AUTOMATIC TRANSMISSIONThe automatic transmission in your vehicle is
electronically controlled by a transmission con-
trol module to produce maximum power and
smooth operation.
Shown on the following pages are the recom-
mended operating procedures for this transmis-
sion. Follow these procedures for maximum ve-
hicle performance and driving enjoyment. If your
vehicle is equipped with four wheel drive, see
“Using four wheel drive” later in this section.
After starting the engine, fully depress the
foot brake pedal and push the selector lever
button before shifting the selector lever to the
R, N, D, 2 or 1 position. Be sure the vehicle is
fully stopped before attempting to shift the
selector lever.
This automatic transmission is designed
so that the foot brake pedal MUST be
depressed before shifting from P to any
drive position while the ignition switch is
ON.
The selector lever cannot be moved out of
P and into any of the other gear positions if
the ignition key is turned to LOCK or if the
key is removed from the switch.
1. Keep the foot brake pedal depressed andpush the selector lever button to shift into a
driving gear.
2. Release the parking brake and foot brake,
then gradually start the vehicle in motion.
WARNING
Do not depress the accelerator pedal
while shifting from P or Nto R, D, 2 or
1. Always depress the brake pedal
until shifting is completed. Failure to
do so could cause you to lose control
and have an accident.
Cold engine idle speed is high, so use
caution when shifting into a forward
or reverse gear before the engine has
warmed up.
Never shift to P or R while the vehicle
is moving forward. Never shift to P or
D while vehicle is moving rearward.
These could cause an accident.
On slippery roads, do not downshift.
This may cause a loss of control.
CAUTION
When stopping the vehicle on an uphill
grade, do not hold the vehicle by de-
pressing the accelerator pedal. The foot
brake should be used for this purpose.

your NISSAN dealer check the automatic trans-
mission system as soon as possible.
WARNING
If the selector lever cannot be moved
from the P position while the engine is
running and the brake pedal is de-
pressed, the stop lights may not work.
Malfunctioning stop lights could cause
an accident injuring yourself and others.
Accelerator downshift
— In D position —For rapid passing or hill climbing, fully depress
the accelerator pedal to the floor. This shifts the
transmission down into second gear or first gear,
depending on the vehicle speed.
Overdrive switchEach time your vehicle is started, the transmis-
sion is automatically reset to overdrive on.
ON: For normal driving the overdrive switch
is engaged. The transmission is up-
shifted into overdrive as the vehicle
speed increases.
The overdrive does not engage until the
engine has warmed up.
OFF: For driving up and down long slopes
where engine braking would be advan-
tageous, push the overdrive switch. The
O/D OFF light illuminates. When cruis-

ing at a low speed or climbing a gentle
slope, you may feel uncomfortable shift
shocks as the transmission shifts be-
tween 3rd and overdrive repeatedly. In
this case, press the overdrive switch.
The O/D OFF indicator light comes on
at this time.
When driving conditions change, press the over-
drive switch again. The O/D OFF indicator light
goes out.
Remember not to drive at high speeds for ex-
tended periods of time with the O/D OFF light
illuminated. This reduces the fuel economy.
Fail-safeWhen the Fail-safe operation occurs, the next
time the key is turned to the ON position, the
O/D OFF light will blink for approximately 8
seconds after coming on for 2 seconds. While
the vehicle can be driven under these circum-
stances please note that the gears in the auto-
matic transmission may be locked in third gear.
If the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the Fail-safe
system may be activated. This will occur
even if all electrical circuits are functioning
properly. In this case, turn the ignition key
OFF and wait for 3 seconds. Then turn thekey back to the ONposition. The vehicle
should return to its normal operating con-
dition. If it does not return to its normal
operating condition have your NISSAN
dealer check the transmission and repair if
necessary.

WARNING
Do not use the cruise control when driv-
ing under the following conditions:
when it is not possible to keep the
vehicle at a set speed.
in heavy traffic or in traffic that varies
in speed.
on winding or hilly roads.
on slippery roads (rain, snow, ice,
etc.)
in very windy areas.
Doing so could cause a loss of vehicle
control and result in an accident.
CAUTION
On manual transmission models, do not
shift into N(Neutral) without depressing
the clutch pedal when the cruise control
is set. Should this occur, depress the
clutch pedal and turn the main switchoff immediately. Failure to do so may
cause engine damage.
PRECAUTIONS ON CRUISE
CONTROLIf the engine coolant temperature becomes
excessively high, the cruise control system
will automatically be canceled.
If the cruise control system malfunctions, it
cancels automatically. The SET indicator light
in the instrument panel then blinks to warn
the driver.
If the SET indicator light blinks, turn the
cruise control main switch off and have the
system checked by your NISSAN dealer.
The SET indicator light may blink when the
cruise control main switch is turned on while
pushing the RES/ACCEL, COAST/
SET, or CANCEL switch (located on the
steering wheel). To properly set the cruise
control system, perform the preceding steps
in the order indicated.
CRUISE CONTROL OPERATIONSThe cruise control allows driving at a fixed speed
between 25 to 89 MPH (40 to 144 km/h)
without keeping your foot on the accelerator
pedal.
To turn on the cruise control,push the main
switch on. The CRUISE indicator light on the
meter panel will come on.

