Important safety notes G
WARNING
If the backrest is not engaged, it could fold
forwards during a braking manoeuvre or in the event of an accident, for example. The seat
backrest will then push the vehicle occupant
against the seat belt. The seat belt cannot
protect as intended and could result in addi-
tional injury. This poses an increased risk of
injury.
Before each journey, make sure that the back- rest engages fully as described. G

body within the sweep of the seat when
adjusting it. Folding the seat backrest forwards With the EASY-ENTRY system, the seat moves
forwards if you have folded the backrest for-
wards and the seat is in the rear half of the

ment.
The head restraint also lowers on vehicles with
electric seat adjustment.
