You will find many safety precautions
and recommendations throughout
this section, and throughout this
manual. The safety precautions in
this section are among the most
important.
Always Wear Your Seat Belt
A seat belt is your best protection in
all types of accidents. Air bags are
designed to supplement seat belts,
not replace them. So even though
your vehicle is equipped with air
bags, ALWAYS make sure you and
your passengers wear your seat
belts, and wear them properly.
Restrain All Children
All children under age 13 should ride
in your vehicle properly restrained in
a rear seat, not the front seat. Infants
and small children should be
restrained in an appropriate child
restraint. Larger children should use
a booster seat with the lap/shoulder
belt until they can use the seat belt
properly without a booster seat.
Air Bag Hazards
While air bags can save lives, they
can also cause serious or fatal
injuries to occupants who sit too
close to them, or who are not prop-
erly restrained. Infants, young chil-
dren, and shorter adults are at the
greatest risk of being injured by an
inflating air bag. Follow all instruc-
tions and warnings in this manual.
Driver Distraction
Driver distraction presents a serious
and potentially deadly danger, espe-
cially for inexperienced drivers.
Safety should be the first concern
when behind the wheel and drivers
need to be aware of the wide array of
potential distractions, such as
drowsiness, reaching for objects,
eating, personal grooming, other
passengers, and using cellular
phones.
Drivers can become distracted when
they take their eyes and attention off
the road or their hands off the wheel
to focus on activities other than driv-
ing. To reduce your risk of distraction
or getting into an accident:
• ALWAYS set up your mobile
devices (i.e., MP3 players, phones,
navigation units, etc.) when your
vehicle is parked or safely stopped.

Safety system of your vehicle
ONLY use your mobile device
when allowed by laws and when
conditions permit safe use. NEVER
text or email while driving. Most
states have laws prohibiting drivers
from texting. Some states and
cities also prohibit drivers from
using handheld phones.
NEVER let the use of a mobile
device distract you from driving.
You have a responsibility to your
passengers and others on the road
to always drive safely, with your
hands on the wheel as well as your
eyes and attention on the road.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 condi-
tions, regardless of the maximum
speed posted.
Keep Your Vehicle in Safe
Condition
Having a tire blowout or a mechani-
cal failure can be extremely haz-
ardous. To reduce the possibility of
such problems, check your tire pres-
sures and condition frequently, and
perform all regularly scheduled
maintenance.

Safety Precautions
Adjusting the seats so that you are
sitting in a safe, comfortable position
plays an important role in driver and
passenger safety together with the
seat belts and air bags in an acci-
dent.
Air bags
You can take steps to reduce the risk
of being injured by an inflating air
bag. Sitting too close to an air bag
greatly increases the risk of injury in
the event the air bag inflates.
The National Highway Traffic Safety
Administration (NHTSA) recom-
mends that drivers allow at least 10
inches (25 cm) between the center of
the steering wheel and their chest.
Seat belts
Always fasten your seat belt before
starting any trip.
At all times, passengers should sit
upright and be properly restrained.
Infants and small children must be
restrained in appropriate child
restraint systems. Adults and chil-
dren who have outgrown a booster
seat must be restrained using the
seat belts. Do not use a cushion that
reduces friction between the
seat and the passenger. The
passenger's hips may slide
under the lap portion of the seat
belt during an accident or a
sudden stop. Serious or fatal
internal injuries could result
because the seat belt cannot
operate properly.
WARNING
To reduce the risk of serious
injury or death from an inflating
air bag, take the following pre-
cautions:
•Adjust the driver's seat as far
to the rear as possible while
maintaining the ability to
maintain full control of the
vehicle.
Adjust the front passenger
seat as far to the rear as pos-
sible.
Hold the steering wheel by the
rim with hands at the 9 o'clock
and 3 o'clock positions to
minimize the risk of injuries to
your hands and arms.
NEVER place anything or any-
one between the steering
wheel and the air bag.
Do not allow the front passen-
ger to place feet or legs on the
dashboard to minimize the
risk of leg injuries.
