Ambient air temperature MAZDA MODEL 3 HATCHBACK 2020 Owners Manual (in English)

Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified value, the system notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data sent
from the tire pressure s
ensors installed on
each wheel via radio signal is received by
the receiver unit in t he vehicle to monitor
the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures can
be checked using the center display.
Refer to the Vehic le Status Monitor
section in the Mazda Connect Owner's
Manual.
NOTE
When the ambient temperature is low,
the tire temperatures also decrease. If
the tire temperatures decrease, the air
pressure in the tires will also decrease
which could turn on the TPMS warning
light.
Before driving, visually inspect the tires
for abnormalities. Additionally, inspect
the tire pressures monthly. A digital type
air pressure gauge is recommended for
inspecting the tire pressures.
The TPMS is not a substitute for your own
periodic inspection of the tires. Always
inspect the tires yourself periodically.
CAUTION
 Each tire, includ ing the spare (if
provided), should be checked monthly
when cold and inflated to the
inflation
pressure recommended by the vehicle
manufacturer on the vehicle placard or
tire inflation pressure label. (If your
vehicle has tires of a different size than
the size indicated on the vehicle placard
or tire inflation pressure label, you should
determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.

Vent Operation
▼Adjusting the Vents
Directing airflow
To adjust the direction of airflow, move
the adjustment knob.
NOTE
When using the air conditioner under
humid ambient temperature conditions,
the system may blow fog from the vents.
This is not a sign of trouble but a result
of humid air being suddenly cooled.
The air vents can be fully opened and
closed by operating the knob.

WA R N I N G
Do not drive the vehicle at high speeds if
the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the
TPMS warning light is turned on or flashing
is dangerous because the brake
performance and the steering wheel
operability will be reduced. If the vehicle is
driven at high speeds or the brakes are
suddenly applied, it could lead to an
accident. Gradually apply the brakes to
lower the vehicle's speed.
Do not ignore the TPMS warning light
when it is turned on or flashing:
Continuing to drive the vehicle while
ignoring the illumination/flashing of the
TPMS warning light is dangerous because a
tire may burst which could lead to an
accident. Take appropriate measures as
soon as possible.
NOTE
While the TPMS is learning the tire
positions, such as immediately after a tire
position has been changed, the tire
pressure at the tire position prior to it
being changed is displayed until the
system completes the learning. For this
reason, the tire pressures displayed for the
tire positions may be different from the
actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressu res to the appropriate
pressures.
Refer to Tire Inflation Pressure on page
6-31.
CAUTION
 Adjust the tire pressures while the tires
are cool. Because the air pressure in the
tires
fluctuates depending on the
temperature, before adjusting the tire
pressures, let the vehicle sit for an hour or
drive it only within a 1.6 km (1 mile)
distance. If the tire pressures are adjusted
while the tires are warm, the tire
pressures may decrease below the specified air pressure after cooling down
which could turn on the warning light. In
addition, because the air pressure in the
tires decreases when the ambient
temperature is low, if the ambient
temperature increases, an illuminated
TPMS warning light may turn off. Under
any circumstances, always adjust the tire
pressures while the tires are cool.
 After adjusting the tire pressures, the
TPMS warning light turns off. If the TPMS
warning light does not turn off, drive the
vehicle at a speed of about 25 km (16
mph) or faster for 3 minutes or longer
and make sure the warning light turns
off.
If the TPMS warning light remains on
even after adjusting th e tire pressures, one
of the tires may have a puncture.
