2012 INFINITI M key battery

If the battery of the vehicle is discharged,
the push-button ignition switch cannot be
turned from the LOCK position.
Some indicators and warnings for opera-
tion are displayed on the dot matrix liquid
crystal display between the speedometer
and tachometer. (See“Dot matrix liquid
crystal display ”in the “2. Instruments and
controls ”section.)
The ignition lock is designed so that the
ignition switch position cannot be switched
to LOCK until the selector lever is moved to
the P (Park) position.
When the ignition switch cannot be pushed
toward the LOCK position, proceed as
follows:
1. Move the selector lever into the P (Park) position.
2. Push the ignition switch to the OFF position. The ignition switch position
indicator will not illuminate.
3. Open the door. The ignition switch will change to the LOCK position.
The selector lever can be moved from the P
(Park) position if the ignition switch is in
the ON position and the brake pedal is
depressed.STEERING LOCK (if so equipped)
In order for the steering wheel to be
locked, it must be turned about 1/8 of a
right or left turn from the straight up
position.
To lock the steering wheel, push the
ignition switch to the OFF position. To
unlock the steering wheel, push the
ignition switch. If the steering lock release
malfunction indicator appears on the dot
matrix liquid crystal display, push the
push-button ignition switch again while
lightly turning the steering wheel right
and left. (See “Dot matrix liquid crystal
display ”in the “2. Instruments and con-
trols ”section.)

POSITIONS
LOCK (Normal parking position)
The ignition switch can only be locked in
this position.
The ignition switch will be unlocked when
it is pushed to the ACC position while
carrying the Intelligent Key.
ACC (Accessories)
This position activates electrical acces-
sories such as the radio, when the engine
is not running.
ON (Normal operating position)
This position turns on the ignition system
and electrical accessories.
OFF
The engine can be turned off in this
position.
The ignition lock is designed so that the
ignition switch cannot be switched to the
LOCK position until the selector lever is
moved to the P (Park) position.
CAUTION
Do not leave the vehicle with the push-
button ignition switch in ACC or ON posi-
tions when the engine is not running for an
extended period. This can discharge the
battery.

INTELLIGENT KEY BATTERY DIS-
CHARGE
If the battery of the Intelligent Key is
discharged, or environmental conditions
interfere with the Intelligent Key operation,
start the engine according to the following
procedure:
1. Move the selector lever to the P (Park)
position.
2. Firmly apply the foot brake.
3. Touch the ignition switch with the Intelligent Key as illustrated. (A chime
will sound.) 4. Push the ignition switch while depres-
sing the brake pedal within 10 seconds
after the chime sounds. The engine will
start.
After step 3 is performed, when the
ignition switch is pushed without depres-
sing the brake pedal, the ignition switch
position will change to ACC.
NOTE:
. When the ignition switch is pushed to
the ACC or ON position or the engine is
started by the above procedures, the
Intelligent Key battery discharge indi-
cator appears on the dot matrix liquid
crystal display even if the Intelligent
Key is inside the vehicle. This is not a
malfunction. To turn off the Intelligent
Key battery discharge indicator, touch
the ignition switch with the Intelligent
Key again.
. If the Intelligent Key battery discharge
indicator appears, replace the battery
as soon as possible. (See “Intelligent
Key battery replacement” in the“8.
Maintenance and do-it-yourself ”sec-
tion.)

or being driven at extremely low speed.
. The steering wheel is forcibly turned
beyond its operation limits.
. The battery voltage is reduced.
Repeated steering maneuvers that may
activate the protection mechanism will
damage the 4WAS system.
WARNING
The 4WAS system, although a sophisticated
device, cannot prevent accidents resulting
from careless or dangerous driving tech-
niques. Ultimately the responsibility for
safety of self and others rests in the hands
of the driver. Therefore only through atten-
tive and careful driving methods can the
4WAS system be fully appreciated and
safety optimized.
FREEING A FROZEN DOOR LOCK
To prevent a door lock from freezing, apply
deicer through the key hole. If the lock
becomes frozen, heat the key before
inserting it into the key hole or use the
Intelligent Key system.
ANTIFREEZE
In the winter when it is anticipated that the
outside temperature will drop below 32 8F
(0 8C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” in the
“ 8. Maintenance and do-it-yourself ”sec-
tion.
BATTERY
If the battery is not fully charged during
extremely cold weather conditions, the
battery fluid may freeze and damage the
battery. To maintain maximum efficiency,
the battery should be checked regularly.
For additional information, see “Battery ”in
the “8. Maintenance and do-it-yourself ”
section.
DRAINING OF COOLANT WATER
If the vehicle is to be left outside without
antifreeze, drain the cooling system, in-
cluding the engine block. Refill before
operating the vehicle. For details, see
“ Engine cooling system” in the“8. Main-
tenance and do-it-yourself ”section.
TIRE EQUIPMENT
SUMMER tires have a tread designed to
provide superior performance on dry pave-
ment. However, the performance of these
tires will be substantially reduced in snowy
and icy conditions. If you operate your
vehicle on snowy or icy roads, INFINITI
recommends the use of MUD & SNOW or
ALL SEASON tires on all four wheels.
Consult an INFINITI retailer for the tire
type, size, speed rating and availability
information.
For additional traction on icy roads,
studded tires may be used. However, some
U.S. states and Canadian provinces prohi-
bit their use. Check local, state and
provincial laws before installing studded
tires.

vehicle has been parked for a while. Water
dripping from the air conditioner after use
is normal. If you should notice any leaks or
if gasoline fumes are evident, check for the
cause and have it corrected immediately.
Power steering fluid level* and lines:
Check the level when the fluid is cold,
with the engine off. Check the lines for
proper attachment, leaks, cracks, etc.
Radiator and hoses:Check the front of the
radiator and clean off any dirt, insects,
leaves, etc., that may have accumulated.
Make sure the hoses have no cracks,
deformation, rot or loose connections.
Underbody: The underbody is frequently
exposed to corrosive substances such as
those used on icy roads or to control dust.
It is very important to remove these
substances, otherwise rust will form on
the floor pan, frame, fuel lines and around
the exhaust system. At the end of winter,
the underbody should be thoroughly
flushed with plain water, being careful to
clean those areas where mud and dirt may
accumulate. For additional information,
see “Cleaning exterior ”in the “7. Appear-
ance and care ”section.
Windshield washer fluid*: Check that there
is adequate fluid in the reservoir. When performing any inspection or main-
tenance work on your vehicle, always take
care to prevent serious accidental injury to
yourself or damage to the vehicle. The
following are general precautions which
should be closely observed.
WARNING

enclosed space such as a garage, be
sure there is proper ventilation for
exhaust gases to escape.
. Never get under the vehicle while it is
supported only by a jack. If it is
necessary to work under the vehicle,
support it with safety stands.
. Keep smoking materials, flame and
sparks away from fuel tank and the
battery.
. Your vehicle is equipped with an auto-
matic engine cooling fan. It may come on
at any time without warning, even if the
ignition key is in the OFF position and
the engine is not running. To avoid
injury, always disconnect the negative
battery cable before working near the
fan.
. The fuel filter or fuel lines should be
serviced by an INFINITI retailer because
the fuel lines are under high pressure
