environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact.
Volvo's environmental activities are based on a holistic view, which means we consider the overall environmental
impact of a product throughout its complete life cycle. In this context, design, production, product use, and recycling
are all important considerations.
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
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
Prem-Air®
On the surface of the radiator in the engine compartment, there is a special coating called Prem-Air®. Prem-Air®
works as a catalytic converter, converting most of the ozone passing through the radiator into oxygen, thereby reducing
harmful ground-level ozone.

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. 86 Refueling
Refueling
The fuel tank holds approximately 18.5 US gals (70 liters) or 19 US gals (72 liters) on models equipped with All
Wheel Drive, 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 34) 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.
NOTE: During a transitional period, a small number of service stations may still have fuel nozzles that are not
compatible with the fuel filler neck on cars equipped with the evaporative control system. Please refer to page 130

If you hold the gear selector toward "-", the transmission will downshift, one gear at a time, and will utilize the
braking power of the engine. If the current speed is too high for using a lower gear, the downshift will not occur until
the speed has decreased enough to allow the lower gear to be used.
If you slow down to a very low speed, the transmission will automatically shift down.
When starting in the (MAN)ual position, 3rd gear is the highest gear that may be selected.
NOTE: Kickdown (see previous page) does not function when the transmission is in the manual shift (geartronic)
mode. The gear selector must be in the D (Drive) position.
W Winter/Wet driving mode - enhanced vehicle traction
Mode W will function only if the gear selector is in the (D)rive position.
Press the button at the base of the gear selector to engage/disengage this driving mode (see illustration).
An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument
panel (see page 27
).
This mode may be selected for starting/moving off on slippery roads.
pg. 94 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
pressure label located inside the fuel filler door.
Tire Rotation
Volvo recommends rotating the tires every 7,500 miles (12,000 km). Tires should be rotated front -to-back/back-to-
front only. Tires must maintain the same direction of rotation throughout their lifetime, and should never be rotated
from one side of the vehicle to the other.
ProCarManuals.com

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, in accordance with "Tire Rotation" above. 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. 95 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 conditioner's 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.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load on the rear of
the vehicle (e.g., heavily loaded (max. 220 lbs, 100 kg) cargo area or when towing a trailer, the less the tendency to
understeer.

pg. 108 Wheels and tires
General information
Your vehicle is equipped with tires according to the tire information label on the inside of the fuel filler door.
The following is an example of a tire designation code: 225/55 R16
225 = tire width in mm.
55 = tire profile. This is the relationship (in percent) between the section height and width of the tire.
R = radial tires.
16 = diameter in inches.
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
dimensions, type (radial) and preferably from the same manufacturer, on all four wheels. Do not use bias ply tires.
Otherwise there is a risk of altering the car's roadholding and handling characteristics.
NOTE: When storing wheel/tire assemblies (e.g. snow tires and wheels), either stand the assemblies upright, or
suspend them off the ground. Laying wheel/tire assemblies on their sides for prolonged periods can cause wheel and/or
tire damage.
Wear indicator
The tires have wear indicator strips running across or parallel to the tread. When approx. 1/16" (1.6 mm) is left on the
tread, these strips become visible and indicate that the tire should be replaced.
ProCarManuals.com

Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain or snow.
To improve tire economy:
Maintain correct tire pressure. See the tire pressure label on the inside of the fuel filler door.
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.
Volvo does not recommend rotating the tires. However, if tires are rotated, they must be kept on the same side of the
car so that they revolve in the same direction as before rotation.
Hitting curbs or potholes can damage the tires and/or wheels permanently.
Flat spots
All tires become warm during use. After cooling, when the vehicle is parked, the tires have a tendency to distort
slightly, forming flat spots. These flat spots can cause vibrations similar to the vibrations caused by unbalanced wheels.
They do, however, disappear when the tire warms up. The degree to which flat spots form depends on the type of cord
used in the tire. Remember that, in cold weather, it takes longer for the tire to warm up and consequently longer for the
flat spot to disappear.
CAUTION: The car must not be driven with wheels of different dimensions/specifications or with a spare tire other
than the one that came with the car. The use of different size wheels can seriously damage your car's transmission or
driveline.
pg. 109 Wheels and tires
Snow chains
Snow chains can be used on your Volvo with the following restrictions:
Snow chains should be installed on front wheels only. Use only Volvo approved snow chains.
Special snow chains must be mounted on 215/55 R16. Consult your Volvo retailer.
If accessory, aftermarket or "custom" tires and wheels are installed and are of a size different than the original tires
and wheels, chains in some cases CANNOT be used. Sufficient clearances between chains and brakes, suspension and
body components must be maintained. Snow chains cannot be used on 17" wheels.
Some strap -on type chains will interfere with brake components and therefore CANNOT be used.
All Wheel Drive models: Snow chains should only be installed on the front wheels. Only chains adapted for AWD
models should be used.
Consult your Volvo retailer for additional snow chain information.
CAUTION:
Check local regulations regarding the use of snow chains before installing.
Always follow the chain manufacturer's installation instructions carefully. Install chains as tightly as possible and
retighten periodically.
Never exceed the chain manufacturer's specified maximum speed limit. In no case should you exceed 31 mph (50
km/h).
Avoid bumps, holes or sharp turns when driving with snow chains.
Vehicle handling can be adversely affected when driving with chains. Avoid fast maneuvering and hard braking.

Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label located on the inside of the fuel filler door*. This label also lists vehicle load limits. Do not load
your car beyond the indicated limits.WARNING!
Improperly inflated tires will reduce tire life, adversely affect vehicle handling and can possibly lead to failure
resulting in loss of vehicle control without prior warning.
Temporary Spare
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/80 R17 (T135/90 R17
on the XC70).
At the recommended tire pressure shown on the inside of the fuel filler door, the tire may be used as a temporary
replacement for a front or rear tire.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. It must be replaced as soon as possible by a standard tire. Road holding and handling may be affected
with the "Temporary Spare" in use. Do not exceed 50 mph (80 km/h). Do not drive farther than 50 miles (80 km) on
a temporary spare tire.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
NOTE: Certain models may be equipped with a full-size spare tire. When used, it should be inflated to the same
pressure as the tire it is replacing.
*Please note that the tire information label indicates pressure for both comfort and fuel economy.
pg. 111 Wheels and tires
Uniform tire quality grading
ALL PASSENGER CAR TIRES MUST CONFORM TO FEDERAL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
