PRECAUTIONS BEFORE SERVICE
GENERAL00-24
SERVICING ELECTRICAL SYSTEMM1001011900057
Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER
HANDLING.
1. Note the following before proceeding with working on the
electrical system.
Never perform unauthorized modifications to any electrical
device or wiring. Such modifications might lead to a vehicle
malfunction, over-capacity or short-circuit that could result in
a fire in the vehicle.
Before connecting or disconnecting the negative bat-
tery cable, be sure to turn the ignition switch to the
"LOCK" (OFF) position and turn off the lights (If this is
not done, there is the possibility of semiconductor
parts being damaged).
After completion of the work (and the negative battery
terminals is connected), warm up the engine and allow
it to idle for approximately 10 minutes under the condi-
tions described below in order to stabilize engine con-
trol conditions, and then check to be sure that the idle
is satisfactory.
Engine coolant temperature: 85 to 95C (185 to
203
F)
Lights and all accessories: OFF
Transaxle: "N" or "P" position
Steering wheel: straight-forward position
2. When servicing the electrical system, disconnect the
negative cable terminal from the battery.
VEHICLE WASHINGM1001012000057
If high-pressure car-washing equipment or steam car-washing
equipment is used to wash the vehicle, be sure to maintain the
spray nozzle at a distance of at least approximately 50 cm (20
inches) from any plastic parts and all opening parts (doors, lug-
gage compartment, etc.).

SELECTION OF COOLANT
.
COOLANT
Relationship between Coolant Concentration and Specific Gravity
If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 50%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain
the concentration level within the specified range.
Do not use a mixture of different brands of anti-freeze.
Example
The safe operating temperature is
15C (5 F) when the specific gravity is 1.058 at the coolant temperature
of 20

MAINTENANCE SERVICE
GENERAL00-47
6. Securely insert the dipstick.
NOTE: The transmission fluid should always be replaced
under the following conditions:
.
When troubleshooting the transaxle.
When overhauling the transaxle.
When the transmission fluid is noticeably dirty or burnt
(driving under severe conditions).
TRANSMISSION FLUID CHANGE
Refer to GROUP 23A, Automatic Transmission - On-vehicle
Service P.23A-296.
12. ENGINE COOLANT (CHANGE)M1001003100357
Check the cooling system parts such as the radiator, heater
and oil cooler hoses, thermostat and their connections for leak-
age and damage.
.
CHANGING COOLANT
1. Set the temperature control knob to the "HOT" position.
2. Run the engine until the engine coolant warms, and then
stop the engine.
When removing the radiator cap, use care to avoid
contact with hot coolant or steam. Place a shop towel
over the cap and turn the cap counterclockwise a lit-
tle to let the pressure escape through the vinyl tube.
After relieving the steam pressure, remove the cap by
slowly turning it counterclockwise.
3. Drain the water from the radiator, heater core and engine
after unplugging the radiator drain plug and removing the
radiator cap.
