Overheating in the engine and
drive system
Under certain conditions, e.g. hard driving in
hilly terrain and hot climate, there is a risk
that the engine and drive system may over-
heat – in particular with a heavy load.
In the event of overheating, the engine's
•
power may be limited temporarily.
Remove any auxiliary lamps from in front
•
of the grille when driving in hot climates.
If the temperature in the engine's cooling
•
system becomes too high then a warning
symbol is illuminated and the driver dis-
play shows the message
Engine
temperature High temperature Stop
safely
. Stop the car in a safe way and
allow the engine to run at idling speed for
several minutes and cool down.
If the message

is shown, stop the car and switch
off the engine.
In the event of overheating in the gearbox,

an alternative gear shift program will be
selected. In addition, a built-in protection
function is activated that, amongst other
things, illuminates a warning symbol and
the driver display shows the message

recommendation given, reduce speed or
stop the car in a safe way and allow the

Do not turn the engine off immediately
