ward to decrease the speed.
Windshield washer/headlight washer
(certain models)When the lever is pulled to wash the wind-
shield, high pressure jets mounted in the
bumper will spray the headlights.
CAUTION
•
Use ample washer fluid when washing
the windshield to avoid scratching the
glass. The windshield should be thor-
oughly wet when the wipers are in oper-
ation.
•
Before using the wipers, ice and snow
should be removed from the wind-
shield/rear window. Be sure the wiper
blades are not frozen in place.
•
To conserve washer fluid in driving condi-
tions where the windshield washers are
used frequently, the headlights will only be
washed once for every five times the wind-
shield is washed within a 10-minute period.
•
A short pull on the lever will wash the wind-
shield only.
•
When approximately 1 US quart (1 liter)
remains in the washer fluid reservoir, the
headlights will not be washed when the
lever is pulled to conserve washer fluid for
the windshield.

not deactivate the rain sensor. Doing so
will cause the wipers to sweep the wind-
shield until the lever is released, at which
time the wipers return to rain sensor mode.
The rain sensor is also deactivated when the
key is removed from the ignition.CAUTION
The rain sensor should be deactivated when
washing the vehicle in an automatic car
wash, etc. If the rain sensor function is left
on, the wipers will start inadvertently in the
car wash and could be damaged.

Condensation on the inside of the
windowsKeeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.Cabin air filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
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.
SensorsThe sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.Parking the vehicle in warm weatherIf your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof (option) for several minutes before
driving will help release the warm air from the
passenger compartment. When the engine is
running, close the windows and moonroof and
use the recirculation function for several
minutes to enable the air conditioning to cool
the compartment as quickly as possible.Windows and optional moonroofThe ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
AccelerationThe air conditioning is momentarily disen-
gaged during full-throttle acceleration.Climate control maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.RefrigerantVolvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.4 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
8-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

06 Starting and drivingGeneral information
06128
Engine oilAlthough some oil consumption occurs during
normal engine operation, more oil is consumed
when the engine is new as the internal parts
generate higher friction while wearing-in to
each other. From the time the engine is new
until the first maintenance is performed, the oil
consumption could be higher than normal. For
this reason, it is especially important to check
the oil every time you refuel your vehicle during
this period, see page 209.Fuel requirementsDeposit control gasoline (detergent
additives)Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of
external fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense 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 effec-
tiveness of the emission control system and
could result in loss of emission warranty cov-
erage. State and local vehicle inspection pro-
grams will make detection of misfueling easier,
possibly resulting in emission test failure for
misfueled vehicles.
NOTE
Some U.S. and Canadian gasolines contain
an octane enhancing additive called methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician for maintenance.
Gasoline containing alcohol and ethers"Oxygenated fuels"
Some fuel suppliers sell gasoline containing
"oxygenates" which are usually alcohols or
ethers. In some areas, state or local laws
require that the service pump be marked indi-
cating use of alcohols or ethers. However,
there are areas in which the pumps are
unmarked. If you are not sure whether there is
alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
on page 129 must still be met.
Alcohol – Ethanol: Fuels containing up to 10%
ethanol by volume may be used. Ethanol may
also be referred to as Ethyl alcohol, or "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.
