Refer to Inspecting Brake Fluid Level (Search).
Do not drive with the brake system warning light illuminated. Contact an Authorized Mazda Dealer to have the brakes inspected as soon as possible:

In addition, the effectiveness of the braking may diminish so you may need to depress the brake pedal more strongly than normal to stop the vehicle.
-
(With M Hybrid)
When starting the engine, the brake system warning light may turn on and the warning indication may be displayed. In this case, park the vehicle in a safe location and release the brake pedal.
If the brake system warning light/warning indication does not turn off even after parking the vehicle, have the vehicle inspected by an Authorized Mazda Dealer.
Charging System Warning Indication/Warning Light

If the warning light illuminates while driving, it indicates a malfunction of the alternator or of the charging system.
Drive to the side of the road and park off the right-of-way. Consult an Authorized Mazda Dealer.
Do not continue driving when the charging system warning light is illuminated because the engine could stop unexpectedly.
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.
-
When the engine is jump-started to charge the battery, uneven rpm occurs and the ABS warning light may illuminate. If this occurs, it is the result of the weak battery and does not indicate an ABS malfunction.
Recharge the battery.
-
The brake assist system does not operate while the ABS warning light is illuminated.

Security Indicator Light

If the security indicator light flashes continuously while you are driving, do not shut off the engine. Go to an Authorized Mazda Dealer and have it checked. If the engine is shut off while the indicator light is flashing, you will not be able to restart it.
Make sure the key is within the operational range for signal transmission. Switch the ignition off, and then restart the engine. If the engine does not start after 3 or more tries, contact an Authorized Mazda Dealer.

Low Washer Fluid Level Warning Indication/Warning Light (Some Models)

This warning light indicates that little washer fluid remains.
Action to be taken
Add washer fluid (Search).
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 ignition is switched OFF.
Action to be taken
