air conditioning Oldsmobile Aurora 1998 Owner's Manuals

Engine Coolant Temperature Gage
This gage shows the engine
coolant temperature.
If the gage pointer moves into the red warning zone,
your engine is hot.
To prevent engine overheating, the
air conditioning compressor will turn
off automatically,
a fast-pulsed chime will sound, and the message
ENGINE
HOT ... A/C OW will appear in the information
center.
As the engine cools down, the air conditioning
compressor will automatically turn back on. If
the coolant temperature is over
261 OF (127 “C),
the message HOT. ..STOP ENGINE will appear. It
means that your engine coolant has overheated. If
you have been operating your vehicle under normal
driving conditions, you should pull off the road, stop
your vehicle and turn
off the engine as soon as possible.
The section “Problems on the Road,”
in this manual
explains what to
do. See “Engine Overheating” in
the Index.
If your coolant level
is low, the message LOW ENGINE
COOLANT will appear on the Driver Information
Center. Check your coolant level
as soon as possible.
See “Engine Coolant” in the Index.

Operating the RECIRC mode in cold temperatures or
under high humidity conditions may cause moisture to
form on the inside of the windshield.
If this condition
occurs, deselect the RECIRC button.
A/C ON: Press this button to turn the air conditioning
on and
off. If the system is operating in the automatic
mode, the A/C
ON indicator light will automatically
illuminate. In the auto mode, the
A/C compressor will
only operate when the system determines it
is needed.
OFF: Rotate the AUTO-PUSH knob to OFF. Turning
the system off will cause the fan to turn off and the
airflow to be directed out the lower floor outlets. The
system will still try to keep the interior
of the vehicle at
the previously chosen
comfort setting. The outside
temperature will show in the display when the system is
set to
OFF.
Air Conditioning
The air conditioner cools, dehumidifies and filters the
air for the inside of the vehicle.
The air conditioning compressor is enabled in all modes
unless the A/C
ON button is in the off position (the
indicator light will not be illuminated). However, the air
conditioning compressor will not operate when the
outside temperature is below
42°F (7 "C). When the air
conditioner is on, you may sometimes notice slight
changes
in your vehicle's engine speed and power. This
is normal, because the system is designed to cycle the
compressor on and off to keep the desired cooling and
help fuel economy.
On very hot days, open the windows long enough to let
the hot air out. This reduces the time required to cool the
interior of the vehicle to a comfortable level. If the
system is in the automatic mode (AUTO-PUSH knob
indicator light is on), during very hot days the system
will automatically
go to the RECIRC mode and the
temperature door will be positioned at
the full cold
position for maximum cooling.
You can choose the
extreme comfort setting of
60" F (1 6 O C), but the
system will not cool any faster by choosing the extreme
comfort setting.

@ Section 6 Service and Appearance Care
Here you will find information about the care of your vehicle. This section begins with service and fuel information,
and then it shows
how to check important fluid and lubricant levels. There is also technical information about your
vehicle, and a part devoted to its appearance care.

Part C: Periodic
Maintenance Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your retailer’s service
department or other qualified service center do these
jobs. Make sure any necessary repairs are completed
at once.
Proper procedures to perform these services may be
found
in a service manual. See “Service and Owner
Publications” in the Index.
Steering, Suspension and Front Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See “Engine Exhaust”
in the Index.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of the
cooling system and pressure cap is recommended at
least once a year.
