Improper or incomplete service may
result in problems. This section gives
instructions only for items that are easy
to perform.

As explained in the Introduction (page
6-2), several procedures can be done
only by a
qualified service technician
with special tools.

Improper do-it yourself maintenance
during the warranty period may affect
warranty coverage. For details, read the
separate Mazda Warranty statement
provided with the vehicle. If you are
unsure about any servicing or
maintenance procedure, have it done
by an expert repairer (we recommend
an Authorised Mazda Repairer).

There are strict environmental laws
regarding the disposal of waste oil and
fluids. Please dispose of your waste
properly and with due regard to the
environment.

We recommend that you entrust the oil
and fluid changes of your vehicle to an
expert repairer (we recommend an
Authorised Mazda Repairer).
WARNING
Do not perform maintenance work if
you lack sufficient knowledge and
experience or the proper tools and
equipment to do the work. Have
maintenance work done by a
qualified 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, loose clothing or
have long hair or a long beard.
Either can become entangled in
moving parts and result in injury.

NOTE
(SKYACTIV-D 1.8)
When inspecting the engine oil
level, pull out the dipstick straight
without twisting. In addition, when
inserting the dipstick, always insert
it without twisting so that the “X”
mark faces the front of the vehicle.
6. 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.
7. Make sure the O-ring on the
dipstick is positioned properly
before reinserting the dipstick.
8. 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.
Maintenance and Care
Owner Maintenance
6-28

NOTE
If the replacement is not done using
the correct procedure indicated in the
service manual, it could cause an
engine malfunction. Consult an expert
repairer (we recommend an
Authorised Mazda Repairer) for
details.
Inspect the antifreeze protection and
coolant level in the coolant reservoir at
least once a yearŠat the beginning of
the winter seasonŠand 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 FULL and
LOW marks on the coolant reservoir
when the engine is cool.

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
¾Radiator coolant will damage paint.
Rinse it off quickly if spilled.
¾If 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

▼Plastic Part Maintenance
xWhen cleaning the plastic lenses of
the lights, do not use petrol, paraffin,
rectified spirit, paint, thinner, highly
acidic detergents, or strongly alkaline
detergents. Otherwise, these
chemical agents can discolour or
damage the surfaces resulting in a
significant loss in functionality. If
plastic parts become inadvertently
exposed to any of these chemical
agents, flush with water immediately.
xIf plastic parts such as the bumpers
become inadvertently exposed to
chemical agents or fluids such as
petrol, oil, engine coolant, or battery
fluid, it could cause discolouration,
staining, or paint peeling. Wipe off
any such chemical agents or fluids
using a soft cloth immediately.
xHigh 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.
xDo not use wax containing
compounds (polish). Otherwise, it
could result in paint damage.
xIn 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
▼Interior Care
WARNING
Do not spray water into the vehicle
cabin:
Spraying water into the vehicle cabin is
dangerous as electrical devices such as
the audio and switches could get wet
resulting in a malfunction or vehicle
fire.
NOTE
xDo not wipe the interior using
alcohol, chlorine bleach, or organic
solvents such as thinner, benzene,
and petrol. Otherwise, it may cause
discolouration or stains.
xRubbing hard with a stiff brush or
cloth may cause damage.
If the vehicle interior becomes soiled
by any of the following , wipe it off
immediately using a soft cloth.
Leaving it uncleaned could cause
discolouration, stains, cracks, or
peeling of the coating , and it will make
it hard to wipe off later.
xBeverage or fragrancexGrease or oilxSoiling
▼Seat Belt Maintenance
1. Clean the soiled area by lightly
dabbing it with a soft cloth soaked
in a mild detergent (approx. 5%)
diluted with water.
2. Wipe off the remaining detergent
using a cloth soaked in clean water
and wrung out well.

Overheating
▼Overheating
If the engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed, the
vehicle loses power or you hear a loud
knocking or pinging noise, the engine
is probably too hot.
WARNING
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.
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 engine coolant temperature
gauge indicates overheating and the
high engine coolant temperature
warning indication is displayed:

1. Drive safely to the side of the road
and park off the right-of-way.
2. Put a vehicle with an automatic
transmission in park (P), a manual
transmission 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.

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 (page
6-27). If it's low, add the
appropriate amount of engine oil
while being careful not to overfill.
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).
▼High Engine Coolant Temperature
Warning Indication
Displays if the engine coolant
temperature has increased excessively.
“Elevated Engine Coolant Temp. Drive
Slowly” displayed
Drive slowly to reduce engine load
until you can find a safe place to stop
the vehicle and wait for the engine to
cool down.
“Excessive Engine Coolant Temp. Stop
the Vehicle in a Safe Location”
displayed
This indicates the possibility of
overheating. Park the vehicle in a safe
place immediately and stop the
engine.
Refer to Overheating on page 7-44.
CAUTION
Do not drive the vehicle with the high
engine coolant temperature warning
light illuminated. Otherwise, it could
result in damage to the engine.
▼Power Steering Malfunction
Indication/Indicator Light
The message is displayed if the electric
power steering has a malfunction.
If the message is displayed, stop the
vehicle in a safe place and do not
