CONTROLS
▷ Each time the rocker switch is pressed to the
resistance point, the desired speed is in‐
creased or decreased by 1 km/h, 1 mph.
▷ Each time the rocker switch is pressed be‐
yond the resistance point, the desired speed
changes to the next multiple of 10 km/h on
the km/h display or the next multiple of 5 mph
on the mph display in the speedometer.
The maximum speed which can be set de‐
pends on the vehicle.
▷ Pressing the rocker switch to the resistance
point and holding it there accelerates or de‐
celerates the vehicle without pressing the ac‐
celerator pedal.
The speed is maintained after releasing the
rocker switch. Pressing beyond the resist‐
ance point accelerates the vehicle more rap‐
idly.
Resuming Cruise Control
If Cruise Control is interrupted, it can be resumed
by calling up the saved speed.
Before calling up the saved speed, make sure
that the difference between the current speed
and the saved speed is not excessively large.
Otherwise, there may be inadvertent braking or
acceleration.
While the system is interrupted, press
the button.
Cruise Control is resumed with the saved values.
The saved speed value is deleted and can no
longer be called up in the following instances:
▷ When the system is switched off.
▷ When drive-ready state is switched off.
