Maintaining current speed

Push, arrow 1, or pull, arrow 2, the lever to the resistance point.

The car's current speed is stored and maintained.

It is displayed on the speedometer and briefly in the instrument cluster.

On uphill gradients, it may prove impossible to maintain the set speed if current engine power output is insufficient. If the engine braking effect is insufficient on downhill slopes, the system will brake the vehicle slightly.
