Brake and battery warning lights on a KIA sorento 2003 diesel, what means this alerts in combination . We added brake fluid, ald all lights turned off, but I suspect also on the belt tension, could it this be related events.

None of those would be fixed by replacing the battery. Or did you replace the battery and then all of those stopped working?

You can tell of blade fuses are blown if you full them and hold them up to the light. That is a whole lot of stuff not working. I would say you need a good auto-electrician.

Maybe a low battery

Question: does the sign IMMO (yellow) light disappear after some seconds of ignition turned on? If not you may have to close your car with your keys, than open them with the keys, than start your engine.
Should work if you are experiencing the above problem... Just an idea.

Kia Sorento parking brake or brake fluid dash warning light - this light is illuminated when the park brake is applied, the warning light should go out when the parking brake is released. If the light does not go out it indicates that the brake fluid level in the reservoir is low and you need to pull over and top up at your first opportunity.

1-check parking brakes not applied
2-check brake fluid
3-if it is too low have the brakes checked they might be wearing out it doesn't mean you have a leak but when the brakes wear out the become thin causing the caliber piston to push out more lowering the oil level in the reservoir

The code is not complete it should be P0571
P0571 KIA - Brake Switch A Circuit
Symptoms - Engine Light ON (or Service Engine Soon Warning Light)
- Stop light inoperative
- Cruise control system inoperative Possible causes - Misadjusted brake switch
- Brake switch open or short circuit
- Poor brake switch electrical connection
- Failed brake switch

if it is a four wheel drive vehicle it may mean that four wheel drive is engaged.....cheers.

Just tow choice in your 2003 Kia Truck Sorento 3.5L SFI DOHC 6cyl:
- Your Ignition Switch is damaged; or,
- Your wires for the Warning Buzzer Relay is damaged.

Even when the OFF position any connection is open and drain your battery.

Check it and tell us news.

if this is a standard it"s time for a clutch and preasure plate.

you might not have replaced the gas cap correctly or the cap gasket is deteriorated

2. Sound like your alternator is not putting enough amp out at idle. Have someone check your alternator out.
