2. INSTALL FRONT CORNER ULTRASONIC SENSOR RETAINER (except Sport Package)

NOTICE:

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

HINT:

Use the same procedure for both front corner ultrasonic sensor retainers.

(a) Clean the front bumper cover surface.

(1) Remove the double-sided tape from the front bumper cover.

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

(b) Cover the sensor installation hole form the outside of the bumper cover with a 23 mm (0.91 in.) square piece of tape.

23 mm (0.91 in.)

(c) Using a brush or felt, apply primer or equivalent to the front corner ultrasonic sensor retainer installation area.

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 front corner ultrasonic sensor retainer has been attached.

Primer

HINT:

Primer application outside of the scribed line is acceptable.

(d) Let the primer dry sufficiently.

NOTICE:

Do not touch applied surfaces until the primer is dried.

Recommended drying time:

10 minutes or more (23°C (73°F))

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

(f) Remove the peeling paper of a new front corner ultrasonic sensor retainer trying not to touch the adhesion surface.

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

NOTICE:

  • The application strength of the front corner ultrasonic sensor retainer will weaken if reapplied. If reapplication is necessary, be sure to replace it with a new one.
  • Check that the retainer scribed lines on the both sides are positioned inside the front bumper scribed line.
  • Check that the end of the retainer scribed lines on both sides is within the permissible range between the upper and lower lines of the scribed line.
  • Check that the four corners of the retainer rib are positioned within the scribed lines on the front bumper.

HINT:
