the tyre ruts are not too deep
-
the sand is firm enough
-
the ground clearance is sufficient
-
Lower the tyre pressure in all four wheels.
R
Contrary to the information on the tyre pres‐
sure plate (fuel filler flap), you can lower the
tyre pressure to 120 kPa (1.2 bar/17.4 psi).
Mercedes-AMG vehicles: observe the notes
in the Supplement. You could otherwise fail
to recognise dangers.
% Once you stop driving on sand, immediately
increase the tyre pressure again.
Information on the recommended tyre pres‐
sure for the vehicle's factory-fitted tyres can
be found on the tyre pressure table on the
inside of the fuel filler flap (
Fording
Also observe the following information when
fording:
Drive no faster than 10 km/h.
R
Observe the maximum permissible fording
R
depth ( page 415).

Before fording, shift the transfer case to the
R
LOW RANGE off-road gear (
Switch off automatic climate control

Driving in mountainous terrain
Also observe the following information when
driving in mountainous terrain:

Observe the values of the approach/depar‐
R
ture angle and of the maximum gradient
( page 415).

Use the braking power of the engine when
R
driving downhill.
Shift to a lower gear on uphill gradients and
R
on long, steep downhill gradients.
Checklist after driving off-road
Driving off-road places greater demands on your
vehicle than driving on normal roads. Check the
entire vehicle for damage and foreign bodies
every time after driving off-road. Foreign bodies
in the wheels or drivetrain can lead to imbalan‐
ces and therefore vibrations.
Shift the transfer case to the on-road posi‐
R
tion HIGH RANGE.
Disengage the differential locks.
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.
Clean the following components every time
R
after driving off-road:
