Off-road drive program

The off-road drive program is only
available on vehicles without the Off-Road
Pro Engineering package.
The off-road drive program assists you when
driving off-road. The engine's performance
characteristics and the gearshifting
characteristics of the automatic transmission
are adapted for this purpose. ABS, ESP
4ETS programs especially adapted to off-road
driving are also activated.
Do not use the off-road drive program on
roads that are snowy or icy or if your vehicle
has snow chains mounted.
