hazard warning flasher in use, set the starter
switch to position2 and activate combination
switch for left or right turn signal in usual manner
– only the selected turn signal will operate.

doors lock if the left front wheel is turning at a
speed of approximately 9 mph (15 km/h) or
above.
To prevent the vehicle doors from locking,
deactivate the automatic central locking
(
page 126).
Towing of the vehicle should only be done using
the towing eye bolt. Never attach tow cable, tow
rope or tow rod to vehicle chassis, frame or sus-
pension parts.
