replaced with solid coolant on cool down.
TEMPERATURE GAUGE INDICATION
At idle the temperature gauge could rise slowly to
about 1/2 gauge travel. The fan will come on and the
gauge could drop to about 1/3 gauge travel, this is
normal.
SERVICE PROCEDURES
COOLANT LEVEL CHECKÐROUTINE
NOTE: Do not remove radiator cap for routine cool-
ant level inspections.
The coolant reserve system provides a quick visual
method for determining the coolant level without
removing the radiator cap. Simply observe, with the
engine idling and warmed up to normal operating
temperature, that the level of the coolant in the
reserve tank (Fig. 12) is between the add and full
marks.
COOLANTÐADDING ADDITIONAL
NOTE: The radiator cap should not be removed.
When additional coolant is needed, it should be
added to the coolant reserve tank. Use only 50/50
concentration of ethylene glycol type antifreeze and
water
COOLANT LEVELÐSERVICING
NOTE: The cooling system is closed and designed
to maintain coolant level to the top of the radiator.When servicing requires a coolant level check in
the radiator, the engine must beoffandnotunder
pressure. Drain several ounces of coolant from the
radiator drain cock while observing the Coolant
Recovery System (CRS) Tank. Coolant level in the
CRS tank should drop slightly. Then remove the radi-
ator cap. The radiator should be full to the top. If
not, and the coolant level in the CRS tank is at the
ADD mark there is a air leak in the CRS system.
Check hose or hose connections to the CRS tank,
radiator filler neck or the pressure cap seal to the
radiator filler neck for leaks.
COOLING SYSTEMÐDRAINING
NOTE: Drain, flush, and fill the cooling system at
the mileage or time intervals specified in Group 0,
Lubrication and Maintenance. If the solution is dirty,
rusty, or contains a considerable amount of sedi-
ment; clean and flush with a reliable cooling system
cleaner. Care should be taken in disposing of the
used engine coolant from your vehicle. Check gov-
ernmental regulations for disposal of used engine
coolant.
Without removing radiator pressure cap and
with system not under pressure:
(1) Shut engine off and turn draincock counter-
clockwise to open (Fig. 13).
(2) The coolant reserve tank should empty first,
then remove the pressure cap. (if not, Refer to Test-
ing Cooling System for leaks).

GENERAL INFORMATION
INTRODUCTION
The purpose of the dash gauges and indicator
lamps is to keep the driver informed about the oper-
ating condition of the vehicle. If an abnormal condi-
tion occurs, the driver is informed by indicator lamp.
The driver can seek service before damage occurs.
Indicator lamps use ON/OFF switch functions for
operation, while gauges use a sending unit or sensor.
DESCRIPTION AND OPERATION
DOME LAMP
The Dome Lamp operates when a door is open or
when the headlamp switch is placed in courtesy posi-
tion.
ELECTRONIC DIGITAL CLOCK
The electronic digital clock is in the radio. The
clock and radio each use the display panel built into
the radio. A digital readout indicates the time in
hours and minutes whenever the ignition switch is in
the ON or ACC position.
PLINSTRUMENT PANEL AND SYSTEMS 8E - 1

When the ignition switch is in the OFF position, or
when the radio frequency is being displayed, time
keeping is accurately maintained.
The procedure for setting the clock varies slightly
with each radio. The correct procedure is described in
the individual radio operating instructions. Refer to
the Owner's Manual supplied with the vehicle.
INSTRUMENT CLUSTER
There are two conventional instrument cluster
assemblies available. The clusters electronically drive
the speedometer, odometer, and gauges (Fig. 1) and
(Fig. 2).
GAUGES
All gauges in the electronic clusters are the analog
type gauges. When the ignition switch is moved to
the OFF position, the cluster drives each gauge to its
lowest position.
WARNING AND INDICATOR LAMPS
The instrument cluster has warning lamps and
indicators for the following systems:
²Airbag
²Anti-lock Brakes (ABS) if equipped
²Brake warning
²Charging System
²Door Ajar
²High beam indicator

GENERAL INFORMATION
INTRODUCTION
Operating instructions for the factory installed
audio systems can be found in the Owner's Manual
provided with the vehicle.
The vehicles are equipped with an Interior (Igni-
tion Off Draw) fuse in the Power Distribution Center
located in the engine compartment. After the Interior
(IOD) fuse or battery has been disconnected the clock
will require resetting.
DESCRIPTION AND OPERATION
INTERFERENCE ELIMINATION
The radio utilizes a ground wire plugged on to a
blade terminal and is bolted to the radio chassis.
Both connector and terminal should be securely
attached. The engine has three separate ground
straps to suppress ignition noise which may interfere
with radio reception.
²Left engine mount clip on strap
²Engine to shock tower reinforcement
²Rear strut to body, clip-on strap
Inductive type spark plug cables in the high ten-
sion circuit of the ignition system complete the inter-
ference suppression. Faulty or deteriorated spark
plug wires should be replaced.
In addition, there is a capacitor mounted on the
cylinder head which also helps suppress ignition
noise.

AIRBAG REMOVAL PROCEDURES.
The turn signals are part of the multi-function
switch. Which contains:
²Electrical circuitry for turn signals
²Hazard warning switch
²Headlamp beam select switch
²Headlamp optical horn
The integrated switch assembly is mounted to the
left hand side of the steering column. When the
driver wishes to signal his intentions to change direc-
tion of travel, he moves the lever upward to cause
the right signals to flash and downward to cause the
left signals to flash. After completion of a turn the
system is deactivated automatically. As the steering
wheel returns to the straight ahead position, a can-
celing cam molded to the clockspring mechanism
comes in contact with the cancel actuator on the turn
signal multi-function switch assembly. The cam lobe,
pushing on the cancel actuator, returns the switch to
the off position.
If only momentary signaling such as indication of a
lane change is desired, the switch is actuated to a
left or right intermediate detent position. In this
position the signal lamps flash as described above,
but the switch returns to the OFF position as soon as
the lever is released.
When the system is activated, one of two indicator
lamps mounted in the instrument cluster flashes in
unison with the turn signal lamps, indicating to the
driver that the system is operating.
DESCRIPTION AND OPERATION
HAZARD WARNING SYSTEM
The hazard warning system is actuated by a slide
button located on the top of the steering column
between the steering wheel and the instrument
panel. The hazard switch is identified with a double
triangle on front of the button.
COMBINATION FLASHER
The turn signal flasher and the hazard warning
flasher are combined into one unit called a combina-
tion flasher (combo-flasher). The combo- flasher con-
trols the flashing of the hazard warning system and
the turn signal system. An inoperative bulb or incom-
plete turn signal circuit will cause the flasher rate to
double.
The combo-flasher is located on the fuse block. The
combo-flasher is black in color for ease of identifica-
tion (Fig. 1).
