LESS GO* key. For this reason, children
should never be left unsupervised in the vehi-
cle. Always take the key with you when leaving

wheels when pulling away on slippery
roads. Otherwise, you could damage the
drive train.
! AMG vehicles: at low engine tempera-
tures (below +20 †), the maximum engine
speed is restricted in order to protect the

i Upshifts take place at higher engine
speeds after a cold start. This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
on uphill gradients. It holds the vehicle for a
short time after you have removed your foot
from the brake pedal. This gives you time to
move your foot from the brake pedal to the
accelerator pedal and depress it before the
vehicle begins to roll. G
Risk of accident
Never leave the vehicle when it is held by hill
start assist. After approximately one second,
hill start assist will no longer brake your vehi-
cle and it could roll away.
X Take your foot off the brake pedal.
i Once you have taken your foot off the
brake pedal, the vehicle is held for around
one second.
X Pull away. Hill start assist will not function if:

Risk of accident
Only remove the key from the ignition lock
when the vehicle is stationary, as you cannot
steer the vehicle with the key removed.
Never leave children unsupervised in the vehi-
cle. They might release the electric parking
brake. This could lead to a serious or fatal
accident. G
Risk of fire
Make sure that the exhaust system does not
under any circumstances come into contact
with flammable materials such as dry grass or
petrol. The material could otherwise ignite
and set the vehicle on fire.
To ensure that the vehicle is secured against
rolling away unintentionally:
R the parking brake must be applied
R move the DIRECT SELECT lever into posi-
tion Pand remove the ignition key
R for steep uphill or downhill gradients, turn

others.
Therefore, do not switch off the engine while
you are driving.

Notes on the transmission
G
Risk of accident
The movement of the pedals must not be
impaired in any way. Do not keep any objects
in the driver's footwell. Make sure that floor-
mats or carpets are correctly secured and
that there is sufficient clearance for the ped-
als.
Do not place several floormats on top of one
another. G
Risk of accident
Do not change down for additional engine
braking on a slippery road surface. This could
cause the drive wheels to lose their grip and
the vehicle could skid. This could cause you
to lose control of your vehicle and cause an
accident. Automatic transmission
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only set the automatic transmission to the
respective drive positions when the vehicle

Vehicle level Your vehicle automatically adjusts its ride
height to reduce petrol consumption and
improve driving safety.
Depending on the vehicle height that has
been set, the vehicle automatically adjusts its
height dependent on the current speed. The
vehicle is lowered by up to 10 mm as the
speed increases. As the speed is reduced, the
vehicle is raised up to the set vehicle height. G
Risk of injury
The vehicle is lowered when the engine is
switched off. Therefore, make sure that
nobody is in the vicinity of the wheel housing
or under the vehicle when you switch off the
engine. Otherwise, limbs could become trap-
ped.
! The vehicle is lowered by about 5 mm
when the engine is switched off. When
parking, make sure that you stop your vehi-
cle so that it does not make contact with
the kerb as it is lowered. Otherwise, the
vehicle could be damaged.
Setting the vehicle level manually
Select the "Normal" setting for normal road
surfaces and "Raised" for driving with snow
chains or on particularly poor road surfaces. G
Risk of injury
Make sure that nobody is in the vicinity of the
wheel housing or under the vehicle while low-
ering the vehicle when it is stationary. Other-
wise, limbs could become trapped. X
