uuFor Safe Driving uImportant Safety Precautions
Safe Driving
■Pay appropriate attention to the task of driving safely
Engaging in cell phone conversation or other activities that keep you from paying
close attention to the road, other vehicles, and pedestrians could lead to a crash.
Remember, situations can change quickly, and only you can decide when it is safe to
divert some attention away from driving.
■Control your speed
Excessive speed is a major factor in crash injuries and deaths. Generally, the higher
the speed, the greater the risk, but serious injuries can also occur at lower speeds.
Never drive faster than is safe for current conditions, regardless of the maximum
speed posted.
■Keep your vehicle in safe condition
Having a tire blowout or a mechanical failure can be extremely hazardous.
To reduce the possibility of such problems, check your tire pressures and condition
frequently, and perform all regul arly scheduled maintenance.
■Do not leave children unattended in the vehicle
Children, pets and people needing assistan ce left unattended in the vehicle may be
injured if they activate one or more of the vehicle controls. They may also cause the
vehicle to move, resulting in a crash in wh ich they and/or another person(s) can be
injured or killed. Also, depending on the am bient temperature, the temperature of
the interior may reach extreme levels, which can result in harm or death.
Even if the climate control system is on, never leave them in the vehicle unattended
as the climate control system can shut off at any time.

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 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.
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.
