To reset the tire pressure monitoring system, ensure that all tires are properly inflated. Turn the ignition to the "ON" position without starting the engine. Press and hold the TPMS reset button, located under the dashboard, until the TPMS indicator light blinks twice.
For optimal performance, use SAE 0W-20 oil with the API Certification Mark. This ensures proper lubrication and engine performance under various conditions.
To pair your smartphone, enable Bluetooth on your phone and in the Mazda Connect system. Go to the 'Communication' screen, select 'Bluetooth Settings', and then 'Pair New Device'. Your phone should detect the Mazda system, allowing you to pair the devices.
If the check engine light illuminates, first ensure the gas cap is secured, as a loose cap can trigger the light. If it remains on, consult a professional mechanic to diagnose potential issues with the vehicle's systems.
It is recommended to replace the air filter every 30,000 miles or as needed based on driving conditions. Inspect the filter regularly and replace it more frequently if you drive in dusty environments.
Locate the cabin air filter behind the glove box. Open the glove box and detach the dampener arm. Press in on the sides of the glove box to lower it fully. Remove the filter cover and replace the old filter with a new one, ensuring the airflow direction is correct.
The recommended tire pressure is typically 32 psi for both front and rear tires. Always check the sticker located on the driver's side door jamb for the most accurate information.
Brake inspections should be performed every 10,000 miles or at least once a year. Regular inspections help identify wear and potential issues that could affect braking performance.
To activate cruise control, press the 'ON' button on the steering wheel controls. Accelerate to your desired speed, then press the 'SET+' button to set the speed. Adjust speed with the 'RES+' or 'SET-' buttons as needed.
To replace a headlight bulb, turn off the engine and open the hood. Access the back of the headlight assembly, remove the electrical connector, and turn the old bulb counterclockwise to remove it. Insert the new bulb, secure it by turning clockwise, and reconnect the electrical connector.
