brake sensor NISSAN X-TRAIL 2006 Owners Manual

This procedure is described in the vehicle ser-
vice manual and can be performed by a NISSAN
dealer.
Using the brakes
Avoid resting your foot on the brake pedal while
driving. This will cause overheating of the brakes,
increases wear on the brakes and pads, and
reduces 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 acci-
dent.

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.
ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakes
so the wheels will not lock when braking abruptly
or when braking on slippery surfaces. The sys-
tem detects the rotation speed at each wheel
and varies the brake fluid pressure to prevent
each wheel from locking and sliding. By prevent-
ing wheel lockup, the system helps the driver
maintain steering control and helps to minimize
swerving and spinning on slippery surfaces.Using the systemDepress the brake pedal and hold it down.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.Normal operationThe anti-lock brake system will not operate at
speeds below 5 to 10 km/h (3 to 6 MPH) to
completely stop the vehicle. (The speeds willvary according to road conditions.) When the
anti-lock system senses that one or more wheels
are close to locking up, the actuator (under the
hood) rapidly applies and releases hydraulic
pressure (like pumping the brakes very quickly).
While the actuator is working, you may feel a
pulsation in the brake pedal and hear a noise or
vibration from the actuator under the hood. This
is normal and indicates that the anti-lock system
is working properly. However, the ABS operation
may indicate that road conditions are hazardous
and extra care is required while driving.
Self-test featureThe anti-lock brake system consists of electronic
sensors, electric pumps, and hydraulic solenoids
controlled by 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 is not an indication of any
malfunction. If the computer senses any mal-
function, it switches the anti-lock brake system
OFF and turns on the ABS warning light in the
meter. The brake system will then behave nor-
mally, but without anti-lock assistance.
If the light comes on during the self check, or
while you are driving, you should take your

vehicle to a NISSAN dealer for repair at your
earliest convenience.
WARNING
The anti-lock brake system is a sophis-
ticated device, but it cannot prevent ac-
cidents resulting from careless or dan-
gerous driving techniques. It can help
maintain vehicle control during braking
on slippery surfaces, but remember that
the stopping distance on slippery sur-
faces will be longer than on normal
surfaces, even with the anti-lock sys-
tem. 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 responsibility for safety of self and
others rests in the hands of the driver.
Tire type and condition of tires may also
affect braking effectiveness.

When replacing tires, install the
specified size of tires on all fourwheels.

When installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
“Vehicle identification” in the “9.
Technical and consumer informa-
tion” section for tire placard location.When accelerating or driving on a slippery sur-
faces, the tires may spin or slide. With the
Vehicle Dynamic Control (VDC) system, sensors
detect these movements and control the braking
and engine output to help improve vehicle sta-
bility.

When the VDC system is operating, the
“SLIP” indicator in the instrument panel
blinks.

When only the Traction Control System
(TCS) portion of the VDC system is operat-
ing, the “SLIP” indicator in the instrument
panel blinks.

If the “SLIP” indicator blinks, the road condi-
tions are slippery. Be sure to adjust your
speed and driving to these conditions. Be
sure to drive carefully. See “Slip indicator
light”, and “Vehicle Dynamic Control (VDC)
OFF indicator light” in the “2. Instruments and
controls” section.

Indicator light
If a malfunction occurs in the system, the
“SLIP” and “VDC OFF” indicator lights illumi-
nate in the instrument panel. As long as these
indicators are illuminated, the VDC system
function is canceled.
The VDC system uses an Active Brake Limited
Slip (ABLS) system to improve vehicle traction.
