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

RAB SYSTEM LIMITATIONS
WARNING
Listed below are the system limita-
tions for the RAB system. Failure to
follow the warnings and instructions
for proper use of the RAB system
could result in serious injury or
death.
.When the vehicle approaches an
obstacle while the accelerator or
brake pedal is depressed, the
function may not operate or the
start of the operation may be
delayed. The RAB system may
not operate or may not perform
sufficiently due to vehicle condi-
tions, driving conditions, the traf-
fic environment, the weather,
road surface conditions, etc. Do
not wait for the system to oper-
ate. Operate the brake pedal by
yourself as soon as necessary.
. If it is necessary to override RAB
operation, strongly press the ac-
celerator pedal.
. Always check your surroundings
and turn to check what is behind
you before and while backing up.
The RAB system detects station- ary objects behind the vehicle.
The RAB system does not detect
the following objects:
— Moving objects
— Low objects
— Narrow objects
— Wedge-shaped objects
— Complex-shaped objects
— Multiple object in close
— Objects close to the bumper
(less than approximately 1 ft
[30 cm])
— Objects that suddenly appear
— Thin objects such as rope, wire, chain, etc.
. The RAB system may not operate
for pedestrians or animals.
. The RAB system may not operate
for the following obstacles:
— Obstacles located high off the
ground
— Obstacles in a position offset from your vehicle
— Obstacles, such as spongy materials or snow, that have
soft outer surfaces and can
easily absorb a sound wave .
The RAB system may not operate
in the following conditions:
— There is rain, snow, ice, dirt,
etc., attached to the sonar
sensors.
— A loud sound is heard in the area around the vehicle.
— The surface of the obstacle is diagonal to the rear of the
vehicle.
— The sonar sensors or the area around them are extremely
hot or cold.
. The RAB system may uninten-
tionally operate in the following
conditions:
— There is overgrown grass in
the area around the vehicle.
— There is a structure (e.g., a wall, toll gate equipment, a
narrow tunnel, a parking lot
gate) near the side of the
vehicle.
— There are bumps, protrusions, or manhole covers on the
road surface.
— The vehicle is driving through a draped flag or a curtain.

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
Starting and driving5-143
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
VEHICLE DYNAMIC CONTROL (VDC) SYSTEM

illuminates (for 4WD models).
See “Vehicle Dynamic Control (VDC) warn-
ing light” (P.2-18) and “Vehicle Dynamic
Control (VDC) off indicator light” (P.2-18).
The computer has a built-in diagnostic
feature that tests the system each time
you start the engine and move the vehicle
forward or in reverse at a slow speed.
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 a malfunction.
WARNING
.The VDC system is designed to
help improve driving stability but
does not prevent accidents due
to abrupt steering operation at
high speeds or by careless or
dangerous driving techniques.
Reduce vehicle speed and be
especially careful when driving
and cornering on slippery sur-
faces and always drive carefully.
. Do not modify the vehicle’s sus-
pension. If suspension parts such
as shock absorbers, struts,
springs, stabilizer bars, bushings
and wheels are not NISSAN re-
commended for your vehicle or are extremely deteriorated, the
VDC system may not operate
properly. This could adversely
affect vehicle handling perfor-
mance, and the VDC warning light
may illuminate.
. If brake related parts such as
brake pads, rotors and calipers
are not NISSAN recommended or
are extremely deteriorated, the
VDC system may not operate
properly and the VDC warning
light
may illuminate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely in-
clined surfaces such as higher
banked corners, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate. Do not drive on these types
of roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the VDC warn-
ing light
may illuminate. This
is not a malfunction. Restart the
engine after driving onto a stable
surface. .
If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not
operate properly and the VDC
warning light
may illuminate.
. The VDC system is not a substi-
tute for winter tires or tire chains
on a snow covered road.

Extended storage fuse switch (if so
equipped)
To reduce battery drain, the extended
storage fuse switch comes from the
factory switched off. Prior to delivery of
your vehicle, the switch is pushed in
(switched on) and should always remain
on.
If the extended storage fuse switch is not
pushed in (switched on), the “Shipping
Mode On, Push Storage Fuse” warning
may appear on the vehicle information
display (if so equipped). See “Vehicle
information display” (P.2-19).
If any electrical equipment does not
operate, remove the extended storagefuse switch and check for an open fuse.
NOTE:
If the extended storage fuse switch
malfunctions or if the fuse is open, it is
not necessary to replace the switch. In
this case, remove the extended storage
fuse switch and replace it with a new
fuse of the same rating.
How to remove the extended storage
fuse switch:
1. To remove the extended storage fuse
switch, be sure the ignition switch is in
the OFF or LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabsfound on
each side of the storage fuse switch.
5. Pull the storage fuse switch straight out from the fuse box
.
CAUTION
Be careful not to allow children to
swallow the battery and removed
parts.

Pre-towing tips
.Be certain your vehicle maintains a
level position when a loaded or un-
loaded trailer is hitched. Do not drive
the vehicle if it has an abnormal nose-
up or nose-down condition; check for
improper tongue load, overload, worn
suspension or other possible causes
of either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center
of gravity low.
. Load the trailer so approximately 60%
of the trailer load is in the front half
and 40% is in the back half. Also make
sure the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light op-
eration, and trailer wheel lug nuts
every time you attach a trailer to the
vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required
clearance is known.
Trailer towing tips
In order to gain skill and an understand-
ing of the vehicle’s behavior, you should
practice turning, stopping and backing up
in an area which is free from traffic.
Steering stability, and braking perfor-
mance will be somewhat different than
under normal driving conditions.
.Always secure items in the trailer to
prevent load shift while driving.
. Lock the trailer hitch coupler with a
pin or lock to prevent the coupler from
inadvertently becoming unlatched.
. Avoid abrupt starts, acceleration or
stops.
. Avoid sharp turns or lane changes.
. Always drive your vehicle at a moder-
ate speed. Some states or provinces
have specific speed limits for vehicles
that are towing trailers. Obey the local
speed limits.
. When backing up, hold the bottom of
the steering wheel with one hand.
Move your hand in the direction in
which you want the trailer to go. Make
small corrections and back up slowly.
If possible, have someone guide you
when you are backing up.
Always block the wheels on both vehicle
and trailer when parking. Parking on a
slope is not recommended; however, if you must do so:
CAUTION
If you move the shift lever to the P
(Park) position before blocking the
wheels and applying the parking
brake, transmission damage could
occur.
1. Apply and hold the brake pedal.
2. Have someone place blocks on the downhill side of the vehicle and trailer
wheels.
3. After the wheel blocks are in place, slowly release the brake pedal until
the blocks absorb the vehicle load.
4. Apply the parking brake.
5. Shift the transmission into P (Park).
6. Four-Wheel Drive (4WD) models:
Make sure that the 4WD shift switch is
engaged in the AUTO, 4HI or 4LO
position and the Automatic Transmis-
sion (AT) park warning light is turned
off.
7. Turn off the engine.
To drive away:
1. Apply and hold the brake pedal.
