2011 INFINITI M engine

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.
1. Remove the cell plugsA.
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 conditions
2needs more to be
added.
3. Tighten cell plugsA.
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.

2. Alternator
3. Crankshaft pulley
4. Air conditioner compressor
5. Drive belt auto-tensioner
WARNING
Be sure the ignition switch is in the OFF or LOCK
position before servicing drive belts. The en-
gine could rotate unexpectedly.
1. Visually inspect each belt for signs of unusual wear, cuts, fraying or looseness.
If the belt is in poor condition or loose,
have it replaced or adjusted by an INFINITI
retailer.
2. Have the belts checked regularly for con- dition and tension in accordance with the
maintenance schedule in your “INFINITI
Service and Maintenance Guide”.VK56VD engine

WARNING
Be sure the engine and the 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.
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 retainers1as 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.
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.
Before replacing the wiper blades, the wiper
should be in the fully up position to avoid
scratching the engine hood or damaging the
wiper arm. To pull up the wiper arm, see
“WINDSHIELD WIPER AND WASHER SWITCH” in
the “2. Instruments and controls” section.
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. 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.

ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower amperage
rating than that specified on the fuse box cover.
This could damage the electrical system or
cause a fire.
If any electrical equipment does not operate,
check for an open fuse.
1. Be sure the ignition switch is pushed to the OFF or LOCK position and the head-
light switch is turned to OFF.
2. Open the engine hood and remove the cover on the battery and the fuse/fusible
link holder.
3. Remove the fuse/fusible link holder cover.
4. Remove the fuse with the fuse puller. 5. If the fuse is open
A, replace it with a
new fuse
B. Spare fuses are stored in the
passenger compartment fuse box.
6. If a new fuse also opens, have the elec- trical system checked and repaired by an
INFINITI retailer.
The holder1also contains the fuses. For
checking and/or replacing, see an INFINITI re-
tailer.
Fusible links
If any electrical equipment does not operate
and fuses are in good condition, check the
fusible links. If any of these fusible links are
melted, replace only with genuine INFINITI
parts.
