Operation
7. Always take the vehicle key with you when you l eav
e the vehicle.
All turn signals flash simultaneously when the
hazard warning lights are switched on. The
two turn signal turn signal lamps   and the
turn signal lamp in the switch  will flash at
the same time. The simultaneous hazard
warning lights also work when the ignition is
switched off.
Emergency braking warning
If the vehicle brakes suddenly and continu-
ously at a speed of more than 80 km/h (50
mph), the brake light flashes several times per
second to warn the vehicles driving behind. If
you continue braking, the hazard warning
lights will come on automatically when the
vehicle comes to a standstill. They switch off
automatically when the vehicle starts to
move again. WARNING
