a Cadillac technician as soon as
possible.
If the brake warning light is on, follow the directions in that
section.

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.

To select the
temperature
you want,
push
the blue button
for a cooler setting and
the red button for a
warmer setting.
The
temperature setting
will be displayed
on
the digital screen.
I
You can select temperatures from 65 F ( 18 " C) to 85 F (69 " C). And, at
each end,
you may choose 60°F (16" C), for maximum cooling, and 903F
(33"C), for maximum heating.We recommend when first getting familiar
with your vehicle, select
75°F (24°C). You may find that your own
personal comfort requires a slightly higher or lower setting. Once you set
the temperature, the system will automatically maintain the set
temperature.
ECON
With this setting it's all automatic, but the air conditioningcorupressor
does not operate and
it won't remove humidity from the alr. However,
the system will try
to keep the air at the selected temperature. Use this
setting
in cold or cool weather to save fuel.
If it's warm outside and you need to cool the air, use the next choice.
AUTO
With this setting, the air conditioning compressor runs and it's all
automatic. In cold weather when the system senses the need for heat, the
air
flow will be directed out the floor ducts. As the interior temperature
approaches
the desired setting, the blower speed will decrease and the air
flow could be directed through the defroster and floor ducts. To maintain
interior comfort, the air
flow may move to the air outlets and floor ducts

Downloaded from www.Manualslib.com manuals search engine If you drive regularly in steep country, or if you’re planning to visit there,
here are some tips that can
make your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid levels and also the
brakes, tires, cooling system and transaxle. These parts can work hard
on mountain roads.
Know how to go down hills. The most important thing to know is this:
let your engine do some
of the slowing down. Don’t make your brakes
do it all. Shift to a lower gear when you go down a steep or long hill.
That way, you
will slow down without excessive use of your brakes.
<
A CAUTION: .r S<*.
If you don’t shift down, your brakes could get so hot that they ’+--*
wouldn’t work well. You would then have poor braking or even
none going down
a hill. You could crash. Shift down to let your
engine assist your brakes on
a stef downhil’ lope.
- - i. .*$
Coasting downhill in “N” (Neutral) or with the ignition off is
dangerous. Your brakes will have to do all the work of slowing
down. They could get
so hot that they wouldn’t work well. You
could crash. Always have your engine running and your vehicle
in gear when you
go downhill.
0 Know how to go uphill. You may want to shift down to a lower gear.
The lower gears help cool your engine and transaxle, and you can
climb the hill better.
Stay in your own lane when driving on two-lane roads in hills or
mountains. Don’t swing wide or cut across the center
of the road.
Drive at speeds that let you stay
in your own lane. That way, you won’t
be surprised by a vehicle coming toward
you in the same lane.

Your vehicle will need scrvice more often when you‘re pulling a trailer.
See the Maintenance Schedule for more
on this. Things that are
especially important in trailer operation are automatic transaxle fluid
(don’t overfill), engine
oil, axle lubricant, belts, cooling system, and brake
adjustment. Each
of these is covered in this manual, and the Index will
help you find them quickly. If you’re trailering, it’s a good idea to review
these sections before you start your trip.
Check periodically to see that
all hitch nuts and bolts are tight.

window as necessary.
3. Try to keep your engine under load (in a drive gear where the engine
runs slower).
If you no longer have the overheat warning, you can drive. Just to be safe,
drive slower
for about ten minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your vehicle right
away.
If there’s still no sign of steam, you can idle the engine for two or three
minutes while you’re parked, to see
if the warning stops. But then, if you
still have the warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT OF THE VEHICLE until it cools down.
You may decide not to lift the hood but to get service help right away.
COOLING SYSTEM- 4.9 LITER
When you decide it’s safe to lift the hood, here’s what you’ll see:
Coolant recovery tank
Radiator pressure cap
Electric engine fans

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.
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
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
z;:s- could lose all coolant. That could cause an engine fire, and you

When the coolant in the coolant recovery tank is at or above “FULL
COLD,” start your vehicle.
If the overheat warning continues, there’s one more thing you can try.
You
can add the proper coolant mix directly to the radiator, but be sure
the cooling system
is cool before you do it.

Downloaded from www.Manualslib.com manuals search engine Steam and scalding liquids from a hot cooling system can blow
out and burn you badly. They are under pressure, and if you
turn the radiator pressure cap
-- even a little -- they can come
out at high speed. Never turn the cap when the cooling system,
including the radiator pressure cap,
is hot. Wait for the cooling
system and radiator pressure cap to cool if you ever have to turn
the pressure cap.
