Installation instructions

Auxiliary heater 83.2

Model 140 left-hand drive

The auxiliary heater installed under the right-

hand front fender is integrated into the coolant

circuit of the engine. It serves not only to heat

the passenger compartment, but also to warm

up the engine to ensure reliable start-up even at

extremely low outside temperatures. The

auxiliary heater is switched on and off by means

of a timer in the passenger compartment. The

timer can be used to preselect the start of

heating within the next 24 hours, or up to 7

days in advance.

Observe all licensing regulations. In the Federal Republic of Germany, vehicles retrofitted with the auxiliary heater require renewed official approval.

The auxiliary heater must not be operated in sealed rooms without waste air extraction or at filling stations.

Untreated body parts, e.g. around drilled holes, must be coated with zinc dust paint.
