5.Use Cruise Control
∙ Using cruise control during highway driving 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 determine 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 cruis-
ing 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
effectively circulate the engine oil be-
fore driving.
∙ Your vehicle will reach its ideal oper- ating 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 pos-
sible.
∙ When entering a hot vehicle, opening the windows will help to reduce the
inside temperature faster, resulting in
reduced demand on your A/C sys-
tem. ∙ Keep your engine tuned up.
∙ Follow the recommended scheduled
maintenance.
∙ Keep the tires inflated to the correct pressure. Low tire pressure increases
tire wear and lowers fuel economy.
∙ Keep the wheels in correct alignment. Improper alignment increases tire wear
and lowers fuel economy.
∙ Use the recommended viscosity engine oil. For additional information, refer to
“Engine oil and oil filter recommenda-
tions” in the “Technical and consumer
information” section of this manual.

If any malfunction occurs in the AWD sys-
tem while the engine is running, messages
are displayed in the meter.If the AWD error warning message is dis-
played, there may be a malfunction in the
AWD system. Reduce vehicle speed and
have your vehicle checked. It is recom-
mended that you visit a NISSAN dealer as
soon as possible.The AWD high temperature message may
be displayed while trying to free a stuck
vehicle due to increased oil temperature.
The driving mode may change to 2-wheel
drive. If this message is displayed, stop the
vehicle with the engine idling, as soon as it
is safe to do so. Then if the message turns
off, you can continue driving.

equipped)
5-166Starting and driving

∙ If the tire size incorrect message isdisplayed while you are driving, pull
off the road in a safe area with the
engine idling. Check that all tire sizes
are the same, that the tire pressure is
correct and that the tires are not ex-
cessively worn.
∙ If a warning message continues to be displayed af ter the above operations,
have your vehicle checked as soon as
possible. It is recommended that you
visit a NISSAN dealer for this service.
WARNING
∙ Do not stop or park the vehicle overflammable materials such as dry
grass, waste paper or rags. They may
ignite and cause a fire. ∙ Safe parking procedures require that
both the parking brake be set and the
transmission placed into P (Park). Fail-
ure to do so could cause the vehicle to
move unexpectedly or roll away and
result in an accident. Make sure the
shif t lever has been pushed as far for-
ward as it can go and cannot be
moved without depressing the foot
brake pedal.
∙ Never leave the engine running while the vehicle is unattended.

PARKING/PARKING ON HILLS
5-168Starting and driving

∙ Do not leave children unattended in-side the vehicle. They could unknow-
ingly activate switches or controls or
make the vehicle move. Unattended
children could become involved in se-
rious accidents.
∙ To help avoid risk of injury or death through unintended operation of the
vehicle and/or its systems, do not
leave children, people who require the
assistance of others or pets unat-
tended in your vehicle. Additionally,
the temperature inside a closed ve-
hicle on a warm day can quickly be-
come high enough to cause a signifi-
cant risk of injury or death to people
and pets.
1. Firmly apply the parking brake.
2. Move the shif t lever to the P (Park) po- sition.
3. To help prevent the vehicle from rolling into traffic when parked on an incline, it
is a good practice to turn the wheels as
illustrated. ∙ HEADED DOWNHILL WITH CURBA:
Turn the wheels into the curb and
move the vehicle forward until the curb
side wheel gently touches the curb.
∙ HEADED UPHILL WITH CURB
B:
Turn the wheels away from the curb
and move the vehicle back until the
curb side wheel gently touches the
curb.
∙ HEADED UPHILL OR DOWNHILL, NO CURB
C:
Turn the wheels toward the side of the
road so the vehicle will move away
from the center of the road if it moves.
4. Place the ignition switch in the LOCK position.
WARNING
∙ If the engine is not running or isturned off while driving, the power as-
sist for the steering will not work.
Steering will be harder to operate.
∙ When the power steering warning light illuminates with the engine run-
ning, there will be no power assist for
the steering. You will still have control
of the vehicle, but the steering will be
much harder to operate. Have the
power steering system checked. It is
recommended that you visit a NISSAN
dealer for this service.
The power steering system is designed to
provide power assistance while driving to
operate the steering wheel with light force.
When the steering wheel is operated re-
peatedly or continuously while parking or
driving at a very low speed, the power as-
sist for the steering wheel will be reduced.
This is to prevent overheating of the power
steering system and protect it from getting
damaged. While the power assist is re-
duced, steering wheel operation will be-
come heavy. If the steering wheel opera-
tion is still performed, the power steering
may stop and the power steering warning
POWER STEERING

light will illuminate. In a safe location, stop
the engine and place the ignition switch in
the OFF position. The temperature of the
power steering system will go down af ter a
period of time and the power assist level
will return to normal af ter starting the en-
gine. The power steering warning light will
go off. Avoid repeating such steering wheel
operations that could cause the power
steering system to overheat.
You may hear a noise from the front of the
vehicle when the steering wheel is oper-
ated. This is a normal operational noise
and is not a malfunction.
If the power steering warning light illumi-
nates while the engine is running, it may
indicate the power steering system is not
functioning properly and may need servic-
ing. Have the power steering system
checked. It is recommended that you visit a
NISSAN dealer for this service.
When the power steering warning light illu-
minates with the engine running, the
power assist for the steering will cease op-
eration but you will still have control of the
vehicle. At this time, greater steering efforts
are required to operate the steering wheel,
especially in sharp turns and at low speeds.The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
BRAKE PRECAUTIONS
Vacuum assisted brakes
The 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 pres-
sure on the brake pedal will be required to
stop the vehicle and stopping distance will
be longer.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This will overheat the brakes,
wear out the brake pads faster, and reduce
gas mileage.
To help reduce brake wear and to prevent
the brakes from overheating, reduce speed
and downshif t 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, accelerating or
downshif ting. Abrupt braking or ac-
celerating could cause the wheels to
skid and result in an accident.
∙ If the engine is not running or is turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.
Wet brakes
When the vehicle is washed or driven
through water, the brakes may get wet. As
a result, your braking distance will be lon-
ger and the vehicle may pull to one side
during braking.
To dry the brakes, drive the vehicle at a safe
speed while lightly pressing 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.
BRAKE SYSTEM
5-170Starting and driving

