conditions.
Driving on sand and mud
First read and observe the introductoryinformation and safety warnings
Always drive at a steady speed through sand or mud and, do not carry out any manual gear changes
or stop the vehicle.
Check whether ESC is active. The indicator lamp or in the instrument cluster display must not
light up Brake support systems
Keep the vehicle moving constantly.
Use the Offroad driving profile S
Select a suitable gear and remain in this gear until you have reached more solid ground Changing
gear correctly
If the tyres have lost their grip, turn the steering wheel to and fro quickly. This can briefly give the
tyres on the front wheels better grip for these ground conditions.
Driving through sand
Do not under any circumstances reduce the tyre pressure to drive through sand
pressure has been reduced for driving through sand, the correct tyre pressure must always be
restored before driving on. Driving with reduced tyre pressure can lead to a loss of control over the
vehicle and increase the risk of serious and fatal injuries.
Driving through mud
Do not change speed or direction. The tyres can lose their traction when driving through mud. If the
vehicle slides, steer in the direction needed to get the vehicle under control.
WARNING
Driving through mud and sand can be dangerous. The vehicle can slide uncontrollably. This increases
the risk of injury. Always drive carefully through sand and mud.
Never choose an unsafe route or take a risk which could endanger you or your passengers. If you are
in any doubt about the safety of the route, turn round and choose another way.
WARNING
Incorrect tyre pressure can cause severe or even fatal accidents.
Incorrect tyre pressures will increase the levels of wear on the tyres and will negatively affect the
vehicle's handling.
