Removing and installing heating and fresh-air control: Installation
- Ensure that the air distributor casing and air guides are correctly positioned. Engage the electrical plug connections and carefully lay the electrical cables (do not pinch).
- Comply with safety regulations when handling airbag units (see SAFETY REGULATIONS FOR VEHICLES WITH AIRBAG AND BELT TENSIONER
).
- Set the steering column switch: Measure with a depth gauge between end of steering shaft and steering-column switch cover plate (see Fig 1
). Adjustment dimension 55 +/- 0.5 mm.

- Replace gasket between current distributor and firewall if necessary. After the current distributor is mounted on the firewall (tightening torque 15 Nm (11 ftlb.)) the battery cable is tightened with a new hexagon nut M8. Tightening torque: 15 Nm (11 ftlb.)
- The heat exchanger is connected to the engine cooling system, and coolant flows through it when the engine is running. After removing or installing the heating/fresh-air control, vent the cooling system (see DRAINING AND FILLING IN COOLANT (INCLUDES: BLEEDING)
).
