Ventilated front seats (option)The ventilation system consists of fans in the
seats and backrests that draw air through the
seat upholstery. The cooling effect increases
as the air in the passenger compartment
becomes cooler.
The ventilation is controlled by the ECC sys-
tem, which takes into account the seat tem-
perature, sunlight in the passenger compart-
ment, and the ambient temperature.
The ventilation can be used at the same time
as seat heating.
The ventilation system can be activated when
the engine is running. There are three comfort
levels that produce different cooling and dehu-
midification effects:•
Level three: press the button once for
maximum output – three indicator lights
come on.
•
Level two: press the button twice for a
lower output – two indicator lights come
on.
•
Level one: press the button three times for
the lowest output – one indicator light
comes on.
•
Press the button a fourth time to switch off
the function – the indicator light will go out.
Blower control
Turn the control clockwise to
increase or counterclockwise
to decrease the blower
speed. Pressing the AUTO
switch will automatically reg-
ulate blower speed and over-
ride manual adjustment.
NOTE
If the blower is turned off completely, the air
conditioning is disengaged, which may
result in fogging on the windows.Heated front seats (option)
Press the button once for the
highest heat level – three indi-
cator lights come on.
Press the button twice for a
lower heat level – two indica-
tor lights come on.
Press the button three times for the lowest heat
level – one indicator light comes on.
Press the button four times to switch off the
heat – no indicator lights come on.Heated rear seats

Auto
The function automatically
regulates cooling, heating,
blower speed, recirculation,
and air distribution to main-
tain the chosen temperature.
If you select one or more man-
ual functions, the other func-
tions continue to be controlled automatically.
The air quality sensor is engaged and all man-
ual settings are switched off when AUTO is
pressed. The display shows

Temperature control
The temperatures on the
driver and passenger sides
can be set independently.
When the vehicle is started,
the most recent setting is
resumed.
NOTE
Heating or cooling cannot be speeded up by
selecting a higher/lower temperature than
the actual temperature required.A/C – ON/OFF
The air conditioning is con-
trolled automatically by the
system when the ON light is
on. This cools/heats and
dehumidifies the incoming air.
When the OFF light is on, the
air conditioning is always dis-
engaged. Other functions are still controlled
automatically. When defroster is selected, the
air conditioning system is set for maximum
blower speed and dehumidification.
Defroster
This function defrosts/de-ices
the windshield and front side
windows. The indicator light
in the defroster button lights
when the function is active.
•
Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
Air conditioning can be switched off by
pressing the AC button.
•
Recirculation will not function while defrost
is engaged.
The climate system will return to its previous
settings when the defroster function is
switched off.

Recirculation/air quality system
Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e., no air
from outside the car is taken
into the car when this function is activated. The
indicator light in the button will illuminate when
recirculation is selected.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fog-
ging, or stale air when the recirculation function
is selected by automatically switching off the
function after a certain length of time, depend-
ing on the ambient temperature. Activate/
deactivate the function under Climate control
settings
Recirculation timer. For a
description of the menu system, see
page 120.
NOTE
When Defroster is selected, recirculation is
always deactivated.Interior Air Quality System–IAQS (option)
This system consists of a mul-
tifilter and an air quality sen-
sor. The filter helps remove
gases and particles from the
incoming air, thereby reduc-
ing the amounts of odors and
contaminants entering the
vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-
minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e., no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air. When the AUTO button
is depressed the air quality sensor is always
engaged.
Activating the air quality sensor
Switch between the three
functions by pressing the but-
ton repeatedly.
•
The left orange light comes on – the air
quality sensor is disengaged.
•
The center green light comes on – recircu-
lation not engaged, providing it is not
required for cooling in hot weather.
•
The right orange light comes on – recircu-
lation is engaged.NOTE
•
The air quality sensor should always be
engaged in order to obtain the best air
in the passenger compartment.
•
Recirculation is limited in cold weather
to avoid fogging.
•
If the insides of the windows start fog-
ging, disengage the air quality sensor.
Use the defroster function to increase
airflow to the front, side, and rear win-
dows.

WARNING
•
Exceeding the permissible axle weight,
gross vehicle weight, or any other
weight rating limits can cause tire over-
heating resulting in permanent defor-
mation or catastrophic failure.
•
Do not use replacement tires with lower
load carrying capacities than the tires
that were original equipment on the
vehicle because this will lower the vehi-
cle's GVW rating. Replacement tires
with a higher limit than the originals do
not increase the vehicle's GVW rating
limitations.
Uniform Tire Quality GradingALL PASSENGER VEHICLE TIRES MUST
CONFORM TO FEDERAL SAFETY
REQUIREMENTS IN ADDITION TO THESE
GRADES
Quality grades can be found, where appli-
cable, on the tire sidewall between the tread
shoulder and maximum section width. For
example:
Treadwear 200 Traction AA Temperature ATREADWEARThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov-ernment test course. For example, a tire gra-
ded 150 would wear one and one half (1 1/2)
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and many depart signifi-
cantly from the norm due to variation in driving
habits, maintenance practices and differences
in road characteristics and climate.
TRACTIONThe traction grades, from highest to lowest, are
AA, A, B, and C, as measured under controlled
conditions on specified government test sur-
faces of asphalt and concrete. A tire marked C
may have poor traction performance. The trac-
tion grade assigned to this tire is based on
braking (straight-ahead) traction tests and is
not a measure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is
based on braking (straight-ahead) traction
tests and is not a measure of cornering
(turning) traction.TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a minimum level of performance that
all passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.Snow chains, snow tires, studded tiresSnow chainsSnow chains can be used on your Volvo with
the following restrictions:•
Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•
If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
