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.

5-20Starting and driving

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 (if so
equipped) 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 lever to N (Neu-
tral) (automatic transmission) . 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).
5-22Starting and driving

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. 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 effi-
cient to open windows to cool the vehicle
due to reduced engine load. ●
Above 40 mph (64 km/h), it is more effi-
cient 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 legally
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.
BREAK-IN SCHEDULE FUEL EFFICIENT DRIVING TIPS
Starting and driving5-23

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. 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.
INCREASING FUEL ECONOMY
5-24Starting and driving

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.
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 lever to the N
position with the brake pedal de-
pressed and shift the 4WD shift
switch to 2WD.
– in the 4LO position for manual trans- mission vehicles, stop the vehicle
and shift the shift lever to the N po-
sition with the clutch pedal de-
pressed and shift the 4WD shift
switch to 2WD. ●
If the warning light is still on after the
above operation, have your vehicle
checked as soon as possible. It is rec-
ommended you visit a NISSAN dealer
for this service.
TRANSFER CASE SHIFTING
PROCEDURES
The part time 4WD system provides 3 positions
(2WD, 4H and 4LO) , so you can select the
desired drive mode according to the driving con-
ditions.
USING FOUR WHEEL DRIVE
(4WD) (if so equipped)
Starting and driving5-25

*1: Before moving the shift lever from neutral, wait until the 4LO indicator light stays on steady. This indicates that the 4WD shift procedure is completed andthe 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 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 lever to Neutral position. For manual transmission vehicles, move the 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 4WD shift switch to desired mode.
- Be sure to wait until the transfer gear change completes before shifting the 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 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
Neutral (N) , 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 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) 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.
5-28Starting 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 lever is shifted to N or P.
This occurs because the transfer clutch
is released and not because of a mal-
function.
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.
