CLIMATE
Parking heater*
The parking heater heats the passenger com-
partment as necessary before driving if the
car's preconditioning is activated.
The parking heater is one of two subfunctions
of the car's heater. The heater is fitted in the
front right-hand wheel housing.
When this symbol illuminates in the
driver display, the parking heater
may be active.
NOTE
When the heater is running, smoke may be
emitted from the right-hand front wheel
housing 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 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.

NOTE
Make sure there is enough fuel in the car's
fuel tank if the parking heater needs to be
used.
Make sure that there is enough charge in
the starter battery if the parking heater
needs to be used.
IMPORTANT
Repeated use of the parking heater com-
bined with short journeys may discharge
the battery and impair starting.
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.
WARNING
Do not use preconditioning if the car is
equipped with a heater*:
In unventilated spaces indoors.
•
Exhaust gases are emitted if the heater
starts.
In locations with combustible or flam-
•
mable material nearby. Fuel, gas, long
grass, sawdust, etc. may ignite.
When there is a risk that the heater's
•
exhaust line may be blocked. For
example, deep snow inside the front
right-hand wheel housing can obstruct
the heater's ventilation.
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.
