To pull over and turn the car off to let it cool down.
Pull over when it is safe to do so then shut the engine off. If you continue to drive the vehicle catastrophic damage to the engine can occur.
engine coolant
no water
the three possible problems to this question are . your temperature sending unit is defective ,you could have problems in your wiring harness, or your temperature gauge is inoperative. I am a licensed mechanic and i have found your best place to start is to make sure you have input power to the sender and sensor and output to the gauge and or light in the system .If you have no output but you have input chances are your wirings fine and the sending unit or temperature sensors bad , you'll have to refer to the proper manual and check resistance.If you have output to the gauge and you have the proper voltage reference at the gauge ,chances are the gauge could be defective. The most common problem is a defective sensor though.

Over temperature warning.
Your check gauge light comes on if : your coolant temperature guage shows the temperature is high your oil pressure gauge shows the oil pressure is low or your fuel gauge shows the fuel tank is near empty
There is a battery light above the engine temperature gauge
There isn´t a one (W168). The car only has a temperature warning light.
try replacing the thermostat
The temperature gauge is broken.Could also be the temperature senor/sending unit, or a short in the circuit.
