Function of Adaptive Brake Lights
Adaptive Brake Lights warn following traffic in an
emergency braking situation with the following
actions:
R
By flashing the brake lamps
R
By activating the hazard warning lights
If the vehicle is braked sharply from speeds
above 50 km/h, the brake lamps flash rapidly.
This provides traffic travelling behind you with an
even more noticeable warning.
If the vehicle is travelling at speeds of more than
70 km/h at the beginning of the brake applica‐
tion, the hazard warning lights switch on once
the vehicle is stationary. When you pull away
again, the hazard warning lights will switch off
automatically at approximately 10 km/h. You
can also switch off the hazard warning lights
using the hazard warning button.
Cruise control and limiter
Function of cruise control
Cruise control regulates the speed to the value
selected by the driver.
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.
Cruise control is operated using the correspond‐
ing steering wheel buttons. You can store any
speed above 30 km/h up to the maximum
design speed or up to the set winter tyre limit.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recog‐
nise dangers (

A stored speed appears along with the h dis‐
play.
% The segments extending from the current
stored speed to the end of the scale, or to
the set winter tyre limit, light up in the
speedometer.
System limits
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 engine's brak‐
ing effect. This relieves the load on the brake
