Charge Light
When you turn the key
to “Run,” this light will
come on briefly, to
show that your
alternator and battery
charging systems are
working.
If a light stays on, you need service, and you should take your Cadillac to
the dealer at once.
To save your battery until you get there, turn off all
accessories, and set your Electronic Climate Control system to “OFF.”

you may choose
60 F (16 ’ C), for maximum cooling, and 90 F (33 ’ C),
for maximum heating.
Then, you have these choices:
Off
Nothing is on, but air will flow rnrough your vehicle if you are moving.
The system will attempt to maintain the chosen temperature, but may
never reach it, because the blower motor will not operate.
Econ
Use “Econ” in cold or cool weather, because it saves fuel by not allowing
the
A/C compressor to run. But it doesn’t remove humidity from the air.
If it’s so warm outside that you need to cool the air, use the next choice. I 1
Auto
In “Auto” its all automatic.
If your car is sitting out on a hot day and you have it set on “Auto”, the air
LJ
will first flow out the floor air ducts for a few seconds. That’s normal.
This
is to prevent a blast of hot air hitting you.
Fan Speeds
m Th e speed of the
blower fan is usually
controlled
I I automatically if you
have the fan on “Auto
Fan”. However, if you
want the blower fan to
run only at high speed,
push the “Hi” button
until you see “Hi Fan”
on the display.
If you want the blower to run only at low speed, push the “Lo7’ button
until you see
“Lo Fan” on the display. If you want the system to be
automatic, but you like the fan speed a little higher than the “Auto Fan”
speed, push the
“LO” or “Hi” button until you see the “Hi Fan Auto Fan”

light will come on
to tell you it is
working.
The system will go off after a four minute heating cycle (two minutes if
you shift out
of “P” (Park) within the first two minutes of the cycle). If
you want it to cycle again, push the switch. It will go
on for two minute
cycles after that.
If it has cleared your windshield before the cycle is over,
you can turn it
off by just pushing the switch again.
In warm weather the heated windshield system helps keep the vehicle’s
interior cool by blocking much
of the sun’s heat producing radiation. The
system’s solar control properties also help reduce interior fading.
There is a metal film in the windshield which will block out some radio or
microwave signals. Therefore, the heated windshield will reduce the
useful range of devices such as garage door openers and radar detectors.
(In certain states radar detectors are legal.)
Rear Window Defogger
To get fog or ice off the
rear window, push the
Rear Defogger button.
With it, your rear window and both outside rearview mirrors are warmed.
To turn it off, push the button again. After 10 minutes, it will go off by
itself.
To make it go longer, just push the button again.

It’s important to check occasionally to be sure the trailer bulbs are still
working.
Your vehicle has bulb warning lights. When you plug trailer lights into
your vehicle’s lighting system, its bulb warning lights may not let you
know if one
of your lights goes out. So, when you have trailer lights
plugged in, be sure to check your vehicle and trailer lights
from time to
time to be sure they’re all working. Once you disconnect the trailer lights,
the bulb warning lights again can tell you if one of your vehicle lights is
out.
Driving On Grades
Reduce speed and shift to a lower gear before you start down a long or
steep downgrade.
If you don’t shift down, you might have to use your
brakes
so much that they would get hot and no longer work well.
On a long uphill grade, shift down to “3” (Drive) and reduce your speed
to
45 mph (70 km/h) to reduce the possibility of engine and transaxle
overheating.
Parking on Hills
You really should not park your vehicle, with a trailer attached, on a hill.
If something goes wrong, your rig could start to move. People can be
injured, and both your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s how to do it:
1. Apply your regular brakes, but don’t shift into “P” (Park) yet.
2. Have someone place chocks under the trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until
the chocks absorb the load.
4. Reapply the regular brakes. Then shift into “P” (Park) firmly and
apply your parking brake.
5. Release the regular brakes.

you may have
a leak in the radiator hoses, heater hoses, radiator, water
pump or somewhere else in the cooling system.
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.
Dodbrun 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 Pied 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.
