This message shows that the electrical charging system is overcharging,
(more than 16 volts). To avoid being stranded have the electrical system
checked by your Cadillac dealership at your earliest convenience. You can
reduce the charging overload
by using the accessories. Turn on the lights,
radio, set the Climate Control on
“AUTO” and the fan speed on “HI”
and turn the rear window defogger on. You can monitor battery voltage
on the Driver Information Center by toggling the “INFORMATION”
button. When the engine is running, the normal range
is 11.5 to 15.5
volts.
c
BATTERY VOLTS 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 it is possible that the generator can still
recharge the battery. The battery should recharge after driving a few
miles and the message should go out. 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 your accessories. You can monitor battery
voltage on the Driver Information Center by toggling the
“INFORMATION’’ button. The normal range is
11.5 to 15.5 volts.
CHANGE TRANS FLUID (Northstar Only)
This message will appear when it is time to replace the transaxle fluid.
See your maintenance booklet
for the proper fluid and change intervals.
CHECK BRAKE FLUID
This message is displayed to inform the driver that the brake reservoir
fluid level is low. Check the brake reservoir level and add as needed.
Have the brake system serviced by a Cadillac technician as soon as
possible.
If the brake warning light is on, follow the directions in that
section.
CHECK COOLANT LEVEL (Northstar Only)
This message will appear when there is a low level of engine coolant.
Have the cooling system serviced by a Cadillac technician as soon as
possible.

This message will appear when your fuel supply is less than 4 gallons and
your display
is turned off.
CHECK OIL LEVEL (Northstar Only)
This message will appear when your engine oil is approximately a quart
low. If this message is displayed, check the
oil and add as needed.
CHANGE OIL SOON
This message will appear when your engine oil is less than 10 percent or
the mileage since
the last oil change is more than 6750 miles.
CHANGE ENGINE OIL
This means that the life of your engine oil has expired and it should be
changed immediately. See engine oil and filter recommendations
in the
Maintenance Schedule. After an oil change, the Oil Life Index must be
reset. See “Oil Life Indicator”
in the index on how to reset it.
ENGINE COOLANT HOT IDLE ENGINE
This message will appear when your engine coolant temperature is over
126°C (248°F). To avoid added strain on a hot engine, turn off your
Climate Control system and stop and allow your vehicle to idle until
it
cools down or the message is removed. If it does not cool down, turn off
your engine and have it serviced before driving it again. Severe engine
damage can result from an overheated engine. See “Engine Overheating”
in the Index.
ENGINE HOT - A/C COMPRESSOR OFF
This message will appear when the Climate Control is in “Auto” or
Defrost and the engine coolant is hotter than
the normal operating
temperature. To avoid added strain on a hot engine the air conditioning
compressor is automatically turned
off. When that happens, air
conditioned air
is not delivered. If the coolant temperature returns to
normal, you must select
“AUTO”, “DEFOG” or Defrost to return to a
normal A/C compressor operation.
FUEL LEVEL VERY LOW
This message serves as a warning that the fuel level in your tank is
critically low. It means you shwld stop for fuel immediately.

yours a little uphill to take some of the pressure from the transaxle, so
you can pull the shift lever out of “P” (Park).
‘WINTER DmNG
V
Here are some tips for winter driving:
0 Have your Cadillac in good shape for winter. Be sure your engine
coolant
mix is correct.
Snow tires can help in loose snow, but they may give you less traction
on ice than regular tires.
If you do not expect to be driving in deep
snow,
but may have to travel over ice, you may not want to switch to
snow tires at all.
You may want to put winter emergency supplies in your trunk.

You will find the warning light about a hot engine on your Cadillac
instrument panel (Export
Only).
The driver information will display either “ENGINE COOLANT HOT
IDLE ENGINE” or “STOP ENGINE ENGINE OVERHEATING.”
If Steam Is Coming From Your Engine:
A CAUTION
Steam from an overheated engine can burn you badly, even if
you just open the hood. Stay
away from the engine if you see or
hear steam coming from it. Just turn it off and get everyone
away from the vehicle until
it cools down. Wait until there is no
sign of steam or coolant before opening the hood.
If you keep driving when your engine is overheated, the liquids
in it can catch fire. You or others could be badly burned. Stop
your engine
if it overheats, and get out of the vehicle until the
engine
is cool.

When you decide it's safe to lift the hood, here's what you'll see:
v Coolant recovery tank
v Radiator pressure cap
Electric engine fans
1 A CAUTION:
An electric fan under the hood 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,
If the coolant inside the coolant recovery tank is boiling, don't do
anything else until
it cools down.

Downloaded from www.Manualslib.com manuals search engine The coolant level should be at or above “FULL COLD.” If it isn’t, you
may have a
leak in the radiator hoses, heater hoses, radiator, water pump
or somewhere else
in the cooling system.
I
A CAUTION
Heater and radiator hoses, and other engine parts, can be very
hot. Don’t touch them.
If you do, you can be burned.
Don’t run the engine
if there is a leak. If you run the engine, it
could lose all coolant. That could cause an engine fire, and you
could be burned. Get any leak
fixed before you drive the vehicle.
If there seems to be no leak, check to see if the electric engine fans are
running.
If the engine is overheating, both fans should be running. If they
aren’t, your vehicle needs service.

How to Add Coolant to the Coolant Recovery Tank
If you haven’t found a problem yet, but the coolant level isn’t at or above
“FULL COLD,” add a 50/50 mixture of clean water (preferably distilled)
and
a proper antifreeze at the coolant recovery tank. (See “Engine
Coolant” in the Index for more information about the proper coolant
mix.)
A CAUTION
Adding only plain water to your cooling system can be
dangerous. Plain water, or some other liquid like alcohol, can
boil before the proper coolant
mix will. Your vehicle’s coolant
warning system is set for the proper coolant
mix. With plain
I water or the wrong mix, your engine could get too hot but you
~ wouldn’t get the overheat warning. Your engine could catch fire
~ and you or others could be burned. Use a 50/50 mix of clean
~ water and a proper antifreeze.
