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.

This light indicates that the rear fog light is on.
Malfunction indicator lamp
On-Board Diagnostic II (OBDII): As you drive, a computer called "OBDII" monitors your car's engine, transmission,
electrical and emission systems. The CHECK ENGINE light will light up if the computer senses a condition that
potentially may need correcting. When this happens, please have your car checked by a Volvo retailer as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cleanliness, and driveability. Extended driving
without correcting the cause could even damage other components in your car.
Canadian models are equipped with this warning light:
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo
original or approved fuel filler caps.
Anti-lock Brake System ABS
If the warning light comes on, there is a malfunction of the ABS system (the standard braking system will still
function). The vehicle should be driven to a Volvo retailer for inspection. See page 114
for additional information.
Stability Traction Control (STC) system (option), or Dynamic Stability and Traction Control (DSTC) system
(option)
An indicator light will flash when STC or DSTC is actively working to stabilize the car. See pages 115-116
for more
detailed information.
Turn signal indicator - trailer (certain models)
If you are towing a trailer, this light will flash simultaneously with the turn signals on the trailer. If the light does not
flash when signaling, neither the trailer's turn signals nor the car's turn signals are functioning.
Seat belt reminder
This symbol lights up to indicate that the driver has not fastened his/her seat belt.

exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
pg. 90 Refueling
Refueling
The fuel tank holds approximately:
Front wheel drive, non-turbo models - 18.5 US gal. (70 liters)
All turbo models - 18 US gal. (68 liters)
with sufficient volume left over to accommodate possible expansion of the fuel in hot weather. Be aware that the
"usable" tank capacity will be somewhat less than the specified maximum. When the fuel level is low, such factors as
ambient temperature, the fuel's "Reid vapor pressure" characteristics, and terrain can affect the fuel pump's ability to
supply the engine with an adequate supply of fuel. Therefore, it is advisable to refuel as soon as possible when the
needle nears the red zone, or when the fuel warning light comes on.
Fuel filler door
Press the button on the light switch panel (see illustration on page 35
) when the car is at a standstill to unlock the fuel
filler door. Please note that the fuel filler door will remain unlocked until the car begins to move forward. An audible
click will be heard when the fuel filler door relocks.
If you intend to leave your car while it is being refueled, this features enables you to lock the door/tailgate while
leaving the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refueling. The central locking button does not lock the
fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed after refueling.
Open the fuel filler cap slowly during hot weather conditions.

Sport mode (R-models only)
R-models are equipped with a (S)port button that can be used to engage/disengage the Sport shifting mode. An
indicator light in the button will go on when Sport mode is engaged.
With Sport mode engaged, the transmission will shift up at higher rpm in first and second gears, and will also shift
down at higher rpm for more immediate engine response during acceleration and deceleration.
pg. 98 All Wheel Drive - option
All Wheel Drive (AWD) - general information
Your Volvo can be equipped with permanent All Wheel Drive, which means that power is distributed automatically
between the front and rear wheels. Under normal driving conditions, most of the engine's power is directed to the front
wheels. However, if there is any tendency for the front wheels to spin, an electronically controlled coupling distributes
power to the wheels that have the best traction.
Tire dimensions
Volvo recommends that you always drive on tires of the same brand, size, construction (radial), tread pattern, load-,
speed-, traction-, temperature-, and treadwear rating. Never drive on mixed tires, except for brief periods when the
temporary spare tire is in use.
Always use properly inflated tires of correct dimensions. Tire size and inflation pressures are shown on the tire
inflation pressure placards, located on the driver's side B-pillar (the structural member at the side of the vehicle, at the
rear of the driver's door opening), or on the inside of the fuel filler door on Canadian models.
Temporary Spare
The temporary spare tire is for temporary, low-speed, short-distance use only. Replace it with a full-sized tire as soon
as possible. Do not drive on the temporary spare at speeds above 50 m.p.h. (80km/h) or for distances greater than 50
miles (80 km).
Never install snow chains on a temporary spare.
pg. 99 Four -C active chassis system (option)
Four-C
The FOUR-C (Continuously Controlled Chassis Concept) active chassis system, consisting of Comfort and Sport
modes, is available as an option.
NOTE: The V70 R has a standard FOUR-C system consisting of Comfort, Sport, and Advanced sport modes. The
buttons for controlling these driving modes are located in center instrument panel, above the ventilation system panel
vents, see the illustration in the right column. These buttons can be pressed at any time to change driving modes. An
indicator light in the selected button will come on to indicate the driving mode that is currently selected.
ProCarManuals.com

