Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Interior control
The temperature dial is used to set the nominal temperature. Turning upwards increases the nominal temperature; turning downwards lowers it. The useful temperature range is from 16 °C to 32 °C.
With a target value position of 32 °C [90 °F], the function MAX HEATING is activated. In the display, "HI" is displayed instead of the temperature value. The blower output is maximized. Interior control is thereby cancelled. The heat-exchanger temperature is regulated to the maximum temperature.
With a target value position of 16 °C [60 °F], the function MAX COOLING is activated. In the display, "LO" is displayed instead of the temperature value. The blower output is maximized. Interior control is thereby cancelled. The heat-exchanger temperature is reduced to the minimum temperature.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
