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  territories prohibit the use 
of cell phones other than  hands-free devices by the 
driver while driving.

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 re gularly scheduled maintenance.

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.

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. 124
•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 Adjusting the Seats  P. 156
•Adjust head restraints to  the proper position. Head restraints are most effective 
when the center of the head restraint alig ns with the center of your head. Taller 
persons should adjust their head  restraint to the highest position.
2Adjusting the Head Restraints P. 159
•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. 33
•Protect children by using seat belts or chil d seats according to a child’s age, height 
and weight.
2 Child Safety  P. 52
