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 four ways to turn off the cruise control:
•
Step lightly on the brake pedal,
•
move the cruise control switch to off, or
•
shift the transmission to NEUTRAL (N).
•
If your vehicle has the Stabilitrak
®
feature, cruise
control will turn off if road conditions cause
Stabilitrak
®
to activate.
•
If the accelerator pedal is held for 60 seconds or
longer, cruise control will turn off.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Headlamps
The control on the driver’s side of your instrument panel
operates the headlamps.
Turn the control clockwise to operate the lamps.
The headlamp control has four positions:
9
(Off): Turning the control to this position turns off
the Daytime Running Lamps (DRL) and the automatic
headlamps.
AUTO (Automatic): Turning the control to this position
puts the system into automatic headlamp mode.
