1993 OLDSMOBILE SILHOUETTE air condition

Temperature and Compass
Display
The outside air temperature and the
compass are displayed at the front of the
overhead console. The control switches
are located to the left of the display.
Turn the display on or
off by pressing
the
ON/OFF switch. Display the
temperature
in either degrees Fahrenheit
(English) or Celsius (metric) by pressing
the
USIMET switch.
If the outside temperature is 37" F (3" C)
or lower when you
turn on the ignition,
ICE will appear briefly on the display.
It's there to caution the driver that road
conditions may be
icy and that
appropriate precautions should be taken.
Compass Calibration:
The compass is self-calibrating, so it
does not need to be manually set.
However, when your Silhouette is new,
the compass may function erratically.
If
it does, CAL (Calibration) will appear
on the display. To correct the problem,
drive in a complete
360" circle three
times, and the compass will function
normally.
Compass Variance:
Variance is the difference between
magnetic north and geographic north.
In
some areas the difference between the
two can be great enough to cause false
compass readings.
If this happens,
follow these instructions to set the
variance for your particular location:
1. Locate your location on the zone
map. Note your zone number.

Climate Control System
Your vehicle’s heater and air conditioner
work best
if you keep your windows
closed. Your vehicle also has
flow-
through ventilation, described later in
this section, to bring outside air into
your vehicle.
If you have the optional engine block
heater and use it during cold weather,
0°F (-18°C) or lower, your heating
system will more quickly provide heat
because the engine coolant is already
warmed. See the
Index under Engine
Block Heater.
OFF Press to turn the system off. Press
any climate control setting to turn the
system
on.

Temperature Control Lever: Slide the
lever to the right for warmer, heated air;
slide it to the left for cooled air.

When the air conditioner compressor is
on, you may sometimes notice slight
changes in your vehicle’s engine
performance and power. This is normal,
because the system is designed to help
fuel economy while it maintains the
desired cooling level.
The air conditioner removes moisture
from the air,
so you may sometimes
notice water dripping from under your
vehicle when it is idling or after it has
been turned off. This is normal.
On very hot days, your vehicle will cool
down more quickly and economically if
you open the windows long enough to
let hot inside air escape. For all settings,
adjust the temperature control lever and
fan speed as desired.
Directional Controls
RECIRC (Recirculate): Press to get
maximum cooling or quick cool-down
on very hot days. This setting
recirculates much of the air inside your
vehicle.
It should not be used for long
periods
of time because the air may
become too cold and dry.
Slide the temperature control lever down
to the coolest setting and adjust the fan
speed as desired.
UPPER: For normal cooling on hot
days, press
A/C along with UPPER.
This setting cools outside air and directs
it through the instrument panel outlets.
Adjust the temperature of the air with
the temperature control lever.
BI-LEV (Bi-Level): This setting is
designed for use
on sunny days when
the air is only moderately warm or cool.
On days like these, the sun may
adequately warm your upper body, but
your lower body may not be warm
enough.
The
BI-LEV setting directs outside air
into your vehicle
in two ways. Cooler
air is directed toward your upper body
through the front instrument panel
outlets, while warmed air
is directed
through the heater ducts at your feet.
At
times this temperature difference may be
more apparent than others. For best
results, slide
the temperature control
lever to the middle position, and then
adjust for comfort.

Rear Fan-Rear Control
This feature allows passengers riding in
the rear seats to control the flow of air
to the rear area of the vehicle. When the
heater
is on, warmed air is directed to
the third row seats and to the rear side
windows to defog them. When the air
conditioner is on, cooled air
is directed
to the second and third row seats
through upper vents. (See the
Index
under Climate Control System. )
The rear control switch is located on the
armrest next to the second row seat, left
position. The rear fan master control on
the instrument panel must be in the
REAR position for the rear control
switch to operate.
Select the force of air you want, from
LOW to HI, by turning the switch to the
desired setting. To turn the rear fan
off,
turn the switch to OFF. The rear fan can
also be turned off at the master control.
Defogging and Defrosting
To rapidly defrost the windshield, slide
the temperature control lever
all the way
to
WARM and press DEF. Adjust the
fan to the highest speed.
To keep the windshield clear and bring
in heated
air through the heater ducts,
press
DEFOG.
When the temperature outside is above freezing, the air conditioner compressor
will run in these settings to help remove
moisture
from the air.

Your Driving and the Road
Driving with a Trailer (CONT.)
Backing Up
Hold the bottom of the steering wheel
with one hand. Then, to move the trailer
to the left, just move that hand
to the
left. To move the trailer to the right,
move your hand to the right. Always
back up slowly and, if possible, have
someone guide you.
Making Turns
When you’re turning with a trailer,
make wider
turns than normal. Do this
so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or
other objects. Avoid jerky or sudden
maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has
to have a different
turn signal flasher
and extra wiring. The green arrows on
your instrument panel will flash
whenever you signal
a turn or lane
change. Properly hooked up, the trailer
lights will also flash, telling other
drivers you’re about to
turn, change
lanes or stop.
When towing a trailer, the green arrows
on your instrument panel will flash for
turns even if the bulbs on the trailer are
burned out. Thus, you may think drivers
behind you are seeing your signal when
they are not. It’s important to check
occasionally to be sure the trailer bulbs
are still working.
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 and
reduce your speed to around
45 mph
(70 Wh) to reduce the possibility of
engine and transaxle overheating. If
your vehicle has a 3800 V6 engine, you
should also drive in
D instead of
Overdrive when towing a trailer on
fairly level roads. This will help your
engine and transaxle run cooler in
this
condition, too.
If you are towing a trailer that weighs
more
than 1,000 pounds (454 kg), and
you have an automatic transaxle with Overdrive, you may prefer to drive in
D
instead of Overdrive (or, as you need to,
a lower gear).

damaged. The costly repairs wou
not be covered bv vour warrantv.
If No Steam is Coming from Your
Engine:
If you get the overheat warning but see
or hear no steam, the problem may not
be too serious. Sometimes the engine
can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer. If you get
the overheat warning with no
sign of steam,
try this for a minute or so:
1 . Turn off your air conditioner.
2. Turn on your heater to full hot at the
highest fan speed and open the
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.

Temperature-A, B, C (CONT)
Warning: The temperature grade for
this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Those grades are molded on the
sidewalls of passenger car tires.
While the tires available as standard or
optional equipment on General Motors
vehicles may vary with respect to these
grades, all such tires meet General
Motors performance standards and have
been approved for use on General Motors vehicles.
All passenger type
(P Metric) tires must conform to Federal
safety requirements in addition to these
grades.
Wheel Alignment and
Tire Balance
The wheels on your vehicle were
aligned and balanced carefully at the
factory to give you the longest tire life
and best overall performance.
In most cases, you will not need to have
your wheels aligned again. However,
if
you notice unusual tire wear or your
vehicle pulling one way or the other, the
alignment may need to be reset. If you
notice your vehicle vibrating when
driving on a smooth road, your wheels
may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked
or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts,
and wheel nuts should be replaced. If
the wheel leaks air out, replace it
(except some aluminum wheels, which
can sometimes be repaired). See your
Oldsmobile dealer
if any of these
conditions exist.
Your dealer will know the kind of wheel
you need.
Each new wheel should have the same
load carrying capacity, diameter, width,
offset, and be mounted the same way as
the one it replaces.
If you need
to replace any of your
wheels, wheel bolts, or wheel nuts,
replace them only with
new GM
original equipment parts.
This way, you
will be sure you have the right wheel,
wheel bolts, and wheel nuts for your Oldsmobile model.
