fect the vehicle’s stopping ability.
● Be sure to clean the filler cap before
removing.
● Brake fluid is poisonous and should be
stored carefully in marked containers out of
the reach of children.

Contact an INFINITI retailer if checking or re-
placement 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-adjusting
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 warn-
ings. 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 warn-
ing 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 sys-
tem.
Proper brake inspection intervals should be fol-
lowed.

tenance log section of your “INFINITI Service
and Maintenance Guide” for maintenance inter-
vals.

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 re-
tailer.
WARNING
HIGH VOLTAGE
When xenon headlights are on, they produce a
high voltage. To prevent an electric shock,
never attempt to modify or disassemble. Al-
ways have your xenon headlights replaced at
an INFINITI retailer. For additional information,
see “HEADLIGHT AND TURN SIGNAL SWITCH” in
the “2. Instruments and controls” section.Halogen headlight bulb (if so equipped) :
The headlight is a semi-sealed beam type which
uses a replaceable headlight (halogen) bulb. If
replacement is required, see an INFINITI retailer
for servicing.
CAUTION
●
High pressure halogen gas is sealed inside
the bulb. The bulb may break if the glass
envelope is scratched or the bulb is dropped.
● Only touch the plastic base when handling
the bulb. Never touch the glass envelope.
Touching the glass could significantly affect
bulb life and/or headlight performance.
● Do not leave the bulb out of the headlight
reflector for a long period of time as dust,
moisture, and smoke may enter the head-
light body and affect the performance of the
headlight.
● Aiming is not necessary after replacing the
bulb. When aiming adjustment is necessary,
contact an INFINITI retailer.
