PANIC
PANIC
If you unlock the vehicle but then do not open
any of the doors, the luggage compartment lid,
or the hood within a short period time, the vehi-
cle will lock again automatically. This feature pre-
vents the vehicle from being accidentally left un-
locked for a long period of time.

mine if the entire vehicle or only the driver's door
is unlocked when unlocking the vehicle
> page 23.

Z\ WARNING

are within view of the vehicle.

— The selector lever must be in the P position
on vehicles with a convenience key*; other-
wise the vehicle will not lock.
— Do not use the vehicle key to lock and un-
lock when you are inside the vehicle. Other-
wise, you could trigger the anti-theft
alarm. If this happens, press the fj unlock

or temperature could develop burns when
using the neck heating. To reduce the risk of
injury, these individuals should not use neck
heating.
— The output from the neck heating may be-
come very hot temporarily if the air vents in
the seats > fig. 87 are covered by clothing
or similar objects when the system is switch-
ed on. This can cause burns on unprotected
skin exposed directly to the vents.

Driving

Stopping the engine
> Bring the vehicle to a full stop.
> Press the [START ENGINE STOP] button.


Emergency off function*
If it is absolutely necessary, the engine can also
be turned off while driving at speeds starting at
4 mph (7 km/h). To stop the engine, press the
START ENGINE STOP] button twice in a row or


press and hold it one time.

Z\ WARNING
— Never turn off the engine before the vehicle
has come to a complete stop. Switching it
off before the vehicle has stopped may im-
pair the function of the brake booster and
power steering. 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 inju-
ries.
— If you leave the vehicle, switch the ignition
off and take the vehicle key with you. If you
do not do this, the engine could be started
and electrical equipment such as the power
windows could be activated. This can lead to
serious injuries.
— 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.
@) 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.
@) 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.
