Rocking the Vehicle
▼Rocking the Vehicle
WARNING
Do not spin the wheels at more than
56 km/h (35 mph), 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 tire could overheat and
explode. This could cause serious
injuries.
CAUTION
Too much rocking may cause engine
overheating , transmission failure, and
tire damage.
If you must rock the vehicle to free it
from snow, sand or mud, depress the
accelerator slightly and slowly move
the selector lever from D to R position.
Winter Driving
▼Winter Driving
Carry emergency gear, including tire
chains, window scraper,
flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Engine Coolant on page
6-19.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
6-16).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze ―but do not use engine
coolant antifreeze for washer fluid
(page 6-21).
NOTE
Remove snow before driving. Snow
left on the windshield 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 windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.

Windshield Wipers andWasher
▼Windshield Wipers and Washer
The ignition must be switched ON to
use the wipers.
WARNING
Use only windshield washer
fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the windshield,
affect your visibility, and could result in
an accident.
Only use windshield washer fluid
mixed with anti-freeze protection in
freezing weather conditions:
Using windshield washer fluid without
anti-freeze protection in freezing
weather conditions is dangerous as it
could freeze on the windshield and
block your vision which could cause an
accident. In addition, make sure the
windshield is sufficiently warmed using
the defroster before spraying the
washer fluid.
CAUTION
 When the wipers are not used during
freezing temperatures or for a long
time, the wiper rubber may adhere
to the glass. If the wipers are
operated while adhered to the glass,
it could damage the wiper rubber
and motor.
 If the wipers are operated while the
glass is dry, the glass could be
scratched and the wiper rubber
damaged. When the glass is dry,
spray washer
fluid before operating
the wipers.
 If the amount of washer fluid spray is
insufficient, do not use the washer
switch. If the washer switch
continues to be operated with no
washer fluid being sprayed, it could
lead to pump damage.
NOTE
If the windshield wipers are operated
under cold weather conditions or
during snowfall, they could stop due to
accumulated snow on the windshield.
If the windshield wipers stop due to
accumulated snow on the windshield,
park the vehicle in a safe place, turn
the wiper switch off, and then remove
the accumulated snow. If the wiper
switch is turned to another position
other than OFF, the wipers will
operate. If the wipers do not operate
even though the wiper switch is turned
to a position other than OFF, consult
an Authorized Mazda Dealer as soon
as possible.

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.
NOTE
Changing the coolant should be done
by an Authorized Mazda Dealer.
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
traveling 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.

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.
 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 Authorized Mazda Dealer.
Brake Fluid
▼ Inspecting Brake Fluid Level
WARNING
If the brake fluid level is low, have the
brakes inspected:
A low brake
fluid level is dangerous.
A low level could indicate brake lining
wear or a brake system leak which
could cause the brakes to fail and lead
to an accident.
Inspect the fluid level in the reservoir
regularly. It should be kept between
the MAX and MIN lines.
The level normally drops with
accumulated distance, a condition
associated with wear of brake linings. If
it is excessively low, have the brake
system inspected by an Authorized
Mazda Dealer.

Washer Fluid
▼Inspecting Washer Fluid Level
WARNING
Use only windshield washer fluid or
plain water in the reservoir:
Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will
dirty the windshield,
affect your visibility, and could result in
an accident.
Using Washer Fluid Without
Anti-freeze Protection in Cold
Weather:
Operating your vehicle in temperatures
below 4 °C (40 °F) using washer fluid
without anti-freeze protection is
dangerous as it could cause impaired
windshield vision and result in an
accident. In cold weather, always use
washer fluid with anti-freeze
protection.
NOTE
State or local regulations may restrict
the use of volatile organic compounds
(VOCs), which are commonly used as
anti-freeze agents in washer fluid. A
washer fluid with limited VOC content
should be used only if it provides
adequate freeze resistance for all
regions and climates in which the
vehicle will be operated.
Inspect fluid level in the washer fluid
reservoir; add fluid if necessary.
1. L

Use plain water if washer fluid is
unavailable.
But use only washer fluid in cold
weather to prevent it from freezing.
NOTE
Front and rear washer fluid is supplied
from the same reservoir.

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 hood 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. Shift into park (P).
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 hood and start the
engine.

If neither coolant nor steam is
escaping:
Open the hood 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
Authorized Mazda Dealer.
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.

If you find a leak or other damage, or
if coolant is still leaking:
Stop the engine and call an Authorized
Mazda Dealer.
