Setting Cruise Control
CAUTION:
If you leave your cruise control switch on when
you're not using cruise, you might hit a button
and go into cruise when you don't want to. You
could be startled and even lose control. Keep the
cruise control switch off until you want to use
cruise control.
1. Move the cruise control switch to ON.
2. Get up to the speed you want.
3. Press in the SET button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.

The CRUISE light on the instrument panel will
illuminate when the cruise control is engaged.
Resuming a Set Speed
Suppose you set your cruise control at a desired speed and
then you apply the brake. This, of course, disengages the
cruise control. But you don't need to reset it.
Once you're going about 25 mph (40 km/h) or more,
you can move the cruise control switch from ON to
R/A (Resume/Accelerate) briefly.
You'll go right back up to your chosen speed and
stay there.
If you continue to hold the switch at R/A, 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 R/A.
