GWarning
On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.
GWarning
Manual transmission: Wait until the vehicle is
stationary before removing the SmartKey
from the starter switch. The vehicle cannot be
steered when the SmartKey is removed from
the starter switch.
GWarning
It is dangerous to shift the automatic
transmission out of parking position P or
neutral position N if the engine speed is
higher than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.
! AMG vehicles: at low engine oil
temperatures (below 68 ‡ (+20 †), the
maximum engine speed is restricted in
order to protect the engine. To protect the
engine and maintain smooth engine
operation, avoid driving at full throttle when
the engine is cold.

following:
Rthe vehicle pulling away more gently in
forward and reverse gears, unless the
accelerator pedal is depressed fully
Rincreased sensitivity, which improves
driving stability on slippery road surfaces,
for example
Rthe automatic transmission shifting up
sooner, which results in the vehicle being
driven at lower engine speeds and the
wheels being less likely to spin
In drive program S, the automatic
transmission shifts up later.
