Caution
1. If steering movements are made when driving at high speed, or when driving on road surfaces
with low frictional resistance, or when passing over bumps, the ABS may operate even though
sudden braking is not being applied. Because of this, when getting information from the customer,
check if the problem occurred while driving under such conditions as these.
2. During ABS operation, the brake pedal may vibrate or may not be able to be depressed. Such
phenomena are due to intermittent changes in hydraulic pressure inside the brake line to prevent
the wheels from locking and is not an abnormality.

BODY ± Window Glass42-13
HANDLING OF AUTO WINDOW SEALER
Keep the sealant in a cool place, not exposed to the direct
rays of the sun. Do not place any heavy article on the sealant
nor press it, otherwise it will become deformed. Avoid storing
the sealant for more than 6 months, because it will lose its
sealing effect.
BODY PINCH-WELD FLANGE SERVICING.
Before servicing the body pinch-weld flange, remove old
adhesive completely. If the flange requires painting, bake
it after painting is completed.
WORKING PROCESS
Window glass installation procedure
Body side
Cleaning of adhesion surface
Cut off the residual adhesive until the
thickness is less than 2 mm. Clean the
adhesion surface with isopropyl alcohol,
and let dry for 3 minutes or more.
Attaching of spacer and dual lock
fastener
Attach the spacer and dual lock fastener
to set the positions for the glass to be
installed.
Application of primer
Apply to the adhesion surface of the
body and let dry for 3 minutes or more.
Window glass side
Reusing the glassReplacing the glass
Cleaning of adhesion surface
Competely cut off all of the residual
adhesive. Clean the adhesion surface
with isopropyl alcohol, and let dry for
3 minutes or more.Cleaning of adhesion surface
Clean off any dirt adhering to the adhe-
sion surface with isopropyl alcohol, and
let dry for 3 minutes or more.
Gluing window spacer and dual lock fastener
Glue the window spacer and dual lock fastener to the glass, following the standard position
all the way around the inside edge of the glass.
Application of primer
Apply sufficient primer evenly to the adhesion surface so that there is no patchiness. After
application, let dry for 3 to 30 minutes.
Application of adhesive
Within 30 minutes after applying the primer, apply the adhesive evenly all the way around
the inside edge of the glass.
Installing the glass
After applying the adhesive, lightly press the glass evenly so that it adheres
completely.
Cleaning
After removing any adhesive that is sticking out or adhering to the body or
glass with a spatula, ect., clean off with isopropyl alcohol.
Checking for water leaks
Carry out a shower test to check that no water will leak through.
