key battery INFINITI FX 2012 Owner's Manual

The Rear Active Steer system is an electro-
nically controlled four-wheel steering sys-
tem.
The angle of the rear wheels are adjusted
by the Rear Active Steer system, depending
on the vehicle speed and steering angle.
The rear wheels are designed to turn
momentarily in the opposite direction and
then change to the same direction as the
front wheels.
At low speeds, the rear wheels will not turn
and the system functions as a two-wheel
steering system.
If a malfunction occurs in the system, the
Rear Active Steer function will stop but the
ordinary two-wheel steering system will
operate normally. The“RAS”warning light
will illuminate. If the light illuminates while
driving, contact an INFINITI retailer for
repair.
WARNING
The Rear Active Steer system, although a
sophisticated device, cannot prevent acci-
dents resulting from careless or dangerous
driving techniques. Ultimately the responsi-
bility for safety of self and others rests in
the hands of the driver. Therefore only through attentive and careful driving meth-
ods can the Rear Active Steer system be
fully appreciated and safety assured.
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 328F
(08C), check antifreeze to assure proper
winter protection. For additional informa-
tion, see “Engine cooling system” (P.8-9).
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”
(P.8-17).
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” (P.8-9).

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” (P.7-2).
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
.
Park the vehicle on a level surface, apply
the parking brake securely and block the
wheels to prevent the vehicle from
moving. Move the selector lever to P
(Park).
. Be sure the ignition switch is in the OFF
or LOCK position when performing any
parts replacement or repairs.
. Never connect or disconnect the battery
or any transistorized component while
the ignition switch is in the ON position.
. Never leave the engine or automatic
transmission related component har-
nesses disconnected while the ignition
switch is in the ON position.
. If you must work with the engine
running, keep your hands, clothing, hair
and tools away from moving fans, belts
and any other moving parts. .
It is advisable to secure or remove any
loose clothing and remove any jewelry,
such as rings, watches, etc. before
working on your vehicle.
. Always wear eye protection whenever
you work on your vehicle.
. If you must run the engine in an
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.
. On gasoline engine models, the fuel
filter or fuel lines should be serviced by
an INFINITI retailer because the fuel lines
