ESP NISSAN 370Z ROADSTER 2014 Z34 Owner's Manual

5-26Starting and driving
4. Push the ignition switch to the OFF position.
WARNING
If the engine is not running or is turned
off while driving, the power assist for
the steering will not work. Steering will
be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The 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.
Wet brakes
When 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 tapping 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.
POWER STEERING BRAKE SYSTEM

PARKING BRAKE BREAK-IN
Break in the parking brake shoes whenever the
stopping effect of the parking brake is weakened
or whenever the parking brake shoes and/or
drums/rotors are replaced, in order to assure the
best braking performance.
This procedure is described in the vehicle
service 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, wearing out the brake and pads faster
and reduce 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 accident.
. 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.
BRAKE ASSIST
When the force applied to the brake pedal
exceeds a certain level, the Brake Assist is
activated generating greater braking force than a
conventional brake booster even with light pedal
force.
WARNING
The Brake Assist is only an aid to assist
braking operation and is not a collision
warning or avoidance device. It is the
driver’s responsibility to stay alert, drive
safely and be in control of the vehicle at
all times.
ANTI-LOCK BRAKING SYSTEM (ABS)
WARNING
.The Anti-lock Braking System (ABS)
is a sophisticated device, but it
cannot prevent accidents resulting
from careless or dangerous driving
techniques. It can help maintain
vehicle control during braking on
slippery surfaces. Remember that
stopping distances on slippery sur-
faces will be longer than on normal
Starting and driving5-27
BRAKE ASSIST

5-28Starting and driving
surfaces even with ABS. 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 driver is responsible
for safety.
. Tire type and condition 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 that it is the proper
size and type as specified on the
Tire and Loading Information
label. See “Tire and Loading
Information label” (P.9-13) of
this manual.
— For detailed information, see “Wheels and tires” (P.8-30) of
this manual.
The Anti-lock Braking System (ABS) controls
the brakes so the wheels do not lock during hard
braking 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 each wheel from locking, the system
helps the driver maintain steering control and
helps to minimize swerving and spinning on
slippery surfaces.
Using the system
Depress the brake pedal and hold it down.
Depress the brake pedal with firm steady
pressure, but do not pump the brakes. The
ABS will operate to prevent the wheels from
locking up. Steer the vehicle to avoid obstacles.
WARNING
Do not pump the brake pedal. Doing so
may result in increased stopping dis-
tances.
Self-test feature
The ABS includes electronic sensors, electric
pumps, hydraulic solenoids and 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 does notindicate a malfunction. If the computer senses
a malfunction, it switches the ABS off and
illuminates the ABS warning light on the
instrument panel. The brake system then oper-
ates normally, but without anti-lock assistance.
If the ABS warning light illuminates during the
self-test or while driving, have the vehicle
checked by a NISSAN dealer.
Normal operation
The ABS operates at speeds above 3 to 6 MPH
(5 to 10 km/h).
When the ABS senses that one or more wheels
are close to locking up, the actuator rapidly
applies and releases hydraulic pressure. This
action is similar to pumping the brakes very
quickly. You may feel a pulsation in the brake
pedal and hear a noise from under the hood or
feel a vibration from the actuator when it is
operating. This is normal and indicates that the
ABS is operating properly. However, the pulsa-
tion may indicate that road conditions are
hazardous and extra care is required while
driving.

