BREAK-IN SCHEDULE
Starting and driving5-109

•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
serious 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) position. 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 CURB
OA:
Turn the wheels into the curb and
move the vehicle forward until the
curb side wheel gently touches the
curb.
• HEADED UPHILL WITH CURB
OB:
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
OC:
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 is
turned off while driving, the power
assist 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
harder to operate. Have the power
steering system checked. It is recom-
mended that you visit a NISSAN
dealer for this service.
The power steering system is designed to
provide power assist while driving to oper-
ate 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
5-112Starting and driving

light will illuminate. In a safe location, stop
the engine and push the ignition switch to
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, there will
be no power assist for the steering but you
will still have control of the vehicle. At this
time, greater steering effort is 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, accelerat-
ing or downshif ting. Abrupt braking
or accelerating 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
Starting and driving5-113

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
performance.
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, but
it 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 ve-
hicle 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, see “Tire and
Loading Information label” (P. 8-30).
– For additional information, see
“Wheels and tires” (P. 8-27).
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) in-
cludes 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 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 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 system then
operates normally but without anti-lock
assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the ve-
hicle checked. It is recommended that you
visit a NISSAN dealer for this service.
5-114Starting and driving

The Integrated Dynamics-control Module
is an electric control module that includes
the following functions:
• Intelligent Trace Control
• Intelligent Engine Brake
• Active Ride Control
INTELLIGENT TRACE CONTROL
(I-TC)
This system senses driving based on the
driver’s steering and acceleration/braking
patterns, and controls brake pressure at
individual wheels to aid tracing at corners
and help smooth vehicle response.
The I–TC can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, see “Vehicle information display”
(P. 2-17).
When the VDC OFF switch is used to turn off
the VDC system, the I–TC is also turned off.
If the Chassis Control System Error
warning message appears in the vehicle
information display, it may indicate that the
I–TC is not functioning properly. Have the
system checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
WARNING
The I–TC may not be effective depend-
ing on the driving condition. Always
drive carefully and attentively.
When the I–TC is operating, you may feel a
pulsation in the brake pedal and hear a
noise. This is normal and indicates that the
I–TC is operating properly.
Even if the I–TC is set to OFF, some func-
tions will remain on to assist the driver (for
example, avoidance scenes).
INTELLIGENT ENGINE BRAKE (I-EB)
The I–EB function adds subtle deceleration
by controlling the Continuously Variable
Transmission (CVT) gear ratio, depending
on the cornering condition calculated from
the driver's steering input and plural sen-
sors. This benefit is for easier traceability
and less workload of adjusting speed with
braking at corners.
The I–EB also enhances braking feel by
adding subtle deceleration with the CVT
gear ratio control according to the driver's
brake pedal operation. The I–EB can be set to ON (enabled) or OFF
(disabled) through the vehicle information
display “Settings” page. For additional infor-
mation, see “Vehicle information display”
(P. 2-17).
If the Chassis Control System Error
warning message appears in the vehicle
information display, it may indicate that the
I–EB is not functioning properly. Have the
system checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
WARNING
The I–EB may not be effective depend-
ing on driving conditions. Always drive
carefully and attentively.
When the I–EB is operating, the needle of the
tachometer will rise up and you may hear an
engine noise. This is normal and indicates
that the I–EB is operating properly.
INTEGRATED DYNAMICS-CONTROL
MODULE
5-118Starting and driving

ACTIVE RIDE CONTROL (ARC)
This system senses upper body motion
(based on wheel speed information) and
controls engine torque and four wheel
brake pressure. This will enhance ride com-
fort in effort to restrain uncomfortable up-
per body movement when passing over
undulated road surfaces. This system
comes into effect above 25 mph (40 km/h).
When the VDC OFF switch is used to turn off
the VDC system, the ARC is also turned off.
If the Chassis Control System Error
warning message appears in the vehicle
information display, it may indicate that the
ARC is not functioning properly. Have the
system checked as soon as possible. It is
recommended that you visit a NISSAN
dealer for this service.
When the ARC is operating, you may hear
noise and sense slight deceleration. This is
normal and indicates that the ARC is oper-
ating properly.The sonar (parking sensor) system 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 meter.
WARNING
• The sonar (parking sensor) system is
a convenience but it is not a substi-
tute 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 sonar (parking sensor) system
as contained in this section. The col-
ors of the corner sonar indicator and
the distance guide lines in the front/
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 pre-
vent contact with small or moving
objects. Always move slowly. The
system will not detect small objects
below the bumper, and may not de-
tect objects close to the bumper or
on the ground.

The blocked condition may also be caused
by objects such as ice, frost or dirt ob-
structing the sonar sensors.
Check for and remove objects obstructing
the area around the sonar sensors.
Do not attach stickers (including transpar-
ent material), install accessories or apply
additional paint near the sonar sensors.
Do not strike or damage the area around
the sonar sensors. It is recommended that
you visit a NISSAN dealer if the area around
the sonar sensors is damaged due to a
collision.FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
de-icer through the key hole. If the lock
becomes frozen, heat the key before in-
serting it into the key hole or use the re-
mote keyless entry function on the Intelli-
gent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C),
check the antifreeze to assure proper win-
ter protection. For additional information,
see “Engine cooling system” (P. 8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the bat-
tery fluid may freeze and damage the bat-
tery. To maintain maximum efficiency, the
battery should be checked regularly. For ad-
ditional information, see “Battery” (P. 8-14).
DRAINING OF COOLANT WATER
If the vehicle is to be lef t outside without
antifreeze, drain the cooling system, includ-
ing the engine block. Refill before operating
the vehicle. For additional information, see
“Changing engine coolant” (P. 8-5).
TIRE EQUIPMENT
1. SUMMER tires have a tread designed toprovide superior performance on dry
pavement. However, the performance of
these tires will be substantially reduced
in snowy and icy conditions. If you oper-
ate your vehicle on snowy or icy roads,
NISSAN recommends the use of MUD &
SNOW or ALL SEASON TIRES on all four
wheels. It is recommended that you visit
a NISSAN dealer for the tire type, size,
speed rating and availability information.
2. For additional traction on icy roads, studded tires may be used. However,
some U.S. states and Canadian prov-
inces prohibit their use. Check local,
state and provincial laws before install-
ing studded tires.
Skid and traction capabilities of studded
snow tires on wet or dry surfaces may be
poorer than that of non-studded snow
tires.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items
be carried in the vehicle during winter:
• A scraper and stiff-bristled brush to re- move ice and snow from the windows
and wiper blades.
