SignalWarning
(Flashing)
Tire Pressure Moni-
toring System Warn-
ing Light
*
If the tire pressure m onitoring system has a malfunction, the t ire pressure warning light
flashes for about 1 minute when the ignition is switched ON and then continues illuminat-
ing. Have your vehicle checked by an Authorized Mazda Dealer 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 dangerous to drive the vehicle at high speeds, or
perform sudden maneuvering or braking. Vehicl e 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.

KEY Warning Light If any malfunction occurs in the keyless entry system, it illum
inates continuously.
CAUTION
If the key warning indicator light illuminates or the push button start indicator light (am‐
ber) flashes, the engine may not start. If the en gine cannot be started, try starting it using
the emergency operation for starting the engine , and have the vehicle inspected at an Au‐
thorized Mazda Dealer as soon as possible.
Refer to Emergency Operation for Starting the Engine on page 4- 10.
Security Indicator
Light If the engine does not start with the correct key, and the secu
rity indicator light remains
illuminated or flashing, try the following:
Make sure the key is within the operational range for signal transmission. Switch the igni-
tion off, and then restart the e ngine. If the engine does not s tart after 3 or more tries, con-
tact an Authorized Mazda Dealer.

The light remains turned on if th ere is a problem with the system. Have your vehicle in-
spected at an Authorized Mazda Dealer.
NOTE
If the windshield area in fr ont of the Forward Sensing Camera (FSC) is fogged or ob-
structed, the light turns on temporarily. If the light remains turned on, there may be a
problem with the system.

Tire Pressure Monitoring
System
Wa r n i n g
Light
*
When the warning light illuminates, and the
warning beep sound is heard (about 3 seconds),
tire pressure is too low in one or more tires.
WA R N I N G
If the tire pressure monitoring system warning
light illuminates or flashes, or the tire pressure
warning beep sound is heard, decrease vehicle
speed immediately and avoid sudden maneuver‐
ing and braking:
If the tire pressure monitoring system warning
light illuminates or
flashes, or the tire pressure
warning beep sound is heard, it is dangerous to
drive the vehicle at high speeds, or perform sud‐
den maneuvering 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 sy stem monitored again
by an Authorized Mazda Dealer or a tire repair
station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warn ing 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 situation that
could lead to tire failure and a dangerous acci‐
dent. Inspect the tires and adjust to the specified in-
flation pressure (page 6-38).
NOTE
Perform tire pressure adjustment when the
tires are cold. Tire pressure will vary accord-
ing to the tire temperature, therefore let the ve-
hicle stand for 1 hour or only drive it 1.6 km (1
mile) or less before ad
justing the tire pres-
sures. When pressure is adjusted on hot tires to
the cold inflation pressure, the TPMS warning
light/beep may turn on af ter the tires cool and
pressure drops below specification.
Also, an illuminated TPMS warning light, re-
sulting from the tire air pressure dropping due
to cold ambient temper ature will remain illu-
minated even if the ambient temperature rises.
In this case, it will also be necessary to adjust
the tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air pres-
sure, make sure to check and adjust the tire air
pressures.
Tires lose air naturally over time and the
TPMS cannot tell if the tires are getting too
soft over time or yo u have a flat. However,
when you find one low tir e 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 side-
wall. Put a few drops of water in the valve
stem to see if it bubble s indicating a bad valve.
Leaks need to be addressed by more than sim-
ply reinflating the tire as leaks are dangerous
― take it to an Authorized Mazda Dealer.
