BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking ability at two wheels.
You may feel a small click and hear a sound
when the brake pedal is fully depressed slowly.
This is not a malfunction and indicates that the
brake assist mechanism is operating properly.
Hydraulically-assisted brakes
The hydraulically-assisted brake system is de-
signed to use a hydraulic pump driven electri-
cally, to assist braking. If the engine stops, you
can stop the vehicle by depressing the foot
brake pedal. However, greater foot pressure on
the foot brake pedal will be required to stop the
vehicle. The stopping distance will be longer.
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 brakes, drive the vehicle at a safe speed
while lightly tapping 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
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 you visit a
NISSAN dealer for this service.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the
brakes, wearing out the brake and pads faster
and reduce gas mileage.
To help save the brakes 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, accelerat-
ing or downshifting. 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.
BRAKE SYSTEM

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 device. 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 dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal surfaces 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 Information
label. See “Tire and loading
information label” (P.10-12) .
— For detailed information, see “Wheels and tires” (P.8-30) .
The Anti-lock Braking System (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
prevent 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
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 dis-
tances.
Self-test feature
The 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 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
Starting and driving5-137
BRAKE ASSIST

5-138Starting and driving
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates 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. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.
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 control 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 conditions) .
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 automatically 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 lightwill 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 illuminates (for 4WD
models) .
See “Vehicle Dynamic Control (VDC) warning
light” (P.2-17) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-20).
VEHICLE DYNAMIC CONTROL (VDC)
SYSTEM

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 driv-
ing and cornering on slippery sur-
faces and always drive carefully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN recom-
mended for your vehicle or are
extremely deteriorated, the VDC
system may not operate properly.
This could adversely affect vehicle
handling performance, and the VDC warning light
may illuminate.
. If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. 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 warning
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 warn- ing light
may illuminate.
. The VDC system is not a substitute
for winter tires or tire chains on a
snow covered road.

VEHICLE DYNAMIC CONTROL (VDC)
OFF SWITCH
The vehicle should be driven with the Vehicle
Dynamic Control (VDC) system ON for most
driving conditions.
When the vehicle is stuck in mud or snow, the
VDC system reduces the engine output to
reduce wheel spin. The engine speed will be
reduced even if the accelerator is depressed to
the floor. If maximum engine power is needed to
free a stuck vehicle, turn the VDC system off.
To turn off the Vehicle Dynamic Control (VDC)
system, push the VDC OFF switch. The VDC off
indicator light
will illuminate.Push the VDC OFF switch again or restart the
engine to turn ON the system.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock becomes
frozen, heat the key before inserting it into the
key hole or use the Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 328F(0
8C) ,
check antifreeze to assure proper winter protec-
tion. For additional information, see “Engine
cooling system” (P.8-4).
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery should
be checked regularly. For additional information,
see “Battery” (P.8-11) .
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see “Engine cooling system”
(P.8-4) .
COLD WEATHER DRIVING

TIRE EQUIPMENT
SUMMER tires have a tread designed to provide
superior performance on dry pavement. How-
ever, the performance of these tires will be
substantially reduced in snowy and icy condi-
tions. If you operate 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 you consult a NISSAN dealer
for the tire type, size, speed rating and
availability information.
For additional traction on icy roads, studded
tires may be used. However, some U.S. states
and Canadian provinces prohibit their use.
Check local, state and provincial laws before
installing 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.
Tire chains may be used. For details, see “Tire
chains” (P.8-36) .
For four-wheel drive
If you install snow tires, they must also be the
same size, brand, construction and tread pattern
on all four wheels.
SPECIAL WINTER EQUIPMENT
It is recommended that the following items be
carried in the vehicle during winter:
.A scraper and stiff-bristled brush to remove
ice and snow from the windows and wiper
blades.
. A sturdy, flat board to be placed under the
jack to give it firm support.
. A shovel to dig the vehicle out of snowdrifts.
. Extra window washer fluid to refill the
reservoir tank.
DRIVING ON SNOW OR ICE
WARNING
.Wet ice (328F, 0 8C and freezing rain) ,
very cold snow or ice can be slick
and very hard to drive on. The
vehicle will have much less traction
or “grip” under these conditions. Try
to avoid driving on wet ice until the
road is salted or sanded.
. Whatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels
will lose even more traction. .
Allow more stopping distance under
these conditions. Braking should be
started sooner than on dry pave-
ment.
. Allow greater following distances
on slippery roads.
. Watch for slippery spots (glare ice) .
These may appear on an otherwise
clear road in shaded areas. If a
patch of ice is seen ahead, brake
before reaching it. Try not to brake
while on the ice, and avoid any
sudden steering maneuvers.
. Do not use the cruise control on
slippery roads.
. Snow can trap dangerous exhaust
gases under your vehicle. Keep
snow clear of the exhaust pipe and
from around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)
Engine block heaters are used to assist in cold
temperature starting.
The engine block heater should be used when
the outside temperature is 208F( í78C) or lower.
Starting and driving5-141

5-142Starting and driving
To use the engine block heater
1. Turn the engine off.
2. Open the hood and unwrap the engineblock heater cord.
3. Plug the engine block heater cord into a grounded 3-wire, 3-pronged extension cord.
4. Plug the extension cord into a Ground Fault Interrupt (GFI) protected, grounded 110-
volt AC (VAC) outlet.
5. The engine block heater must be plugged in for at least 2 - 4 hours, depending on
outside temperatures, to properly warm the
engine coolant. Use an appropriate timer to
turn the engine block heater on.
6. Before starting the engine, unplug and properly store the cord to keep it away from
moving parts.
WARNING
.Do not use your engine block heater
with an ungrounded electrical sys-
tem or a 2-pronged adapter. You can
be seriously injured by an electrical
shock if you use an ungrounded
connection. .
Disconnect and properly store the
engine block heater cord before
starting the engine. Damage to the
cord could result in an electrical
shock and can cause serious injury.
. Use a heavy-duty 3-wire, 3-pronged
extension cord rated for at least
10A. Plug the extension cord into a
Ground Fault Interrupt (GFI) pro-
tected, grounded 110-VAC outlet.
Failure to use the proper extension
cord or a grounded outlet can result
in a fire or electrical shock and
cause serious personal injury.
