CLEANING
If your windshield is not clear after using the
windshield washer or if a wiper blade chatters
when running, wax or other material may be on
the blade or windshield.
Clean the outside of the windshield with a washer
solution or a mild detergent. Your windshield is
clean if beads do not form when rinsing with clear
water.
Clean each blade by wiping it with a cloth soaked
in a washer solution or a mild detergent. Then
rinse the blades with clear water. If your wind-
shield is still not clear after cleaning the blades
and using the wiper, replace the blades.
CAUTION
Worn windshield wiper blades can dam-
age the windshield and impair driver
vision.
REPLACING
Replace the wiper blades if they are worn.1. Lift the wiper arm away from the windshield.
2Push the release tab, then move the wiper
blade down the wiper arm to remove.
3Remove the wiper blade.
4. Insert the new wiper blade onto the wiper arm until it clicks into place.
5. Rotate wiper blade so the dimple is in the groove. 6. Return the wiper to its original position and
release it until it has made contact with the
windshield.
CAUTION
●After wiper blade replacement, return
the wiper arm to its original position;
otherwise it may be damaged when the
hood is opened.
● Make sure the wiper blades contact the
glass; otherwise the arms may be dam-
aged from wind pressure.

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.

Never use a fuse of a higher or lower
amperage rating than specified on the

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.
