WARNING: The electric power steering system has diagnostics
checks that continuously monitor the system to ensure proper
operation of the electronic system. When an electronic error is detected,
Power Steering Assist Fault will be displayed in the information display. If
this happens, stop the vehicle in a safe place, and turn off the engine.
After at least 10 seconds, reset the system by restarting the engine, and
watch the information display for Power Steering Assist Fault. If the
message returns, or returns while driving, take the vehicle to your dealer
to have it checked. With the message displayed, the steering assist is
turned off, making the vehicle harder to steer.
WARNING: If Service Power Steering is displayed in the information
display, a problem with the system function has been detected. On
the next key cycle Service Power Steering Now will be displayed and
steering assist will be removed until the steering system is serviced. Have
your vehicle taken to the nearest dealer as soon as possible.
WARNING: Obtain immediate service if a system error is
detected. You may not notice any difference in the feel of your
steering, but a serious condition may exist. Failure to do so may result
in loss of steering control.
Your vehicle is equipped with an electric power-assisted steering system.
There is no fluid reservoir to check or fill.

ignition is turned off), you can steer the vehicle manually, but it takes
more effort. Extreme continuous steering may increase the effort it takes
for you to steer. This occurs to prevent internal overheating and
permanent damage to your steering system. If this should occur, you will
neither lose the ability to steer the vehicle manually nor will it cause
