Learn the warning symbols show up on your dashboard

Coolant Warning Light

Without any coolant, your car’s engine might get overheat and resulted in reduced engine performance. If you see the coolant light showing up on your dashboard, it is possible the coolant level is running low, so check the gauge on the side of the coolant tank under the bonnet and fill up if necessary. Sometimes it may indicate sign of other problems, like a head gasket failure or a leak in the system to cause overheat problem, and a sign to have your vehicle to be inspected and repaired by authorized Mazda Repairer.

Brake System Warning Light

The light illuminates when the parking brake is applied with the ignition switched to START or ON. It turns off when the parking brake is fully released.

If the brake warning light remains illuminated even though the parking brake is released, the brake fluid may be low or there could be a problem with the brake system. You may notice that the pedal is harder to depress or that it may go closer to the floor. In either case, it will take longer to stop the vehicle. Even if the light turns off, have your brake system inspected as soon as possible.

Battery Charge Warning Light

The battery charge warning light normally appears for a few second when you turn your car on, but if it keeps on after the engine starts, there could be a problem with the electrical system of the car. This could be to do with a faulty alternator, faulty battery, a bad connection or damaged cabling somewhere in the engine bay. If the car is not charging its battery properly when running, then the battery could be eventually running out of electrical power and be grind to a halt.

The warning light could also be on due to an alternator drive belt breaking whereas other systems also use this belt, such as the engine coolant pump, or power steering. Having come across this compounded failure, the repair will become sophisticated. The vehicle should be back to authorized service centre for detail inspection.

Tyre Pressure Monitor Warning Light

Tyre Pressure Monitor System (TPMS) monitors the air pressure of all four wheels. If the air pressure of one or more tyres is low, the system warns drivers by indicating the tyre pressure monitoring system warning light in the instrument cluster and operating a beep sound. The system monitors the tyre pressures indirectly using the data sent from the ABS wheel speed sensors.

To allow the system to operate correctly, the system needs to be initialized with specific tyre pressure (value on the tyre pressure label). In the following cases, system initialization must be performed:

  • A tyre pressure is adjusted
  • A tyre or wheel is replaced; tyre rotation is performed
  • The battery is replaced
  • The tyre pressure monitoring system warning light is illuminated.

To Initialize the system, first park properly; Let the tyre cool and adjust tyre pressure of all wheel; Switch the ignition ON; Lastly press and hold the Tyre Pressure Monitoring System "SET" switch.
