Driving Tips
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, transaxle 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
from 1 (D) to R.
Winter Driving
Carry emergency gear, including tyre
chains, window scraper, fl ares, 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:
 


 Have the proper ratio of antifreeze in the
radiator.
  Refer to Engine Coolant on page 6-30 .



 Inspect the battery and its leads. Cold
reduces battery capacity.
 


 Use an engine oil appropriate for the
lowest ambient temperatures that the
vehicle will be driven in (page 6-23 ).
 


 Inspect the ignition system for damage
and loose connections.
 


 Use washer fl uid made with antifreeze—
but do not use engine coolant antifreeze
for washer fl uid (page 6-34 ).
NOTE

 Do not use the parking brake in
freezing weather as it may freeze.
Instead, shift to P with an automatic
transaxle and to 1 or R with a manual
transaxle. Block the rear wheels.
  Remove snow before driving. Snow
left on the windscreen is dangerous
as it could obstruct vision.
  Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windscreen.

Switches and Controls
NOTE

 If an indicator light stays on without
fl ashing or if it fl ashes abnormally,
one of the direction indicator bulbs
may be burned out.
  A personalised function is available
to change the turn indicator sound
volume. (page 9-16 )
Lane-Change Signals
Move the lever halfway toward the
direction of the lane change—until the
indicator fl ashes— and hold it there. It will
return to the off position when released.
Three-Flash Turn Signal *
After releasing the direction indicator
lever, the direction indicator fl ashes three
times. The operation can be cancelled by
moving the lever in the direction opposite
to which it was operated.
NOTE
The three-fl ash turn signal function can
be switched to operable/inoperable using
the personalisation function.
Refer to Personalisation Features on
page 9-16 .
Windscreen Wipers and
Washer
The ignition must be switched ON to use
the wipers.
WARNING
Use only windscreen washer fl uid or
plain water in the reservoir:
Using radiator antifreeze as washer
fl uid is dangerous. If sprayed on the
windscreen, it will dirty the windscreen,
affect your visibility, and could result in
an accident.
Only use windscreen washer fl uid
mixed with anti-freeze protection in
freezing weather conditions:
Using windscreen washer fl uid without
anti-freeze protection in freezing
weather conditions is dangerous as it
could freeze on the windscreen and
block your vision which could cause
an accident. In addition, make sure
the windscreen is suffi ciently warmed
using the defroster before spraying the
washer fl uid.

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.

Maintenance and Care
Owner Maintenance
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.
