Engine block heater and passenger
compartment heater*
Preconditioning prepares the heater, engine
and passenger compartment before depar-
ture so that both wear and energy needs dur-
ing the journey are reduced. Warming up your
car will also extend the driving distance.
The heater can be started directly (p. 138) or
with a timer (p. 139).
The heater cannot start if the outside tem-
perature exceeds 15 °C. At –5 °C or lower the
maximum running time of the heater is 50
minutes.
WARNING
Do not use the fuel-driven heater indoors.
Exhaust gases are secreted.
NOTE
When the fuel-driven auxiliary heater is
active there may be smoke from under-
neath the car, which is perfectly normal.
Refuelling
Warning label on fuel filler flap.
WARNING
Fuel which spills out could be ignited.
Switch off the fuel-driven auxiliary heater
before starting to refuel.
Check in the combined instrument panel
that the heater is switched off. The heat
symbol is shown when it is operating.
Parking on a hill
If the car is parked on a steep hill, the front of
the car should point downhill to ensure that
there is a supply of fuel to the fuel-driven
heater.
Battery and fuel
If the battery has insufficient charge or the
fuel level is too low, the heater will be
switched off automatically and a message
appears in the display. Acknowledge the
message by pressing the indicator stalk
(p. 106) OK button once.
IMPORTANT
Repeated use of the heater in combination
with short driving distances may cause low
charge level in the starter battery, this can
lead to the heater stopping or never star-
ting. In the worst case, engine starting will
not be possible.
The car should be driven for the same time
as the heater is used to ensure that the
starter battery is recharged adequately to
replace the energy consumed by the
heater when it is used on a regular basis.
The heater is used for a maximum of 50
minutes each time.
