Doors
The entire vehicle may be locked or
unlocked by using either the master
key in driver's door or trunk lock, or
central locking switch located in center
console. The central locking system
also locks or unlocks the fuel filler
flap.
Note:
If the fuel filler flap cannot be opened,
refer to Fuel Filler Flap, Manual
Release (see Index).
1. Opening - pull handle
2. Unlocking
3. Locking
4. Individual door from inside:
•
Push lock button down to lock.
•
Pull lock button up to unlock.
When you lock the car, both door lock
buttons should move down. If any one
stays up, the respective door is not
properly closed.
You should then unlock the car, open
and reclose this door, and lock the car
again. Each individual door can be
locked with door lock button - the
driver's door can only be locked when
it is closed.
If the car has previously been locked
from the outside, only the door being
opened from the inside will unlock,
and the alarm will come on. The other
door, the trunk lid and fuel filler flap
remain locked.
Note:
In case of a malfunction in the central
locking system the doors can be locked
and unlocked individually.
