You can disconnect the negative cable of the battery for a couple of minutes (but you will lose radio settings and possibly others that the car will relearn), or you can go to an auto parts store such as Advance Auto or Pep Boys and they have a free scanner service to diagnose problems that should be able to reset the light. Mine does.

Sir
when the fuel nozzles are partly blocked this type of defects are experienced. Try "wurth nozzle cleaner" and see.

Most Suzukis A/C systems will cut out when the engine tempurature is too high (to reduce the load on the engine). Also, in this condition, when the A/C compressor cuts out, the A/C thermo fan (electric - in front of the condensor) may come on ( to try and cool the engine). Combined with the fact that your temp gage says the engine is hot, I would be checking your cooling system very closely. It could be as simple as leaves blocking the air flow through the radiator (between the condensor and radiator), or as serious as the internal cores of the radiator being blocked (different sorts of coolant being used can sometimes produce solid matter that can do this).

Testimonial: "Great explanation and advice to check the cooling system, specifically the radiator. Unfortunately the internal core of the radiator was blocked."
