That means that there is an issue has been detected by the engine management system and needs to be addressed. If there is an Auto Zone or a large Auto parts store, they can scan the car for the DTC codes so you can address the issue. Auto Zone scan free of charge and can give you the recommendation to addressing the issue and should have the part needed, and the step by step instructions for you to get the job done with common tools. Good luck and keep me posted, it could be as simple as a bad gas cap.

If the check engine light is on. It means that there was a problem detected by your car's computer. If your car is still running with the light on, it may not be a serious issue. Try first disconnecting the battery for 2 minutes. If that does not remove the light you will have to have a scanner to get the exact error code to diagnose the problem accurately.

Battery and brake light on


For some reason the brake warning light and battery light are connected, so either system could be having problems.
The battery warning light could mean the battery is not being charged, and the brake warning light could mean you are low on brake fluid.
I would start with the check engine light and see what the codes are.

An orange warning light shaped like an engine has come on what does it mean


Engine warning light

eng_man_light_72.jpg 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
