16.HANDLING PRECAUTIONS FOR SILICON-CONTAINING SPRAY
When a silicone contained in the lubricant, rust inhibitor or glazing agent adheres to the electrical contact of
the relay or switch, nonconducting silica dioxide (SiO
2
) film will be formed, which may lead to poor continuity.
Therefore, the following precautions must be observed when using the silicon-containing spray.
• Never spray directly to the electrical equipment.
• When using the spray close to the electrical equipment, always put the cover on it. Be sure to put the cover
on the electrical equipment especially when using the spray to the locations shown in the figure below and
their surrounding areas.
• If the residual silicon remains in the vicinity of the electrical equipment after the spray has been used, the
vaporized silicon stands around the electrical equipment and it may adhere to electrical contact. After using
the spray, be sure to wipe the silicon off with a cloth.
• Even when using the spray to the place away from the electrical equipment, the droplet of the spray may
be splashed to the periphery. Use as small amount of spray as possible, and take care not to splash the sil-
icon to the periphery.
NOTE:
The “silicon” used in this section refers to “silicone”, that is, silicon polymer.

A: NOTE
This information will improve the efficiency of main-
tenance and assure the sound work.
1. CLEANING
• Perform the operation in a clean location and use
extra caution in dust proofing.
• Clean the items (except for assembly compo-
nents) with steam, etc. before disassembly. During
steam cleaning, wrap the air breather, oil level
gauge, connectors, etc. with vinyl tape to prevent
steam from entering inside the parts.
• For cleaning solution, use an appropriate new
cleaning solvent, etc.
• Do not clean rubber parts such as O-ring, gasket
and oil seal with cleaning solution.
2. FASTENERS NOTICE
Fasteners are used to prevent the parts from dam-
age, dislocation and play due to looseness. Fasten-
ers must be tightened to the specified torque. Do
not apply paint, lubricant, rust retardant or other
substance to the surface around bolts, nuts, etc.
Doing so will make it difficult to obtain the correct
torque and result in looseness and other problem.
3. STATIC ELECTRICITY DAMAGE
Do not touch the control modules, connectors, logic
boards and other such parts when there is a risk of
static electricity. Always use a static electricity pre-
vention cord or touch grounded metal for the elimi-
nation of static electricity before conducting work.
4. BATTERY
When removing the battery cables, always be sure
to turn the ignition switch to OFF to prevent electri-
cal damage to the control module from overcurrent.
Be sure to remove the battery ground cable first.
5. IMMOBILIZER RELATED PART
Do not replace parts which have immobilizer ID (ig-
nition key, combination meter, body integrated unit
and ECM) with the parts from other vehicle.
6. SERVICE PARTS
Use genuine parts for maximum performance and
maintenance when conducting repairs. Subaru/FHI
will not be responsible for poor performance result-
ing from the use of parts except for genuine parts.
7. PROTECTING VEHICLE UNDER MAIN-
TENANCE
Make sure to attach the fender cover, seat covers,
etc. before work.
8. ENSURING SECURITY DURING WORK
When working in a group of two or more, perform
the work with calling each other to ensure mutual
safety.
9. LIFT AND JACK
When using a lift or shop jack to raise a vehicle or
using rigid rack to support a vehicle, always follow
instructions concerning jack-up points and weight
limits to prevent the vehicle from falling, which
could result in injury. Be especially careful that the
vehicle is balanced before raising it. Be sure to set
the wheel stoppers when jacking-up only the front
or rear side of the vehicle.
CAUTION:
Select the lift attachment so that the side sill
does not contact the lift arm.
NOTE:
• When using a lift, follow its operation manual.
• When the side sill cover contacts the lift arm, use
a lift attachment.
• Do not work or leave unattended while the vehi-
cle is supported with jack, support it with rigid
racks.
• Be sure to use the rigid racks with rubber at-
tached to cradle to support the vehicle.
• When using a lift, use an attachment or some-
thing similar.
• When using a plate lift, use a rubber attachment.
Place the attachment to the specified position of
the vehicle, by adjusting front/rear and left/right
sides accordingly.

NOTE
• When using an attachment, align the center of attachment (A) with the center of vehicle rib (the center of
spoiler rib).
• Do not use the plate lift whose attachment does not reach the supporting locations.
