Tire Pressure Monitoring System - Mazda 3 2018 Smart Start Manual

TIRE PRESSUR E MONITORI NG SYSTEM
TIRE PRESSURE MONITORING SYSTEM (TPMS)
For your safety, the Mazda3 is equipped with TPMS that detects low
tire pressure in one or more tires. If the tire pressure starts getting
low in one or more tires, the system alerts the driver by turning on
a light in the instrument cluster (p. 44) and sounding an alarm.
WHAT TO DO? Don't ignore the TPMS warning light. Stop and check
your tire pressure (when tires are cold) and inflate them to the proper
pressure. Properly inflated tires are safer, last longer, and increase
fuel economy.
In the following cases, the TPMS must be "initialized" so the
system can operate normally.
• The tire pressure is adjusted (up or down) in one or more tires.
• A tire rotation is performed.
• Any tire or wheel is replaced.
• The vehicle's battery is disconnected, replaced or completely dead.
INITIALIZATION PROCESS (TPMS WARNING LIGHT
1 Park the vehicle in a safe place and firmly apply the parking brake.
2 Let the tires cool, then adjust the tire pressure to the
specified pressure (see the tire label located on the driver's
side door opening) on all four tires.
3 Switch the ignition ON, but leave the vehicle parked.
4 Push and hold the TPMS "Set Switch" (left side of dash) until
the TPMS warning light
twice and a beep sound is heard once.
NOTE:
Drastic changes in temperature or altitude can affect the air pressure in the tires,
and may cause the TPMS warning light to turn on. Verify the tire pressures when driving
through extreme temperature or altitude changes.

CAUTION:
If the TPMS "Set
Switch" is pushed
without adjusting
the tire pressure,
the system cannot
detect the normal
tire pressure. The
TPMS warning
light may not turn
on, even if the tire
pressure is low, or it
may turn on if the
tire pressure
is normal.
