SOURCE: engine lights come on with an arrow pointing down
is it an engine light or is a flat/low tire pressure light?If you TPM ( tire pressure Monitor) on vehicle each sensor lets you know that tire pressure is low, if pressures are good( check when cool, yes cold tire pressure) the batteries in each sensor could need replacing, l could be out to left field but an engine light with arrow pointing down doesn't seem right.Good Luck

It means reduced engine power. Check for vaccum leaks and at the very least, clean your throttle body. Reduced engine power is like a safe mode, needs to be check out right away.

If the ! symbol you saw is inside a circle enclosed in parentheses like (O), and usually red in color, that's for your brake fluid. Check it out, maybe its low on fluid. If it is, check for fluid leaks or worn brakepads. Usually the ! symbol coincides with the P symbol and also red in color. When the park brake is engaged, both these symbols appear together. If you release the park brake, both indicators should turn off under normal conditions, otherwise either of the two or both will stay on when there is insufficient fluid or there's a parking brake circuit fault. Brakes are very important, so give proper attention and solution if ever these indicators lightb up when they shoud not.
If the ! symbol is very bold and inside a half drawn flat tire, and yellow in color, thats the tire pressure monitor indicator. Check and balance all four tire pressures to the correct specification.
Okay, sir? have a safe trip. : )
