brake sensor NISSAN MURANO 2004 1.G Owners Manual

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
at each wheel so the wheels will not lock when
braking abruptly 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 wheel lockup, the system helps
the driver maintain steering control and helps to
minimize swerving and spinning on slippery sur-
faces.
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 3 to 6 MPH (5 to 10 km/h) to
completely stop the vehicle. (The speeds will
vary 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 operationmay 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 your 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 four
wheels.

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 driving on slippery surfaces or suddenly
avoiding obstacles on roads, the vehicle might
swerve or slip. With the vehicle dynamic control
(VDC) system, sensors detect these movements
and control the braking and engine output to
help improve vehicle stability while driving. The
system also varies the brake fluid pressure to
prevent each wheel from locking.

When the VDC system is operating, the slip
indicator in the instrument panel blinks.

When only the traction control system portion
of the VDC system is operating, the slip
indicator will also blink.

If the slip indicator blinks, the vehicle is under
slippery conditions. Be sure to drive carefully.
See “Slip indicator light”, and “VDC off indi-
cator light” in the “2. Instruments and con-
trols” section.

Indicator light
If a malfunction occurs in the system, the
SLIP and
indicator lights come on in
the meter panel.
As long as these warning lights are on, the
traction control function is canceled.
The VDC uses an Active Brake Limited Slip
(ABLS) system to improve vehicle traction. The
Active Brake Limited Slip system works when
one of the driving wheels in spinning on a
slippery surface. The ABLS system brakes thespinning wheel which distributed the driving
power to the other drive wheel. If the vehicle is
operated with the vehicle dynamic control sys-
tem turned off, all VDC and traction control
functions will be turned off. The ABLS and ABS
system will still operate with the VDC system off.
If the ABLS system or the ABS system is
activated, the slip indicator light will blink and
you may hear a clunk noise and/or feel a pulsa-
tion in the brake pedal. This is also normal and
indicates the brake fluid pressure is controlled
properly.
While the VDC system is operating, 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 prop-
erly.
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.

LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)This vehicle is equipped with the low tire pres-
sure warning system, which displays the pres-
sure of each tire independently (except the spare
tire) on the display screen by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with low tire pressure
(lower than 27 psi, 190 kPa), the low tire
pressure warning system will activate and warn
you of it by the low tire pressure warning light.
This system will activate only when the vehicle is
driven at speeds above 20 MPH (32 km/h). For
more details, please refer to “Warning/indicator
lights and audible reminders” in the “2. Instru-
ments and controls” section, “Tire pressure in-
formation” in the “4. Display screen, heater, air
conditioner and audio systems” section and
“Low tire pressure warning system” in the “5.
Starting and driving” section.
WARNING

If the light comes on while driving,
avoid sudden steering maneuvers or
abrupt braking, reduce vehicle speed,
pull off the road to a safe location
and stop the vehicle as soon as pos-sible. Serious vehicle damage could
occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to
the recommended COLD tire pres-
sure shown on the Tire and Loading
Information label to turn the low tire
pressure warning light OFF. If the
light still comes on while driving after
adjusting the tire pressure, a tire may
be flat. If you have a flat tire, replace
it with a spare tire as soon as pos-
sible.

When a spare tire is mounted or a
wheel is replaced, the pressure of
that tire will not be indicated or moni-
tored by the low tire pressure warn-
ing system. Contact your NISSAN
dealer as soon as possible for tire
replacement and/or system reset-
ting.

Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pres-sure sensors.
CHANGING A FLAT TIREIf you have a flat tire, follow the instructions
below.Stopping the vehicle1. Safely move the vehicle off the road away
from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking
brake. Shift the selector lever into P (Park)
position.
4. Turn off the engine.
5. Raise the hood to warn other traffic, and to
signal professional road assistance person-
nel that you need assistance.
6. Have all passengers get out of the vehicle
and stand in a safe place, away from traffic
and clear of the vehicle.
