7 Introduction
Volvo and the environment
Volvo is committed to the well being of its customers. As a natural part\
of this commitment, we care about the environment in which we
all live. Caring for the environment means an everyday involvement in re\
ducing our environmental impact. Volvo's environmental
activities are based on a holistic view, which means we consider the ove\
rall environmental impact of a product throughout its complete
life cycle. In this context, design, production, product use, and recycl\
ing are all important considerations. In production, Volvo has partly
or completely phased out several chemicals including CFCs, lead chromate\
s, asbestos, and cadmium; and reduced the number of
chemicals used in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-wa\
y catalytic converter with a Lambda sond, now called the heated
oxygen sensor, in 1976. The current version of this highly efficient sys\
tem reduces emissions of harmful substances (CO, HC, NOx) from
the exhaust pipe by approximately 95-99% 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 of all models as far back as the 1975 model 240. Advanced
electronic engine controls and cleaner fuels are bringing us closer to o\
ur goal. After Volvo vehicles and parts have fulfilled their use,
recycling is the next critical step in completing the life cycle. The me\
tal content is about 75% of the total weight of a vehicle, which makes
the vehicle among the most recycled industrial products. In order to hav\
e efficient and well controlled recycling, all Volvo variants have
printed dismantling manuals, indicating the weight and material of indiv\
idual components. For Volvo, all homogeneous plastic parts
weighing more than 3.4 oz. (100 grams) are marked with international s\
ymbols that indicate how the component is to be sorted for
recycling. In addition to continuous environmental refinement of convent\
ional 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:
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 in your Warranty and Service\
Records Information booklet.
l Drive at a constant speed whenever possible.
l See a trained and qualified Volvo service technician as soon as possible\
for inspection if the check engine (malfunction indicator) light
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 vehicle, please use genuine Volvo car care products. \
All Volvo car care products are formulated to be
environmentally friendly.

122 06 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.
Observe 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 engine \
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 Drive (D) position as often as possible and avo\
id using kickdown.
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 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.
Avoid overheating the engine
Do not drive at engine speeds above 4,500 rpm if you tow a trailer in hi\
lly areas. This could cause the
engine oil to overheat.

WARNING
Driving with the trunk open: Driving with the trunk open could lead to poisonous exhaust gases
entering the passenger compartment. If the trunk must be kept open for a\
ny reason, proceed as follows:
l Close the windows
l Set the ventilation system control to air flow to floor, windshield and \
side windows and the blower
control to its highest setting.
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 tendency to u\
ndersteer.
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle hand\
ling. Therefore,
123 06 Starting and driving
General information
check that the tires are inflated to the recommended pressure according \
to the vehicle load. See the "Tire
pressure" section. Loads should be distributed so that capacity weight o\
r maximum permissible axle loads
are not exceeded.
Driving through water
The vehicle can be driven through water up to a depth of approximately 9\
in. (25 cm), at a maximum
speed of 6 mph (10 km/h).
l Take particular care when driving through flowing water.
l Clean the electrical connections for trailer wiring after driving in mud\
or water
l When driving through water, maintain low speed and do not stop in the wa\
ter.
WARNING
After driving through water, press lightly on the brake pedal to ensure \
that the brakes are functioning
normally. Water or mud can make the brake linings slippery, resulting in\
delayed braking effect.

l Check condition of drive belts.
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 legally required in some states/provinc\
es.
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.
1 To prevent injury from contact with hot surfaces, do not inspect your v\
ehicle's transmission fluid yourself. Have
your vehicle's transmission fluid level inspected by a qualified Volvo s\
ervice technician.
125 06 Starting and driving
Fuel requirements
Octane rating
Volvo engines are designed to achieve rated horsepower, torque, and fuel\
economy performance using
premium 91 octane fuel.
Volvo recommends premium for best performance, but using 87 octane or ab\
ove will not affect engine
reliability.

