Cruise control accelerates and brakes the vehicle automatically in order to maintain a previously stored speed.
If you accelerate to overtake, for example, the stored speed is not deleted. If you remove your foot from the accelerator pedal after overtaking, cruise control will resume speed regulation back to the stored speed.
You can operate cruise control with the cruise control lever.
If you fail to adapt your driving style, cruise control can neither reduce the risk of an accident nor override the laws of physics. It cannot take into account road, weather or traffic conditions. Cruise control is only an aid. You are responsible for the distance to the vehicle in front, for vehicle speed, for braking in good time and for staying in lane.
Cruise control may be unable to maintain the stored speed on uphill gradients. The stored speed is resumed when the gradient evens out.
Change into a lower gear in good time on long and steep downhill gradients. Take particular note of this when driving a laden vehicle. By doing so, you will make use of the braking effect of the engine. This relieves the load on the brake system and prevents the brakes from overheating and wearing too quickly.
In traffic situations which require frequent changes of speed, e.g. in heavy traffic, on winding roads
On slippery roads. Accelerating can cause the drive wheels to lose traction and the vehicle could then skid
When visibility is poor
