This past month a warning light in my car keep on flashing on my dashboard i tried to check it on the car's manual but i did not give me a specific meaning for it. Thats why im posting this.
Warning Lights
What does that light on the dashboard mean?
As cars have become more and more sophisticated the number of possible faults that can arise has grown significantly, along with the number of different warning lights that might flash up on the dashboard. Some of the more common warning lights are shown below together with advice on what to do if they're displayed on your car.
A 2006 survey by AA Personal Loans found that almost half of women (47 percent) and one third of men (33 percent) couldn't correctly identify symbols for frequently used functions or basic warning lights.
Many warning lights are specific to the manufacturer or even the model but you should find a detailed explanation of their meaning in the vehicle handbook.
If a warning light appears (or fails to extinguish after you've started the engine) you should stop as soon as possible in a safe place and refer to the handbook in the first instance. Besides describing the fault the handbook should also indicate whether it's safe to continue driving or not.
Oil pressure warning light
This light should illuminate when the ignition is switched on and should extinguish as soon as the engine starts.
If the light stays on after starting or illuminates during a journey, stop immediately, switch off the engine and check the engine oil level.
Top up straight away if the level is low.
If the warning lamp illuminates, even though the oil level is correct, do not start the engine and seek assistance.
Battery charge warning light
This light should illuminate when the ignition is switched on and should extinguish as soon as the engine starts.
If it does not illuminate at all, or if it illuminates while driving, your battery is not being charged as there is a fault with your charging system.
This may be due to one of the following;
- slack battery or starter terminals
- a broken or loose alternator drive belt
- an alternator failure
If the drive belt is broken, it must be replaced before you restart the engine. The coolant system may rely on this belt and its failure could cause the engine to overheat, in turn causing engine damage.
Immediately move the vehicle to a safe location and switch off the engine. Do not restart the engine and seek assistance.
Brake system warning light
This light will remain illuminated when the handbrake is engaged. Illumination after releasing the handbrake may indicate low brake fluid level.
Refer the the handbook and add the correct brake fluid at once to bring the level up to the MAX mark. As the brakes wear the fluid level will slowly drop. Check your brake fluid level frequently to ensure there is no further rapid loss of fluid.
If the brake fluid is too low and brake pedal travel is distinctly longer than usual, one of the two hydraulic brake circuits may have failed. Do not continue your journey and seek assistance.
If the light remains illuminated, even though the brake fluid level is correct, this may indicate a sensor fault. Take your vehicle to a dealer or garage as soon as possible.
Engine warning light
Illuminates when the ignition is switched on. It should extinguish as soon as the engine starts.
If it illuminates with the engine running, it indicates a malfunction with the engine management system. Have this checked as soon as possible.
If it flashes when driving, reduce the vehicle speed immediately until the light illuminates constantly. If it continues to flash, avoid heavy acceleration and high engine speed, stop the vehicle and have it checked immediately.
On some vehicles this light may be red - again stop the vehicle and seek assistance.
If it is safe to do so, try stopping the vehicle, switching off the engine, wait two minutes, then restarting the engine to reset the engine management system.
With the light illuminated, the vehicle is still safe to drive as long as no other faults are apparent with the engine. Have the vehicle checked by a dealer or garage as soon as possible to avoid any damage being caused to the catalytic converter.
ABS warning light
When the ignition is switched on, the light illuminates briefly to confirm that the system is operational.
If it illuminates when driving, it indicates a malfunction. Have this checked as soon as possible.
Normal braking (without ABS) will be maintained.
The vehicle is still safe to drive, but you should have the vehicle checked by a dealer or garage as soon as possible.
Brake system and ABS warning lights
If both warning lights illuminate at the same time when driving, stop the vehicle as soon as it is safe to do so.
Reduce vehicle speed gradually and immediately move the vehicle to a safe location. Use the brakes with great care. Do not step on the brake pedal abruptly. Seek assistance.
Fuel filter water trap (diesel engines)
This light illuminates when the ignition is switched on and should extinguish after a few seconds.
If it illuminates while driving, it indicates that water has been detected in the fuel filter.
This light warns you that the amount of accumulated water in the fuel filter has reached the specified level.
Normally the vehicle is quite safe to drive, but have the accumulated water in the fuel filter drained off as soon as possible.
If the vehicle has just been re-fuelled, immediately move the vehicle to a safe location and switch off the engine. The fuel may have been contaminated and could cause damage to the injection system.
