2003 INFINITI G35 brake pads

control off switch is pushed to OFF. This
indicates the vehicle dynamics control system
and traction control system are not operating.
When the vehicle dynamics control off indica-
tor light and slip indicator light come on with
the vehicle dynamics control system turned
on, this light alerts the driver to the fact that the
vehicle dynamics control system's fail-safe
mode is operating, i.e. the vehicle dynamics
control system may not be functioning prop-
erly. Have the system checked by your
INFINITI retailer. If an abnormality occurs in
the system, the vehicle dynamics control sys-
tem function will be canceled but the vehicle is
still driveable. For additional information, see
ªVehicle dynamics control system (VDC)º in
the ª5. Starting and drivingº section of this
manual.
Turn signal/hazard indicator
lightsThe light flashes when the turn signal switch
lever or hazard switch is turned on.
AUDIBLE REMINDERS
Key reminder chime The chime will sound if the driver's side door is
opened while the key is left in the ignition
switch (ignition switch is turned off). Remove the key and take it with you when leaving the
vehicle.
Light reminder chime The chime will sound when the front door is
opened with the headlight switch on unless the
ignition key is in the ON position.
Make sure to turn the light switch off when you
leave the vehicle.
Brake pad wear warning The disc brake pads have audible wear warn-
ings. When a brake pad requires replacement,
it will make a high pitched scraping sound
when the vehicle is in motion whether or not
the brake pedal is depressed. Have the brakes
checked as soon as possible if the warning
sound is heard. Your vehicle has two types of security sys-
tems, as follows:
O Vehicle Security System
O Infiniti Vehicle Immobilizer System
The security condition will be shown by the
security indicator light.
VEHICLE SECURITY SYSTEM The vehicle security system provides visual
and audio alarm signals if parts of the vehicle
are disturbed.SECURITY SYSTEMS

O HEADED UPHILL WITH CURB:
j 2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
O HEADED UPHILL OR DOWNHILL, NO
CURB:
j 3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
4. Turn the ignition key to the LOCK position
and remove the key. The power assisted steering is designed to
use 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 or at low speeds.
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
much harder to operate. BRAKING PRECAUTIONS The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brake
The brake booster aids braking by using en-
gine 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 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.
Using the brakes
Avoid resting your foot on the brake pedal
while driving. This overheats the brakes, in-
creases wear on the brake linings and pads,
and reduces gas mileage.POWER STEERING BRAKE SYSTEM

WARNINGSee your INFINITI retailer and have it
checked if the brake pedal height does
not return to normal.
Brake pad wear indicators The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, it will make a high
pitched scraping or screeching sound when
the vehicle is in motion whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indi-
cator sound is heard.
Under some driving or climate conditions, oc-
casional brake squeak, squeal or other noise
may be heard. Occasional brake noise during
light to moderate stops is normal and does not
affect the function or performance of the brake
system.
Proper brake inspection intervals should
be followed. For additional information, see
ªPeriodic maintenance schedulesº in the ª9.
Maintenanceº section for maintenance inter-
vals. High performance sports brake pad occasion-
ally makes squeak, squeal or other braking
noise because of its very high friction coeffi-
cient.
These occasional brake noise is normal, but if
it continues, see your INFINITI retailer.
BRAKE BOOSTER Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) re-
mains the same from one pedal application
to the next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a
little.
3. With the brake pedal depressed, stop the
engine. Keeping the pedal depressed for
about 30 seconds, the pedal height should
not change.
4. Run the engine for one minute without
depressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradu-
ally with each depression as the vacuum is
released from the booster. If the brakes do not operate properly, see your
INFINITI retailer.

EXPLANATION OF MAINTENANCE
ITEMS Additional information on the following
items with ª*º is found in the ª8. Do-it-
yourselfº section.
Emission control system
maintenance Drive belts*: Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filter: Under normal driving con-
ditions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
EVAP vapor lines: Check vapor lines and
connections for failure or looseness. If leaks
are found, replace them.
Fuel lines: Check the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Engine coolant*: Drain and flush the cooling
system.
Engine oil & oil filter*: Under normal driving conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*: Replace with new plugs having
the correct heat range.
Chassis and body maintenance Brake lines & cables: Check the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.
Brake pads & rotors: Check these and the
other neighboring brake components for wear,
deterioration and leaks. Under severe driving
conditions, they may have to be inspected
more frequently.
Automatic transmission fluid*: Using auto-
matic transmission fluid other than Genuine
Nissan ATF Matic Fluid J will cause deteriora-
tion in driveability and automatic transmission
durability, and may damage the automatic
transmission, which is not covered by the
INFINITI new vehicle limited warranty. If
checking or replacement is required, we rec-
ommend your INFINITI retailer for servicing.
Under severe driving conditions, the fluid should be replaced at the specified interval.
Manual transmission oil & differential gear
oil*: Check the oil level and visually inspect for
signs of leakage.
Under severe driving conditions, the oil should
be replaced at the specified interval.
Steering gear & linkage, axle & suspension
parts: Check for damage, looseness and leak-
age of oil or grease. Under severe driving
conditions, more frequent inspection should be
performed.
Exhaust system: Visually check the exhaust
pipes, muffler, and hangers for proper attach-
ment, leaks, cracks, chafing, abrasion, dete-
rioration, etc. Under severe driving conditions,
inspection should be performed more fre-
quently.
In-cabin microfilter: Under normal condi-
tions, this microfilter should be replaced in
accordance with the maintenance schedule.
However, in some situations, the microfilter
may clog more rapidly (depending on the air
conditioner's working environment). If this hap-
pens, the air flow may decrease, or the win-
dows may fog up easily when the air condi-
tioner is in use, the microfilter should be
replaced immediately at your INFINITI retailer.
