tire pressure MAZDA MODEL 3 SEDAN 2019 Owners Manual

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 6-17.
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 6-15).
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
6-19).
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.
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.

Mexico
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.
Except Mexico
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.

WA R N I N G
Use only the same size and type tires (snow,
radial, or non-radial) on all four wheels:
Using tires different in size or type is
dangerous. Your vehi cle's handling could
be greatly affected and result in an
accident.
CAUTION
Check local regulations before using
studded tires.
NOTE
The tire pressure monitoring system may
not function correctly when using tires
with steel wire re inforcement in the
sidewalls (page 4-215).
▼ Tire Chains
Check local regulations before using tire
chains.
CAUTION

Chains may
affect handling.
 Do not go faster than 50 km/h (30 mph)
or the chain manufacturer's
recommended limit, whichever is lower.
 Drive carefully and avoid bumps, holes,
and sharp turns.
 Avoid locked-wheel braking.
 Do not use chains on a temporary spare
tire; it may result in damage to the
vehicle and to the tire.
 Do not use chains on roads that are free
of snow or ice. The tires and chains could
be damaged.
Chains may scratch or chip aluminum
wheels.
NOTE
The tire pressure monitoring system may
not function correctly when using tire
chains.
Install the chains on the front tires only.
Do not use chains on the rear tires.
Please consult an Authorized Mazda
Dealer.
Installing the chains
1. If your vehicle is equipped with wheel
covers remove them, otherwise the
chain bands will scratch them.
2. Secure the chains on the front tires as tightly as possible.
Always follow the chain
manufacturer's instructions.
3. Retighten the chains after driving 1/2―1 km (1/4―1/2 mile).

i-ACTIV AWD Operation*
▼i-ACTIV AWD Operation
AWD provides excellent drivability on
snow-covered and ice-packed roads, sand
and mud, as well as on steep slopes and
other slippery surfaces.
A system malfunction or operation
conditions are indicated by a warning.
Refer to Contact Authorized Mazda
Dealer and AWD Warning Indication/
Warning Light on page 7-30.
WA R N I N G
Never spin a wheel that is
off the ground:
Spinning a wheel that is off the ground as a
result of the vehicle being stuck or in a
ditch is dangerous. The drive assembly
could be seriously damaged which could
lead to an accident or could even lead to
overheating, oil leakage, and a fire.
▼ AWD Driving
This vehicle has not been designed for the
purpose of off-road driving or rallies. Do
not attempt to drive over uneven or rocky
surfaces, or across rivers.
Although this vehicle is equipped with
AWD, acceleration, steering and braking
operations should be conducted in the
same manner as with a non-AWD vehicle,
with the emphasis placed on safe driving.
▼Tires and Tire Chains
The condition of the tires plays a large role
in the performance
of the vehicle.
Moreover, to prevent adverse effects to the
drive assembly, please note the following:
Tires
When replacing tires, always replace all
front and rear tires at the same time.
All tires must be of the same size,
manufacture, brand and tread pattern.
Pay particular attention when equipping
snow or other types of winter tires.
Do not mix tread-worn tires with normal
tires.
Inspect tire inflation pressures at the
specified periods adjust to the specified
pressures.
NOTE
Check the tire inflation pressure label
attached to driver's door frame for the
correct tire inflation pressure.
Make sure to equip the vehicle with
genuine wheels of the specified size, on
all wheels. With AWD, the system is
calibrated for all 4 wheels being of the
same dimensions.
Tire chains
Install tire chains to the front tires.
Do not use tire chains on the rear
wheels.
Do not drive the veh icle faster than 30
km/h (19 mph) with the tire chains
installed.
Do not drive the vehicle with tire chains
on road conditions other than snow or
ice.
▼ To w i n g
If the vehicle requires towing, have it
towed with all 4 wheels completely off the
ground.

Lane Departure WarningSystem (LDWS)
*
▼Lane Departure Warning System
(LDWS)
The LDWS alerts the driver that the
vehicle may be deviating from its lane. If
the white (yellow) lin
es on the traffic lane
are detected using the Forward Sensing
Camera (FSC) and the system determines
that the vehicle may be deviating from its
lane, it notifies the driver by flashing the
LDWS warning light and activating the
LDWS warning beep, and by the
multi-information display.
Refer to Forward Sen sing Camera (FSC)
on page 4-198.
Use the LDWS when you drive the vehicle
on roads with white (yellow) lines.

Lane-keep Assist System(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle lane
if the vehicle might be deviating.
The forward sensing camera (FSC) detects
the white lines (ye
llow lines) of the
vehicle lane in which the vehicle is
traveling and if the system determines that
the vehicle may deviate from its lane, it
operates the electri c power steering to
assist the driver’s steering operation. The
system also alerts the driver by displaying
an alert on the mult i-information display
or the active driving display
*. Use the
system when you drive the vehicle on
roads with white (ye llow) lines such as
expressways and highways.
