2. Check that the idle speed corresponds to the nominal value (see section "Checking the idle speed").
3. Set the air conditioner switch to the "ON" position. Make sure that the idle speed corresponds to the nominal value with the air conditioner running and with different loads on the air conditioner.
Nominal value:
GDI engines:
- When working with low load - 700 + 50 rpm
- When working under high load - 850±50 rpm (800±50 rpm)*
- MPI engines - 800±100 rpm
Note:
- The symbol indicates that for the 4G93-GDI engine, after 4 minutes or more of engine operation at the base idle speed, the value of the increased idle speed will temporarily become equal to 800±50 rpm.
- - The value of the increased idle speed is set by the engine management system depending on the signal from the air conditioning electronic control unit.
- - High load on the air conditioner means that the following conditions are met:
- 1) The outside air temperature (at the evaporator inlet) is above 25°C, the "Ventilation" mode is on.
- 2) The air temperature at the outlet of the evaporator is above 15°C, the "Ventilation" mode is on.
- 3) The air temperature at the evaporator outlet is above 8°C, the "Recirculation" mode is on.
Low load on the air conditioner means that the conditions are different from those specified when the air conditioner is operating under high load.

4. If the increased idle speed value does not correspond to the nominal value, check the components of the fuel injection system (see the relevant chapter).
