SignalWarning Action to be taken
Seat Belt Warning
Light The seat belt warning light turns on if the
driver or passenger's seat is occupied and
the seat belt is not fastened with the ignition
switched ON.
If the driver or passenger's seat belt is un‐
fastened (only when the passenger's seat is
occupied) and the vehicle is driven at a
speed faster than about 20 km/h (12 mph),
the warning light flashes. After a short time,
the warning light stops flashing, but re‐
mains illuminated.
NOTE
The warning light flashes for about 6
seconds if the driver's seat belt is not fas
‐
tened when the ignition is switched ON.
To allow the passenger occupant classifi ‐
cation sensor to function properly, do not
place and sit on an additional seat cush ‐
ion on the passenger's seat. The sensor
may not function properly because the
additional seat cushion could cause sen ‐
sor interference.

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.

NOTE
To allow the passenger occupant
classification sensor to function
properly, do not place and sit on an
additional seat cushion on the
passenger's seat. The sensor may not
function properly because the additional
seat cushion could cause sensor
interference.
If a small child is seated on the
passenger's seat, the warning beep may
not operate.
Mexico
If the vehicle speed exceeds about 20
km/h (12 mph) with the driver or
passenger's seat belt unfastened, a warning
beep sounds continuously. If the seat belt
remains unfastened, the beep sound stops
once and then continues for about 90
seconds. The beep stops after the driver or
passenger's seat belt is fastened.
Until a seat belt is fastened or a given
period of time has elapsed, the beep sound
will not stop even if the vehicle speed falls
below 20 km/h (12 mph).
NOTE
Placing heavy items on the passenger's
seat may cause the passenger's seat belt
warning function to operate depending
on the weight of the item.
To allow the passenger seat weight
sensor to function properly, do not place
and sit on an additional seat cushion on
the passenger's seat. The sensor may not
function properly because the additional
seat cushion could cause sensor
interference.
If a small child is seated on the
passenger's seat, the warning beep may
not operate.
▼Retractable Hardtop Warning Beep*
When operating the retractable hardtop
switch, the warning beep is activated when
the retractable hardtop operation begins
and when it is completed.
If there is a problem with the retractable
hardtop, the warning beep is activated
continuously while operating the switch. If
the warning beep is activated continuously
while operating the switch, have the
vehicle inspected at an Authorized Mazda
Dealer.
▼Ignition Not Switched Off (STOP)

ignition switched to ACC, a beep will be
heard continuously in the cabin to notify