If the cruise control system malfunctions, it
will cancel automatically. The SET indicator in
the meter assembly will then blink to warn the
driver.
When the SET indicator blinks, turn the
cruise control switch (Main switch) OFF and
have the system checked by your NISSAN
dealer.During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum en-
gine performance and ensure the future reliability
and economy of your new vehicle. Failure to
follow these recommendations may result in
shortened engine life and reduced engine per-
formance.
Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
Do not accelerate at full throttle in any gear.
Avoid quick starts.
Avoid hard braking as much as possible.
Do not tow a trailer for the first 500 miles
(800 km).Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
Drive at moderate speeds on the highway.
Driving at high speed will lower fuel economy.
Avoid unnecessary stopping and braking.
Maintain a safe distance behind other ve-
hicles.
Use a proper gear range which suits road
conditions. On level roads, shift into high gear
as soon as possible.
Avoid unnecessary engine idling.
Keep your engine tuned up.

TRANSFER CASE:AUTOMATIC TRANSMISSION MODELS SHIFT PROCEDURE
From 2H to 4HMove the transfer lever to 4H. This can be done at any speed up to 50 MPH (80 km/h), and it is not necessary to move the selector lever
to the N position. Perform this operation when driving straight.
From 4H to 2HMove the transfer lever to 2H. This can be done at any speed up to 50 MPH (80 km/h), and it is not necessary to move the selector lever
to the N position. Perform this operation when driving straight.
From 4H or 4L to 4L or
4H1. Stop the vehicle.
Keep the engine running.
2. Move the selector lever to the N position.
3. Depress the transfer lever and move it to the desired 4L or 4H position.
From 2H to 4L1. Stop the vehicle.
Keep the engine running.
2. Move the selector lever to the N position.
3. Depress the transfer lever and move it to 4L. Change gears quickly and smoothly.
From 4L to 2H1. Stop the vehicle.
Keep the engine running.
2. Move the selector lever to the N position.
3. Depress the transfer lever and move it to 2H.
When moving the transfer lever from 4H or 4L to 4L or 4H, you must always move it quickly through the N position. If you are slow to shift, the engine idle speed
will allow the transfer gears to speed up and gear clashing will occur.
Do not move the transfer lever from 4H or 4L to 4L or 4H, from 2H to 4L and from 4L to 2H with the engine turned off. Otherwise, you will have difficulty moving
the transfer lever to the desired position.
Do not leave the transfer lever in the N position with the engine running. Stopping in the N position of the transfer case may cause gear grinding when selecting
another gear. Changing the transfer case gear quickly and smoothly will eliminate this.5-24

*1:The transfer 4LO position indicator light
may blink. Stop the vehicle. Be sure to
shift the 4WD shift switch after the auto-
matic transmission lever has been shifted
to the N position. If the indicator light
keeps blinking after the 4WD shift proce-
dure in the previous page, drive slowly
without abrupt maneuvers for a while.
Then the light will turn on or off.
Avoid making a turn or abrupt starts while
shifting to 4LO. Otherwise gears may
grind, damaging the drive system.
*2: Make sure the transfer 4LO position indicator
light turns on when you shift the 4WD shift
switch to 4LO.
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 push the switch in to select 4LO,
and the vehicle MUST be stationary and
the automatic transmission selector lever
is in the Nposition 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 unexpect-
edly move even if the automatic trans-
mission is in the P position.
CAUTION
Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
The 4H position provides greater
power and traction. Avoid excessive
speed, as it will cause increased fuel
consumption and higher oil tempera-
ture, and could damage drivetrain
components. Speeds over 50 MPH
(80 km/h) in 4H are not recom-
mended.
The 4LO position provides maximum
power and traction. Avoid raising ve-hicle speed excessively, as the maxi-
mum speed is approximately 30 MPH
(50 km/h).
When 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 revers-
ing.
Do not shift the 4WD shift switch
(between 2WD, AUTO and 4H) while
driving on steep downhill grades. Use
the engine brake.
Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with
the rear wheels spinning.
Do not drive on dry hard surface
roads in the 4H or 4LO position. Driv-
ing on dry hard surfaces in 4H or 4LO
may cause unnecessary noise and
tire wear. We recommend driving in
the 2WD or AUTO position under
these conditions.
