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.

17 01 Safety
Supplemental Restraint System
Supplemental Restraint System (SRS)
As an enhancement to the three-point seat belts, your Volvo is equipped \
with a Supplemental Restraint
System (SRS). Volvo's SRS consists of seat belt tensioners, front airb\
ags, side impact airbags, the
occupant weight sensor, and inflatable curtains. All of these systems ar\
e monitored by the SRS control
module. An SRS warning light in the instrument panel (see the illustrat\
ion above) illuminates when the
ignition key is turned to position I, II, or III, and will normally go o\
ut after approximately 7 seconds if no
faults are detected in the system.
Where applicable, a text message will also be displayed when the SRS war\
ning light illuminates. If this
warning symbol is not functioning properly, the general warning symbol
illuminates and either SRS
AIRBAG SERVICE URGENT or SRS AIRBAG SERVICE REQUIRED will be displayed.
WARNING
l If the SRS warning light stays on after the engine has started or if it \
illuminates while you are driving,
have the vehicle inspected by a trained and qualified Volvo service tech\
nician as soon as possible.
l Never try to repair any component or part of the SRS yourself. Any inter\
ference in the system could
cause malfunction and serious injury. All work on these systems should b\
e performed by a trained and
qualified Volvo service technician.

1. Malfunction indicator light

As you drive, a computer called On-Board Diagnostics II (OBDII) monito\
rs 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 trained and qualifi\
ed Volvo service technician as soon as
possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in y\
our car's behavior.
Even so, an uncorrected condition could hurt fuel economy, emission cont\
rols, and drivability. Extended driving
without correcting the cause could even damage other components in your \
car.
NOTE
Canadian models are equipped with the second
symbol.
2. 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).

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.

2007 Volvo C70
CAUTION
l Engine damage will occur if water is drawn into the air cleaner.
l If the vehicle is driven through water deeper than 9 in (25 cm), water\
may enter the differential and
the transmission. This reduces the oil's lubricating capacity and may sh\
orten the service life of these
components.
l Do not allow the vehicle to stand in water up to the door sills longer t\
han absolutely necessary. This
could result in electrical malfunctions.
l If the engine has been stopped while the car is in water, do not attempt\
to restart the engine. Have the
car towed out of the water.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, t\
he following advice is worth
noting:
l Make sure that the engine coolant contains 50 percent antifreeze. Any ot\
her mixture will reduce freeze
protection. This gives protection against freezing down to - 31°F (-\
35°C). See section "Coolant". The use
of "recycled" antifreeze is not approved by Volvo. Different types of an\
tifreeze must not be mixed.
l Volvo recommends using only genuine Volvo antifreeze in your vehicle's r\
adiator. Your Volvo retailer
stocks plenty of Volvo engine coolant to help protect your vehicle durin\
g cold weather.
l Try to keep the fuel tank well filled - this prevents the formation of c\
ondensation in the tank. In
addition, in extremely cold weather conditions it is worthwhile to add f\
uel line de-icer before refueling.
l The viscosity of the engine oil is important. Oil with low viscosity (t\
hinner oil) improves cold-weather
starting as well as decreasing fuel consumption while the engine is warm\
ing up. For winter use, 5W-30
oil, particularly the synthetic type
1, is recommended. Be sure to use good quality oil but do not use cold-
weather oil for hard driving or in warm weather. See
page 239 for more information.
l The load placed on the battery is greater during the winter since the wi\
ndshield wipers, lighting, etc. are
used more often. Moreover, the capacity of the battery decreases as the \
temperature drops. In very cold
weather, a poorly charged battery can freeze and be damaged. It is there\
fore advisable to check the state
of
1Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at owner request and
at additional charge. Please consult your Volvo retailer.

General information
charge more frequently and spray an antirust oil on the battery posts.
l Volvo recommends the use of snow tires on all four wheels for winter dri\
ving - see the chapter "Wheels
and tires."

2007 Volvo C70
l To prevent the washer fluid reservoir from freezing, add washer solvents\
containing antifreeze (see
page 193 for the location of the washer fluid reservoir). This is important sin\
ce dirt is often splashed on
the windshield during winter driving, requiring the frequent use of the \
washers and wipers. Volvo Washer
Solvent should be diluted as follows: Down to 14° F (-10° C): 1 \
part washer solvent and 4 parts water
Down to 5° F (-15° C): 1 part washer solvent and 3 parts water D\
own to 0° F (- 18° C): 1 part washer
solvent and 2 parts water Down to -18° F (-28° C): 1 part washer\
solvent and 1 part water.
l Use Volvo Teflon Lock Spray in the locks.
NOTE
Avoid using de-icing sprays as they can cause damage to the
locks.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
l When the engine is not running, avoid turning the ignition key to positi\
on II. Many electrical systems
(the audio system, the optional navigation system, power windows, etc)\
will function with the ignition
key in position I. This position reduces drain on the battery.
l Please keep in mind that using systems, accessories, etc that consume a \
great deal of current when the
engine is not running could result in the battery being completely drain\
ed.
l The optional 12 volt socket in the cargo area provides electrical curren\
t even with the ignition switched
off, which drains the battery.
NOTE
l If the ignition is switched on, a warning message will be displayed in t\
he text window in the
instrument panel when the battery charge is low.
l An energy conserving function designed into the vehicle's electrical sys\
tem will switch off certain
functions or reduce the load on the battery by, e.g., reducing the audio\
system's volume.
Before a long distance trip
It is always worthwhile to have your vehicle checked at a Volvo retailer\
before driving long distances.
Your retailer will also be able to supply you with bulbs, fuses, spark p\
lugs 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 Have the transmission oil level checked1.
