Cruise Set Indication (Green)
The indication turns on (green) when a
cruising speed has been set.
▼Activation/Deactivation
WA R N I N G
Always turn
off the cruise control system
when it is not in use:
Leaving the cruise control system in an
activation-ready state while the cruise
control is not in use is dangerous as the
cruise control could unexpectedly activate
if the activation button is accidentally
pressed, and result in loss of vehicle control
and an accident.
NOTE
When the ignition is switched OFF, the
system status before it was turned off is
maintained. For example, if the ignition is
switched OFF with the cruise control
system operable, the system will be
operable when the ignition is switched ON
the next time.
Activation
To activate the system, press the cruise
switch. The cruise standby indication
(white) turns on.
