2005 CADILLAC XLR battery

Radio Personalization with Home
and Away Feature
With this feature, you can recall the latest audio system
settings as adjusted the last time your vehicle was
operated. This feature allows two different drivers to store
and recall their own audio system settings. The settings
recalled by the audio system are determined by which
RKE transmitter (1 or 2) was used to enter the vehicle.
The number on the back of the RKE transmitter
corresponds to driver 1 or to driver 2. The audio system
settings will automatically adjust to where they were last
set by the identied driver. The settings can also be
recalled by briey pressing the MEMORY seat switches 1
or 2 located on the driver’s door.
Your audio system can store HOME and AWAY preset
stations. HOME and AWAY preset stations allow
you to use one set of preset radio settings in the area
where you live, and another set when you go out of
town. That way, you will not need to reprogram
your preset stations every time you travel.To select HOME and AWAY preset stations, do the
following:
1. With the audio system on, touch the Audio hard key
and turn the audio system off.
2. Touch the HOME or AWAY button from the main
audio screen.
The next time the audio system is turned on, the
system will recall the last active preset selection.
When battery power is removed and later applied, you
will not have to reset your home audio system preset
stations because the audio system remembers
them. However, you will have to reset your away radio
preset stations.
Voice Recognition
The navigation system’s voice recognition allows for
hands-free operation of navigation and audio system
features. Voice recognition can be used when the ignition
is in on or when Retained Accessory Power (RAP)
is active.
This feature only works if the map DVD is inserted and
I AGREE has been selected. If you try to use voice
recognition without the map DVD inserted, the system
will display “Please insert the navigation map DVD
to use the voice recognition feature.”

You can run the engine to keep warm, but be careful.
{CAUTION:
Snow can trap exhaust gases under your
vehicle. This can cause deadly CO (carbon
monoxide) gas to get inside. CO could
overcome you and kill you. You cannot see it
or smell it, so you might not know it is in your
vehicle. Clear away snow from around the
base of your vehicle, especially any that is
blocking your exhaust pipe. And check around
again from time to time to be sure snow does
not collect there.
Open a window just a little on the side of the
vehicle that is away from the wind. This will
help keep CO out.
Run your engine only as long as you must. This saves
fuel. When you run the engine, make it go a little
faster than just idle. That is, push the accelerator
slightly. This uses less fuel for the heat that you get and
it keeps the battery charged. You will need a
well-charged battery to restart the vehicle, and possibly
for signaling later on with your headlamps. Let the
heater run for a while.

If the LOW OIL LEVEL or LOW OIL PRESSURE
message on the Driver Information Center appears, it
means you need to check your engine oil level right
away. For more information, see LOW OIL LEVEL and
LOW OIL PRESSURE underDIC Warnings and
Messages on page 3-64.
You should check your engine oil level regularly; this is
an added reminder.
Checking Engine Oil
It is a good idea to check your 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. See
Engine Compartment Overview on page 6-12for
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.

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.
For battery replacement, see your dealer or the service
manual. To purchase a service manual, seeService
and Owner PublicationsinService Publications Ordering
Information on page 8-12.
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
If you are not going to drive your vehicle for 25 days or
more, remove the black, negative (−) cable from the
battery. This will help keep your battery from
running down.
{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 6-37for tips on working around a battery
without getting hurt.
You must close all doors and the trunk before
reconnecting the battery. After reconnecting the battery,
you must press the unlock button on the keyless
access transmitter. Failure to follow this procedure may
result in the alarm sounding. Pressing unlock on the
keyless access transmitter would stop the alarm.
Also, for your audio system, seeTheft-Deterrent Feature
on page 3-78.

Jump Starting
If your battery has run down, you may want to use
another vehicle and some jumper cables to start your
vehicle. Be sure to use the following steps to do it safely.
{CAUTION:
Batteries can hurt you. They can be dangerous
because:
They contain acid that can burn you.
They contain gas that can explode or ignite.
They contain enough electricity to
burn you.
If you do not follow these steps exactly, some or
all of these things can hurt you.
Notice:If you try to start your vehicle by pushing
or pulling it, you could damage your vehicle. Do not
push or pull your vehicle to start it; instead, use
the jump starting procedure in this manual to start
your vehicle when the battery has run down.
1. Check the other vehicle. It must have a 12-volt
battery with a negative ground system.Notice:If the other vehicle’s system is not a 12-volt
system with a negative ground, both vehicles can
be damaged. Only use vehicles with 12-volt systems
with negative grounds to jump start your vehicle.
2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles are not touching
each other. If they are, it could cause a ground
connection you do not want. You would not be able
to start your vehicle, and the bad grounding
could damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake rmly on both vehicles involved
in the jump start procedure. Put an automatic
transmission in PARK (P) or a manual transmission
in NEUTRAL before setting the parking brake.
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. SeeEngine Compartment Overview
on page 6-12for more information on location.
{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 do not, 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.
6-38

{CAUTION:
Fans or other moving engine parts can injure
you badly. Keep your hands away from moving
parts once the engine is running.
5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive (+) terminal if
the vehicle has one. Negative (−) will go to a heavy,
unpainted metal engine part or to a remote
negative (−) terminal if the vehicle has one.
Do not connect positive (+) to negative (−)oryou
will get a short that would damage the battery
and maybe other parts too. And do not connect the
negative (−) cable to the negative (−) terminal on
the dead battery because this can cause sparks.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.
