Comfort Controls & Audio Systems
Standard Climate
Control
The air conditioner and heater work best
if you keep your windows closed while
using them.
% : Selects the force of air you want.
The fan is always running unless the
mode control is moved to
“OFF”.
Temperature Control: The center
control regulates the temperature of the
air coming through the system.
Mode Control: The right control has
settings for air conditioning and non-air
conditioning modes.
Air Conditioning Settings
There are three air conditioning settings.
On very hot days, open the windows long
enough
to let hot inside air escape. This
reduces the time your air conditioner’s
compressor will have to run, which
should help fuel economy.
MAX: Provides maximum cooling or
quick cool-down
on very hot days. This
setting recirculates much of the air inside
your vehicle, and
it should not be used for
long periods because the air may become
too cold and dry.
A/C: Use for normal cooling on hot days.
This setting cools outside air and directs
it
through the instrument panel outlets.
‘H (Bi-Level): Use on cool, but sunny
days. This setting brings in the outside air,
but directs it in two ways. The cool air is
directed to the upper portion
of your body
through the instrument panel outlets, but
warmed air
is directed through the heater
ducts and defroster vents. At times this
temperature difference may be more
apparent than others.
The air conditioner compressor operates
in all air conditioner positions, and in
A0
we
(Defrost) and ’# (Defog) when the
outside temperature is above
42°F. 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.

Non-Air Conditioning
Settings
A0
r/ (Vent): This setting brings in the
outside air and directs
it to the upper
portion of your body through the
instrument panel outlets.
’N (Heat): This setting directs warmed
air through the heater ducts. Some warm
air is diverted to the windshield to
minimize fogging.
The air conditioner compressor doesn’t
run in the non-air conditioning settings.
This reduces engine load, resulting
in
improved fuel economy. If the non-air
conditioning settings do not maintain the
comfort of the air inside your vehicle,
move the selector to
“MAX” or “A/,”. If
your windows fog up, move the mode
selector tow (Defrost) or
“A/C”.
0
Defrosting
The %? (Defrost) setting directs most air
through the defroster vents, and some
through the heater ducts. Use this when
you have fog or ice on the windshield.
When it’s
42°F or warmer outside, you’ll
get cooled air.
Defogging Windows With Standard Climate Control
Move the temperature control to
maximum heat.
To quickly defog the windshield, set the
right selector to
%? (Defrost) and turn
the fan control to “HIGH’’.

Rear Vents
Slide the center control up to direct air
upward. Slide it down to direct air
downward. Slide the ridged vent control
levers sideways to direct air right or left.
Flow-Through Ventilation
System
Your Pontiac's flow-through ventilation
system supplies outside air into the
vehicle when it is moving. Outside air
will also enter the vehicle when the heate
or the air conditioning fan is running.
Ventilation Tips
0 Keep the hood and front air inlet free
of ice, snow, or any other obstruction
(such as leaves). The heater and
defroster will work far better, reducing
the chance of fogging the inside of
your windows.

Engine Accessory Belt
The 3800 (L27) engine uses an engine
accessory belt. This diagram shows the
features connected by the belt routing.
See “Maintenance Schedule’’
in the Index
for when to check the belt.
A. Power Steering
B. Crank
C. Coolant Pump
D. Air Conditioning
E. Alternator
F. Tensioner
3800 Supercharged
(L67) Engine (OPTION)
Your Bonneville may have a 3800
Supercharged engine. The Supercharger is
a device which is designed to pump more
air into the engine than
it would normally
use. This air mixed
with fuel, creates
increased engine power. Since the
Supercharger is a pump and is driven
from an engine accessory drive belt,
increased pressure is available at all
driving conditions, The Powertrain Control
Module
(PCM),
works with a vacuum control to regulate
the increased pressure required during
specific driving conditions. When this
increased pressure or boost is
not desired,
such as during idling and light throttle
cruising, the excess air that the
’
Supercharger is pumping is routed,through
a bypass. All of these controls, working
together provide high performance
character and fuel efficiency
in the3800
V6 Supercharged engine.
The power steering pump uses a Remote
reservoir mounted on the throttle wd
cruise control cable bracket. See
“Maintenance Schedule”
in the Index for
when you should check the fluid:

tngine Accessory Belt
‘he Supercharged 3800 engine uses two
ccessory drive belts. One belt drives the
enerator and the power steering pump.
‘he second belt drives the supercharger,
oolant pump and air conditioning
ompressor. Each belt has its own
msioner and idler pulley.

See “Maintenance Schedule” in the Index
for when to check the accessory drive
belts and Supercharger oil level. Have
your dealer check the oil level in the
Supercharger.
Supercharger Oil
Unless you are technically qualified and
have the proper tools, you should let your
dealer or a qualified service center
perform this maintenance.
When to Check
Check oil level every 30,000 miles
(50 000 km) or every 36 months.
What Kind of Oil to Use
See “Recommended Fluids and
Lubricants” in the Index and use only the
recommended oil.
How to Check and Add Oil
Check oil only when the engine is cold.
Allow the engine to cool
2 to 3 hours after
running.

Maintenance Schedule
Explanation of Scheduled Maintenance
Services
Following are explanations of the services listed in Schedule I
and Schedule
11.
The proper fluids and lubricants to use are listed in Section D.
Make sure whoever services your vehicle uses these. All parts
should be replaced and all necessary repairs done before you or
anyone else drives the vehicle.
1. Engine Oil and Filter Change* -- Always use SH or SG
Energy Conserving I1 oils
of proper viscosity. The “SH” or
“SG” designation may be shown alone or in combination
with others, such as “SH/CD,” or “SH, SG, CD,” “SG/CD,”
etc. To determine the preferred viscosity for your vehicle’s
engine (e.g., SAE 5W-30 or SAE
10W-30), see “Engine
Oil”
in the Index.
2. Chassis Lubrication -- Lubricate suspension and steering
linkage. Lubricate the transaxle shift linkage, and parking
brake cable guides, underbody contact points and linkage.
3. Tire and Wheel Rotation and Inspection -- For proper
wear and maximum tire
life, rotate your tires following the
instructions in this manual. See “Tires, Inspection &
Rotation” in the Index. Check the tires for uneven wear or
damage. If
you see irregular or premature wear, check the
wheel alignment. Check for damaged wheels also.
4. Engine Accessory Drive Belt(s) Inspection* -- Inspect
the belt(s) for cracks, fraying, wear and proper tension.
Replace as needed. (Belts can have many small cracks
in
individual ribs without affecting performance.)
5. Cooling System Service* -- Drain, flush and refill the
system with new or approved recycled coolant conforming
to GM Specification 1825M. Keep coolant at the proper
mixture as specified. See “Coolant”
in the Index. This
provides proper freeze and boil protection, corrosion inhibitor level and maintains proper engine operating
temperature.
Inspect hoses and replace
if they are cracked, swollen or
deteriorated. Tighten screw-type hose clamps. Clean the
outside of the radiator and air conditioning condenser. Wash
the pressure cap and neck.
To help ensure proper operation, we recommend a pressure
test of both the cooling system and the pressure cap.
