Toyota Tundra Dashboard Warning Lights Guide in Green Bay, WI
At our Le Mieux Toyota Service Department, we receive countless questions from Tundra owners about those mysterious dashboard lights. While your truck is equipped with advanced monitoring systems designed to keep you informed, we understand that seeing an unfamiliar warning light can be concerning. Let's walk through the most common dashboard indicators you might encounter in Green Bay, WI, and what they mean for your Tundra.
Check Engine Light
The check engine light is perhaps the most common warning we see. This amber engine-shaped icon can indicate anything from a loose gas cap to a more serious emissions or engine issue. When this light appears, your Tundra's onboard diagnostics system has detected a problem that needs attention. While it doesn't always mean you need to stop driving immediately, we recommend scheduling a diagnostic appointment with our service team as soon as possible. We'll connect your truck to our diagnostic equipment to read the specific trouble codes and determine the exact issue.
Brake System Warning Light
Your Tundra's brake warning light appears as a red circle with an exclamation point or the word "BRAKE." This indicator typically means your parking brake is engaged, your brake fluid is low, or there's a malfunction in the brake system. If this light comes on while driving down to Sherwood Forest Park with your parking brake released, pull over safely and check your brake fluid level. If it's low or the light remains on, contact our service department immediately, as brake system issues require urgent attention.
Tire Pressure Monitoring System (TPMS)
The TPMS light looks like a horseshoe with an exclamation point inside. When this illuminates, one or more of your tires has fallen below the recommended pressure. Temperature changes, especially during seasonal transitions, commonly trigger this warning. Schedule a service appointment for a complimentary tire pressure check and adjustment. We'll ensure all four tires are properly inflated according to Toyota's specifications. If the light blinks before staying solid, there may be a malfunction in the TPMS system itself that requires diagnosis.
Battery/Charging System Light
A battery-shaped icon on your dashboard indicates a charging system problem. This doesn't necessarily mean your battery is dead, but rather that your alternator isn't charging the battery properly, or there's an electrical system issue. If this light appears while driving, turn off unnecessary electrical accessories and head to our service center promptly. Continuing to drive with this warning could leave you stranded on Highway 141 with a dead battery.
Oil Pressure Warning Light
The oil can symbol is one warning you should never ignore. Low oil pressure can cause severe engine damage within minutes. If this red light appears, safely pull over immediately and turn off your engine. Check your oil level, and if it's low, add oil before continuing. However, even if the oil level appears normal, this light indicates a serious problem. Have your Tundra towed to our service center rather than risk engine damage by driving it.
Traction Control and 4WD Indicators
Your Tundra may display various lights related to traction control and four-wheel drive systems. A flashing traction control light means the system is actively working to prevent wheel slip. A solid light indicates the system is turned off or has detected a malfunction. Similarly, 4WD indicator lights show which mode your truck is in, and any unusual behavior warrants a visit to our service department.
When to Call Us
While some warning lights are informational, others demand immediate attention before you next head out to Christa McAuliffe Park. Our certified Toyota technicians have the specialized training and diagnostic equipment to accurately identify and resolve any issue your Tundra may be experiencing. Don't hesitate to call our Service Department during business hours if you're unsure about any dashboard warning light. We're here to keep your Tundra running safely and reliably for years to come.

Testimonials
“ The sales person Caleb A. was great to work with from start to finish! ”
“ The best ”
“ Great experience buying from Lemieux Toyota. This was the 4 vehicle we have purchased there. Our sales guy, Darek, is fantastic to work with (all 4 times). No pressure, no tactics, just a straight up good guy. If buying new, patience is needed to wait for the car to arrive, but that is to be expected for the best selling car on the market. We ordered and got exactly what we wanted! Will continue to be repeat customers. ”

“ People there are rude...absolute clown Show...Will never buy anything from there ever again ”
“ Most un knowledgeable parts staff I've ever worked with. It's sad. Couldn't even find a stock oem bolt replacement. I even took them to the truck and showed them directly. They told me i would have to contact the manufacturer of the skid plate for the hardware. I again told them it is an oem boIt and not aftermarket. If you really want to embarrass them i will stop back down and show someone more knowledgeable. Not only that, i will show them on every generation 3 tacoma you may have in yor lot. This is a stock item.Not even kidding here.Purchased 3 new vehicles here in the last 8 years. I expect better. Gave me the un easy feeling of low competency. It's like it's not even a Toyota dealership anymore. I am seriously asking myself why I spend my money here ”
“ Brought my 2025 GR Corolla in cause the clutch is slipping (still under warranty) and they straight up lied to my face and said nothing it wrong with it cause they don't wanna replace it under warranty. Derek Johnson was extremely rude and wouldn't talk to me, and another person in the service department wouldn't even give me their managers phone number. Extremely upset and never giving them a dime. Wouldn't let me give 0 stars but.. 0 stars. ”
“ U guys were terrible I will never come back again Don't bother me ”
“ My experience was with Don. And that was after expressing my alleged concerns to Toyota headquarters of North America. Which was my reason for taking the car that I purchased from Toyota for a roadside concern. ”
“ The quickest experience ever. Mason and the finance people we all amazing! ”
