Alarm system

The alarm system in the BMW 5 Series (G30) reliably protects against break-in, towing or tampering. This section explains how it works, the security options and how to deactivate individual sensors. It also covers window lifters, anti-trap protection and child safety switches, for comprehensive vehicle security.

General

When the vehicle is locked, the alarm system responds to the following changes:

• Opening a door, the bonnet or the tailgate.
• Movement inside the vehicle.
• Changing the vehicle's angle, e.g. when attempting to steal a wheel or during towing.
• Interruption of the battery voltage.
• Improper use of the on-board diagnostics (OBD) socket.

The alarm system signals these changes visually and audibly:

• Audible alarm.
• Hazard warning lights switch on.

Arming and disarming

The alarm system is armed and disarmed at the same time as the vehicle is locked and unlocked using the remote control or Comfort Access.

Opening doors while the alarm system is armed

The alarm system triggers when a door is opened if it was unlocked with the integrated key via the door lock.

Stop the alarm.

Opening the tailgate while the alarm system is armed

The tailgate can also be opened while the alarm system is armed.

When the tailgate is closed, it is locked again and monitored, provided the doors are locked. The hazard warning lights flash once.

Indicator lamp on the interior rearview mirror

• Indicator lamp flashes every 2 seconds: the alarm system is armed.
• Indicator lamp flashes for approx. 10 seconds before flashing every 2 seconds: interior monitoring and tilt alarm sensor are not active because a door, the hood or the tailgate is not properly closed. Properly closed access points are secured.

If any open access points are still open, they are closed and the interior monitoring and tilt alarm sensor are switched on.

Indicator lamp goes out after unlocking: the vehicle has not been tampered with.

After unlocking, the indicator lamp flashes until ready-to-drive mode is switched on, but for no more than approx. 5 minutes: the alarm has been triggered.

Tilt alarm sensor

Monitors the vehicle's angle.

The alarm system responds, e.g. when attempting to steal a wheel or during towing.

Interior monitoring

For proper function, the windows and the glass roof must be closed.

Avoiding unintended alarms

General

The tilt alarm sensor and interior monitoring can trigger an alarm even when there is no unauthorized activity.

Possible situations for an unintended alarm:

• In car washes or automatic washing systems.
• In duplex garages.
• When transported on car-carrying trains, by sea or on a trailer.
• When animals are in the vehicle.

In such situations, the tilt alarm sensor and interior monitoring can be switched off.

Switching off the tilt alarm sensor and interior monitoring

Press the button on the remote control again within 10 seconds, as soon as the vehicle is locked.

Indicator lamp lights up for approx. 2 seconds and then continues to flash.

The tilt alarm sensor and interior monitoring remain switched off until the vehicle is locked again.

Stopping the alarm

• Unlock the vehicle with the remote control, if necessary via emergency recognition of the remote control.
• With Comfort Access: if the remote control is carried, grip the driver's or front passenger's door handle fully.

Window lifters
