Unlocking:
Press transmit button Œ. All turn signal lamps blink 
once to indicate that the vehicle is unlocked.
The remote control can be programmed for two kinds of 
unlocking modes (see below):
Selective unlocking mode –
Press transmit button Œ once to unlock driver’s door, 
storage compartment in armrest, and fuel filler flap.
Press transmit button Œ twice to unlock both doors, 
storage compartment in armrest, fuel filler flap, and 
trunk.
Global unlocking mode –
Press transmit button Œ  once to unlock both doors, 
storage compartment in armrest, fuel filler flap, and 
trunk.
Notes:
If the trunk was previously locked separately, it will 
remain locked, see page 39.
The presently active unlocking mode (selective or 
global) can only be determined by unlocking the vehicle 
with the remote control (see below for changing mode).If within 40 seconds of unlocking with the remote 
control, neither door is opened, the key is not inserted 
in the steering lock, or the central locking switch is not 
activated, the vehicle will automatically lock.
Locking:
Press transmit button ‹ once. All turn signal lamps 
blink three times to indicate that the vehicle is locked.
Note:
If the vehicle cannot be locked or unlocked by pressing 
the transmit button, then it may be necessary to change 
the batteries in the remote control (if ok, battery check 
lamp in transmitter will light briefly when transmitting) 
or to synchronize the remote control, see page 251 and 
page 252.
