-
Before work, set the wheel stoppers to secure the vehicle.
-
When performing work by multiple workers, call to each other to make sure that service operation is performed safely.
-
Ventilate the room when starting the engine.
-
When performing the service operation of high-temperature parts like muffler, or rotating parts like fan and other movable parts, be careful not to get burned or injured.
-
For the jack-up and lift up, set the tool to the proper location to support the vehicle correctly. And use the safety device properly when lifting up.
-
By identifying the vehicle problems thoroughly before work, service operation will be performed effectively.
-
Before removing parts, confirm the installation condition or the damage of the parts.
-
To reinstall parts properly, leave a note of the condition before work as necessary.
-
For a part which needs positioning, take appropriate action such as putting alignment marks.
-
For a removed part, clean it as necessary and check for damage and defect before installation. If a part is damaged or does not work properly, replace it with a new part.
-
Removing or installing the components or the connectors with the ignition switch ON will electrically impair them.
-
Reconnect the harness connectors for each control module one or more minutes after disconnecting them.
-
For installation of the bolt, nut, and screws, use tools suitable for each dimension, and use them vertically and securely.
-
A removed part must be organized to avoid mixing up with similar parts. When same parts are used in multiple locations, such as pistons in engine, manage the parts by using labels with cylinder No. so that the parts are not installed to the wrong location.
-
Always replace non-reusable parts such as gasket and O-ring with new parts.
-
After work, have a customer confirm the replaced part.
-
Use genuine parts for maximum performance and maintenance when conducting repairs. SUBARU CORPORATION will not be responsible for poor performance resulting from the use of parts except for genuine parts.

Do not spray parts cleaner directly to rubber parts such as bushing or other resin parts.
-
Perform the operation in a clean location and use extra caution in dust proofing.
-
Clean the items (except for assembly components) 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.
-
Use an appropriate cleaning solvent.
-
Do not clean rubber parts such as O-ring, gasket and oil seal with cleaning solution.
Fasteners must be tightened to the specified torque.
To prevent bolt and nut looseness, do not apply paint, lubricant, rust retardant or other substance to the installation surfaces of bolts, nuts, etc.
Use an appropriate sized tool. Insert a screw vertically into the hole. Check for any loose screws after installation.
If improper tools are used or screws are inserted obliquely to the hole, the screws cannot be installed correctly, which may result in insufficient tightening force or damage on the hole.
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 prevention cord or touch grounded metal for the elimination of static electricity before conducting work.
Always refer to “CAUTION” of “General Description” in the same models service manual before starting the diagnostics and repair.
Always refer to the cautions of each section when diagnosing and repairing each system and component.
The battery cable must be disconnected from the battery sensor ground terminal after the ignition switch is set to the OFF position, unless otherwise required by the diagnostics.
When disconnecting a connector, do not pull the harness, but pull while holding the connector housing.
Confirm the locking shape completely before disconnecting a connector. In addition, firmly push in the connector until a click sounds when connecting a connector.
Be sure to prevent water or oil from contacting the connector terminals except for the integrated connector.
When checking continuity between connector terminals, or measuring voltage across the terminal and ground, always touch tester probe(s) to terminals from the harness side.
When measuring the waterproof type connector terminal voltage, or the resistance between the terminals, use the check board.
If the probe is too thick to gain access to the terminal, do not push it in forcibly but use a mini test lead.
When measuring the voltage or resistance of individual sensors or all electrical control modules, use a tapered pin with a diameter of 0.6 mm (0.024in) or less and touch it to the tip of terminal. Never insert the tapered pin into the terminal at this time. Doing so may cause internal deformation and a malfunction can occur.
If a taper pin or the like has been inserted into the connector terminal, replace the connector.
To check waterproof type connectors (which are not measurable from the harness side), touch tester probes on the terminal side and be very careful not to bend or damage the terminals.
Securely fasten the harness with clamps and clips so that the harness does not interfere with the body end parts, edges, bolts or screws.
When installing a harness and a component, be careful not to catch them on the harness.
Sensors, relays, units, etc., are sensitive to strong impacts. Handle them with extra care so that they are not dropped or mishandled.
When inspecting the airbag system, in order to
avoid malfunction, always refer to “CAUTION” of “General Description” of
the airbag system in the same model’s service manual. AIRBAG SYSTEM>General Description>CAUTION
