tems are unavailable due to a malfunction.
ATTENTION ASSIST is deactivated and other driving systems could be
automatically deactivated.
GWARNING
The brake system continues to function normally, but without the
functions listed above. The wheels could therefore lock if you brake
hard, for example.
This causes steerability and braking to be greatly impaired. The brak-
ing distance can increase in emergency braking situations.
If ESP

In addition, steam from an overheated engine can cause serious
burns, which can occur just by opening the hood.
There is a risk of injury.
XStop the vehicle immediately, paying attention to road and traffic
conditions, and switch off the engine.
XSecure the vehicle to prevent it from rolling away (Ypage 133).
XWait until the engine has cooled down.
XMake sure that the air supply to the radiator is not obstructed, by
frozen slush for example.
XDo not start the engine again until the display message goes out and
the coolant temperature is below the maximum value specified. The
engine could otherwise be damaged.
XPay attention to the coolant temperature gage (Ypage 173).
XIf the temperature increases again, visit a qualified specialist work-
shop immediately.
Under normal operating conditions and with the specified coolant
level, the coolant temperature gage may rise to 248 ‡ (120 †).
?The fan motor is faulty.
XCheck the coolant temperature (Ypage 173).
XIf the coolant temperature is below the maximum value specified
below, you can continue driving to the nearest qualified specialist
workshop.
Avoid heavy loads on the engine, e.g. driving in mountainous terrain,
and stop-and-go traffic.
Under normal operating conditions and with the specified coolant
level, the coolant temperature gage may rise to 248 ‡ (120 †).
