Condensation on the inside of the windows
Keeping the insides of the windows clean will help reduce the amount of \
condensation that forms on the
windows. Use a commercial window cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of the windshield free of \
snow.
Cabin air filter
Replace the cabin air filter with a new one at the recommended intervals\
. Please refer to your Warranty
and Service Records Information booklet, or consult your Volvo retailer \
for these intervals. The filter
should be replaced more often when driving under dirty and dusty conditi\
ons. The filter cannot be
cleaned and therefore should always be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and passenger compartment temperatu\
re sensor in the ECC control
panel should not be covered in any way as this could cause incorrect inf\
ormation to be sent to the ECC
system.
Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the wind\
ows and moonroof (option) for
several minutes before driving will help release the warm air from the p\
assenger compartment. When
the engine is running, close the windows and moonroof and use the recirc\
ulation function for several
minutes to enable the air conditioning to cool the compartment as quickl\
y as possible.

Blower control
Turn the control clockwise to increase or counterclockwise to decrease t\
he blower speed. Pressing the
AUTO switch will automatically regulate blower speed and override manual\
adjustment.
NOTE: Turning the blower control counterclockwise as far as possible (an oran\
ge LED next to the
control will light up) will turn both the blower and the air conditioni\
ng off.

pg. 51 Electronic Climate Control (ECC) with Interior Air Quality syst\
em (option)
Interior Air Quality system (option)
Some cars are equipped with a Multifilter and Air quality sensor. The fi\
lter separates gases and particles,
thereby reducing the amounts of odors and contaminants entering the car.\
The Air quality sensor detects
increased levels of contaminants in the outside air. When the Air qualit\
y sensor detects contaminated
outside air, the air intake closes and the air inside the passenger comp\
artment is recirculated, i.e. no
outside air enters the car. The filter also cleans recirculated passenge\
r compartment air. When the Air
quality sensor is activated, the LED AUT comes on in

Operation:
Press to activate the Air quality sensor (normal setting).
Or select one of three functions by pressing

You can switch between these three functions by repeatedly pressing

Keep the following in mind:
l Make it a rule to have the Air quality sensor activated at all times.
l Recirculation is limited in cold climates to avoid misting up.
l If misting occurs, you should deactivate the Air quality sensor.
l If the windows mist up, you can also use the windshield and side window \
defroster functions. See
page 49.
l The filter should be changed at the intervals listed in the Warranty and\
Service Records Information
booklet. However, if the car is used in a severely contaminated environm\
ent, it may be necessary to
change the filter more frequently.

pg. 132 Fuel/emissions systems
Fuel system
The fuel system continually compensates for variation in engine load, sp\
eed and temperature. A mass air
flow sensor continuously measures the inducted air and makes rapid adjus\
tments for changes in air
temperature and density, to balance fuel economy, emissions, and engine \
power requirements.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and impr\
ove fuel economy. The heated
oxygen sensor monitors the composition of the exhaust gases leaving the \
engine. The exhaust gas
analysis is fed into an electronic module. This adjusts the air/fuel rat\
io to improve combustion and
reduce the three major pollutants (hydrocarbons, carbon monoxide, and o\
xides of nitrogen (NOx)) via a
three-way catalytic converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevent\
s crankcase gases from being
released into the atmosphere. Instead, the crankcase gases are routed to\
the intake manifold and
cylinders.
PremAir®
On the surface of the radiator in the engine compartment, there is a spe\
cial coating called PremAir®.
PremAir® works as a catalytic converter, converting most of the ozone\
passing through the radiator into
oxygen, thereby reducing harmful ground-level ozone.
Evaporative control system
The car is equipped with an evaporative control system, which prevents g\
asoline vapor from being
released into the atmosphere.
The system consists of a fuel tank with filler pipe and cap, two rollove\
r valves, a Fill Limit Vent Valve
(FLVV), vapor vent lines, a charcoal canister, a purge line, and a pur\
ge control valve and engine
connections. In addition, there is a pressure sensor connected to the fu\
el tank and a filter-protected
Canister Close Valve (CCV) on the atmospheric side of the canister, fo\
r system diagnosis.
The gasoline vapor is channeled through the rollover valves and the FLVV\
via the vapor vent lines into
the charcoal canister, where it is stored. When the engine is started, t\
he gasoline vapor is drawn from the

