Remote Keyless Entry
(RKE) System
The Remote Keyless Entry (RKE)
system 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.
If there is a decrease in the RKE
operating range, try this:
Check the distance. The
transmitter may be too far from
the vehicle. 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 the transmitter’s battery.

How OnStar Service Works
The OnStar system can record
and transmit vehicle information.
This information is automatically sent
to an OnStar Call Center when the
OnStar button is pressed, the
emergency button is pressed, or if
the airbags deploy. This information
usually includes the vehicle’s GPS
location and, in the event of a crash,
additional information regarding the
crash that the vehicle was involved
in (e.g. the direction from which
the vehicle was hit). When the
Virtual Advisor feature of OnStar
Hands-Free Calling is used, the
vehicle also sends OnStar the
vehicle’s GPS location so they can
provide services where it is located.
OnStar service cannot work unless
the 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 the vehicle is in
a place where the wireless serviceprovider 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.
Location information about the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The 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 at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.Your Responsibility
Increase the volume of the radio if
the OnStar advisor cannot be heard.
If the light next to the OnStar
buttons is red, the system may not
be functioning properly. Press
the OnStar button and request a
vehicle diagnostic. If the light
appears clear (no light is appearing),
your OnStar subscription has
expired and all services have been
deactivated. Press the OnStar
button to con rm that the OnStar
equipment is active.

If the low oil level light appears on

engine oil level right away. SeeLow
Oil Level Light on page 4-22.
Check the engine oil level regularly;
this is just a reminder.
Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel ll.
In order to get an accurate reading,
the oil must be warm and the
vehicle must be on level ground.The engine oil dipstick handle
is a yellow loop. SeeEngine
Compartment Overview on page 9-6
for the location of the engine oil
dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with
a paper towel or cloth, then push
it back in all the way. Remove
it again, keeping the tip down and
check the level.

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. The vehicle was
designed and tested with top-quality
brake parts. When parts of the
braking system are replaced — for
example, when the brake linings
wear down and new ones are
installed — be sure to get new
approved replacement parts. If this
is not done, the brakes might not
work properly. For example,
if someone puts in brake linings
that are wrong for the vehicle, the
balance between the front and
rear brakes can change — for the
worse. The braking performance
expected can change in many other
ways if the wrong replacement
brake parts are installed.
Battery
This vehicle has a maintenance free
battery. When it is time for a new
battery, see your dealer/retailer
for one that has the replacement
number shown on the original
battery’s label. SeeEngine
Compartment Overview on page 9-6
for 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.
Vehicle Storage
{CAUTION
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. SeeJump Starting
on page 9-69for tips on
working around a battery without
getting hurt.
Infrequent Usage: If the vehicle is
driven infrequently, remove the
black, negative (−) cable from the
battery. This helps keep the battery
from running down.
Extended Storage: For extended
storage of the vehicle, remove
the black, negative (−) cable from
the battery or use a battery
trickle charger. This helps maintain
the charge of the battery over
an extended period of time.

Notice:If you leave the radio or
other accessories on during
the jump starting procedure,
they could be damaged. The
repairs would not be covered by
the warranty. Always turn off
the radio and other accessories
when jump starting the vehicle.
3. Turn off the ignition on both
vehicles. Unplug unnecessary
accessories plugged into
the cigarette lighter or the
accessory power outlet. Turn off
the radio and all lamps that
are not needed. This will avoid
sparks and help save both
batteries. And it could save
the radio!4. Open the hoods and locate the
batteries. Find the positive (+)
and negative (−) terminal
locations on each vehicle. Your
vehicle’s positive (+) terminal
is identi ed by “+” sign on battery
case or terminal. SeeEngine
Compartment Overview on
page 9-6.
{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.
