a soft cloth while being
careful to not damage them.
. The sonar sensors may be blocked by
temporary ambient conditions such as splashing water, mist or fog. The
blocked condition may also be caused
by objects such as ice, frost or dirt
obstructing the sonar sensors. Check
for and remove objects obstructing
the area around the sonar sensors.
. Do not subject the area around the
sonar sensors to strong impact. Also,
do not remove or disassemble the
sonar sensors. If the sonar sensors
and peripheral areas are deformed in
an accident, etc., have the sonar
sensors checked by a NISSAN dealer.
. Do not attach stickers (including
transparent material), install acces-
sories or apply additional paint on
the sonar sensors and their surround-
ing areas. This may cause a malfunc-
tion or improper operation.
. When washing the vehicle using a
high-pressure washer, do not apply
direct washer pressure on the sonar
sensors. This may cause a malfunction
of the sonar sensors.
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 hy-
draulic 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.

POWER STEERING

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.
WARNING
The Brake Assist is only an aid to
assist braking operation and is not a
collision warning or avoidance de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
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 dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces even with ABS. Stopping
distances 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
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
the Tire and Loading Informa-
tion label. See “Tire and load-
ing information label” (P.10-
13).
— For detailed information, see “Wheels and tires” (P.8-28).
The Anti-lock Braking System (ABS) con-
trols 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 pre-
venting 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 ABS 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
distances.
Self-test feature
The ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-
tion, it switches the ABS off and
Starting and driving5-143
BRAKE ASSIST

5-144Starting and driving
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. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The 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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following: .
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. 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 properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn
off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the OFF
position then back to the ON position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the
Vehicle Dynamic Control (VDC) system ON
for most driving conditions.
When the vehicle is stuck in mud or snow,
the VDC system reduces the engine out-
put to reduce wheel spin. The engine
speed will be reduced even if the accel-
erator is depressed to the floor. If max-
imum engine power is needed to free a
stuck vehicle, turn the VDC system off.
To turn off the Vehicle Dynamic Control
(VDC) system, push the VDC OFF switch.
The VDC off indicator light
will
illuminate. Push the VDC OFF switch again or restart
the engine to turn ON the system.
FREEING A FROZEN DOOR LOCK
To 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
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that
the outside temperature will drop below
32°F (0°C), check antifreeze to assure
proper winter protection. For additional
information, see “Engine cooling system”
(P.8-4).
BATTERY
If 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”
(P.8-11).
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“Engine cooling system” (P.8-4).
COLD WEATHER DRIVING

cold temperature starting.
The engine block heater should be used
when the outside temperature is 20°F
(−7°C) or lower.
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the en-gine block heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged exten-
sion cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected,
grounded 110-volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours,
depending on outside temperatures,
to properly warm the engine coolant.
Use an appropriate timer to turn the
engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it
away from moving parts.
WARNING
.Do not use your engine block
heater with an ungrounded elec-
trical system or a 2-pronged
adapter. You can be seriously
injured by an electrical shock if
you use an ungrounded connec-
tion.
. Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to
the cord could result in an elec-
trical shock and can cause ser-
ious injury.
. Use a heavy-duty 3-wire, 3-
pronged extension cord rated
for at least 10A. Plug the exten-
sion cord into a Ground Fault
Interrupt (GFI) protected,
grounded 110-VAC outlet. Failure
to use the proper extension cord
or a grounded outlet can result in
a fire or electrical shock and
cause serious personal injury.
