INFINITI QX 2010 Owners Manual

If the brakes do not operate properly, have the
brakes checked by an INFINITI dealer.
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
See an INFINITI dealer for a brake system
check 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 re-
placement, a high pitched scraping or screech-
ing 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, occa-
sional 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 Ser-
vice and Maintenance Guide” booklet for mainte-
nance intervals.

Two types of fuses are used. TypeAis used in
the fuse boxes in the engine compartment. Type
Bis used in the passenger compartment fuse
box.
Type A fuses are provided as spare fuses. They
are stored in the passenger compartment fuse
box.
Type A fuses can be installed in the engine com-
partment and passenger compartment fuse
boxes. If a type A fuse is used to replace a type B fuse,
the type A fuse will not be level with the fuse
pocket as shown in the illustration. This will not
affect the performance of the fuse. Make sure the
fuse is installed in the fuse box securely.
Type B fuses cannot be installed in the under-
hood fuse boxes. Only use type A fuses in the
underhood fuse boxes.

electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse. 1. Be sure the ignition switch and the headlight switch are OFF.
2. Open the engine hood.

Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) this device
must accept any interference received, in-
cluding interference that may cause undes-
ired operation of the device.HEADLIGHTS
Replacing the xenon headlight bulb
(Low-beam)
If replacement is required, see an INFINITI dealer.
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 head-
lights replaced at an INFINITI dealer. For
additional information, see “Headlight
and turn signal switch” in the “Instru-
ments and controls” section.
Replacing the halogen headlight bulb
(High-beam)
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. Be-
cause the headlight assembly must be removed
from the vehicle for bulb replacement, see your
INFINITI dealer.
CAUTION
●High pressure halogen gas is sealed
inside the halogen bulb. The bulb may
break if the glass envelope is scratched
or the bulb is dropped.
● When handling the bulb, do not touch
the glass envelope.
● DO NOT TOUCH THE BULB WITH BARE
HANDS.
● Use the same number and wattage as
shown in the chart.
● Do not leave the bulb out of the head-
light reflector for a long period of time
as dust, moisture and smoke may enter
the headlight body and affect the per-
formance of the headlight.
● Aiming is not necessary after replacing
the bulb. When aiming adjustment is
necessary, contact an INFINITI dealer.
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 dealer.
