A circle with question mark symbol on the outside

The list of symbols are in your owners manual.
Usually the mark is surrounded by another symbol such as a circle for tire which involves the brake system, or a triangle which could be a list of different things affecting safety.

I guess you have no owners manual !!

Tire Pressure Monitor Symbol

Go to a tire store-- they will explain it to you
& resolve any issues there

Hi,
What Year/Make/Model of vehicle? The symbols are described in the owner's manual, too.

Td

this light for coolant level indicator top up coolant level then s.w off and on , check for coolant leakage may be leakage from radiator sender.

Should consult manual but usually this symbol means either tire pressure or could be brake pad wear if it has a circle with another circle around it such as -- (O)
Sometimes this could also mean your ebrake is engaged. Even if it is not engaged the sensor could be bad.

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 circle with an exclamation mark is usually the low tire indicator (that symbol is a tire and a tire gauge). sometimes when the temperature drops down, one of the tires will show up as low & later in the trip when the tire warms up, it will read correctly. Or, you can just have oone that is too low & need air. good luck

Brake pads
●
Have the brake pads checked
immediately.
For your own safety: use only
brake pads that BMW has
released for your particular vehicle
model. BMW cannot evaluate nonapproved
brake pads to determine if
they are suitable for use, and therefore
cannot ensure the operating safety of
the vehicle if they are installed.<

Check ther coolant level, if this is ok, its possible the sensor on the coolant resevoir faulty. the other warning light sounds like the brake pad warning light. is the warning yellow?
