To reset the maintenance light, turn the ignition key to the "On" position without starting the engine. Press and hold the trip meter reset button, then turn the ignition key to the "Off" position. Continue holding the button and turn the ignition back to "On." The maintenance light should flash and then go out.
The recommended oil type for a 2012 Toyota Tundra is SAE 0W-20. This oil provides optimal fuel efficiency and performance.
Open the glove box and remove the damper by sliding it off. Press in on the sides of the glove box to release it from the dashboard. Behind the glove box, locate the cabin air filter cover, remove it, and replace the old filter with a new one.
Common causes include a loose gas cap, a faulty oxygen sensor, a malfunctioning catalytic converter, or issues with the mass airflow sensor. A diagnostic scan can help determine the exact issue.
To change the spark plugs, disconnect the battery, remove the engine cover, and locate the ignition coils. Remove the coils and use a spark plug socket to remove the old plugs. Install the new plugs, reattach the coils, and replace the engine cover.
It is recommended to rotate the tires every 5,000 to 7,500 miles to ensure even tire wear and extend their lifespan.
The AC may not blow cold air due to low refrigerant levels, a clogged cabin air filter, or a malfunctioning compressor. Checking and refilling the refrigerant or inspecting the AC system may be necessary.
To check the transmission fluid level, warm up the engine and park on a level surface. Locate the transmission dipstick, remove it, wipe it clean, and reinsert it. Pull it out again and check the fluid level, which should be between the "Full" and "Low" marks.
The towing capacity of a 2012 Toyota Tundra varies based on the configuration, but it generally ranges from 4,500 to 10,400 pounds. Verify your specific trim and package for precise capabilities.
To replace a headlight bulb, open the hood and locate the back of the headlight assembly. Disconnect the power connector, remove the rubber boot, and unclip the bulb. Insert the new bulb, reattach the clip, boot, and power connector.
