Antitheft alarm system
The indicator lamp is located in the center console.
The antitheft alarm is automatically armed or disarmed
with the remote control by locking or unlocking the
vehicle.
The antitheft alarm is armed within approximately
15 seconds after locking the vehicle with the remote
control.
A blinking lamp in the center console indicates that the
alarm is armed.
Notes:
Use of the key in the front door locks does not arm or
disarm the antitheft alarm system.
The alarm sounds when unlocking the driver’s door
with the mechanical key. Cancel alarm by turning key in
steering lock to position 1, or with the remote control by
pressing button Œ.
If the vehicle battery voltage falls below 10 volts, the
alarm is automatically canceled and the antitheft alarm
system is disarmed. When the voltage is above this
value again, the antitheft alarm system is armed again. Operation:
Once the alarm system has been armed, the turn signal
lamps will flash rapidly (approximately 3 minutes) and
the horn will sound intermittently (approximately
30 seconds) when someone:
• opens a door,
• opens the liftgate,
• opens the hood,
• breaks a window,
• attempts to raise the vehicle.
The alarm will stay on even if the activating element (a
door, for example) is immediately closed.
If the alarm stays on for more than 20 seconds, an
emergency call is initiated automatically. See Tele Aid
on page 148.
Note:
The alarm system will cycle three times when triggered.
The interior lights are automatically switched on when
the alarm comes on and go out when canceling the
alarm.
