Windshield wipers offIf the lever is in the 0 position and
you move it upwards, the wipers
will sweep one stroke at a time for
as long as you hold the lever up.
Single sweep positionMove the lever slightly upward
from the 0 position for one sweep
of the wipers. The lever returns
automatically to 0 when released.
Intermittent wiper functionWith the lever in this position, you
can set the wiper interval by twist-
ing the control ring (1) upward to
increase wiper speed or down-
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.

off
Normal (continuous) wiping: Press the
lower section of the switch
Move the lever forward to start the tailgate
washer. After washing the rear window, the
wiper will make several additional sweeps.
Tailgate wiper and reverse gearIf the front wipers are on and the transmission
is put into reverse gear, the tailgate wiper will
go into intermittent wiping function
1.
If the tailgate wiper is already in normal wiping
function, the normal wiping function will con-
tinue.
Rain sensor*
The rain sensor automatically regulates wiper
speed according to the amount of water on the
windshield.
The sensitivity of the sensor can be adjusted
by twisting ring (1) up (the wipers will sweep the
windshield more frequently) or down (the wip-
ers will sweep the windshield less frequently).
Activating the rain sensor:1.
Turn the ignition key to at least position I
and put the windshield wiper lever in posi-
tion 0.
2. Press button (2), see page 71.
> A light in the button will light up to indi-
cate that the rain sensor is active.
Deactivating the rain sensor:
•Press button (2), see page 71.
or
•Move the windshield wiper lever down to
another position. Moving the lever up will
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
windows
Keeping 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 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 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.
Sensors
The 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 weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof* for several minutes before driving
will help release the warm air from the passen-
ger 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 com-
partment as quickly as possible.
Windows and optional moonroof
The 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).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special 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.
Refrigerant
Volvo 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: 1.5 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)
Dual
1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

or off. The "ON" or "OFF" LED will light up to
indicate if the system is switched on or off.
Other functions will still be regulated automat-
ically (if the AUTO switch is on).
Interior air quality sensor*
Some vehicles are equipped with a multifilter
and air quality sensor. The filter separates
gases and particles, thereby reducing 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 ECC system is in the AUTO mode,
the green LED will be on.
Recirculation
Press this switch to engage the recirculation
function (air in the passenger compartment
recirculates – no fresh air enters the compart-
ment). The LED in the switch will light up to
indicate that the function is engaged.
•Use this function if the outside air is con-
taminated with exhaust gases, smoke, etc
or to heat/cool the vehicle quickly.
•Recirculation should not be used for more
than 15 minutes. If your windows begin to
fog or mist, make sure that the recirculation
function is switched off.
•Selecting Defroster automatically
switches recirculation off.
•Timer mode activation: (Vehicles equipped
with the Interior Air Quality system have no
timer mode) Press and hold the recircula-
tion button for at least 3 seconds to acti-
vate a recirculation timer mode. The amber
LED in the recirculation button will flash 5
times to show that the timer mode is being
activated. In timer mode, each time therecirculation button is pressed, the climate
control system will recirculate the air in the
passenger compartment for
5 – 12 minutes, depending on the outside
air temperature, and then revert back to
fresh air.
•Timer mode deactivation: Press and hold
the recirculation button for 3 seconds. The
amber LED in the recirculation button will
illuminate steadily for 5 seconds to show a
return to "normal" mode.
•In normal mode, when the recirculation
button is pressed, the climate control sys-
tem will recirculate the air in the passenger
compartment until the recirculation button
is pressed again.
•Timer mode memory: If the vehicle is
turned off while timer mode is active, timer
mode will still be active when the vehicle is
restarted.
AUTO
This function automatically regulates the
Electronic Climate Control system so that
the selected temperatures are maintained.
The blower, heating, air distribution (air
flow), air conditioning, and optional air qual-
ity sensor are controlled. If you prefer to man-
ually set any of these functions, the remaining
functions will still be controlled automatically.

Engine oil
Although 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 regularly during this period, see
page 215.
Fuel requirements
Deposit 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 exter-
nal 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 effective-
ness of the emission control system and could
result in loss of emission warranty coverage.
State and local vehicle inspection programs
will make detection of misfueling easier, pos-
sibly resulting in emission test failure for mis-
fueled 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 135 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.

06 Starting and driving
Front/rear park assist*
06
154* Option/accessory, for more information, see Introduction.
Front/rear park assist
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
Park assist is available in two versions:
•Rear bumper only
•Front and rear bumpers
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
Function
The system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates.
•The front park assist system is active from
the time the engine is started until the vehi-
cle exceeds a speed of approximately
10 mph (15 km/h). It is also active when the
vehicle is backing up.
•Rear park assist is active when the engine
is running and reverse gear has been
selected.
Rear park assistThe distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The signal comes
from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
Front park assistThe distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
•It may not be possible to combine auxiliary
headlights and front park assist since
these lights could trigger the system's sen-
sors.
Activating/deactivating park assist
The system is activated automatically when the
vehicle is started.
•Press the Park assist button on the center
console (see page 64) to temporarily deac-
tivate the system(s). The indicator light in
the button will go out when the system has
been deactivated.
•Park assist will be automatically reactiva-
ted the next time the engine is started, or if
the button is pressed (the indicator light in
the button will illuminate).
