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.

BRAKE ASSIST GUID-0BC62A24-2073-43FC-B791-6C3D51778617
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.
WARNINGThe 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.
PREVIEW FUNCTION (Intelligent
Cruise Control system equipped
models) GUID-BC7D2384-44AA-4BCF-9239-DF7DEC96A526
When the Preview Function identifies the
need to apply emergency braking by
sensing a vehicle ahead in the same lane
and the distance and relative speed from
it, it applies the brake pre-pressure before
the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play. . This system will not operate when the
vehicle is moving at approximately 20
MPH (32 km/h) or less.
. The pre-pressure function ceases when
the following conditions are met:
1) When the driver depresses the
accelerator pedal or the brake
pedal.
2) If the driver does not operate the
accelerator or brake pedal within
approximately 1 second. SSD0338
. The sensor will not detect:
1) Pedestrians or objects in the road-
way
2) Oncoming vehicles in the same lane
3) Motorcycles traveling offset in the
travel lane as illustrated

. As there is a performance limit to the
Preview Function, never rely solely on
this system. This system does not
correct careless inattentive or absent-
minded driving, or overcome poor visi-
bility in rain, fog, or other bad weather.
Reduce vehicle speed by depressing the
brake pedal, in order to maintain a safe
distance between vehicles.
. The system may not detect the vehicle in
front of you in certain road or weather
conditions. The Preview Function may
not operate properly under the following
conditions. The vehicle is still driveable
under normal conditions and the Brake
Assist will operate.
— When rain, snow or dirt adhere to
the system sensor
— When strong light (for example, at
sunrise or sunset) is directly shining
on the front of the vehicle
— Winding or hilly roads may cause
the sensor to temporarily not detect
a vehicle in the same lane or may
detect objects or vehicles in other
lanes. — Vehicle position in the lane may
cause the sensor to temporarily not
detect a vehicle in the same lane or
may detect objects or vehicles in
other lanes.

When the Preview Function is not operating
properly, a chime sounds and the system
warning light (orange) will come on.
Action to take: GUID-D73A39BF-43C8-459F-9C24-47B7F579C407
If the warning light comes on, park the
vehicle in a safe place. Turn the engine off,
restart the engine and resume driving.
If the indicator stays on, it may indicate
that the Preview Function is malfunction-
ing (the brake is operative). Although the
Vehicle is still driveable under normal
conditions, have the vehicle checked at
an INFINITI retailer.

[ Edit: 2012/ 1/ 17 Model: V36-D ]WARNINGDo not pump the brake pedal. Doing so may
result in increased stopping distances.
Self-test feature GUID-EC96AE96-D9F6-4F19-A5A9-937C4D6337A4
The ABS includes electronic sensors, elec-
tric 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 pulsa-
tion in the brake pedal. This is normal and
does not indicate 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 operates normally,
but without anti-lock assistance.
If the ABS warning light illuminates during
the self-test or while driving, have the
vehicle checked by an INFINITI retailer. Normal operation GUID-36C3BA08-72B5-4E9B-96CF-93CCD7FE6655
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. How-
ever, the pulsation may indicate that road
conditions are hazardous and extra care is
required while driving. GUID-B2222C83-77D9-46CF-971F-591ADE2397C3
The Vehicle Dynamic Control (VDC) system
uses various sensors to monitor driver
inputs and vehicle motion. Under certain
driving conditions, 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 func-
tion).
. 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 condi-
tions).
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

. 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.
Restart the engine after driving onto a