The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver inputs
and vehicle motion. Under certain driving con-
ditions, the VDC system helps to perform the
following functions.
.Controls brake pressure to reduce wheel
slip on one slipping drive wheel so power is
transferred to a non slipping drive wheel on
the same axle.
. Controls brake pressure and engine output
to reduce drive wheel slip based on vehicle
speed (traction control function) .
. Controls brake pressure at individual wheels
and engine output to help the driver maintain
control of the vehicle in the following
conditions:
— understeer (vehicle tends to not follow
the steered path despite increased
steering input)
— oversteer (vehicle tends to spin due to certain road or driving conditions) .
The VDC system can help the driver to maintain
control of the vehicle, but it cannot prevent loss
of vehicle control in all driving situations.
When the VDC system operates, the VDC
warning light
in the instrument panel flashes
so note the following:
. The road may be slippery or the system may
determine some action is required to help keep the vehicle on the steered path.
. 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 properly.
. Adjust your speed and driving to the road
conditions.
See “Vehicle Dynamic Control (VDC) warning
light” (P.2-15).
If a malfunction occurs in the system, the VDC
warning light
illuminates in the instrument
panel. The VDC system automatically turns off.
The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator
illuminates to
indicate the VDC system is off. When the VDC
switch is used to turn off the system, the VDC
system still operates to prevent one drive wheel
from slipping by transferring power to a non
slipping drive wheel. The VDC warning light
flashes if this occurs. All other VDC functions
are off, and the VDC warning lightwill not
flash. The VDC system is automatically reset to
on when the ignition switch is placed in the off
position then back to the on position.
See “Vehicle Dynamic Control (VDC) warning
light” (P.2-15) and “Vehicle Dynamic Control
(VDC) off indicator light” (P.2-17).
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
.
The VDC system is designed to help
the driver maintain stability but
does not prevent accidents due to
abrupt steering operation at high
speeds or by careless or dangerous
driving techniques. Reduce vehicle
speed and be especially careful
when driving and cornering on slip-
pery surfaces and always drive care-
fully.
. Do not modify the vehicle’s suspen-
sion. If suspension parts such as
shock absorbers, struts, springs,
stabilizer bars, bushings and
wheels are not NISSAN recom-
mended for your vehicle or are
extremely deteriorated, the VDC
system may not operate properly.
This could adversely affect vehicle
handling performance, and the VDC
warning light
may illuminate.

7-2Appearance and care
In order to maintain the appearance of your
vehicle, it is important to take proper care of it.
To protect the paint surface, wash your vehicle
as soon as you can:
.after a rainfall to prevent possible damage
from acid rain
. after driving on coastal roads
. when contaminants such as soot, bird
droppings, tree sap, metal particles or bugs
get on the paint surface
. when dust or mud builds up on the surface
Whenever possible, store or park your vehicle
inside a garage or in a covered area.
When it is necessary to park outside, park in a
shady area or protect the vehicle with a body
cover.
Be careful not to scratch the paint surface
when putting on or removing the body
cover.WASHING
Wash dirt off the vehicle with a wet sponge and
plenty of water. Clean the vehicle thoroughly
using a mild soap, a special vehicle soap or
general purpose dishwashing liquid mixed with
clean, lukewarm (never hot) water.
CAUTION
. Do not use car washes that use acid
in the detergent. Some car washes,
especially brushless ones, use some
acid for cleaning. The acid may react
with some plastic vehicle compo-
nents, causing them to crack. This
could affect their appearance, and
also could cause them not to func-
tion properly. Always check with
your car wash to confirm that acid
is not used.
. Do not wash the vehicle with strong
household soap, strong chemical
detergents, gasoline or solvents.
. Do not wash the vehicle in direct
sunlight or while the vehicle body is
hot, as the surface may become
water-spotted. .
Avoid using tight-napped or rough
cloths, such as washing mitts. Care
must be taken when removing
caked-on dirt or other foreign sub-
stances so the paint surface is not
scratched or damaged.
. For Roadster models, observe the
following:
— Do not use an automatic car
wash or a high pressure car
wash. The soft top may be
damaged.
— Avoid applying direct water pressure, such as high pres-
sured water from household
hoses, on the lining of the soft
top and vehicle body. Avoid
applying continuous water on
the parts around the soft top
and the windows. These may
cause water to leak into the
inside of your vehicle.
Rinse the vehicle thoroughly with plenty of clean
water.
Inside flanges, seams and folds on the doors,
hatches and hood are particularly vulnerable to
the effects of road salt. Therefore, these areas
CLEANING EXTERIOR

