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.
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.
POWER STEERING BRAKE SYSTEM

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 light
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
light
will 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.
. If brake related parts such as brake
pads, rotors and calipers are not
NISSAN recommended or are extre-
mely deteriorated, the VDC system
may not operate properly and the
VDC warning light
may illumi-
nate.
. If engine control related parts are
not NISSAN recommended or are
extremely deteriorated, the VDC
warning light
may illuminate.
. When driving on extremely inclined
surfaces such as higher banked
corners, the VDC system may not
operate properly and the VDC warn-
ing light
may illuminate. Do not
drive on these types of roads.
. When driving on an unstable sur-
face such as a turntable, ferry,
elevator or ramp, the VDC warning
light
may illuminate. This is not
a malfunction. Restart the engine
after driving onto a stable surface.
. If wheels or tires other than the
NISSAN recommended ones are
used, the VDC system may not

Installing the spare tire
The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading “Wheels and tires” (P.8-
30) .)
1. Clean any mud or dirt from the surfacebetween the wheel and hub.
2. Carefully put the spare tire on and tighten the wheel nuts finger tight. Check that all the
wheel nuts contact the wheel surface
horizontally.
Models equipped with different sized
tires in the front and rear:
When replacing a front tire, make sure that the hole in the spare tire wheel is aligned
with the pin on the brake rotor.
3. With the wheel nut wrench, tighten wheel nuts alternately and evenly in the sequence
as illustrated (
*1,*2,*3,*4,*5) until
they are tight.
4. Lower the vehicle slowly until the tire touches the ground. Then, with the wheel
nut wrench, tighten the wheel nuts securely
in the sequence as illustrated. Lower the
vehicle completely.
WARNING
.Incorrect wheel nuts or improperly
tightened wheel nuts can cause the
wheel to become loose or come off.
This could cause an accident.
. Do not use oil or grease on the
wheel studs or nuts. This could
cause the nuts to become loose.
. Retighten the wheel nuts when the
vehicle has been driven for 600
miles (1,000 km) (also in cases of a
flat tire, etc.) .
. As soon as possible, tighten the wheel
nuts to the specified torque with a torque wrench.
Wheel nut tightening torque:
80 ft-lb (108 N·m)
The wheel nuts must be kept tightened
to specification at all times. It is
recommended that wheel nuts be tigh-
tened to specifications at each lubrica-
tion interval.
. Adjust tire pressure to the COLD pres-
sure.
COLD pressure:
After the vehicle has been parked for
three hours or more or driven less than
1 mile (1.6 km) .
COLD tire pressures are shown on the
Tire and Loading Information label
affixed to the driver side center pillar.
Stowing the damaged tire and tools
Coupe models:
1. Securely store the damaged tire and jacking
tools in the storage area.
2. Place the spare tire cover and the cargo room carpet over the damaged tire.
3. Close the rear hatch.
In case of emergency6-7

tire chains in such conditions can cause damage
to the various mechanisms of the vehicle due to
some overstress.
CHANGING WHEELS AND TIRES
Tire rotation
Tires cannot be rotated on this vehicle
because the front tires are a different size
than the rear tires.
A pin is on the front brake rotor to prevent
the rear wheels from being installed in
place of the front wheels. The spare tire
can be installed in place of the front and
rear wheels. When installing the spare tire
in the front wheel, the hole in the spare tire
wheel must be aligned with the pin on the
brake rotor.
WARNING
.Retighten the wheel nuts when
the vehicle has been driven for
600 miles (1,000 km) (also in
cases of a flat tire, etc.) .
. For additional information re-
garding tires, refer to “Important
Tire Safety Information” (US) or “Tire Safety Information” (Cana-
da) in the Warranty Information
Booklet.
