Increasing Speed While Using Cruise Control
There are two ways to go to a higher speed:
D Use the accelerator pedal to get to the higher speed.
Press the SET/CST button, then release the button
and the accelerator pedal. You will now cruise at the
higher speed.
D Press the RES/ACC button. Hold it there until you
get up to the speed that you want, and then release
the button. To increase your speed in very small
amounts, briefly press the RES/ACC button and then
release it. Each time you do this, your vehicle will
speed up approximately 1 mph (1.6 km/h).
The accelerate feature will only work after you have set
the cruise control speed by pressing the SET/CST button.
Reducing Speed While Using Cruise Control
There are two ways to reduce your speed while using
cruise control:
D Press the SET/CST button until you reach the lower
speed you want, then release it.
D To slow down in very small amounts, push the
SET/CST button briefly. Each time you do this,
the vehicle will slow down approximately
1 mph (1.6 km/h).
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 your speed, load and the steepness of the hills.
When going up steep hills, you may have to step on the
accelerator pedal to maintain your speed. When going
downhill, you may have to brake or shift to a lower gear
to keep your speed down. Applying the brake or shifting
into a lower gear will take you out of cruise control. If
you need to apply the brake or shift to a lower gear due
to the grade of the downhill slope, you may not want to
attempt to use your cruise control feature.
Ending Cruise Control
To turn off the cruise control, step lightly on the brake
pedal, or press the CRUISE ON/OFF button on the
steering wheel.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.
