64Safe Driving
Exhaust Gas HazardCarbon Monoxide GasThe 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 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 climate control system in the same manner if you sit in your parked
vehicle with the engine running.
1Carbon Monoxide Gas
An enclosed area such as a garage can quickly fill up
with carbon monoxide gas.
Do not run the engine with the garage door closed.
Even when the garage door is open, drive out of the
garage immediately after starting the engine.

WARNING
Carbon monoxide gas is toxic.
Breathing it can cause unconsciousness and
even kill you.
Avoid any enclosed areas or activities that
expose you to carbon monoxide.
