backward.

Many hills are too steep for any ve-
hicle. If you drive up them, you may
stall. If you drive down them, you may
not be able to control your speed. If
you drive across them, you may roll
over.

Do not shift selector lever while driv-
ing on downhill grades as this could
cause loss of control of the vehicle.

Be sure to use the engine brake. The
foot brake performance may be re-
duced, resulting in a possible acci-
dent.

Stay alert when driving to the top of a
hill. At the top there could be a drop-
off or other hazard that could cause
an accident.

If your engine stalls or you cannot
make it to the top of a steep hill,
never attempt to turn around. Your
vehicle could tip or roll over. Always
back straight down in R (Reverse)
range. Never back down in N (Neu-tral), using only the brake, as this
could cause loss of control.

Heavy braking going down a hill
could cause your brakes to overheat
and fade, resulting in loss of control
and an accident. Apply brakes lightly
and use a low range to control your
speed.

Unsecured cargo can be thrown
around when driving over rough ter-
rain. Properly secure all cargo so it
will not be thrown forward and cause
injury to you or your passengers.

To avoid raising the center of gravity
excessively, do not exceed the rated
capacity of the roof rack (if so
equipped) and evenly distribute the
load. Secure heavy loads in the cargo
area as far forward and as low as
possible. Do not equip the vehicle
with tires larger than specified in this
manual. This could cause your ve-
hicle to roll over.

Do not grip the inside or spokes ofthe steering wheel when driving off-
road. The steering wheel could move
suddenly and injure your hands. In-
stead drive with your fingers and
thumbs on the outside of the rim.

Before operating the vehicle, ensure
that the driver and all passengers
have their seat belts fastened.

Always drive with the floor mats in
place as the floor may become hot.

Lower your speed when encountering
strong crosswinds. With a higher
center of gravity, your NISSAN is
more affected by strong side winds.
Slower speeds ensure better vehicle
control.

Do not drive beyond the performance
of the tires, even with AWD engaged.
Accelerating quickly, sharp steering
maneuvers or sudden braking may
cause loss of control.

If at all possible, avoid sharp turning
maneuvers, particularly at high

speeds. Your NISSAN all wheel drive
vehicle has a higher center of gravity
than a two wheel drive vehicle. The
vehicle is not designed for cornering
at the same speeds as conventional
two wheel drive vehicles. Failure to
operate this vehicle correctly could
result in loss of control and/or a roll
over accident.

Always use tires of the same type,
size, brand, construction (bias, bias-
belted or radial), and tread pattern on
all four wheels. Install tire chains on
the front wheels when driving on slip-
pery roads and drive carefully.

Be sure to check the brakes immedi-
ately after driving in mud or water.
See “Brake system” later in this sec-
tion for wet brakes.

Avoid parking your vehicle on steep
hills. If you get out of the vehicle and
it rolls forward, backward or side-
ways, you could be injured.

Whenever you drive off-road throughsand, mud or water as deep as the
wheel hub, more frequent mainte-
nance may be required. See “Peri-
odic maintenance” in the “Service
and Maintenance Guide”.

Do not drive continuously on sandy
or muddy roads with the front wheels
spinning. The AWD warning light
blinks and the driving mode changes
to 2WD. This could reduce traction
force remarkably. Be especially care-
ful when towing a trailer. (AWD mod-
els)

Do not use 2-wheel chassis dyna-
mometers or 2-wheel free rollers.
(AWD models)

Never operate the accelerator pedal
with the front wheels raised and the
rear wheels on the ground while jack-
ing up or with the front wheels on the
roller and the rear wheels on the
ground. Otherwise, the vehicle could
jump. (AWD models)

When a wheel is suspended due torunning off the road, do not idle the
wheel excessively. (AWD models)

When the vehicle is on a free roller or
the front or rear wheels are jacked
up, do not start the engine. (AWD
models)

On CVT (Continuously Variable Transmission)
models, the ignition lock is designed so that the
key cannot be turned to LOCK and removed
until the selector lever is moved to the P (Park)
position.
When removing the key from the ignition, make
sure the selector lever is in the P (Park) position.
If the selector lever is not returned to P (Park)
position, the key cannot be moved toward
LOCK.
When the key cannot be turned toward the
LOCK position, proceed as follows to remove
the key:1. Move the selector lever into the P (Park)
position.
2. Turn the ignition key slightly in the ON direc-
tion.
3. Turn the key toward the LOCK position.
4. Remove the key.
If the key is removed from the ignition switch, the
selector lever cannot be moved from P (Park)
position.The selector lever can be moved if
the ignition switch is in the ONposition
and the foot brake pedal is depressed.
There is an OFF position in between LOCK and
ACC, although it does not show on the lock
cylinder. When the ignition is in OFF the steering
wheel is not locked.
In order for the steering wheel to be locked, it
must be turned about 1/6 of a turn clockwise
from the straight up position.
To lock the steering wheel, turn the key to
the LOCK position. Remove the key. To
unlock the steering wheel, insert the key
and turn it gently while rotating the steer-
ing wheel slightly right and left.
WARNING
Never remove or turn the key to the
LOCK position while driving. The steer-
ing wheel will lock. This may cause the
driver to lose control of the vehicle and
could result in serious vehicle damage
and/or personal injury.KEY POSITIONSThe switch includes an anti-theft steering lock
device.
LOCK (Normal parking position) (0)
The ignition key can only be removed when the
switch is in this position.