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. 101 Driving economy, Handling
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 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.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kick -down" to help improve fuel economy. Vehicles equipped with manual transmissions should use fifth gear at
highway speeds. At other times, choose the highest gear that still allows smooth acceleration.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
the recommended pressure according to the vehicle load. See "Tire pressure" section. Loads should be distributed so
that capacity weight or maximum permissible axle loads are not exceeded.

pg. 118 Wheels and tires
General information
Your vehicle is equipped with tires according to the vehicle's tire information placard on the B-pillar (the structural
member at the side of the vehicle, at the rear of the driver's door opening), or on the inside of the fuel filler door on
Canadian models.
The tires have good road holding characteristics and offer good handling on dry and wet surfaces. It should be noted
however that the tires have been developed to give these features on snow/ice-free surfaces.
Certain models are equipped with "all-season" tires, which provide a somewhat higher degree of road holding on
slippery surfaces than tires without the "all-season" rating. However, for optimum road holding on icy or snow-
covered roads, we recommend suitable winter tires on all four wheels.
When replacing tires, be sure that the new tires are the same size designation, type (radial) and preferably from the
same manufacturer, on all four wheels. Otherwise there is a risk of altering the car's roadholding and handling
characteristics.
ProCarManuals.com

Tires degrade over time, even when they are not being used, which can affect their reliability and roadholding
characteristics. Therefore, all tires older than 6 years (including the spare tire and winter tires) should be inspected by a
qualified technician, regardless of appearance or mileage. Heat caused by hot climates or frequent high loading
conditions can accelerate the aging process.
A tire's age can be determined by the DOT stamp on the sidewall (see the illustration above).
A tire with e.g., visible cracks or discoloration should be replaced immediately.
Improving tire economy:
• Maintain correct tire pressure. See the tire pressure table on page 122
.
• Drive smoothly: avoid fast starts, hard braking and tire screeching.
• Tire wear increases with speed.
• Correct front wheel alignment is very important.
• Unbalanced wheels impair tire economy and driving comfort.
• Tires must maintain the same direction of rotation throughout their lifetime.
• When replacing tires, the tires with the most tread should be mounted on the rear wheels to reduce the chance of
oversteer during hard braking.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
pg. 120 Wheels and tires
Tire inflation
Check tire inflation pressure regularly.
A table listing the recommended inflation pressure for your vehicle can be found on page 122
. Tire inflation pressure
placards are also located on the driver's side B-pillar (the structural member at the side of the vehicle, at the rear of the
driver's door opening), or on the inside of the fuel filler door on Canadian models. These placards indicate the
designation of the factory-mounted tires on your vehicle, as well as load limits and inflation pressure.

pg. 123 Wheels and tires
Tire Pressure Monitoring System (TPMS) - option on certain U.S. models only
The tire pressure monitoring system uses sensors mounted in the tire valves to check inflation pressure levels. When
the vehicle is moving at a speed of 20 mph (30 km/h) or faster, these sensors transmit inflation pressure data to a
receiver located in the vehicle.
USA - FCC ID: MRXTG315AM04
This device complies with part 15 of the FCC rules. Operation is subject to the following conditions: (1) This device
may not cause harmful interference, and (2) this device must accept any interference received, including interference
that may cause undesired operation.
WARNING!
The TPMS system uses a radio frequency of 315 MHz. Accessory electrical equipment using the same frequency
could interfere with TPMS and should not be installed in the vehicle. Please consult your Volvo retailer, a qualified
Volvo service technician, or the accessory equipment's supplier for further information.
When low inflation pressure is detected, TPMS will light up the tire pressure warning light (
) i (also referred to as a
telltale) in the instrument panel, and will display a message in the text window. The wording of this message is
determined by the degree of inflation pressure loss.
When the tire pressure monitoring system warning light is on, one or more of your tires is significantly under-inflated.
You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the
vehicle's tire information placard.
Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle's handling and stopping ability. Each tire,
including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified
in the vehicle placard and owner's manual.
NOTE: If a fault occurs in TPMS, the tire pressure warning light will flash for approximately 1 minute and TIRE
PRESS SYST SERVICE REQUIRED will be displayed.
ProCarManuals.com

