that the engine and drive system may overheat -
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.

system becomes too high then a warning
symbol is illuminated and the driver display
shows the message
