Winter driving instructions
The most important rule for slippery or icy 
roads is to drive sensibly and to avoid 
abrupt acceleration, braking and steering 
maneuvers. Do not use the cruise control 
system under such conditions.
When the vehicle is in danger of skidding, 
move gear selector lever* to positionN or 
declutch in case of manual transmission. 
Try to keep the vehicle under control by 
corrective steering action.

On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of control loss.
