The Stability Control Light indicates that the vehicle’s electronic stability control system is operational, enhancing traction and control. If this light is active, it suggests that the system is working to enhance traction. The traction control system helps maintain vehicle stability by applying brakes to slipping wheels.
If the stability control light remains on or flashes, it is advisable to have the vehicle inspected to ensure the system is functioning correctly. Promptly addressing this light helps maintain vehicle stability and prevents potential accidents.
Engine and temperature warning lights are critical indicators of your vehicle’s health. These lights alert you to issues such as overheating, low oil pressure, and transmission problems. Addressing these lights promptly can prevent severe engine damage and ensure your vehicle operates efficiently. The engine warning light is particularly important to monitor.
The transmission temperature warning light indicates a critical internal gearbox temperature. Heavy towing, low transmission fluid, or excessive wear can cause this light to activate, signaling that immediate attention is needed.
The Engine Temperature Warning Light indicates that the overheating engine is overheating. This warning light is triggered when the engine coolant temperature is not normal, signaling overheating. Causes of overheating can include a broken water pump, low coolant levels, leaking hoses, or a damaged radiator.
When this light is illuminated, it is advisable to turn off the air conditioning, turn on the heater, and pull over to let the engine cool. After topping up coolant, if the engine temperature warning light stays on, it’s important to have the vehicle checked to identify and fix the underlying problem. Ignoring this warning can lead to serious engine problems.
The Oil Pressure Warning Light indicates low oil pressure in the vehicle. An illuminated oil pressure warning light may indicate low oil level, an oil leak, obvious oil leaks, or worn parts like the piston ring or oil pump.
