CONTROLS AND EQUIPMENT
AUXILIARY HEATER* (Syncro models only)
The auxiliary heater* heats the coolant in the heating circuit and supplies the heat exchanger in the normal heating system
and the additional heat exchanger* for the
passenger compartment heating with heated coolant.
The system is switched off and on or the
switch-
on time preselected by means of a
switch and indicator unit located on the left under the instrument panel.
Air distribution and regulation is done with the controls of the normal heating and
ven­

tilation system (see "Ventilation/Heating"
on page 51).
The auxiliary heater can be used with vehicle stationary or when it is moving.
When vehicle is stationary, the heater only runs for a maximum of 30 minutes in order
to avoid draining the battery. It also switches off automatically when a coolant
temperature of 80° C (175° F) is reached.
When the coolant temperature drops below 70° C (158° F) the heater is auto­matically switched on again. The heater runs on fuel from the vehicle
tank and uses up to half a litre (one quart) per hour. Controls
A - Buttons for setting time and
preselected time
B - Indicator lamp for preselected time
C - Preselected time D - Display
E - Actual time
F - Heater on/off
G - Warning lamp (Heater on)
