9-34 Driving and Operating
Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated:
Move the thumbwheel toward
SET/ and hold until the desired
lower speed is reached, then
release it.
To slow down in small amounts,
move the thumbwheel toward
SET/ briefly. Each time this is
done, the vehicle goes about
1.6 km/h (1 mph) slower.
Passing Another Vehicle While
Using Cruise Control
Use the accelerator pedal to
increase the vehicle speed. When
you take your foot off the pedal, the
vehicle slows down to the previous
set cruise control speed.
Using Cruise Control on Hills
How well cruise control works on
hills depends on the vehicle speed,
load, and the steepness of the hills.
When going up steep hills, you
might have to step on the
accelerator pedal to maintain the
vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied, cruise control is
disengaged.
Ending Cruise Control
There are three ways to end cruise
control:
To disengage cruise control,
step lightly on the brake pedal or
clutch for manual transmission.
Press on the steering wheel.
To turn off cruise control, press
on the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory if the
is pressed or if the ignition is
turned off.
