Black plate (26,1)
Seat Warmerí
The driver and front passenger seats can
be warmed by rotating the applicable seat
warmer dial while the ignition is switched
ON.
The seat temperature increases as the
number on the dial increases. When the
seat warmers are not in use, rotate the seat
warmer dials to 0.
WARNING
ØBe careful when using the seat
warmer. The heat from the seat
warmer may be too hot for some
people, as indicated below, and
could cause a low-temperature
burn.
ØInfants, small babies, elderly
people, and physically
challenged people
ØPeople with delicate skin
ØPeople who are excessively
fatigued
ØPeople who are intoxicated
ØPeople who have taken sleep-
inducing medicine such as
sleeping pills or cold medicine
Ø Do not use the seat warmer with
anything having high moisture-
retention ability such as a blanket
or cushion on the seat. The seat
may be heated excessively and
cause a low-temperature burn.
Ø Do not use the seat warmer even
when taking a short nap in the
vehicle. The seat may be heated
excessively and cause a low-
temperature burn.
Ø Do not place heavy objects with
sharp projections on the seat, or
insert needles or pins into it. This
could cause the seat to become
excessively heated and result in
injury from a minor burn.

Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being discharged,
do not leave the fan control dial on for a long
period of time with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filterí
Your vehicle is equipped with an air filter
for the air conditioner. It is necessary to
change the filter periodically as indicated
in scheduled maintenance (page 8-3).
Consult an Authorized Mazda Dealer for
replacement of the cabin air filter.

qOperating Tips for CD Player/In-
Dash CD Changer
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in the
CD player/In-dash CD changer may
become clouded with condensation. At
this time, the CD will eject immediately
when placed in the unit. A clouded CD
can be corrected simply by wiping it with
a soft cloth. Clouded optical components
will clear naturally in about an hour. Wait
for normal operation to return before
attempting to use the unit.
Handling the CD player/In-dash CD
changer
The following precautions should be
observed.
lDo not spill any liquid on the audio
system.
lDo not insert any objects, other than
CDs, into the slot.
lThe CD revolves at high speed within
the unit. Defective (cracked or badly
bent) CDs should never be used.
lDo not use non-conventional discs
such as heart-shaped, octagonal discs,
etc. The disc may not eject resulting in
a malfunction.
lIf the memory portion of the CD is
transparent or translucent, do not use
the disc.

Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a year―at the beginning of the
winter season ―and before traveling
where temperatures may drop below
freezing.
Inspect the condition and connections of
all cooling system and heater hoses.
Replace any that are swollen or
deteriorated.
The coolant should be at full in the
radiator and between the MAX and MIN
marks on the coolant reservoir when the
engine is cool.
If it is at or near MIN, add enough coolant
to the coolant reservoir to provide
freezing and corrosion protection and to
bring the level to MAX.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
Ø Radiator coolant will damage
paint.
Rinse it off quickly if spilled.
Ø Use only soft (demineralized)
water in the coolant mixture.
Water that contains minerals will
cut down on the coolant's
effectiveness.
Ø Do not add only water. Always
add a proper coolant mixture.
Ø The engine has aluminum parts
and must be protected by an
ethylene-glycol-based coolant to
prevent corrosion and freezing.
Ø DO NOT USE coolants Containing
Alcohol, methanol, Borate or
Silicate.
These coolants could damage the
cooling system.
Ø DO NOT MIX alcohol or methanol
with the coolant. This could
damage the cooling system.
Ø Do not use a solution that
contains more than 60%
antifreeze.
This would reduce effectiveness.
