2003 NISSAN MURANO brake sensor

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 pulsation mayindicate 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 a brake Limited Slip Differential
(LSD) system to improve vehicle traction. The
brake LSD system works when one of the driving
wheels in spinning on a slippery surface. Thebrake LSD system brakes the spinning wheel
which distributed the driving power to the other
drive wheel. If the vehicle is operated with the
vehicle dynamic control system turned off, all
VDC and traction control functions will be turned
off. The brake LSD and ABS system will still
operate with the VDC system off. If the brake
LSD system or the ABS system is activated, the
slip indicator light will blink and you may hear a
clunk noise and/or feel a pulsation 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 low tire pressure warning light
blinks while driving, avoid sudden
steering maneuvers or abrupt brak-
ing, reduce vehicle speed, pull off the
road to a safe location and stop thevehicle as soon as possible. Serious
vehicle damage could occur and may
lead to an accident and could result
in serious personal injury. Check the
pressure for all four tires and adjust
the pressure to the COLD tire pres-
sure shown on the tire placard. If you
have a flat tire, replace it with a spare
tire as soon as possible.

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 in 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.
WARNING

Make sure that the parking brake is
securely applied and the selector le-
ver is shifted into P (Park).

Never change tires when the vehicle
is on a slope, ice or slippery areas.
This is hazardous.

Never change tires if oncoming traffic

After the hitch is removed, seal the
bolt holes to prevent exhaust fumes,
water or dust from entering the pas-
senger compartment.

Regularly check all hitch mounting
bolts are securely mounted.

To reduce the possibility of addi-
tional damage if your vehicle is
struck from the rear, where practical,
remove the hitch and/or receiver
when not in use.

Never connect a trailer brake system
directly to the vehicle brake system.Tire pressures
When towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard (located on the
driver’s door center pillar).

Trailer tire condition, size, load rating and
proper inflation pressure should be in accor-
dance with the trailer and tire manufacturers’
specifications.
Safety chainAlways use a suitable chain between your ve-
hicle and the trailer. The chain should be
crossed and should be attached to the hitch, not
to the vehicle bumper or axle. Be sure to leave
enough slack in the chain to permit turning
corners.Trailer lightsTrailer lights should comply with federal and/or
local regulations. When wiring the vehicle for
towing, connect the stop and tail light pickup
into the vehicle electrical circuit at a point be-
tween the sensor and stop light or light switch.Trailer brakesIf your trailer is equipped with a braking system,
make sure it conforms to federal and/or local
regulations and that it is properly installed.
WARNING
Never connect a trailer brake system
directly to the vehicle brake system.Pre-towing tips
Be certain your vehicle maintains a levelposition when a loaded and/or unloaded
trailer is hitched. Do not drive the vehicle if it
has an abnormal nose-up or nose-down con-
dition; check for improper tongue load, over-
load, worn suspension or other possible
causes of either condition.

Always secure items in the trailer to prevent
load shifts while driving.

Be certain your rear view mirrors conform to
all federal, state or local regulations. If not,
install any mirrors required for towing before
driving the vehicle.
Trailer towing tipsIn order to gain skill and an understanding of the
vehicle’s behavior, you should practice turning,
stopping and backing up in an area which is free
from traffic. Steering stability, and braking per-
formance will be somewhat different than under
normal driving conditions.

Always secure items in the trailer to prevent
load shift while driving.

Avoid abrupt starts, acceleration or stops.

Avoid sharp turns or lane changes.

Always drive your vehicle at a moderate
speed.

Always block the wheels on both vehicle andTechnical and consumer information
