Warning!G
The seat belts provide protection only with
the backrest locked in place. Therefore, the
backrest must be locked in place with the
vehicle in motion. Do not drive the vehicle
when the backrest is not locked in place.
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.
The power seats can also be operated with
the driver’s or passenger door open. Do not
leave children unattended in the vehicle or
with access to an unlocked vehicle. Unsu-
pervised use of vehicle equipment may
cause an accident and/or serious personal
injury.
Never place hands under seat or near any
moving parts during a seat adjustment
procedure.
Warning!G
Do not adjust the steering wheel while driv-
ing. Adjusting the steering wheel while driv-
ing could cause the driver to lose control of
the vehicle.
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.
Even with the SmartKey or SmartKey with
KEYLESS-GO* removed from the starter
switch, or the SmartKey with KEYLESS-GO*
removed from the vehicle, the steering
wheel adjustment feature can be operated
when the driver’s door is open. Therefore,
do not leave children unattended in the ve-
hicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may
cause an accident and/or serious personal
injury.

til it engages.
Check the rear seat backrest to be
locked in its upright position
(
page 282).
When the child restraint is not in use,
remove it from the vehicle or secure it with
the seat belt to prevent the child restraint
from becoming a projectile in the event of
an accident.
Do not leave children unattended in the
vehicle, even if the children are secured in a
child restraint system. Unsupervised
children in a child restraint system may use
vehicle equipment and may cause an
accident and/or serious personal injury.
iYour CLK cabriolet does not have and is not
required to have anchorage rings for a child
seat’s top tether strap in the rear seating posi-
tions. Child seats can be used with the seat belt,
or lower anchor system and seat belt, fully in ac-
cordance with the child seat manufacturer’s in-
structions.
iFor safety, make sure the hook2 has at-
tached to the anchorage ring1 beyond the
safety catch, as illustrated.
