If your vehicle is in cruise control when the enhanced
traction system begins to limit wheel spin, the cruise
control will automatically disengage. See Enhanced
Traction System (ETS) on page 4-10. When road
conditions allow you to safely use it again, you may
turn the cruise control back on.
Setting Cruise Control
If you leave your cruise control on when you're
not using cruise, you might hit a button and go
into cruise when you don't want to. You csuid
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. Push in the SET button at the end of the lever and
release it. The CRUISE light on the instrument
panel cluster will come on.
4. Take your foot off the accelerator pedal.
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.
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.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:

e
Use the accelerator pedal to get to the higher
speed. Push in the SET button, then release
the button and the accelerator pedal. You'll now
cruise at the higher speed.
Move the cruise switch from ON to R/A. Hold it there
until you get up to the speed you want, and then
release the switch. (To increase your speed in very

then release it. Each time you do this, your vehicle
will go about 1 mph (1 -6 km/h) faster.

cruise control speed by pushing the SET button.
