When you adjust a seat, you or other vehicle occupants could become trapped, e.g. on the seat guide rail.
Observe the safety notes on "Airbags" and "Children in the vehicle".
If the front-passenger seat backrest is folded forwards, persons in the rear compartment could collide with parts of the seat adjustment mechanism, particularly in the event of an accident, sudden braking or an abrupt change of direction.
The backrest of the front-passenger seat can be folded forwards to increase the luggage compartment capacity.
