Shift lock release
If the battery is discharged, the shift selector lever
may not be moved from the P (Park) position even
with the brake pedal depressed.
To move the shift selector lever, release the shift
lock. The shift selector lever can be moved to N
(Neutral) . However, the steering wheel will be
locked unless the ignition switch is turned to the
ON position. This allows the vehicle to be moved
if the battery is discharged.To push the shift lock release, complete the fol-
lowing procedure:
1. Turn the ignition switch to the LOCK posi-
tion and remove the key (if so equipped)
2. Apply the parking brake.
3. Remove the shift lock release cover as
shown.
4. Insert a small screwdriver in the shift lock
release slot and push down.
5. Press the shift lever button and move the
shift selector lever to the N (Neutral) position
while holding down the shift lock release.6. Turn the ignition switch to the ON position to
unlock the steering wheel. Now the vehicle
may be moved to the desired location.
If the shift selector lever cannot be moved out of
P (Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.
WARNING
If the selector lever cannot be moved from
the P (Park) position while the engine is
running and the brake pedal is depressed,
the stop lights may not work. Malfunction-
ing stop lights could cause an accident
injuring yourself and others.
Accelerator downshift

Overdrive switch (if so equipped)
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and the
shift selector lever in the D (Drive)
position, the transmission upshifts
into Overdrive as vehicle speed
increases.
Overdrive does not engage until the engine
has reached operating temperature.
OFF: For driving up and down long
slopes where engine braking is nec-
essary push the Overdrive switch
once. The O/D OFF indicator light
in the instrument panel comes on at
this time.
When cruising at a low speed or climbing a
gentle slope, you may feel uncomfortable shift
shocks as the transmission shifts into and out of
Overdrive repeatedly. In this case, depress the
Overdrive switch to turn the Overdrive off. The
O/D OFF indicator light in the instrument panel
comes on at this time.
When driving conditions change, depress the
Overdrive switch to turn the Overdrive on.
Remember not to drive at high speeds for ex-
tended periods of time with the Overdrive off.
This reduces fuel economy.
WARNING
cBe sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
cDo not release the parking brake from
outside the vehicle.
cDo not use the gear shift in place of the
parking brake. When parking, be sure
the parking brake is fully engaged.
cDo not leave children unattended in a
vehicle. They could release the parking
brake and cause an accident.

CAUTION
During the first 1,200 miles (2,000 km) ,
follow these recommendations to obtain
maximum engine performance and en-
sure the future reliability and economy of
your new vehicle. Failure to follow these
recommendations may result in short-
ened engine life and reduced engine
performance.
cAvoid driving for long periods at constant
speed, either fast or slow, and do not run the
engine over 4,000 rpm.
cDo not accelerate at full throttle in any gear.
cAvoid quick starts.
cAvoid hard braking as much as possible.
cDo not tow a trailer for the first 500 miles
(800 km) . Your engine, axle or other parts
could be damaged.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.
CAUTION
cDo not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driv-
ing on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.
If the 4WD warning light turns on when
you are driving on dry hard surface
roads:
– in the 4H position, shift the 4WD shift
switch to 2WD.
– in the 4LO position for all mode 4WD
vehicles, stop the vehicle and shift
the transmission selector to the N
position with the brake pedal de-
pressed and shift the 4WD shift
switch to 2WD.
– in the 4LO position for part time 4WD
vehicles, stop the vehicle and shift
the transmission selector to the N
position with the brake pedal de-
pressed and shift the 4WD shift
switch to 2WD.
cIf the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.cThe transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.
All mode 4WD system (if so
equipped)
The all mode 4WD system provides 4 positions
(AUTO, 2WD, 4H and 4LO) , so you can select
the desired drive mode according to the driving
conditions.

The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must depress the switch to select 4LO,
and the vehicle MUST be stationary and the
automatic transmission selector lever in
the N position when changing into or out of
4LO.
WARNING
When 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 unexpectedly move even
if the automatic transmission is in the P
position.
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
traction. Avoid raising vehicle speed ex-
cessively, as the maximum speed is ap-
proximately 31 MPH (50 km/h) .
cWhen driving straight, shift the 4WD
shift switch to the 2WD, AUTO 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, AUTO and 4H) while driving
on steep downhill grades. Use the en-
gine brake and low automatic transmis-
sion gears (D1 or D2) for engine
braking.
cDo not operate the 4WD shift switch
(between 2WD, AUTO 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 or AUTO 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 AUTO, 4H or
4LO.
cDrive carefully according to the road surface
conditions.
When the vehicle is stuck,
cPlace stones or wooden blocks under the
tires to free the vehicle.
cSet the 4WD shift switch to 4H or 4LO.

4WD shift switch operations
cShift the 4WD shift switch to either the
2WD, AUTO (Type A only) , 4H or 4LO po-
sition, depending on driving conditions.
cWith the switch set to the AUTO position
(Type A only) , distribution of torque to the
front and rear wheels changes automatically,
depending on road conditions encountered
[ratio; 0 : 100 (2WD)!50 : 50 (4WD)].
This results in improved driving stability.cIf the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the key switch is
turned off while in the AUTO (Type A
only) , 4H or 4LO, 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.
