The system does not operate if the vehicle speed is below 15 mph when in imperial units or 20 km/h when in metric units. A tone sounds and adaptive braking releases if the vehicle speed falls below 15 mph when in imperial units or 20 km/h when in metric units.
Automatic cancellation can also occur when:
- The tires lose traction.
- You apply the parking brake.
Note:
If the engine speed drops too low, the instrument cluster display advises you to shift to a lower gear.
The system could deactivate or prevent activating when requested if:
- The vehicle has a blocked sensor.
- The brake temperature is too high.
- There is a failure in the system.
