WARNING
Do not perform maintenance work if you lack suffi cient knowledge and experience
or the proper tools and equipment to do the work. Have maintenance work done by a
qualifi ed technician:
Performing maintenance work on a vehicle is dangerous if not done properly. You can
be seriously injured while performing some maintenance procedures.
If you must run the engine while working under the bonnet, make certain that you
remove all jewellery (especially rings, bracelets, watches, and necklaces) and all
neckties, scarves, and similar loose clothing before getting near the engine or cooling
fan which may turn on unexpectedly:
Working under the bonnet with the engine running is dangerous. It becomes even more
dangerous when you wear jewellery or loose clothing.
Either can become entangled in moving parts and result in injury.
Switch the ignition to 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 indefi nitely 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 leave items in the engine compartment:
After you have fi nished checking or doing servicing in the engine compartment, do not
forget and leave items such as tools or rags in the engine compartment.
Tools or other items left in the engine compartment could cause engine damage or a fi re
leading to an unexpected accident.

Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live fl ame 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.
Switch the ignition to 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 indefi nitely 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 expert repairer, we recommend an
Authorised Mazda Repairer.
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 travelling
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.

SKYACTIV-D 2.2
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 (demineralised) 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 aluminium 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.
CAUTION
  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 expert repairer, we recommend an
Authorised Mazda Repairer.

If Trouble Arises
Battery Runs Out
Jump-Starting
Jump-starting is dangerous if done incorrectly. So follow the procedure carefully. If you
feel unsure about jump-starting, we strongly recommend that you have a competent service
technician do the work.
WARNING
Follow These Precautions Carefully:
To ensure safe and correct handling of the battery, read the following precautions
carefully before using the battery or inspecting it.
Do not allow the positive ( ) terminal to contact any other metal object that
could cause sparks:
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. When working near a battery,
do not allow metal tools to contact the positive (
) or negative () terminal of the
battery.
Keep all fl ames, including cigarettes, and sparks away from open battery cells:
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.
Do not jump-start a frozen battery or one with a low fl uid level:
Jump-starting a frozen battery or one with a low fl uid level is dangerous. It may rupture
or explode, causing serious injury.
Connect the negative lead to a good ground point away from the battery:
Connecting the end of the second jumper lead to the negative (
) terminal of the
discharged battery is dangerous.
A spark could cause the gas around the battery to explode and injure someone.
Route the jumper leads away from parts that will be moving:
Connecting a jumper lead near or to moving parts (cooling fans, belts) is dangerous.
The lead could get caught when the engine starts and cause serious injury.
