Honda Civic Owners Manual: Exhaust Gas Hazard

Carbon Monoxide Gas

The engine exhaust from this vehicle contains carbon monoxide, a colorless, odorless, and highly toxic gas. As long as you properly maintain your vehicle, carbon monoxide gas will not get into the interior.

Have the exhaust system inspected for leaks whenever

• The exhaust system is making an unusual noise.
• The exhaust system may have been damaged.
• The vehicle is raised for an oil change.

When you operate a vehicle with the trunk open, airflow can pull exhaust gas into the interior and create a hazardous condition. If you must drive with the trunk open, open all the windows and set the heating system*/climate control system* as shown below.

1. Select the fresh air mode.

2. Select the mode.

3. Set the fan speed to high.

4. Set the temperature control to a comfortable setting.

Adjust the heating system*/climate control system* in the same manner if you sit in your parked vehicle with the engine running.

Carbon monoxide gas is toxic.

Avoid any enclosed areas or activities that expose you to carbon monoxide.

Even when the garage door is open, drive out of the garage immediately after starting the engine.
