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. 35 Driving Instrument cluster display Practical hints Car care Technical data Index Antitheft alarm system Instruments and controls Operation
