This light signals low oil pressure, which can cause engine damage from lack of lubrication or overheating. Stop the vehicle right away, check the oil level, and add oil if needed; do not drive until the issue is fixed to avoid major repairs.
Brake System Alert
It indicates problems like low brake fluid or a failure in the braking system, risking reduced stopping power. Pull over safely, inspect fluid levels if possible, and contact a mechanic immediately for inspection and repair.
Engine Coolant Temperature
This warns of high engine temperature, possibly from low coolant or a leak, which could lead to overheating and engine failure. Stop driving, let the engine cool, check coolant levels, and seek professional help before continuing.
Battery Charging System
It shows a fault in the battery or alternator, causing the vehicle to lose power soon. Stop as soon as safe, turn off non-essential electrics, and have the system checked by a service center to prevent stranding.
Airbag System
This light means a malfunction in the airbag setup, reducing protection in a crash. Stop and have it inspected at a dealer right away, as driving without functional airbags increases injury risk.
Seatbelt Reminder
It alerts if seatbelts are not fastened, reminding occupants for safety. Stop and ensure all passengers buckle up before proceeding, as unbelted travel heightens accident dangers.
Power Steering Failure
Indicates a problem with steering assistance, making the wheel hard to turn. Pull over immediately, restart the car to reset if possible, and visit a service center for repairs to restore safe handling.
Transmission Overheat
This signals high transmission temperature, often from heavy load or low fluid, risking gear damage. Stop the vehicle, allow it to cool, check fluid levels, and avoid driving until resolved.
Door Ajar
It warns that a door is not fully closed, which could open while driving. Stop safely, check and secure all doors, then resume travel to prevent hazards.
