Safety Checklist
For the safety of you and your passengers, make a habit of checking these items
each time before you drive.
• After everyone has entered the vehicle, be sure all doors are closed and locked.
Locking the doors helps prevent an occupant from being ejected and an outsider
from unexpectedly opening a door.
2 Locking/Unlocking the Doors from the Inside P. 177
•Adjust your seat to a position suitable for driving. Be sure the front seats are
adjusted as far to the rear as possible while allowing the driver to control the
vehicle. Sitting too close to a front airbag can result in serious or fatal injury in a
crash.
2 Seats P. 212
•Adjust head restraints to the proper position. Head restraints are most effective
when the center of the head restraint aligns with the center of your head. Taller
persons should adjust their head restraint to the highest position.
2 Adjusting the Front and Rear Outer* Head Restraint Positions P. 219
•Always wear your seat belt, and make sure you wear it properly. Confirm that any
passengers are properly belted as well.
2 Fastening a Seat Belt P. 42
•Protect children by using seat belts or child seats according to a child’s age, height
and weight.
2 Child Safety P. 64
1Safety Checklist
If the door and/or trunk open message appears on
the driver information inte rface, a door and/or the

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 m aking 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.
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 immediat ely after 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.