. If wheels or tires other than the INFINITI
recommended ones are used, the VDC
system may not operate properly and
the VDC warning light
may illumi-
nate.
. The VDC system is not a substitute for
winter tires or tire chains on a snow
covered road. GUID-5A0B024F-3785-40BC-BF28-384D2975453D
The 4 Wheel Active Steer (4WAS) system is
an electronically controlled four-wheel
steering system.
Depending on the vehicle speed and
steering angle, the angles of the front
and rear wheels are adjusted by the 4WAS
system to help improve driving perfor-
mance.
If a malfunction occurs in the system, the
4WAS function will stop but the ordinary
two-wheel steering system will operate
normally. The “ 4WAS ” warning light will
illuminate. If the light illuminates while you
are driving, contact an INFINITI retailer for
repair.
The steering wheel may be slightly turned
even when driving on a straight road due to
a protection mechanism for the 4WAS
system. This is not a malfunction. The
steering wheel will return to the normal
position after the protection mechanism
deactivates.
The protection mechanism activates under
the following conditions:
. The steering wheel is operated forcibly
when it is hard to operate or the tires
are blocked by obstacles.
. The steering wheel is continuously
operated when the vehicle is parked or being driven at extremely low speed.
. The steering wheel is forcibly turned
beyond its operation limits.
. The battery voltage is reduced.
Repeated steering maneuvers that may
activate the protection mechanism will
damage the 4WAS system.
WARNING The 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving tech-
niques. Ultimately the responsibility for
safety of self and others rests in the hands
of the driver. Therefore only through atten-
tive and careful driving methods can the
4WAS system be fully appreciated and
safety optimized.

TIRE PRESSURE MONITORING SYS-
TEM (TPMS) GUID-EFDE8E6D-AFA0-4243-A90D-0D01CCEE6814
This vehicle is equipped with the Tire
Pressure Monitoring System (TPMS). It
monitors tire pressure of all tires except
the spare. When the low tire pressure
warning light is lit and the CHECK TIRE
PRESSURE warning appears on the dot
matrix liquid crystal display, one or more
of your tires is significantly under-inflated.
If the vehicle is being driven with low tire
pressure, the TPMS will activate and warn
you of it by the low tire pressure warning
light. This system will activate only when
the vehicle is driven at speeds above 16
MPH (25 km/h). For more details, see
“ Warning/indicator lights and audible re-
minders ” (P.2-12) and “ Tire Pressure Mon-
itoring System (TPMS) ” (P.5-4).
WARNING . If the low tire pressure warning light
illuminates while driving, avoid sudden
steering maneuvers or abrupt braking,
reduce vehicle speed, pull off the road to
a safe location and stop the vehicle as
soon as possible. Driving with under-
inflated tires may permanently damageROADSIDE ASSISTANCE PROGRAM EMERGENCY ENGINE SHUT OFF FLAT TIRE

tire failure. Serious vehicle damage
could occur and may lead to an accident
and could result in serious personal
injury. Check the tire pressure for all
four tires. Adjust the tire pressure to the
recommended COLD tire pressure shown
on the Tire and Loading Information
label to turn the low tire pressure
warning light OFF. If the light still
illuminates while driving after adjusting
the tire pressure, a tire may be flat. If
you have a flat tire, replace it with a
spare tire as soon as possible.
. When a spare tire is mounted or a wheel
is replaced, the TPMS will not function
and the low tire pressure warning light
will flash for approximately 1 minute.
The light will remain on after 1 minute.
Contact your INFINITI retailer as soon as
possible for tire replacement and/or
system resetting.
. Replacing tires with those not originally
specified by INFINITI could affect the
proper operation of the TPMS.
. Do not inject any tire liquid or aerosol
tire sealant into the tires, as this may
cause a malfunction of the tire pressure sensors.

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 GUID-836955BF-390D-4BD9-A9ED-E82B3D771DEA
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 dishwash-
ing liquid mixed with clean, lukewarm
(never hot) water.
CAUTION . Do not use car washes that use acid in
the detergent. Some car washes, espe-
cially brushless ones, use some acid for
cleaning. The acid may react with some
plastic vehicle components, causing
them to crack. This could affect their
appearance, and also could cause them
not to function 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 deter-
gents, gasoline or solvents.
. Do not wash the vehicle in direct sun-
light 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 substances so the
paint surface is not scratched or da-
maged.
Rinse the vehicle again 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 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.
WAXING GUID-71C0704F-ABE3-4DDE-BBA8-904E37FD8A86
Regular waxing protects the paint surface
and helps retain new vehicle appearance.
Polishing is recommended to remove built-
up wax residue and to avoid a weathered
appearance before reapplying wax.
An INFINITI retailer can assist you in
choosing the proper product.CLEANING EXTERIOR
