To replace the cabin air filter, open the glove box, disconnect the dampener, and remove the glove box. The filter is located behind a cover on the passenger side. Remove the old filter and insert a new one.
A rattling noise could be due to loose components, exhaust system issues, or engine problems. It is recommended to have a professional mechanic diagnose the issue to avoid further damage.
To improve fuel efficiency, ensure regular maintenance, keep tires properly inflated, avoid excessive idling, and drive smoothly without rapid acceleration or braking.
If the check engine light comes on, check for any loose gas caps first. If the light remains on, have the vehicle diagnosed by a professional to identify the issue.

To check the transmission fluid, warm up the car, park it on a level surface, and keep the engine running. Locate the transmission dipstick, remove it, wipe it clean, reinsert it, and then check the fluid level.
