forced into the seat belt by a seat or back-
rest which is not engaged. The seat belt can no longer offer the intended level of pro-
tection and could even cause injuries.
R A child restraint system would no longer be
anchored or positioned correctly and would not be able to perform its required function.
R The seat backrests cannot restrain objects
or loads in the cargo compartment.
There is an increased risk of injury.
Always make sure that the seat and backrest are engaged as described:
R before traveling with a passenger on a seat
with the EASY-ENTRY/EXIT feature
R after you have adjusted the seat
R after the EASY-ENTRY/EXIT feature has
been used
R after the cargo compartment enlargement
