Off-road driving program
The off-road driving program is designed to
assist the driver when driving off-road in
terrain and crossing water. The off-road
driving program adjusts the engine power
and shifting of the automatic transmission
to be more suitable for the off-road use of
the vehicle. In addition, the ABS, ESP
®,
and 4-ETS designed for off-road use are
automatically activated.
In the following situations you should
switch to the Off-road driving program:


during off-road driving


when crossing water


when towing up or down on steep
gradientsThe switch is located on the lower part of
the center console.

or the lower the temperature it can tol-
erate without becoming viscous, the
better the viscosity.
