Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
IMA System
The Insight has an Auto-Stop system that shuts the engine off under certain conditions to improve fuel economy when the vehicle comes to a stop. In Auto-Stop mode, driver input, such as releasing the brake pedal, causes the engine to restart.
Before servicing the Insight, turn the ignition switch to LOCK (0), and remove the key so the engine cannot be started.
Before doing any service on the Insight's IMA system, make sure to turn the battery module switch OFF and wait at least 5 minutes before working on the vehicle (see SERVICE PRECAUTIONS ).
