brake sensor NISSAN 350Z 2003 Z33 Owners Manual

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 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
dashboard. The brake system will then behave
normally, 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 yourself
and others rests in the hands of the
driver.
Tire type and condition of tires may also
affect braking effectiveness.
IWhen replacing tires, install the
specified size for the front and rear
tires.IWhen installing a spare tire, make
sure it is the proper size and type as
specified on the tire placard. See
ªVehicle identificationº in the ª9.
Technical and consumer informationº

On slippery surfaces such as wet asphalt roads,
vehicle wheels may spin when the vehicle is
accelerated. This wheel spin reduces accelera-
tion, or causes the vehicle to swerve, thus
decreasing vehicle stability.
When the vehicle drive wheels begin to spin, the
traction control system (TCS) controls the en-
gine torque using an electronic control system,
and it also controls automatic control shifting if
necessary (for automatic transmission models).
This reduces spinning of the drive wheels, and
result in improved vehicle acceleration perfor-
mance. It also improves the vehicle stability by
swerving motion.
IIndicator light
If a malfunction occurs in the traction control
system, the SLIP and
indicator lights
come on in the meter panel.
As long as these indicator lights are on, the
traction control function is canceled. The
vehicle will behaves like a model without the
traction control system.
To cancel the traction control system manu-
ally, turn off the traction control system off
switch. (The
indicator light illuminates.)
WARNING
The traction control system is designed
to prevent the wheels from spinning.
However, it does not prevent vehicle
slipping or spinning due to abrupt steer-
ing operation at high speeds or by care-
less or dangerous driving techniques.
Be especially careful when driving on
slippery surfaces and always drive
safely.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.
IWhen the vehicle dynamic control system is
operating, the slip indicator light in the meter
panel blinks.
IWhen only the traction control system (TCS)
portion of the vehicle dynamic control system
is operating, the slip indicator light will also
blink.
IIf the slip indicator light blinks, the vehicle is
under slippery conditions. Be sure to drive
carefully. See ªSlip indicator lightº and ªVe-
hicle dynamic control off indicator lightº in the
ª2. Instruments and controlsº section.

If a malfunction occurs in the system, the

The VDC system uses a Brake Limited Slip
Differential (LSD) system to improve vehicle
traction. The brake LSD system works when one

LOW TIRE PRESSURE WARNING
SYSTEM (if so equipped)The low tire pressure warning system which
displays pressure of all tires (except the spare
tire) on the trip computer by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with a flat tire or very
low tire pressure (lower than 28 psi), the low tire
pressure warning system will activate and warn
you of it by the low tire pressure warning light (in
the meter panel) or the PSI indicator (on the trip
computer). This system will activate only when
the vehicle is driven at speeds above 20 MPH
(32 km/h). For more details, refer to ªTrip com-
puterº and ªWarning/indicator lights and audible
remindersº in the ª2. Instruments and controlsº
section and ªLow tire pressure warning systemº
in the ª5. Starting and drivingº section.
WARNING
IIf the low tire pressure warning light
comes on and/or the PSI indicator
flashes 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.
IWhen a spare tire is mounted or a
wheel is replaced, tire pressure will
not be indicated and the low tire
pressure warning system will not
function. Contact your NISSAN
dealer as soon as possible for tire
replacement and/or system reset-
ting.
IDo 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 manual transmission into R
(Reverse) position (automatic transmission 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

TOWING SAFETY
Trailer hitchChoose a proper hitch for your vehicle and
trailer. Make sure the trailer hitch is securely
attached to the vehicle, to help avoid personal
injury or property damage due to sway caused
by crosswinds, rough road surfaces or passing
trucks.
CAUTION
IDo not use axle-mounted hitches.
IThe hitch should not be attached to
or affect the operation of the impact-
absorbing bumper.
IDo not modify the vehicle exhaust
system, brake system, etc. to install atrailer hitch.
ITo 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. After the hitch is
removed, seal the bolt holes to pre-
vent exhaust fumes, water or dust
from entering the passenger com-
partment.
IRegularly check that all hitch mount-
ing bolts are securely mounted.
Tire pressuresIWhen towing a trailer, inflate the vehicle tires
to the recommended cold tire pressure indi-
cated on the tire placard (located on the
inside of the console box lid).
ITrailer 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 becrossed 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 tipsIBe certain your vehicle maintains a level
position 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-Technical and consumer information
