MAINTENANCE, REPAIR AND
SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Unless otherwise
specified, each service procedure covers all models.
Procedures covering specific models are identified
by the model codes, or similar designation (engine
type, transaxle type, etc). A description of these des-
ignations is covered in this manual under "VEHICLE
IDENTIFICATION."
.
ON-VEHICLE SERVICE
The "ON-VEHICLE SERVICE" section has proce-
dures for performing inspections and adjustments of
particularly important components. These proce-
dures are done with regard to maintenance and ser-
vicing, but other inspections (looseness, play,
cracking, damage, etc.) must also be performed.
.
SERVICE PROCEDURES
The service steps are arranged in numerical order.
Attention to be paid in performing vehicle service are
described in detail in SERVICE POINTS.
DEFINITION OF TERMS
.
STANDARD VALUE
Indicates the value used as the standard for judging
whether or not a part or adjustment is correct.
.
LIMIT
Shows the maximum or minimum value for judging
whether or not a part or adjustment is acceptable.
.
REFERENCE VALUE
Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be com-
pleted in a shorter time).
.
DANGER, WARNING, AND CAUTION
DANGER, WARNING, and CAUTION call special
attention to a necessary action or to an action that
must be avoided. The differences among DANGER,
WARNING, and CAUTION are as follows:
If a DANGER is not followed, the result is severe
bodily harm or even death.
If a WARNING is not followed, the result could be
bodily injury.
If a CAUTION is not followed, the result could be
damage to the vehicle, vehicle components or
service equipment.
TIGHTENING TORQUE INDICATION
The tightening torque indicates a median and its tol-
erance by a unit of N
m (in-lb.) or Nm (ft.-lb.). For
fasteners with no assigned torque value, refer to
P.00-32.
SPECIAL TOOL NOTE
Only MMC special tool part numbers are called out in
the repair sections of this manual. Please refer to the
special tool cross-reference chart located at the
beginning of each group, for the special tool number
that is available in your market.

TOWING AND HOISTING
GENERAL00-27
TOWING WITH REAR WHEELS OFF THE
GROUND (TYPE B)
Place the gearshift lever in the "Neutral" position (M/T) or the
selector lever in the "N" (NEUTRAL) position (A/T). Turn the
ignition key to the "ACC" position and secure the steering
wheel in a straight-ahead position with a rope or tie-down strap.
Never place the ignition key in the "LOCK" position when tow-
ing.
Never tow an A/T vehicle with the rear wheels up (and
the front wheels on the ground) when the automatic
transmission fluid level is low. this may cause serious
and expensive damage to the transmission.
Do not use the steering column lock to secure the front
wheels for towing.
Make sure the transaxle is in Neutral if vehicle will have
drive wheels on the ground.
If these requirements cannot be met, the front wheels
must be placed on a tow dolly.
.
TOWING WHEN KEYS ARE NOT AVAILABLE
When a locked vehicle must be towed and keys are not avail-
able, the vehicle may be lifted and towed from the front, pro-
vided the parking brake is released. If not released, the rear
wheels should be placed on a tow dolly.
.
SAFETY PRECAUTIONS
The following precautions should be taken when towing the
vehicle:
1. DO NOT LIFT OR TOW THE VEHICLE BY ATTACHING
TO OR WRAPPING AROUND THE BUMPER.
2. Any loose, protruding, or damaged parts such as hoods,
doors, fenders, trim, etc. should be secured or removed
prior to moving the vehicle.

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.
