The Four-Wheel Active Steer (4WAS)
system is an electronically controlled
four-wheel steering system.
Depending on the vehicle speed and
steering angle, the angles of the front and
rear wheels are adjusted by the 4WAS
system to help improve driving perfor-
mance.
If a malfunction occurs in the system, the
4WAS function will stop but the ordinary
two-wheel steering system will operate
normally. The “4WAS” warning light will
illuminate. If the light illuminates while
you are driving, contact an INFINITI dealer
for repair.
The steering wheel may be slightly turned
even when driving on a straight road due
to a protection mechanism for the 4WAS
system. This is not a malfunction. The
steering wheel will return to the normal
position after the protection mechanism
deactivates.
The protection mechanism activates
under the following conditions:
O
The steering wheel is operated forcibly
when it is hard to operate or the tires
are blocked by obstacles.
O
The steering wheel is continuously op-
erated when the vehicle is parked or
being driven at extremely low speed.
O
The steering wheel is forcibly turned
beyond its operation limits.
O
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 or glycerin to it through the
key hole. If the lock becomes frozen, heat
the key before inserting it into the key
hole.
ANTIFREEZE
In the winter when it is anticipated that
the temperature will drop below 32°F
(0°C), 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 by
opening the drain plug located under the
FOUR-WHEEL ACTIVE STEER (4WAS)
SYSTEM (if so equipped)
