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”.

ReartAWD>I
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.

FUEL HOSES (Check for leaks or
damagekOOSnOB.
1.Check for damage or leakage in the fuel lines and con-
nections and looseness of the fuel tank filler tube cap.
2. Inspect the surface of fuel hoses for heat and mecha-
nicall damage. Hard and brittle rubber, cracking, check-
ing, tears, cuts, abrasions and excessive swelling
indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by cracks and abrasions in the fuel system, the hoses
should be changed.
3. AIR CLEANER ELEMENT (Replace)
MMlSAKH
The air cleaner element will become dirty and loaded with dust during use, and the filtering effect will be substantiallyreduced. Replace it with a new one.

(1) Loosen the clamp coupling the air intake hose and the air cleaner cover, and separate the hose.
(2) Disconnect the volume air flow sensor connectors.
(3) Unclamp the air cleaner cover clip.
(4) Lifting the air intake hose, remove the air cleaner cover.

momentarily to each position, ending in “N” Neutral
position.
(11)Add sufficient ATF to bring fluid level to lower mark.
Recheck fluid level after transaxle is at normal Operating
temperature. Fluid level should be between upper and lower marks of
“HOT” range, Insert dipstick fully to prevent dirt from
entering transaxle.

COOLANT (Change)MOOSEEAC
Check the cooling system parts, such as radiator, heater,
and oil cooler hoses, thermostat and connections for
leakage and damage.
CHANGE COOLANT
1. Remove the radiator cap.
2. Loosen the drain plug to drain the coolant.
3. Drain the coolant from the reserve tank.
4. After draining the coolant, tighten the drain plug securely.
5.Supply the coolant into the radiator until it is filled up to
its filler neck.
6. Supply the coolant into the reserve tank.
7. After warming the engine until the thermostat opens, remove the radiator cap and check the coolant level.
8.Supply the coolant into the radiator until it is filled up to
its filler neck, and install the radiator cap securely.
9.Fill the reserve tank with coolant up to the “FULL” line.

Check for fluid contamination and wear. Replace complete
set of pads if defective.
Caution
The pads for the right and left wheels should be
reDlaced at the same time. Never “split” or intermix
brkke pad sets.
All four pads must be replace as a complete set.

1. Remove the brake drum and check the thickness of brake shoe lining for wear. Check the automatic brake
adjusting system by hand to see if it operates smoothly.
Also see if the gears are in proper mesh with each
other. To assure smooth functioning, apply a very thin
coat of multipurpose grease to the friction surface of
adjuster and link shaft.

13-82 FUEL SYSTEM -On-Vehicule Inspection of MFI Components
OPERATION
l The power-steering pressure switch functions
to convert data as to whether there is or is not apower steering load to LOW-or HIGH-level vol-
tage, and the resulting signals are input to the engine control module. The engine control mod-
ule, based upon those signals, regulates the
idle-speed control motor. l The battery voltage within the engine control
module is applied, by way of the resistance, to
the power-steering pressure switch. When
steering maneuvers are made, the pressure of
the power-steering oil increases, thus switching
ON the power-steering pressure switch, with
the result that the current is grounded. As a re-
sult, the power-steering pressure switch vol-
tage changes from HIGH level to LOW level.
