Otherwise, your vehicle could be damaged
or bottom out and get stuck.
Observe the following rules when driving
along ruts in off-road terrain or on roads with
loose gravel: R
Activate the off-road program
( Y
page 157). R
Avoid high engine speeds. R
Shift to a lower gear using the left-hand
steering wheel paddle shifter. R
Drive slowly. R
Where ruts are too deep, drive with the
wheels of one side on the center grassy
area, if possible.
Traveling uphill
Approach/departure angle
G WARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a
risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle. R
Observe the warnings for off-road driving
( Y
page 180). R
Follow the line of fall when driving on slopes
and steep inclines. R
Before driving on extreme uphill and down-
hill gradients, select the off-road program
( Y
page 157). R
Drive slowly. R
Accelerate gently and make sure that the
wheels are gripping. R
Avoid high engine speeds, except when
driving on sandy and muddy routes with
high driving resistance. R
Use the left-hand steering wheel paddle
shifter to shift to a lower gear appropriate
to the gradient. R
Use the left-hand steering wheel paddle
shifter to shift into a lower gear in good time
on long and steep downhill gradients.
Hill start assist will aid you when pulling away
on a hill. For further information about hill
start assist, see ( Y
page 153).
Do not switch to transmission position N
when driving off-road. If you try to brake the
vehicle using the service brake, you could
lose control of the vehicle. If the gradient is
too steep for your vehicle, drive back down in
reverse gear.
Always observe the approach/departure
angle values ( Y
page 384).
Maximum gradient-climbing capability Always observe the maximum gradient climb-
ing ability values ( Y
page 384).
Hilltops
When driving up an uphill gradient, slightly
reduce pressure on the accelerator immedi-
ately before reaching the brow of the hill.
Make use of the vehicle's own impetus to
travel over the brow.
This style of driving prevents: R
the vehicle from lifting off the ground on the
brow of a hill R
the vehicle from traveling too quickly down
the other side
Driving downhill R
Drive slowly. R
Do not drive at an angle down steep
inclines. Steer into the line of fall and drive
with the front wheels aligned straight. Oth-
erwise, the vehicle could slip sideways, tip
and rollover. R
Shift to a lower gear using the left-hand
steering wheel paddle shifter before tack-
ling steep downhill gradients. Driving tips 183

RACE START (AMG vehicles)
Important safety notes
i RACE START must not be used on normal
roads. RACE START must only be activated
and used on dedicated road circuits, out-
side of public road use.
i RACE START is only available in
Mercedes ‑ AMG vehicles.
G WARNING
If you use RACE START, individual tires may
start to spin and the vehicle could skid.
Depending on the selected ESP ®
mode, there
is an increased risk of skidding and having an
accident. Make sure that no persons, animals
or obstacles are within range of the vehicle.
RACE START enables optimal acceleration
from a standing start. For this, a suitably high-
grip road surface is required, along with the
tires and vehicle being in proper operating
condition. i Observe the safety notes on driving safety
systems ( Y
page 65).
Be sure to read the safety notes and infor-
mation on ESP ®
( Y
page 69).
