Battery
▼Battery
WARNING
Wash hands after handling the battery
and related accessories:
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the
State of California to cause cancer and
reproductive harm.
Read the following precautions
carefully before using the battery or
inspecting to ensure safe and correct
handling:
Always wear eye protection
when working near the battery:
Working without eye protection is
dangerous. Battery fluid contains
SULFURIC ACID which could cause
blindness if splashed into your eyes.
Also, hydrogen gas produced during
normal battery operation, could ignite
and cause the battery to explode.
Wear eye protection and
protective gloves to prevent contact
with battery fluid:
Spilled battery fluid is dangerous.
Battery fluid contains SULFURIC ACID
which could cause serious injuries if it
gets in eyes, or on the skin or clothing.
If this happens, immediately flush your
eyes with water for 15 minutes or wash
your skin thoroughly and get medical
attention.
Always keep batteries out of
the reach of children:
Allowing children to play near batteries
is dangerous. Battery fluid could cause
serious injuries if it gets in the eyes or
on the skin.
Keep flames and sparks away
from open battery cells and do not
allow metal tools to contact the
positive (+) or negative (-) terminal of
the battery when working near a
battery. Do not allow the positive (+)
terminal to contact the vehicle body:
Flames and sparks near open battery
cells are dangerous. Hydrogen gas,
produced during normal battery
operation, could ignite and cause the
battery to explode. An exploding
battery can cause serious burns and
injuries. Keep all flames including
cigarettes and sparks away from open
battery cells.

Keep all flames and sparks
away from open battery cells because
hydrogen gas is produced from open
battery cells while charging the
battery or adding battery fluid:

NOTE
Before performing battery
maintenance, remove the battery
cover.
▼ Battery Maintenance
To get the best service from a battery:
Keep it securely mounted.Keep the top clean and dry.Keep terminals and connections

Make sure the battery is installed
correctly. Battery leakage could occur
if it is not installed correctly.
When replacing the battery, be
careful not to touch any of the
internal circuitry and electrical
terminals, bend the electrical
terminals, or get dirt in the
transmitter as the transmitter could
be damaged.
There is the danger of explosion if
the battery is not correctly replaced.
Dispose of used batteries according
to the following instructions.
Insulate the plus and minus
terminals of the battery using
cellophane or equivalent tape.
Never disassemble.
Never throw the battery into fire or
water.
Never deform or crush.
Replace only with the same type
battery (CR2032 or equivalent).
The following conditions indicate that
the battery power is low:
A message, “Low Key Fob Battery.
Replace Battery” is displayed on the
multi-information display when the

Tires
▼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 Di fferent Tire Types:
Driving your vehicle with di fferent
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
speci fied for the vehicle (page 9-10)
is dangerous. It could seriously a ffect
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 speci fied for the
vehicle.

▼Tire In
flation Pressure
WARNING
Always in flate the tires to the correct
pressure:
Overin flation or underin flation of tires
is dangerous. Adverse handling or
unexpected tire failure could result in a
serious accident.
Refer to Tires on page 9-10.
Use only a Mazda-genuine tire valve
cap:
Use of a non-genuine part is
dangerous as the correct tire air
pressure cannot be maintained if the
tire valve becomes damaged. If the
vehicle is driven under this condition,
the tire air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tire valve cap that is not a
Mazda-genuine part.
Inspect all tire pressures monthly
(including the spare) when the tires are
cold. Maintain recommended
pressures for the best ride, handling ,
and minimum tire wear.
Refer to the specification charts (page
9-10).
NOTE
Always check tire pressure when tires
are cold.
Warm tires normally exceed
recommended pressures. Do not
release air from warm tires to adjust
the pressure.
Underin flation can cause reduced
fuel economy, uneven and
accelerated tire wear, and poor
sealing of the tire bead, which will
deform the wheel and cause
separation of tire from rim.
Overin flation can produce a harsh
ride, uneven and accelerated tire
wear, and a greater possibility of
damage from road hazards.
Keep your tire pressure at the correct
levels. If one frequently needs in flating, have it inspected.
▼ Tire Rotation
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.
1. Forward
Do not include (TEMPORARY USE
ONLY) spare tire in rotation.
