—If the engine is not running smoothly or there is an engine fault.
—If the engine is switched off or has stalled.
—When the gearbox is in neutral position .
—When a gear selector position facing down the hill is selected.
CAUTION
If you do not drive off immediately after releasing the brake pedal, the vehicle may roll opposite the direction of travel when moving
off. This can lead to injuries or damage.
● In this case, press the brake pedal immediately or switch on the electronic parking brake.
● If you want to prevent the vehicle rolling opposite the direction of travel when you drive off on an uphill gradient in dense traffic,
press the brake pedal before you drive off.
Downhill speed control helps the rider when travelling downhill.
Function
The dual clutch gearbox DSG® selects the best gear depending on the steepness of the gradient and the current speed. The
position must be engaged for this. The downhill speed control system is not active in Tiptronic mode.
As the downhill speed control can shift down only as far as third gear, it may be necessary to activate the Tiptronic mode when driving
down particularly steep inclines. In order to use the braking effect of the engine and relieve the load on the brakes, shift manually to
second or first gear in Tiptronic mode.
The start/stop system is automatically deactivated as long as downhill speed control is active.
Activating downhill speed control automatically
—If the downhill gradient is greater than approximately 6%.
if the
position is engaged.
—In addition, if Adaptive Cruise Control (ACC) is switched off: if the vehicle speed is less than around 80 km/h (around 50 mph).
the brake is pressed.
—In addition, if Adaptive Cruise Control (ACC) is active: if the stored speed is exceeded.
Deactivating downhill speed control automatically
—If the downhill gradient becomes less steep.
—If the gearbox shifts up because the maximum engine speed of the function has been reached.
—If Adaptive Cruise Control (ACC) is also active: if the stored speed can be maintained.
WARNING
The downhill speed control system is not a substitute for the full attention of the driver and operates only within the limits of the
system. The downhill speed control system cannot detect all driving situations and may not react or may react with a delay or in an
undesired way. If you do not pay due attention, there is a risk of accidents due to unintentional vehicle movements. This can cause
severe or fatal injuries.
● Always pay due attention and do not rely exclusively on the system. The driver is always responsible for all driving tasks.
● Please note that the downhill speed control system cannot always hold the vehicle on an uphill gradient or sufficiently brake the
vehicle on downhill gradients, e.g. on slippery or icy surfaces.
● Always be ready to brake, particularly on slippery or icy surfaces.
● Brake the vehicle manually if the vehicle becomes faster in spite of downhill speed control.
● Ensure that your speed and driving style are always appropriate for the current visibility, weather and road/traffic conditions.
