WARNINGAntifreeze is poisonous and should be stored
carefully in marked containers out of the reach
of children.
Fill the window washer fluid reservoir periodi-
cally. Add window washer fluid when the low
window washer fluid warning light comes on.
To fill the window washer fluid reservoir, lift the
cap off the reservoir tank and pour the window
washer fluid into the tank opening.
Add a washer solvent to the washer for better
cleaning. In the winter season, add a wind-
shield washer antifreeze. Follow the manufac-
turer’s instructions for the mixture ratio. Refill the reservoir more frequently when driv-
ing conditions require an increased amount of
window washer fluid.
Recommended fluid is Genuine NISSAN Wind-
shield Washer Concentrate Cleaner & Antifreeze
or equivalent.
CAUTION● Do not substitute engine anti-freeze 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 win-
dow washer reservoir tank.
● Pre-mix washer fluid concentrates with wa-
ter to the manufacturer’s recommended lev-
els before pouring the fluid into the window
washer reservoir tank. Do not use the win-
dow washer reservoir tank to mix the washer
fluid concentrate and water. ● 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 to be used for 30 days or
longer, disconnect the negative (  ) battery
terminal cable to prevent discharging it.
COUPE CAUTIONWhen the battery cable is removed from the
battery terminal, do not close either of front
doors. The automatic window adjusting func-
tion will not work, and the side roof panel may
be damaged.
To disconnect the negative (  ) battery terminal,
perform the procedure in the following order.
Otherwise, the window and the side roof panel
may contact and be damaged.
1. Close the windows.
2. Open the hood.
3. Close and lock all the doors.
4. Disconnect the negative (  ) battery termi-
nal.

To connect the negative (  ) battery terminal,
perform the procedure in the following order.
Otherwise, the window and the side roof panel
may contact and be damaged.
1. Unlock and open the driver side door. Do
not close the door.
2. Open the hood.
3. Connect the negative (  ) battery terminal.
Then close the hood.
4. Fully open the driver side door window.
5. Close the driver side door and the win-
dow.
SEDAN AND COUPE WARNING● Do not expose the battery to flames or elec-
trical sparks. Hydrogen gas generated by
the battery is explosive. Do not allow battery
fluid to contact your skin, eyes, fabrics, or
painted surfaces. After touching a battery or
battery cap, do not touch or rub your eyes.
Thoroughly wash your hands. If the acid con-
tacts your eyes, skin or clothing, immedi-
ately 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 gener-
ate heat, reduce battery life, and in some
cases lead to an explosion.
● When working on or near a battery, always
wear suitable eye protection and remove all
jewelry.
● Battery posts, terminals and related acces-
sories contain lead and lead compounds.
Wash hands after handling.
● Keep the battery out of the reach of children.
Check the fluid level in each cell (Remove the
battery cover if it is necessary). It should be
between the UPPER LEVEL
 1
and LOWER LEVEL
 2
lines.
If it is necessary to add fluid, add only distilled
water to bring the level to the indicator in each
filler opening. Do not overfill. DI0137MA

1. Remove the cell plugs
 A
.
2. Add distilled water up to the UPPER LEVEL
 1
line.
If the side of the battery is not clear, check
the distilled water level by looking directly
above the cell; the condition
 1
indicates
OK and the conditions
 2
needs more to be
added.
3. Tighten cell plugs
 A
.
Vehicles operated in high temperatures or un-
der severe conditions require frequent checks
of the battery fluid level. JUMP STARTING If jump starting is necessary, see “JUMP START-
ING” in the “6. In case of emergency” section. If
the engine does not start by jump starting, the
battery may have to be replaced. Contact an
INFINITI retailer. CAUTION● Do not ground accessories directly to the
battery terminal. Doing so will bypass the
variable voltage control system and the ve-
hicle battery may not charge completely.
● Use electrical accessories with the engine
running to avoid discharging the vehicle
battery.
The variable voltage control system measures
the amount of electrical discharge from the
battery and controls voltage generated by the
generator.SDI1480C

REPLACING SPARK PLUGS If replacement is required, see an INFINITI re-
tailer for servicing.
Iridium-tipped spark plugs It is not necessary to replace the iridium-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much
longer. Follow the maintenance schedule in
“INFINITI Service and Maintenance Guide”, but
do not reuse them by cleaning or regapping.
Always replace spark plugs with recommended
or equivalent ones. Remove the retainers
 1
as illustrated and pull
out the filter element
 2
.
The filter element should not be cleaned and
reused. Replace it according to the mainte-
nance intervals. See “INFINITI Service and Main-
tenance Guide” for maintenance intervals. When replacing the filter, wipe the inside of the
air cleaner housing and the cover with a damp
cloth.
WARNING● Operating the engine with the air cleaner
removed can cause you or others to be
burned. The air cleaner not only cleans the
air, it stops flame if the engine backfires. If it
isn’t there, and the engine backfires, you
could be burned. Do not drive with the air
cleaner removed, and be careful when work-
ing on the engine with the air cleaner
removed.
● Never pour fuel into the throttle body or at-
tempt to start the engine with the air cleaner
removed. Doing so could result in serious
injury.SDI2020

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 wind-
shield 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 deter-
gent. Then rinse the blade with clear water. If
your windshield is still not clear after cleaning
the blades and using the wiper, replace the
blades.
Worn windshield wiper blades can damage the
windshield and impair driver vision.
REPLACING Replace the wiper blades if they are worn.
1. Pull the wiper arm.
2. Push the release tab
 A
, and then move
the wiper blade down the wiper arm
 1
while pushing the release tab to remove.
3. Insert the new wiper blade onto the wiper
arm until a click sounds.
4. Rotate the wiper blade so the dimple is in
the groove. 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 arm may be damaged
from wind pressure. SDI2048

If you wax the surface of the hood, be careful
not to let wax get into the washer nozzle
 A
.
This may cause clogging or improper wind-
shield washer operation. If wax gets into the
nozzle, remove it with a needle or small pin
 B
.
Be careful not to damage the nozzle. 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.
WARNINGSee 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. For additional information, see the main-
tenance log section of your “INFINITI Service
and Maintenance Guide” for maintenance inter-
vals.
