Warning/Indicator Lights and Warning Sounds
If a Warning Light Turns On or Flashes
Brake System Warning Indication/Warning Light
This warning has the following functions:
Warning light inspection
For an operation check, make sure that the light turns on when the power switch is switched on and turns off a few seconds later, or when the EV system is started.
When the light turns on
If the brake system warning light remains illuminated the brake fluid may be low or there could be a problem with the brake system. Park the vehicle in a safe place immediately and contact an Authorized Mazda Dealer.
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:
Driving with the brake system warning light illuminated is dangerous. It indicates that your brakes may not work at all or that they could completely fail at any time. If this light remains illuminated, after checking that the parking brake is fully released, have the brakes inspected immediately.
-
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.
-
When starting the EV system, 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.
Electronic Brake Force Distribution System Warning
If the electronic brake force distribution control unit determines that some components are operating incorrectly, the control unit may illuminate the brake system warning light and the ABS warning light simultaneously. The problem is likely to be the electronic brake force distribution system.
Do not drive with both the brake system warning light and ABS warning light illuminated. Have the vehicle towed to an Authorized Mazda Dealer to have the brakes inspected as soon as possible:
Driving when the brake system warning light and ABS warning light are illuminated simultaneously is dangerous.
When both lights are illuminated, the rear wheels could lock more quickly in an emergency stop than under normal circumstances.
Output Restriction Warning Indication/Warning Light
“Acceleration Limited” displays/turns on
The indication/light displays/turns on under the following conditions. The vehicle speed may not increase even if the accelerator pedal is depressed because the motor output is restricted.
-
EV system is protected from overheating
-
High voltage battery level is low
-
High voltage battery temperature is low
“Acceleration Limited” displays/flashing
If the vehicle continues to be driven with the output restriction warning indication/warning light turned on, the output restriction warning light flashes.
The vehicle speed may not increase even if the accelerator pedal is depressed because the motor output is further restricted compared to the condition in which the output restriction warning light turns on.
“Excessive EV System Temp. Acceleration Limited Avoid Moving at Very Low Speeds. Depress Brake When Not Moving” or “Vehicle Cannot Hold Position. Depress Brake Pedal to Avoid Rolling” displays/turns on
When the vehicle is stopped on an upslope or the vehicle is driven at low speed on an upslope with the selector lever in the D or R position, the indication/light may display/turn on.
If necessary, park the vehicle in a safe place and let the EV system cool down because the output is restricted until the EV system returns to the normal temperature.
When the output restriction warning indication/warning light displays/turns on or flashes, check the safety of the surroundings:
The motor output decreases and the vehicle speed decreases resulting in an accident. If the vehicle cannot be driven safety, stop the vehicle in a safe place.
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.
TCS/DSC Indication/Indicator Light (Turns on)
If the light stays on, the TCS, DSC or the brake assist system may have a malfunction and they may not operate correctly. Take your vehicle to an Authorized Mazda Dealer.
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.
i-ACTIVSENSE Warning Indication/Warning Light (Some Models)
The indication displays if the system has a malfunction.
Check the reason for the indication displaying on the center display or multi-information display.
Refer to If a Warning Light Turns On or Flashes (Search).
Seat Belt Warning Indication/Warning Light (Front seat)
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 power switch switched ON.
If the driver or front passenger's seat belt is unfastened (only when the front passenger's seat is occupied) and if the vehicle is driven at about 20 km/h (12 mph) or faster, or about 10 km/h (6 mph) or faster for a continuous 30 seconds, with the seat belt unfastened, the warning light flashes for a certain period. After a short time, the warning light stops flashing, but remains illuminated.
-
The warning light flashes for about 6 seconds if the driver or front passenger's seat is not fastened when the power switch is switched ON.
-
Placing heavy items on the front passenger's seat may cause the front passenger's seat belt warning function to operate depending on the weight of the item.
-
To allow the front passenger occupant classification sensor to function properly, do not place and sit on an additional seat cushion on the front passenger's seat. The sensor may not function properly because the additional seat cushion could cause sensor interference.
-
If a small child is seated on the front passenger's seat, the warning light may not operate.
Action to be taken
Fasten the seat belts.
Seat Belt Warning Light (Rear seat) (Red)
If the rear seat belts are not fastened while the power switch is switched ON , the driver and the passenger are alerted by the warning light.
The warning light operates even if there is no passenger on the rear seat.
If a rear seat belt is not fastened by a certain period of time after the EV system has been started, the warning light turns off.
Action to be taken
Fasten the seat belts.
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.
