WARNING
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. G
WARNING
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

temperature more quickly. Hill start assist G
WARNING
Never leave the vehicle when it is being held
by hill start assist. After approximately one
second, hill start assist will no longer brake
your vehicle and it could roll away.
Hill start assist helps you when pulling away
forwards or in reverse on an uphill gradient.

from the brake pedal to the accelerator pedal
and to depress it before the vehicle begins to
roll.
