STEERING
3.5L EcoBoost™ engine (if equipped): Your vehicle is equipped with
an Electric Power Steering (EPS) 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.
The EPS system has diagnostic checks that continuously monitor the
EPS 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
display in the message center, refer to the Message center in the
Instrument Cluster chapter for more information.
