2004 CADILLAC DEVILLE check engine light

BATTERY VOLTAGE LOW – 6: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.
CHANGE ENGINE OIL – 82:This means that the life
of the engine oil has expired. SeeScheduled
Maintenance on page 6-4. After an oil change, the Oil
Life Indicator must be reset. SeeOil Life Indicator
on page 3-89. SeeEngine Oil on page 5-15.CHANGE TRANS FLUID – 47:This message will
appear when it is time to change the transaxle uid. See
Scheduled Maintenance on page 6-4for the proper
uid and change intervals.
CHECK BRAKE FLUID – 37:This message will display
if the ignition is in ON to inform the driver that the brake
uid level is low. Have the brake system serviced by a
technician as soon as possible. SeeBrake System
Warning and Parking Brake Indicator Light on page 3-51.
CHECK COOLANT LEVEL – 2: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. SeeEngine Coolant on page 5-27.
CHECK FUEL GAGE – 50:(Analog Cluster) 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.
CHECK GAS CAP – 61:This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it is on properly.

Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is
a mistake. Your brakes may not have time to cool
between hard stops. Your brakes will wear out much
faster if you do a lot of heavy braking. If you keep pace
with the traffic and allow realistic following distances,
you will eliminate a lot of unnecessary braking.
That means better braking and longer brake life.
If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.Anti-lock Brake System (ABS)
Your vehicle has anti-lock brakes. ABS is an advanced
electronic braking system that will help prevent a
braking skid.
When you start your engine and begin to drive away,
your anti-lock brake system will check itself. You
may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that your
brake pedal moves a little. This is normal.
If there is a problem with
the anti-lock brake system,
this warning light will
stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-52.

Here are some things to do to summon help and keep
yourself and your passengers safe:
Turn on your hazard ashers.
Tie a red cloth to your vehicle to alert police that
you have been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make
body insulators from newspapers, burlap bags, rags,
oor mats — anything you can wrap around
yourself or tuck under your clothing to keep warm.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 can not 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.

How to Reset the Transaxle Fluid
Indicator
After the transaxle uid has been changed, the transaxle
uid change indicator must be reset. To reset the
indicator, do the following:
1. Press the INFO button on the Driver Information
Center (DIC) until TRANS FLUID LIFE is displayed.
2. Press and hold the RESET button until 100%
is displayed. This resets the transaxle uid change
indicator.
The percentage of transaxle uid life remaining may be
checked at any time by pressing the INFO on the
DIC until the TRANS FLUID LIFE message appears.
Engine Coolant
The cooling system in your vehicle is lled with
DEX-COOL®engine coolant. This coolant is designed
to remain in your vehicle for 5 years or 150,000 miles
(240 000 km), whichever occurs rst, if you add
only DEX-COOL
®extended life coolant.The following explains your cooling system and how to
add coolant when it is low. If you have a problem with
engine overheating, seeEngine Overheating on
page 5-31.
A 50/50 mixture of clean, drinkable water and
DEX-COOL
®coolant will:
Giving freezing protection down to−34° F−37° C.
Give boiling protection up to 265° F (129° C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as they
should.
Notice:Using coolant other than DEX-COOL
®may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs rst. Any repairs
would not be covered by your warranty. Always use
DEX-COOL
®(silicate-free) coolant in your vehicle.
