 Notes to assembly and handling
Check: As soon as you receive this product, confirm that it is not damaged and that all the accessories are included.
Caution: Replace with this product at a special maintenance factory.
Caution: When assembling this product, be sure to follow the repair book of your car (issued by Toyota Motor Corp.)
and the precautions appearing in this document.
Warning: Before attachment, stop your car at a flat place, turn the engine OFF, and set the parking brake. If you work at
an unstable place or do not set the parking brake, a serious accident may occur.
Warning: When you work near the engine compartment or muffler, take care not to suffer from a burn or serious injury.
Warning: Neither modify this product nor attach it to cars other than the applicable models, otherwise a fracture or
accident may occur.
Caution: This product conforms to the structural standards, so an official inspection can be conducted as usual except
when you attach it to cars other than the applicable models or modify any other parts.
Check: This product can be attached to the applicable cars if they have not encountered any accident in the past.
Caution: The uncoated product (MS343-18002-00) requires coating to be consistent with the exterior color of your car.
If you use forced drying, fix the product without deformation and dry it at less than 70°C.
Caution: If you degrease the uncoated product before coating, use IPA or white gasoline rather than Silicon Off or
thinner.
Caution: During baking, take great care not to increase the temperature to more than 70°C, otherwise the product may
be deformed or cracked.
Caution: Do not remove any car parts except the ones indicated in this document.
Caution: When you remove car parts, keep clips in order to prevent them from being lost or from being confused
during replacement.
Caution: Be sure to prepare a protection sheet and work on it in order to prevent a rear bumper spoiler from being
scratched during attachment.
In addition, take great care not to damage any car parts during assembly.
Caution: The bonding strength of double-sided adhesive tape reduces at outdoor temperatures of less than 15°C. In this
case, use a dryer to heat the tape and contact surface until the temperature is about 40°C.
Warning: Securely tighten the bolts at given torque. Insufficient torque causes them to become loose with time and
eventually come off, resulting in a serious accident or failure.
Warning: The bolts are apt to be loose for a while after attachment, so tighten them further after your car travels several
kilometers.
Warning: Check whether this product interferes with any other parts after the attachment. If you find any interference,
contact your dealer. Running your car as is could cause a fracture or failure.
Warning: If a strong shock such as a collision is given to the product after assembly, it or its joint may be deformed,
broken, or fail. In this case, immediately stop using the product.
Warning: If you feel abnormal shaking or noises during traveling, immediately park your car at a safe place and ask a
maintenance factory to conduct an inspection.
Driving your car as is could cause a fracture or accident.
Warning: This product is designed to be used with cars traveling on paved roads. Do not run it on an unimproved or
snow-covered road, otherwise the product may be broken.
Warning: This product has sufficient strength and durability, but it may be broken or fail under certain keeping,
handling, or running conditions. Pay great attention to storage, attachment, and usage.
Caution: Do not use any organic solvents, such as thinner and gasoline, for maintenance because they may cause
discoloration or deformation.
Caution: If you damage your car or this product during assembly or running, we will not accept any complaint.
Be sure to follow the precautions mentioned above and the assembling procedures shown in this document.
These assembling and handling procedures display the following symbols to show precautions the
user shall follow for safe use.
Warning
If you attach or handle the product wrongly without following this
warning, you may be killed or seriously injured.
Caution
If you attach or handle the product wrongly without following this
caution, you may be disabled or the product may be physically damaged.

 How to assemble the uncoated product
This document describes work before and after coating necessary for the uncoated product
(MS343-18002-00). Follow the procedures shown below.
 Coating the real bumper spoiler
1. Coat the real bumper spoiler 1) and the tow
hook cover 12) as shown in Figure 1.
Caution: For degreasing, use IPA or white
gasoline rather than Silicon Off
or thinner, otherwise the
surfacer may melt.
Caution: Do not coat the molding contact
surface and double-sided
adhesive tape, otherwise the
bonding strength may decrease.
To a d d r e s s t h i s p r o b l e m, u s e
masking tape in the coating
process.
Caution: Take great care not to increase
the baking temperature to more
than 70°
°°°C in the coating process,
otherwise the product may be
deformed or cracked.
If you use forced drying, fix the
product without deformation.

 Attaching the molding
1. As shown in Figure 3, clean up the molding
contact surface, degrease it with IPA or white
gasoline by means of one-way wiping, and
apply the PAC primer K-500 13) to it.
Caution: Do not use solvents other than
those mentioned above for
degreasing, otherwise the
remaining fat may cause the
tape to come off. In addition,
take care not to spill out the
primer, otherwise it may cause a
stain.
Advice: Dry the product for more than 10
minutes after each of the
degreasing and primer applying
processes.

2. As shown in Figure 4, put the moldings 10) and
11) to the rear bumper spoiler 1) while
removing the separator from the double-sided
tape, and press the former at a force of at least
49 N (5 kgf).
The moldings are redundant, so cut them to
appropriate length with scissors.
Caution: The molding 10) has two colors.
Select one suitable to the paint
color.
Caution: The bonding strength of
double-sided adhesive tape
reduces at outdoor temperatures
of less than 15°
°°°C. In this case,
use a dryer to heat the tape
surface until the temperature is
about 40°
°°°C.
3. Attach the coated tow hook cover 12) to the
rear bumper spoiler 1) as shown in Figure 4
while inserting the strap for removal protection
into the latter.

13. As shown in Figure 11, clean up the surface of
the rear bumper that makes contact with the
rear bumper spoiler 1) and the rubber washer
5), degrease them with IPA or white gasoline
by means of one-way wiping, and bond the
washer (1 place in the right and left hands).
Degrease the hatched area—grained part of
your car—with IPA or white gasoline by means
of one-way wiping and apply the PAC primer
K-500 7) to it.
Warning: If an additional coat is given to
the your car, be sure to use a
compound to remove it while
taking care not to damage the
main coat, and then degrease it.
Caution: Carry out degreasing operation
with IPA or white gasoline
rather than a parts cleaner,
because the latter does not
remove fat, resulting in removal
of the tape. In addition, take
care not to spill out the primer,
otherwise it may cause a stain.
Advice: Dry the product for more than 10
minutes after each of the
degreasing and primer applying
processes.
14. As shown in Figure 11, remove the separator
from the double-side tape of the rear bumper
spoiler 1) about 30 mm outside from the center
and put the removed separator to the front
surface with masking tape.
(6 places in each of RH and LH)
Caution: Completely removing the
separator from the tape makes it
difficult to attach the product to
the correct position.
 Assembling procedures
1. Cover the rear bumper with the rear bumper
spoiler 1) and fix both with the clip 2).
(2 places in each of RH and LH)

(2 places in each of RH and LH)
3. See Figure 15 to make the rear bumper spoiler
1) flush with the height mark and press it while
removing the separator from the double-sided
tape (6 places in each of the right and left
hands) in the order shown in the figure. Note
that the pressing force shall be at least 49 N (5
kgf).
Caution: The bonding strength of
double-sided adhesive tape
reduces at outdoor temperatures
of less than 15°
°°°C. In this case,
use a dryer to heat the tape
surface until the temperature is
about 40°
°°°C.
Caution: Remove the separator from the
double-sided tape while taking
care not to cut off the former.
Caution: If you do not follow the separator
removing order, a gap may be
produced.
Caution: Press the double-sided tape
sufficiently, otherwise it may lift
or come off.
Caution: Do not wash your car within 24
hours after you bond the
double-sided tape.
4. Fix the rear bumper spoiler 1) securely by
further tightening the tapping screw 3) fastened
temporarily.
