IlluminatedFor use when maximum power and traction is
required (for example: on steep grades or rocky,
sandy, muddy roads)
*1: Before moving the transmission selector or shift lever from neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedure is completed and the transfer gear is correctly set in
the 4LO position. If the vehicle is shifted into gear before the indicator is on steady, the transfer gear may grind, not engage correctly or stay in the neutral position.
- If the 4WD warning light illuminates, perform the following procedure to return the transfer case to correct operating condition.
1. Turn off the engine by turning the ignition switch9OFF9.
2. Start the engine.
- Check that the 4WD warning light turns off. If the 4WD warning light illuminates, have the system checked by a NISSAN dealer.
3. Apply the parking brake, for automatic transmission vehicles, depress the brake pedal and move the transmission selector to Neutral position. Formanual transmission vehicles, move the transmission shift lever to
Neutral position.
4. With the brake pedal depressed on automatic transmission vehicles or with the clutch pedal depressed on manual transmission vehicles, move the 4WDshift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the transmission selector or transmission shift lever from Neutral position.
*2: While changing in and out of 4LO, the ignition key 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 (if so equipped) will also turn on when 4LO is selected. See “Vehicle dynamic control
system” later in this section.

The 4WD shift indicator light is located in the
odometer 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
If the 4WD shift indicator light indication
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 malfunc-
tioning 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.

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) for
automatic transmission models or in an
appropriate gear for manual transmis-
sion models. Failure to do so could
cause the vehicle to move unexpectedly
or roll away and result 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.Manual transmission models:
Place the shift lever in the R (Reverse) posi-
tion. When parking on an uphill grade, place
the shift lever in 1st gear.
Automatic transmission models:
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.
cHEADED DOWNHILL WITH CURB:
sA
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
cHEADED UPHILL WITH CURB:
sB
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
cHEADED UPHILL OR DOWNHILL, NO
CURB:
sC
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. Turn the ignition key to the LOCK position
and remove the key.

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 actuator rapidly ap-
plies 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 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.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 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.
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.
If the battery is removed or discharged, the trac-
tion control system may be disabled and the
SLIPand
indicator lights will not turn off
after 2 seconds when the ignition switch is turned
to the ON position. Perform the following proce-
dure to reset the system:
cStart the engine and set the steering wheel
in the straight forward position.

cDrive the vehicle at speeds above 10 mph
(15 km/h) for at least 10 minutes.
cThe VDC OFF indicator light should go off
indicating the traction control system is op-
erational.
cIf you interrupt the reset procedure by turn-
ing the ignition off, you will need to restart
the reset procedure.
If after driving the vehicle for more than 10 min-
utes and theSLIPand
lights remain illumi-
nated in the instrument panel, have the vehicle
dynamic control system checked by a NISSAN
dealer.
If the vehicle is operated with the vehicle dynamic
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 slip-
ping drive wheel to one with more traction when
the VDC system switch is OFF. The Slip indicator
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 theengine 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
and bushings are not NISSAN approved
for your vehicle or are extremely dete-
riorated the vehicle dynamic controlsystem may not operate properly. This
could adversely affect vehicle handling
performance, and the VDC OFF indica-
tor 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
ramp, the vehicle dynamic control off
indicator light may illuminate. This is
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-
namic control system may not operate
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.

When performing any inspection or maintenance
work on your vehicle, always take care to prevent
serious accidental injury to yourself or damage to
the vehicle. The following are general precau-
tions which should be closely observed.
WARNING
cPark the vehicle on a level surface, ap-
ply the parking brake securely and
block the wheels to prevent the vehicle
from moving. Move the shift selector
lever to P (Park) .
cBe sure the ignition key is in the OFF or
LOCK position when performing any
parts replacement or repairs.
cNever leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
cNever connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
c
Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and the
engine is not running. To avoid injury,
always disconnect the negative battery
cable before working near the fan.
cIf you must work with the engine run-
ning, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts.
cIt is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
cAlways wear eye protection whenever
you work on your vehicle.
cIf you must run the engine in an en-
closed space such as a garage, be sure
there is proper ventilation for exhaust
gases to escape.
cNever get under the vehicle while it is
supported only by a jack. If it is neces-
sary to work under the vehicle, support
it with safety stands.
cKeep smoking materials, flame and
sparks away from the fuel tank and
battery.
cOn gasoline engine models with the
multiport fuel injection (MFI) system,
the fuel filter or fuel lines should be
serviced by a NISSAN dealer because
the fuel lines are under high pressure
even when the engine is off.CAUTION
cDo not work under the hood while the
engine is hot. Turn the engine off and
wait until it cools down.
cAvoid contact with used engine oil and
coolant. Improperly disposed engine
oil, engine coolant and/or other vehicle
fluids can damage the environment. Al-
ways conform to local regulations for
disposal of vehicle fluid.
