1998 PONTIAC BONNEVILLE Owners Manual

The earth’s magnetic field is not always the same
direction as true north
as we know it. So, you must enter
a zone number to tell the compass the difference
between magnetic and actual north.
This tells the
compass where in the country you are driving.
The compass shows the zone number
in use each time
you
turn your key on. This is above the compass. The
number is turned
off after a few seconds.
Choosing Your Zone Number
The compass remembers your zone, so you only have to
change
it if you drive to a new zone on the map. The
compass adjusts only a small amount for each zone, so
you may not notice a difference if you drive from one
zone to the next one, until you cross several zones.
Locate your zone number on the previous map. If your
number is Merent than the one shown when you turn the
key on, follow the steps to change your zone number.
If you live on the line, you can pick the zone area you
are most likely to drive in. (In Alaska use Zone 9 or 10.
In Hawaii use Zone 7).

r ZONE OS
1. Press and hold the MODE button until zone and the
zone number appear.
2. Release the MODE button.
3. Press the MODE button until your number appears.
4. In a few seconds, the zone number and ZONE turn
off, and the new zone number is remembered by
the compass.
Calibrating the Compass
(iZiF)
All electronic compasses need to know the magnetic
profile of your car. This is called calibration
and is done
automatically by your compass.
But, the feature is
available if you would like to manually calibrate.

Sometimes, strong magnetic fields can affect the
compass.
If the CALIBRATE light comes on as shown
above,
try calibrating the compass as follows:
1. Drive the car to an open, flat area.
2. Press and hold the MODE button until the
CALIBRATE light reappears.

Compass Accuracy
Your compass may show different headings around
bridges, power lines, large metal objects and steep hills.
This is noma1 and is true of compasses in general.
If you put large metal objects like golf clubs in the trunk
they could affect accuracy. If the accuracy is close, the
compass will adapt to
these objects over time.
If you use an antenna with a magnetic base, it is best
to mount it away from the center of the trunk near the
rear window.
The rear defog system can affect accuracy, and the
compass corrects for the rear defog. However,
if the rear
defog is turned on while making
sharp turns, the
accuracy may be
off. When you turn the rear defog off
again, the accuracy returns to normal.
Do not turn on the rear defog if you are trying to
calibrate. The system will not allow the calibration.
You
will hear the chime, and CALIBRATE will flash for a
few seconds.
Be aware that metal objects are sometimes buried in the
ground. They
can affect accuracy and you may not know
they are there.
As an example, many concrete roads
have
metal reinforcements inside.

Comfort Controls Temperature Knob
This section tells you how to make your air system work
for
you. Your comfort control system uses
ozone-friendly
R- 134a refrigerant.
With these systems, you can control the heating, cooling
and ventilation
in your vehicle. Your vehicle also has a
flow-through ventilation system described later
in
this section.
Standard Climate Control System
Fan Knob
The left knob is the fan knob and selects the force of air
you want. Turn the knob to the right to increase fan
speed and to the left to decrease fan speed. The fan will
always run unless the right control
knob is turned to
OFF. The fan must be on to run the air
conditioning compressor. The center control regulates the temperature
of the air
coming through the system.
Turn it toward the blue area
for cooler
air. Turn it toward the red area for wanner air.
Mode Knob
The right control has settings for air conditioning and
non-air conditioning modes. The mode control allows
you to choose the direction of
air delivery.
MAX: This setting provides maximum cooling with the
least amount
of work. MAX recirculates much of the air
inside your vehicle so it cools quickly. The air is
directed through the instrument panel outlets.
NC: This setting cools the air entering your vehicle
and directs it through the instrument panel outlets. The
air conditioning compressor operates in all air
conditioner positions.
1fl BI-LEVEL: This setting directs air into your
vehicle in two
ways. Cool air is directed to the upper
portion
of your body through the middle instrument
panel outlets
while warmed air is directed to the floor.
@ VENT: This setting directs airflow through the
middle instrument panel outlets. The air conditioning
compressor
is not working when VENT is selected.

‘fl HEATER: This setting directs warmed air
through the floor outlets. Some warm air is diverted to
the windshield to minimize fogging.
vfl DEFOG: This setting directs air to the HEATER
outlets and toward the windshield.

DEFROST: This setting directs most of the air
toward the windshield.
Fan Button
The button with the fan symbol adjusts the fan speed.
Press the up
arrow to increase fan speed and the down
arrow to decrease fan speed.
Temperature Button
The TEMP button changes the temperature of the air
coming through the system. Press the up arrow for
warmer
air and the down arrow for cooler air.
Electronic Climate Control system (option) Mode Button
Press this button to deliver air through the floor, middle
or windshield outlets. The system will stay in the
selected mode until the
MODE or AUTO button is
pushed. Press the
up arrow to cycle through the
available modes.
Automatic Operation
When the system is set for AUTO, sensors will control
middle and windshield outlets. The
fan speed will vary
as the system maintains the selected temperature setting.
