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
