For Safe DrivingThe 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 properly 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 properly 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 drink can reduce your ability to respond to 
changing conditions, and  your reaction time gets worse with every additional drink. 
So don’t drink and dri ve, 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.

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 regularly scheduled maintenance.

Safe Driving
Important Handling InformationYour vehicle has higher ground clearance than a passenger vehicle designed for use 
only on pavement. High er ground clearance has many advantages for off-highway 
driving. It allows you to travel over bumps, obstacles, and rough terrain. It also 
provides good visibility so you can anticipate problems earlier.
These advantages come at some cost. Because your vehicle is taller and rides higher 
off the ground, it has a higher center gravity making it more susceptible to tripping 
or roll over if you make abrupt turns. Utility vehicles have a significantly higher 
rollover rate than other types of vehicles. In a rollover crash, an unbelted person is 
significantly more likely to die than a person wearing a seat belt. As a reminder, 
make sure you and your passengers always wear seat belts.

Your Vehicle’s Safety FeaturesThe following checklist will help you take an active role in protecting yourself and 
your passengers.
1Your Vehicle’s Safety Features
Your vehicle is equipped with 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 collapsible steering 
column, and tensioners that tighten the front seat 
belts in a sufficient crash.
However, you and your passengers 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.
