2018 Ford F-350 Owners Manual - Stability Control

Stability Control

Vehicle modifications involving braking system, aftermarket roof racks, suspension, steering system,

tire construction and wheel and tire size may change the handling characteristics of your vehicle and may adversely affect the performance of the electronic stability control system. In addition, installing any stereo loudspeakers may interfere with and adversely affect the electronic stability control system. Install any aftermarket stereo loudspeaker as far as possible from the front center console, the tunnel, and the front seats in order to minimize the risk of interfering with the electronic stability control sensors. Reducing the effectiveness of the electronic stability control system could lead to an increased risk of loss of vehicle control, vehicle rollover, personal injury and death.

Remember that even advanced technology cannot defy the laws of physics. It’s always possible to lose

control of a vehicle due to inappropriate driver input for the conditions. Aggressive driving on any road condition can cause you to lose control of your vehicle increasing the risk of personal injury or property damage. Activation of the electronic stability control system is an indication that at least some of the tires have exceeded their ability to grip the road; this could reduce the operator’s ability to control the vehicle potentially resulting in a loss of vehicle control, vehicle rollover, personal injury and death. If your electronic stability control system activates, SLOW DOWN.

The system automatically turns on each time you switch the ignition on.

If a fault occurs in either the stability control or the traction control system, you may experience the following conditions:

The stability and traction control light illuminates steadily.

The stability control and traction control systems do not enhance your vehicle's ability to maintain traction of the wheels.

The Adaptive Steering system (if equipped) automatically changes the steering function to a fixed steering ratio. See Steering (page 259).

If a driving condition activates either the stability control or the traction control system you may experience the following conditions:

The stability and traction control light flashes.

Your vehicle slows down.

Reduced engine power.

A vibration in the brake pedal.

The brake pedal is stiffer than usual.

If the driving condition is severe and your foot is not on the brake, the brake pedal may move as the system applies higher brake force.

The stability control system has several features built into it to help you maintain control of your vehicle:

The system enhances your vehicle’s ability to prevent skids or lateral slides by applying brakes to one or more of the wheels individually and, if necessary, reducing engine power.

230

The system enhances your vehicle’s ability to prevent rollovers by detecting your vehicle’s roll motion and the rate at which it changes by applying the brakes to one or more wheels individually.

The system enhances your vehicle’s ability to maintain traction of the wheels by detecting and controlling wheel spin. See Using Traction Control (page 229).

The system automatically turns on each time you switch the ignition on.

The electronic stability control and roll stability control portions of the system can be turned off.

When you shift the transmission into reverse R, the systems disable.

Use the traction and stability control switch on the instrument panel to switch the systems off

or on.

You can switch the traction control portion of the system off independently.

If you cannot turn the systems off, see the MyKey chapter for more information.
