2022 MAZDA MODEL MX-30 EV tire size

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 Coolant on page 6-11.
Inspect the lead-acid battery and its
cables. Cold reduces battery
capacity.
Inspect the EV system for damage
and loose connections.
Use washer fluid made with
antifreeze ―but do not use coolant
antifreeze for washer fluid (page
6-13).
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 a ffected 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 4 wheels
Do not go faster than 120 km/h (75
mph) while driving with snow tires.
In
flate snow tires 30 kPa (0.3 kgf/cm
2,
4.3 psi) more than recommended on
the tire pressure label (rear door on the
driver's side), but never more than the
maximum cold-tire pressure shown on
the tires.

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 to
replace them with snow tires during
the winter months to further improve
traction on snow and ice covered
roads.
WARNING
Use only the same size and type tires
(snow, radial, or non-radial) on all 4
wheels:
Using tires di fferent in size or type is
dangerous. Your vehicle's handling
could be greatly aff ected 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 reinforcement in
the sidewalls (page 4-181).
▼ Tire Chains
Check local regulations before using
tire chains.

Dynamic Stability Control(DSC)
▼Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and
motor torque in conjunction with
systems such as the ABS and TCS to
help control side slip when driving on
slippery surfaces, or during sudden or
evasive steering, which enhances
vehicle stability.

Refer to ABS (page 4-63) and TCS
(page 4-64).

DSC operation is possible at speeds
greater than 20 km/h (12 mph).

The warning light turns on when the
system has a malfunction.
Refer to TCS/DSC Indication/
Indicator Light (Turns on) on page
7-27.
WARNING
Do not rely on the Dynamic Stability
Control as a substitute for safe
driving:
The Dynamic Stability Control (DSC)
cannot compensate for unsafe and
reckless driving , excessive speed,
tailgating (following another vehicle
too closely), and hydroplaning
(reduced tire friction and road contact
because of water on the road surface).
You can still have an accident.
CAUTION

The DSC may not operate correctly
unless the following are observed:
 Use tires of the correct size
speci fied for your Mazda on all 4
wheels.
 Use tires of the same
manufacturer, brand and tread
pattern on all 4 wheels.
 Do not mix worn tires.
 The DSC may not operate correctly
when tire chains are used or a
temporary spare tire is installed
because the tire diameter changes.
NOTE
If there is a problem with the DSC, the
Hill Launch Assi st (HLA) may not
operate.
Refer to Hill Launch Assist (HLA) on
page 4-61.
▼ TCS/DSC Indicator Light
When the power switch is switched
ON, the TCS/DSC indicator light turns
on and then turns
off after a few
seconds. If the TCS or DSC is
operating , the indicator light flashes.

If the light stays on, the TCS, DSC or
the brake assist system may have a
malfunction and they may not operate
correctly. Take your vehicle to an
Authorized Mazda Dealer.

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 (yellow 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 electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display and the
active driving display.

Use the system when you drive the
vehicle on roads with white (yellow)
lines such as expressways and
highways.
WARNING
Do not rely completely on the LAS
:
 The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a
driver’s lack of caution, and
over-reliance on the system could
lead to an accident.
The functions of the LAS have
limitations. Always stay on course
using the steering wheel and drive
with care.
 Do not use the LAS under the
following circumstances, otherwise it
may result in an accident.
 The vehicle is driven on slippery
roads such as icy or snow-covered
roads, and unpaved roads.
 Tires of a
different
speci fied size
are used, such as a temporary
spare tire.
 The vehicle is being used to tow a
camper or boat trailer.
 Tire chains are used.
 The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.
NOTE
The system may not operate normally
under the following conditions.
A condition under which the forward
sensing camera (FSC) cannot detect
a target object is met.
Refer to Forward Sensing Camera
(FSC) on page 4-71.
The visibility of white (yellow) lines is
poor (due to paint flaking or dirt, or
being hidden by vehicles ahead).
There are multiple white (yellow)
lines or they are interrupted.
A misleading line on the road is
picked up (such as temporary line for
construction, shadow, lingering
snow, or grooves filled with water).
The width of a lane is excessively
narrow.
The vehicle is shaken after hitting a
road bump.
The vehicle is driven on a section
with a closed lane or temporary lane
due to construction.
