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 conditions. The f\
ilter 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.

If your vehicle has been parked in the sun in warm weather, opening the \

engaged.
l Use this function if the outside air is contaminated with exhaust gases,\
smoke, etc or to heat/cool the
vehicle quickly.
l 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.
l Selecting Defroster automatically switches recirculation off.
l Timer mode activation: (Vehicles equipped with the Interior Air Quality System have no timer m\
ode)
Press and hold the recirculation button for at least 3 seconds to activa\
te a recirculation timer mode. The
amber LED in the recirculation button will flash 5 times to show that th\
e timer mode is being activated. In
timer mode, each time the recirculation button is pressed, the climate c\
ontrol 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.
l Timer mode deactivation: Press and hold the recirculation button for 3 s\
econds. The amber LED in the
recirculation button will illuminate steadily for 5 seconds to show a re\
turn to "normal" mode.

l In normal mode, when the recirculation button is pressed, the climate co\
ntrol system will recirculate the
air in the passenger compartment until the recirculation button is press\
ed again.
l Timer mode memory: If the vehicle is turned off while timer mode is acti\
ve, timer mode will still be
active when the vehicle is restarted.

Interior Air Quality sensor (option)
Some vehicles are equipped with a multifilter and air quality sensor. Th\
e filter separates gases and particles,
thereby reducing the amounts of odors and contaminants entering the vehi\
cle. 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 compartment \
is recirculated, i.e. no outside air
enters the vehicle. The filter also cleans recirculated passenger compar\
tment air.
When the ECC system is in the AUTO mode, the green LED will be on
.
Operation
Press
to operate the Air Quality sensor (normal setting).
Or:
Select one of the following three functions by pressing
1, 2 or 3 times.
1. The AUT LED lights. The Air Quality sensor is now activated.
2. No LED lights. Recirculation is not activated unless needed to cool t\
he passenger compartment in a warm

climate.
3. The MAN LED lights. Recirculation is now activated.
Keep in mind the following:
l Make it a rule to have the Air Quality sensor activated at all times.
l Recirculation is limited in cold climates to avoid fogging.
l If window fogging occurs, you should deactivate the Air Quality sensor. \
l If fogging occurs, use the defroster functions for the windshield, side \
windows and rear window. See page
53.
l The filter should be changed at the intervals recommended in the mainten\
ance schedule. However, if the
vehicle is used in a severely contaminated environment, it may be necess\
ary to change the filter more
frequently.

pg. 91 Starting and driving
General information
Economical driving conserves natural resources
Better driving economy may be obtained by thinking ahead, avoiding rapid\
starts and stops and
adjusting the speed of your vehicle to immediate traffic conditions. Obs\
erve the following rules:
l Bring the engine to normal operating temperature as soon as possible by \
driving with a light foot on
the accelerator pedal for the first few minutes of operation. A cold eng\
ine uses more fuel and is subject
to increased wear.
l Whenever possible, avoid using the vehicle for driving short distances. \
This does not allow the engine
to reach normal operating temperature.
l Drive carefully and avoid rapid acceleration and hard braking.
l Use the transmission's (D)rive position as often as possible and avoid using "kickdown" to help
improve fuel economy.
l Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the vehicle.
l Maintain correct tire pressure. Check tire pressure regularly (when tir\
es are cold).
l Remove snow tires when threat of snow or ice has ended.
l Note that roof racks, ski racks, etc, increase air resistance and also f\
uel consumption.
l At highway driving speeds, fuel consumption will be lower with the air c\
onditioning on and the
windows closed than with the air conditioning off and the windows open. \
l Using the onboard trip computer's fuel consumption modes can help you le\
arn how to drive more
economically.
Other factors that decrease gas mileage are:
l Dirty air cleaner
l Dirty engine oil and clogged oil filter
l Dragging brakes
l Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard\
Maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, \
which means that the steering
wheel has to be turned more than might seem appropriate for the curvatur\
e of a bend. This ensures good
stability and reduces the risk of rear wheel skid. Remember that these p\
roperties can alter with the
vehicle load. The heavier the load in the cargo area, the less the tende\
ncy to understeer.

Information booklet provides a comprehensive periodic maintenance schedu\
le up to 150,000 miles
(240,000 km) of vehicle maintenance. 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 120,000 miles (193,000 km). The \
filter is replaced as a complete
unit. Replace more frequently if contaminated fuel is introduced into th\
e tank, or if there is reason to
suspect that this has occurred.
Fuel system, including filler cap, tank, 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 vehicle is refueled,
the Check Engine light (Malfunction Indicator) may indicate a fault. H\
owever, your vehicle's
performance will not be affected. Use only Volvo original or approved fu\
el filler caps.
Timing belt
For proper functioning of the engine and emission control systems, the t\
iming belt and belt pretensioner
must be replaced every 120,000 miles (193,000 km) or 10 years, whichev\
er occurs first. 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 120,000 miles (193,000 km), and again at 45,0\
00 miles (72,000 km).
Spark plugs
The spark plugs should be replaced every 60,000 miles (96,000 km).
Under normal driving conditions, spark plugs require no maintenance betw\
een replacement intervals.
