Why It's Important to Reset the Acura TLX Maintenance Light
To ensure your Acura TLX remains in top condition, it’s vital to reset the maintenance light. This light helps track when oil changes are due and evaluates the oil condition in the engine, including the mileage until the next service. We also suggest keeping a personal record of each oil change and service by compiling all relevant service documents. Such a habit not only guarantees the best upkeep of your Acura TLX but also acts as evidence of regular maintenance, which is advantageous if you plan to sell the vehicle in the future.
Acura TLX Oil Type and Quantity
The 2015-2021 Acura TLX 2.4L 4 cylinder engine requires 4.4 Quarts of 0W-20 Synthetic oil. The 3.5L 6 cylinder engine requires 4.5 quarts of 0W-20 Synthetic oil.
How Often Should You Change the Oil on Your Acura TLX?
It’s recommended to perform an oil change on your Acura TLX every 3,000 miles. While some experts, service facilities, and dealerships may recommend longer periods between oil changes, sticking to a 3,000-mile interval is key. Consistently following this routine is important for preserving the engine’s performance in your Acura TLX and preventing a range of possible problems.
What to Do If the Acura TLX Service Reset Procedure Does Not Work?
If you encounter challenges while trying to reset the service interval on your Acura TLX, attempt the procedure once more. Shut off both the ignition and the engine, then begin the reset process again. Make certain that the hood and all doors are firmly shut before starting the procedure.
Why is the Acura TLX Maintenance Light Still On After An Oil Change?
After completing an oil change in your Acura TLX, it’s important to remember to reset the service intervals and maintenance alerts. Simply changing the oil and filter won’t turn off the maintenance light by itself. If the Acura’s maintenance reminder remains active post-oil change, it usually means that the reset step was overlooked by the individual who performed the oil change.
General Acura TLX Maintenance Tips
Check Tire Pressure and Tire Tread
To locate the recommended tire pressure for your Acura TLX, look for the white or yellow sticker on the door panel, which is visible upon opening the driver’s side door. Inflate the tires while they are cold to prevent overinflation. This involves either waiting for three hours after the car was last driven or inflating the tires prior to driving. For evaluating the tread wear on each tire, consider using the penny test or a tread depth gauge.
Rotate Your Tires
We recommend rotating the Acura TLX tires every other oil change, (if you are changing your oil at our recommended 3,000 mile interval) or every 6,000 miles.
Check the Coolant Level
Check the coolant level to ensure it is within the correct range in the coolant reservoir, specifically above the minimum and below the maximum line. Employing a flashlight can aid in better visibility inside the coolant container. Since the coolant system is a closed circuit, a significantly low coolant level could suggest a leak. Conduct a pressure test on the system to detect any possible leaks.
Check the Brake Pads and Rotors
Inspect the brake pad thickness for both the front and rear brakes of your Acura TLX to verify they have enough material. Utilize a brake pad gauge for an accurate thickness measurement. Additionally, assess the rotors for any indications of rust or abnormalities. When your Acura TLX is elevated on a jack or lift, rotate each wheel by hand (with the parking brake disengaged) to confirm they spin smoothly. Resistance in wheel rotation may point to issues with the brake caliper or seized slider pins in the caliper.
Check Brake Fluid Reservoir
It’s essential to maintain a full brake fluid reservoir. If the Acura TLX brake fluid level is significantly low, it usually indicates a leak in the system. Examine the brake calipers and lines for any evidence of leaks.
Check Washer Fluid Level
Refill your washer fluid reservoir. During winter, choose a washer fluid with antifreeze to stop it from freezing in the container.
Check the Engine and Cabin Air Filters
Open the air filter box of your Acura TLX and take out the air filter. If it looks dirty, clean it using a vacuum, compressed air, or by shaking out the dirt and debris. If the filter is overly dirty, replace it with a new one. If it’s still clean, just put it back in place. Also, don’t forget about the cabin air filter located behind the glove box, which purifies the air inside the car. Inspect this filter and replace it if it’s dirty or hasn’t been changed before.
Check the Acura TLX Power Steering Fluid
Make sure that the power steering fluid reservoir in your Acura TLX is topped up to the full line. If the fluid level is low, it could indicate a leak. In that case, top off the fluid and check the power steering lines for any leakage signs.
Benefits of Regular Oil Changes
Having worked as an automotive technician for over ten years in various dealerships and private workshops (I still am a tech), I’ve observed that cars skipping regular maintenance tend to encounter more frequent and serious problems. Despite some manufacturers suggesting oil change intervals ranging from 5,000 to 20,000 miles, my expert recommendation particularly for the Acura TLX, is to perform oil changes every 3,000 miles, irrespective of the guidelines set by Acura. This approach is crucial for preserving the vehicle’s optimal performance and longevity. Regular oil changes contribute to reducing engine wear and can improve fuel efficiency by as much as 2%. Additionally, it enables the engine to operate more cleanly, which is essential in preventing the build-up of harmful deposits that can diminish the engine’s lifespan.
