impair the effectiveness of the seat belt, and/or
cause damage to the door and/or door trim
panel. Such damage is not covered by the
Mercedes-Benz Limited 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

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 from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child’s
unsupervised access to a vehicle could
result in an accident and/or serious
personal injury.
Warning!G
