STEERING
Electric power steering (3.7L, 5.0L and 3.5L EcoBoost™ engines)
WARNING: The electric power steering system has diagnostic
checks that continuously monitor the system to ensure proper
operation. When a system error is detected the following message
Service Power Steering, Service Power Steering Now or Power Steering
Assist Fault may appear in the information display.
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.
If your vehicle loses electrical power while you are driving (or if the 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 permanent damage. Typical
steering and driving maneuvers will allow the system to cool and steering
assist will return to normal.
