Checking The Vehicle's Status (Applies Only To Vehicles With Keyless Function Installed)

The vehicle's status can be checked via the remote control. The checks are activated using the information button on the remote key. During activation, the remote key transmits a signal to the vehicle, which:

activates the heartbeat sensor (structure week -2010 20-), to check if anybody is in the vehicle
checks the central locking system status, if the vehicle is locked or not
checks the alarm status, if the vehicle alarm has been activated or not.

The result is transmitted to the remote key and indicated there by LEDS. There are four LEDs on the remote key:

Green LED Indicates that the central locking system is in the locked position.
Yellow LED Indicates that the central locking system is unlocked.
Red LED (long) Indicates that the vehicle's alarm has been activated during this lock cycle.
Red LED (short) Indicates that the heartbeat sensor has detected somebody in the vehicle (structure week -201020).

If it is indicated that someone is in the vehicle, LEDs 3 and 4 will flash alternately (structure week -201020). For later structure weeks this indication means that the alarm has been triggered during the past 5 minutes.

To clarify the signals from the remote key, only the warning/status that is considered to be the most relevant is displayed during the status check.

If the status check shows that the heartbeat sensor indicates that somebody is in the vehicle, only the warning will be displayed (no information display about the central locking status or if the alarm has been activated earlier). Applies to vehicles with heartbeat sensor.
If the status check shows that the vehicle is locked but that the alarm has been activated during the last 5 minutes, only the warning will be displayed (no information display about the central locking status or if the alarm has been activated earlier). Applies to vehicles without heartbeat sensor.
If the status check indicates that the vehicle is locked but that the alarm has been activated during the lock cycle, only the warning for activated alarm is shown (information about central locking system status is not displayed).
If the status check indicates that the vehicle is locked without the alarm being deployed, the central locking system status is displayed.

NOTE: The heartbeat sensor does not trigger the alarm functions in the vehicle. The sensor only indicates that somebody is in the vehicle in the event of a request from the remote key/Volvo Personal Communicator.

If the information button is pressed when the vehicle is outside the remote key's range, the last status received from the vehicle is indicated on the remote key.

The remote key contains an internal battery that is used every time information is transmitted from, or managed by, the remote key. For example, unlocking using the lock button, keyless unlocking/locking and start or status check. The battery in the remote key has a limited service life and may need replacing. If the remote key's battery becomes weak, a message will be displayed in the driver information module (DIM). Another indication that the remote key's battery is almost drained is that the range of the remote key starts to reduce and the button needs to be depressed for longer to carry out a function.
