CAUTION

1. Never connect the battery in reverse polarity.

Doing so may immediately damage the auto A/C control module.

2. Do not disconnect the battery terminals while the engine is running.

A large counter electromotive force will be generated in the generator, and this voltage may damage electronic parts such as auto A/C control module etc.

3. Before disconnecting the connectors of sensors and the auto A/C control module, be sure to turn off the ignition switch.

Auto A/C control module may be damaged.

4. Every A/C-related part is a precision part. Do not drop them.

5. Airbag system wiring harness is routed near the A/C control panel (auto A/C control module) and junction box.
