Visit an INFINITI retailer and seek advice
NOTE
You can obtain information about trickle char-
gers from an INFINITI retailer. The electric power steering system is designed
to reduce the driver effort required to steer the
vehicle.
WARNING
If during operation a fault is detected the fol-
lowing message will be displayed in the ve-
hicle information display along with an audible
warning tone.
[Power Steering Malfunction See Operators
Manual]
In conjunction with this warning, steering as-
sistance will no longer be provided by the sys-
tem.
The effort required to steer the vehicle will
increase. This will be most noticeable at low
speed and when performing a tight turning
maneuver.
Check whether you are able to provide the ex-
tra effort required.
If you are able to steer safely: Carefully drive on
to an INFINITI retailer.

on. It is recommended you contact the nearest
INFINITI retailer for assistance.
ELECTRIC POWER STEERING SYSTEM
5-86Starting and driving

WARNING
•Never rely solely on the Hill Start Assist
(HSA) system to prevent the vehicle from
moving backward on a hill. Always drive
carefully and attentively. Depress the brake
pedal when the vehicle is stopped on a
steep hill. Be especially careful when
stopped on a hill on frozen or muddy roads.
Failure to prevent the vehicle from rolling
backwards may result in a loss of control of
the vehicle and possible serious injury or
death.
•The Hill Start Assist system is not designed
to hold the vehicle at a standstill on a hill.
Depress the brake pedal when the vehicle is
stopped on a steep hill. Failure to do so may
cause the vehicle to roll backwards and may
result in a collision or serious personal in-
jury.
•The Hill Start Assist system may not prevent
the vehicle from rolling backwards on a hill
under all load or road conditions. Always be
prepared to depress the brake pedal to pre-
vent the vehicle from rolling backwards.
Failure to do so may result in a collision or
serious personal injury.
•After a short time, hill start assist will no
longer brake your vehicle and it could rollaway There is a risk of an accident and in-
jury. Therefore, quickly move your foot from
the brake pedal to the accelerator pedal.
Never leave the vehicle when it is held by
hill start assist.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient. It
holds the vehicle for a short time after you have
removed your foot from the brake pedal. This
gives you enough time to move your foot from
the brake pedal to the accelerator pedal and
depress it before the vehicle begins to roll.
Hill start assist is not active if
•You are pulling away on a level road or a
downhill gradient.
•On vehicles with automatic transmission, the
transmission is in position N.
•The electric parking brake is applied.
•VDC is malfunctioning.
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 INFINITI Intelligent Key.
ANTIFREEZE
In the winter when it is anticipated that the
temperature will drop below 32°F (0°C), check
the antifreeze to assure proper winter protec-
tion. For additional information, see Engine
cooling system in the8. Do-it-yourself sec-
tion.
BATTERY
If the battery is not fully charged during ex-
tremely cold weather conditions, the battery
fluid may freeze and damage the battery. To
maintain maximum efficiency, the battery
should be checked regularly. For details, see
Battery in the8. Do-it-yourself section of this
manual.
DRAINING OF ENGINE COOLANT
If the vehicle is to be left outside without
antifreeze, drain the cooling system, including
the engine block. Refill before operating the
vehicle. For details, see Changing engine
