Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Driver Information Module (Dim)
The driver information module (DIM) (5/1) displays a text message and lights a warning lamp if any of the side doors or tailgate/trunk lid or hood have been opened whilst driving. A micro-switch indicates that the doors or tailgate/trunk lid are fully closed. Only cars with an alarm have a contact breaker at the engine hood.
A yellow warning lamp lights if the vehicle speed is below 7 km/h (5 mph). The red warning lamp lights if the vehicle speed is above 7 km/h (5 mph).
The tailgate is only indicated by a text message and yellow warning lamp, irrespective of the speed.
The driver information module (DIM) shows the message in its displays if:
- the driver's door is opened and the vehicle is in ignition position I-III. The display shows what needs to be done to switch off the ignition
- if the gear selector is not in position P and an attempt is made to remove the remote key form the starter module
- the electrical child-proof lock is activated or deactivated
- valet locking of the glove compartment and cargo compartment is activated or deactivated
- the remote key transmits a warning to the vehicle about low battery voltage for the remote key.
