2011 INFINITI EX battery

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”.

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

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.

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-

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.