must be regularly cleaned. Make sure that the
drain holes in the lower edge of the door are
open. Spray water under the body and in the
wheel wells to loosen the dirt and wash away
road salt.
Avoid leaving water spots on the paint surface
by using a damp chamois to dry the vehicle.
SAI0046
NISMO models
CAUTION
Do not use an automatic car wash for
NISMO models. The rear spoiler may be
damaged.
SOFT TOP CARE AND CLEANING
(Roadster models)
Proper care and handling should be observed to
maintain a good appearance of the soft top.
Improper care may cause the top cloth’s surface
to stiffen, stain, or mat. Follow the instructions
shown in this section.
It is not necessary to wash the soft top every
time you wash the vehicle body, but clean the
top regularly before it becomes quite dirty.
Leaving the soft top dirty or soiled for a long
period will cause deterioration to the quality of
the top material.
Remove dust or dirt on the soft top with a soft
brush or sponge, then rinse it with plenty of
clean water. When the top is quite dirty, wash
using a mild detergent, such as a general
cleaner especially made for a cloth top or a
general purpose dish-washing liquid, mixed with
clean, lukewarm (never hot) water. Rinse the top
again with plenty of clean water to remove all
traces of soap.
CAUTION
.Do not use strong household soap,
strong chemical detergents, gaso-
line or solvents.
Appearance and care7-3

CAUTION
Do not use abrasive cleaners when
washing the wheels.
Aluminum alloy wheels
Wash regularly with a sponge dampened in a
mild soap solution, especially during winter
months in areas where road salt is used. Salt
could discolor the wheels if not removed.
CAUTION
Follow the directions below to avoid
staining or discoloring the wheels:
.Do not use a cleaner that uses
strong acid or alkali contents to
clean the wheels.
. Do not apply wheel cleaners to the
wheels when they are hot. The
wheel temperature should be the
same as ambient temperature.
. Rinse the wheel to completely re-
move the cleaner within 15 minutes
after the cleaner is applied.
CHROME PARTS
Clean chrome parts regularly with a non-
abrasive chrome polish to maintain the finish.
TIRE DRESSING
NISSAN does not recommend the use of tire
dressings. Tire manufacturers apply a coating to
the tires to help reduce discoloration of the
rubber. If a tire dressing is applied to the tires, it
may react with the coating and form a com-
pound. This compound may come off the tire
while driving and stain the vehicle paint.
If you choose to use a tire dressing, take the
following precautions:
.Use a water-based tire dressing. The coat-
ing on the tire dissolves more easily with an
oil-based tire dressing.
. Apply a light coat of tire dressing to help
prevent it from entering the tire tread/
grooves (where it would be difficult to
remove) .
. Wipe off excess tire dressing using a dry
towel. Make sure the tire dressing is
completely removed from the tire tread/
grooves.
. Allow the tire dressing to dry as recom-
mended by tire dressing manufacturer. Occasionally remove loose dust from the interior
trim, plastic parts and seats using a vacuum
cleaner or soft bristled brush. Wipe the vinyl and
leather surfaces with a clean, soft cloth dam-
pened in mild soap solution, then wipe clean
with a dry soft cloth.
Regular care and cleaning is required in order to
maintain the appearance of the leather.
Before using any fabric protector, read the
manufacturer’s recommendations. Some fabric
protectors contain chemicals that may stain or
bleach the seat material.
Use a cloth dampened only with water, to clean
the meter and gauge lens.
WARNING
Do not use water or acidic cleaners (hot
steam cleaners) on the seat. This can
damage the seat or occupant classifica-
tion sensor. This can also affect the
operation of the air bag system and
result in serious personal injury.

