FRONT SEAT BELT

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 wire 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 extending any further. All 3-point type seat belt retractors
except the driver's seat belt also have an Automatic 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 partially, the ALR mode automatically locks the seat belt in a
specific position so the belt cannot be extended any further. 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 retractor assembly is operating prop-
erly.

ELR Function Stationary Check

Grasp the shoulder belt and pull forward quickly. The retractor 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 heard 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 retractor assembly.

4.

Allow the entire length of the belt to retract 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 paved and dry. DO NOT perform the following test on
wet or gravel roads or on public streets and highways. 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 into the seat for the belt that is to be tested.

2.

Proceed to the designated safe area.

3.

Drive the vehicle at approximately 16 km/h (10 MPH). Notify any passengers of a pending sudden stop.
The driver and passenger must be prepared to brace themselves in the event the retractor does not lock.
Apply brakes firmly and make a very hard stop.

During stop, seat belts should lock and not be extended. If the seat belt retractor assembly does not lock, per-
form the retractor off-vehicle check.

SEAT BELT RETRACTOR OFF-VEHICLE CHECK

1.

Remove the seat belt retractor assembly.

2.

Slowly pull out belt while tilting the retractor assembly forward from the mounted position without twisting
the retractor assembly as shown in the illustration.
