2-37 Cruise Control
With cruise control, you can
maintain a speed of about
25 mph (40 km/h) or more
without keeping your foot
on the accelerator. This can
really help on long trips.
Cruise control does not
work at speeds below about
25 mph (40 km/h).
If you apply your brakes, the cruise control
will disengage.CAUTION:

Cruise control can be dangerous where you
can't drive safely at a steady speed. So,
don't use your cruise control on winding
roads or in heavy traffic.

Cruise control can be dangerous on
slippery roads. On such roads, fast changes
in tire traction can cause needless wheel
spinning, and you could lose control. Don't
use cruise control on slippery roads.
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 it.

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.
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 for about a half
a second.
You'll go right back up to your chosen speed and
stay there.
If you hold the switch at R/A longer than half a second,
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.

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 SET 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 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 small amounts, move the switch to R/A for less
than half a second. Each time you do this, your
vehicle will go about 1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise Control

Press and hold the SET button at the end of the lever
until you reach the lower speed you want, then
release it.

To slow down in very small amounts, press the SET
button for less than half a second. Each time you do
this, you'll go 1 mph (1.6 km/h) slower.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 want 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. Of course, applying the brake
takes you out of cruise control. Many drivers find this to
be too much trouble and don't use cruise control on
steep hills.
Ending Cruise Control
There are two ways to turn off the cruise control:

Step lightly on the brake pedal.

Move the cruise control switch to OFF.
Erasing Speed Memory
When you turn off the cruise control or the ignition,
your cruise control set speed memory is erased.
