2.
Note the following before proceeding with work on the
electrical system. Note that the following must never be done:Unauthorized modifications of any electrical device or
wiring, because such modifications might lead to a vehicle malfunction, over-capacity or short-circuit that could resultin a fire in the vehicle.
When servicing the electrical system, disconnect the negative cable terminal from the battery.

00-l 6GENERAL - Precautions before Service
Caution
1. Before connecting or disconnecting the negative
cable, be sure to turn off the ignition switch and the
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:
85-95X (185-203°F)
Lights, electric fans, accessories: OFF
Transaxle: neutral position (A/T models: “N” or
“P”)
Steering wheel:neutral (center) position

VEHICLE WASHING
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 300 mm (12 in.) from any plastic parts and all opening parts (doors, luggage compart-
ment, etc.).
SCAN TOOL (1) To operate the scan tool, refer to the “Scan Tool Operation Instructions”.
Connection and disconnection of the scan tool should
always be made with the ignition switch in the OFF
position.
(2) Always use a ROM pack that is appropriate for the vehicle.

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
When a locked vehicle must be towed and keys are not available, the vehicle may be lifted and towed from the front.provided the parking brake is released. If not released, the rear
wheels should be placed on a tow dolly.

00-l 8GENERAL - Towing and Hoisting
SAFETY PRECAUTIONS
The following precautions should be taken when towing thevehicle.
1.DO NOT LIFT OR TOW THE VEHICLE BY ATTACHING TO
OR WRAPPING AROUND THE BUMPER.
2. Any loose or protruding parts of damaged vehicle such as hoods, doors, fenders, trim, etc., should be secured prior to
moving the vehicle.
3.Operator should refrain from going under a vehicle while it
is lifted by the towing equipment, unless the vehicle in
adequately supported by satefy stands.
4. Never allow passengers to ride in a towed vehicle. 5. State and local rules and regulations must be followed when towing a vehicle.

Refer to the section “Special Handling Instructions for AWD
Models”.

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

SPEEDOMETER TEST
IF A FREE ROLLER IS USED
1.Set the free roller on the floor (at the rear wheels) so that it
is aligned with the vehicle’s wheelbase and the rear tread.
2.Carefully move the vehicle onto the tester and free roller.
3. Set the speedometer tester in place.
4. Perform the speedometer test. For information concerning the measurement of speed and
the allowable error, refer to GROUP
54-Meters and
Gauges.
Caution
Do not operate the clutch suddenly, or increase or
reduce speed suddenly during the work.
IF THE REAR WHEELS ARE JACKED UP
1. Move the vehicle onto the speedometer tester.
2. Jack up the rear wheels, and place axle stands at the designated part of the side sill.
3. Perform the speedometer test. For information concerning the measurement of speed and
the allowable error, refer to GROUP
54-Meters and
Gauges.
Caution
Do not operate the clutch suddenly, or increase or
reduce speed suddenly during the work.
Front wheel side slip
To prevent the front wheels from moving from side to side, attach tension bars to the towing hooks, and secure both ends
at anchor plates.
Accident prevention procedures (1) Attach a chain or wire to the rear traction hook. Make sure the end of the wire or chain is secured firmly.
(2) Take all other necessary precautions.
BRAKE TEST In order to stabilize the viscous coupling’s dragging force, the
brake test should always be conducted after the speedometer
test.
FRONT WHEEL MEASUREMENTS
1. Place the front wheels on the brake tester.
2. Perform the brake test.
Caution
The rear wheels should remain on the ground.
3. If the brake dragging force exceeds the specified value, jack up the vehicle and manually rotate each wheel tocheck the rotation condition of each wheel.
NOTE
If the brake dragging force exceeds the specified value, the
cause may be the effect of the viscous coupling’s dragging
force, so jack up the front wheels and check the rotation condition of the wheels in this state for no effect by the
viscous coupling’s dragging force.

2. Release the parking brake.
3. Rotate each wheel manually and check to be sure
that there is no dragging.
3. Use the engine to drive the tires, and then make the measurement.
Caution
1.If an error is indicated in the state of engine drive,
motor drive can be used concurrently.
2.Do not operate the clutch suddenly, or increase or
reduce speed suddenly during the work.
REAR WHEEL MEASUREMENTS
1. Jack up the front wheels, and place an axle stand at the
designated part of the side sill.
2. Jack up the rear wheels, and then, after setting a pick-up stand and balancing machine in place, follow the same
procedure as for front wheel measurements.
