Check the fluid level in the reservoir. If the
brake fluid is below the MIN line
2, the brake
warning light will illuminate. Add brake fluid
up to the MAX line
1. Use Genuine INFINITI
brake fluid DOT4+ or equivalent. Never mix
different types of fluids. For additional infor-
mation on the recommended type of brake
fluid, refer "Recommended fluids/lubricants
and capacities" in the "9. Maintenance and
Schedules" section.
If the brake fluid must be added frequently,
the brake system should be thoroughly
checked. It is recommended that you visit an
INFINITI retailer for this service. Fill the windshield-washer fluid reservoir pe-
riodically. Add fluid when the low washer
fluid warning appears on the vehicle informa-
tion display.
To fill the windshield-washer fluid reservoir,
lift the cap off the reservoir and pour the
windshield-washer fluid into the reservoir
opening.
Add a washer solvent to the washer for bet-
ter cleaning. In the winter season, add a
windshield-washer antifreeze. Follow the
manufacturer’s instructions for the mixture
ratio.
Refill the reservoir more frequently when
driving conditions require an increased
amount of windshield-washer fluid.Recommended fluid is Genuine INFINITI
Windshield Washer Concentrate Cleaner &
Antifreeze or equivalent.CAUTION

coolant for window washer solution.
This may result in damage to the paint.
•Do not fill the window washer reservoir
tank with washer fluid concentrates at
full strength. Some methyl alcohol
based washer fluid concentrates may
permanently stain the grille if spilled
while filling the window washer reser-
voir tank.

•Keep the battery surface clean and dry.
Clean the battery with a solution of baking
soda and water.
•Make certain the terminal connections are
clean and securely tightened.
•If the vehicle is not used for 30 days or
longer, disconnect the
-negative battery
terminal cable to prevent discharge.
NOTE
Care should be taken to avoid situations
that can lead to potential battery discharge
and potential no-start conditions such as:
•Installation or extended use of electronic
accessories that consume battery power
when the engine is not running (Phone
chargers, GPS, DVD players, etc).
•Vehicle is not driven regularly and/or only
driven short distances.
In these cases, the battery may need to be
charged to maintain battery health.
WARNING
•Do not expose the battery to flames, an
electrical spark or a cigarette. Hydrogen
gas generated by the battery is explo-
sive. Explosive gases can cause blind-
ness or injury. Do not allow battery fluid
to contact your skin, eyes, fabrics or
painted surfaces. Sulfuric acid can cause
blindness or injury. After touching a bat-
tery or battery cap, do not touch or rub
your eyes. Thoroughly wash your hands.
If the acid contacts your eyes, skin or
clothing, immediately flush with water
for at least 15 minutes and seek medical
attention.
•Do not operate the vehicle if the fluid in
the battery is low. Low battery fluid can
cause a higher load on the battery which
can generate heat, reduce battery life,
and in some cases lead to an explosion.
•When working on or near a battery, al-
ways wear suitable eye protection and
remove all jewelry.
•Battery posts, terminals and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
•Keep battery out of the reach of chil-
dren.
•Do not tip the battery. Keep the vent
caps tight and the battery level.

REINITIALISATION PROCEDURE
AFTER BATTERY
RECONNECTION
If the battery has been reconnected, check
the following items:
•Clock setting (if so equipped). For details,
see "Clock" in the "2. Instruments and con-
trols" section, or the separately provided
navigation system Owner's Manual, or the
audio device descriptions in " Audio system
(if equipped)" in the "4. Display screen,
heater and air conditioner, and audio sys-
tem" section.
•Reset the desired radio stations to the pre-
set station buttons. For details, see the
audio device descriptions in the “4. Heater
and air conditioner, and audio system”.
JUMP-STARTING
If jump-starting is necessary, see "Jump
starting" in the "6. In case of emergency" sec-
tion. 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.
WARNING
Be sure the ignition switch is in the OFF
position before servicing drive belt. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs of un- usual wear, cuts, fraying or looseness. If
the belt is in poor condition or loose, have
it replaced or adjusted. It is recommended
that you visit an INFINITI retailer for this
service.
2. Have the belts checked regularly for con- dition and tension in accordance with the
maintenance schedule as shown in a
separately provided Warranty Informa-

Replace the spark plugs according to the
maintenance schedule shown in a separate
maintenance booklet.
If replacement is required, it is recommended
that you visit an INFINITI retailer.
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.

move the spark plugs. An incorrect
socket can cause damage to the spark
plugs. It is recommended that you visit an INFINITI
retailer if checking or replacement is required.
WARNING
•Operating the engine with the air
cleaner filter off can cause you or others
to be burned. The air cleaner filter not
only cleans the intake air, it also stops
the flame if the engine backfires. If the
air cleaner is not installed and the engine
backfires, you could be burned. Never
drive with the air cleaner filter off. Be
cautious working on the engine when
the air cleaner is off.
•Never pour fuel into the throttle body or
attempt to start the engine with the air
cleaner removed. Doing so could result
in serious injury.
CLEANING
If the windshield or rear window is not clear
after using the window 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 or rear
window with a washer solution or a mild
detergent. The windshield or rear window is
clean if beads do not form when rinsing with
clear water.
Clean the blade by wiping it with a cloth
soaked in a washer solution or a mild deter-
gent. Then rinse the blade with clear water. If
the windshield or rear window is still not clear
after cleaning the blades and using the wiper,
replace the blades.
CAUTION
Worn windshield wiper blades can damage
the windshield and impair driver vision.

glass; otherwise the arms may be dam-
aged from wind pressure. If you wax the surface of the engine hood, be
careful not to let wax get into the washer

the color and fuse rating. The fuse ratings are
listed in the fuse allocation chart.
If the newly inserted fuse also blows, have
the cause traced and rectified. It is recom-
mended you visit an INFINITI retailer for this
service.
The fuses in your vehicle disconnect faulty
circuits. if a fuse blows, all the components on
the circuit and their functions will fail.
BEFORE REPLACING A FUSE
•Secure the vehicle against rolling away.
•Switch off all electrical consumers.
•Remove the key from the ignition lock.
The fuses are located in various fuse boxes:
•Fuse box in the engine compartment on
the left-hand side of the vehicle, when
viewed in the direction of travel.
•Fuse box in the front-passenger footwell.
The fuse allocation chart is on the fuse box in
the front-passenger footwell.
