How OnStar®Service Works
In order to provide you with OnStar®services, your
vehicle’s OnStar®system has the capability of
recording and transmitting vehicle information.
This information is automatically sent to an OnStar
®
Call Center at the time of an OnStar®button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually
includes your GPS location and, in the event of a
crash, additional information regarding the accident
that your vehicle has been involved in (e.g. the
direction from which your vehicle was hit). When
you use the Virtual Advisor feature of OnStar
®
Hands-Free Calling, your vehicle also sends
OnStar®your GPS location so that we can provide
you with location-based services.
OnStar
®service cannot work unless your vehicle
is in a place where OnStar®has an agreement
with a wireless service provider for service in that
area. OnStar
®service also cannot work unless
you are in a place where the wireless service
provider OnStar
®has hired for that area
has coverage, network capacity and reception
when the service is needed, and technology that
is compatible with the OnStar
®service. Not all
services are available everywhere, particularly in
remote or enclosed areas, or at all times.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 a dealer. If the light appears
clear (no light is appearing), your OnStar
®
subscription has expired. You can always press
the blue OnStar®button to con rm that your
OnStar®equipment is active.

If the tow vehicle will not be started or driven
for six weeks or more, remove the battery
cable from the negative terminal (post) of the
battery to prevent your battery from draining
while towing.
After towing, see “Shifting Out of NEUTRAL”
underFour-Wheel Drive on page 126.
Towing a Trailer
{CAUTION:
If you do not use the correct equipment
and drive properly, you can lose control
when you pull a trailer. For example, if the
trailer is too heavy, the brakes may not
work well — or even at all. You and your
passengers could be seriously injured.
Pull a trailer only if you have followed all
the steps in this section. Ask your dealer
for advice and information about towing
a trailer with your vehicle.Notice:Pulling a trailer improperly can
damage your vehicle and result in costly
repairs that would not be covered by your
warranty. Always follow the instructions in this
section and check with your dealer for more
information about towing a trailer with
your vehicle.
To identify the trailering capacity of your vehicle,
you should read the information in “Weight of
the Trailer” that appears later in this section.
Trailering is different than just driving your vehicle
by itself. Trailering means changes in handling,
acceleration, braking, durability and fuel economy.
Successful, safe trailering takes correct
equipment, and it has to be used properly.
That’s the reason for this part. In it are many
time-tested, important trailering tips and safety
rules. Many of these are important for your safety
and that of your passengers. So please read
this section carefully before you pull a trailer.
