4 WHEEL ACTIVE STEER (4WAS) SYSTEM (if
so equipped)
The 4 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 performance.
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 retailer 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:
. The steering wheel is operated forcibly
when it is hard to operate or the tires
are blocked by obstacles.
. The steering wheel is continuously
operated when the vehicle is parked
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 techniques.
Ultimately the responsibility for
safety of self and others rests in the hands
of the driver. Therefore only through attentive
and careful driving methods can the
4WAS system be fully appreciated and
safety optimized.
COLD WEATHER DRIVING
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 information,
see “Engine cooling system” in the
“8. Maintenance and do-it-yourself” section.
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.
