During some operating conditions, the active steering
might deactivate to protect the system from damage. You
might notice that the center position of the steering wheel
is changed. Unless there is a SERVICE STEERING SYS
message, the system will return to normal operation as
soon as the condition ceases, usually within a very short
period of time.
At low speeds, the active steering system requires less
movement of the steering wheel to change vehicle
direction than the normal power steering system.
Adjust your driving accordingly.
When certain steering faults are present, the active
steering deactivates and vehicle speed might be limited.
The SERVICE STEERING SYS and SPEED LIMITED
TO XXX messages will be displayed. See DIC Warnings
and Messages on page 3-79. The normal power steering
system is still operational. You might notice that the
center position of the steering wheel is changed and that
more steering effort at low speeds and less steering effort
at high speeds is required. You can continue to drive your
vehicle with normal power steering but you should have
your dealer/retailer inspect the steering system as soon
as possible in order to have the problem corrected and
the steering wheel position centered.
When stability control activates, the system
automatically adjusts the front road wheel steering
angle, modifies the suspension stiffness, and selectively
applies braking pressure at any one of the vehicle’s
brakes to help maintain directional control of the vehicle.
Adjustments to the steering will not be felt in the
steering wheel. See Enhanced StabiliTrak
®
on page 4-6.
It is recommended that the battery not be disconnected
when the steering wheel is turned from the center
position. If this occurs, the center position of the steering
wheel could be temporarily changed a small amount.
You can continue to operate your vehicle and, after
a short time, the center position of the steering wheel
will return to normal.
Steering Tips
It is important to take curves at a reasonable speed.
Traction in a curve depends on the condition of the tires
and the road surface, the angle at which the curve is
banked, and your speed. While in a curve, speed is the
one factor you can control.
If you need to reduce speed, do it before you enter the
curve, while the front wheels are straight ahead.
Try to adjust the speed so you can drive through the
curve. Maintain a reasonable, steady speed. Wait
to accelerate until you are out of the curve, and then
accelerate gently into the straightaway.