Each tire, including the spare (if provided), should be checked monthly when cold and inflated to the inflation pressure
recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you should consult
the appropriate section of this owner's manual to determine the proper tire inflation pressure.) When the low tire
pressure telltale is illuminated, one or more of your tires is significantly underinflated. You should stop and check your
tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire causes
the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability. Your vehicle has also been equipped with a TPMS malfunction
telltale to indicate when the system is not operating properly. When the malfunction telltale is illuminated, the system
may not be able to detect or signal low tire pressure as intended. TPMS malfunctions may occur for a variety of
reasons, including the installation of incompatible replacement tires on the vehicle. Always check the TPMS
malfunction telltale after replacing one or more tires on your vehicle to ensure that the replacement tires are
compatible with the TPMS.
NOTE: TPMS indicates low tire pressure but does not replace normal tire maintenance. For information on correct tire
pressure, please refer to the table on page 122
, or consult your Volvo retailer.
Erasing warning messages
When a low tire pressure warning message has been displayed, and the tire pressure warning light has come on:
1. Use a tire pressure gauge to check the inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure (consult the tire pressure placard or the table on page 122
).
3. Drive the car for several minutes at a speed of 20 mph (30 km/h) or faster.
This will erase the warning text and the warning light will go out.
WARNING!
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of the vehicle.
(Contd. on following page)
pg. 124 Wheels and tires
Changing tires
Please note the following when changing or replacing the factory installed TPMS wheels/ tires on the vehicle:
Only the factory-mounted wheels are equipped with TPMS sensors in the valves.
If the vehicle is equipped with a temporary spare tire, this tire does not have a TPMS sensor.
If winter wheels without TPMS sensors are mounted on the vehicle, TIRE PRESS SYST SERVICE REQUIRED will
be displayed each time the vehicle is driven above 25 mph (40 km/h) for 10 minutes or more.
Once TPMS sensors are properly installed, the warning message should not reappear.
Volvo recommends that TPMS sensors be fitted on all wheels used on the vehicle. Volvo does not recommend
moving sensors back and forth between sets of wheels.
CAUTION!
When inflating tires with TPMS valves, press the pump's mouthpiece straight onto the valve to help avoid bending or
otherwise damaging the valve.

2. 65: The ratio of the tire's height to its width.
3. R: Radial tire.
4. 15: The diameter of the wheel rim (in inches).
5. 95: The tire's load index. In this example, a load index of 95 equals a maximum load of 1521 lbs (690 kg).
6. H: The tire's speed rating, or the maximum speed at which the tire is designed to be driven for extended periods of
time, carrying a permissible load for the vehicle, and with correct inflation pressure. For example, H indicates a speed
rating of 130 mph (210 km/h).
NOTE: This information may not appear on the tire because it is not required by law.
7. M+S or M/S = Mud and Snow, AT = All Terrain, AS = All Season
8. U.S. DOT Tire Identification Number (TIN): This begins with the letters "DOT" and indicates that the tire meets all
federal standards. The next two numbers or letters are the plant code where it was manufactured, the next two are the
tire size code and the last four numbers represent the week and year the tire was built. For example, the numbers 317
mean the 31st week of 1997. After 2000 the numbers go to four digits. For example, 2501 means the 25th week of
2001. The numbers in between are marketing codes used at the manufacturer's discretion. This information helps a tire
manufacturer identify a tire for safety recall purposes.
9. Tire Ply Composition and Material Used: Indicates the number of plies indicates or the number of layers of rubber-
coated fabric in the tire tread and sidewall. Tire manufacturers also must indicate the ply materials in the tire and the
sidewall, which include steel, nylon, polyester, and others.
10. Maximum Load: Indicates the maximum load in pounds and kilograms that can be carried by the tire. Refer to the
vehicle's tire information placard or the safety certification label, located on the B-Pillar or the driver's door or on the
inside of the fuel filler door on Canadian models, for the correct tire pressure for your vehicle.
11. Treadwear, Traction, and Temperature grades: See page 129
for more information.
12. Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This
limit is set by the tire manufacturer.
