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.

Warning!
Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine

Excessive coolant temperature triggers a
warning in the multifunction display. The engine should not be operated with a
coolant temperature above 248‡
(120†). Doing so may cause serious
engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
