2019 MAZDA MODEL 3 HATCHBACK wheel size

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.

Dynamic Stability Control(DSC)
▼Dynamic Stability Control (DSC)
The Dynamic Stability Control (DSC)
automatically controls braking and engine
torque in conjunction with systems such as
ABS and TCS to help control side slip
when driving on slippery surfaces, or
during sudden or evasive maneuvering,
enhancing vehicle safety.

Refer to ABS (page 4-74) and TCS (page
4-75).

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 I ndication/Indicator
Light (Turns on) on page 7-31.
WA R N I N G
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
specified 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 w ith the DSC, the Hill
Launch Assist (HLA) may not operate.
Refer to Hill Launch Assist (HLA) on page
4-72.
▼ TCS/DSC Indicator Light
This indicator light stays on for a few
seconds when the ignition is switched ON.
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.

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

around the vehicle with the mirrors and
directly with your eyes when driving.
The 360°View Monitor is an auxiliary device
which assists the driver in checking the
safety of the area around the vehicle.
The shooting range of the cameras and
detection range of the sensors are limited.
For example, the areas in black at the front
and rear of the vehicle image and the
seams where each of the camera images
merge are blind spots where an obstruction
may not be visible. In addition, the
extended vehicle widt h lines and projected
vehicle path lines are only to be used as
references, and the images on the screen
may differ from the actual conditions.
CAUTION
