2003 NISSAN 350Z Owners Manual

BRAKING PRECAUTIONSThe brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.Vacuum assisted brakeThe brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. However,
greater foot pressure on the brake pedal will be
required to stop the vehicle and the stopping
distance will be longer.Using the brakesAvoid resting your foot on the brake pedal while
driving. This overheats the brakes, increases
wear on the brake linings 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
IWhile 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.
IIf the engine is not running or is
turned off while driving, the power
assist for the brakes will not work.
Braking will be harder.Wet brakesWhen the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly pressing the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.ANTI-LOCK BRAKE SYSTEM (ABS)The anti-lock brake system controls the brakesat 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 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
section for tire placard location.

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.

surface. The brake LSD system brakes the spin-
ning wheel to distribute the driving power to the
other driving wheel.
If the vehicle is operated with the vehicle dy-
namic control system turned off, all VDC and
TCS functions will be turned off. The brake LSD
system and ABS will still operate with the VDC
system off. If the brake LSD system or the ABS
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 normal.
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.
WARNING
IThe vehicle dynamic control systemis designed to help improve driving
stability but does not prevent acci-
dents due to abrupt steering opera-
tion at high speeds or by careless or
dangerous driving techniques. Re-
duce vehicle speed and be especially
careful when driving and cornering
on slippery surfaces and always drive
carefully.
IIf suspension parts such as shock
absorbers, struts, springs and bush-
ings are not standard equipment or
are extremely deteriorated, the ve-
hicle dynamic control off indicator
light may come on.
IWhen driving on extremely inclined
surfaces such as higher banked cor-
ners, the vehicle dynamic control sys-
tem may not operate properly or the
vehicle dynamic control off indicator
light may come on. Do not drive on
these types of roads.
IIf the tires other than the recom-
mended ones are used, the vehicle
dynamic control system may not op-erate properly or the vehicle dynamic
control off indicator light may come
on.
IThe vehicle dynamic control system
is not a substitute for winter tires or
tire chains on a snow covered road.

FREEING A FROZEN DOOR LOCKTo prevent a door lock from freezing, apply
de-icer or glycerin to it through the key hole. If
the lock becomes frozen, heat the key before
inserting it into the key hole.ANTI-FREEZEIn the winter when it is anticipated that the
temperature will drop below 32ÉF (0ÉC), check
anti-freeze to assure proper winter protection.
For additional information, see ªEngine Cooling
Systemº in the ª8. Maintenance and do-it-
yourselfº section.BATTERYIf the battery is not fully charged during extremely
cold weather conditions, the battery fluid may
freeze and damage the battery. To maintain
maximum efficiency, the battery should be
checked regularly. For additional information,
see ªBatteryº in the ª8. Maintenance and do-it-
yourselfº section.DRAINING OF COOLANT WATERIf the vehicle is to be left outside without anti-
freeze, drain the cooling system by opening the
drain plug located under the radiator. Refill
before operating the vehicle. See ªEngine cool-
ing systemº in the ª8. Maintenance and do-it-
yourselfº section for changing engine coolant.
TIRE EQUIPMENT1. SUMMER tires are of a tread design to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your vehicle
on snowy or icy roads, NISSAN recommends
the use of MUD & SNOW or ALL SEASON
tires on all four wheels. Please consult your
NISSAN dealer for the tire type, size, speed
rating and availability information.
2. For additional traction on icy roads, studded
tires may be used. However, some provinces
and states prohibit their use. Check local,
state and provincial laws before installing
studded tires.
Skid and traction capabilities of studded
snow tires, on wet or dry surfaces, may be
poorer than that of non-studded snow
tires.
3. Tire chains may be used if desired. Make sure
they are of proper size for the tires on your
vehicle and are installed according to the
chain manufacturer's suggestions. Use of tire
chains may be prohibited according to loca-
tion. Check the local laws before installing
tire chains. When installing tire chains, make
sure they are of proper size for the tires on
your vehicle and are installed according tothe chain manufacturer's suggestions.Use
only SAE Class S chains.Class ªSº chains
are used on vehicles with restricted tire to
vehicle clearance. Vehicles that can use
Class ªSº chains are designed to meet the
SAE standard minimum clearances between
the tire and the closest vehicle suspension or
body component required to accommodate
the use of a winter traction device (tire chains
or cables). The minimum clearances are de-
termined using the factory equipped tire size.
Other types may damage your vehicle. Use
chain tensioners when recommended by the
tire chain manufacturer to ensure a tight fit.
Loose end links of the tire chain must be
secured or removed to prevent the possibility
of whipping action damage to the fenders or
underbody. If possible, avoid fully loading
your vehicle when using tire chains. In addi-
tion, drive at a reduced speed. Otherwise,
your vehicle may be damaged and/or vehicle
handling and performance may be adversely
affected.
Never install tire chains on a T-type spare tire.
Do not use tire chains on dry roads.
SPECIAL WINTER EQUIPMENTIt is recommended that the following items be
carried in the vehicle during winter:
Ia scraper and stiff-bristled brush to remove

ice and snow from the windows and wiper
blades.
Ia sturdy, flat board to be placed under the
jack to give it firm support.
Ia shovel to dig the vehicle out of snow-drifts.
Iextra window washer fluid to refill the reser-
voir tank.
DRIVING ON SNOW OR ICE
WARNING
IWet ice (32ÉF, 0ÉC and freezing rain),
very cold snow or ice can be slick and
very hard to drive on. The vehicle will
have a lot less traction or grip under
these conditions. Try to avoid driving
on wet ice until the road is salted or
sanded.
IWhatever the condition, drive with
caution. Accelerate and slow down
with care. If accelerating or down-
shifting too fast, the drive wheels will
lose even more traction.
IAllow more stopping distance underthese conditions. Braking should be
started sooner than on dry pavement.
IAllow greater following distances on
slippery roads.
IWatch for slippery spots (glare ice).
These may appear on an otherwise
clear road in shaded areas. If a patch
of ice is seen ahead, brake before
reaching it. Try not to brake while
actually on the ice, and avoid any
sudden steering maneuvers.
IDo not use cruise control on slippery
roads.
ISnow can trap dangerous exhaust
gases under your vehicle. Keep snow
clear of the exhaust pipe and from
around your vehicle.
ENGINE BLOCK HEATER (if so
equipped)An engine block heater to assist extreme cold
temperature starting is available through your
NISSAN dealer.
WARNING
Do not use your heater with an un-
grounded electrical system or two-
pronged (cheater) adapters. You can be
injured by an electrical shock if you use
an ungrounded connection.
