To reset the "Maintenance Required" light, turn the ignition to the "ON" position without starting the engine. Press the "Trip" button repeatedly until the maintenance message appears. Then, press and hold the "Trip" button for about 10 seconds until the light resets.
The 2012 Nissan Altima typically requires SAE 5W-30 oil. Always refer to the owner's manual to confirm the recommended oil type and viscosity.
Rough idling can be caused by a dirty throttle body, clogged fuel injectors, or a faulty spark plug. Inspect these components and clean or replace them as necessary.
It is recommended to change the transmission fluid every 30,000 to 60,000 miles. Check the owner's manual for the specific maintenance schedule for your vehicle.
The recommended tire pressure for a 2012 Nissan Altima is typically 32 PSI for both front and rear tires. Verify with the tire information placard located on the driver's side door jamb.
To replace a headlight bulb, open the hood and locate the back of the headlight assembly. Twist and remove the bulb holder, replace the old bulb with a new one, and reinstall the holder. Be careful not to touch the glass part of the new bulb with your fingers.
Common reasons include low refrigerant levels, a faulty compressor, or a clogged condenser. Inspect these components and refill or repair as needed.
Enable Bluetooth on your smartphone. Press the "Phone" button on the Altima's audio system, then select "Connect" and "Add Phone." Follow the on-screen prompts and confirm the pairing code on both the car system and your phone.
First, ensure the gas cap is properly tightened, as a loose cap can trigger the light. If the light remains on, use an OBD-II scanner to check for diagnostic trouble codes and address the underlying issue based on the codes.
Symptoms may include dimming headlights, a dead battery, unusual noises, or electrical issues. If you experience these issues, test the alternator's output and replace it if necessary.
