Vehicle-to-vehicle distance control
mode limitations
WARNING
Listed below are the system limita-
tions for the ICC system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
.The system is primarily intended
for use on straight, dry, open
roads with light traffic. It is not
advisable to use the system in
city traffic or congested areas.
. This system will not adapt auto-
matically to road conditions. This
system should be used in evenly
flowing traffic. Do not use the
system on roads with sharp
curves, or on icy roads, in heavy
rain or in fog.
. As there is a performance limit to
the distance control function,
never rely solely on the ICC sys-
tem. This system does not correct
careless, inattentive or absent-
minded driving, or overcome
poor visibility in rain, fog, or other
bad weather. Decelerate the ve-
hicle speed by depressing the brake pedal, depending on the
distance to the vehicle ahead
and the surrounding circum-
stances in order to maintain a
safe distance between vehicles.
. If the vehicle ahead comes to a
stop, the vehicle decelerates to a
standstill within the limitations of
the system. The system will can-
cel once it judges that the vehicle
has come to a standstill and
sound a warning chime. To pre-
vent the vehicle from moving, the
driver must depress the brake
pedal.
. Always pay attention to the op-
eration of the vehicle and be
ready to manually control the
proper following distance. The
vehicle-to-vehicle distance con-
trol mode of the ICC system may
not be able to maintain the se-
lected distance between vehicles
(following distance) or selected
vehicle speed under some cir-
cumstances.
. The system may not detect the
vehicle in front of you in certain
road or weather conditions. To
avoid accidents, never use the ICC
system under the following con-
ditions: — On roads where the traffic is
heavy or there are sharp
curves
— On slippery road surfaces such as on ice or snow, etc.
— During bad weather (rain, fog, snow, etc.)
— When rain, snow or dirt adhere to the system sensor
— On steep downhill roads (the vehicle may go beyond the set
vehicle speed and frequent
braking may result in over-
heating the brakes)
— On repeated uphill and down- hill roads
— When traffic conditions make it difficult to keep a proper
distance between vehicles be-
cause of frequent accelera-
tion or deceleration
. Do not use the ICC system if you
are towing a trailer. The system
may not detect a vehicle ahead.
. In some road or traffic conditions,
a vehicle or object can unexpect-
edly come into the sensor detec-
tion zone and cause automatic
braking. You may need to control

SONAR LIMITATIONS
WARNING
Listed below are the system limita-
tions for the sonar system. Failure to
operate the vehicle in accordance
with these system limitations could
result in serious injury or death.
. Read and understand the limita-
tions of the sonar system as
contained in this section. Incle-
ment weather may affect the function of the sonar system; this
may include reduced perfor-
mance or a false activation.
. The sonar system is deactivated
at speeds above 6 MPH (10 km/h).
It is reactivated at lower speeds.
. 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 sonar
system; this may include reduced
performance or a false activation.
. The sonar 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
or on the ground.
. The sonar system may not detect
the following objects: fluffy ob-
jects such as snow, cloth, cotton,

the road surface.
— When the vehicle drives through a draped flag or a
curtain.
— When there is an accumula- tion of snow or ice behind the
vehicle.

BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking
force than a conventional brake booster
even with light pedal force.
WARNING
The Brake Assist is only an aid to
assist braking operation and is not a
collision warning or avoidance de-
vice. It is the driver’s responsibility to
stay alert, drive safely and be in
control of the vehicle at all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System
(ABS) is a sophisticated device,
but it cannot prevent accidents
resulting from careless or dan-
gerous driving techniques. It can
help maintain vehicle control dur-
ing braking on slippery surfaces.
Remember that stopping dis-
tances on slippery surfaces will
be longer than on normal sur- faces even with ABS. Stopping
distances 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
affect 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 Informa-
tion label. See “Tire and load-
ing information label” (P.10-
13).
— For detailed information, see “Wheels and tires” (P.8-28).
The Anti-lock Braking System (ABS) con-
trols 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 prevent each
wheel from locking and sliding. By pre-
venting 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 ABS 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 ABS includes electronic sensors, elec-
tric 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 malfunc-
tion. If the computer senses a malfunc-
tion, it switches the ABS off and

