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

of position at the time of air bag deployment. It is
extremely important that occupants be properly
restrained as far away from the air bag module as
possible while maintaining vehicle control.
The SRS consists of:
•driver and passenger air bag modules (which
include the inflators and air bags)
•one or more impact and safing sensors
•a readiness light and tone
•a diagnostic module
•and the electrical wiring which connects the
components
The diagnostic module monitors its own internal
circuits and the supplemental air bag electrical
system wiring (including the impact sensors), the
system wiring, the air bag system readiness light, the
air bag back up power and the air bag ignitors.
Several air bag system components get hot
after inflation. Do not touch them after
inflation.
If the air bag has deployed,the air bag will
not function again and must be replaced
immediately.If the air bag is not replaced, the
unrepaired area will increase the risk of injury in a
collision.
Determining if the system is operational
The SRS uses a readiness light in the instrument
cluster or a tone to indicate the condition of the
system. Refer toAir bag readinesssection in the
Instrument clusterchapter. Routine maintenance of
the air bag is not required.
