2011 INFINITI EX check 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 condition
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.

8-14Maintenance and do-it-yourself

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.
1. Power steering fluid pump
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”.

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. Be sure the ignition switch is pushed to the OFF
or LOCK position and the headlight switch is
turned to OFF.
1. Open the engine hood and remove the
battery cover.
2. Remove the fuse/fusible link holder cover.
3. Remove the fuse with the fuse puller.
4. If the fuse is open
A, replace it with a
new fuse
B. Spare fuses are stored in the
passenger compartment fuse box.
5. If a new fuse also opens, have the electri- cal system checked and repaired by an
INFINITI retailer.
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.

E-85 fuel
E-85 fuel is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. E-85 can
only be used in a Flexible Fuel Vehicle (FFV). Do
not use E-85 fuel in your vehicle. U.S. govern-
ment regulations require fuel ethanol dispens-
ing pumps to be identified by a small, square,
orange and black label with the common abbre-
viation or the appropriate percentage for that
region.
Aftermarket fuel additives
INFINITI does not recommend the use of any
aftermarket fuel additives (Example: fuel injec-
tor cleaner, octane booster, intake valve de-
posit removers, etc.) which are sold commer-
cially. Many of these additives intended for
gum, varnish or deposit removal may contain
active solvent or similar ingredients that can be
harmful to the fuel system and engine.
Octane rating tips
Using unleaded gasoline with an octane rating
lower than recommended above can cause per-
sistent, heavy spark knock. (Spark knock is a
metallic rapping noise.) If severe, this can lead
to engine damage. If you detect a persistent
heavy spark knock even when using gasoline of
the stated octane rating, or if you hear steady
spark knock while holding a steady speed onlevel roads, have an INFINITI retailer correct the
condition. Failure to correct the condition is mis-
use of the vehicle, for which INFINITI is not re-
sponsible.
Incorrect ignition timing will result in knocking,
after-run or overheating. This in turn may cause
excessive fuel consumption or damage to the
engine. If any of the above symptoms are
encountered, have your vehicle checked at an
INFINITI retailer or other competent service fa-
cility.
However, now and then you may notice light
spark knock for a short time while accelerating
or driving up hills. This is no cause for concern,
because you get the greatest fuel benefit when
there is light spark knock for a short time under
heavy engine load.
CAUTION
●
Your vehicle is not designed to run on E-85
fuel. Using E-85 fuel in a vehicle not specifi-
cally designed for E-85 fuel can damage fuel
system components and is not covered by
the INFINITI new vehicle limited warranty.
● E-85 is a mixture of approximately 85% fuel
ethanol and 15% unleaded gasoline. ●
U.S. government regulations require ethanol
dispensing pumps to be identified by a
small, square, orange and black label with
the common abbreviation or the appropriate
percentage for that region.
9-4Technical and consumer information

Additional information concerning motor
vehicle safety may be obtained from
Transport Canada’s Road Safety Infor-
mation Centre at 1-800-333-0371 or on-
line at www.tc.gc.ca/roadsafety (English
speakers) or
www.tc.gc.ca/securiteroutiere (French
speakers).
To notify INFINITI of any safety concerns
please contact our Consumer Informa-
tion Centre toll free at 1-800-361-4792.A vehicle equipped with All-Wheel Drive (AWD)
should never be tested using a two wheel
dynamometer (such as the dynamometers used
by some states for emissions testing), or similar
equipment. Make sure you inform test facility
personnel that your vehicle is equipped with
AWD before it is placed on a dynamometer.
Using the wrong test equipment may result in
transmission damage or unexpected vehicle
movement which could result in serious vehicle
damage or personal injury.
Due to legal requirements in some states/ areas
or provinces, your vehicle may be required to be
in what is called the “ready condition” for an
Inspection/Maintenance (I/M) test of the emis-
sion control system.
The vehicle is set to the “ready condition” when
it is driven through certain driving patterns.
Usually, the “ready condition” can be obtained
by ordinary usage of the vehicle.
If a powertrain system component is repaired or
the battery is disconnected, the vehicle may be
reset to a “not ready condition”. Before taking
the I/M test, check the vehicle’s
inspection/maintenance test readiness condi-
tion. Place the ignition switch in the ON position
without starting the engine. If the Malfunction
Indicator Light (MIL) comes on steady for 20
seconds and then blinks for 10 seconds, the I/Mtest condition is “not ready”. If the MIL does not
blink after 20 seconds, the I/M test condition is
“ready”.
Contact a INFINITI retailer to set the “ready
condition” or to prepare the vehicle for testing.
