Resuming a Set Speed
If the brakes are applied while the
cruise control is at a set speed, the
cruise control disengages. But it
does not need to be reset.

speed selected previously and stays

Driving and Operating
Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed. Disengage the cruise
control, but do not turn it off.
If the cruise control system is
already engaged, move the
thumbwheel up toward RES/+
and hold it until the vehicle
accelerates to the desired
speed, and then release it.
To increase the speed in small
amounts, move the thumbwheel
up toward RES/+ briefly and
then release it. Each time this is
done, the vehicle goes about
1.6 km/h (1 mph) faster.
