The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
NOTE
There are different types of cabin air filters.
Ensure that the correct type is installed.Interior Air Quality System (IAQS)A multifilter helps reduce gases and particles
in the incoming air, thereby reducing the levels
of odors and contaminants entering the vehi-
cle. The air quality sensor detects increased
levels of contaminants in the outside air. When
the air quality sensor detects contaminated
outside air, the air intake closes and the air
inside the passenger compartment is recircu-
lated, i.e. no outside air enters the vehicle. The
filter also cleans recirculated passenger com-
partment air.
NOTE
Contact your Volvo retailer for IAQS air filter
replacement intervals.

06 Maintenance and specificationsWheels and tires
06244
IntroductionYour vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Certain models are equipped with "all-season"
tires, which provide a somewhat higher degree
of road holding on slippery surfaces than tires
without the "all-season" rating. However, for
optimum road holding on icy or snow-covered
roads, we recommend suitable winter tires on
all four wheels.
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration
for hydroplaning resistance. As such, they
may be more susceptible to road hazard
damage and, depending on driving condi-
tions, may achieve a tread life of less than
20,000 miles (30,000 km). Even if this vehi-
cle is equipped with Volvo’s advanced AWD
or DSTC system, these tires are not
designed for winter driving, and should be
replaced with winter tires when weather
conditions dictate.When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's roadholding and handling characte-
ristics.Storing wheels and tiresWhen storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline, oils,
etc.Tread wear indicator
G021829
Tread wear indicatorThe tires have wear indicator strips running
across or parallel to the tread. The letters TWI
are printed on the side of the tire. When
approximately 1/16 " (1.6 mm) is left on the
tread, these strips become visible and indicate
that the tire should be replaced. Tires with less
than 1/16 " (1.6 mm) tread offer very poor trac-
tion.
