WARNING
The heater has two subfunctions that help to
heat the passenger compartment or engine in

starting to refuel.
Make sure that there is enough charge in
the battery if the heater needs to be used.

The heater is fuel-driven and is fitted inside the
engine compartment.
Warning label on fuel filler flap.
When the heater is running, smoke may be
emitted from under the front part of the car
and a low hum may be heard. A ticking
sound from the fuel pump may also be
heard from the rear section of the car. This
is perfectly normal.
The heater uses fuel from the car's normal fuel
tank.
If the car is parked on a steep incline, this may
limit the supply of fuel to the heater.
If the level in the fuel tank is too low then the
heater is switched off automatically and the
driver display shows a message.
Battery and charging
The heater is powered by the car's starter bat-
tery. If the charge level of the starter battery is
too low, then the heater is switched off auto-
matically and the driver display shows a mes-
sage.
Make sure there is enough fuel in the car's
fuel tank if the heater needs to be used.

The parking heater is one of two subfunctions
of the car's heater. The heater is fitted inside
the engine compartment.
Make sure that there is enough charge in
the starter battery if the parking heater
needs to be used.
In locations with combustible or flam-
mable material nearby. Fuel, gas, long
grass, sawdust, etc. may ignite.
When this symbol illuminates in the
driver display, the parking heater
may be active.
When there is a risk that the heater’s
exhaust line may be blocked. For
example, deep snow under the front
part of the car can obstruct the heat-
er’s ventilation.
Repeated use of the parking heater com-
bined with short journeys may discharge
the battery and impair starting.
When the heater is running, smoke may be
emitted from under the front part of the car
and a low hum may be heard. A ticking
sound from the fuel pump may also be
heard from the rear section of the car. This
is perfectly normal.
If the heater is used on a regular basis,
then the car should be driven for the same
amount of time that the heater is used in
order to ensure that the car's battery is
recharged with the same amount of energy
as consumed by the parking heater.
Remember that the preconditioning can be
started by a timer that has been set for a
long time in advance.
WARNING
If there is a smell of fuel, unusual amounts
of smoke, black smoke, or unusual sounds
coming from the parking heater, switch off
the heater and, if possible, pull out its fuse.
Volvo recommends that an authorised
Volvo workshop should be contacted for
repair.
The parking heater starts automatically if the
parking climate's preconditioning* is activated
and the passenger compartment needs to be
heated up.
Depending on factors such as fuel availability,
battery level, passenger compartment tem-
perature and ambient temperature, the heater
has different running times, but never longer
than 30 minutes.
