PROCEDURE

1. INSTALL ULTRASONIC SENSOR CUSHION SET

HINT:

Perform this procedure only when replacement of the ultrasonic sensor cushion set is necessary.

2. INSTALL FRONT SIDE ULTRASONIC SENSOR RETAINER (w/ Advanced Park)

HINT:

	Cleaning Area		Primer

(1) Clean the surface of the front bumper assembly.

1. Remove any remaining double-sided tape from the front bumper assembly.

NOTICE:

Installing the front side ultrasonic sensor retainer with some double-sided tape remaining may cause poor adhesion. Perform this procedure until the tape is sufficiently removed.
Make sure to use a cloth when removing. Using a screwdriver, etc., may cause damage and poor adhesion.

2. Wipe off any adhesive residue with cleaner.

(2) Cover the sensor installation hole with a 25 mm (0.984 in.) circular piece of tape.

NOTICE:

If the primer contacts a painted surface, it may leave light primer marks. Therefore, use protective tape when using liquid primer.

(3) Apply primer to the installation area of the front side ultrasonic sensor retainer on the front bumper assembly.

1. Using a brush or felt, apply primer or equivalent to the front side ultrasonic sensor retainer installation area.

NOTICE:

Replace the brush or felt if it is dirty or has become hardened.
Do not apply primer to the painted side.
Do not touch the front bumper assembly until the primer has dried.

2. Let the primer dry sufficiently.

NOTICE:

Do not touch applied surfaces until the primer is dry.

Recommended drying time:

10 minutes or more (at 23°C (73°F))

3. Confirm that the primer has completely dried by touching the front bumper assembly. Then remove the tape.
