ignition INFINITI EX 2011 Owners Manual

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 retainers
1as 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.

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.

PASSENGER 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 fuse box lid.
3. Remove the fuse with the fuse puller
A. 4. If the fuse is open, replace it with a new
fuse.
5. If a new fuse also opens, have the electri- cal system checked and repaired by an
INFINITI retailer. Spare fuses are stored in
the fuse box.
Extended storage switch (if equipped)
To reduce battery drain, the extended storage
switch comes from the factory switched off.
Prior to delivery of your vehicle, the switch is
pushed in (switched on) and should always
remain on.
If any electrical equipment does not operate,
remove the extended storage switch and check
for an open fuse.

Maintenance and do-it-yourself8-21

NOTE:
If the extended storage switch malfunctions, or
if the fuse is open, it is not necessary to replace
the switch. In this case, remove the extended
storage switch and replace it with a new fuse of
the same rating.
How to remove the extended storage switch:
1. To remove the extended storage switch,be sure the ignition switch is in the “OFF”
or “LOCK” position.
2. Be sure the headlight switch is in the “OFF” position.
3. Remove the fuse box cover.
4. Pinch the locking tabs
1found on each
side of the storage switch.
5. Pull the storage switch straight out from the fuse box
2.
Replace the battery as follows:1. Release the lock knob at the back of theIntelligent Key and remove the mechanical
key.
2. Insert a flat-blade screwdriver
A
wrapped with a cloth into the slitBof
the corner and twist it to separate the
upper part from the lower part. 3. Replace the battery with a new one.
Recommended battery: CR2032 or equiva-
lent.
● Do not touch the internal circuit and electric
terminals as it could cause a malfunction.
● Hold the battery by the edges. Holding the
battery across the contact points will seri-
ously deplete the storage capacity.
● Make sure that the + side faces the bottom
of the case.
4. Align the tips of the upper and lower parts, and then push them together until
it is securely closed.
5. Push the buttons two or three times to check its operation.

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.

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.
