Safe Driving
For Safe Driving
The following pages explain your vehicle's safety features and how to use them
properly. The safety precautions below are ones that we consider to be among the
most important.
Important Safety Precautions
■Always wear your seat belt
A seat belt is your best protection in all types of collisions. Airbags are designed to
supplement seat belts, not replace them. So even though your vehicle is equipped
with airbags, make sure you and your passengers always wear your seat belts, and
wear them properly.
■Restrain all children
Children ages 12 and under should ride prop erly restrained in a back seat, not the
front seat. Infants and small children should be restrained in a child seat. Larger
children should use a booster seat and a lap/shoulder seat belt until they can use the
belt properly without a booster seat.
■Be aware of airbag hazards
While airbags can save lives, they can cause serious or fatal injuries to occupants
who sit too close to them, or are not prop erly restrained. Infants, young children,
and short adults are at the greatest risk. Be sure to follow all instructions and
warnings in this manual.
■Don't drink and drive
Alcohol and driving don't mix. Even one dr ink can reduce your ability to respond to
changing conditions, and your reaction time gets worse with every additional drink.
So don't drink and drive, and don't let your friends drink and drive, either.
1Important Safety Precautions
Some states, provinces and te rritories prohibit the use
of cell phones other than hands-free devices by the
driver while driving.

Your Vehicle’s Safety Features
The following checklist will help you take an active role in protecting yourself and
your passengers.
1 Your Vehicle’s Safety Features
Your vehicle is equipped wi th many features that
work together to help protect you and your
passengers during a crash.
Some features do not require any action on your part.
These include a strong steel framework that forms a
safety cage around the passenger compartment,
front and rear crush zones, a collapsi ble steering
column, and tensioners that tighten the front seat
belts in a sufficient crash.
However, you and your passe ngers cannot take full
advantage of these features unless you remain seated
in the correct position and always wear your seat
belts. In fact, some safety features can contribute to
injuries if they are not used properly.
