The 12-volt battery*Ais located on the
left hand side of the trunk behind an
access panel.
. 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
discharge.
NOTE:
Care should be taken to avoid situations that can lead to potential 12-volt battery
discharge and potential no-start condi-
tions such as:
1.
Installation or extended use of electro-
nic accessories that consume 12-volt
battery power when the engine is not
running (Phone chargers, GPS, DVD
players, etc.)
2. Vehicle is not driven regularly and/or
only driven short distances.
In these cases, the 12-volt battery may
need to be charged to maintain 12-volt
battery health.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, 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. .
The Hybrid vehicle uses a special bat-
tery. If the battery needs to be replaced,
use a battery of the same design. Using
the wrong battery can cause hydrogen
gas to build up in the vehicle, which
could lead to an explosion and personal
injury.
. 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 battery out of the reach of children.

REPLACING SPARK PLUGS
If replacement is required, see an INFINITI
retailer 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 main-
tenance schedule in“INFINITI Service and
Maintenance Guide” , but do not reuse
them by cleaning or regapping. Always replace spark plugs with recom-
mended or equivalent ones.SDI2546

AIR CLEANER

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 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.
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 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.
Worn windshield wiper blades can damage
the windshield and impair driver vision.

washer switch” (P.2-35).
1. Pull the wiper arm.
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.
