Remote Keyless Entry (RKE)
System
If the vehicle has the Remote Keyless Entry (RKE)
system, it operates on a radio frequency subject
to Federal Communications Commission (FCC)
Rules and with Industry Canada.
This device complies with Part 15 of the FCC
Rules. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.
This device complies with RSS-210 of Industry
Canada. Operation is subject to the following
two conditions:
1. This device may not cause interference.
2. This device must accept any interference
received, including interference that may
cause undesired operation of the device.Changes or modi cations to this system by other
than an authorized service facility could void
authorization to use this equipment.
At times you may notice a decrease in range. This
is normal for any RKE system. If the transmitter
does not work or if you have to stand closer
to your vehicle for the transmitter to work, try this:
Check the distance. You may be too far
from your vehicle. You may need to stand
closer during rainy or snowy weather.
Check the location. Other vehicles or objects
may be blocking the signal. Take a few steps
to the left or right, hold the transmitter
higher, and try again.
Check to determine if battery replacement is
necessary. See “Battery Replacement”
underRemote Keyless Entry (RKE) System
Operation on page 90.
If you are still having trouble, see your dealer
or a quali ed technician for service.

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is coded to
prevent another transmitter from unlocking your
vehicle. If a transmitter is lost or stolen, a
replacement can be purchased through your
dealer. Remember to bring any remaining
transmitters with you when you go to your dealer.
When the dealer matches the replacement
transmitter to your vehicle, any remaining
transmitters must also be matched. Once your
dealer has coded the new transmitter, the
lost transmitter will not unlock your vehicle. Each
vehicle can have a maximum of four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote
keyless entry transmitter should last about
three years.You can tell the battery is weak if the transmitter
will not work at the normal range in any location.
If you have to get close to your vehicle before
the transmitter works, it is probably time to change
the battery.
Notice:When replacing the battery, use care
not to touch any of the circuitry. Static
from your body transferred to these surfaces
may damage the transmitter.

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.

Brake Pedal Travel
See your dealer if the brake pedal does not return
to normal height, or if there is a rapid increase in
pedal travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you make a moderate brake stop,
the disc brakes adjust for wear. If you rarely
make a moderate or heavier stop, the brakes
might not adjust correctly. If you drive in that way,
then — very carefully — make a few moderate
brake stops about every 1,000 miles (1 600 km),
so the brakes will adjust properly.
Replacing Brake System Parts
The braking system on a vehicle is complex. Its
many parts have to be of top quality and work well
together if the vehicle is to have really good
braking. Your vehicle was designed and tested
with top-quality GM brake parts. When you replace
parts of the braking system — for example,
when the brake linings wear down and you need
new ones put in — be sure you get newapproved GM replacement parts. If you do not, the
brakes might not work properly. For example, if
someone puts in brake linings that are wrong
for your vehicle, the balance between the front and
rear brakes can change — for the worse. The
braking performance you have come to expect can
change in many other ways if someone puts in
the wrong replacement brake parts.
Battery
Your vehicle has a maintenance free battery.
When it is time for a new battery, get one that has
the replacement number shown on the original
battery’s label. We recommend an ACDelco
®
replacement battery. SeeEngine Compartment
Overview on page 282for battery location.
Warning:Battery posts, terminals, and related
accessories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harm. Wash
hands after handling.

4. Open the hoods and locate the batteries. Find
the positive (+) and negative (−) terminal
locations on each vehicle. SeeEngine
Compartment Overview on page 282for more
information on location.
{CAUTION:
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
{CAUTION:
Using a match near a battery can cause
battery gas to explode. People have been
hurt doing this, and some have been
blinded. Use a ashlight if you need
more light.
Be sure the battery has enough water.
You do not need to add water to the
battery installed in your new vehicle. But
if a battery has ller caps, be sure the
right amount of uid is there. If it is low,
add water to take care of that rst. If you
don’t, explosive gas could be present.
Battery uid contains acid that can burn
you. Do not get it on you. If you
accidentally get it in your eyes or on your
skin, ush the place with water and get
medical help immediately.
