2020 MAZDA MODEL MX-5 tire pressure

25. The emergency flat tire repair iscompleted successfully if the tire
inflation pressure does not decrease.
Carefully drive the vehicle to the
nearest Authorized Mazda Dealer
immediately and have the flat tire
replaced. Replacement with a new tire
is recommended. If the tire is to be

flat tire repair kit, Mazda
recommends that the tire be replaced
with a new one as soon as possible.
If the tire is to be repaired or reused,
consult an Authorized Mazda
Dealer.
The wheel can be reused if the
sealant adhering to it is removed.
However, replace the valve with a
new one.
▼Inspecting the Emergency Flat Tire
Repair Kit
Inspect the emergency flat tire repair kit at
regular intervals.
Check the tire sealant period of effective
use.
Check the operation of the tire
compressor.
NOTE
The tire sealant has a period of effective
use. Check the period of effective use
indicated on the bottle label and do not
use it if it has expired. Have the tire

3. Place the lug wrench on top of the keyand apply pressure. Turn the wrench
counterclockwise.
To install the antitheft lug nut
1. Place the special key on top of the nut, and be sure to hold the key square to it.
If you hold the key at an angle, you
may damage both key and nut. Do not
use a power impact wrench.
2. Place the lug wrench on top of the
special key, apply pressure, and turn it
clockwise.

▼Mounting the Tire
1. Remove dirt and grime from themounting surfaces of the wheel and
hub, including the hub bolts, with a
cloth.

WARNING
Make sure the mounting surfaces of the
wheel, hub and lug nuts are clean
before changing or replacing tires:
When changing or replacing a tire, not
removing dirt and grime from the
mounting surfaces of the wheel, hub
and hub bolts is dangerous. The lug
nuts could loosen while driving and
cause the tire to come off, resulting in
an accident.
2. Mount the tire.
3. Install the lug nuts with the beveled edge 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 counterclockwiseand 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.
6. Remove the tire blocks and store the tools and jack.
7. Check the inflation pressure. Refer to Tires on page 9-8.
WARNING
Do not drive with any tires that have
incorrect air pressure:
Driving on tires with incorrect air pressure
is dangerous. Tires with incorrect pressure
could affect handling and result in an
accident. When you check the regular tires'
air pressure, check the spare tire, too.
NOTE
To prevent the jack and tool from rattling,
store them properly.

SignalWarning
(Flashing)
Tire Pressure Moni‐ toring System
Warning Light If the tire pressure monitoring s
ystem has a malfunction, the tire pressure warning light
flashes. Have your vehicle checked by an Authorized Mazda Deale r as soon as possible.
WARNING
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, decrease vehicle speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system warning light illuminates or flashes, or the tire pres‐
sure warning beep sound is heard, it is dang erous to drive the vehicle at high speeds, or
perform sudden maneuver ing or braking. Vehicle drivability could worsen and result in an
accident.
To determine if you have a slow leak or a flat, pull over to a safe position where you can
check the visual condition of the tire and determine if you have enough air to proceed to a
place where air may be added and the system monitored again by an Authorized Mazda
Dealer or a tire repair station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it is illuminated. Have
the problem taken care of as soon as possible before it develops into a more serious situa‐
tion that could lead to tire failure and a dangerous accident.

Action to be taken
Inspect the tires and adjust to the specified inflation pressur e (page 6-38).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sensors may be damaged.
NOTE
Perform tire pressure adjustment when the tires are cold. Tire pressure will vary according to the tire temper ‐
ature, therefore let the vehicle stand for 1 hour or only drive it 1.6 km (1 mile) or less before adjusting the
tire pressures. When pressure is adjusted on hot tires to the cold inflation pressure, the TPMS warning light/
beep may turn on after the tires cool and pressure drops below specification.
Also, an illuminated TPMS warning light, resulting from the tire air pressure dropping due to cold ambient
temperature, may turn off if the ambient temperature rises. In this case, it will also be necessary to adjust the
tire air pressures. If the TPMS warnin g light illuminates due to a drop in tire air pressure, make sure to check
and adjust the tire air pressures.
After adjusting the tire air pressures, it may require some time for the TPMS warning light to turn off. If the
TPMS warning light remains illuminate d, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
Tires lose air naturally over time and the TPMS cannot tell if the tires are getting too soft over time or you
have a flat. However, when you find one low tire in a set of four-that is an indication of trouble; you should
have someone drive the vehicle slowly forward so you can inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Put a few drops of water in the valve stem to see if it bubbles indicating a
bad valve. Leaks need to be addressed by more than simply refilling the trouble tire as leaks are dangerous
― take it to an Authorized Mazda Dealer which has all the equipment to fix tires, TPMS systems and order
the best replacement tire for your vehicle.
If the warning light illuminates again even after the tire pressures are adjusted, there may be a tire puncture.

the ignition is not switched OFF and all
the doors are closed, a beep will be heard
in the cabin 6 times.
NOTE
Because the key utilizes low-intensity
radio waves, the Key Removed From
Vehicle Warning may activate if the key is
carried together with a metal object or it
is placed in a poor signal reception area.
▼Request Switch Inoperable Warning
Beep (With the advanced keyless
