engine MAZDA MODEL 6 2020 Owner's Manual (in English)

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.
SKYACTIV-G 2.5

SKYACTIV-G 2.5T

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 c oolant 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/Clutch Fluid
▼ Inspecting Brake/Clutch Fluid Level
WA R N I N G
If the brake/clutch fluid level is low, have
the brakes inspected:
A low brake/clutch
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.
The brakes and clutch draw fluid from the
same reservoir.
Inspect the fluid level in the reservoir
regularly. It should be kept between the
MAX and MIN lines.
The level norm ally drops with
accumulated distance, a condition
associated with wear of brake and clutch
linings. If it is excessively low, have the
brake/clutch system inspected by an
Authorized Mazda Dealer.

If the above indications remain
unchanged even after 1 minute has
passed with the vehicle stopped:
If you have already added 5.7 L (1.5 US
gal, 1.3 Imp gal) of DEF according to
the DEF level (%) indication on the
multi-information di splay, prepare an
additional 5.7 L (1.5 US gal, 1.3 Imp
gal) of DEF or more and add it
following the replenishment procedure.
If you added the correct amount of DEF,
the DEF level (%) indication on the
multi-information di splay will show an
increase while the vehicle is being
driven. If the DEF l evel (%) shows no
increase or the speed restriction does not
cancel even while dri ving the vehicle,
consult an Authorized Mazda Dealer.
Body Lubrication
All moving points of the body, such as
door and hood 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 hood's secondary latch
keeps the hood from opening when the
primary latch is released.

WARNING
Do not replace the main fuse by
yourself. Have an Authorized Mazda
Dealer perform the replacement:
Replacing the fuse by yourself is
dangerous because the MAIN fuse is a
high current fuse. Incorrect
replacement could cause an electrical
shock or a short circuit resulting in a
fire.

Wa t e r M a r k s
Occurrence
Rain, fog, dew, and even tap water can
contain harmful minerals such as salt and
lime. If moisture containing these minerals
settles on the vehicle and evaporates, the
minerals will concentrate and harden to
form white rings. The rings can damage
your vehicle's finish.
Prevention
It is necessary to wash and wax your
vehicle to preserve its finish according to
the instructions in this section. These steps
should be taken immediately after you find
water marks on your vehicle's finish.
Paint Chipping
Occurrence
Paint chipping occurs when gravel thrown
in the air by another vehicle's tires hits
your vehicle.
How to avoid paint chipping
Keeping a safe distance between you and
the vehicle ahead reduces the chances of
having your paint chipped by flying
gravel.
NOTE
The paint chipping zone varies with the
speed of the vehicle. For example, when
traveling at 90 km/h (56 mph), the paint
chipping zone is 50 m (164 ft).
In low temperatures a vehicle's finish
hardens. This increases the chance of
paint chipping.
Chipped paint can lead to rust forming
on your Mazda. Before this happens,
repair the damage by using Mazda
touch-up paint according to the
instructions in this section. Failure to
repair the affected area could lead to
serious rusting and expensive repairs.

Follow all label and container directions
when using a chemical cleaner or polish.
Read all warnings and cautions.
▼ Maintaining the Finish
Wa s h i n g
CAUTION

When the wiper lever is in the AUTO
position and the ignition is switched ON,
the wipers may move automatically in
the following cases:
 If the windshield above the rain sensor
is touched or wiped with a cloth.
 If the windshield is struck with a hand
or other object from either outside or
inside the vehicle.
Keep hands and scrapers clear of the
windshield when the wiper lever is in the
AUTO position and the ignition is
switched ON as fingers could be pinched
or the wipers and wiper blades damaged
when the wipers activate automatically.
If you are going to clean the windshield,
be sure the wipers are turned off
completely (when it is most likely that the
engine is left running) this is particularly
important when clearing ice and snow.

Do not spray water in the engine
compartment. Otherwise, it could result
in engine-starting problems or damage
to electrical parts.
 When washing and waxing the vehicle,
be careful not to apply excessive force to
any single area of the vehicle roof or the
antenna. Otherwise, you could dent the
vehicle or damage the antenna.
To help protect the finish from rust and
deterioration, wash your Mazda
thoroughly and frequently, at least once a
month, with lukewarm or cold water.

If the vehicle is washed improperly, the
paint surface could be scratched. Here are
some examples of how scratching could
occur.

Scratches occur on th e paint surface when:
The vehicle is washed without first
rinsing off dirt and other foreign matter.
The vehicle is washed with a rough, dry,
or dirty cloth.
The vehicle is washed at a car wash that
uses brushes that are dirty or too stiff.
Cleansers or wax containing abrasives
are used.
NOTE
Mazda is not responsible for scratches
caused by automatic car washes or
improper washing.
Scratches are more noticeable on
vehicles with darker paint finishes.
To minimize scratches on the vehicle's
paint finish:
Rinse off any dirt or other foreign matter
using lukewarm or cold water before
washing.
Use plenty of luke warm or cold water
and a soft cloth when washing the
vehicle. Do not use a nylon cloth.
Rub gently when washing or drying the
vehicle.
Take your vehicle only to a car wash
that keeps its brushes well maintained.
Do not use abrasive cleansers or wax
that contain abrasives.
CAUTION
 Do not use steel wool, abrasive cleaners,
or strong detergents containing highly
alkaline or caustic agents on
chrome-plated or anodized aluminum
parts. This may damage the protective
coating; also, cleaners and detergents
may discolor or deteriorate the paint.
Pay special attention to removing salt, dirt,
mud, and other forei gn material from the
underside of the fenders, and make sure
the drain holes in the lower edges of the
doors and rocker panels are clean.

Insects, tar, tree sap, bird droppings,
industrial fallout, and similar deposits can
damage the finish if not removed
immediately. When prompt washing with
plain water is ineffective, use a mild soap
made for use on vehicles.
