or roll away and result in serious per-
sonal injury or property damage.
If the ignition switch is turned to OFF or ACC for
any reason while the vehicle is in R (Reverse), N
(Neutral), or any D (Drive) position, the key
cannot be turned to LOCK and be removed from
the ignition switch. Additionally, the selector
lever cannot be moved to R (Reverse) from N
(Neutral) or any D (Drive) position for about 3
minutes after the ignition switch is turned to the
ACC or OFF position. The selector lever can be
moved from R (Reverse) to P (Park) with the key
in the OFF or ACC position. If this occurs,
perform the following steps:
1. Apply the parking brake when the vehicle is
stopped.
2. Turn the key to ON.
3. Depress the foot brake pedal if the vehicle is
in the N (Neutral) or any D (Drive) position.
4. If necessary, move the selector lever to P
(Park) or N (Neutral) to restart the vehicle (P
is preferred) or move the selector lever to P
(Park) to park the vehicle.
5. Turn the ignition switch to LOCK to remove
the key.P (Park):
Use this shift position when the vehicle is parked
or when starting the engine. Make sure the
vehicle is completely stopped. For maximum
safety, depress the brake pedal, then move the
lever to the P (Park) position.The brake pedal
must be depressed any time the selector
lever is moved to P (Park).Apply the parking
brake. When parking on a hill, apply the parking
brake first, then move the lever to the P (Park)
position.
CAUTION
Use this position only when the vehicle
is completely stopped.
R (Reverse):
Use this position to back up. Always be sure the
vehicle is completely stopped when selecting R
(Reverse).The brake pedal must be de-
pressed to move the selector lever from P
(Park) to R (Reverse).
The selector lever can be moved to R (Reverse)
from any of the D (Drive) positions within 3
minutes after the ignition switch is turned to the
ACC or OFF position.N (Neutral):
Neither forward or reverse gear is engaged. The
engine can be started in this position. You may
shift to N (Neutral) and restart a stalled engine
while the vehicle is moving.
D (Drive):
Use this position for all normal forward driving.
Manual shift modeWhen the selector lever is shifted from D to the
manual shift gate with the vehicle stopped or
while driving, the transmission enters the manual
shift mode. Shift ranges can be selected manu-
ally.
In the manual shift mode, the shift range is
displayed on the position indicator in the meter.
Shift ranges up or down one by one as follows:M1→
←M2→
←M3→
←M4→
←M5→
←M6M6 (Sixth):
Use this position for all normal forward driving.
M5 (Fifth):
For driving up or down long slopes where engine
braking would be advantageous.

M4 (Fourth), M3 (Third) and M2 (Second):
Use for hill climbing or engine braking on down-
hill grades.
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.

Remember not to drive at high speeds for
extended periods of time in lower than M6
range. This reduces fuel economy.

When shifting up, move the selector lever to
the + (up) side. (Shifts to higher range.)

When shifting down, move the selector lever
to the − (down) side. (Shifts to lower range.)

Moving the selector lever to the same side
twice will shift the ranges in succession.
However, if this motion is rapidly done, the
second shifting may not be completed prop-
erly.

In the manual shift mode, the transmis-
sion automatically shifts down to M1
(First) before the vehicle comes to a
stop. When accelerating again, it is nec-
essary to shift up to the desired range.

When canceling the manual shift mode, re-
turn the selector lever to the D position. Thetransmission returns to the normal driving
mode.

In the manual shift mode, the transmis-
sion may not shift to the selected gear.
This helps maintain driving performance
and reduces the chance of vehicle dam-
age or loss of control.

When the CVT fluid temperature is extremely
low, the manual shift mode may not work and
automatically shift as a drive mode. This is not
a malfunction. In this case, return the selector
lever to D range and drive for a while and then
shift to the manual shift mode.

