2 –5 Essential Safety Equipment
Seats
* Some models. Seat Warmer *
The seats are electrically heated. The
ignition must be switched ON.
Press the seat warmer switch while the
ignition is switched ON to operate the seat
warmer. The indicator lights turn on to
indicate that the seat warmer is operating.
The mode changes as follows each time
the seat warmer switch is pressed.

WARNING Be careful when using the seat warmer:
The heat from the seat warmer may be
too hot for some people, as indicated
as follows, and could cause a low-
temperature burn. 
Infants, small children, elderly
people, and physically challenged
people 
People with delicate skin 
People who are excessively fatigued 
People who are intoxicated 
People who have taken sleep-
inducing medicine such as sleeping
pills or cold medicine 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.
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.
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.
CAUTION Do not use organic solvents to clean
the seat. It may damage the seat
surface and the heater.
NOTE 
If the ignition is switched off while the
seat warmer is operating (High, Mid or
Low) and then switched ON again, the
seat warmer will automatically operate
at the temperature set before switching
off the ignition. 
Use the seat warmer when the engine
is running. Leaving the seat warmer
on for long periods with the engine not
running could cause the battery power
to be depleted. 
The temperature of the seat warmer
cannot be adjusted beyond High, Mid
and Low because the seat warmer is
controlled by a thermostat.

5 –16 Interior Features
Audio System Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas
is characterized by sound breakup.
Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are extremely
strong, so the result is noise and sound
breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance. Station 2
88.3 MHzStation 1
88.1 MHz Operating Tips for CD Player 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 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
The following precautions should be
observed. 
Do not use deformed or cracked CDs.
The disc may not eject resulting in a
malfunction. 
Do not use non-conventional discs such
as heart-shaped, octagonal discs, etc.
The disc may not eject resulting in a
malfunction.

6 –30 Maintenance and Care
Owner Maintenance 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 FULL and LOW
marks on the coolant reservoir when the
engine is cool. Coolant reservoir
Cooling fa nCooling system cap
If it is at or near LOW, add enough coolant
to the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant. CAUTION 
Radiator coolant will damage paint.
Rinse it off quickly if spilled. 
Use only soft (demineralized) water in
the coolant mixture. Water that contains
minerals will cut down on the coolant's
effectiveness. 
Do not add only water. Always add a
proper coolant mixture. 
The engine has aluminum parts and
must be protected by an ethylene-glycol-
based coolant to prevent corrosion and
freezing. 
DO NOT USE coolants Containing
Alcohol, methanol, Borate or Silicate.
These coolants could damage the
cooling system. 
DO NOT MIX alcohol or methanol with
the coolant. This could damage the
cooling system. 
Do not use a solution that contains more
than 60% antifreeze.
This would reduce effectiveness. 
If the “FL22” mark is shown on or near
the cooling system cap, use of FL-22 is
recommended when replacing engine
coolant. Using engine coolant other
than FL-22 may cause serious damage to
the engine and cooling system.
If the coolant reservoir is empty or new
coolant is required frequently, consult an
Authorized Mazda Dealer.
