The VDC system will be disabled and the VDC
light will illuminate when the electronic locking
rear differential (E-lock) system switch (if so
equipped) is turned on and the E-lock system is
engaged. If the E-lock system disengages or the
switch is turned off, the VDC system will be
enabled and the VDC light will turn off.
AUDIBLE REMINDERS
Brake pad wear warning
The disc brake pads have audible wear warnings.
When a disc brake pad requires replacement, it
makes a high pitched scraping sound when the
vehicle is in motion, whether or not the brake
pedal is depressed. Have the brakes checked as
soon as possible if the warning sound is heard.
Key reminder chime
A chime sounds if the driver’s door is opened
while the key is left in the ignition switch. Remove
the key and take it with you when leaving the
vehicle.
Light reminder chime
With the ignition switch placed in the OFF posi-
tion, a chime sounds when the driver’s door is
opened if the headlights or parking lights are on.
Turn the headlight control switch off before leav-
ing the vehicle.Your vehicle may have two types of security sys-
tems:
● Vehicle security system (if so equipped)
● NISSAN Vehicle Immobilizer System (if so
equipped)
VEHICLE SECURITY SYSTEM (if so
equipped)
The vehicle security system provides visual and
audible alarm signals if someone opens the doors
when the system is armed. It is not, however, a
motion detection-type system that activates
when a vehicle is moved or when a vibration
occurs. The system helps deter vehicle theft but cannot
prevent it, nor can it prevent the theft of interior or
exterior vehicle components in all situations. Al-
ways secure your vehicle even if parking for a
brief period. Never leave your keys in the ignition,
and always lock the vehicle when unattended. Be
aware of your surroundings, and park in secure,
well-lit areas whenever possible.
Many devices offering additional protection, such
as component locks, identification markers, and
tracking systems, are available at auto supply
stores and specialty shops. Your NISSAN dealer
may also offer such equipment. Check with your
insurance company to see if you may be eligible
for discounts for various theft protection features.
How to arm the vehicle security
system
1. Close all windows.
(The system can be
armed even if the windows are open.)
2. Remove the key from the ignition switch.
3. Close all doors. Lock all doors. The doors can be locked with the key, power door lock
switch (if the door is opened, locked and
then closed) , or with the key fob.

WARNING
●Never rely solely on the hill descent
control system to control vehicle speed
when driving on steep downhill grades.
Always drive carefully when using the
hill descent control system and deceler-
ate the vehicle speed by depressing the
brake pedal if necessary. Be especially
careful when driving on frozen, muddy
or extremely steep downhill roads. Fail-
ure to control vehicle speed may result
in a loss of control of the vehicle and
possible serious injury or death. ●
The hill descent control may not control
the vehicle speed on a hill under all load
or road conditions. Always be prepared
to depress the brake pedal to control
vehicle speed. Failure to do so may re-
sult in a collision or serious personal
injury.
CAUTION
When the hill descent control system op-
erates continuously for a long time, the
temperature of the brake pads may in-
crease and the hill descent control system
may be temporarily disabled (the indicator
light will blink) . If the indicator light does
not come on continuously after blinking,
stop using the system.
The hill descent control system is designed to
reduce driver workload when going down steep
hills. The hill descent control system helps to
control vehicle speed so the driver can concen-
trate on steering the vehicle.
To activate the hill descent control system: ● the 4WD switch must be in the 4L position
and the vehicle speed must be under
15 MPH (25 km/h) or ●
the 4WD switch must be in the 4H position
and the vehicle speed must be under
21 MPH (35 km/h), and
● the hill descent control system switch must
be ON.
The hill descent control system on indicator light
will come on when the system is activated. Also,
the stop/tail lights illuminate while the hill descent
control system applies the brakes to control ve-
hicle speed.
If the accelerator or brake pedal is depressed
while the hill descent control system is on, the
system will stop operating temporarily. As soon
as the accelerator or brake pedal is released, the
hill descent control system begins to function
again if the hill descent control operating condi-
tions are fulfilled.
The hill descent control system on indicator light
blinks if the switch is on and all conditions for
system activation are not met or if the system
becomes disengaged for any reason.
To turn off the hill descent control system, push
the switch to the OFF position.
For additional information, refer to “Hill descent
control system on indicator light” in this section
and “Hill descent control system” in the “Starting
and driving” section of this manual.

The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, especially
in sharp turns and 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
harder to operate.The brake system has two separate hydraulic
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 pressure on the brake pedal will be
required to stop the vehicle and stopping dis-
tance 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
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, accelerating or
downshifting. Abrupt braking or accel-
erating 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 longer 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.
Parking brake break-in
Break-in the parking brake shoes whenever the
effect of the parking brake is weakened or when-
ever the parking brake shoes and/or drum/rotors
are replaced, in order to assure the best brake
performance.

When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly ap-
plies 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.
However, the pulsation may indicate that road
conditions are hazardous and extra care is re-
quired while driving.●
ABLS system uses automatic braking to
transfer power from a slipping drive wheel to
the wheel on the same axle with more trac-
tion. The ABLS system applies braking to
the slipping wheel, which helps redirect
power to the other wheel.
● On 4WD models the ABLS system operates
in both 4H and 4LO modes. If 4WD mode is
engaged, the ABLS system operates for
both drive axles. On 2WD vehicles, the
ABLS system operates on the drive axle
only.
● The ABLS system is always ON. In some
conditions, the system may automatically
turn the ABLS system off. If the system is
automatically turned off, normal brake func-
tion will continue. ABLS will function even
when the VDC system is turned OFF.
● The ABLS does not operate if both wheels
on a drive axle are slipping.WARNING
● The ABLS system helps provide in-
creased traction, but will not prevent
accidents due to abrupt steering opera-
tion or by careless driving or dangerous
driving practices. Reduce vehicle speed
and be especially careful when driving
and cornering on slippery surfaces. Al-
ways drive carefully.
● Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
approved for your vehicle or are ex-
tremely deteriorated, the ABLS system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the slip indicator light
may illuminate.
● If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extremely
deteriorated, the ABLS system may not
operate properly and the slip indicator
light may illuminate.

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
indicator flashes if this occurs. All other VDC
functions are off and the
indicator 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.
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 the
driver maintain stability but does not
prevent accidents due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Reduce vehicle speed and be especially
careful when driving and cornering on
slippery surfaces and always drive
carefully. ●
Do not modify the vehicle’s suspension.
If suspension parts such as shock ab-
sorbers, struts, springs, stabilizer bars,
bushings and wheels are not NISSAN
recommended for your vehicle or are
extremely deteriorated, the VDC system
may not operate properly. This could
adversely affect vehicle handling per-
formance, and the
indicator may
flash or the
indicator 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
indica-
tor light may illuminate.
● If engine control related parts are not
NISSAN recommended or are extremely
deteriorated, the
indicator light
may illuminate.
● When driving on extremely inclined sur-
faces such as higher banked corners,
the VDC system may not operate prop-
erly and the
indicator may flash or
the
indicator light may illuminate.
Do not drive on these types of roads. ●
When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the
indicator may flash or
the
indicator 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
indicator may flash or
the
indicator light may illuminate.
● The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road.

If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.
The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.Proper brake inspection intervals should
be followed.
For additional information regard-
ing brake inspections, refer to the appropriate
maintenance schedule information in the
“NISSAN Service and Maintenance Guide”.
Two types of fuses are used. Type
Ais used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type
Afuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type
Afuses can be installed in the engine
compartment and passenger compartment fuse
boxes.
