Description]
Observe the following precautions to ensure safe and proper servicing. These precautions are not described in each individual section.
Precaution for supplemental restraint system (srs) "air bag" and "seat belt pre-tensioner"
The Supplemental Restraint System such as “AIR BAG” and “SEAT BELT PRE-TENSIONER”, used along with a front seat belt, helps to reduce the risk or severity of injury to the driver and front passenger for certain types of collision. Information necessary to service the system safely is included in the SR and SB section of this Service Manual.
WARNING:
PRECAUTIONS WHEN USING POWER TOOLS (AIR OR ELECTRIC) AND HAMMERS
WARNING:
Procedures without cowl top cover
When performing the procedure after removing cowl top cover, cover the lower end of windshield with urethane, etc.

Cautions in removing battery terminal and av control unit (models with av control unit)
CAUTION: Remove battery terminal and AV control unit after a lapse of 30 seconds or more after turning the ignition switch OFF.
NOTE: After the ignition switch is turned OFF, the AV control unit continues operating for approximately 30 seconds.
Therefore, data corruption may occur if battery voltage is cut off within 30 seconds.
General precautions
Keep the work area well ventilated and free of any inflammable materials. Special care should be taken when handling any inflammable or poisonous materials, such as gasoline, refrigerant gas, etc. When working in a pit or other enclosed area, be sure to properly ventilate the area before working with hazardous materials.
Do not smoke while working on the vehicle.

These operations should be done on a level surface.

Disconnect the negative battery terminal.

Do not remove the radiator cap when the engine is hot.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
Static electricity may damage internal electronic components.


Take caution that keys, buckles or buttons do not scratch paint.

WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness connectors which are related to the engine control system and TCM (transmission control module) system. The connectors should be disconnected only when working according to the WORK FLOW of TROUBLE DIAGNOSES in EC and TM sections.
Three way catalyst
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To prevent this, follow the instructions.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three way catalyst
Fuel (regular unleaded gasoline recommended)
Use unleaded regular gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) number (Research octane number 91). E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) may only be used in vehicles specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models).
CAUTION: Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Do not use E-85 fuel (85% fuel ethanol, 15% unleaded gasoline) unless the vehicle is specifically designed for E-85 fuel (i.e. Flexible Fuel Vehicle - FFV models). Using a fuel other than that specified could adversely affect the emission control devices and systems, and could also affect the warranty coverage validity.
Multiport fuel injection system or engine control system
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
