Porsche Hill Control (PHC)
Porsche Hill Control (PHC) is an assistance system that helps the driver when driving slowly downhill, e.g. on steep slopes or on wintry mountain roads, both when driving forward and reversing.
The system limits the speed through targeted braking at all four wheels. ABS remains active to prevent the wheels from locking.
Reduced braking effect
A with all brakes, the braking effect is impaired on slippery surfaces (e.g. on icy roads or loose surfaces), which can lead to accidents.
Using Porsche Hill Control (PHC)
Porsche Hill Control can only be used if the following prerequisites have been met:
Switching on PHC
The gray PHC symbol on the multifunction display indicates readiness.
PHC control active/desired speed
The set speed is displayed in orange under the PHC symbol, which has now turned white.
The active system switches back to operational readiness if the gradient is less than approx. 6 %.
Switching off PHC
The new desired speed is stored when you release the brake or accelerator pedal and set the desired speed using the control stalk for cruise control or adaptive cruise control.
