INSTALLATION

PROCEDURE

1. INSTALL ULTRASONIC SENSOR CUSHION SET

HINT:

Only perform this procedure when removing and installing the ultrasonic sensor cushion set.

(a) Install the ultrasonic sensor cushion set as shown in the illustration.

Install in this Direction

2. INSTALL REAR CENTER ULTRASONIC SENSOR RETAINER

NOTICE:

Installing the rear center 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.

HINT:

Perform the following procedure only when replacement of a rear center ultrasonic sensor retainer is necessary.
Use the same procedure for the RH and LH side.
The following procedure is for the LH side.

(a) Clean the rear bumper assembly surface.

(1) Remove any remaining double-sided tape from the rear bumper assembly.

(2) Wipe off any tape adhesive residue with cleaner.

(b) Cover the sensor installation hole from the outside of the rear bumper cover with a 30 mm (1.18 in.) square piece of tape.

*a	30 mm (1.18 in.)

(c) Apply primer to the rear bumper assembly on the installation area of the rear center ultrasonic sensor retainer using a brush or felt.

NOTICE:

Replace the brush or felt if it is dirty or has become hardened.
Keep any painted surface free from primer.
If the primer contacts a painted surface, it may leave light primer marks. Therefore, use protective tape when using liquid primer.
Do not touch surfaces to which primer has been applied until the rear center ultrasonic sensor retainer has been attached.

(d) 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))

(e) Confirm that the primer has completely dried by touching the rear bumper assembly. Then remove the tape.

(f) Remove the peeling paper of the new rear center ultrasonic sensor retainer trying not to touch the adhesional surface.

NOTICE:

After removing the peeling paper, do not touch the surface of the tape with your fingers or cotton work glove.

(g) Align the rear center ultrasonic sensor retainer with the scribed line on the rear bumper assembly and install it as shown in the illustration.

NOTICE:

The application strength of the rear center ultrasonic sensor retainer will weaken if reapplied. If reapplication is necessary, be sure to replace it with a new one.

HINT:

Apply pressure so that it does not lift up from the rear bumper assembly.
Pushing force: 50 N (5.1 kgf) for 3 seconds