General information
Your vehicle is equipped with tires according to the vehicle's tire info\
rmation 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 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 size desig\
nation, type (radial) and preferably
from the same manufacturer, on all four wheels. Otherwise there is a ris\
k of altering the car's roadholding
and handling characteristics.
Storing wheels and tires
When storing complete wheels (tires mounted on rims), they should be s\
uspended off the floor or placed
on their sides on the floor.
Tires not mounted on rims should be stored on their sides or standing up\
right, but should not be
suspended.
CAUTION
Tires should preferably be stored in a cool, dry, dark place, and should\
never be stored in close
proximity to solvents, gasoline, oils, etc.
WARNING
l The wheel and tire sizes for your are specified to meet stringent stabil\
ity and handling requirements.
Unapproved wheel/ tire size combinations can negatively affect your vehi\
cle's stability and handling.
Approved tire sizes are shown in the Tire inflation pressure tables on
pages 156 and 157.
l Any damage caused by installation of unapproved wheel/tire size combinat\
ions will not be covered
by your new vehicle warranty. Volvo assumes no responsibility for death,\
injury, or expenses that may
result from such installations.

You should replace the spare tire when you replace the other road tires \
due to the aging of the spare.
A tire's age can be determined by the DOT stamp on the sidewall (see th\
e illustration above).
A tire with e.g., visible cracks or discoloration should be replaced imm\
ediately.
Improving tire economy
l Maintain correct tire pressure. See the tire pressure tables on pages 156 and 157.
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 Tires must maintain the same direction of rotation throughout their life\
time.
l 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.
l Hitting curbs or potholes can damage the tires and/or wheels permanently\
.

Tire inflation
Check tire inflation pressure regularly.
Tables listing the recommended inflation pressure for your vehicle can b\
e found on
pages 156 and 157. A

tire inflation pressure placard is also located on the driver's side Bpi\
llar (the structural member at the side
of the vehicle, at the rear of the driver's door opening). This placard\
indicates the designation of the
factory-mounted tires on your vehicle, as well as load limits and inflat\
ion pressure.
NOTE
The placards shown indicate inflation pressure for the tires installed o\
n the car at the factory
only.
l Use a tire gauge to check the tire inflation pressure, including the spa\
re, at least once a month and
before long trips. You are strongly urged to buy a reliable tire pressur\
e gauge, as automatic service station
gauges may be inaccurate.
l Use the recommended cold inflation pressure for optimum tire performance\
and wear.
l Under-inflation or over-inflation may cause uneven treadwear patterns.
WARNING
l Under-inflation is the most common cause of tire failure and may result \
in severe tire cracking, tread
separation, or "blowout," with unexpected loss of vehicle control and in\
creased risk of injury.
l Under-inflated tires reduce the load carrying capacity of your vehicle. \
When weather temperature changes occur, tire inflation pressures also ch\
ange. A 10- degree temperature
drop causes a corresponding drop of 1 psi (7 kPa) in inflation pressur\
e. Check your tire pressures
frequently and adjust them to the proper pressure, which can be found on\
the vehicle's tire information
placard or certification label.
Checking tire pressure

2007 Volvo C70
Cold tires
Inflation pressure should be checked when the tires are cold.
The tires are considered to be cold when they have the same temperature \
as the surrounding
(ambient) air.
This temperature is normally reached after the car has been parked for a\
t least 3 hours.
155 07 Wheels and tires
Tire inflation
After driving a distance of approximately 1 mile (1.6 km), the tires a\
re considered to be hot. If you have
to drive farther than this distance to pump your tire(s), check and re\
cord the tire pressure first and add the
appropriate air pressure when you get to the pump.
If checking tire pressure when the tire is hot, never "bleed" or reduce \
air pressure. The tires are hot from
driving and it is normal for pressures to increase above recommended col\
d pressures. A hot tire at or
below recommended cold inflation pressure could be significantly under-i\
nflated.
To check inflation pressure
1. Remove the cap from the valve on one tire, then firmly press the tire\
gauge onto the valve.
2. Add air to reach the recommended air pressure
3. Replace the valve cap.
4. Repeat this procedure for each tire, including the spare.
5. Visually inspect the tires to make sure there are no nails or other o\
bjects embedded that could puncture
the tire and cause an air leak.
6. Check the sidewalls to make sure there are no gouges, cuts, bulges or\
other irregularities.
NOTE
l If you overfill the tire, release air by pushing on the metal stem in th\
e center of the valve. Then
recheck the pressure with your tire gauge.
l Some spare tires require higher inflation pressure than the other tires.\
Consult the tire inflation tables
on
pages 156 and 157 or see the inflation pressure placard.
