M1 (First):
Use this position when climbing steep hills slowly
or driving slowly through deep snow, sand or
mud, or for maximum engine braking on steep
downhill grades.
M1 will be displayed on the position indicator on
the meter.● Remember not to drive at high speeds for
extended periods of time in lower than M4
range. This reduces fuel economy.
When shifting up:
Move the shift lever to the + (up) side. (Shifts to
higher range.)
When shifting down:
Move the shift lever to the (down) side. (Shifts
to lower range.)
● The transmission will automatically down-
shift the gears. (For example, if you select the
3rd range, the transmission will shift down
between the 3rd and 1st gears.)
● Moving the shift lever rapidly to the same
side twice will shift the ranges in succession. When canceling the manual shift mode:
Press the manual shift mode button
Ato return
the transmission to the normal driving mode.
● In the manual shift mode, the transmis-
sion may not shift to the selected gear
immediately because of vehicle speed.
The transmission will up or down shift
when vehicle speed matches the pro-
grammed transmission shift points.
This helps maintain driving perfor-
mance and reduces the chance of ve-
hicle damage or loss of control.
● In the manual shift mode, the transmis-
sion will not up shift to a higher gear
than is manually selected. When the
vehicle speed decreases, the transmis-
sion automatically shifts down and
shifts to 1st gear before the vehicle
comes to a stop.
Shift lock release
If the battery is discharged, the shift lever may not
be moved from the P (Park) position even with the
brake pedal depressed.
To move the shift lever, release the shift lock. The
shift lever can be moved to N (Neutral) . However,
for models without the NISSAN vehicle immobi-
lizer system, 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 key to the LOCK position and remove the key
2. Apply the parking brake.
3. On vehicles equipped with a column shifter, tilt the steering wheel down to the lowest
position.
4. Remove the shift lock release cover as shown. 5. Use a protective cloth on the end of a small
screwdriver before inserting it in the shift
lock release slot and pushing down.
6. Move the shift lever to the N (Neutral) posi- tion while holding down the shift lock re-
lease.
7. For models without the NISSAN vehicle im- mobilizer system, turn the key to the ON
position to unlock the steering wheel.
8. Now the vehicle may be moved to the de- sired location.
If the shift lever cannot be moved out of P (Park) ,
have a NISSAN dealer check the automatic
transmission system as soon as possible.
WARNING
If the shift lever cannot be moved from the
P (Park) position while the engine is run-
ning and the brake pedal is depressed, the
stop lights may not work. Malfunctioning
stop lights could cause an accident injur-
ing yourself and others.
Accelerator downshift
— in D (Drive) 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.
Fail-safe
When the fail-safe operation occurs, please note
that the transmission will be locked in any of the
forward gears according to the condition.
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
switch OFF and wait for 3 seconds. Then
turn the ignition switch back to the ON
position. The vehicle should return to its
normal operating condition. If it does not
return to its normal operating condition,
have a NISSAN dealer check the transmis-
sion and repair it if necessary.

The cruise control is automatically canceled and
the SET light in the vehicle information display
goes out if:● You depress the brake pedal while pushing
the ACCEL/RES or SET/COAST switch.
The preset speed is deleted from memory.
● The vehicle slows down more than 8 MPH
(13 km/h) below the set speed.
● You move the shift lever to N (Neutral) .
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 ensure
the future reliability and economy of your
new vehicle. Failure to follow these rec-
ommendations may result in shortened
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 mi
(805 km) . Your engine, axle or other parts
could be damaged.
BREAK-IN SCHEDULE
5-22Starting and driving

Follow these easy-to-use Fuel Efficient Driving
Tips to help you achieve the most fuel economy
from your vehicle.1. Use Smooth Accelerator and Brake
Pedal Application
● Avoid rapid starts and stops.
● Use smooth, gentle accelerator and
brake application whenever possible.
● Maintain constant speed while commut-
ing and coast whenever possible.
2. Maintain Constant Speed
● Look ahead to try and anticipate and mini-
mize stops.
● Synchronizing your speed with traffic
lights allows you to reduce your number
of stops.
● Maintaining a steady speed can minimize
red light stops and improve fuel effi-
ciency.
3. Use Air Conditioning (A/C) at Higher
Vehicle Speeds
● Below 40 MPH (64 km/h), it is more
efficient to open windows to cool the
vehicle due to reduced engine load. ●
Above 40 MPH (64 km/h), it is more
efficient to use A/C to cool the vehicle
due to increased aerodynamic drag.
● Recirculating the cool air in the cabin
when the A/C is on reduces cooling load.
4. Drive at Economical Speeds and Dis-
tances
● Observing the speed limit and not ex-
ceeding 60 MPH (97 km/h) (where le-
gally allowed) can improve fuel efficiency
due to reduced aerodynamic drag.
● Maintaining a safe following distance be-
hind other vehicles reduces unnecessary
braking.
● Safely monitoring traffic to anticipate
changes in speed permits reduced brak-
ing and smooth acceleration changes.
● Select a gear range suitable to road con-
ditions.
5. Use Cruise Control
● Using cruise control during highway driv-
ing helps maintain a steady speed.
● Cruise control is particularly effective in
providing fuel savings when driving on flat
terrains. 6.
Plan for the Shortest Route
● Utilize a map or navigation system to de-
termine the best route to save time.
7. Avoid Idling
● Shutting off your engine when safe for
stops exceeding 30–60 seconds saves
fuel and reduces emissions.
8. Buy an Automated Pass for Toll Roads
● Automated passes permit drivers to use
special lanes to maintain cruising speed
through the toll and avoid stopping and
starting.
9. Winter Warm Up
● Limit idling time to minimize impact to fuel
economy.
● Vehicles typically need no more than
30 seconds of idling at start-up to effec-
tively circulate the engine oil before driv-
ing.
● Your vehicle will reach its ideal operating
temperature more quickly while driving
versus idling.
FUEL EFFICIENT DRIVING TIPS
Starting and driving5-23

10.Keeping your Vehicle Cool
● Park your vehicle in a covered parking
area or in the shade whenever possible.
● When entering a hot vehicle, opening the
windows will help to reduce the inside
temperature faster, resulting in reduced
demand on your A/C system. ●
Keep your engine tuned up.
● Follow the recommended scheduled main-
tenance.
● Keep the tires inflated to the correct pres-
sure. Low tire pressure increases tire wear
and lowers fuel economy.
● Keep the wheels in correct alignment. Im-
proper alignment increases tire wear and
lowers fuel economy.
● For vehicles equipped with
, use 4H
or 4L position only when necessary. Four-
wheel drive operation lowers fuel economy.
● Use the recommended viscosity engine oil.
For additional information, refer to “Engine
oil and oil filter recommendations” in the
“Technical and consumer information” sec-
tion of this manual.
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
(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.

5-24Starting and driving

*1: Before moving the shift lever from (N) Neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedure is completedand 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 light illuminates, have the system checked by a NISSAN dealer.
3. Apply the parking brake, depress the brake pedal and move the shift lever to (N) Neutral position.
4. With the brake pedal depressed, move the 4WD shift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the shift lever 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. For additional information, refer to “Vehicle Dynamic Control (VDC) system” in this section.
Starting and driving5-27

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 lever to
(N) Neutral, and depress the brake pedal.
The switch must be pushed and turned to
select 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 lever is shifted from the
“N” position to any other gear when the
4LO indicator light is blinking, the ve-
hicle 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) 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.
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.
