& WARNING (continued)
• Always adjust the driver's seat and the steering wheel so that
there are at least 4 inches 110 cm) between the knees and the
lower part of the instrument panel.
• Always hold the steering wheel on the outside of the steering
wheel rim with your hands at the 9 o'clock and 3 o'clock positions
to help reduce the risk of personal injury if the driver's airbag inflates .
• Never hold the steering wheel at the 12 o'clock position or with
your hands at other positions inside the steering wheel rim or on
the steering wheel hub. Holding the steering wheel the wrong way can cause serious injuries to the hands, arms and head if the
driver's airbag inflates
• Pointing the steering wheel toward your face decreases the
ability of the supplemental driver's airbag to protect you in a colli­
sion .
• Always sit in an upright position and never lean against or
place any part of your body too close to the area where the airbags
are located.
• Before driving, always adjust the front seats and head
restraints properly and make sure that all passengers are properly
restrained.
• Never adjust the seats while the vehicle is moving. Your seat
may move unexpectedly and you could lose control of the vehicle.
• Never drive with the backrest reclined or tilted far back! The
farther the backrests are tilted back, the greater the risk of injury
due to incorrect positioning of the safety belt and improper
seating position.
• Children must always ride in child seats

precautions apply when installing a child seat on the front
passenger seat

Proper seating position for the front
passenger
The proper front passenger seating position is important
for safe, relaxed driving.
For your own safety and to reduce the risk of injury in the
event of an accident, we recommend that you adjust the
seat for the front passenger to the following pos ition:
- Move the front passenger seat back as far as possible.
There must be a minimum of 10 inches (25 cm) between
the breastbone and the instrument panel =>
&.
- Adjust the angle of the seatback so that it is in an upright
position and your back comes in full contact with it
whenever the vehicle is moving.
- Adjust the head restraint so that the upper edge is as
even with the top of your head as possible but not lower
than eye level and so that it is as close to the back of your
head as possible =>
page 151.
-Keep both feet flat on the floor in front of the front
passenger seat.
- Fasten and wear safety belts correctly=>
page 163.
For detailed information on how to adjust the front passenger's

& WARNING
Improperly stored luggage or other items can fly through the
vehicle causing ser ious personal injury in the event of hard br aking
or an a ccident. To help reduce the risk of serious personal injury :
• Always put objects , for e xample , luggage or other heavy items
in the luggage compartment.
& WARNING
Heavy loads will influence the way your vehicle handles. To help
reduce the risk of a loss of control leading to serious personal
injury :
• Always keep in mind when transporting heavy objects , that a
change in the center of gravity can also cause changes in vehicle
handling:
-Always distribute the load as e venly as possible .
- Place heavy objects as far forward in the luggage compart -
ment as possible .
• Never exceed the Gross Axle Weight Rating or the Gros s
Vehicle Weight Rating specified on the safety compliance sti cker

-Safety belts ___ .:,__ _____________________________________ _
Automatic safety belt retractors
Every safety belt is equipped with an automatic belt retractor on the
shoulder bel t. This featu re locks the bel t when the belt is pulled out
fast, during hard braking and in an accident. The belt may also lock
when you drive up or down a steep hill or through a sharp curve. During normal driving the bel t lets you move freely.
Safety belt pretensioners
The safety belts are equipped with a belt pretension er that helps to
tighten the safety belt and remove slack when the pretensioner is
activated. The function of the pretensioner is monitored by a
warning light:::::, page
20, "Airbag system @;".
Switchable locking feature
Every safe ty belt except the one on the driver seat is equipped with
a switchable locking feature that must be used when the safety belt
is used to attach a child seat . Be sure to read the important informa­
tion about this feature:::::, page
200.
& WARNING
Improperly positioned safety belts can cause serious injury in an
accident :::::,
page 164, "Safety belt position" .
• Safety belts offer optimum protection only when the seat back
is upright and belts are properly positioned on the body.
• Never attach the safety belt to the buckle for another seat.
Attaching the belt to the wrong buckle will reduce safety belt
effectiveness and can cause serious personal injury.
• A passenger who is not properly restrained can be seriously
injured by the safety belt itself when it moves from the stronger
parts of the body into critical areas like the abdomen.
• Always lock the convertible locking retractor when you are
securing a child seat in the vehicle :::::,

Important safety instructions for using child
safety seats
Correct use of child safety seats substantially reduces the
risk of injury in an accident!
As the driver, you are responsible for the safety of every
­
body in the vehicle, especially children:
- Always use the right child safety seat for each child and
always use it properly~
page 195.
-Always carefully follow the child safety seat manufac­
turer's instructions on how to route the safety belt prop­
erly through the child safety seat.
- When using the vehicle safety belt to install a child safety
seat , you must first activate the convertible locking
retractor on the safety belt to prevent the child safety
seat from moving~
page 200.
-Push the child safety seat down with your full weight to
get the safety belt really tight so that the seat cannot
move forward or sideways more than one inch (2.5 cm).
- If a strap or tether is being used to tie the child safety
seat to the front passenger seat, make sure that it is not
so tight that it causes the weight-sensing mat to
measure more weight than is actually on the seat.
Always remember: Even though your vehicle is equipped with an
Advanced Airbag system, all children, especially those 12 years and
younger, should always ride in the back seat properly restrained for
their age and size. •
