recommended oil MAZDA MODEL 3 4-DOOR 2018 Owners Manual

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 6-25.
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 6-23).
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
6-27).
NOTE
(Without electric parking brake (EPB))
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 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.
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.
▼ Snow Tires
Use snow tires on all four wheels
Do not go faster than 120 km/h (75 mph)
while driving with sno
w tires. Inflate snow
tires 30 kPa (0.3 kgf/cm
2, 4.3 psi) more
than recommended on the tire pressure
label (driver's door frame), but never more
than the maximum c old-tire pressure
shown on the tires.

Except Mexico (18–inch wheel vehicle)
The vehicle is originally equipped with all
season radials designed to be used all year
around. In some extreme climates you
may find it necessary t o replace them with
snow tires during the winter months to
further improve traction on snow and ice
covered roads.
Mexico (18–inch wheel vehicle)
The vehicle is originally equipped with
summer tires designed for optimum
traction on wet and dry roads. If your
vehicle is to be used on snow and ice
covered roads, Mazda recommends that
you replace the tires originally equipped
on your vehicle with snow tires during the
winter months.

After replacing the engine oil, it is
recommended to have a repair shop such
as an Authorized Mazda Dealer perform
the initialization (engin
e oil data resetting)
of the recorded value. If the value
recorded by the computer is not initialized,
the wrench indicator light may not turn off
or it may turn on earlier than normal.
Refer to Maintenance Monitor on page
6-16.
▼ Inspecting Engine Oil Level
1. Be sure the vehicle is on a level
surface.
2. Warm up the engine to normal operating temperature.
3. Turn it off and wait at least 5 minutes for the oil to retur n to the oil pan.
4. Pull out the dipstic k, wipe it clean, and
reinsert it fully.

▼Upholstery and Synthetic Leather
Maintenance
Fabric
1. Clean the soiled area by lightly
dabbing it with a soft cloth soaked in a
mild detergent (approx. 5%) diluted
with water.
2. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
Synthetic leather
1. Remove dust and sand using a vacuum cleaner.
2. Wipe the soiled area with a soft cloth soaked in a mild detergent (approx.
5%) diluted with water.
3. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
▼Leather Upholstery Maintenance*
1. Remove dust and sand using a vacuum
cleaner.
2. Wipe off the soiled area with a soft
cloth and a suitable, special cleaner or
a soft cloth soaked in a mild detergent
(about 5%) diluted with water.
3. Wipe off the remaining detergent using a cloth soaked in clean water and
wrung out well.
4. Remove moisture with a dry, soft cloth and allow the leather to further dry in a
well-ventilated, shaded area. If the
leather gets wet such as from rain,
remove the moisture and dry it as soon
as possible.
NOTE
Because genuine leather is a natural
material, its surface is not uniform and
it may have natural scars, scratches,
and wrinkles.
To maintain the quality for as long as
possible, periodical maintenance, about
twice a year, is recommended.
If the leather upholstery comes into
contact with any of the following, clean
it immediately.
Leaving it uncleaned could cause
premature wear, mold, or stains.
Sand or dirt
Grease or oil, such as hand cream
Alcohol, such as in cosmetic or hair
dressing items
If the leather upholstery gets wet,
promptly remove moisture with a dry
cloth. Remaining moisture on the
surface may cause deterioration such as
hardening and shrinkage.
Exposure to direct sunlight for long
periods may cause deterioration and
shrinkage. When parking the car under
direct sunlight for long periods, shade
the interior using sunshades.
Do not leave vinyl products on the
leather upholstery for long periods.
They may affect the leather quality and
coloring. If the cabin temperature
becomes hot, the vinyl may deteriorate
and adhere to the genuine leather.

3. Install the lug nuts with the bevelededge inward; tighten them by hand.

WARNING
Do not apply oil or grease to lug nuts
and bolts and do not tighten the lug
nuts beyond the recommended
tightening torque:
Applying oil or grease to lug nuts and
bolts is dangerous. The lug nuts could
loosen while driving and cause the tire
to come off, resulting in an accident. In
addition, lug nuts and bolts could be
damaged if tightened more than
necessary.
4. Turn the lug wrench counterclockwise and lower the vehicle.
5. Use the lug wrench to tighten the nuts
in the order shown.

If you are unsure of how tight the nuts
should be, have them inspected at an
Authorized Mazda Dealer.
Nut tightening torque
N·m (kgf·m, ft·lbf) 108―147 (12―14,
80―108)
WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug nuts
are dangerous. The wheel could wobble
or come off. This could result in loss of
vehicle control and cause a serious
accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration:
Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the stud,
which could cause the wheel to slip off
and cause an accident.
