Safe Driving
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 in spected for leaks whenever
• The exhaust system is ma king 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 hatch open, airflow can pull exhaust gas into
the interior and create a hazardous conditi on. If you must drive with the hatch 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.
1 Carbon 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 afte r starting the engine.
3WARNING
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.

Fuel Economy and CO2 Emissions
Improving Fuel Economy and Reducing CO2
Emissions
Achieving fuel economy and reducing CO2 emissions is dependent on several
factors, including driving conditions, load weight, idling time, driving habits, and
vehicle condition. Depending on these and other factors, you may not achieve the
rated fuel economy of this vehicle.
You can optimize your fuel economy with proper maintenance of your vehicle.
Always maintain your vehicle in accordance with the messages displayed on the
driver information interface.
• Use the recommended viscosity engine oil.
2 Recommended Engine Oil P. 582
•Maintain the specified tire pressure.
• Do not load the vehicl e with excess cargo.
• Keep your vehicle clean. A buildup of snow or mud on your vehicle's underside
adds weight and increases wind resistance.
■Maintenance and Fuel Economy
1Improving Fuel Economy and Reducing CO2 Emissions
Direct calculation is the recommended method to
determine actual fuel consumed while driving.
In Canada, posted fuel economy numbers are
established following a simulated test.
For more information on how this test is performed,
please visit https://www.nrcan.gc.ca and search for
“fuel consumption testing” in the search field at the
