ELECTRIC POWER STEERING PRECAUTIONS



WARNING:  The electric power steering system has diagnostic checks that continuously monitor the system. If a fault is detected, a message displays in the information display. Stop your vehicle as soon as it is safe to do so. Switch the vehicle off. After at least 10 seconds, switch the vehicle on and watch the information display for a steering system warning message. If a steering system warning message returns, have the system checked as soon as possible.    WARNING:  If the system detects an error, you may not feel a difference in the steering, however a serious condition may exist. Have your vehicle checked as soon as possible. Failure to do so may result in loss of steering control.

Adapt your speed and driving behavior according to reduced steering assist.

Extreme continuous steering may increase the effort to steer. This occurs to prevent internal overheating and damage to the steering system. If this occurs, you will not lose the ability to steer your vehicle manually nor will it cause damage to the system. Normal steering and driving allows the system to cool down and steering assist returns to normal.

Note:   There is no fluid reservoir to check or fill.

ELECTRIC POWER STEERING ADAPTIVE STEERING (IF EQUIPPED)

The adaptive steering system changes the steering ratio with changes to vehicle speed, optimizing the steering response in all conditions. The system also changes when you switch on the transmission tow/haul feature. When you select the tow/haul button, the adaptive steering system reduces vehicle sensitivity to steering inputs at higher vehicle speeds, while maintaining the ease of parking and maneuverability at low speeds.

Note:   The adaptive steering system continuously monitors for faults. If the system detects a fault, a message appears in the information display. If a red warning message displays, stop your vehicle as soon as it is safe to do so. The message could clear if the fault is no longer present. If an adaptive steering system warning message appears each time you start your vehicle, have the system checked as soon as possible.

Note:   The system has a locking device. It remains mechanically locked at a fixed steering ratio with the lock engaged. You may notice a click when you turn your vehicle on or off.

Note:   If your vehicle loses electrical power or detects a fault when you are driving, the system shuts down and you retain a normal steering function with a fixed steering ratio. During this time, it is possible that the steering wheel could not be straight when the vehicle is driving straight ahead. In addition, you could notice that the steering wheel angle required to steer your vehicle could be different.

Note:   During parking maneuvers, the adaptive steering system balances the driver workload for various steering wheel inputs and vehicle loading conditions. Under extreme operating conditions the system locking device could engage. This strategy prevents overheating and permanent damage to the adaptive steering system. Typical steering and driving maneuvers allow the system to cool and return to normal operation.

ADAPTIVE LEARNING

Adaptive learning helps correct road irregularities and improves overall handling and steering. It communicates with the brake system to help operate advanced stability control and crash avoidance systems. Additionally, whenever you disconnect the battery or install a new battery, you must drive your vehicle a short distance before the system relearns the strategy and reactivates all systems.

STEERING – WARNING INDICATORS

  The electric power steering system indicator illuminates if the system detects a fault during the continuous diagnostic checks.

Note:   If a red warning message displays, stop your vehicle as soon as it is safe to do so.