When the CVT fluid temperature is high, the
shift range may upshift in lower rpm than
usual. This is not a malfunction.
Shift lock releaseIf the battery is discharged, the selector lever
may not be moved from the P (Park) position
even with the brake pedal depressed.
To move the selector lever, push the shift lock
release button while depressing the foot brake
and applying the parking brake. The selector
lever can be moved to N (Neutral). This allows
the vehicle to be moved if the battery is dis-
charged, after releasing the parking brake.
If the battery is discharged in N (Neutral), D
(Drive) or Manual shift mode, the selector lever
may not be moved to the P (Park) position.

If it is necessary to park the vehicle, push the
shift lock release button, then move the selector
lever to the P (Park).
To push the shift lock release button, follow the
procedure as illustrated.
If the lever cannot be moved out of P (Park), have
a NISSAN dealer check the CVT system as soon
as possible.
WARNING

If the selector lever 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. Malfunctioning stop
lights could cause an accident injur-
ing yourself and others.

Do not park the vehicle without shift-
ing to the P (Park) position.Accelerator downshift
— In D position —For passing or hill climbing, fully depress the
accelerator pedal to the floor. This shifts the
transmission down into the lower gear, depend-ing 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 switch to the OFF
position and wait for 10 seconds. Then turn
the switch back to the ONposition. The
vehicle should return to its normal operat-ing condition. If it does not return to its
normal operating condition, have a
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. 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 SET/COAST switch.
b) Push and hold the RESUME/
ACCELERATOR set switch. When the ve-
hicle attains the speed you desire, release the
switch.
c) Push, then quickly release the RESUME/
ACCELERATOR 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 SET/
COAST switch and release it.
b) Push and hold the SET/COAST switch. Re-
lease the switch when the vehicle slows
down to the desired speed.
c) Push, then quickly release the SET/COAST
switch. Each time you do this, the set speed
will decrease by about 1 MPH (1.6 km/h).To resume the preset speed,push and re-
lease the RESUME/ACCELERATOR set switch.
The vehicle will resume 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 ob-
tain maximum engine performance and
ensure the future reliability and
economy of your new vehicle. Failure to
follow these recommendations may re-
sult in shortened engine life and re-
duced engine performance.

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

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.
WARNING
A vehicle equipped with AWD (All-
Wheel Drive) should never be tested
using a two wheel dynamometer, similar
to the dynamometers used by some
states for emissions testing, or similar
equipment. Make sure you inform the
test facility personnel that your vehicle
is an AWD equipped vehicle before it is
placed on a dynamometer. Failure to do
so may result in transmission damage

over approximately 10 km/h (6 MPH). The AWD LOCK indicator light does not go off.
LOCK mode will change to AUTO mode automatically when the vehicle has been driven for a high speed. The
AWD LOCK indicator light goes off.
*3: LOCK mode will automatically be cancelled when the ignition switch is turned to the OFF position.
If the AWD LOCK switch is operated while accelerating or decelerating, or if the ignition switch
is turned off, you may feel a jerk. This is normal.

The oil temperature of power train parts will increase if the vehicle is continuously operated under
conditions where the difference in rotation between the front and rear wheels is large (wheel slip),
such as when driving the vehicle on rough roads through sand, mud or freeing a stuck vehicle. In
these cases, the AWD warning light blinks rapidly and the AWD mode changes to 2WD condition
to protect the power train parts. If you stop driving with the engine idling and wait until the warning
light stops blinking, the AWD returns to the AUTO mode.
WARNING

Do not place an AWD equipped ve-
hicle on a two wheel dynamometer or
raise two wheels off the ground and
shift the transmission to any D (drive)
or R (reverse) position. Doing so may
result in transmission damage or un-
expected vehicle movement which
could result in serious vehicle dam-
age or personal injury.

When driving straight, shift the AWD
lock switch to AUTO. Do not operate
the AWD lock switch when making a
turn or backing up.

Do not operate the AWD lock switch
with the front wheel spinning.

Engine idling speed is high while
warming up the engine. Be especially
careful when starting or driving on
slippery surfaces with the AWD lock
switch set in AUTO or LOCK.