BRAKE ASSIST

5-144Starting and driving
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
vehicle checked. It is recommended you
visit a NISSAN dealer for this service.
Normal operation
The ABS operates at speeds above 3 to 6
MPH (5 to 10 km/h). The speed varies
according to road conditions.
When the ABS senses that one or more
wheels are close to locking up, the
actuator rapidly applies and releases
hydraulic pressure. This action is similar
to pumping the brakes very quickly. You
may feel a pulsation in the brake pedal
and hear a noise from under the hood or
feel a vibration from the actuator when it
is operating. This is normal and indicates
that the ABS is operating properly. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care
is required while driving.The Vehicle Dynamic Control (VDC) sys-
tem uses various sensors to monitor
driver inputs and vehicle motion. Under
certain driving conditions, the VDC sys-
tem helps to perform the following func-
tions.
.
Controls brake pressure to reduce
wheel slip on one slipping drive wheel
so power is transferred to a non
slipping drive wheel on the same axle.
. Controls brake pressure and engine
output to reduce drive wheel slip
based on vehicle speed (traction con-
trol function).
. Controls brake pressure at individual
wheels and engine output to help the
driver maintain control of the vehicle
in the following conditions:
— understeer (vehicle tends to not
follow the steered path despite
increased steering input)
— oversteer (vehicle tends to spin due to certain road or driving condi-
tions).
The VDC system can help the driver to
maintain control of the vehicle, but it
cannot prevent loss of vehicle control in
all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel
flashes so note the following: .
The road may be slippery or the
system may determine some action
is required to help keep the vehicle on
the steered path.
. You may feel a pulsation in the brake
pedal and hear a noise or vibration
from under the hood. This is normal
and indicates that the VDC system is
working properly.
. Adjust your speed and driving to the
road conditions.
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically turns off.
The VDC OFF switch is used to turn off the
VDC system. The VDC off indicator
illuminates to indicate the VDC system is
off. When the VDC switch is used to turn
off the system, the VDC system still
operates to prevent one drive wheel from
slipping by transferring power to a non
slipping drive wheel. The VDC warning
light
flashes if this occurs. All other
VDC functions are off, and the VDC
warning light
will not flash. The VDC
system is automatically reset to on when
the ignition switch is placed in the OFF
position then back to the ON position.
When the 4L position is selected with the
4WD shift switch, the VDC system is
disabled and the VDC off indicator light

could affect the proper operation
of the TPMS.
. Do not inject any tire liquid or
aerosol tire sealant into the tires,
as this may cause a malfunction
of the tire pressure sensors.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instruc-
tions below.
Stopping the vehicle
1. Safely move the vehicle off the road
and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to
the P (Park) position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to signal professional road assis-
tance personnel that you need assis-
tance.
6. Have all passengers get out of the vehicle and stand in a safe place, away
from traffic and clear of the vehicle.
WARNING
.Make sure the parking brake is
securely applied and the auto-
matic transmission is in the P
(Park) position.
. Never change tires when the ve-
hicle is on a slope, ice or slippery
areas. This is hazardous.
. Never change tires if oncoming
traffic is close to your vehicle.
Wait for professional road assis-
tance.
MCE0001A
Blocking wheels
Place suitable blocksat both the front
and back of the wheel diagonally oppo-
site the flat tire to prevent the vehicle
from moving when it is jacked up.
WARNING
Be sure to block the wheel as the
vehicle may move and result in
personal injury.

8-38Do-it-yourself
the same size and you are only
replacing 2 of the 4 tires, install
the new tires on the rear axle.
Placing new tires on the front
axle may cause loss of vehicle
control in some driving condi-
tions and cause an accident and
personal injury.
. If the wheels are changed for any
reason, always replace with
wheels which have the same off-
set dimension. Wheels of a differ-
ent off-set could cause prema-
ture tire wear, degrade vehicle
handling characteristics and/or
interference with the brake
discs/drums. Such interference
can lead to decreased braking
efficiency and/or early brake
pad/shoe wear. See “Wheels and
tires” (P.10-9) for wheel off-set
dimensions.
. Since the spare tire is not
equipped with the TPMS, when a
spare tire is mounted or a wheel
is replaced, the TPMS will not
function and the low tire pressure
warning light will flash for ap-
proximately 1 minute. The light
will remain on after 1 minute.
Have your tires replaced and/or
TPMS system reset as soon as possible. It is recommended you
visit a NISSAN dealer for these
services.
. Replacing tires with those not
originally specified by NISSAN
could affect the proper operation
of the TPMS.
. The TPMS sensor may be da-
maged if it is not handled cor-
rectly. Be careful when handling
the TPMS sensor.
. When replacing the TPMS sensor,
the ID registration may be re-
quired. It is recommended you
visit a NISSAN dealer for ID regis-
tration.
. Do not use a valve stem cap that
is not specified by NISSAN. The
valve stem cap may become
stuck.
. Be sure that the valve stem caps
are correctly fitted. Otherwise the
valve may be clogged up with dirt
and cause a malfunction or loss
of pressure.
. Do not install a damaged or
deformed wheel or tire even if it
has been repaired. Such wheels
or tires could have structural
damage and could fail without
warning. .
The use of retread tire is not
recommended.
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or
“Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
Four-Wheel Drive (4WD) models
CAUTION
.Always use tires of the same type,
size, brand, construction (bias,
bias-belted or radial), and tread
pattern on all four wheels. Failure
to do so may result in a circum-
ference difference between tires
on the front and rear axles which
will cause excessive tire wear and
may damage the transmission,
transfer case and differential
gears.
. ONLY use spare tires specified for
the 4WD model.
If excessive tire wear is found, it is
recommended that all four tires be re-
placed with tires of the same size, brand,