Parking brake break-in
Break 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 perfor-
mance.
This procedure is described in the vehicle
service manual. It is recommended that
you visit a NISSAN dealer for this service.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
∙ The ABS is a sophisticated device, butit cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain ve-
hicle control during braking on slip-
pery surfaces. Remember that stop-
ping distances on slippery surfaces
will be longer than on normal sur-
faces even with ABS. Stopping dis-
tances may also be longer on rough,
gravel or snow covered roads, or if you
are using tire chains. Always maintain
a safe distance from the vehicle in
front of you. Ultimately, the driver is
responsible for safety. ∙ Tire type and condition may also af-
fect braking effectiveness.
– When replacing tires, install the specified size of tires on all four
wheels.
– When installing a spare tire, make sure that it is the proper size and
type as specified on the Tire and
Loading Information label. For ad-
ditional information, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
The ABS controls the brakes so the wheels
do not lock during hard braking or when
braking on slippery surfaces. The system
detects the rotation speed at each wheel
and varies the brake fluid pressure to pre-
vent each wheel from locking and sliding.
By preventing each wheel from locking, the
system helps the driver maintain steering
control and helps to minimize swerving
and spinning on slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
Anti-lock Braking System will operate to
prevent the wheels from locking up. Steer
the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping
distances.
Self-test feature
The Anti-lock Braking System (ABS) includes
electronic sensors, electric pumps, hydraulic
solenoids and 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 for-
ward 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 does not indicate a malfunction. If the
computer senses a malfunction, it switches
the ABS off and illuminates the ABS warning
light on the instrument panel. The brake sys-
tem then operates normally but without
anti-lock assistance.
Starting and driving5-171

WARNING
∙ Never rely solely on the hill start assistsystem to prevent the vehicle from
moving backward on a hill. Always
drive carefully and attentively. De-
press the brake pedal when the ve-
hicle is stopped on a steep hill. Be es-
pecially careful when stopped on a hill
on frozen or muddy roads. Failure to
prevent the vehicle from rolling back-
wards may result in a loss of control of
the vehicle and possible serious injury
or death.
∙ The hill start assist system is not de- signed to hold the vehicle at a stand-
still on a hill. Depress the brake pedal
when the vehicle is stopped on a
steep hill. Failure to do so may cause
the vehicle to roll backwards and may
result in a collision or serious personal
injury.
∙ The hill start assist system may not prevent the vehicle from rolling back-
wards on a hill under all load or road
conditions. Always be prepared to de-
press the brake pedal to prevent the
vehicle from rolling backwards. Fail-
ure to do so may result in a collision or
serious personal injury. When the vehicle is stopped on a hill, the hill
start assist system automatically keeps
the brakes applied to help prevent the ve-
hicle from rolling backward in the time it
takes the driver to release the brake pedal
and apply the accelerator.
The hill start assist system will operate au-
tomatically under the following conditions:
∙ The transmission is shif ted to a forward or reverse gear.
∙ The vehicle is stopped completely on a hill by applying the brake. The maxi-
mum holding time is 2 seconds. Af ter
2 seconds the vehicle will begin to roll
back and the hill start assist system will
stop operating completely.
The hill start assist system will not operate
when the shif t lever is placed in the N (Neu-
tral) or P (Park) position or on a flat and level
road. The RSS sounds a tone to inform the driver
of obstacles near the bumper.
When the “DISPLAY” key is on, the sonar
view will automatically appear in the
touch-screen display. An additional view of
the sonar status will appear in the vehicle
information display for reference.

equipped)
5-176Starting and driving

WARNING
∙ The RSS is a convenience but it is not asubstitute for proper parking.
∙ The driver is always responsible for safety during parking and other ma-
neuvers. Always look around and
check that it is safe to do so before
parking.
∙ Read and understand the limitations of the RSS as contained in this section.
The colors of the corner sonar indica-
tor and the distance guide lines in the
rear view indicate different distances
to the object.
∙ Inclement weather or ultrasonic sources such as an automatic car
wash, a truck’s compressed-air
brakes or a pneumatic drill may affect
the function of the system; this may
include reduced performance or a
false activation.
∙ This function is designed as an aid to the driver in detecting large station-
ary objects to help avoid damaging
the vehicle. ∙ The system is not designed to prevent
contact with small or moving objects.
Always move slowly. The system will
not detect small objects below the
bumper, and may not detect objects
close to the bumper or on the ground.
∙ The system may not detect the fol- lowing objects: fluff y objects such as
snow, cloth, cotton, glass, wool, etc.;
thin objects such as rope, wire and
chain, etc.; or wedge-shaped objects.
If your vehicle sustains damage to the
bumper fascia, leaving it misaligned or
bent, the sensing zone may be altered
causing inaccurate measurement of ob-
stacles or false alarms.
CAUTION
∙ Excessive noise (such as audio system volume or an open vehicle window)
will interfere with the tone and it may
not be heard. ∙ Keep the sonar sensors (located on
the bumper fascia) free from snow, ice
and large accumulations of dirt. Do
not clean the sensors with sharp ob-
jects. If the sensors are covered, the
accuracy of the sonar function will be
diminished.
SYSTEM OPERATION
The system informs with a visual and au-
dible alert of rear obstacles when the shif t
lever is in the R (Reverse) position.
