Warning/Indicator Lights and Warning Sounds
Air Bag/Seat Belt Pretensioner System Warning Indication/Warning Light

A system malfunction is indicated if the warning light constantly flashes, constantly turns on or does not turn on at all when the power switch is switched ON. If any of these conditions occurs, consult an Authorized Mazda Dealer as soon as possible. The system may not operate in an accident.
Never tamper with the air bag/pretensioner systems and always have an Authorized Mazda Dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pretensioner could accidentally activate or become disabled causing serious injury or death.
Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Flashing)

If there is a problem with the TPMS or the voltage of a tire pressure sensor decreases, the TPMS warning light flashes and a message is displayed on the multi-information display. Have your vehicle inspected by an Authorized Mazda Dealer.
Do not drive the vehicle at high speeds if the TPMS warning light turns on or flashes:
Driving the vehicle at high speeds while the TPMS warning light is turned on or flashing is dangerous because the brake performance and the steering wheel operability will be reduced. If the vehicle is driven at high speeds or the brakes are suddenly applied, it could lead to an accident. Gradually apply the brakes to lower the vehicle's speed.
Do not ignore the TPMS warning light when it is turned on or flashing:
Continuing to drive the vehicle while ignoring the illumination/flashing of the TPMS warning light is dangerous because a tire may burst which could lead to an accident. Take appropriate measures as soon as possible.
Security Indicator Light

If the security indicator light turns on/flashes while driving, do not stop the EV system (leave it operating) and have the vehicle inspected at an Authorized Mazda Dealer. If the EV system is stopped, it may not be restarted.
If the EV system cannot be started, switch the power switch OFF, place the key in another position within the operation range, and then restart the EV system.
Check the security indicator light and if it does not turn off, such as it remains on or flashes, switch the power switch OFF, wait for a while, and then restart the system.
If the EV system does not start after three attempts, a system malfunction may have occurred. Have the vehicle inspected by an Authorized Mazda Dealer.
Because the electronic codes are reset when the immobilizer system is repaired, the keys are needed. Make sure to bring all the keys to an Authorized Mazda Dealer so that they can be programmed.
