For the 2011 Toyota Highlander, it is recommended to use 0W-20 synthetic oil for the best performance and fuel efficiency. Always check the owner’s manual for the most accurate information.
To replace the cabin air filter, open the glove box and remove the dampener arm on the side. Squeeze the sides of the glove box to drop it down. Locate the cabin air filter cover, unclip it, and replace the old filter with a new one, ensuring the airflow direction is correct.
The towing capacity for the 2011 Toyota Highlander is up to 5,000 pounds when properly equipped with the towing package. Always consult your owner’s manual for specific towing instructions.
To check the transmission fluid level, ensure the vehicle is on a level surface, and the engine is warm. Locate the transmission dipstick, remove it, wipe it clean, reinsert it fully, and then remove it again to check the fluid level. The fluid should be between the "Full" and "Add" marks.
A squealing noise during startup can be caused by a worn or loose serpentine belt. Inspect the belt for signs of wear or damage and ensure it is properly tensioned. Replacing the belt may resolve the issue.
To replace a headlight bulb, open the hood and locate the back of the headlight assembly. Remove the power connector and the rubber dust cover. Release the retaining clip and remove the old bulb. Insert the new bulb without touching the glass, and reassemble.

To program a new key fob, insert the original key into the ignition and cycle it to "On" and back to "Off" five times. Remove the key, insert the new fob into the ignition, and turn it to "On". Wait for the security light to stop flashing. Test the new fob to ensure it is programmed.
If the check engine light comes on, ensure the gas cap is tight. If the light remains, use an OBD-II scanner to read the trouble codes or have a professional diagnose the issue. Addressing the issue promptly can prevent further damage.
