To reset the maintenance light on your 2012 Toyota 4Runner, turn the ignition key to the 'ON' position without starting the engine. Ensure the odometer reads 'ODO'. Turn the ignition off, then hold the trip meter reset button. Turn the ignition back to 'ON' while holding the button until the maintenance light turns off.
For a 2012 Toyota 4Runner, it is recommended to use SAE 0W-20 synthetic oil for optimal performance and fuel efficiency.
To replace the cabin air filter, open the glove box and remove the stop arm. Squeeze the sides of the glove box to release it fully. Behind it, you'll find the cabin air filter cover. Remove the cover, replace the old filter with a new one, ensuring the airflow direction is correct, and reassemble.
The 2012 Toyota 4Runner has a towing capacity of up to 5,000 pounds when properly equipped.
First, check the AC fuse and relay in the fuse box. Ensure the AC compressor clutch engages. Inspect for refrigerant leaks or low levels. If these steps do not resolve the issue, a professional diagnostic may be necessary.
The recommended tire pressure for the 2012 Toyota 4Runner is 32 psi for both the front and rear tires. Always check the owner’s manual or the tire placard for specific recommendations.
The 2012 Toyota 4Runner is equipped with a timing chain instead of a belt, which typically does not require regular replacement like a timing belt would.
To improve fuel efficiency, ensure regular maintenance such as timely oil changes, air filter replacements, and maintaining proper tire pressure. Additionally, avoid excessive idling and aggressive driving habits.
If the check engine light comes on, ensure the gas cap is tight, as a loose cap can trigger the light. If the light remains on, use an OBD-II scanner to read the error code or have a professional diagnose the issue.
To replace the spark plugs, disconnect the negative battery cable, remove the engine cover, and disconnect the ignition coil connectors. Remove the ignition coils and use a spark plug socket to remove the old plugs. Install new plugs, reattach the coils and connectors, and replace the engine cover.
