remaining in the vehicle might be
able to lock the doors from the inside,
always take the vehicle's keys with you

from the outside at any time.<

the vehicle via the remote control,
the battery is discharged. Use this key

three-point safety belt – except for the
driver's seat – are suitable for installing

headrest and the seat back.
It is recommended to readjust the head
restraint in the lowest possible position.

child-restraint manufacturer's instruc-
tions.
