R
Do not drive on unknown terrain that is not
easily visible and stay on marked routes.
R
Always keep the doors and windows closed
while the vehicle is in motion.
R
Deactivate Active Distance Assist DISTRONIC
and cruise control.
R
Adapt your driving style to the terrain.
R
Do not use the HOLD function on steep
downhill or uphill gradients with slippery or
loose surfaces.
Driving on sand
When driving on sand, also observe the following
instructions:
R
Shift to a lower gear.
R
Drive quickly to overcome the rolling resist‐
ance, otherwise the vehicle may dig itself in.
R
Drive in the tracks of other vehicles if possi‐
ble. Make sure that the following prerequi‐
sites are met:
-
The tire ruts are not too deep
-
The sand is firm enough
-
The ground clearance is sufficient
R
Lower the tire pressure in all four wheels.
Contrary to the information on the tire pres‐
sure plate (fuel filler flap), you can lower the
tire pressure to 120 kPa (1.2 bar/17. 4 psi).
Mercedes-AMG vehicles: observe the notes in
the Supplement. Otherwise, you may fail to rec‐
ognize dangers.
%
Once you stop driving on sand, immediately
increase the tire pressure again.
You can find information on tire pressure for
the vehicle's factory-installed tires on the
following labels:
R
Tire and Loading Information placard on
the B‑pillar of your vehicle (/ page 391).
R
Tire pressure table on the inside of the
fuel filler flap (/ page 387).
Fording
Also observe the following information when
fording:
R
Drive at no more than 6 mph (10 km/h).
R
Observe the maximum permissible fording
depth (/ page 424).
R
Before fording, shift the transfer case to the
LOW RANGE off-road gear (/ page 149).
R
Switch off automatic climate control
(/ page 126).
R
Ensure that a bow wave does not form as you
drive.
R
Do not stop in the water and do not switch
off the engine. Ensure the ECO start/stop
function is switched off (/ page 140).
Driving in mountainous terrain
Also observe the following information when
driving in mountainous terrain:
R
Observe the values of the approach/depar‐
ture angle and of the maximum gradient
(/ page 424).
R
Engage the differential locks if necessary
(/ page 151).
R
Avoid high engine speeds.
R
Use the braking power of the engine when
driving downhill.
R
Shift to a lower gear on uphill gradients and
on long, steep downhill gradients.
