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 - 04
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.
CHECK FUEL GAGE - 39
This message will appear when your fuel supply is less than 4 gallons and
your display
is turned off.

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 - 82
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

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 - 16
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 - 11
This message serves as a warning that the fuel level in your tank is
critically low.
It means you should stop for fuel immediately.
SERVICE A/C SYSTEM A/C COMPRESSOR OFF - 14
This message appears when the electronic sensors that control the A/C
and heating system are no longer working.
You may notice a drop in
heating and A/C efficiency when this message appears. Have your
Climate Control system serviced if this message appears.

IGNITION
KEY - 33
This message will appear when the Personalized Automotive Security
System
(PASS Key II@) senses that an improper ignition key is being used
to try to start the vehicle. Check the ignition key
for damage. If it is
damaged, it may need to be replaced. If you see no damage, clean the
pellet contacts with a soft cloth or napkin. Remove the ignition key and
wait for the Driver Information Center to display “WAIT
3 MINUTES”.
The Instrument Panel Cluster will then run a timer and change the
messages to “WAIT
2 MINUTES”, “WAIT 1 MINUTE”, and then
“START CAR”. When the “START CAR” message is displayed, try again
to start the engine.

The coolant level should be visible inside the surge tank. If it isn’t and the
“ENGINE COOLANT LOW” message appears on the Driver
Information Center, you may have a coolant leak somewhere in the
cooling system. Should a low coolant condition exist, an overheat

Engine damage from running your engine without coolant isn’t
covered
by your warranty.
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 Surge Tank
If you haven’t found a problem yet, but the coolant level isn’t visible
inside the surge tank add a
50/50 mixture of clean water (preferably
distilled) and a proper antifreeze at the coolant surge tank, but be sure
the cooling system, including the coolant surge tank pressure cap, is cool
before you do it.
(See “Engine Coolant” in the Index for more
information about the proper coolant mix.)
If it isn’t, you may have a leak in the radiator fiose, heater hoses, radiator, -
water pump or somewhere else in the cooling system. -

pressure cap. Be
sure the arrows on
the pressure cap
line up
like this.
Start the engine and allow it to warm up. If the “ENGINE COOLANT
LOW” message does not appear on the Driver Information Center,
coolant is at the proper fill level. If an “ENGINE COOLANT
LOW”
message does appear, repeat steps 1 to 3 or see your dealer.
IF A TIRE GOES FLAT
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out of a tire, it’s much more likely
to leak out slowly. But
if you should ever have a “blowout,” here are a
few tips about what to expect and what to do:
If a front tire fails, the flat tire will create a drag that pulls the vehicle
toward that side. Take your foot
off the accelerator pedal and grip the
steering wheel firmly. Steer
to maintain lane position, then gently brake
to a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout,
remove your foot from the accelerator pedal. Get the vehicle under
control by steering the way you want the vehicle to go. It may be
very
bumpy and noisy, but you can still steer. Gently brake to a stop, well off
the road if possible.
If a tire goes flat, the next section shows how to use your jacking
equipment to change a flat tire safely.

Downloaded from www.Manualslib.com manuals search engine If you use an improper coolant mix, your engine could overheat
and be badly damaged. The repair cost wouldn’t be covered by
your warranty.
Too much water in the mix can freeze and crack
the engine, radiator, heater core and other parts.

Adding Coolant
Your cooling system when hot is under a lot of pressure. If the “ENGINE
COOLANT LOW” message should appear on the Driver Information
Center, you will need to
add coolant.
If the “ENGINE COOLANT LOW” message does not appear, the
coolant is
at the proper fill level.

Downloaded from www.Manualslib.com manuals search engine To Add Coolant
If you need more coolant, add the proper mix at the coolant surge tank.
To Check or Add Coolant
When the engine is cold, remove the pressure cap from the surge tank;
use
a flashlight as necessary to see into the tank. The coolant level should
be visible inside the tank.
If you need more coolant, add the proper mix.
