Setting Cruise Control
Cruise control will not work if your parking brake
is set, or if the master cylinder brake fluid
level is low.
The cruise control light on the instrument panel
cluster comes on after the cruise control has
been set to the desired speed.
CAUTION:
{
If you leave your cruise control on when
you are not using cruise, you might hit a
button and go into cruise when you do not
want to. You could be startled and even
lose control. Keep the cruise control switch
off until you want to use cruise control.
1. Press the cruise control on/off button.
2. Get up to the speed desired.
3. Press and release the SET– button located
on the steering wheel.
4. Take your foot off the accelerator.
Resuming a Set Speed
Suppose you set your cruise control at a desired
speed and then you apply the brake. This
shuts off the cruise control. But you do not need
to reset it.
Once you are driving about 25 mph (40 km/h) or
more, press the +RES button on your steering
wheel. The vehicle will go back to the previously
chosen speed and stay there.
Increasing Speed While Using
Cruise Control
To increase the cruise speed while using cruise
control:
•
Press and hold the +RES button on the
steering wheel until you reach the desired
speed, then release it.
•
To increase vehicle speed in small increments,
press the +RES button.
