Setting Cruise Control
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The accelerator pedal will not go down.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course, shuts
off the cruise control. But you don't need to reset it.
The cruise light on the
instrument panel cluster will
come on when the cruise
control is engaged.
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control switch briefly from
on to resume/accelerate.
You'll go right back up to your chosen speed
and stay there.
If you hold the switch at resume/accelerate, the vehicle
will keep going faster until you release the switch or
apply the brake. So unless you want to go faster, don't
hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
•
Use the accelerator pedal to get to the higher
speed. Press the button at the end of the lever, then
release the button and the accelerator pedal.
You'll now cruise at the higher speed.
•
Move the cruise switch from on to resume/
accelerate. Hold it there until you get up to the speed
you want, and then release the switch. To increase
your speed in very small amounts, move the switch
briefly to resume/accelerate. Each time you do this,
your vehicle will go about 1 mph (1.6 km/h) faster.
