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.
! Do not run a cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service life
of the engine. This is not covered by the
Mercedes-Benz Limited Warranty.
Drive off immediately after starting the
engine to warm up the engine efficiently.
The engine must be at operating
temperature before using full engine
power. The engine has reached operating
temperature once the engine oil
temperature indicator in the AMG menu of
the control system has stopped flashing.
At engine temperatures below 32‡ (0†),
the engine’s maximum speed is restricted
in order to protect it from damage. Avoid
driving your vehicle at full speed when the
engine is cold to prevent premature engine
wear and/or diminished comfort.
