TIRE PRESSURE MONITORING
SYSTEM (TPMS) (if so equipped)
This vehicle is equipped with the Tire Pres-
sure Monitoring System (TPMS). It monitors
tire pressure of all tires except the spare.
When the low tire pressure warning light is lit,
and the “Tyre Pressure Low - Add Air” warn-
ing appears in the vehicle information display,
one or more of your tires is significantly
under-inflated. If equipped, the system also
displays pressure of all tires (except the spare
tire) on the display screen by sending a signal
from a sensor that is installed in each wheel. If
the vehicle is being driven with low tire pres-
sure, 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 25 km/h (16 mph).
For additional information, refer to “Warning
lights, indicator lights and audible reminders”
in the “Instruments and controls” section and
“Tire Pressure Monitoring System (TPMS)” in
the “Starting and driving” section of this
manual.
WARNING
∙ Radio waves could adversely affect elec-tric medical equipment. Those who use a
pacemaker should contact the electric
medical equipment manufacturer for the
possible influences before use.
∙ If the low tire pressure warning light illu- minates 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 damage
the tires and increase the likelihood of
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 recom-
mended COLD tire pressure shown on
the tire placard to turn the low tire pres-
sure warning light OFF. If you have a flat
tire, replace it with a spare tire as soon as
possible. ∙ When replacing a wheel without TPMS
such as the spare tire, TPMS will not
function and the low tire pressure warn-
ing light will flash for approximately
1 minute. The light will remain on after
1 minute. Have your tires replaced
and/or TPMS system reset as soon as
possible. It is recommended that you visit
an INFINITI retailer for these services.
∙ 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.
CHANGING A FLAT TIRE
If you have a flat tire, follow the instructions
below:
Stopping the vehicle
1. Safely move the vehicle off the road and away from traffic.
2. Turn on the hazard warning flashers.
3. Park on a level surface and apply the parking brake. Move the shift lever to
P (Park).
4. Turn off the engine.

CHECKING BRAKE PEDAL
With the engine running, check the distanceA
between the upper surface of the pedal and
the metal floor. If it is out of the range shown,
it is recommended that you visit an INFINITI
retailer for service.
Distance A: Under depression force of
490 N (110 lbs)
90 mm (3 1/2 in) or more
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes. The front and rear disc-type brakes self-
adjust every time the brake pedal is applied.
WARNING
Have your brake system checked if the
brake pedal height does not return to nor-
mal. It is recommended that you visit an
INFINITI retailer for this service.
Brake pad wear indicators
The disc brake pads on your vehicle have
audible wear indicators. When a brake pad
requires replacement, a high pitched scraping
or screeching sound will be heard when the
vehicle is in motion. The noise will be heard
whether or not the brake pedal is depressed.
Have the brakes checked as soon as possible
if the wear indicator 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 regard-
ing brake inspections, refer to the appropri-
ate maintenance schedule information in the
“INFINITI Service and Maintenance Guide”.
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) remains 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. Keep 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 de-
crease gradually with each depression as
the vacuum is released from the booster.
If the brakes do not operate properly, have
the brakes checked. It is recommended that
you visit an INFINITI retailer for this service.

Maintenance and do-it-yourself8-23

The wheel nuts must be kept tightened to
specifications at all times. It is recommended
that wheel nuts be tightened to specification
at each tire rotation interval.
WARNING
∙ After rotating the tires, check and adjustthe tire pressure.
∙ Retighten the wheel nuts when the ve- hicle has been driven for 1,000 km
(600 miles) (also in cases of a flat tire,
etc.).
∙ Do not include the spare tire in the tire rotation.
∙ Incorrect tire selection, fitting, care or maintenance can affect vehicle safety
with risk of accident and injury.
∙ If in doubt, consult an INFINITI retailer or the tire manufacturer.
∙ Improperly inflated tires can fail sud- denly and cause an accident.
∙ Before taking a long trip, or whenever you heavily load your vehicle, use a tire
pressure gauge to ensure that the tire
pressures are at the specified level.
Tire wear and damage
1. Wear indicator
2. Location mark
WARNING
∙ Tires should be periodically inspected forwear, cracking, bulging or objects caught
in the tread. If excessive wear, cracks,
bulging or deep cuts are found, the tire(s)
should be replaced.
∙ The original tires have built-in tread wear indicators. When the wear indicators are
visible, the tire(s) should be replaced.
∙ Tires degrade with age and use. Have tires, including the spare, over 6 years old
checked by a qualified technician because
some tire damage may not be obvious.
Replace the tires as necessary to prevent
tire failure and possible personal injury.
∙ Improper service of the spare tire may result in serious personal injury. If it is
necessary to repair the spare tire, con-
tact an INFINITI retailer.
Replacing wheels and tires
When replacing a tire, use the same size,
tread design, speed rating and load carrying
capacity as originally equipped. For addi-
tional information, refer to “Wheels and tires”
in the “Technical and consumer information”
section of this manual.
