Reducing Speed While Using
Cruise Control
If the cruise control system is
already activated,
Press and hold the SET button
on the steering wheel until the
desired lower speed is reached,
then release it.
To slow down in small amounts,
press the SET button on the
steering wheel 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 your speed. When you
take your foot off the pedal, the
vehicle will slow down to the
previous set cruise speed.

Using Cruise Control on Hills

How well the cruise control works
on hills depends upon 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 keep the
vehicle speed down. When the
brakes are applied the 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.
Press the button on the
steering wheel.
To turn off the cruise control,
press on the steering wheel.
Erasing Speed Memory
The cruise control set speed is
erased from memory by pressing
the button or if the ignition is
turned off.
