Should you ever find yourself in a critical situation, the intelligent electronics in the SLK will be there to help. If the car is at risk of skidding, the Electronic Stability Program ESP® can brake one or more wheels in a targeted manner as required, helping the driver to stabilise the vehicle again. If necessary the engine power is also reduced as appropriate. The electronic Brake Assist system can recognise emergency braking by the speed with which you apply the brake and instantly builds up the maximum braking force.

The SLK is available as an option with bi-xenon headlamps equipped with headlamp cleaning system, dynamic headlamp range adjustment and cornering light function. The cornering light function integral to the fog lamps is also automatically activated on the appropriate side at a speed of up to 40 km/h when turning or when driving around narrow corners, providing better illumination of the road.