SYSTEMThe Nissan Vehicle Immobilizer System will not
allow the engine to start without the use of the
registered Nissan Vehicle Immobilizer System
key.
If the engine fails to start using the registered
Nissan Vehicle Immobilizer System key, it may be
due to interference caused by another Nissan
Vehicle Immobilizer System key, an automated
toll road device or automated payment device on
the key ring. Restart the engine using the follow-
ing procedures:
1. Leave the ignition switch in the ON position
for approximately 5 seconds.
2. Turn the ignition switch to the OFF or LOCK
position and wait approximately 10 seconds.
3. Repeat step 1 and 2 again.
4. Restart the engine while holding the device
(which may have caused the interference)
separate from the registered Nissan VehicleImmobilizer System key.
If this procedure allows the engine to start,
NISSAN recommends placing the registered
Nissan Vehicle Immobilizer System key on a
separate key ring to avoid interference from
other devices.
Make sure the area around the vehicle is
clear.

Maintenance items should be checked peri-
odically, for example, each time you check
engine oil.

Check that all windows and lights are clean.

Visually inspect tires for their appearance and
condition. Also, check tires for proper infla-
tion.

Lock all doors.

Position seat and adjust head restraints.

Adjust inside and outside mirrors.

Adjust the pedal position.

Fasten seat belts and ask all passengers to
do likewise.

Check the operation of warning lights when
key is turned to the ON (3) position.

cold weather.
CVT (Continuously Variable
Transmission)
Gate type shiftThe CVT in your vehicle is electronically con-
trolled by a transmission control module to pro-
duce 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.Starting the vehicleAfter starting the engine, fully depress the foot
brake pedal before shifting the selector lever to
the R (Reverse), N (Neutral), D (Drive), S (Sec-
ond) or L (Low) position. Be sure the vehicle is
fully stopped before attempting to shift the se-
lector lever.
This CVT model is designed so that the
foot brake pedal must be depressed be-
fore shifting from P (Park) to any drive
position while the ignition switch is ON.
The selector lever cannot be moved out of
P (Park) position and into any of the other
shift range if the ignition key is turned to
the LOCK, OFF or ACC position or if the
key is removed from the switch.

Shift lock releaseIf the battery charge is low or discharged, the
selector lever may not be moved from the P
(Park) position even with the brake pedal de-
pressed.
To move the selector lever, depress the brake
pedal, remove the cover using a suitable tool and
push the shift lock release button. The selector
lever can be moved to N (Neutral). This allows
the vehicle to be moved if the battery is dis-
charged.
If the selector lever cannot be moved out of P
(Park), have your NISSAN dealer check the CVTsystem as soon as possible.
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 lower range, depending
on the vehicle speed.High fluid temperature protection
modeThis transmission has a high fluid temperature
protection mode. If the fluid temperature be-
comes too high (for example, when climbing
steep grades in high temperature with heavy
loads, such as when towing a trailer), engine
power and, under some conditions, vehicle
speed will be decreased automatically to reduce
the chance of transmission damage. Vehicle
speed can be controlled with the accelerator
pedal, but the vehicle may not accelerate above
approximately 40 to 50 MPH (65 to 80 km/h).Fail-safeIf the vehicle is driven under extreme con-
ditions, such as excessive wheel spinning
and subsequent hard braking, the fail-safe
system may be activated. The MIL may
come on to indicate the fail-safe mode is
activated, see “Malfunction indicator lamp(MIL)” in the “2. Instrument and controls”
section. 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 the key back to the
ONposition. The vehicle should return to
its normal operating condition. If it does
not return to its normal operating condi-
tion, have your NISSAN dealer check the
transmission and repair if necessary.
WARNING
When the high fluid temperature protec-
tion mode or fail-safe operation occurs,
vehicle speed may be gradually re-
duced. On highways, the reduced speed
may be lower than other traffic which
could increase the chance of a collision.
Be especially careful when driving. If
necessary, pull to the side of the road at
a safe place and allow the transmission
to return to normal operation, or have it
repaired if necessary.

Move the selector lever to N (Neutral) posi-
tion. The SET indicator light will go out.
To reset at a faster cruising speed,use one
of the following three methods:
a) Depress the accelerator pedal. When the
vehicle attains the desired speed, push and
release the COAST/SET switch.
b) Push and hold the ACCEL/RES set switch.
When the vehicle attains the speed you
desire, release the switch.
c) Push, then quickly release the ACCEL/RES
set switch. Each time you do this, the set
speed will increase by about 1 MPH (1.6
km/h).
To reset at a slower cruising speed,use one
of the following three methods:
a) Lightly tap the brake pedal. When the vehicle
attains the desired speed, push the
COAST/SET switch and release it.
b) Push and hold the COAST/SET switch. Re-
lease the switch when the vehicle slows
down to the desired speed.
c) Push, then quickly release the COAST/
SET switch. Each time you do this, the setspeed will decrease by about 1 MPH (1.6
km/h).
To resume the preset speed,push and re-
lease the RES/ACCEL set switch. The vehicle
will resume the last set cruising speed when the
vehicle speed is over 25 MPH (40 km/h).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).
BREAK-INSCHEDULE
5-16
Starting and driving


03.1.28/Z50-D/V5.0


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.

Follow the recommended periodic mainte-
nance schedule.

Keep the tires inflated at the correct pres-
sure. Low pressure will increase tire wear and
waste fuel.

Keep the front wheels in correct alignment.
Improper alignment will cause not only tire
wear but also lower fuel economy.

Air conditioner operation lowers fuel
economy. Use the air conditioner only when
necessary.

When cruising at highway speeds, it is more
economical to use the air conditioner andleave the windows closed to reduce drag.
