In production, Volvo has partly or completely  phased out several chemicals including freons, lead chromates,
naphtanates, asbestos, mercury and  cadmium; and  reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a  three-way catalytic converter with a  Lambda
sond, now called oxygen  sensor, in 1976. The current version  of this  highly efficient system reduces emissions  of
harmful substances (CO, HC, NOx) from  the exhaust pipe by approximately 95% and  the search to eliminate the
remaining emissions  continues. Volvo is the only automobile manufacturer to offer  CFC-free retrofit kits  for the air
conditioning system for all models as far back as the M/Y 1975 240. Advanced electronic  engine controls, refined
purification systems and  cleaner  fuels  are bringing us closer to our goal.
After Volvo cars and  parts  have fulfilled their use, recycling is the next critical step in completing the life cycle. The
metal content  is about 75% of the total weight of a  car, which  makes the car among the most  recycled  industrial
products.  In order to have efficient and  well controlled recycling, many Volvo variants have printed dismantling
manuals, indicating the weight and  material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz.  (50 grams) are marked with international symbols that indicate how the component  is to be
sorted  for recycling.
In addition to continuous environmental refinement of conventional gasoline-powered  internal combustion engines,
Volvo is actively looking at advanced technology  alternative-fuel vehicles.
When you drive a  Volvo, you become our partner in the work to lessen  the car's impact on the environment.
To reduce your vehicle's environmental impact, you can:
 Maintain proper air pressure in your tires. Tests have shown decreased  fuel economy with improperly  inflated tires
 Follow the recommended maintenance schedule in your Warranty and  Service Records Information booklet.
 Drive at a  constant speed
 See  an  authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator) lamp
illuminates,  or stays on after the vehicle has started
 Properly  dispose of any  vehicle related waste such as used motor oil, used batteries, brake pads, etc.
 When cleaning your car, use Volvo's  own car care products,  all of which  have systematically been adapted to the
environment.
PremAir®
On the surface  of the radiator in the engine compartment, there is a  special 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.
PremAir  is a  registered  trademark of Engelhard Corporation.

pg. 48 Electronic Climate Control  (ECC)
 AUTO
This function automatically  regulates the Electronic Climate Control system so that the selected temperatures are
maintained.  The blower, heating,  air distribution (air flow) and  air conditioning are controlled. If you prefer  to
manually set any  of these functions, the remaining functions will still  be  controlled automatically.  Pressing the AUTO
button overrides any  settings that were  previously made manually. 
 Temperature
These controls are used to individually set the temperature for both sides of the passenger  compartment. Please note
that the compartment will not be  heated or cooled faster by setting the temperature higher or lower than necessary.  
Set the control to the temperature you prefer.
 Defroster
This function demists/de-ices the windshield and  front  side windows. The LED  in the switch will light up to indicate
that the defrost function is engaged. Blower  speed increases automatically  and  the air in the passenger  compartment is
dehumidified. Recirculation will not function while defrost is engaged.
 Heated rear window/sideview mirrors
This function demists/de-ices the rear window and  sideview mirrors.  The LED  in the switch will light up to indicate
ProCarManuals.com 

that the heating  function is engaged. See  page 39 for additional information on this  function.
CAUTION:
Never  use ice scrapers made of metal as they can easily scratch the mirror surface.
pg. 49 Electronic Climate Control  (ECC) - manual settings
 Recirculation (see also page 51)
Press this  switch to engage the recirculation function (air in the passenger  compartment recirculates - no fresh air
enters the compartment). The LED  in the switch will light up to indicate that the function is engaged.
 Use this  function if the outside air is contaminated with exhaust gases, smoke, etc or to heat/cool the car 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:  (Cars with Interior Air Quality system have no timer mode) Press and  hold the recirculation
button for at least 3 seconds to activate 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 the time mode, each time the recirculation button is
pressed, the climate  control system will recirculate the air in the passenger  compartment for 5 to 12 minutes, depending
on the outside air and  then revert back to fresh air.
Timer mode deactivation:  Press and  hold the recirculation button for at least 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 system will recirculate the air in the
passenger  compartment until the recirculation button is pressed again.
Timer mode memory:  If the car is turned off while timer mode is active, timer mode will still  be  active when the
car is restarted.
 Heated front seats (option)
Please see page 39
 for more information on this  function.
 Air  flow
Press AUTO  to automatically  regulate air flow or press any  combination of the controls shown in the illustration to
manually adjust air flow. An LED  in the switch will light up if an  air flow control has been pressed.
 Air  conditioning ON/OFF
ProCarManuals.com 

Press the switch to turn the air conditioning on 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 automatically  (if  the AUTO switch is on).
 The air conditioning functions only at temperatures above 32° F (0° C).
 While  the Defroster function is selected, the air conditioning is temporarily activated to dehumidify the air, even if
you have manually switched the air conditioning off. This will only function if the blower is not  switched off.
 Blower control
Turn  the control clockwise to increase or counterclockwise to decrease  the 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 orange LED  next to the control will light
up) will turn both the blower and  the air conditioning off.
pg. 50 Climate control system  - general information
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 filter  cannot be  cleaned and  therefore should always be
replaced  with a  new one.
Sensors
The sunlight sensor on the dashboard and  passenger  compartment temperature sensor in the ECC  control panel should
not be  covered in any  way as this  could cause incorrect information 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 windows and  sun roof (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  sun roof and  use the recirculation function for several minutes to enable the air conditioning to
cool the compartment as quickly as possible.
Windows  and optional  moonroof 
The ECC  system will function best if the windows 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 disengaged during full-throttle acceleration.
ECC maintenance  
All maintenance on the climate  control systems should be  carried out by an  authorized Volvo service technician only.
Refrigerant
ProCarManuals.com 

