🔍 Every Acura TL Dashboard Symbol — Full Details
Below is the most comprehensive list of Acura TL warning lights, including less common indicators like VSA, AFS, steering lock, maintenance minder, and washer fluid. Each card explains the definition, common causes, urgency, and recommended action.
Why: Misfire, O2 sensor, catalyst, EVAP, loose gas cap. Flashing = severe. Action: Scan codes; if flashing stop engine. Safety: Solid: limited driving; flashing: unsafe.
Why: Low oil level, pump failure, clogged filter. Action: Pull over, shut off, check oil. Safety: Never drive — engine destruction.
Why: Alternator not charging, bad belt, corroded terminals. Action: Check connections, drive to shop; may stall. Safety: Limited range, power steering loss.
Why: Park brake on, low fluid, hydraulic failure. Action: Release brake, check fluid; if stays, do not drive. Safety: Extremely dangerous — call tow.
Why: Wheel speed sensor, pump, control module. Normal braking works. Action: Diagnostics; possible sensor cleaning. Safety: Safe, but no ABS on slippery roads.
Why: Low tire pressure, sensor battery dead. Action: Inflate to spec; if flashing, sensor fault. Safety: Safe but adjust soon.
Why: System off, fault in yaw sensor, steering angle. Action: Try pressing VSA button; if stays, scan. Safety: Safe but stability reduced.
Why: Headlight leveling malfunction, sensor or motor. Action: Check if headlights work manually; dealer repair. Safety: Safe but cornering lights may not swivel.
Why: Fault in airbag system, clock spring, crash sensor. Action: Immediate dealer inspection. Safety: Airbag may not deploy — high risk.
Why: Overheating (red) or cold (blue). Red = stop engine. Action: Check coolant, fans, radiator. Safety: Red = unsafe, engine damage.
Why: Oil life low (15% or 0%), service due. Action: Schedule oil change, reset after service. Safety: Safe, but don’t ignore long term.
Why: Fuel level low. Action: Refuel soon. Safety: Safe, but risk of running out.
Why: Low windshield washer fluid. Action: Top up reservoir. Safety: Safe, but reduced visibility if dirty.
Why: Door, hood or trunk not fully closed. Action: Check all panels. Safety: Safe only if closed properly.
Why: Steering column lock malfunction, electric power steering fault. Action: Try restart, if persists dealer. Safety: May affect steering, avoid driving.

🛠️ How to Diagnose & Reset Warning Lights
Step 1: Note color and symbol. Step 2: Check owner’s manual. Step 3: For amber lights, use an OBD2 scanner (engine, ABS, SRS may need advanced scan). Step 4: For red lights, stop engine immediately. Resetting: Some lights reset after fixing (TPMS after inflation). Maintenance minder reset: with ignition ON, press SEL/RESET until oil life flashes, then hold again. Check engine lights usually require scan tool clear or several drive cycles after repair.
