. Acoustic warnings if lights are not switched off
If the key is removed from the ignition lock and the driver door is opened, an acoustic warning will sound in any of the following situations. That will remind you to switch off the lights as necessary.
or
. Gas discharge bulbs
Gas discharge bulbs generate bright, uniform light for better illumination of the road. This also improves the visibility of the vehicle for other road users. The light from gas discharge bulbs is generated by passing a very high electrical current between two electrodes located in a gas-filled bulb.
The electrodes wear over time, which increases the distance between them. The control unit for the gas discharge bulbs detect this change and increases the electrical current to ensure that the generated light remains bright and uniform.
However, gas discharge bulbs can also blow. Before they blow, they may flicker or stop generating uniform light. Some vehicles (depending on the equipment level) may display a corresponding notification in the instrument cluster.
If the gas discharge bulbs flicker or stop generating uniform light, go to a qualified workshop immediately to have the headlights checked.
