loose floormats and do not place several floor- mats on top of one another. G
WARNING
Unsuitable footwear can hinder correct usage of the pedals, e.g.:
R shoes with thick soles
R shoes with high heels
R slippers
There is arisk of an accident.
Wear suitable footwear to ensure correct
usage of the pedals. G
WARNING
If you switch off the ignition while driving,
safety-relevant functions are only available
with limitations, or not at all. This could affect, for example, the power steering and the brake
boosting effect. You will require considerably
more effort to steer and brake. There is arisk
of an accident.
Do not switch off the ignition while driving. G
WARNING
If the parking brake has not been fully
released when driving, the parking brake can:
R overheat and cause afire
R lose its hold function.
There is arisk of fire and an accident. Release
the parking brake fully before driving off.
! Do not warm up the engine when the vehi-
cle is stationary. Drive off immediately.
Avoid high engine speeds and driving at full throttle until the engine has reached its
operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle is stationary.
Where possible,a void spinning the drive
wheels when pulling awayons lippery
roads. You could otherwise damage the
drive train. !
AMG vehicles:
at low engine oil temper-
atures (below +20 †), the maximum
engine speed is restricted in order to pro-
tect the engine. To protect the engine and
maintain smooth engine operation, avoid
driving at full throttle when the engine is
cold.

sion: upshifts tak eplace at higher engine
speeds after acold start .This helps the
catalytic converter to reach its operating
temperature more quickly.
Hill start assist Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient .It
holds the vehicle for ashort time after you
have removed your foot from the brake pedal.
This gives you enough time to move your foot from the brake pedal to the accelerator pedal and depress it before the vehicle begins to
roll. G
WARNING
After ashort time, hill start assist will no lon-
ger brake your vehicle and it could roll away.
There is arisk of an acciden tand injury.
Therefore, quickly move your foot from the
brake pedal to the accelerator pedal. Never
leave the vehicle when it is held by hill start
assist.
Hill start assist is not activ eif:
