!Make sure the seat belt retracts fully so that
the seat belt and/or latch plate cannot get
caught or pinched in the door or in the seat
mechanism. This can damage the seat belt and
impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim pan-
el. Such damage is not covered by the
Mercedes-Benz Limit Warranty.
Damaged seat belts must be replaced. Contact
an authorized Mercedes-Benz Center.
Warning!G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are

Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an

cess to a vehicle could result in an accident
and/or serious personal injury.
