Switching off the engine
Important safety notes
G WARNING
Never switch off the engine while the vehicle
is in motion.
There is no brake boost for the service brake
if the engine is not running. If the ignition is
switched off, there is also no power
assistance for the steering.
You will require considerably more effort to
steer and brake and you could therefore lose
control of the vehicle and cause an accident.
G WARNING
Keep in mind that turning off the engine alone
only will shift the automatic transmission into
neutral position N automatically.
Always shift the automatic transmission into
park position P before turning off the engine.
Otherwise the vehicle could roll away which
could result in an accident and/or serious
personal injury.
