climate control CADILLAC DEVILLE 1997 7.G Owners Manual

Downloaded from www.Manualslib.com manuals search engine For the 1948 model, Cadillac introduced the legendary
tail fin which once more set the trend in automotive
styling for nearly two decades. This was closely
followed with the two door hardtop Coupe DeVille and
the industry's first modern overhead valve, high compression
V8 engine on the 1949 model.
Engineering innovations, conveniences and styling dominated the
'50s and '60s. Cruise control, automatic
climate control, tilt and telescoping steering wheels,
twilight sentinel and four door hard tops all debuted in
these years. In 1957 the Eldorado Brougham featured advances such as air suspension, memory seat,
automatic electric door locks, transistor radio, a brushed
stainless steel roof and low profile tires.

It’s better not to park with the engine funning. But if you
ever have to, here are some things to know.
A CAUTION:
Idling the engine with the climate control system
off could allow dangerous exhaust into
your vehicle (see the earlier Caution under
“Engine Exhaust”).
Also, idling in a closed-in place can let deadly
carbon monoxide
(CO) into your vehicle even if
the fan switch is at the highest setting. One place
this can happen is a garage. Exhaust

CO
-- can come in easily. NEVER park in a
garage with the engine running.
Another closed-in place can be a blizzard. (See “Blizzard” in the Index.)

With the full center console (available on DeVille
Concours only), press on the cover, which
is located
below the climate control system, to reveal the front
ashtray.
To clean this ashtray, lift it out by gripping the
sides. For vehicles without the center console, pull the
tray out to reveal the ashtray. The tray is located beneath
the radio.
To clean this ashtray, lift it out by pulling on
the snuffer.
To use the rear ashtray, lift the lid.
NOTICE:
Don’t put papers or other flammable items
into your ashtrays. Hot cigarettes
or other
smoking materials could ignite them, causing
a
damaging fire. The cigarette lighter
is located near the ashtray. Press it
all the way in
and release. It will pop back by itself
when it’s ready to light. You may also have
a lighter
located at the rear seat air outlet.
Note that power to the cigarette lighter will shut off
10 minutes after the ignition is turned off. This helps to
prevent battery drainage. For more information, see
“Inadvertent Battery Saver” earlier in this section.
NOTICE:
Don’t hold a cigarette lighter in with your hand
while
it is heating. If you do, it won’t be able to
back away from the heating element when it’s
ready. That can make it overheat, damaging the
lighter and the heating element.

Downloaded from www.Manualslib.com manuals search engine Driver Information Center Messages
These messages will appear if there is a problem sensed
in one of your vehicle’s systems. Vehicles that
are first
sold in Canada will have a number after each message.
This number helps to identify the message which is only
displayed
in English.
A/C OFF FOR ENGINE PROTECTION - 16: This
message displays when the engine coolant becomes
hotter than the normal operating temperature.
To avoid
added strain on a hot engine, the air conditioning
compressor is automatically turned off
so that air
conditioned
air is not delivered. If the coolant
temperature returns to normal, you must select AC to
return to a normal A/C compressor operation.
If this
message continues to appear, have the system repaired
as soon as possible to avoid compressor damage.
APPLY BRAKE TO SHIFT - 46: This message will
appear if your vehicle is in PARK
(P) for about 15
seconds and the brake
is not pressed in. To remove this
message from the DIC display, hold the
OFF and the
blue (cooler) buttons on the digital cluster climate control panel for about five seconds. On the analog
cluster climate control panel, press the
OFF button (next
to the
MODE button) and the down arrow on the PASS
TEMP button for about five seconds. Hold the same two
buttons to display the message again.
BATTERY NO CHARGE - 07: This message will
appear if the battery
is not being charged. Have the
electrical system checked by your Cadillac dealership at
your earliest convenience.
BATTERY VOLTS HIGH - 08: 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.
You can reduce the charging overload by using the
accessories. Turn on the lamps and 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 DIC by pressing the INFORMATION
(INFO) button. The normal range is 11.5 to 15.5 volts
when the engine is running.
BATTERY VOLTS LOW - 06: 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 the accessories. You can monitor battery

temperature is over 248
“F (1 26 “C). To avoid added strain
on a hot engine, turn off the climate control system. Stop
and allow your vehicle to idle until it cools down or the
message is removed.
If it does not cool down, turn off the
engine and have it serviced before driving it again. Severe
engine damage can result from an overheated engine. See “Engine Overheating” in the Index,
