Before Driving
Driving Tips
Winter Driving
Carry emergency gear, including tyre
chains, window scraper, À 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
6-27 .
 


 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 6-22 ).




 Inspect the ignition system for damage
and loose connections.
 


 Use washer À uid made with antifreeze—
but do not use engine coolant antifreeze
for washer À uid (page 6-30 ).

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.
  Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
  Drive slowly. Braking performance
can be adversely affected if
snow or ice adheres to the brake
components. If this situation occurs,
drive the vehicle slowly, releasing
the accelerator pedal and lightly
applying the brakes several times
until the brake performance returns
to normal.

When Driving
Switches and Controls
NOTE
  If an indicator light stays on without
À ashing or if it À 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 9-13 )
Lane-Change Signals
Move the lever halfway toward the
direction of the lane change—until the
indicator À 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 À ashes three
times. The operation can be cancelled by
moving the lever in the direction opposite
to which it was operated.
NOTE
The three-À ash turn signal function can
be switched to operable/inoperable using
the personalisation function.
Refer to Personalisation Features on
page 9-13 .
Windscreen Wipers and
Washer
The ignition must be switched ON to use
the wipers.
WARNING
Use only windscreen washer À uid or
plain water in the reservoir:
Using radiator antifreeze as washer
À 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 À uid
mixed with anti-freeze protection in
freezing weather conditions:
Using windscreen washer À 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 suf¿ ciently warmed
using the defroster before spraying the
washer À uid.

CAUTION
Heed the following precautions to assure correct operation of each system.  
 Do not adhere stickers (including transparent stickers) to the surface of the radiator
grille and front emblem in and around the radar sensor (front), and do not replace
the radiator grille and front emblem with any product that is not a genuine product
designed for use with the radar sensor (front).
  The radar sensor (front) includes a function for detecting soiling of the radar sensor's
front surface and informing the driver, however, depending on the conditions, it may
require time to detect or it may not detect plastic shopping bags, ice or snow. If this
occurs, the system may not operate correctly, therefore always keep the radar sensor
(front) clean.
  Do not install a grille guard. 
 If the front part of the vehicle has been damaged in a vehicle accident, the position of
the radar sensor (front) may have moved. Stop the system immediately and always
have the vehicle inspected at an Authorised Mazda Repairer.
  Do not use the front bumper to push other vehicles or obstructions such as when
pulling out of a parking space. Otherwise, the radar sensor (front) could be hit and its
position deviated.
  Do not remove, disassemble, or modify the radar sensor (front). 
 For repairs, replacement or paint work around the radar sensor (front), consult an
Authorised Mazda Repairer.
  Do not modify the suspension. If the suspension are modi¿ ed, the vehicle's posture
could change and the radar sensor (front) may not be able to correctly detect a vehicle
ahead or an obstruction.

Engine Coolant
Inspecting Coolant Level
WARNING
Do not use a match or live À 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.


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 inde¿ 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 or FULL and
L marks on the coolant reservoir when the
engine is cool.

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 or FULL.
Securely tighten the coolant reservoir tank
cap after adding coolant.
CAUTION
  Radiator coolant will damage paint.  Rinse it off quickly if spilled. 

 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.

Washer Fluid
Inspecting Washer Fluid Level
WARNING
Use only windscreen washer À uid or
plain water in the reservoir:
Using radiator antifreeze as washer
À uid is dangerous. If sprayed on the
windscreen, it will dirty the windscreen,
affect your visibility, and could result in
an accident.
Inspect À uid level in the washer À uid
reservoir; add À uid if necessary.


E

Use plain water if washer À uid is
unavailable.
But use only washer À uid in cold weather
to prevent it from freezing.
NOTE
Front and rear washer À uid is supplied
from the same reservoir.
Body Lubrication
All moving points of the body, such as
door and bonnet hinges and locks, should
be lubricated each time the engine oil is
changed. Use a nonfreezing lubricant on
locks during cold weather.

Make sure the bonnet's secondary latch
keeps the bonnet from opening when the
primary latch is released.
