Hazard warning lamps
The hazard warning lamps automatically switch on if:
- an air bag is deployed.
- the vehicle is slowed down severely from a speed of over 45 mph(70 km/h) and comes to a halt.
- To switch on the hazard warning lamps: press button 1.
All turn signals flash. If you now switch on a turn signal using the combination switch, only the turn signal lamp on the corresponding side of the vehicle will flash. - To switch off the hazard warning lamps: press button 1.
The hazard warning lamps are deactivated automatically if the vehicle returns to a speed of over 6 mph(10 km/h) after a full application of the brakes.
The hazard warning lamps still operate if the ignition is switched off.