coolant circulation between the engine and the expansion tank during eng\
ine warm up and cooling.
Changing coolant
Normally, the coolant does not need to be changed. If the system must be\
drained, consult your Volvo
retailer.
NOTE: Do not top off with water only. This reduces the rust-protective and ant\
ifreeze qualities of the
coolant and has a lower boiling point. It can also cause damage to the c\
ooling system if it should freeze.
Top off with Volvo Genuine Coolant/Antifreeze only.
CAUTION:
The cooling system must always be kept filled to the correct level. If i\
t is not kept filled, there can be
high local temperatures in the engine which could result in damage. Diff\
erent types of antifreeze/coolant
may not be mixed.
WARNING!
Never remove the radiator cap while the engine is warm. Wait until the c\
ar
cools.


pg. 134 Emissions maintenance
Periodic maintenance helps minimize emissions
Periodic maintenance will help keep your vehicle running well. Your Warr\
anty and Service Records
Information booklet provides a comprehensive periodic maintenance schedu\
le up to 150,000 miles
(240,000 km) of vehicle service. The schedule includes components that\
affect vehicle emissions. This
page describes some of the emission-related components.
Engine air filter
The engine air filter cleans particles from air entering the engine. Rep\
lace the engine air filter cartridge
with a new one every 37,500 miles (60,000 km) under normal driving con\
ditions. Replace the cartridge
more often when the vehicle is driven under dirty and dusty conditions. \
The cartridge cannot be cleaned,
and should always be replaced with a new one.

Fuel filter
The fuel filter should be replaced at 105,000 miles (168,000 km) or at\
120,000 miles (193,000 km) for
the 2.5T engine on AWD models. The filter is replaced as a complete unit\
. Replace more frequently if
contaminated fuel is introduced into the tank, or if there is reason to \
suspect that this has occurred.
Fuel system, including filler cap, tank and lines and
connections
The ability of the fuel system to contain hydrocarbons depends upon a le\
ak-free system. Inspect fuel
lines every 30,000 miles (48,000 km). Check for proper sealing of the \
fuel filler cap which contains "O"
ring seals.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running\
when the car is refueled, the
Check Engine light (Malfunction indicator) may indicate a fault. Howev\
er, your vehicle's performance
will not be affected. Use only Volvo original or approved fuel filler ca\
ps.
Timing belt
For proper functioning of the engine and its emission control systems, t\
he timing belt and belt tensioner
must be replaced every 105,000 miles (168,000 km) or at 120,000 miles \
(193,000 km) for the 2.5T
engine on AWD models. Engine damage will occur if the belt fails.
PCV system
(on turbocharged models)
The nipple in the intake manifold and the filter at the end of the PCV h\
ose in the air cleaner should be
inspected and cleaned at 105,000 miles (168,000 km) or at 120,000 mile\
s (193,000 km) for the 2.5T
engine on AWD models, and again at 150,000 miles (240,000 km).
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 km) unde\
r normal driving conditions.
City driving or fast highway driving may necessitate replacement sooner.\
Under normal driving conditions, spark plugs require no maintenance betw\
een replacement intervals.
When installing new plugs, be sure to use the right type and to tighten \
them correctly. When changing
the plugs, clean the terminals and rubber seals. Also check that the sup\
pressor connectors are in good
condition. Cracked or damaged connectors should be replaced.

Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the eng\
ine inlet manifold and a
charge air cooler to cool the compressed inlet air. The resulting increa\
se in air flow raises pressure in the
intake manifold and increases engine power over that developed by A norm\
ally-aspirated engine. The
charge air cooler (which resembles a radiator) is located between the \
turbo-compressor and inlet
manifold.
