Always keep lead-acid
batteries out of the reach of children.
Allowing children to play near
lead-acid batteries is dangerous.
Lead-acid battery fluid could cause
serious injuries if it gets in the eyes or
on the skin.
Keep flames and sparks
away from lead-acid battery cells and
do not allow metal tools to contact
the positive (+) or negative (-)
terminal of the lead-acid battery
when working near a lead-acid
battery. Do not allow the positive (+)
terminal to contact the vehicle body.
Flames and sparks near lead-acid
battery cells are dangerous. Hydrogen
gas, produced during normal lead-acid
battery operation, could ignite and
cause the lead-acid battery to explode.
An exploding lead-acid battery can
cause serious burns and injuries. Keep
all flames including cigarettes and
sparks away from lead-acid battery
cells.
Keep all flames and
sparks away from lead-acid battery
cells because hydrogen gas is
produced from lead-acid battery cells
while charging the lead-acid battery
or adding lead-acid battery fluid.
Flames and sparks near lead-acid

Keep your tire pressure at the correct
levels. If one frequently needsinflating, have it inspected.Rotating the Tires
WARNING
Rotate tires periodically.
Irregular tire wear is dangerous. To
equalize tread wear for maintaining
good performance in handling and
braking , rotate the tires periodically or
sooner if irregular wear develops.
Please refer to Scheduled maintenance
for your tire rotation interval.
During rotation, inspect them for
correct balance.


Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
Also, inspect them for uneven wear
and damage. Abnormal wear is usually
caused by one or a combination of the
following:

Incorrect tire pressureImproper wheel alignmentOut-of-balance wheelSevere braking

After rotation, inflate all tire pressures
to specification (page 10-71) and
inspect the lug nuts for tightness.

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.

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.
