OnStar service that involves location information about
your vehicle cannot work unless GPS satellite signals
are unobstructed and available in that place as well.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
You may need to increase the volume of your radio
to hear the OnStar advisor. If the light next to the
OnStar buttons is red, this means that your system is
not functioning properly and should be checked by your
dealer/retailer. If the light appears clear (no light is
appearing), your OnStar subscription has expired.
You can always press the OnStar button to conrm
that your OnStar equipment is active.

button located on
the console behind
the shifter lever.
The windows will automatically lower and the top will
automatically lower into the storage area. A chime
will sound when the top has lowered completely.
If the radio is on, the sound may be muted briey while
the retractable top is lowered. This occurs because
a new audio system equalization is being loaded.
Under certain conditions, the Driver Information Center
(DIC) may display messages regarding the retractable
hardtop. SeeDIC Warnings and Messages on
page 3-63for more information.
If the retractable hardtop does not operate, and there
are no messages displayed on the Driver Information
Center (DIC), then perform the “Power Window Initialize”

equalization being loaded for the vehicle with the
top raised.
Under certain conditions, the Driver Information
Center (DIC) may display messages regarding the
retractable hardtop. SeeDIC Warnings and Messages
on page 3-63for more information.
If the retractable hardtop does not operate, and there
are no messages displayed on the Driver Information
Center (DIC), then perform the “Power Window Initialize”
steps underPower Windows on page 2-17.Manually Raising the Retractable Hardtop
If your vehicle has a power loss, such as a dead battery,
you can still raise the top manually by doing the following:
1. Lower both sun visors and open both doors.

Using Cruise Control on Hills
How well your cruise control works on hills depends upon
your speed, load and the steepness of the hills. When
going up steep hills, you might have to step on the
accelerator pedal to maintain your speed. When going
downhill, you might have to brake or shift to a lower gear
to keep your vehicle’s speed down. Of course, applying
the brake turns off the cruise control. Many drivers nd
this to be too much trouble and do not 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
Turning off the cruise control or the ignition, will erase
your cruise control set speed memory.
