I'm getting a symbol on the dashboard, it looks like a half circle with an exclamation mark in the middle. I lost the manual so I do not know what this means, can you help?

Looks like a brake related warning like brake fluid or parking brake.

Its probably a brake warning light. The symbol would be an exclamation mark between two half circles which resemble brake shoes.
Check your owners manual for details.

Its a warning to check brakes,pads have sensors to warn you early
Get all pads checked
Look in owners manual so you know what all warning lights are

Check your tire pressure. One of your tires has lost enough tire pressure to trigger this alarm. It could also be a puncture by nail or something. Once you've checked your tire pressures and set them all to desired pressure (30psi - depending on tire model and passenger occupancy) you can reset this alarm by pressing and holding down the button (apprx. 10 sec) located on the front of base of the emergency brake (same symbol on button as alarm). Blinking yellow light will stop blinking and stay on (this is when you can stop pressing the button), but eventually, shortly dissappear. I think the alarm is triggered by a difference of 4-6 psi which can aso be affected by climate change (warmer to colder season or visa versa).

There are two symbols with an exclamation mark. The first is a oblong circle with the exclamation mark inside with ( ) on each side of the oblong circle. That symbol is for brake system warning light. Check brake fluid level, check brake pads. The other symbol is (!) and is flat on the bottom its suppose to resemble a tire, it means there is a problem with the tire monitor system, check your tire pressure, if you have low tires you will have to drive car after servicing the tires then the light should go out. Tire pressure should be on a placard on the driver door or door frame.

A yellow explanation point symbol on the dashboard typically applies to the Tire Pressure Monitoring system. A thick ! inside a half drawn flat tire symbol to be complete and comes in yellow color when lit. Under normal vehicle set-up, if this indicator stays lit after the power-on selftest, you need to check your tires for any uneven pressures and adjust their pressures to correct specifications. Okay? : )

A red exclamation point inside a circle when lit indicates your parking brake is on, or your brake fluid level is low.

If you mean a circle that looks sort of like a gear with an exclamation mark in the middle, it represents the Transaxle fault light.

That should be your handbrake light

I already found the owner manual on the internet. thanks for helping me out.

press your parking brake lever all the way down then check your brake fluid level. if its low, then add.
