Introduction
WARNING!
CALIFORNIA proposition 65
Engine exhaust, some of its constituents, and certain vehicle components contain or emit chemicals known to the
state of California to cause cancer, and birth defects or other reproductive harm. In addition, certain fluids contained
in vehicles and certain products of component wear contain or emit chemicals known to the State of California to
cause cancer, and birth defects or other reproductive harm.
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 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.
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% 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 of all models as far back as the 1975 model 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 in your Warranty and Service Records Information booklet.

Drive carefully and avoid rapid acceleration and hard braking.
Use the transmission's (D)rive position as often as possible and avoid using kickdown.
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 consumption.
At highway 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 intervals.
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.
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 any reason, proceed as follows:
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
pg. 99 General information
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 distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
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 by Volvo. 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.
ProCarManuals.com

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 decreasing fuel consumption while the engine is warming 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 187
for more information.
The load placed on the battery is greater during the winter since the windshield 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 therefore advisable to check the state of charge more frequently and spray an
anti-rust oil on the battery posts.
Volvo recommends the use of snow tires on all four wheels for winter driving - see the chapter "Wheels and tires."
To prevent the washer fluid reservoir from freezing, add washer solvents containing antifreeze (see page 148 for the
location of the washer fluid reservoir). This is important since 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, Down 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.
Use Volvo Teflon Lock Spray in the locks.
NOTE: Avoid using de -icing sprays as they can cause damage to the locks.
1. Synthetic 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.
Conserving electrical current
Keep the following in mind to help minimize battery drain:
When the engine is not running, avoid turning the ignition key to position II. Many electrical systems (the audio
pg. 100 General information
system, the optional navigation system, power windows, etc) will function with the ignition key in position I. This
position reduces drain on the battery.
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 drained.
The optional 12 volt socket in the trunk provides electrical current even with the ignition switched off, which drains
the battery.
NOTE: If the ignition is switched on, a warning message will be displayed in the text window in the instrument panel
when the battery charge is low.
An energy conserving function designed into the vehicle's electrical system will switch off certain functions or reduce
the load on the battery by, e.g., reducing the audio system's volume.
W Winter/Wet driving mode- enhanced vehicle traction
Mode W will only function 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.
An LED in the button will light up to indicate that W is engaged.
This mode may be selected for starting/moving off on slippery roads.
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 plugs and wiper blades for your use in the event that problems
