partment lid as well as the vehicle doors

A WARNING
- Never turn off the engine before the vehicle
has come to a complete stop. The full func­
tion of the brake booster and the power
steering is not guaranteed. You may need to
use more force when braking or steering.
Because you cannot brake and steer as you
usually would, this could lead to accidents
and serious injuries.
- If you leave the vehicle, switch the ignition
off and take the vehicle key with you . Other­
wise, the engine could be started or electri­
cal equipment such as the power windows
could be operated. This can lead to serious
injury.
- For safety reasons, always park the vehicle
with the selector lever in the P position .
Otherwise, there is the risk that the vehicle
could roll unintentionally.
0 Note
If the engine has been under heavy load for
an extended period of time, heat builds up in
the engine compartment after the engine is
switched off and there is a risk of damaging
the engine. For this reason, let the engine run
at idle for approximately two minutes before
shutting it off .
(D Tips
For up to 10 minutes after stopping the en ­
gine, the radiator fan may turn on again auto­
matically or it may continue to run (even if
the ignition is switched off) for the following
reasons:
- The coolant temperature is increasing due
to trapped heat.
- If the engine is warm and the engine com­
partment also heats up from strong sun­
light.
