What safety precautions must I follow when using the Innova 5610?

Always turn the ignition off before connecting or disconnecting the Scan Tool from the vehicle's DLC to prevent damage to the tool and vehicle's electronic components. Operate the vehicle only in a well-ventilated area to avoid carbon monoxide poisoning. Before starting the engine, engage the parking brake, put the transmission in park (automatic) or neutral (manual), and block the drive wheels. Never replace parts based only on DTC definitions; always consult the vehicle's service manual for proper testing procedures.
