2007 CADILLAC CTS V battery location

At times you may notice a decrease in operating
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 97.
If you are still having trouble, see your
dealer/retailer or a qualied technician
for service.
Remote Keyless Entry (RKE)
System Operation
With this feature, you can lock and unlock the
doors or the trunk and turn on your vehicle’s
interior lamps from about 10 feet (3 m) away using
the Remote Keyless Entry (RKE) transmitter
supplied with your vehicle.
Q(Lock):Press this
symbol on the RKE
transmitter to lock
the doors. This also
arms the theft-deterrent
system.
You can program your vehicle so that the exterior
lamps will ash and/or the horn will sound
when you lock the doors with the RKE transmitter.
SeeDIC Vehicle Personalization on page 242
for more information on programming this feature.

Battery Replacement
Under normal use, the battery in the RKE
transmitter should last about four years.
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.
1. Use a at thin object to pry open the
transmitter.
2. Remove the old battery, but do not use a
metal object.3. Insert the new battery as the instructions
under the cover indicate.
4. Snap the front and the back of the transmitter
together. Make sure the cover is on tightly,
so water will not get in.
5. Press any button on the RKE transmitter to
resynchronize the transmitter.
6. Test the operation of the transmitter with
the vehicle.

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 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 conrm that your OnStar®
equipment is active.

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 342for 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.
{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 376for tips on working
around a battery without getting hurt.
After a power loss, such as disconnecting the
battery or removing the maxi fuses in the power
distribution fuse block, the following steps must be
performed to calibrate the electronic throttle control.
If this is not done, the engine will not run properly.
1. Turn the ignition key to ON. Do not start the
engine.
2. Leave the ignition in ON for at least
three minutes so that the electronic throttle
control will cycle and re-learn its home
position.
3. Turn the ignition to OFF.
4. Start and run the engine for at least
30 seconds.
375

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
outlets. 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 positive (+)
and negative (−) terminal locations of the
other vehicle, as well as the positive (+)
terminal location on your vehicle’s battery.
SeeEngine Compartment Overview on
page 342for more information on the location
of the battery.
377

Your vehicle has a remote negative (−) ground
location, as shown in the illustration. It is
located between the battery and the
underhood fuse block. You should always use
this remote ground location, instead of the
terminal on the battery.Notice:If you connect a negative cable to the
ECM engine control module, ECM mounting
bracket, or any cables that attach to the
ECM bracket, you may damage the ECM.
Always attach the negative cable to your
vehicle’s remote negative ground location,
instead of the ECM, ECM bracket, or any cables
attached to the ECM bracket.
{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.

6. Connect the red positive (+) cable to the
positive (+) terminal of the dead battery.
Use a remote positive (+) terminal if
the vehicle has one.
7. Do not let the other end touch metal. Connect
it to the positive (+) terminal of the good
battery. Use a remote positive (+) terminal if
the vehicle has one.
8. Now connect the black negative (−) cable to
the negative terminal of the good battery. Use
a remote negative (−) terminal if the vehicle
has one.Do not let the other end touch anything until the
next step. The other end of the negative (−)
cable does not go to the dead battery. It goes to
a heavy, unpainted metal engine part or to a
remote negative (−) terminal on the vehicle with
the dead battery.
9. Connect the other end of the negative (−) cable
at least 18 inches (45 cm) away from the dead
battery, but not near engine parts that move.
The electrical connection is just as good there,
and the chance of sparks getting back to the
battery is much less.
Use a remote negative (−) terminal if the
vehicle has one. Your vehicle’s remote
negative (−) ground location is for this
purpose.
10. Now start the vehicle with the good battery
and run the engine for a while.
11. Try to start the vehicle that had the dead
battery. If it will not start after a few tries, it
probably needs service.
