2001 VOLVO S80 ECO mode

Before you operate your car for the first time, please familiarize yourself with the BREAK-IN information on
page 62. You should also be familiar with the information in the first three chapters of this manual.
Information contained in the balance of the manual is extremely useful and should be read after operating the
vehicle for the first time.
The manual is structured so that it can be used for reference. For this reason, it should be kept in the car for
ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and exhaust
emission requirements. In some cases it may be difficult or impossible to comply with these requirements.
Modifications to the emission control system(s) may render your Volvo not certifiable for legal operation in the
U.S., Canada and other countries.
All information, illustrations and specifications contained in this manual are based on the latest product
information available at the time of publication. Please note that some vehicles may be equipped differently,
depending on special legal requirments and that optional equipment described in this manual may not be
available in all markets.
Volvo reserves the right to make model changes at any time, or to change specifications or design, without
notice and without incurring obligation.
Volvo and the environment
Volvo is committed to the well being of our 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.
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 system for all models as far back as the M/Y 1975 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.

N (Neutral)
Neutral - no gear engaged. Use the parking brake.
D (Drive)
D is the normal driving position and should be used as often as possible to help improve fuel economy. The car should
not be moving when shifting from R to the D position.
Kickdown
Automatic shift to a lower gear (kickdown) is achieved by depressing the accelerator pedal fully and briskly. An
upshift will occur when approaching the top speed for a particular gear or by releasing the accelerator pedal slightly.
Kickdown can be used for maximum acceleration or when passing at highway speeds. Kickdown does not function
when the transmission is in the manual shift (geartronic) mode (see next page).
Shift gate positions
Automatic transmission - adaptive system
The automatic transmission is controlled by an adaptive control system that constantly monitors the way in which the
transmission functions. It senses and adapts each gear shift for optimal performance. The system also monitors your
particular driving style and adapts gear shifting accordingly.
Automatic transmission - shift gate positions
You can move the gear selector freely between the (MAN)ual and (D)rive positions while driving.
Depress the selector knob on the front side of the gear selector to move between the R, N, D and P positions.
Please see the following page for information on using the Geartronic manual shift mode.
pg. 70 Automatic transmission (Geartronic)
Manual shifting - Geartronic
You can move the gear selector freely between the (MAN) ual and (D)rive positions while driving. Gears 2, 3, and 4
have a "lock -up" function which reduces engine speed and helps save fuel.
The currently selected gear will be displayed in the instrument panel (see page 23
).
· To access the (MAN)ual shifting position from (D)rive, pull the gear selector back slightly from D and move it to the

left to MAN.
· To return to the (D)rive position from MAN, move the gear selector to the right and push it forward to the (D)rive
position.
While driving
If you select the (MAN)ual position while driving, the gear that was being used in the (D)rive position will also
initially be selected in (MAN)ual position.
· Move the gear selector forward (toward "+") to shift to a higher gear or rearward (toward "-") to shift to a lower gear.
· If you hold the gear selector toward "-", the transmission will downshift, one gear at a time, and will utilize the
braking power of the engine. If the current speed is too high for using a lower gear, the downshift will not occur until
the speed has decreased enough to allow the lower gear to be used.
· If you slow down to a very low speed, the transmission will automatically shift down.
· When starting in the (MAN)ual position, 3rd gear is the highest gear that may be selected.
NOTE: Kickdown (see previous page) does not function when the transmission is in the manual shift (geartronic)
mode.
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 (see illustration).
· An LED in the button will light up to indicate that W is engaged and this will also be displayed in the instrument
panel (see page 23
).
· This mode may be selected for starting/moving off on slippery roads.
pg. 71 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. Observe the following rules:
· 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.
· Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
· Drive carefully and avoid rapid acceleration and hard braking.
· Do not exceed posted speed limits.
· Avoid carrying unnecessary items (extra load) in the car.
· Maintan correct tire pressure. Check tire pressure regularly (when tires are cold).
· Remove snow tires when threat of snow or ice has ended.
ProCarManuals.com

· Note that roof racks, ski racks, etc., increase air resistance and also fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· However, at higher 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 which decrease gas mileage are:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· 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 Service intervals.
NOTE: Vehicles equipped with automatic transmissions should use (D)rive as often as possible and avoid using
"kickdown" to help improve fuel economy.
Cooling system
The risk for engine overheating is greatest, especially in hot weather, when:
· Towing a trailer up steep inclines for prolonged periods at wide open throttle and low engine rpm.
· Stopping the engine suddenly after high speed driving (so-called "after-boiling" can occur).
· To avoid overheating, the following rules should be followed: Do not drive for prolonged periods at engine speeds
above 4500 rpm if you are towing a trailer in hilly terrain.
· Reduce speed when towing a trailer up long, steep inclines. The risk of overheat -ing can be reduced by switching off
the air conditioning system for a short time.
· Do not let the engine idle unnecessarily for prolonged periods.
· Do not mount auxiliary lamps in front of the grill. When the risk of overheating is imminent, or in the event of
overheating (the temperature gauge goes repeatedly into, or stays continual-ly in, the red section), the following
precau-tions should be taken:
· Switch off the air conditioning system.
· Pull off the road, away from traffic, stop the car and put the gear selector into Park. Do not stop the engine!
· Switch the heater to full (maximum) position. Increase the engine speed to approx. 2000 rpm (twice idling speed)
until the temperature begins to drop.
· If the warning light in the center of the instrument panel is red, and the message "Coolant level lo stop engine" is
displayed, switch off the engine as soon as possible.
WARNING!
Do not remove coolant expansion tank cap. The coolant will be extremely hot.
If necessary, see See page 110
for information on checking and topping-up the coolant level.

General information
Your vehicle is equipped with tires according to the tire information label 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 section 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/icefree surfaces. Certain models are
equipped with "all-season" tires, which provide a somewhat 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 designation, type (radial) and preferably from the same manufacturer, on all four wheels. Otherwise there is a risk
of altering the car's roadholding and handling characteristics.
NOTE: When storing wheel/tire assemblies (e.g. winter tires and wheels), either 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

Checking and correcting tire pressure
· Check the tire pressure regularly.
· The tire pressure should be corrected only when the tires are cold.
· With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label located on the inside of the fuel filler door. This label lists both tire and vehicle design limits.
Do not load your car beyond the load limits indicated.
Temporary Spare (certain models)
The spare tire in your car is called a "Temporary Spare". It has the following designation: T125/80 R17.
Recommended tire pressure (see decal on fuel filler door) should be maintained irrespective of which position on the
car the Temporary Spare tire is used on.
In the event of damage to this tire, a new one can be purchased from your Volvo retailer.WARNING!
Current legislation prohibits the use of the "Temporary Spare" tire other than as a temporary replacement for a
punctured tire. In other words, it must be replaced as soon as possible by a standard tire. Road holding and handling
may be affected with the "Temporary Spare" in use. Do not exceed 50 mph (80 km/h). Do not drive farther than 50
miles (80 km) on a temporary spare tire.
CAUTION:
The car must not be driven with wheels of different dimensions or with a spare tire other than the one that came with
the car. The use of different size wheels can seriously damage your car's transmission.
NOTE: Certain models may be equipped with a full-size spare tire. When used, it should be inflated to the same
pressure as the tire it is replacing.