When turning the vehicle in LOCK
mode on paved roads, you may feel

a braking effect. This is a normal
condition of the AWD model.
AWD WARNING LIGHTThe AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is turned to ON. It turns off soon
after the engine is started.If any malfunction occurs in the AWD system
when the ignition switch is ON, the warning light
will remain illuminated.
High-temperature power-train oil due to continu-
ous operation of the vehicle to free a stuck
vehicle makes the warning light blink rapidly
(about twice per second). The driving mode may
change to 2 wheel drive condition. AUTO mode
may change to LOCK mode before the warning
light blinks. This is normal. If the warning light
blinks rapidly during operation, stop the vehicle
with the engine idling in a safe place immedi-
ately. Then if the light goes off after a while, you
can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning light
blink slowly (about once per two seconds). Pull
off the road in a safe area, and idle the engine.
Check that all tire sizes are the same, tire
pressure is correct and tires are not worn.
WARNING
Do not attempt to test an AWD
equipped vehicle with two wheels on a
two wheel dynamometer and the other
two wheels raised. Doing so may result

WARNING

Do not stop or park the vehicle over
flammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire.

Never leave the engine running while
the vehicle is unattended.

Do not leave children unattended in-
side the vehicle.1. Firmly apply the parking brake.
2. Move the selector lever to the P (Park) posi-
tion.
WARNING

Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park).
Failure to do so could cause the ve-
hicle to move unexpectedly or roll
away and result in an accident.

Make sure the selector lever has
been pushed as far forward as it can
go and cannot be moved without de-
pressing the button at the end of the
lever.
3. To help prevent the vehicle from rolling into
the street when parked on a sloping drive
way, it is a good practice to turn the wheels
as illustrated.

4. Turn the ignition switch to the LOCK position
and remove the key.The power assisted steering is designed to use
a hydraulic pump, driven by the engine, to assist
steering.
If the engine stops or drive belt breaks, you will
still have control of the vehicle. However, much
greater steering effort is needed, especially in
sharp turns or at low speeds.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be much harder to operate.
BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakeThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.Parking brake break-inBreak in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the

best braking performance.
This procedure is described in the vehicle ser-
vice manual and can be performed by a NISSAN
dealer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
increases wear on the brake linings and pads,
and reduces gas mileage.
To help save the brakes and to prevent the
brakes from overheating, reduce speed and
downshift to a lower gear before going down a
slope or long grade. Overheated brakes may
reduce braking performance and could result in
loss of vehicle control.
WARNING

While driving on a slippery surface,
be careful when braking, accelerat-
ing or downshifting. Abrupt braking
or accelerating could cause the
wheels to skid and result in an acci-
dent.

If the engine is not running or is
turned off while driving, the powerassist for the brakes will not work.
Braking will be harder.
ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
at each wheel so the wheels will not lock when
braking abruptly or when braking on slippery
surfaces. The system detects the rotation speed
at each wheel and varies the brake fluid pressure
to prevent each wheel from locking and sliding.
By preventing wheel lockup, the system helps
the driver maintain steering control and helps to
minimize swerving and spinning on slippery sur-
faces.Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Normal operationThe anti-lock brake system will not operate atspeeds below 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary according to road conditions.) When the
anti-lock system senses that one or more wheels
are close to locking up, the actuator (under the
hood) rapidly applies and releases hydraulic
pressure (like pumping the brakes very quickly).
While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the ABS operation
may indicate that road conditions are hazardous
and extra care is required while driving.
Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps and hydraulic solenoids
controlled by a computer. The computer has a
built-in diagnostic feature that tests the system
each time you start the engine and move the
vehicle at a low speed in forward or reverse.
When the self-test occurs, you may hear a
“clunk” noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication of
any malfunction. If the computer senses any
malfunction, it switches the anti-lock brake sys-
tem off and turns on the ABS warning light on
the instrument panel. The brake system then
operates normally, but without anti-lock assis-
tance.
