Safety belt extension assembly
If the safety belt is too short when fully extended,
there is a 20 cm (8 inch) safety belt extension
assembly that can be added (part number 611C22).
This assembly can be obtained from your dealer at
no cost.
Use only extensions manufactured by the same
supplier as the safety belt. Manufacturer
identification is located at the end of the webbing on
the label. Also, use the safety belt extension only if
the safety belt is too short for you when fully
extended.
Do not use extensions to change the fit of
the shoulder belt across the torso.
Safety belt maintenance
Inspect the safety belt systems periodically to make
sure they work properly and are not damaged.
Inspect the safety belts to make sure there are no
nicks, tears or cuts. Replace if necessary. All safety
belt assemblies, including retractors, buckles, front

of your vehicle. Accident statistics suggest that
children are safer when properly restrained in the
rear seating positions than in the front seating
position.
Never let a passenger hold a child on his or
her lap while the vehicle is moving. The
passenger cannot protect the child from injury in a
collision.
Always follow the instructions and warnings that
come with any infant or child restraint you might
use.
Children and safety belts
If the child is the proper size, restrain the child in a
safety seat. Children who are too large for child
safety seats (as specified by your child safety seat
manufacturer) should always wear safety belts.
Follow all the important safety restraint and air bag
precautions that apply to adult passengers in your
vehicle.
If the shoulder belt portion of a combination lap and
shoulder belt can be positioned so it does not cross
or rest in front of the child’s face or neck, the child
should wear the lap and shoulder belt. Moving the
child closer to the center of the vehicle may help
provide a good shoulder belt fit.
Do not leave children, unreliable adults, or
pets unattended in your vehicle.
Child booster seats
Children outgrow a typical convertible or toddler
seat when they weigh 40 pounds and are around 4
years of age. Although the lap/shoulder belt will
provide some protection, these children are still too
small for lap/shoulder belts to fit properly, which
could increase the risk of serious injury.
To improve the fit of both the lap and shoulder belt
on children who have outgrown child safety seats,
