Warning/Indicator Lights and Warning Sounds
If a Warning Light Turns On or Flashes
If any warning light turns on/flashes, take appropriate action for each light. There is no problem if the light turns off, however if the light does not turn off or turns on/flashes again, consult an Authorized Mazda Dealer.
If the warning light/indicator light turns on or flashes, park the vehicle in a safe place immediately and take appropriate measures.
Continuing to drive the vehicle while ignoring the illumination/flashing of the warning light/indicator light is dangerous because a problem may occur to a vehicle system, or it could lead to an accident.
The details for some warnings can be viewed on the center display or multi-information display in the instrument cluster.

ABS Warning Indication/Warning Light

If the ABS warning light stays on while you're driving, the ABS control unit has detected a system malfunction. If this occurs, your brakes will function normally as if the vehicle had no ABS.
Should this happen, consult an Authorized Mazda Dealer as soon as possible.
The brake assist system does not operate while the ABS warning light is illuminated.
High Beam Control System (HBC) Warning Indication/Warning Light (Amber) (Some Models)

The light remains turned on if there is a problem with the system. Have your vehicle inspected at an Authorized Mazda Dealer.
Tire Pressure Monitoring System (TPMS) Warning Indication/Warning Light (Turns on)

If a tire pressure decreases below the specified air pressure, the TPMS warning light turns on.
At the same time, a message and the tire pressure of each tire are displayed on the multi-information display alternately. In addition, the tire (s) with low air pressure is displayed in yellow.

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.
While the TPMS is learning the tire positions, such as immediately after a tire position has been changed, the tire pressure at the tire position prior to it being changed is displayed until the system completes the learning. For this reason, the tire pressures displayed for the tire positions may be different from the actual tire pressures at the tire positions.
Action to be taken
Adjust the tire pressures to the appropriate pressures.
Refer to Tire Inflation Pressure (Search).
-
Adjust the tire pressures while the tires are cool. Because the air pressure in the tires fluctuates depending on the temperature, before adjusting the tire pressures, let the vehicle sit for an hour or drive it only within a 1.6 km (1 mile) distance. If the tire pressures are adjusted while the tires are warm, the tire pressures may decrease below the specified air pressure after cooling down which could turn on the warning light. In addition, because the air pressure in the tires decreases when the ambient temperature is low, if the ambient temperature increases, an illuminated TPMS warning light may turn off. Under any circumstances, always adjust the tire pressures while the tires are cool.
-
After adjusting the tire pressures, the TPMS warning light turns off. If the TPMS warning light does not turn off, drive the vehicle at a speed of about 25 km (16 mph) or faster for 3 minutes or longer and make sure the warning light turns off.
If the TPMS warning light remains on even after adjusting the tire pressures, one of the tires may have a puncture.
KEY Indicator Light (Green) (Flashing)

“Low Key Fob Battery. Replace Battery” is displayed/When the light is flashing
When the key battery is low, the indication is displayed when the power switch is switched OFF.
Action to be taken
Replace the key battery.

Under this condition, the keyless entry system will not operate, the vehicle cannot be locked, and the lead-acid battery voltage will be depleted.
Liftgate Door-lock Switch Inoperable Warning Beep (With the advanced keyless function)
When the door-lock switch on the liftgate is pressed under any of the following conditions, a warning sound is activated.
-
The power switch is switched to a position other than OFF.
-
Any door is open.
Make sure that none of the above conditions are present, and then press the door-lock switch again.
