Driving on sand
When driving on sand, also observe the following
instructions:

R
ble. Make sure that the following prerequisites

ing:
Drive no faster than 6 mph (10 km/h).

and therefore vibrations.
If the F driving mode is selected: select
R
another driving mode.
Deactivate DSR.
R
Apply the brakes to dry them after fording.
R
Check that the service brake is working nor-
R
mally after a long downhill stretch.

tires, wheels and wheel arches
