ADAPTIVE SPEED LIMITER CONTROLS

WARNING

The adaptive speed limiter is a driving aid only. Driving with due care and attention, and in a manner which is safe for the vehicle, its occupants and other road users, remains the driver’s responsibility. The driver should still observe all other road signs, road markings, and situations that are not detected or recognized by the traffic sign recognition system. Driving without due care and attention greatly increases the risk of an accident.

WARNING

In certain conditions, such as a steep downhill gradient, the vehicle's speed may exceed the set speed limit. Driver intervention may be required as engine braking is unable to maintain or reduce the vehicle's speed. Driving at speeds above the set speed limit may infringe on local laws.

NOTES

The adaptive speed limiter is not available when cruise control is in operation.

The adaptive speed limiter works in conjunction with the traffic sign recognition and navigation systems to restrict the maximum vehicle speed. The maximum speed is set, based on the information received from both of these systems. If the system cannot determine a valid maximum speed, the adaptive speed limiter is deactivated and the speed limiter is activated. See SPEED LIMITER CONTROLS.

To switch the adaptive speed limiter on, press the LIM button on the steering wheel. Depending on vehicle status, the instrument panel displays either the speed limiter or the adaptive speed limiter information lamp. If speed limiter is displayed, press and hold the CAN button on the steering wheel. The speed limiter information lamp is replaced with the adaptive speed limiter information lamp to confirm that adaptive speed limiter has been selected. See ADAPTIVE SPEED LIMITER (AMBER).

The adaptive speed limiter does not operate until activated. To activate the adaptive speed limiter, press the SET+ button or the RES button on the steering wheel. The instrument panel and Head-Up Display (HUD) display detected speed limits as icons. See HEAD-UP DISPLAY (HUD).

NOTES

The adaptive speed limiter can also be switched on and off via the Driver Assistance instrument panel menu. If cruise control is in operation, this option is grayed-out in the instrument panel. See INSTRUMENT PANEL MENU.

If the adaptive speed limiter detects a speed limit lower than the current vehicle speed, the system automatically slows the vehicle to meet the speed limit. Pressing the RES button on the steering wheel increases the rate of deceleration.

If the adaptive speed limiter detects a speed limit higher than the current vehicle speed, the system allows the driver to accelerate. The vehicle stops accelerating when the detected speed limit is reached. Pressing the RES button on the steering wheel increases the rate of acceleration.

To suspend adaptive speed limiter operation, press the CAN button on the steering wheel. To resume adaptive speed limiter operation, press the RES button or the SET+ button on the steering wheel.

When the adaptive speed limiter is active, vehicle speed may increase in certain conditions, e.g., when traveling downhill. A warning message displays in the instrument panel if the vehicle’s speed rises by more than 2 mph (3.5 km/h) above the adaptive speed limiter detected speed limit. If the vehicle’s speed rises by more than 5 mph (7 km/h) above the adaptive speed limiter's detected speed limit for 4 seconds, a chime also sounds.

The adaptive speed limiter's detected speed limit can be overridden if rapid acceleration is required. Rapid acceleration is also known as kickdown. See AUTOMATIC TRANSMISSION.

If kickdown is required, the vehicle accelerates past the adaptive speed limiter's detected speed limit. When the vehicle's speed drops below the adaptive speed limiter's detected speed limit, any speed limitations are reapplied.

The adaptive speed limiter's detected speed limit can be adjusted, if required, to control the vehicle’s speed at just above or below the detected speed limit. To adjust the detected speed limit:

  • Press the SET+ button to raise the maximum vehicle speed 1 mph (2 km/h) above the detected speed limit. The maximum increase available is 6 mph (10 km/h) above the detected speed limit. Press and hold the SET+ button to raise the maximum vehicle speed directly to 6 mph (10 km/h) above the detected speed limit.

  • Press the - button to lower the maximum vehicle speed 1 mph (2 km/h) below the detected speed limit. The maximum decrease available is 6 mph (10 km/h) below the detected speed limit. Press and hold the - button to lower the maximum vehicle speed directly to 6 mph (10 km/h) below the detected speed limit.

WARNING

Speed limiters are convenience features only. Speed limiters do not remove the driver’s responsibility to adhere to the legal road speed limit.

NOTES

Any adjustments to the adaptive speed limiter's detected speed limit are lost if the speed limiter is activated, or the vehicle’s ignition is switched off.

If the traffic sign recognition system cannot determine a valid speed limit, it displays - - -. If this occurs, the adaptive speed limiter remains set at the last known valid speed limit. If the traffic sign recognition system is unable to detect a valid speed limit within a short period of time, the adaptive speed limiter is deactivated. If this occurs, the speed limiter is activated.

To override the speed limiter, fully press the accelerator pedal.

Adaptive speed limiter limitations:

The following adaptive speed limiter operating limitations apply:

  • Adaptive speed limiter performance and accuracy is only as good as the information provided to it by the traffic sign recognition system. See TRAFFIC SIGN RECOGNITION.

  • Adaptive speed limiter performance and accuracy is only as good as the information provided to it by the navigation system. Always make sure the system is operating correctly, and has the latest software. See MAP UPDATES.

  • The maximum speed limit recognized by the adaptive speed limiter is 80 mph (130 km/h). For any detected speeds above this figure, the adaptive speed limiter sets an unlimited maximum speed.

  • The minimum speed limit recognized by the adaptive speed limiter is 19 mph (30 km/h). For any detected speeds below this figure, the adaptive speed limiter sets a speed limit of 19 mph (30 km/h). The instrument panel displays the message LIMITER SET SPEED ABOVE SPEED LIMIT.
