XPull over and stop the vehicle safely and switch off the engine, pay- ing attention to road and traffic conditions.
XSecure the vehicle against rolling away (Ypage 137).
XWait until the engine has cooled down.
XMake sure that the air supply to the engine radiator is not blocked,e.g. by snow, slush or ice.
XDo not start the engine again until the display message goes out and
the coolant temperature is below 257 ‡ (125 †). Otherwise, the
engine could be damaged.
XPay attention to the coolant temperature gauge.
If the temperature increases again:
