IMA System
The CR-Z 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 CR-Z, turn the ignition switch to LOCK (0), and remove the key so the engine cannot be started.
Before doing any service on the CR-Z'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 ).
