Toyota Corolla Dashboard Warning Lights Guide in Laurel, MD
At Sheehy Toyota of Laurel, one of the most common questions we receive from Toyota Corolla owners is about those mysterious dashboard warning lights. We understand that seeing an unfamiliar symbol illuminate on your dash can be concerning, so we've put together this guide to help you understand what your Corolla is trying to tell you as you drive around Laurel.
Check Engine Light
The check engine light is perhaps the most recognized warning indicator. When this amber engine-shaped symbol appears, it indicates that your vehicle's onboard diagnostic system has detected an issue with the emissions system or engine performance. This could range from a loose gas cap to a more serious problem with your catalytic converter or oxygen sensors. Don't panic if you see this light – bring your Corolla to our Service Department for a diagnostic scan, and we'll identify the exact issue and recommend the appropriate repair.
Oil Pressure Warning Light
This red oil can symbol is one you should never ignore. If it illuminates while driving, it means your engine oil pressure has dropped below safe levels. Pull over safely and turn off your engine immediately, then call for assistance. Continuing to drive with low oil pressure can cause severe engine damage. Our technicians can check your oil level, inspect for leaks, and ensure your oil pump is functioning correctly.
Brake System Warning Light
When you see the red "BRAKE" indicator or circle with an exclamation point, your Corolla is alerting you to a brake system issue. This could mean your parking brake is engaged, your brake fluid is low, or there's a problem with your brake system. If the light stays on after releasing your parking brake, schedule a service appointment right away. Your safety depends on properly functioning brakes, and our certified technicians can diagnose and repair any brake system concerns.
Tire Pressure Warning Light
The tire pressure monitoring system (TPMS) light looks like a horseshoe with an exclamation point. When it illuminates, at least one of your tires has pressure that's significantly below the recommended level. Underinflated tires affect handling, fuel economy, and can lead to tire failure as you head down Route 197. Stop by our Service Department for a complimentary tire pressure check – we'll inflate your tires to the proper PSI and inspect them for damage or leaks.
Battery/Charging System Light
If you see a battery symbol on your dashboard, it indicates a problem with your charging system. Despite what the symbol suggests, this doesn't necessarily mean your battery needs replacement – it could be your alternator, drive belt, or electrical connections. If this light appears while driving, try to make it to our Service Department before the battery drains completely. Our technicians will test your battery, alternator, and charging system to pinpoint the issue to fix it so you can get back to Laurel Park.
Maintenance Required Light
This orange wrench or "MAINT REQD" indicator is simply a reminder that your Corolla is due for scheduled maintenance, typically an oil change. It's programmed to illuminate based on mileage intervals. While not an emergency, keeping up with regular maintenance helps prevent more costly repairs down the road. Schedule your service appointment with us, and we'll reset this light after completing your maintenance.

“ Steve Horowitz in the new car sales department is a true class act and real professional all the way! My situation will speak to just how high his character and integrity really are. A few days ago I worked with Steve over the phone to locate a specific 2026 Grand Highlander in a certain color and interior that I had to have. Additionally, I needed a factory OEM tow hitch to be installed. Steve went above and beyond to contact the Toyota manufacturing facility in order to remove a number of pre-ordered options that I didn’t really care for, and furthermore to add the hitch that was essential to me. This took not only an extra step on his part, but also required numerous back and forth communication with him and I to see if it was even at all possible at this stage in production. In order to proceed a small $500 deposit was collected over the phone. The delivery of the vehicle was anticipated for early July. Yesterday morning I received a call from another dealer that I had spoken with late last week regarding the same car. Initially, that Highlander had already been reserved, however, I was notified yesterday that the transaction had fallen through. The difference here was that this dealer had the car on the lot and with everything I needed. Because of a situation that our family was in, with our Acura MDX having mechanical issues, we were planning on using my work sedan for a long family vacation next week. The reality of things was that this wasn’t ideal. As terrible as I felt knowing that I was potentially going to have to back out of the deal with Steve and now proceed with the new option—it just had to be done and was better suited for our family and trip. Last night we brought home that other car and this morning I noticed Steve of the news. I commend Steve for his understanding and professionalism upon learning of our change of plans. Without hesitation he agreed to not only refund the deposit, but genuinely understood our bit of a bind that we were in and held no hard feelings whatsoever. In fact, he fully supported and understood our situation and genuinely wished us well with our new vehicle. In a world where there’s an ever so challenging stigma of car salespeople being downright shady or completely self-serving, I felt the need to really tell Steve’s story here with the hopes that anyone shopping for a new Toyota should feel 100% comfortable knowing that working with Steve will result in the best car buying experience possible! When the time comes for me to replace my sedan, which honestly may be sooner rather than later, I know exactly who I’m calling first for that new or CPO Toyota Rav-4. ”
“ I had an excellent experience working with my car sales representative, Rico Leon. From the moment I walked in, they were knowledgeable, patient, and genuinely focused on helping me find the right vehicle—not just making a sale. They took the time to understand my needs, answered all my questions clearly, and made the entire process smooth and stress-free. I never felt pressured, which I really appreciated. I highly recommend them to anyone looking for a trustworthy and professional car buying experience ”
“ Darrell was great as always. Car ready early and all checked out. ”
“ Good place to go for regular maintenance and parts. Teresa went above and beyond. Even with some initial miscommunications, everything was wrapped up to my standards. ”
“ The person work which mi on servises on monday very good person i give to him five star at the place a d saler person and the department new car especific the man his name is jose i give to him one star an all de seller deparment one star ”
“ David is great always looking out for me and always keeping it real when it comes to the service I need !!! ”
“ Wait times could be a little better and that's only because the associates will let your car just sit after they've completed all the services and I will have to go to the counter to be checked out myself. The last service appointment i went to the counter myself because I saw that my car was sitting in the lot completed. The problem with that was that the young lady who assisted me was at lunch so the person who tried to help me couldn't locate my keys so I had to wait for the other young lady to come back from lunch. That should not be happening ”
“ Eyver Dominguez was very knowledgeable and helpful showing me the features on the RAV 4 plug-in hybrid. He’s an easy-going gentleman so I didn’t feel unduly pressured and yet a he’s an enthusiastic salesperson. ”
