PRECAUTION

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.

1. Note

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.

(A) 80 mm (3.1 in) or more
(B) 80 — 100 mm (3.15 — 3.94 in)

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.
