GENERAL Precautions before Service . .
Caution
1.Before connecting or disconnecting the negative
be sure to turn off the ignition and
the lighting switch.
(if this is not done, the possibility semi-
conductor parts being damaged.)
2.After completion of the work steps [when the bat-
tery’s negative terminal is connected], warm
up the engine and allow it for approximately
five minutes under the conditions be-
low, in order to stabilize the engine condi-
tions, and then check to be sure that idling’ is
satisfactory.

VEHICLE WASHING
If high-pressure car-washing equipment or steam car -washing
equipment is used to wash the vehicle, be maintain
the spray nozzle at a distance of at ‘least 300 mm (12 in.)
from any plastic parts and all opening parts (doors , luggage
compartment, etc.).
APPLYING ANTI-CORROSION
OTHER UNDERCOAT AGENTS.,
Be careful not to adhere oil or grease to the heate d oxygen
sensor. If adhered, the sensor may malfunction.
Protect the heated oxygen sensor with a cover befor e applying
anti-corrosion agent, etc.
SCAN TOOL
To operate the scan tool, refer to the “MUT-II OPER ATING
INSTRUCTIONS”.
Caution
Turn the ignition switch off befoie connecting and discon-
necting the scan tool.

GENERAL Maintenance
4.Before removing dipstick, wipe all dirt from area around
dipstick. Then take out the dipstick and check the condition
of the fluid.
Further investigation of the transaxle is necessary if,
l the fluid smells burnt.
l the fluid color is brown or black.
l metal particles can be seen or felt on the dipstick .
5.Check to see if fluid level is in “HOT” range on dipstick.
If fluid level is low, add ATF until level reaches “HOT”
range. Low fluid level can cause a variety of condi tions
because it allows pump to take in air along with fl uid.
Air trapped in hydraulic circuit forms bubbles which make
fluid spongy.
Therefore, pressures will be erratic. Improper filling can also raise fluid level too hig h. When
transaxle has too much fluid, gears churn up foam a nd
cause same conditions which occur with low fluid le vel,
resulting in accelerated deterioration of ATF.
In either case, air bubbles can cause overheating, fluid
-oxidation, which can interfere with normal valve, clutch,
and servo operation. Foaming can also result in flu id
escaping from transaxle vent where it may be mistak en
for a leak.
6. Be sure to examine fluid on dipstick closely.

2.Check the wheel cylinder boots for evidence, a’ brake
fluid leak. Visually check the
boots for tears or
cracks. (A slight amount of fluid on the boot may not
be a leak, but may be preservative assembly.)
Caution
The shoes for the right and left be,
replaced at the same time.
Never split or intermix brake
sets.
All four shoes must be replaced as a set.
Thickness of lining
Limit: 1.0 mm in.)
17. BRAKE HOSES (Check for
leaks)
Check of brake hoses and tubing should be
brake service operations.
The hoses should be checked for:
1.Correct length, severe surface cracking, pulling, scuffing
or worn spots. (If the fabric casing of the hoses i s exposed
by cracks of abrasion in the rubber hose cover, the hoses
should be replaced. Eventual deterioration of may
occur with possible bursting failure.)
2. Faulty installation, casing twisting or interfer ence
wheel,’ tire or chassis.
18. BALL JOINT AND STEERING SEALS
(Check for grease leaks damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic lubrication. Damaged
seals and boots should be replaced to prevent leakage
or contamination of the grease.
2.Check the dust cover and boots for proper sealing, leakage
and damage. Replace them if defective.
19. DRIVE SHAFT BOOTS (Check for leaks
and damage)
1. These components, which are permanently lubricat ed
at the factory, do not require periodic Damaged
boots should be replaced to prevent leakage or contamina-
tion of the grease.
2.Check the boots for proper sealing, leakage and damage.
Replace it if defective.
AXLE OIL (Check oil level)-AWD
Remove the filler plug and check the oil level at bottom of
filler hole. If the oil level is slightly below the filler hole, it
is in satisfactory condition.
