Steering  - Driving - Lincoln MKS Owners Manual - Lincoln MKS

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.

WARNING: The EPS system has diagnostics checks that continuously monitor the EPS system to ensure proper operation of the electronic system. When an electronic error is detected, the message POWER STEERING ASSIST FAULT will be displayed in the message center. 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 message center 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 the message SERVICE POWER STEERING is displayed in the message center, the EPS system has detected a problem with the system function. On the next key cycle the message 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.

3.7L V6 Duratec engine: Your vehicle is equipped with a hydraulic steering system.

To help prevent damage to the power steering system, never hold the steering wheel at its furthest turning points (until it stops) for more than a few seconds when the engine is running. If the power steering system breaks down (or if the engine is turned off), you can steer the vehicle manually, but it takes more effort.

• Do not operate the vehicle with a low power steering pump fluid level (below the MIN mark on the reservoir).
• Some noise is normal during operation. If excessive, check for low power steering pump fluid level before seeking service by your authorized dealer.
• Heavy or uneven steering efforts may be caused by low power steering pump fluid level. Check for low power steering pump fluid level before seeking service by your authorized dealer.
• Do not fill the power steering pump reservoir above the MAX mark on the reservoir, as this may result in leaks from the reservoir.

If the steering wanders or pulls equipped with either EPS or hydraulic steering system, check for:

• an improperly inflated tire
• uneven tire wear
• loose or worn suspension components
• loose or worn steering components
• improper vehicle alignment

A high crown in the road or high crosswinds may also make the steering seem to wander/pull.

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.
