2005 CHEVROLET COBALT battery replacement

Changes or modications 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 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” under
Remote Keyless Entry System Operation on
page 2-4.
If you are still having trouble, see your dealer or a
qualied technician for service.
Remote Keyless Entry System
Operation
If your vehicle has this feature, the vehicle’s doors can
be locked and unlocked, and the trunk can be
unlocked from about 3 feet (1 m) up to 60 feet (18 m)
away with the remote keyless entry transmitter.
If you notice a decrease in the operating range of the
transmitter, seeRemote Keyless Entry System on
page 2-3for information regarding conditions which may
affect the transmitter’s performance.
The following functions are
available with the remote
keyless entry system.
2-4

Matching Transmitter(s) to Your
Vehicle
Each remote keyless entry transmitter is uniquely coded
to prevent another transmitter from unlocking the
vehicle. If a transmitter is lost or stolen, a replacement
can be purchased through your GM dealer. Remember
to bring any additional transmitters with you when
you go to your dealer. The vehicle can have a maximum
of four transmitters matched to it.
Battery Replacement
Under normal use, the battery in the remote keyless
entry transmitter should last about four 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. The
KEY FOB BATT LOW message in the vehicle’s DIC will
display, if the remote keyless entry transmitter battery
is low.
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 do the following:
1. Insert a at object with a thin edge into the notch,
located below the Vehicle Locator/Panic Alarm
button, and pry the front and back apart.
2. Remove the old battery, but do not use a metal
object to do this.
3. Slide the new battery into the transmitter with the
positive side of the battery facing up. Use a type
CR2032 battery, or equivalent type.
4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.

Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear. If you rarely make a moderate
or heavier stop, then your 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 your brakes will adjust
properly.
If you have rear drum brakes and your brake pedal
goes down farther than normal, the rear drum brakes
may need adjustment. Adjust them by backing up
and rmly applying the brakes a few times.
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 your braking
system — for example, when your brake linings
wear down and you need new ones put in — be sure
you get new approved GM replacement parts.If you do not, your brakes may no longer work properly.
For example, if someone puts in brake linings that
are wrong for your vehicle, the balance between your
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.
Your vehicle’s battery is located in the trunk. You do not
need to access the battery to jump start your vehicle.
SeeJump Starting on page 5-40.
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.
