Volvo and the environment
Volvo is committed to the well being of its cus-
tomers. 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 reducing our environ-
mental 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 CFCs,
lead chromates, 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-way catalytic converter with
a Lambda sond, now called the heated 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 – 99% and
the search to eliminate the remaining emis-
sions continues. Volvo is the only automobile
manufacturer to offer CFC-free retrofit kits for
the air conditioning system of all models as far
back as the 1975 model 240. Advanced elec-
tronic engine controls and cleaner fuels are
bringing us closer to our goal. In addition tocontinuous environmental refinement of con-
ventional gasoline-powered internal combus-
tion engines, Volvo is actively looking at
advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our part-
ner 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 econ-
omy with improperly inflated tires.
•Follow the recommended maintenance
schedule in your Warranty and Service
Records Information booklet.
•Drive at a constant speed whenever pos-
sible.
•See a trained and qualified Volvo service
technician as soon as possible for inspec-
tion if the check engine (malfunction indi-
cator) light illuminates, or stays on after the
vehicle has started.
•Properly dispose of any vehicle-related
waste such as used motor oil, used batter-
ies, brake pads, etc.
•When cleaning your vehicle, please use
genuine Volvo car care products. All Volvo
car care products are formulated to be
environmentally friendly.
RecyclingAs part of Volvo’s commitment to the environ-
ment, it is essential for the vehicle to be recy-
cled in an environmentally sound way. Almost
the entire vehicle can be recycled and for that
reason, the vehicle’s final owner is requested
to contact a Volvo retailer for information about
approved and certified recycling facilities.

1. Malfunction indicator light
As you drive, a computer called
On-Board Diagnostics II (OBDII)
monitors your car's engine, trans-
mission, 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
qualified Volvo service technician as soon as
possible.
A CHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a change
in your car's behavior. Even so, an uncorrected
condition could hurt fuel economy, emission
controls, and drivability. Extended driving with-
out 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).
The vehicle should be driven to a
trained and qualified Volvo service
technician for inspection, see
page 154 for additional informa-
tion.
NOTE
Canadian models are equipped with the
second symbol.
3. Rear fog lightThis symbol indicates that the rear
fog light (located in the driver's
side taillight cluster) is on.
4. Stability system STC or DSTCThis indicator symbol flashes when
the STC (Stability and Traction
control system) or the DSTC
(Dynamic Stability and Traction
control system) is actively working
to stabilize the car, see page 158 for more
detailed information.
5. Tire Pressure Monitoring SystemThis system monitors inflation
pressure in the tires. See page
200 for more information.
6. Fuel level warning lightWhen this light comes on, the vehi-
cle should be refueled as soon as
possible.

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 tem-
perature 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 vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's Drive (D) position
as often as possible and avoid using kick-
down.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•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 con-
sumption.
•At highway driving speeds, fuel consump-
tion 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
intervals.
WARNING
Driving with the trunk open: Driving with
the trunk open could lead to poisonous
exhaust gases entering the passenger com-
partment. If the trunk must be kept open for
any reason, proceed as follows:
1. Close the windows.
2. Set the ventilation system control to air
flow to floor, windshield and side win-
dows and the blower control to its high-
est 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 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 in the cargo area, the less
the tendency to understeer.

141 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 the
"Tire pressure" section. Loads should be dis-
tributed so that capacity weight or 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).
•Take particular care when driving through
flowing water.
•Clean the electrical connections for trailer
wiring after driving in mud or water
•When driving through water, maintain low
speed and do not stop in the water.
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.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 9 in. (25 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•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, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other 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 byVolvo. Different types of antifreeze must
not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
Your Volvo retailer stocks plenty of Volvo
engine coolant to help protect your vehicle
during cold weather.
•Try to keep the fuel tank well filled – this
prevents the formation of condensation in
the tank. In addition, in extremely cold
weather conditions it is worthwhile to add
fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type
1, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 274 for more
information.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
1Synthetic oil is not used when the oil is changed at the normal maintenance intervals except at owner request and at additional charge. Please consult your Volvo retailer.

•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by your
Volvo retailer only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with your Volvo retailer if you
intend to drive in countries where it may be
difficult to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.

Fuel requirements
06
146
You can also keep the vehicle 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.
Refueling
The fuel tank is designed to accommodate
possible expansion of the fuel in hot weather,
see page 273 for fuel tank volume. Be aware
that the "usable" tank capacity will be some-
what 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 advis-
able to refuel as soon as possible when the
needle nears the red zone, or when the fuel
warning light comes on.
CAUTION
•Do not refuel with the engine running2.
Turn the ignition off or to position I. If the
ignition is on, an incorrect reading could
occur in the fuel gauge
•After refueling, close the fuel filler cap
by turning it clockwise until it clicks into
place.
•Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much fuel
in the tank in hot weather conditions can
cause the fuel to overflow. Overfilling
could also cause damage to the emis-
sion control systems.
•Avoid spilling gasoline during refueling.
In addition to causing damage to the
environment, gasolines containing
alcohol can cause damage to painted
surfaces, which may not be covered
under the New Vehicle Limited War-
ranty.
•Do not use gasolines containing meth-
anol (methyl alcohol, wood alcohol).
This practice can result in vehicle per-
formance deterioration and can dam-
age critical parts in the fuel system.
Such damage may not be covered
under the New Vehicle Limited War-
ranty.
2If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (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.

161
WARNING
•Never allow a vehicle to be towed with-
out a driver behind the wheel of the dis-
abled vehicle.
•Never remove the key from the ignition
while the vehicle is moving. The steering
wheel could lock, making it impossible
to steer the vehicle.
•When the engine is not running, steering
resistance and the effort needed to
apply the brakes will be great.
•Never attempt to tow a vehicle with a
dead battery at night.
CAUTION
•Check with state and local authorities
before attempting this type of towing,
as vehicles being towed are subject to
regulations regarding maximum towing
speed, length and type of towing
device, lighting, marker flags, etc.
•Never attempt to push- or tow-start a
vehicle with a dead battery. This would
inject unburned fuel into the three-way
catalytic converter(s), causing over-
heating, backfiring, and damage, see
page 162 for instructions on jump star-
ting the vehicle.
Towing vehicles with front wheel drive
Volvo recommends the use of flat bed equip-
ment for towing vehicles with front wheel drive.
If wheel lift equipment must be used, please
use extreme caution to help avoid damage to
the vehicle.
In this case, the vehicle should be towed with
the rear wheels on the ground if at all possible.
If it is absolutely necessary to tow the vehicle
with the front wheels on the ground, please
refer to the towing information on the previous
page.
•Sling-type equipment applied at the front
will damage radiator and air conditioning
lines.
•It is equally important not to use sling-type
equipment at the rear or apply lifting equip-
ment inside the rear wheels; serious dam-
age to the rear axle may result.
•If the vehicle is being towed on a flat bed
truck, the towing eyelets must not be used
to secure the vehicle on the flat bed. Con-
sult the tow truck operator.
WARNING
•Remember that the power brakes and
power steering will not function when
engine is not running. The braking and
steering systems will function but con-
siderably higher pressure will be
required on the brake pedal and greater
steering effort must be exerted.
•The towing eyelets must not be used for
pulling the vehicle out of a ditch or for
any similar purpose involving severe
strain. Do not use the towing eyelets to
pull the vehicle up onto a flat bed tow
truck.
