cAccelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
cDrive at moderate speeds on the highway.
Driving at high speed lowers fuel economy.
cAvoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
cUse a proper gear range which suits road
conditions. On level roads, shift into high
gear as soon as possible.
cAvoid unnecessary engine idling.
cKeep your engine tuned up.
cFollow the recommended periodic mainte-
nance schedule.
cKeep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
cKeep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
cAir conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.cWhen cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
c
Use 4H or 4L position only when
necessary. Four-wheel drive operation low-
ers fuel economy.
WARNING
cFor 4WD equipped vehicles, do not at-
tempt to raise two wheels off the
ground and shift the transmission to
any drive or reverse position with the
engine running. Doing so may result in
drivetrain damage or unexpected ve-
hicle movement which could result in
serious vehicle damage or personal
injury.
cDo not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer
(such as the dynamometers used by
some states for emissions testing) , or
similar equipment even if the other two
wheels are raised off the ground. Make
sure you inform test facility personnel
that your vehicle is equipped with 4WD
before it is placed on a dynamometer.
Using the wrong test equipment may
result in drivetrain damage or unex-
pected vehicle movement which could
result in serious vehicle damage or per-
sonal injury.

The transfer case 4WD shift 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 shift 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, shift the transmission
selector or transmission shift lever to Neu-
tral (N) , and for automatic transmission
vehicles depress the brake pedal or for
manual transmission vehicles depress the
clutch pedal. The switch must be de-
pressed and turned when changing into or
out of 4LO.
WARNING
cWhen 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 unexpect-
edly move even if the automatic trans-
mission is in the P position.cThe 4LO indicator light must stop blink-
ing and remain illuminated or turn off
before shifting the transmission into
gear. If the transmission selector or
transmission shift lever is shifted from
the (N) position to any other gear when
the 4LO indicator light is blinking, the
vehicle may move unexpectedly.
CAUTION
cNever shift the 4WD shift switch be-
tween 4LO and 4H while driving.
cThe 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 62.5 MPH (100 km/h) in 4H
is not recommended.
cThe 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) .
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 (be-
tween 2WD and 4H) while driving on
steep downhill grades. Use the engine
brake and low automatic transmission
gears (D1 or D2) or manual transmis-
sion (1st gear or 2nd gear) for engine
braking.
cDo not operate the 4WD shift switch
(between 2WD and 4H) with the rear
wheels spinning.
cDo 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 position under these conditions.
cThe 4WD transfer case may not be
shifted between 4H and 4LO at low am-
bient temperatures 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,
cSet the 4WD shift switch to 4H or 4LO.
cDrive carefully according to the road surface
conditions.

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.
c
If the 4WD shift switch is operated while
making a turn, accelerating or deceler-
ating or if the key switch is turned off
while in the 4H or 4LO position, 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) or
manual transmission (1st gear or 2nd
gear) for engine 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
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.

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
light turns 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) 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.
