Light Mexico
The seat belt warning light turns on if the
driver or front passenger's seat is occupied
and the seat belt is not fastened with the ig-
nition switched ON.
If the driver or front passenger's seat belt is
unfastened (only when the front passenger's

seat belt warning function to operate de-
pending on the weight of the item.
•To allow the front passenger seat weight
sensor to function properly, do not place
and sit on an additio
nal seat cushion on
the front passenger's seat. The sensor may
not function properly because the addi-
tional seat cushion could cause sensor in-
terference.

Tire Pressure Monitoring Syste
m Warning Light (Turns on)
*
Take the appropriate action and verify that the warning light t urns off.
Wa r n i n g
When the warning light illuminates, and the warning beep sound is heard when 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 maneuvering 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 sudden maneuvering or braking. Vehicle
drivability could worsen an d 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 da ngerous, 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 accident.

Action to be taken
Inspect the tires and adjust to the specified inflation pressur e (page 6-41).
CAUTION
When replacing/repairing the tires or wheels or both, have the work done by an Authorized Mazda Dealer, or the
tire pressure sens ors may be damaged.
NOTE
•Perform tire pressure adjustment when the tires are cold. Tire pressure will vary according to the tire tempera-
ture, 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 warning 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 illuminated, drive the vehicle at a speed of at least 25 km/h (16 mph) for 10 mi-
nutes, and then verify that it turns off.
•Tires lose air naturally over time an d the TPMS cannot tell if the tires ar e getting too soft over time or you
have a flat. However, when you find one low tire in a set of four-tha t is an indication of trouble; you should
have someone drive the vehicle slowly forward so you ca n inspect any low tire for cuts and any metal objects
sticking through tread or sidewall. Put a few drops of wa ter 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 th e 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.
