identified by the model codes, or similar designation
(engine type, transaxle type, etc.). A description of
these designations is covered in this unit under “VEHICLE IDENTIFICATION”.
SERVICE ADJUSTMENT PROCEDURES
“Service Adjustment Procedures” are procedures
for performing inspections and adjustments of
particularly important locations with regard to the
construction and for maintenance and servicing, but
other inspections (for looseness, play, cracking,
damage, etc.) must also be performed.

only; a troubleshooting guide is prepared for each
appropriate group. Indicates the value used as the standard for judging
the quality of a part or assembly on inspectian or the
value to which the part or assembly is corrected and
adjusted. It is given by tolerance.
LIMIT
Shows the standard for judging the quality of a part
or assembly on inspection and means the maximum
or minimum value within which the part or assembly must be kept functionally or in strength. It is a value
established outside the range of standard value.
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).
CAUTION

lighting switch.
(If this is not done,there is the possibility of
semiconductor parts being damaged.)
2.For MFI-equipped models, after completion of the
work steps [when the battery’s negative (-) termi-
nal is connected], warm up the engine and allow it
to idle for approximately five minutes under the
conditions described below, in order to stabilize
engine control conditions, and then check to be
sure that the idling is satisfactory.
Engine coolant temperature:

WRECKER TOWING RECOMMENDATION

FRONT TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-type
equipment to prevent the bumper from deformation.
If this vehicle is towed, use wheel lift or flat bed
equipment.
The vehicle may be towed on its rear wheels for extended
distances provided the parking brake is released. It is recom-
mended that vehicles be towed using the front pickup
whenever possible.
REAR TOWING PICKUP
Caution
This vehicle cannot be towed by a wrecker using sling-type
equipment to prevent the axle beam from deformation. If this vehicle is towed, use wheel lift or flat bed
equipment.
Manual transaxle vehicles may be towed on the front wheels,
provided the transaxle is in neutral and the drive-line has not
been damaged. The steering wheel must be clamped in the
straight-ahead position with a steering wheel clamping device
designed for towing service use.
Caution
Do not use steering column lock to secure front wheel
position for towing.
Automatic transaxle vehicle may be towed on the front wheels at speeds not to exceed
50 km/h (30 mob) for a distances not
to exceed 30 km (18 miles).
Caution
If these limits cannot be met, the front wheels must be
placed on a tow dolly.
TOWING WHEN KEYS ARE NOT AVAILABLE

HOISTING
POST TYPE
Special care should be taken when raising the vehicle on a
frame contact type hoist. The hoist must be equipped with the
proper adapters in order to support the vehicle at the proper
locations.
Caution
When service procedures require removing rear suspen-
sion, fuel tank, spare tire and lift gate, place additional
weight on rear end of vehicle or anchor vehicle to hoist to
prevent tipping of center of gravity changes.
FLOOR JACK
The usual type of floor jack is used at the following locations.
Front:
Under the mid point of centermember
tAWD> Under the mid point of crossmember
Rear:
Under the jack up bracket of rear floor pan
Under the rear differential
Cautions
1. Never use a jack at the lateral rod or rear suspension
assembly.
2.In order to prevent scarring the centermember
or crossmember ,
place a piece of cloth on the
jack’s contact surface (to prevent corrosion caused by
damage to the coating).
3. A floor jack must never be used on any part of the
underbody.
4.Do not attempt to raise one entire side of the vehicle by
placing a jack midway between front and rear wheels.
This practice may result in permanent damage to the
body.

Towing methods
If a tow truck is used Lifting method for 4 wheels-Good Remarks
l For AWD models, the basic principle is that
all four wheels are to be raised before
towing.
l The shift lever should be set to 1
st gear and
the parking brake should be applied. >
l The selector lever should be set to “P” position and the parking brake should be
applied.

OOA0032
Front wheels lifted-No good l The vehicle must not be towed by placing
only its front wheels or only the rear wheels
on a rolling dolly, because to do so willresult in deterioration of the viscous
coupling and result in the viscous coupling
causing the vehicle to jump forward
suddenly.
OOA0034
Front wheels lifted-No good l
If only the front wheels or only the rear
wheels are lifted for towing, the bumper
will be damaged. In addition, lifting of the rear wheels causes
the oil to flow forward, and may result in
heat damage to the rear bushing of the
transfer, and so should never be done.
Rear wheels lifted-No good
