Fill the window washer fluid reservoir
periodically. Add window washer fluid
when the low washer fluid warning comes
on.
To fill the window washer fluid reservoir,
lift the cap and pour the window washer
fluid into the reservoir opening.
Add a washer solvent to the washer for
better 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 window washer fluid.
WINDOW WASHER FLUID

Recommended fluid is Genuine NISSAN
Windshield 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 window washer reser-
voir tank.
. Pre-mix washer fluid concentrates with
water to the manufacturer’s recom-
mended levels before pouring the fluid
into the window washer reservoir tank.
Do not use the window washer reservoir
tank to mix the washer fluid concentrate
and water.
GUID-8579C36F-FFF9-4B84-AE07-383645D32C18.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.
CAUTION
When the battery cable is removed from the
battery terminal, do not close either of front
doors. The automatic window adjusting
function 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
terminal. 5. Securely close the hood.
To connect the negative (−) battery term-
inal, perform the procedure in the follow-
ing 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 term- inal. Then close the hood.
4. Fully open the driver side door window.
5. Close the driver side door and the window.
WARNING
. Do not expose the battery to flames or
electrical sparks. Hydrogen gas gener-
ated 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 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,
always wear suitable eye protection and
remove all jewelry.
. Battery posts, terminals and related
accessories contain lead and lead com-
pounds. Wash hands after handling.
. Keep the battery out of the reach of
children.
DI0137MA
Check the fluid level in each cell (Remove
the battery cover if it is necessary). It
should be between the UPPER LEVEL
*1and LOWER LEVEL*2lines.
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.
SDI1480C
1. Remove the cell plugs*A.
2. Add distilled water up to the UPPER LEVEL
*1line.
If the side of the battery is not clear,
check the distilled water level by
looking directly above the cell; the
condition
*1indicates OK and the
condition
*2needs more to be added.
3. Tighten cell plugs
*A.
Vehicles operated in high temperatures or
under severe conditions require frequent
checks of the battery fluid level.

JUMP STARTINGGUID-06B974E0-9B09-4316-BF6D-083DE94FA734If jump starting is necessary, see“Jump
starting” (P.6-13). If the engine does not
start by jump starting, the battery may
have to be replaced. Contact an INFINITI
retailer.
GUID-ACEB8038-7B64-4F43-B2D3-031914EC39FA
CAUTION
. Do not ground accessories directly to the
battery terminal. Doing so will bypass
the variable voltage control system and
the vehicle battery may not charge
completely.
. Use electrical accessories with the en-
gine running to avoid discharging the
vehicle battery.
The variable voltage control system mea-
sures the amount of electrical discharge
from the battery and controls voltage
generated by the generator.

REPLACING SPARK PLUGSGUID-1EB23356-F5F5-4C2A-851B-89F31CA66D80If replacement is required, see an INFINITI
retailer for servicing.
Iridium-tipped spark plugsGUID-DDA1D9CF-9C6B-4DD6-B89F-D4A52E0AB799It 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 main-
tenance schedule in “INFINITI Service and
Maintenance Guide”, but do not reuse
them by cleaning or regapping.
SPARK PLUGS

Always replace spark plugs with recom-
mended or equivalent ones.

Remove the retainers*1as illustrated and
pull out the filter element
*2.
The filter element should not be cleaned
and reused. Replace it according to the
maintenance intervals. See “INFINITI Ser-
vice and Maintenance Guide” for mainte-
nance 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 is not there, and
the engine backfires, you could be
burned. Do not drive with the air cleaner
removed, and be careful when working
on the engine with the air cleaner
removed.
. 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.

CLEANINGGUID-724353EB-B235-4CC1-A539-18CF071AE36CIf 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 wind-
shield.
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 blade with clear
water. If your windshield 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.
SDI2048
REPLACINGGUID-962249BF-3638-454C-92C6-570D0AE958C2Replace the wiper blades if they are worn.
1.Lift the wiper arm away from the
windshield.
2. Push the release tab
*A, and then
move the wiper blade down the wiper
arm
*1while 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 da-
maged from wind pressure.

SELF-ADJUSTING BRAKESGUID-B60773EA-835E-45EF-8459-943C453A3E2FYour vehicle is equipped with self-adjust-
ing 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 WARNINGGUID-3EBC0D64-F1B6-4853-8B16-7707AECD26FAThe disc brake pads have audible wear
warnings. 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 warning sound is heard.
Under some driving or climate conditions, occasional 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 Service and Maintenance Guide”.
