WARNING (continued)
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.
Caution
Avoid high engine speeds, full throttle and extreme load condi-
tions until the engine has reached its normal operating tempera-
ture, otherwise this can damage the engine.
The engine cannot be started by push-starting or towing.
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for about 2 minutes before
switching it off.
Switching off the engine with the Start/Stop
button
– Stop the vehicle.
– Automatic gearbox: Move the selector lever to position P
or N.
– Press the Start/Stop button ⇒ page 116, fig. 132.
Emergency Off function
Should it be necessary in an emergency, the engine can be switched
off when the selector lever is in position R, D or S. To switch off the
engine (max. speed 10 km/h) press and hold the Start/Stop button
and keep your foot on the brake.
WARNING
Never switch off the engine until the vehicle is stationary.
The brake servo and the power steering system work only
when the engine is running. You need more strength to steer and
brake the vehicle when the engine is switched off. This would
mean a greater risk of accidents and serious injury, because you
cannot steer and brake in the normal manner.
Caution
If the engine has been working hard for a long time, there is a risk
of heat building up in the engine compartment after the engine has
been switched off; this could cause engine damage. For this reason,
you should leave the engine idling for about 2 minutes before
switching it off.
Note
After the engine is stopped the radiator fan may run on for up to
10 minutes, even if the ignition is switched off. The fan may also
start running again after some time if the coolant temperature rises
due to a build-up of heat, or if the engine is hot and the engine
compartment is heated up further by direct sunlight.
