battery CADILLAC XLR 2004 1.G Owner's Manual

LOW COOLANT:This message will appear when there
is a low level of engine coolant. Have the cooling
system serviced by a technician as soon as possible.
See
Engine Coolant on page 5-20.
LOW FUEL:This message will appear when the fuel
supply is less than 5 gallons (18.9 L) and the display is
turned off. A single chime will also sound when this
message is displayed.
LOW OIL LEVEL:For correct operation of the low oil
sensing system, your vehicle should be on a level
surface. A false LOW OIL LEVEL message may appear
if the vehicle is parked on a grade. The oil level
sensing system does not check for actual oil level if the
engine has been off for a short period of time, and
the oil level is never checked while the engine is
running. If the LOW OIL LEVEL message appears, and
your vehicle has been parked on level ground with
the engine off for at least 30 minutes, the oil level should
be checked by observing the oil dipstick. Prior to
checking the oil level, be sure the engine has been off
for a few minutes and your vehicle is on a level
surface. Then check the dipstick and add oil if
necessary. See
Engine Oil on page 5-13.LOW OIL PRESSURE:If this message appears while
the engine is running, stop the engine and do not
operate it until the cause of low oil pressure is corrected.
Severe damage to the engine can result. A multiple
chime will sound when this message is displayed.
LOW VOLTAGE:This message will appear when the
electrical system is charging less than 10 volts or if
the battery has been drained. If this message appears
immediately after starting, it is possible that the
generator can still recharge the battery. The battery
should recharge while driving but may take a few hours
to do so. Consider using an auxiliary charger (be
sure to follow the manufacturer's instructions) to boost
the battery after returning home or to a ®nal destination.
If this message appears while driving or after starting
your vehicle and stays on, have it checked immediately
to determine the cause of this problem. To help the
generator recharge the battery quickly, you can reduce
the load on the electrical system by turning off the
accessories. You can monitor battery voltage on the DIC
by pressing the INFO button. The normal range is
11.5 to 15.5 volts.
LOW WASHER FLUID:This message means that your
vehicle is low on windshield washer ¯uid. See
Windshield Washer Fluid on page 5-33.

Radio Reception
AM
The range for most AM stations is greater than for FM,
especially at night. The longer range can cause
station frequencies to interfere with each other. Static
can occur on AM stations caused by things like
storms and power lines. Try reducing the treble to
reduce this noise.
FM Stereo
FM stereo will give the best sound, but FM signals will
reach only about 10 to 40 miles (16 to 65 km). Tall
buildings or hills can interfere with FM signals, causing
the sound to fade in and out.
XMŸ Satellite Radio Service
XMŸ Satellite Radio Service gives digital radio
reception from coast to coast. Just as with FM, tall
buildings or hills can interfere with satellite radio signals,
causing the sound to fade in and out. The radio may
display NO XM SIGNAL to indicate interference.
Cellular Phone Usage
Cellular phone usage may cause interference with your
vehicle's radio. This interference may occur when
making or receiving phone calls, charging the phone's
battery, or simply having the phone on. This interference
is an increased level of static while listening to the
radio. If static is received while listening to the radio,
unplug the cellular phone and turn it off.
Care of Your CDs
Handle CDs carefully. Store them in their original cases
or other protective cases and away from direct
sunlight and dust. If the surface of a CD is soiled,
dampen a clean, soft cloth in a mild, neutral detergent
solution and clean it, wiping from the center to the edge.
Be sure never to touch the side without writing when
handling CDs. Pick up CDs by grasping the outer edges
or the edge of the hole and the outer edge.
Care of Your CD Player
The use of CD lens cleaners for CD players is not
advised, due to the risk of contaminating the lens of the
CD optics with lubricants internal to the CD mechanism.
3-72

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.
Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine
again and repeat this only when you feel really
uncomfortable from the cold. But do it as little as
possible. Preserve the fuel as long as you can. To help
keep warm, you can get out of the vehicle and do
some fairly vigorous exercises every half hour or so until
help comes.
If You Are Stuck: In Sand, Mud, Ice
or Snow
In order to free your vehicle when it is stuck, you will
need to spin the wheels, but you do not want to
spin your wheels too fast. The method known as
ªrockingº can help you get out when you are stuck, but
you must use caution.
{CAUTION:
If you let your tires spin at high speed, they
can explode, and you or others could be
injured. And, the transmission or other parts of
the vehicle can overheat. That could cause an
engine compartment ®re or other damage.
When you are stuck, spin the wheels as little
as possible. Do not spin the wheels above
35 mph (55 km/h) as shown on the
speedometer.
Notice:Spinning your wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting your transmission
back and forth, you can destroy your transmission.
For information about using tire chains on your
vehicle, see
Tire Chains on page 5-68.

Engine Oil
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 ªLOW OIL LEVELº and
ªLOW OIL PRESSUREº under
DIC Warnings and
Messages on page 3-57.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 5-12for
the location of the engine oil dipstick.
Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil
dipstick might not show the actual level.
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 new vehicle comes with a maintenance free
ACDelcožbattery. 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
ž
battery.
For battery replacement, see your dealer or the service
manual. To purchase a service manual, see
Service
and Owner PublicationsinService Publications Ordering
Information on page 7-11.
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. See
Jump Starting on
page 5-39
for 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 key FOB.
Failure to follow this procedure may result in a sounding
alarm. Pressing unlock on the key FOB would stop
the sounding alarm.
Contact your dealer to learn how to prepare your
vehicle for longer storage periods.
Also, for your audio system, see
Theft-Deterrent
Feature on page 3-71.
5-38

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 follow the steps below 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 brakes.
5-39

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 in 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 your radio!
4. Open the hoods and locate the batteries. Find the
positive (+) and negative (-) terminal locations on
each vehicle. See
Engine Compartment Overview
on page 5-12for 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 ACDelco
žbattery
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.
5-40

{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.
