INFINITI FX 2012 Owners Manual

8-24Maintenance and do-it-yourself
Contact an INFINITI retailer if checking or
replacement is required.If the brakes do not operate properly, have
the brakes checked by an INFINITI retailer.
SELF-ADJUSTING BRAKES
Your vehicle is equipped with self-adjust-
ing brakes.
The disc-type brakes self-adjust every time
the brake pedal is applied.
WARNING
See an INFINITI retailer for a brake system
check if the brake pedal height does not
return to normal.
BRAKE PAD WEAR WARNING
The disc brake pads have audible wear
warnings. When a brake pad requires
replacement, it will make a high pitched
scraping sound when the vehicle is in
motion. This scraping sound will first occur
only when the brake pedal is depressed.
After more wear of the brake pad, the
sound will always be heard even if the
brake pedal is not depressed. Have the
brakes checked as soon as possible if the
wear warning sound is heard.
Under some driving or climate conditions,occasional 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 the maintenance log section of your
“INFINITI Service and Maintenance Guide”
for maintenance intervals.

Extended storage switch (if so
equipped)
To reduce battery drain, the extended
storage switch comes from the factory
switched off. Prior to delivery of your
vehicle, the switch is pushed in (switched
on) and should always remain on.
If any electrical equipment does not
operate, remove the extended storage
switch and check for an open fuse.
NOTE:
If the extended storage switch malfunc-
tions, or if the fuse is open, it is not
necessary to replace the switch. In this

case, remove the extended storage switch
and replace it with a new fuse of the same
rating.
How to remove the extended storage
switch:
1. To remove the extended storage switch,be sure the ignition switch is in the OFF
or LOCK position.
2. Be sure the headlight switch is in the OFF position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
*1found on
each side of the storage switch.
5. Pull the storage switch straight out from the fuse box

CAUTION
Be careful not to allow children to swallow
the battery and removed parts.

3. Replace the battery with a new one.
Recommended battery: CR2032 or
equivalent.
.Do not touch the internal circuit andelectric terminals as it could cause a
malfunction.
.Hold the battery by the edges.
Holding the battery across the con-
tact points will seriously deplete the
storage capacity.
.Make sure that the + side faces thebottom of the case.SDI2452

HEADLIGHTS
Replacing
Fog may temporarily form inside the lens of
the exterior lights in the rain or in a car
wash. A temperature difference between
the inside and the outside of the lens
causes the fog. This is not a malfunction. If
large drops of water collect inside the lens,
contact an INFINITI retailer.
Xenon headlight bulb (if so equipped):
If replacement is required, see an INFINITI
retailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they pro-
duce a high voltage. To prevent an electric
shock, never attempt to modify or disas-
semble. Always have your xenon headlights
replaced at an INFINITI retailer. For addi-
tional information, see “Headlight and turn
signal switch” (P.2-36).

TIRE PRESSURE
Tire Pressure Monitoring System
(TPMS)
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.
The TPMS will activate only when the
vehicle is driven at speeds above 16 MPH
(25 km/h). Also, this system may not
detect a sudden drop in tire pressure (for
example a flat tire while driving).
For more details, see “Low tire pressure
warning light” (P.2-15),“Tire Pressure
Monitoring System (TPMS)” (P.5-4) and
“Tire Pressure Monitoring System (TPMS)”
(P.6-2).
Tire inflation pressure
Check the pressure of the tires
(including the spare) often and al- ways prior to long distance trips. The
recommended tire pressure specifi-
cations are shown on the Tire and
Loading Information label under the
“Cold Tire Pressure”
heading. The
Tire and Loading Information label is
affixed to the driver side center pillar.
Tire pressures should be checked
regularly because:
.Most tires naturally lose air over time.
.Tires can lose air suddenly whendriven over potholes or other
objects or if the vehicle strikes a
curb while parking.
The tire pressures should be checked
when the tires are cold. The tires are
considered COLD after the vehicle
has been parked for 3 or more hours,
or driven less than 1 mile (1.6 km) at
moderate speeds.
Incorrect tire pressure, including
under inflation, may adversely affect
tire life and vehicle handling.
WHEELS AND TIRES

WARNING
.Improperly inflated tires can fail
suddenly and cause an accident.
. The Gross Vehicle Weight rating
(GVWR) is located on the F.M.V.S.
S./C.M.V.S.S. certification label.
The vehicle weight capacity is
indicated on the Tire and Loading
Information label. Do not load
your vehicle beyond this capacity.
Overloading your vehicle may re-
sult in reduced tire life, unsafe
operating conditions due to pre-
mature tire failure, or unfavorable
handling characteristics and could
also lead to a serious accident.
Loading beyond the specified ca-
pacity may also result in failure of
other vehicle components.
. 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.
. For additional information regard-
ing tires, refer to “Important Tire
Safety Information ”(US) or “Tire
Safety Information ”(Canada) in
the Warranty Information Booklet.
