< PRECAUTION >
PRECAUTIONS
• To reinstall the rubber hose securely, make sure that hose insertionlength and orientation is correct. (If tube is equipped with hose
stopper, insert rubber hose into tube until it butts up against hose
stopper.)
HOSE CLAMPING
• If old rubber hose is re-used, install hose clamp in its original posi-tion (at the indentation where the old clamp was). If there is a trace
of tube bulging left on the old rubber hose, align rubber hose at
that position.
• Discard old clamps; replace with new ones.
• After installing plate clamps, apply force to them in the direction of the arrow, tightening rubber hose equally all around.
Engine OilsINFOID:0000000001539215
Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin contact
with used oil.
If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.
HEALTH PROTECTION PRECAUTIONS
• Avoid prolonged and repeated contact with oils, particularly used engine oils.
• Wear protective clothing, including impervious gloves where practicable.
• Do not put oily rags in pockets.
• Avoid contaminating clothes, pa rticularly underpants, with oil.
• Heavily soiled clothing and oil-impregnated footwear should not be worn. Overalls must be cleaned regu- larly.
• First aid treatment should be obtained immediately for open cuts and wounds.
• Use barrier creams, applying them before each work period, to help the removal of oil from the skin.
• Wash with soap and water to ensure all oil is removed (skin cleansers and nail brushes will help). Prepara-
tions containing lanolin replace the natural skin oils which have been removed.
• Do not use gasoline, kerosene, diesel fuel, gas oil, thinners or solvents for cleaning skin.
• If skin disorders develop, obtain medical advice without delay.
• Where practical, degrease components prior to handling.
• Where there is a risk of eye contact, eye protection should be worn, for example, chemical goggles or face
shields; in addition an eye wash facility should be provided.

SEAT BELTS
4. Check the shoulder seat belt guide and shoulder belt height adjuster for\
front seats. Ensure guide swivelsfreely and that belt lays flat and does not bind in guide. Ensure height adjuster operates properly and
holds securely.
5. Check retractor operation:
a. Fully extend the seat belt webbing and check for twists, tears or other damage.
b. Allow the seat belt to retract. Ensure that belt retu rns smoothly and completely into the retractor. If the
seat belt does not return smoothly, wipe the inside of the loops with a clean paper cloth, because dirt built
up in the loops of the upper anchors can c ause the seat belts to retract slowly.
c. Fasten the seat belt. Check the seat belt returns smoothly and completely to the retractor. If the belt does not return smoothly, the cause may be an accumulati on of dust or dirt. Use the “SEAT BELT TAPE SET”
and perform the following steps.
Inspect the front seat belt through-anchor:1. Pull the seat belt out to a length of 500 mm (19.69 in) or more.
2. Use a clip or other device to hold the seat belt at the center pillar belt opening.
3. Pass a thin wire through the through-anchor belt opening. Hold both ends of the wire and pull taut while moving it up and down several times along the belt opening surface to remove dirt.
4. Any dirt that cannot be removed with the wir e can be removed by cleaning the opening with a clean
cloth.
5. Apply tape at the point where the belt contacts the through-anchor belt opening.
NOTE:
Apply the tape so that there is no looseness or wrinkling.
6. Remove the clip holding the seat belt and check that the belt returns smoothly.
7. Repeat steps above as necessary to check the other seat belts.
SEAT BELT RETRACTOR ON-VEHICLE CHECK
Emergency Locking Retractors (ELR) and Automatic Locking Retractors (ALR)
NOTE:
All seat belt retractors are of the Emergency Locking Retractors (ELR) type. In an emergency (sudden stop)
the retractor will lock and prevent the belt from ext ending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automati c Locking Retractors (ALR) mode. The ALR mode (also
called child restraint mode) is used when installing child seats. The ALR mode is activated when the seat belt
is fully extended. When the belt is then retracted partiall y, the ALR mode automatically locks the seat belt in a
specific position so the belt cannot be extended any furt her. To cancel the ALR mode, allow the seat belt to
fully wind back into the retractor.
Check the seat belt retractors using the following test(s ) to determine if a seat belt retractor and belt assembly
is operating properly.
ELR Function Stationary Check
Grasp the shoulder belt and pull forward quickly. The re tractor should lock and prevent the belt from extending
further.
ALR Function Stationary Check
1. Pull out entire length of seat belt from retractor until a click is heard.
2. Retract the belt partially. A clicking noise should be hear d as the belt retracts indicating that the retractor is
in the Automatic Locking Retractor (ALR) mode.
3. Grasp the seat belt and try to pull out the retractor. The belt must lock and not extend any further. If neces-
sary replace the seat belt retractor and belt assembly.
4. Allow the entire length of the belt to re tract to cancel the automatic locking mode.
ELR Function Moving Check
WARNING:
Perform the following test in a safe, open area clear of other vehicles and obstructions (for example, a
large, empty parking lot). Road surface must be p aved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highw ays. This could result in an accident and serious
personal injury. The driver and passenger must be prepared to brace themselves in the event the
retractor does not lock.
1. Fasten drivers seat belt. Buckle a passenger in to the seat for the belt that is to be tested.

STEERING COLUMN
1. Check the column bearings for damage or unevenness. Lubricate with recommended multi-purposegrease. Replace the steering column as an assembly, if necessary.
2. Check the column tube for deformation or breakage. R eplace the steering column as an assembly, if nec-
essary.
3. If the vehicle has been involved in a collision, or if noise and rat- tles are heard during a turn, check the length "L" of the column.
If out of specification, replace the steering column as an assem-
bly.
4. Check for proper lubrication, apply grease as necessary.
5. Check for wear around the seal edges, replace the steering col- umn as an assembly as necessary.
6. Check for corrosion or pitting around the seal sliding area.
7. Replace the seal and shaft in case of seal edge wear or damage.
8. After installing the steering column, check the tilt mechanism for proper operation.
CAUTION:
• Do not exert any load in the axial direction immediately before or after column removal.
• After installation, check smooth steering wh eel rotation, without any catches or noise.