Volvo cares about the environment. The air conditioning system in your car contains a  CFC-free refrigerant - R134a
(HFC134a). This substance will not deplete the ozone layer. The system contains 2.2 lbs (1000 g) R134a and  uses
PAG  oil.
Passenger compartment blower  
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically,  and  run for five
minutes, to remove condensation in the A/C evaporator.
pg. 51 Electronic Climate Control  (ECC) - with  Interior Air Quality system  (option)
Interior Air  Quality system (option)
Some cars 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 car. The air quality sensor detects increased levels of
contaminants in the outside air. When the air quality 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 car. The filter  also cleans
recirculated passenger  compartment air. When the Air quality sensor is activated, the LED  AUT comes on in the
recirculation button 
Operation:
Press
 to activate the Air quality sensor (normal setting).
Or select one  of three functions by pressing 
 
1. Press 
 the LED  AUT  comes on.
The Air quality sensor is now activated. 
2. Press 
 no LED  is lighted.
Recirculation not activated. 
3. Press 
the LED  MAN  comes on. Recirculation is now activated. You can switch between these three functions
by repeatedly pressing 
Keep the following  in mind:
 Make it a  rule to have the air quality sensor activated at all times.
 Recirculation is limited in cold climates to avoid misting  up.
 If misting  occurs, you should deactivate the Air quality sensor.
 If the windows mist up, you can also use the windshield and  side window defroster functions. See  page 48.
 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 environment, it may be  necessary  to change the filter  more
frequently.

· Press the Park assist button on the center  console (see page 31) to temporarily deactivate the system(s). 
· The indicator light in the button will go out when the system(s) have been deactivated. 
· If the vehicle is equipped with front  and  rear park assist, both systems will be  deactivated by pressing the button.
NOTE: 
It may be  necessary  to deactivate one  or both of the park assist systems in certain cases. 
· Rear park assist:  towing a  trailer, carrying bicycles in a  rear-mounted carrier, etc, could trigger the rear park assist
system's sensors.  
· Front  park assist:  it may not be  possible to combine  auxiliary headlights and  front  park assist since these lights
could trigger the system's sensors.
Faults in the system  
If a  fault should occur in the system, the LED  in the button will be  switched off and  a  message will be  displayed in the
text window.
Cleaning the sensors
For the system to function properly, the sensors  in the front  and/or rear bumpers  should be  kept clean. They can be
cleaned with car washing detergent and  a  sponge.
WARNING!
These systems are designed to be  a  supplementary aid when parking the vehicle. They are not, however,  intended  to
replace  the driver's attention and  judgement.
pg. 84 Driving economy
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. Observe the following rules:
 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 engine uses more fuel and  is subject to increased wear.
 Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
 Drive carefully and  avoid rapid acceleration and  hard braking.
 Do not exceed posted speed limits.
 Avoid carrying unnecessary  items (extra load) in the car.
 Maintain correct tire pressure. Check tire pressure regularly (when tires are cold).
 Remove snow tires when threat of snow or ice has ended.
 Note  that roof racks, ski racks, etc., increase air resistance  and  also fuel consumption.
 Avoid using automatic  transmission kickdown  feature unless necessary.
 Avoid using the air conditioning when it is not required. When engaged, the A/C compressor places an  additional
load on the engine. However, at higher driving speeds, fuel consumption will be  lower with the air conditioning on and
the windows closed than with the air conditioning off and  the windows open.
 Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease  gas mileage are:
 Dirty air cleaner
 Dirty engine oil and  clogged oil filter
 Dragging brakes
 Incorrect front  end  alignment
Some of the above mentioned items and  others  are checked at the standard Maintenance Service intervals.
ProCarManuals.com 

NOTE: Vehicles equipped with automatic  transmissions  should use (D)rive  as often as possible and  avoid using
"kickdown"  to help improve fuel economy.
Cooling system  
The risk for engine overheating is greatest, especially in hot weather, when:
 Towing a  trailer up steep inclines for prolonged periods  at wide  open  throttle and  low engine rpm.
 Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
 To avoid overheating, the following rules  should be  followed:
Do not drive for prolonged periods  at engine speeds above 4500 rpm if you are towing a  trailer in hilly terrain.
 Reduce speed when towing a  trailer up long, steep inclines. The risk of overheating can be  reduced by switching off
the air conditioning system for a  short time.
 Do not let the engine idle unnecessarily  for prolonged periods.
 Do not mount auxiliary lamps in front  of the grill.
When the risk of overheating is imminent, or in the event of overheating (the temperature gauge goes repeatedly into,
or stays continually in, the red section), the following precautions should be  taken:
 Switch off the air conditioning system.
 Pull off the road, away from  traffic,  stop the car and  put the gear selector into Park. Do not stop the engine!
 Switch the heater  to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
 If the warning light in the center  of the instrument panel is red, and  the message "Coolant level  low stop engine"  is
displayed, switch off the engine as soon as possible.
WARNING!
Do not remove coolant  expansion tank cap. The coolant  will be  extremely hot.
If necessary,  see page 132
 for information on checking and  topping-up the coolant  level.
