Increasing Speed While Using Cruise
Control
There are two ways to go to a higher 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. Hold it there until the
desired speed is reached, and then release the
button. To increase the vehicle speed in small
amounts, press the RES+ button briefly and then
release it. Each time this is done, the vehicle goes
about 1.6 km/h (1 mph) faster.

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 cruise control speed you set earlier.
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, the accelerator pedal
might need to be applied to maintain the vehicle speed.
When going downhill, the brake might need to be
applied or the vehicle might have to be shifted to a lower
gear to keep the vehicle speed down. When the
brakes are applied the cruise control turns off.
Ending Cruise Control
To end cruise control, step lightly on the brake pedal or
the clutch pedal if the vehicle has a manual transmission.
Stepping on the brake pedal or clutch pedal will only
end the current cruise control session.

Erasing Speed Memory

the cruise control or the ignition is turned off.
