2002 Oldsmobile Bravada change key battery

2-11
Changes or modifications 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 or
resynchronization is necessary. See the instructions
that follow.

If you're still having trouble, see your dealer or a
qualified technician for service.Operation
(Unlock): When you
press unlock, the driver's
door will unlock
automatically, the parking
lamps may flash and the
interior lights will go on.
You can program different feedback settings through the
Driver Information Center (DIC). For more information
see ªDriver Information Center (DIC)º in the Index.
(Lock): Press lock to lock all the doors. Press lock
again within three seconds and the horn may chirp.
(Panic): When the button with the horn symbol
on the key transmitter is pressed, the horn will sound
and the headlamps and taillamps will flash for up to
30 seconds. This can be turned off by pressing the horn
button again, or by waiting for 30 seconds, or by starting
the vehicle.

2-12 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 only four transmitters
matched to it.
Battery Replacement
Under normal use, the battery in your remote keyless
entry transmitter should last about two years.
You can tell the battery is weak if the transmitter won't
work at the normal range in any location. If you have to
get close to your vehicle before the transmitter works,
it's probably time to change the battery.
The Driver Information Center (DIC) will display a
RFA # BATTERY LOW message when the 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.

1. With your foot off the accelerator pedal, turn the
ignition key to START. When the engine starts,
let go of the key. The idle speed will go down as
your engine gets warm.
NOTICE:
Holding your key in START for longer than
15 seconds at a time will cause your battery to
be drained much sooner. And the excessive heat
can damage your starter motor. At 15 seconds,
the starter will automatically be disengaged.
Wait about 15 seconds between each try to
help avoid draining your battery or damaging
your starter.
2. If it doesn't start within 10 seconds, push the
accelerator pedal all the way to the floor, while you
hold the ignition key in START. When the engine
starts, let go of the key and let up on the accelerator
pedal. Wait about 15 seconds between each try.When starting your engine in very cold weather
(below 0
F or
-18
C), do this:
1. With your foot off the accelerator pedal, turn the
ignition key to START and hold it there. When the
engine starts, let go of the key.
2. If your engine still won't start (or starts but then
stops), it could be flooded with too much gasoline.
Try pushing your accelerator pedal all the way to
the floor and holding it there as you hold the key
in START for about three seconds. When the
engine starts, let go of the key and accelerator.
If the vehicle starts briefly but then stops again,
do the same thing, but this time keep the pedal down
for five or six seconds. This clears the extra gasoline
from the engine.
NOTICE:
Your engine is designed to work with the
electronics in your vehicle. If you add electrical
parts or accessories, you could change the way
the engine operates. Before adding electrical
equipment, check with your dealer. If you don't,
your engine might not perform properly.
