2003 VOLVO XC70
Volvo's environmental activities are based on a holistic view, which mea\
ns 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 chemica\
ls including freons, lead
chromates, naphtanates, asbestos, mercury and cadmium; and reduced the a\
mount 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 sy\
stem for all models as far back as
the M/Y 1975 240. Advanced electronic engine controls, refined purificat\
ion systems and cleaner fuels
are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the ne\
xt 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 c\
ontrolled recycling, many Volvo
variants have printed dismantling manuals, indicating the weight and mat\
erial 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 fo\
r recycling.
In addition to continuous environmental refinement of conventional gasol\
ine-powered internal
combustion engines, Volvo is actively looking at advanced technology alt\
ernative-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:
l Maintain proper air pressure in your tires. Tests have shown decreased f\
uel economy with improperly
inflated tires
l Follow the recommended maintenance schedule
l Drive at a constant speed
l See an authorized Volvo retailer as soon as possible for inspection if t\
he check engine (malfunction
indicator) lamp illuminates, or stays on after the vehicle has started \
l Properly dispose of any vehicle related waste such as used motor oil, us\
ed batteries, brake pads, etc.
l When cleaning your car, use Volvo's own car care products, all of which \
have systematically been
adapted to the environment

pattern, load-, speed-, traction-, temperature-, and treadwear rating. N\
ever 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). Tir\
es should be rotated front-to-
back/back-to-front only. Tires must maintain the same direction of rotat\
ion throughout their lifetime, and
should never be rotated from one side of the vehicle to the other.
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. 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 car 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 Do not exceed posted speed limits.
l Avoid carrying unnecessary items (extra load) in the car.
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 \
fuel consumption.
l Avoid using automatic transmission kickdown feature unless necessary.
l 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 spee\
ds, fuel consumption will be

lower with the air conditioning 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 othe\
rs are checked at the
standard Maintenance Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as o\
ften 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 high\
est gear that still allows smooth
acceleration.
Weight distribution affects handling
At the specified curb weight your car has a tendency to understeer, whic\
h 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 p\
roperties can alter with the
vehicle load. The heavier the load on the rear of the vehicle (e.g., he\
avily loaded (max. 220 lbs, 100 kg)
cargo area or when towing a trailer, the less the tendency to understeer\
.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. 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 permissib\
le axle loads are not
exceeded.

pg. 96 Points to remember
Cooling system
The risk for engine overheating is greatest, especially in hot weather, \
when:
l Towing a trailer up steep inclines for prolonged periods at wide open th\
rottle and low engine rpm.
l Stopping the engine suddenly after high speed driving (so-called "after\
-boiling" can occur).
l To avoid overheating, the following rules should be followed: Do not dri\
ve for prolonged periods at

pg. 101 Towing a trailer
When preparing for trailer towing, observe the following:
Volvo recommends the use of Volvo trailer hitches which are specially de\
signed for the car.
l Maximum trailer weight recommended by Volvo is:
Trailers without brakes: 1100 lbs (500 kg)
Trailers with brakes: 3300 lbs* (1,500 kg),
Observe the legal requirements of the state/province in which the vehicl\
es are registered.
l All Volvo models are equipped with energy-absorbing shock-mounted bumper\
s. Trailer hitch
installation should not interfere with the proper operation of this bump\
er system.
Trailer towing does not normally present any particular problems, but ta\
ke into consideration:
l Increase tire pressure to recommended full. See section "Wheels and tire\
s".
l When your car is new, avoid towing heavy trailers during the first 620 m\
iles (1000 km).
l Recommended hitch tongue load is:
Trailer weights below 2,650 lbs (1,200 kg) - 110 lbs (50 kg)
Trailer weights above 2,650 lbs (1,200 kg) - 165 lbs (75 kg)
l Maximum speed when towing a trailer: 50 mph (80 km/h).
l Engine and transmission are subject to increased loads. Therefore, engin\
e coolant temperature should
be closely watched when driving in hot climates or hilly terrain. Use a \
lower gear and turn off the air
conditioner if the temperature gauge needle enters the red range.
l If the automatic transmission begins to overheat, a message will be disp\
layed in the text window.
l Avoid overload and other abusive operation.
l Hauling a trailer affects handling, durability, and economy.
l It is necessary to balance trailer brakes with the towing vehicle brakes\
to provide a safe stop (check
and observe state/local regulations).
l Do not connect the trailer's brake system directly to the vehicle's brak\
e system.
l More frequent vehicle maintenance is required.
l Remove the ball and drawbar assembly when the hitch is not being used.
l Volvo recommends the use of synthetic engine oil when towing a trailer o\
ver long distances or in
mountainous areas.

pg. 105 Long distance trips
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer bef\
ore driving long distances. Your
retailer will also be able to supply you with bulbs, fuses, spark plugs \
and wiper blades for your use in the
event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check condition of accessory drive belts.
l Check transmission oil level*.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legal requirement in some countries.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
car's transmission fluid yourself.
Have your car's transmission fluid level inspected by a qualified Volvo \
service technician.

General information
Your vehicle is equipped with tires according to the tire information la\
bel 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 sect\
ion 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 som\
ewhat 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 dimensio\
ns, type (radial) and
preferably from the same manufacturer, on all four wheels. Do not use bi\
as 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), eith\
er 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 t\
read. When approx. 1/16" (1.6 mm)
is left on the tread, these strips become visible and indicate that the \
tire should be replaced.
Tires with less than 1/16" (1.6 mm) tread have very poor grip in rain \
or snow.
To improve tire economy:
l Maintain correct tire pressure. See the tire pressure label on the insid\
e of the fuel filler door.
l Drive smoothly: avoid fast starts, hard braking and tire screeching.
l Tire wear increases with speed.
l Correct front wheel alignment is very important.
l Unbalanced wheels impair tire economy and driving comfort.
l Volvo does not recommend rotating the tires. However, if tires are rotat\
ed, they must be kept on the
same side of the car so that they revolve in the same direction as befor\
e rotation.
l 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 par\
ked, the tires have a tendency to
distort slightly, forming flat spots. These flat spots can cause vibrati\
ons 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 dis\
appear.
CAUTION: The car must not be driven with wheels of different dimensions/specific\
ations or with a
spare tire other than the one that came with the car. The use of differe\
nt size wheels can seriously
damage your car's transmission or driveline.

Volvo recommends 195/65 R15 snow tires on non-turbo models. Turbo models\
should be equipped
with 205/55 R16 snow tires on all four wheels (215/65 R16 tires should \
be used on the XC70).
Winter tires wear more quickly on dry roads in warm weather. They should\
be removed when the winter
driving season has ended.
Studded tires should be run-in 300-600 miles (500-1000 km) during which the car shou\
ld be driven as
smoothly as possible to give the studs the opportunity to seat properly \
in the tires. The tires should have
the same rotational direction throughout their entire lifetime. In other\
words, if you wish to rotate the
wheels, make sure that the same wheels are always on the same side of th\
e car.
NOTE: Please consult state or provincial regulations restricting the use of st\
udded winter tires before
installing such tires.
* Where permitted.

Tire pressure label
Checking and correcting tire pressure
l Check the tire pressure regularly.
l The tire pressure should be corrected only when the tires are cold.
l With warm tires, correct only when the pressure is too low. The tire tem\
perature rises after driving
just a few miles.
