Slippery road surfaces

The outside temperature indicator is not WARNING
The outside temperature indicator is not designed to serve as an ice-warning device and is therefore unsuitable for that purpose.
Indicated temperatures just above the freezing point do not guarantee that the road surface is free of ice. The road may still be icy, especially in wooded areas or on bridges.

On slippery road surfaces, never downshift in WARNING
On slippery road surfaces, never downshift in order to obtain braking action. This could result in drive wheel slip and reduced vehicle control. Your vehicle's ABS will not prevent this type of loss of control.

Drive particularly carefully on slippery road surfaces. Avoid sudden acceleration, steering and braking maneuvers. Do not use the cruise control or DISTRONIC PLUS.

If the vehicle threatens to skid or cannot be stopped when moving at low speed:
– Shift the transmission to position N.

Make sure that you do not endanger other WARNING
Make sure that you do not endanger other road users when you apply the brakes.
