Rocking the Vehicle
▼Rocking the Vehicle
WARNING
Do not spin the wheels at high speed,
and do not allow anyone to stand
behind a wheel when pushing the
vehicle:
When the vehicle is stuck, spinning the
wheels at high speed is dangerous. The
spinning tyre could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating , transmission failure, and
tyre damage.
If you must rock the vehicle to free it
from snow, sand or mud, depress the
accelerator slightly and slowly move
the shift lever/selector lever from 1 (D)
to R position.
Winter Driving
▼Winter Driving
Carry emergency gear, including tyre
chains, window scraper,
flares, a small
shovel, jumper leads, and a small bag
of sand or salt.
Ask an expert repairer (we recommend
an Authorised Mazda Repairer) to
check the following:
xHave the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page
6-28.
xInspect the battery and its leads.
Cold reduces battery capacity.
xUse an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
6-24).
xInspect the ignition system for
damage and loose connections.
xUse washer fluid made with
antifreezeŠbut do not use engine
coolant antifreeze for washer fluid
(page 6-31).
NOTE
xRemove snow before driving. Snow
left on the windscreen is dangerous
as it could obstruct vision.
xDo not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windscreen.
xNever use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.

3. MIN

SKYACTIV-D 1.8

1. X Mark
2. MAX
3. OK
4. MIN

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).

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.
If Trouble Arises
Overheating
7-44

If it is low, look for coolant leaks
from the radiator and hoses.

If you find a leak or other damage, or
if coolant is still leaking:
Stop the engine and call an expert
repairer (we recommend an
Authorised Mazda Repairer).
1. Cooling system cap
2. Cooling fan
3. Coolant reservoir

If you find no problems, the engine is
cool, and no leaks are obvious:
Carefully add coolant as required
(page 6-28).
CAUTION
If the engine continues to overheat or
frequently overheats, have the cooling
system inspected. The engine could be
seriously damaged unless repairs are
made. Consult an expert repairer (we
recommend an Authorised Mazda
Repairer).
