Seat Belt Maintenance
WARNING
If a seat belt appears frayed or has
abrasions, have it replaced by an
Authorized Mazda Dealer.
If a seat belt is used under such a
condition, it cannot function at its full
capacity which could result in serious
injury or death.
Use a mild detergent to remove
soiling from a seat belt.
If organic solvents are used for cleaning
the seat belts or they become stained
or bleached, there is the possibility of
them becoming weakened and as a
result, they may not function at their
full capacity which could cause serious
injury or death.
Do not disassemble, modify, or
replace a seat belt.
If a seat belt is used under such a
condition, it cannot function at its full
capacity which could result in serious
injury or death.
Always have your vehicle inspected by
an Authorized Mazda Dealer if the
vehicle has been involved in an
accident.
Seat belts with the pretensioner system
and the seat belts with the load-limiter
system cannot be reused once they
have operated (deployed).
If a seat belt is used under such a
condition, it cannot function at its full
capacity which could result in serious
injury or death.
Always consult an Authorized Mazda
Dealer when scrapping the vehicle.
If the pretensioner system operates
(deploys) unexpectedly, it could result
in serious injury or death.
Do not repair the pretensioner system
parts or wiring harnesses and do not
attempt diagnose the pretensioner
system circuits using an electrical
tester or similar device.
Otherwise, they may not function
normally or they may operate
incorrectly, which could result in
serious injury or death.

Check periodically that the seat belt
systems work properly and are not
damaged.

1. Lightly tap with a mild detergent toremove dirt.
2. Wipe with a thoroughly wrung cloth.
3. Allow to dry.
4. Make sure that the seat belt locks
when it is pulled rapidly. If it is still
not retracting properly, have it
inspected at an Authorized Mazda
Dealer.
NOTE
Clean seat belts diligently if they get
dirty. Leaving them uncleaned will
make it difficult to clean them later,
and it may affect the smooth retracting
of the seat belt.
