The supplementary heater comple-ments engine coolant heating imme-diately after start up and when trav-elling to reach the optional engine op-eration temperature and to heat thepassenger compartment faster.The electrical device is fully auto-matic and will only work when theengine is running.IMPORTANT The supplementaryheater will be switched on when theoutside temperature is lower than15°C and the engine coolant temper-ature is lower than 65°C.To prevent excessive intake of bat-tery current, the heater operation atthe various power percentages is sub-jected to the power voltage measuredby the control unit.IMPORTANT The operation of theheater according to engine coolanttemperature consequently can be cutout or reduced according to the bat-tery voltage.At the end of the operation cycle de-veloped according to the temperatureof the engine coolant and the batteryvoltage, the supplementary heater isautomatically switched off. It will notcome on again until the following en-gine start-up, even if the coolant tem-perature drops to under 65°C.115STEERINGCOLUMN STALKSLEFT-HAND STALKThis stalk groups the outside lightand the direction indicator controls.The outside lights will only light upwhen the ignition key is at MAR.When the outside lights are turnedon, the instrument panel and the var-ious controls located on the dash-board light up.Side and taillights (fig. 103)These come on when you turn ringA from å to 6.
