Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in
motion if, for example, they:
Rrelease the parking brake.
Rshifting the automatic transmission out of
park position P
RStart the engine.
There is arisk of an accident and injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children or animals unattended in the
vehicle. Always keep the SmartKey out of
reach of children.
GWARNING
If you attach heavy or large object stothe
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large object stothe
SmartKey. Remove any bulky key rings before
insertingt he SmartKey into the ignition lock.
!Keep the SmartKey away from stron gmag-
netic fields. Otherwise, the remote control
function could be affected.
Strong magnetic fields can occur in the vicin-
ity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. amobile phone
or another SmartKey.
Rwith metallic objects, e.g. coins or metal foil.
Rinside metallic objects, e.g. ametal case.
This can affect the functionality of the Smart- Key. Vehicles with KEYLESS-GO startf
unction:do
not keep the SmartKey on the parcel shelf or in
the trunk.O therwise, the SmartKey may not be
detected, e.g. when startin gthe engine using
the Start/Stop button.
Ac heck which periodically establishes aradio
connection between the vehicle and the Smart-
Key determines whether avalid SmartKey is in
the vehicle. This occurs, for example:
Rwhen startin gthe engine
Rwhile driving
Rwhen the external door handles are touched

Bear in mind that the engin ecan be started by
any of the vehicle occupant sifthere is aSmart-
Key in the vehicle (

Locking/unlocking centrally
You can start, lock or unloc kthe vehicle using
KEYLESS-GO. To do this ,you only need carr ythe
SmartKey with you. You can combine the func-

tional SmartKey. Unlock the vehicle by using
KEYLESS-GO, for instance, and lock it using the
& button on the SmartKey.
The driver's door and the door at which the han-
dle is used, must both be closed. The SmartKey
must be outsid ethe vehicle. When locking or
unlockin gwith KEYLESS-GO, the distance
betwee nthe SmartKey and the corresponding
door handle must not be greater than 3ft(1m ).
Ab rief radio connection betwee nthe vehicle
and the SmartKey determine swhether avalid
