Vehicle Engine Control Unit Reset Procedure
After replacing the engine oil, it is recommended to have a repair shop \
such as an
Authorized Mazda Dealer perform the initialization (engine oil data res\
etting) of the
recorded value. If the value recorded by the computer is not initialized\
, the wrench indicator
light may not turn off or it may turn on earlier than normal.
Refer to Maintenance Monitor on page 6-18.

Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal
operating temperature.
3. Turn it off and wait at least 5 minutes
for the oil to return to the oil pan.
4. Pull out the dipstick, wipe it clean, and
reinsert it fully.

MAX
OK
MIN
5. Pull it out again and examine the level.
The level is normal if it is between the
MIN and MAX marks.
If it is near or below MIN, add enough
oil to bring the level to MAX.
CAUTION
Do not overfill the engine oil. This may
cause engine damage.
6. Make sure the O-ring on the dipstick is
positioned properly before reinserting
the dipstick.
7. Reinsert the dipstick fully.
Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live flame in the
engine compartment. DO NOT ADD
COOLANT WHEN THE ENGINE IS HOT:
A hot engine is dangerous. If the
engine has been running, parts of the
engine compartment can become very
hot. You could be burned. Carefully
inspect the engine coolant in the
coolant reservoir, but do not open it.
Pull over to a safe location, then
switch the ignition off and make sure
the fan is not running before attempting
to work near the cooling fan: Working near the cooling fan when it
is running is dangerous. The fan could
continue running indefinitely even if
the engine has stopped and the engine
compartment temperature is high. You
could be hit by the fan and seriously
injured.
Do not remove either cooling
system cap when the engine and
radiator are hot: When the engine and radiator are hot,
scalding coolant and steam may shoot
out under pressure and cause serious
injury.

NOTE
Changing the coolant should be done by
an Authorized Mazda Dealer.
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 F and L marks
on the coolant reservoir when the engine
is cool.
If it is at or near L, add enough coolant to
the coolant reservoir to provide freezing
and corrosion protection and to bring the
level to F.
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.

Owner Maintenance
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
L
Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold weather
to prevent it from freezing.
Body Lubrication
All moving points of the body, such as
door and hood hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.
Make sure the hood's secondary latch
keeps the hood from opening when the
primary latch is released.

Battery Maintenance
To get the best service from a battery:
 Keep it securely mounted. Keep the top clean and dry. Keep terminals and connections clean,
tight, and coated with petroleum jelly or
terminal grease.
 Rinse off spilled electrolyte immediately
with a solution of water and baking
soda.
 If the vehicle will not be used for an
extended time, disconnect the battery
cables and charge the battery every six
weeks.
Inspecting Electrolyte Level
A low level of electrolyte fluid will cause
the battery to discharge quickly.
Upper le vel
Lo wer le vel
Inspect the electrolyte level at least once
a week. If it is low, remove the caps and
add enough distilled water to bring the
level between the upper and lower level
(illustration).
Do not overfill.
Examine the specific gravity of the
electrolyte with a hydrometer, especially
during cold weather. If it is low, recharge
the battery.
Battery Recharging
NOTE
 Before performing maintenance or
recharging the battery, turn off all
accessories and stop the engine.
 To disconnect the battery, remove the
negative cable first. Install it last when
connecting the battery.
 Be sure to remove the caps before
recharging the battery.
 If the battery quickly discharges
because, for example, the lights were
left on too long with the engine off,
slow-charge it as required by battery
size and charger capacity.
 If the battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it as
required by battery size and charger
capacity.
Battery Replacement
Contact an Authorized Mazda Dealer for a
battery replacement purchase.

Key Battery Replacement
If the buttons on the transmitter are
inoperable and the operation indicator
light does not flash, the battery may be
dead.
Replace with a new battery before the
transmitter becomes unusable.
CAUTION
 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
(CR2025 or equivalent).
The following conditions indicate that the
battery power is low:
 The KEY indicator light (green) flashes
in the instrument cluster for about 30
seconds after the engine is turned off
(for vehicles with a type A instrument
cluster (page 4-32), messages are
displayed in the instrument cluster).
 The system does not operate and
the operation indicator light on the
transmitter does not flash when the
buttons are pressed.
 The system's operational range is
reduced.
Replacing the battery at an Authorized
Mazda Dealer is recommended to prevent
damage to the key. If replacing the battery
by yourself, follow the instruction.
Replacing the key battery

WARNING
Never touch the glass portion of a
halogen bulb with your bare hands
and always wear eye protection when
handling or working around the bulbs:When a halogen bulb breaks, it is
dangerous. These bulbs contain
pressurized gas. If one is broken, it will
explode and serious injuries could be
caused by the flying glass.
If the glass portion is touched with
bare hands, body oil could cause the
bulb to overheat and explode when lit.
Always keep halogen bulbs out of the
reach of children: Playing with a halogen bulb is
dangerous. Serious injuries could be
caused by dropping a halogen bulb or
breaking it some other way.
CAUTION
When removing the lens or lamp unit
using a flathead screwdriver, make
sure that the flathead screwdriver does
not contact the interior terminal. If
the flathead screwdriver contacts the
terminal, a short circuit may occur.
NOTE
 To replace the bulb, contact an
Authorized Mazda Dealer.
 If the halogen bulb is accidentally
touched, it should be cleaned with
rubbing alcohol before being used.
 Use the protective cover and carton for
the replacement bulb to dispose of the
old bulb promptly and out of the reach
of children.
