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\
. The filter should be replaced
more often when driving under dirty and dusty conditions. The filter can\
not 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\

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

Temporarily turning off the alarm sensor(s) - accessory
This button will only be found in cars equipped with the optional inclin\
ation and/or movement sensors.
In certain situations it may be desirable to turn off the optional incli\
nation and movement alarm sensors
if, for example, you drive your car onto a ferry where the rocking of th\
e boat could trigger the alarm or if
a pet is left in the car with the doors locked.

pg. 84 Fuel requirements
Fuel requirements
Octane rating: Volvo engines are designed for optimum performance on unleaded premium\
gasoline
with an octane rating AKI of 91, or above. AKI (ANTI KNOCK INDEX) is a\
n average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON + MON/2). T\
he minimum octane
requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additive\
s. These additives have shown
to be effective in keeping injectors and intake valves clean. Consistent\
use of deposit control gasolines
will help ensure good driveability and fuel economy. If you are not sure\
whether the gasoline contains
deposit control additives, check with the service station operator.
Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleade\
d gasoline. U.S. and Canadian
regulations require that pumps delivering unleaded gasoline be labelled \
"UNLEADED". Only these
pumps have nozzles which fit your car's filler inlet. It is unlawful to \
dispense leaded fuel into a vehicle
labelled "unleaded gasoline only". Leaded gasoline damages the three-way\
catalytic converter and the
heated oxygen sensor system. Repeated use of leaded gasoline will lessen\
the effectiveness of the
emission control system and could result in loss of emission warranty co\
verage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly r\
esulting in emission test failure
for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
service.

pg. 130 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
