All the turn signal lights on the vehicle flash at the same time when the hazard
warning light system is switched on. The warning light for the turn signals and
the warning light in the button also flash at the same time. The hazard warning
light system can also be operated if the ignition is switched off.
If one of the airbags is deployed, the hazard warning light system will switch on
automatically.
When the turn signal is switched on while the hazard warning light system is on
(ignition on), only the turn signal light for the selected driving direction will flash
while the turn signal is switched on.
Note
The hazard warning light system must be switched on if, for example:
you encounter a traffic congestion;
