At times you may notice a decrease in range. This
is normal for any remote keyless entry 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 retailer
or a quali ed technician for service.
Remote Keyless Entry (RKE)
System Operation
The vehicle’s doors can be locked and unlocked,
and the trunk can be opened from about 3 feet
(1 m) up to 197 feet (60 m) away with the Remote
Keyless Entry (RKE) transmitter.
Use the following
functions if your vehicle
has the RKE system.

Matching Transmitter(s) to Your
Vehicle
Each RKE 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 retailer. Remember to
bring any remaining transmitters with you
when you go to your retailer. Each vehicle can
have a maximum of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in your RKE
transmitter should last about four years.
The battery is weak if the transmitter does 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.
If the battery is low, a KEY FOB BATT (Battery)
LOW message will display in the vehicle’s DIC.
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.To replace the battery in the RKE transmitter do
the following:
1. Insert a at object, with a thin edge, into the
notch located below the vehicle locator/panic
alarm button, and separate the bottom
half from the top half of the transmitter.
2. Remove the battery and replace it with the
new one. Make sure the positive (+) side of
the battery faces up. Use one three-volt,
CR2032, or equivalent, type battery.

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 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 con rm that your OnStar®

Checking Engine Oil
It is a good idea to check the engine oil every time
you get fuel. 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 264
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 you
do not do this, the oil dipstick might not
show the actual level.
2. Pull out 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.

Notice:If you leave your radio or other
accessories on during the jump starting
procedure, they could be damaged. The repairs
would not be covered by your warranty.
Always turn off your radio and other
accessories when jump starting your 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 located under a
red tethered cap on the battery. The
negative (–) terminal is located under a black
tethered cap on the battery. SeeEngine
Compartment Overview on page 264for more
information on location. Flip the caps up to
access the positive (+) and negative (–)
terminals.
{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.
