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.

*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

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.
