8-12Maintenance and do-it-yourself

WARNING
∙ Use only new fluid from a sealed con-tainer. Old, inferior or contaminated fluid
may damage the brake system. The use of
improper fluids can damage the brake
system and affect the vehicle’s stopping
ability.
∙ Clean the filler cap before removing.
∙ Brake fluid is poisonous and should be stored carefully in marked containers out
of reach of children.
CAUTION
Do not spill the fluid on any painted sur-
faces. This will damage the paint. If fluid is
spilled, immediately wash the surface with
water.
Check the fluid level in the reservoir. If the
brake fluid is below the MIN line
B, the brake
warning light will illuminate. Add brake fluid
up to the MAX line
A. For additional infor-
mation on the recommended type of brake
fluid, refer to “Recommended fluids/
lubricants and capacities” in the “Technical
and consumer information” section of this
manual.
If the brake fluid must be added frequently,
the brake system should be thoroughly
checked by an INFINITI retailer.
For additional information on the location of
the brake fluid reservoir, refer to “Engine
compartment check locations” in this section.

2. Check the fluid level in each cell. If it isnecessary to add fluid, add only distilled
water to bring the level up to the bottom
of the filler opening. Do not overfill.Re-
install the vent caps. Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.
JUMP STARTING
If jump starting is necessary, refer to “Jump
starting” in the “In case of emergency” section
of this manual. If the engine does not start by
jump starting, the battery may have to be
replaced. It is recommended that you visit an
INFINITI retailer for this service.

have it replaced or adjusted. It is recom-
mended that you visit an INFINITI re-
tailer for this service.

the maintenance schedule found in your
“INFINITI Service and Maintenance
Guide”.
REPLACING SPARK PLUGS
Iridium-tipped spark plugs
It is not necessary to replace iridium-tipped
Aspark plugs as frequently as conventional
type spark plugs because they last much lon-
ger. Follow the maintenance log shown in the
“INFINITI Service and Maintenance Guide”.
Do not service iridium-tipped spark plugs by
cleaning or regapping.
∙ Always replace spark plugs with recom-
mended or equivalent ones.
WARNING
Be sure the engine and ignition switch are
off and that the parking brake is engaged
securely.
CAUTION
Be sure to use the correct socket to remove
the spark plugs. An incorrect socket can
damage the spark plugs.
If replacement is required, it is recommended
that you visit an INFINITI retailer for this
service.

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.

ENGINE COMPARTMENT
CAUTION
Never use a fuse of higher or lower amper-
age rating than that specified on the fuse

check for an open fuse. 1. Be sure the ignition switch and the head- light switch are OFF.
2. Open the engine hood. 3. Remove the fuse box cover by pushing
the tab and lifting the cover up.
4. Remove the fuse with the fuse puller. The fuse puller is located in the fuse
block in the passenger compartment. 5. If the fuse is open

INFINITI retailer.
Fusible links
If the electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace with only Genuine NISSAN
parts.
