BRAKING PRECAUTIONS GUID-69469B45-E0A5-4BC3-B99F-C3213CC27874
The brake system has two separate hy-
draulic circuits. If one circuit malfunctions,
you will still have braking at two wheels.
Vacuum assisted brakes GUID-95686AE6-7A34-4D3E-9305-085085C76F84
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 pres-
sure on the brake pedal will be required to
stop the vehicle and the stopping distance
will be longer.
When the brake pedal is depressed slowly
and firmly, you may hear a clicking noise
and feel a slight pulsation. This is normal
and indicates that the Brake Assist System
is operating.
Wet brakes GUID-B2433212-C5E2-4B61-9394-8ED34BB6A681
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 GUID-B441C7AD-F0BB-453E-A531-8E92178C3484
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
an INFINITI retailer.
Using the brakes GUID-EB3F3C9C-0F2F-47F8-8239-331D9D489654
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, accelerating or
downshifting. Abrupt braking or accel-
erating 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.

5-51BRAKE SYSTEM

Black plate (376,1)
[ Edit: 2012/ 1/ 17 Model: V36-D ]5-56 Starting and drivingflashes 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) warn-
ing light ” (P.2-17).
If a malfunction occurs in the system, the
VDC warning light
illuminates in the
instrument panel. The VDC system auto-
matically 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 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) warn-
ing light ” (P.2-17) and “ Vehicle Dynamic
Control (VDC) off indicator light ” (P.2-19).
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 slippery
surfaces and always drive carefully.
. Do not modify the vehicle ’ s suspension.
If suspension parts such as shock
absorbers, struts, springs, stabilizer bars, bushings and wheels are not
INFINITI recommended 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 INFINITI
recommended or are extremely deterio-
rated, the VDC system may not operate
properly and the VDC warning light
may illuminate.
. If engine control related parts are not
INFINITI 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 prop-
erly and the VDC warning light
may
illuminate. Do not drive on these types
of roads.
. When driving on an unstable surface
such as a turntable, ferry, elevator or
ramp, the VDC warning light
may
illuminate. This is not a malfunction.

2. Loosen each wheel nut one or two turns
by turning counterclockwise with the
wheel nut wrench. Do not remove the
wheel nuts until the tire is off the
ground.
3. Carefully raise the vehicle until the tire
clears the ground. To lift the vehicle,
securely hold the jack lever and rod
with both hands as shown above.
Remove the wheel nuts, and then
remove the tire. SCE0661
Installing the spare tire GUID-4746005A-8947-492C-A2AA-FAC1609582B5
The T-type spare tire is designed for
emergency use. (See specific instructions
under the heading “ Wheels and tires ” (P.8-
33).)
1. Clean any mud or dirt from the surface
between the wheel and hub.
2. Carefully put the spare tire on and
tighten the wheel nuts finger tight.
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.

[ Edit: 2012/ 1/ 17 Model: V36-D ]Tire rotation (Models equipped with
different size tires on front and
rear) GUID-42591FA5-788F-4ABA-B1AA-2564E2B3FCB6
Tires cannot be rotated on this
vehicle, as front tires are a different
size from 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 regard-
ing tires, refer to “ Important Tire
Safety Information ” (US) or “ Tire Safety Information ” (Canada) in
the Warranty Information Booklet.
