Inspect the electrolyte level at least once a
week. If it's low, remove the caps and add
enough distilled water to bring the level
between the upper and lower level
(illustration).
Don't overfill.
Examine the specific gravity of the
electrolyte with a hydrometer, especially
during cold weather. If it's low, recharge
the battery.Tires
For reasons of proper performance, safety,
and better fuel economy, always maintain
recommended tire inflation pressures and
stay within the recommended load limits
and weight distribution.
WARNING
Using Different Tire Types:Driving your vehicle with different
types of tires is dangerous. It could
cause poor handling and poor
braking; leading to loss of control.
Except for the limited use of the
temporary spare tire, use only the
same type tires (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tires: Using any other tire size than what is
specified for your Mazda (page 10-11)
is dangerous. It could seriously affect
ride, handling, ground clearance, tire
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tires that
are the correct size specified for your
Mazda.

WARNING
Dry wet brakes by driving very slowly
and applying the brakes lightly until
brake performance is normal:Driving with wet brakes is
dangerous. Increased stopping
distance or the vehicle pulling to one
side when braking could result in a
serious accident. Light braking will
indicate whether the brakes have
been affected.
qAluminum Wheel Maintenanceí
A protective coating is provided over the
aluminum wheels. Special care is needed
to protect this coating.
CAUTION
Do not use any detergent other than
mild detergent. Before using any
detergent, verify the ingredients.
Otherwise, the product could discolor
or stain the aluminum wheels. NOTE
lDo not use a wire brush or any abrasive
cleaner, polishing compound, or solvent on
aluminum wheels. They may damage the
coating.
lAlways use a sponge or soft cloth to clean
the wheels.
Rinse the wheels thoroughly with lukewarm
or cold water. Also, be sure to clean the
wheels after driving on dusty or salted
roads to help prevent corrosion.
lAvoid washing your vehicle in an automatic
car wash that uses high-speed or hard
brushes.
lIf your aluminum wheels lose luster, wax
the wheels.
(With Tire Pressure Monitoring System)
Check special requirements for Tire Pressure
Monitoring System.
Refer to Tires and Wheels on page 5-35.
q Plastic Part Maintenance
lWhen cleaning the plastic lenses of the
lights, do not use gasoline, kerosene,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolor or damage the
surfaces resulting in a significant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, flush with water
immediately.
lIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
gasoline, oil, engine coolant, or battery
fluid, it could cause discoloration,
staining, or paint peeling. Wipe off any
such chemical agents or fluids using a
soft cloth immediately.
