MAP READING LAMPS
The map reading and rear passenger lamps are
turned on and off by pressing their individual switch
marked LAMP. These same lamps also serve as cour-
tesy lamps whenever a door is opened, the illumi-
nated entry system is activated, or the headlamp
switch is turned fully clockwise.
LAMP REPLACEMENT
(1) Remove lens by inserting a large paper clip or
wire, with a hook on the end, into the hole in the
lens and pull downward (Fig. 1).
(2) Remove lamp by pulling firmly toward front of
vehicle.
(3) Install new lamp by pushing firmly into recep-
tacle.
(4) Snap lens into position taking care to orient
the tabs on the lens with the slots in the housing and
snap into position.
LAMP TEST
(1) Close vehicle doors.
(2) Press each lamp switch button (Fig.2). Right
hand button should light passenger side lamp and
left hand button should light drivers side lamp front
or rear.
(3) If any of the lamps fail to illuminate, open ve-
hicle doors:
(a) If lamp does not illuminate check for a
burned out lamp. If lamp is OK, check fuse and
wire connectors.
(b) If lamp illuminates when doors are open
check switch.
THERMOMETER AND COMPASS OPERATION
The ignition switch must be in the ON or ACCES-
SORY position before the temperature and compass
reading can be displayed. The Comp/Temp switch, lo-
cated left of the display module, turns the display on
and off. The US/Metric switch, located right of the dis-
play, changes the temperature reading from Fahrenheit
to Celsius. Should the compass blank out and the CAL
symbol only light, demagnetizing may be necessary.
The compass is a flux-gate system which, is inte-
gral to the console. The temperature readout is con-
nected to a thermistor sensor which, located on the
front lower radiator closure panel.

When the vehicle is standing still, engine compart-
ment temperature may be radiated to the tempera-
ture sensor. Therefore the most accurate ambient
temperature readings are displayed when the vehicle
is moving in a forward motion.
When the ignition switch is turned off the last dis-
played temperature reading stays in memory. When
the ignition switch is turned on again the thermom-
eter will display the memory temperature for 1
minute; then update the display to the actual tem-
perature within 5 minutes. Refer to Compass and
Thermometer Diagnosis (Fig. 3).
COMPASS CALIBRATION
The compass unit automatically calibrates itself as
the vehicle is driven; therefore, no calibration should be
required. When the compass is first powered up, the
CAL light on the display should be on. The CAL light
will go off and the compass will be accurate after the
vehicle completes one to three complete circles.
Do not attempt to set the compass near large metal
objects, such as, other vehicles, large buildings, or
bridges.
If the vehicle’s compass headings are inaccurate,
the compass also can be manually calibrated using
the following procedures:
(1) Depress and hold down both the Comp/Temp
button and the U.S./Metric button.
(2) The display will go off and after 5 seconds the
VAR light will come on. Continue to hold both but-
tons down.
(3) In approximately 10 seconds, the CAL light
will come on. Release both buttons and the display
will show the heading and outside temperature.
(4) Release buttons the CAL light will then go off,
showing the compass is calibrated.
(5) The variation may need to be adjusted. The
variation is the difference between magnetic north
and true north. To set variation refer the to Varia-
tion Setting Procedure.
If the compass portion of the display is not lit or
compass readings are not accurate after calibration.
The vehicle may have too much magnetism for the
compass to be accurate or the compass circuitry is
not working properly. Refer to Variance Procedure,
Demagnetizing Procedure and/or Compass Diagnos-
tics.
VARIANCE
Variance is the difference between magnetic North
and geographic North. In some areas the difference
between magnetic and geographic north is great
enough to cause the compass to give false readings. If
this occurs, the variance must be set.
