1 (Low gear):
Use this position when climbing steep hills slowly
or slow driving through deep snow, sand or mud,
or for maximum engine braking on steep downhill
grades.
Do not downshift into the 1 position at speeds
over the following and do not exceed the follow-
ing speeds in the 1 position.2WD:37 MPH (60 km/h)
4H: 37 MPH (60 km/h)
4LO: 12 MPH (20 km/h)
Shift lock release
If the battery is discharged, the shift selector may
not be moved from the P (Park) position even with
the brake pedal depressed.
To move the shift selector, release the shift lock.
The shift selector can be moved to N (Neutral) .
However, the steering wheel will be locked un-
less the ignition switch is placed in the ON posi-
tion (for models with a steering lock mechanism) .
This allows the vehicle to be moved if the battery
is discharged. To push the shift lock release, complete the fol-
lowing procedure:
1. Place the ignition switch in the LOCK posi- tion and remove the key.
2. Apply the parking brake.
3. Remove the shift lock release cover as shown.
4. Use a protective cloth on the tip of a small screwdriver before inserting it in the shift
lock release slot and pushing down.
5. Move the shift selector to the N (Neutral) position while holding down the shift lock
release.
6. Place the ignition switch in the ON position to unlock the steering wheel (for models with
a steering lock mechanism) .
7. Now the vehicle may be moved to the de- sired location.
If the shift selector cannot be moved out of P
(Park) , have a NISSAN dealer check the auto-
matic transmission system as soon as possible.

WARNING
If the shift selector 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
— in D position —
For passing or hill climbing, depress the accel-
erator pedal to the floor. This shifts the transmis-
sion down into a lower gear, depending on the
vehicle speed.
Overdrive switch
Each time your vehicle is started, the transmis-
sion is automatically “reset” to overdrive ON.
ON: With the engine running and theshift selector 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 longslopes 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.

MANUAL TRANSMISSION (if so
equipped)
WARNING
●Do not downshift abruptly on slippery
roads. This may cause a loss of control.
● Do not over-rev the engine when shift-
ing to a lower gear. This may cause a
loss of control or engine damage.
CAUTION
● Do not rest your foot on the clutch pedal
while driving. This may cause clutch
damage.
● Fully depress the clutch pedal before
shifting to help prevent transmission
damage.
● Stop your vehicle completely before
shifting into R (Reverse) .
● When the vehicle is stopped with the
engine running (for example, at a stop
light) , shift to N (Neutral) and release
the clutch pedal with the foot brake
applied.
Shifting
To change gears, or when upshifting or down-
shifting, depress the clutch pedal fully, shift into
the appropriate gear, then release the clutch
slowly and smoothly.
To ensure smooth gear changes, fully depress
the clutch pedal before operating the shift selec-
tor. If the clutch pedal is not fully depressed
before the transmission is shifted, a gear noise
may be heard. Transmission damage could oc-
cur.
Start the vehicle in 1st gear and shift to 2nd, 3rd,
4th, 5th and 6th gear in sequence according to
vehicle speed. To back up depress the shift selector and then
move it to the R (Reverse) position after stopping
the vehicle completely.
If it is difficult to move the shift selector into R
(Reverse) or 1 (First) , shift into N (Neutral) , then
release the clutch pedal. Fully depress the clutch
pedal again and shift into R (Reverse) or 1 (First) .
If your vehicle is equipped with 4-wheel drive, see
“Transfer case shifting procedures” later in this
section.

●Be sure the parking brake is fully re-
leased before driving. Failure to do so
can cause brake failure and lead to an
accident.
● Do not release the parking brake from
outside the vehicle.
● Do not use the shift selector in place of
the parking brake. When parking, be
sure the parking brake is fully engaged.
● Do not leave children unattended in a
vehicle. They could release the parking
brake and cause an accident.
PARKING BRAKE
Starting and driving5-19

●The SET indicator light may blink when the
cruise control main switch is turned ON
while pushing the ACCEL/RES,
COAST/SET, or CANCEL switch (located
on the steering wheel) . To properly set the
cruise control system, use the following pro-
cedures.
WARNING
Do not use the cruise control when driving
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 switch off imme-
diately. Failure to do so may cause engine
damage.
CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed be-
tween 25 - 89 MPH (40 - 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control, push the main
switch. The CRUISE indicator light in the instru-
ment panel comes on.
To set cruising speed, accelerate the vehicle to
the desired speed, push the COAST/SET switch
and release it. The SET indicator light in the
instrument panel comes on. Take your foot off the
accelerator pedal. Your vehicle maintains the set
speed.
● To pass another vehicle, depress the ac-
celerator pedal. When you release the
pedal, the vehicle returns to the previously
set speed. ●
The vehicle may not maintain the set speed
when going up or down steep hills. If this
happens, drive without the cruise control.
To cancel the preset speed, use one of the
following three methods.
● Push the CANCEL button; the SET indicator
light in the instrument panel goes out.
● Tap the brake pedal; the SET indicator light
goes out.
● Turn the main switch off. Both the CRUISE
indicator light and SET indicator light in the
instrument panel go out.
The cruise control is automatically canceled and
the SET light in the instrument panel goes out if: ● you depress the brake or clutch pedal while
pushing the ACCEL/RES or COAST/SET
switch. The preset speed is deleted from
memory.
● the vehicle slows down more than 8 MPH
(13 km/h) below the set speed.
● you depress the clutch pedal (manual trans-
mission) , or move the shift selector to N
(Neutral) (automatic transmission) .
Starting and driving5-21

