battery CADILLAC CTS V 2006 1.G User Guide

Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.
Oil Pressure Light
{CAUTION:
Do not keep driving if the oil pressure is low.
If you do, your engine can become so hot that
it catches re. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.Notice:Lack of proper engine oil maintenance may
damage the engine. The repairs would not be
covered by your warranty. Always follow the
maintenance schedule in this manual for changing
engine oil.
If your vehicle has this
light, it will come on when
there is a problem with
your engine oil pressure.
This light will come on when you turn your key to ON or
START. It goes off once you start the engine. That is a
check to be sure the light works. If it does not come on,
be sure to have it xed so it will be there to warn you if
there is a problem.
When the light comes on and stays on, it means that oil is
not owing through your engine properly. You could be
low on oil and you might have some other system
problem. SeeEngine Oil on page 5-16for more
information.

voltage on the DIC by pressing the INFO button
until BATTERY VOLTS appears.
3-61

Battery Voltage Low
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 the
engine, 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 to boost the battery after returning
home or to a nal destination. Make sure you follow
the manufacturer’s instructions.
If this message appears while driving or after starting
your vehicle and stays on, have it checked by your
GM dealer 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.

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. For
better radio reception, most AM radio stations will boost
the power levels during the day, and then reduce
these levels during the night. Static can also occur when
things like storms and power lines interfere with radio
reception. When this happens, try reducing the treble on
your radio.
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.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada (if available). Just as with
FM, tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy foliage,
bridges, garages, or tunnels may cause loss of XM
signal for a period of time. 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. The CD player scans the bottom
surface of the disc. If the surface of a CD is damaged,
such as cracked, broken, or scratched, the CD will
not play properly or not at all. If the surface of a CD is
soiled, take a soft, lint free cloth or dampen a clean, soft
cloth in a mild, neutral detergent solution mixed with
water, and clean it. Make sure the wiping process starts
from the center to the edge.
Do not touch the bottom side of a CD while handling it;
this could damage the surface. Pick up CDs by
grasping the outer edges or the edge of the hole
and the outer edge.
3-103

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 Your Vehicle is 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
rocking can help you get out when you are stuck,
but you must use caution.
{CAUTION:
If you let your vehicle’s 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 the wheels can destroy parts of
your vehicle as well as the tires. If you spin the
wheels too fast while shifting the transmission back
and forth, you can destroy the transmission.
For information about using tire chains on your vehicle,
seeTire Chains on page 5-78.
