WARNING
Never drive with an overheated engine. Driving when your engine
is overheated can cause some fluids which may have leaked into
the engine compartment to catch fire.
In addition, steam from an overheated engine can cause serious
burns, which can occur just by opening the bonnet.
There is a risk of injury.
X
Stop the vehicle immediately, paying attention to road and traf-
fic conditions, and switch off the engine.
X
Safeguard the vehicle against rolling away (
Y
page 205).
X
Wait until the engine has cooled down.
X
Make sure that the air supply to the engine radiator is not
blocked, e.g. by frozen slush.
X
Do not start the engine again until the display message goes out
and the coolant temperature is below 120 †. The engine may
otherwise be damaged.
X
Pay attention to the coolant temperature display.
X
If the temperature increases again, consult a qualified specialist
workshop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature may rise to 120 †.
