After switching off a warm engine, the residual

engine heat utilization system may be operated in

conjunction with the vehicle's heater. It serves to

heat the passenger compartment by exploiting

the residual thermal energy contained in the

coolant. The system is operational with the key in

the steering lock at position 0 or 1, or with the

key withdrawn. The coolant temperature must be

higher than 60 °C. The heating duration of the

system depends on the set temperature. The

higher the set temperature, the shorter the

heating duration. Before switching on the residual

engine heat utilization system, the settings of the

heater and ventilation should be noted:

Move the air volume switch to blower

stage "I". A higher blower stage heats

the passenger compartment better, but

puts more strain on the battery.

Set the temperature selectors of the vehicle

heater to the desired passenger compartment

temperature. The in-car temperature

automatically remains at the set level, e.g. 22

°C

In vehicles with automatic climate control,

one of the keys of the automatic climate

control must be pressed (except key ).

Pressing the key is not recommended as

the existing residual thermal energy is used

up more quickly.

Switching on:

Press the switch; the lamp in the switch

lights up.

Switching off:

turning the ignition key to position 2

automatically after approx. 15 minutes

Strona 3/4

automatically when the coolant temperature

drops below approx. 60 °C

with the switch

Strona 4/4
