5-42Starting and driving

∙ Once the automatic brake controloperates, it does not operate again if
the vehicle approaches the same
obstacle.
∙ The automatic brake control can only operate for a short period of time.
Therefore, the driver must depress
the brake pedal.
∙ In the following situations, the RAB system may not operate properly or
may not function sufficiently:
– The vehicle is driven in bad weather (rain, fog, snow, etc.).
– The vehicle is driven on a steep hill.
– The vehicle’s posture is changed (e.g., when driving over a bump).
– The vehicle is driven on a slippery road.
– The vehicle is turned sharply by turning the steering wheel fully.
– Snow chains are used.
– Wheels or tires other than NISSAN recommended are used. – The brakes are cold at low ambient
temperatures or immediately af ter
driving has started.
– The braking force becomes poor due to wet brakes af ter driving
through a puddle or washing the
vehicle.
∙ Turn the RAB system off in the follow- ing conditions to prevent the occur-
rence of an unexpected accident
resulting from sudden system
operation:
– The vehicle is towed.
– The vehicle is carried on a flatbed truck.
– The vehicle is on the chassis dynamometer.
– The vehicle drives on an uneven road surface.
– Suspension parts other than those designated as Genuine NISSAN
parts are used. (If the vehicle
height or the vehicle body inclina-
tion is changed, the system may
not detect an obstacle correctly.) ∙ Excessive noise (e.g., audio system
volume, an open vehicle window) will
interfere with the chime sound, and it
may not be heard.
SYSTEM MALFUNCTION
If the RAB system malfunctions, it will be
turned off automatically, the RAB system
warning light will illuminate, and the “Sys-
tem fault” warning message will appear in
the vehicle information display.
Action to take
If the warning light illuminates, park the ve-
hicle in a safe location, turn the engine off,
and restart the engine. If the warning light
continues to illuminate, have the RAB sys-
tem checked. It is recommended that you
visit a NISSAN dealer for this service.
NOTE:
If the RAB system cannot be operated
temporarily, the RAB system warning
light blinks.

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 perfor-
mance.
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, butit 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 vehicle 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, refer to “Tire
and Loading Information label” in
the “Technical and consumer infor-
mation” section of this manual.
– For additional information, refer to “Wheels and tires” in the “Do-it-
yourself ” section of this manual.
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) 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 for-
ward 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 sys-
tem then operates normally but without
anti-lock assistance.

illuminate. This is not a malfunction.
Restart the engine af ter driving onto
a stable surface. ∙ If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not oper-
ate properly and the
indicator
light 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.
BRAKE FORCE DISTRIBUTION
During braking while driving through turns,
the system optimizes the distribution of
force to each of the front and rear wheels
depending on the radius of the turn.
WARNING
∙ The VDC system is designed to helpthe driver maintain 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 surfaces and
always drive carefully. ∙ Do not modif y the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs, sta-
bilizer 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 performance, and
the
indicator light 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 ex-
tremely deteriorated, the VDC system
may not operate properly and both

∙ The VDC system is not a substitute for winter tires or tire chains on a snow
covered road. The chassis control is an electric control
module that includes the following func-
tions:
∙ Intelligent Trace Control
∙ 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, refer to “Vehicle information dis-
play” in the “Instruments and controls” sec-
tion of this manual.
When the VDC system is turned off, the I-TC
is also turned off.
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 turned off, some functions
will remain on to assist the driver (for ex-
ample, avoidance scenes).
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 system is turned off, the ARC
is also turned off.
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.
