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.

Maintenance and Care
Appearance Care
Plastic Part Maintenance
 












 When cleaning the plastic lenses of
the lights, do not use petrol, paraffi n,
rectifi ed spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these chemical
agents can discolour or damage the
surfaces resulting in a signifi cant loss
in functionality. If plastic parts become
inadvertently exposed to any of these
chemical agents, fl ush with water
immediately.
 


 If plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fl uids such as petrol,
oil, engine coolant, or battery fl uid, it
could cause discolouration, staining,
or paint peeling. Wipe off any such
chemical agents or fl uids using a soft
cloth immediately.
 


 High water temperature and high water
pressure car washers are available
depending on the type of high pressure
car washer device. If the car washer
nozzle is put too close to the vehicle or
aimed at one area for an extended period
of time, it could deform plastic parts or
damage the paint.
 


 Do not use wax containing compounds
(polish). Otherwise, it could result in
paint damage.
 


 In addition, do not use an electrical or
air tool to apply wax. Otherwise, the
frictional heat generated could result
in deformation of plastic parts or paint
damage.
Interior Care
WARNING
Do not spray water in the cabin:
Splashing water on electrical parts
such as the audio unit and switches
is dangerous as it could cause a
malfunction or a fi re.
Instrument panel Precautions
Prevent caustic solutions such as perfume
and cosmetic oils from contacting the
instrument panel. They will damage and
discolour the instrument panel. If these
solutions get on the instrument panel, wipe
them off immediately.
CAUTION
Do not use glazing agents.
Glazing agents contain ingredients
which may cause discolouration,
wrinkling, cracks and peeling.
Instrument panel top (soft pad)
 




 Extremely soft material is used for the
soft pad surface. When cleaning, it is
recommended that you use a clean towel
dampened in a mild detergent to remove
soiling.
 


 If the soft pad surface is rubbed harshly,
it could result in the surface being
damaged leaving white scratch marks.

If Trouble Arises
Overheating
Overheating
If the High engine coolant temperature
warning light illuminates, the vehicle loses
power, or you hear a loud knocking or
pinging noise, the engine is probably too
hot.
WARNING
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.
Open the bonnet ONLY after steam is
no longer escaping from the engine:
Steam from an overheated engine is
dangerous. The escaping steam could
seriously burn you.
If the High engine coolant temperature
warning light illuminates:
1. Drive safely to the side of the road and
park off the right-of-way.
2. Put a vehicle with an automatic
transaxle in park (P), a manual
transaxle in neutral.
3. Apply the parking brake.
4. Turn off the air conditioner.
5. Check whether coolant or steam is
escaping from the engine compartment.
If steam is coming from the engine
compartment:
Do not go near the front of the vehicle.
Stop the engine.
Wait until the steam dissipates, then
open the bonnet and start the engine.
If neither coolant nor steam is
escaping:
Open the bonnet and idle the engine
until it cools.
CAUTION
If the cooling fan does not operate
while the engine is running, the engine
temperature will increase. Stop the
engine and call an expert repairer,
we recommend an Authorised Mazda
Repairer.
6. Make sure the cooling fan is operating,
then turn off the engine after the
temperature has decreased.
7. When cool, check the coolant level.
If it is low, look for coolant leaks from
the radiator and hoses.

Warning/Indicator Lights and Warning Sounds
Signal Warning
Engine Oil Warning
Light This warning light indicates low engine oil pressure.
CAUTION
Do not run the engine if the oil pressure is low. Otherwise, it could result in
extensive engine damage.
If the light illuminates or the warning indication is displayed while driving:
1. Drive to the side of the road and park off the right-of-way on level ground.
2. Turn off the engine and wait 5 minutes for the oil to drain back into the sump.
3. Inspect the engine oil level 6-29 . If it's low, add the appropriate amount of engine oil
while being careful not to overfi ll.
CAUTION
Do not run the engine if the oil level is low. Otherwise, it could result in extensive
engine damage.
4. Start the engine and check the warning light.
If the light remains illuminated even though the oil level is normal or after adding oil,
stop the engine immediately and have your vehicle towed to an expert repairer, we
recommend an Authorised Mazda Repairer.
(Red)
High Engine Coolant
Temperature Warning
Light
The light fl ashes when the engine coolant temperature is extremely high, and
illuminates when the engine coolant temperature increases further.
Handling Procedure
Flashing light
Drive slowly to reduce engine load until you can fi nd a safe place to stop the vehicle
and wait for the engine to cool down.
Illuminated light
This indicates the possibility of overheating. Park the vehicle in a safe place
immediately and stop the engine.
Refer to Overheating 7-26 .
CAUTION
Do not drive the vehicle with the high engine coolant temperature warning light
illuminated. Otherwise, it could result in damage to the engine.