To reset at a faster cruising speed,use one
of the following three methods.
● Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
● Push and hold the ACCEL/RES switch.
When the vehicle attains the speed you de-
sire, release the switch.
● Push and release the ACCEL/RES switch.
Each time you do this, the set speed in-
creases by about 1 MPH (1.6 km/h) .
To reset at a slower cruising speed, use one
of the following three methods.
● Lightly tap the brake pedal. When the ve-
hicle attains the desired speed, push the
COAST/SET switch and release it.
● Push and hold the COAST/SET switch. Re-
lease the switch when the vehicle slows to
the desired speed.
● Push and release the COAST/SET switch.
Each time you do this, the set speed de-
creases by about 1 MPH (1.6 km/h) .
To resume the preset speed, push and re-
lease the ACCEL/RES switch. The vehicle re-
turns to the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h) .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.
● Avoid driving for long periods at constant
speed, either fast or slow, and 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) . Your engine, axle or other parts
could be damaged. ●
Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
Driving at high speed lowers 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.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the front wheels in correct alignment.
Improper alignment increases tire wear and
lowers fuel economy.
● Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.
BREAK-IN SCHEDULE INCREASING FUEL ECONOMY
5-22Starting and driving

●When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
WARNING
● For 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.
● Do not attempt to test a 4WD equipped
vehicle on a 2-wheel dynamometer, 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
● Do 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 automatic transmission vehicles, stop the ve-
hicle and shift the shift selector to
the N (Neutral) position with the
brake pedal depressed and shift the
4WD shift switch to 2WD.
– in the 4LO position for manual trans- mission vehicles, stop the vehicle
and shift the shift selector to the N
(Neutral) position with the clutch
pedal depressed and shift the 4WD
shift switch to 2WD.
● If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.
USING FOUR WHEEL DRIVE
(4WD) (if so equipped)
Starting and driving5-23

*1: Before moving the shift selector from N (Neutral) position, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedureis 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 N (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 switch OFF.
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 shift selector to N (Neutral) position. For manual transmission vehicles, move the shift selector to N (Neutral) position.
4. With the brake pedal depressed on automatic transmission vehicles or with the clutch pedal depressed on manual transmission vehicles, move the 4WD shift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the shift selector from N (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 will also turn on when
4LO is selected. See “Vehicle Dynamic Control (VDC) system” later in this section.
Starting and driving5-25

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 shift selector
to N (Neutral) position, and for automatic
transmission vehicles depress the brake
pedal or for manual transmission vehicles
depress the clutch pedal. The switch must
be depressed and turned 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. ●
The 4LO indicator light must stop blink-
ing and remain illuminated or turn off
before shifting the transmission into
gear. If the shift selector is shifted from
the (N) position to any other gear when
the 4LO indicator light is blinking, the
vehicle may move unexpectedly.
CAUTION
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
● The 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 MPH (100 km/h) in 4H is
not recommended
● The 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) .
● When 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. ●
Do 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.
● Do not operate the 4WD shift switch
(between 2WD and 4H) with the rear
wheels spinning.
● Do 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.
● The 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, ● Set the 4WD shift switch to 4H or 4LO.
● Drive carefully according to the road surface
conditions.
5-26Starting and driving

When the vehicle is stuck,● Set the 4WD shift switch to 4H or 4LO.
● Use 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.
● If it is difficult to free the vehicle, rock the
vehicle back and forth between reverse and
drive gears.
● If 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
● Do not spin the tires excessively. Tires
will sink deep into the mud, making it
difficult to free the vehicle.
● Avoid shifting gears with the engine
running at high speeds as this may
cause malfunction.
4WD shift switch operations
● Shift the 4WD shift switch to either the
2WD, 4H or 4LO position, depending on
driving conditions.
● If the 4WD shift switch is operated
while making a turn, accelerating or
decelerating or if the key switch is
turned off while in the 4H or 4LO posi-
tion, you may feel a jolt. This is not
abnormal. ●
When the vehicle is stopped after mak-
ing a turn, you may feel a slight jolt
after the shift selector is shifted to N or
P. This occurs because the transfer
clutch is released and not because of a
malfunction.
CAUTION
● When 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.
● Do 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.
● Do not operate the 4WD shift switch
with the rear wheels spinning.
● Before placing the 4WD shift switch in
the 4H position from 2WD, ensure the
vehicle speed is less than 62 MPH (100
km/h) . Failure to do so can damage the
4WD system.
● Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