MOST COMMON FACTORS CONTRI-
BUTING TO VEHICLE CORROSION
.The accumulation of moisture-retaining dirt
and debris in body panel sections, cavities,
and other areas.
. Damage to paint and other protective coat-
ings caused by gravel and stone chips or
minor traffic accidents.
ENVIRONMENTAL FACTORS INFLU-
ENCE THE RATE OF CORROSION
Moisture
Accumulation of sand, dirt and water on the
vehicle body underside can accelerate corro-
sion. Wet floor coverings will not dry completely
inside the vehicle, and should be removed for
drying to avoid floor panel corrosion.
Relative humidity
Corrosion will be accelerated in areas of high
relative humidity, especially those areas where
the temperatures stay above freezing where
atmospheric pollution exists, or where road salt
is used.
Temperature
A temperature increase will accelerate the rate
of corrosion to those parts which are not well
ventilated.
Air pollution
Industrial pollution, the presence of salt in the air
in coastal areas, or heavy road salt use will
accelerate the corrosion process. Road salt will
also accelerate the disintegration of paint
surfaces.
TO PROTECT YOUR VEHICLE FROM
CORROSION
.Wash and wax your vehicle often to keep the
vehicle clean.
. Always check for minor damage to the paint
and repair it as soon as possible.
. Keep drain holes at the bottom of the doors
open to avoid water accumulation.
. Check the underbody for accumulation of
sand, dirt or salt. If present, wash with water
as soon as possible.
CAUTION
.NEVER remove dirt, sand or other
debris from the passenger compart-
ment by washing it out with a hose. Remove dirt with a vacuum cleaner.
. Never allow water or other liquids to
come in contact with electronic
components inside the vehicle as
this may damage them.
Chemicals used for road surface deicing are
extremely corrosive. They accelerate corrosion
and deterioration of underbody components
such as the exhaust system, fuel and brake
lines, brake cables, floor pan and fenders.
In winter, the underbody must be cleaned
periodically.
For additional protection against rust and
corrosion, which may be required in some areas,
consult a NISSAN dealer.
CORROSION PROTECTION

Some day-to-day and regular maintenance is
essential to maintain your vehicle’s good me-
chanical condition, as well as its emission and
engine performance.
It is the owner’s responsibility to make sure that
the scheduled maintenance, as well as general
maintenance, is performed.
As the vehicle owner, you are the only one who
can ensure that your vehicle receives the proper
maintenance care. You are a vital link in the
maintenance chain.
SCHEDULED MAINTENANCE
For your convenience, both required and op-
tional scheduled maintenance items are de-
scribed and listed in your “NISSAN Service and
Maintenance Guide”. You must refer to that
guide to ensure that necessary maintenance is
performed on your vehicle at regular intervals.
GENERAL MAINTENANCE
General maintenance includes those items
which should be checked during normal day-
to-day operation. They are essential for proper
vehicle operation. It is your responsibility to
perform these procedures regularly as pre-
scribed.
Performing general maintenance checks re-
quires minimal mechanical skill and only a few
general automotive tools.These checks or inspections can be done by
yourself, a qualified technician or, if you prefer, a
NISSAN dealer.
WHERE TO GO FOR SERVICE
If maintenance service is required or your vehicle
appears to malfunction, have the systems
checked and serviced by a NISSAN dealer.
NISSAN technicians are well-trained specialists
and are kept up to date with the latest service
information through technical bulletins, service
tips, and in-dealership information systems.
They are completely qualified to work on
NISSAN vehicles
beforework begins.
You can be confident that a NISSAN dealer’s
service department performs the best job to
meet the maintenance requirements on your
vehicle. During the normal day-to-day operation of the
vehicle, general maintenance should be per-
formed regularly as prescribed in this section. If
you detect any unusual sounds, vibrations or
smell, be sure to check for the cause or have a
NISSAN dealer do it promptly. In addition, you
should notify a NISSAN dealer if you think that
repairs are required.
When performing any checks or maintenance
work, see “Maintenance precautions” (P.8-6) .
EXPLANATION OF MAINTENANCE
ITEMS
Additional information on the following
items with “*” is found later in this section.
Outside the vehicle
The maintenance items listed here should be
performed from time to time, unless otherwise
specified.
Doors and engine hood:
Check that all doors
and the engine hood, operate properly. Also
ensure that all latches lock securely. Lubricate
hinges, latches, latch pins, rollers and links if
necessary. Make sure that the secondary latch
keeps the hood from opening when the primary
latch is released.
When driving in areas using road salt or other
corrosive materials, check lubrication frequently.
Lights*: Clean the headlights on a regular basis.
