Increasing Speed While Using
Cruise Control
There are two ways to increase speed.
1. Disengage the cruise control by applying the brake
pedal but do not turn it off. Accelerate to a higher
speed and reset the cruise control.
2. If the cruise control system is already engaged,
press the RES+ button. Press it until you get up
to the speed you want, and then release the button.
To increase your speed in very small amounts,
press the RES+ button briefly and then release it.
Each time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using
Cruise Control
If the cruise control system is already engaged,
•
Push and hold the SET− part of the button until
you reach the lower speed desired, then release it.
•
To slow down in very small amounts, push
the SET− part of the button briefly. Each time
this is done, your vehicle will go about 1 mph
(1.6 km/h) slower.

Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
Using Cruise Control on Hills
How well your cruise control will work 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.
Of course, applying the brake turns off the cruise control.
Many drivers find this to be too much trouble and do
not use cruise control on steep hills.
Ending Cruise Control
To end cruise control, step lightly on the brake pedal or the
clutch pedal if your vehicle has a manual transmission.
Stepping on the brake pedal or clutch pedal will only end
the current cruise control session. Press the cruise
control on/off button to turn the system completely off.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
the cruise control set speed memory is erased.
