STEERING
Electric Power Steering
WARNINGS
The electric power steering system
has diagnostic checks that
continuously monitor the system. If
a fault is detected, a message displays in
the information display. Stop your vehicle
as soon as it is safe to do so. Switch the
ignition off. After at least 10 seconds,
switch the ignition on and watch the
information display for a steering system
warning message. If a steering system
warning message returns, have the system
checked by an authorized dealer.
If the system detects an error, you
may not feel a difference in the
steering, however a serious condition
may exist. Obtain immediate service from
an authorized dealer, failure to do so may
result in loss of steering control.
Your vehicle has an electric power steering
system. There is no fluid reservoir. No
maintenance is required.
If your vehicle loses electrical power while
you are driving, electric power steering
assistance is lost. The steering system still
operates and you can steer your vehicle
manually. Manually steering your vehicle
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
•
Uneven tire wear.
•
Loose or worn suspension
components.
•
Loose or worn steering components.
•
Improper vehicle alignment.
Note:
A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Adaptive Learning
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Additionally, whenever
the battery is disconnected or a new
battery installed, you must drive your
vehicle a short distance before the system
relearns the strategy and reactivates all
systems.
