Starting engine in cold weather

The preheating function should be used when the
coolant temperature is below ±0 °C (+32 °F).
1 Turn the ignition key to running position (1).
2 Press the switch for the preheating. The system
can only be activated when the coolant temperature
is below +20 °C (+68 °F) and at the most twice
during the same starting occasion.
3 The preheating is now engaged and the control lamp is alight.
(The length of time during which the element remains connected is
determined by the coolant temperature).
4 When the control lamp is extinguished, the engine is started by
turning the ignition key to starting position (3).
5 The preheating is automatically reconnected at a coolant
temperature below +20 °C (+68 °F) whereby the control lamp lights
up.
VARNINGI
Starting gas (ether etc.) must not be used at the same
time as the preheating element
NOTE: If the control lamp continues to light after a period of
50 seconds, the preheating is still connected. Should this be
the case, check the function of the element as there Is a risk
of overheating.
Leave the engine running at low idling for 30 seconds so
that the oil in the engine, transmission, hydraulic system and
axles has warmed up and become sufficiently fluid to provide
proper lubrication.
To race the engine immediately after it has been started
may also endanger the lubrication and cooling of the
turbocharger with great risk of bearing seizure as a
consequence.
