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

1. Check for holes and exhaust gas leaks due to damage,
corrosion, etc.
2. Check the joints and connections for looseness and exhaust
gas leaks.
3. Check the rubber hangers and brackets for damage.
9. ENGINE OIL (CHANGE)M1001002600360
Use the specified oil. (Refer to P.00-35.)
Use care as oil could be hot.
1. After warming up the engine, remove the oil filler cap.
2. Remove the drain plug to allow the engine oil to drain.
3. Install a new drain plug gasket so that it faces in the
direction shown in the illustration, and then tighten the drain
plug to the specified torque.
Tightening torque: 39
5 Nm (29 3 ft-lb)
4. Pour new engine oil in through the oil filler hole.
Specified Engine Oil:
To ta l q u a n t i t y :
<3.8L Engine> 4.6 Litres
5. Install the engine oil filler cap.
6. Start the engine and run it at idle for a few minutes.
7. Pull out the oil dipstick slowly and check that the oil level is
within the marks on the oil dipstick.
8. Check that the oil is not excessively dirty, that there is no
coolant or petrol mixed in, and that it has sufficient viscosity.
10. ENGINE OIL FILTER (REPLACE)M1001002700345
The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,800 kPa (261 psi) are high quality filters.

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.
