Unleaded fuel
Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations
require that pumps delivering unleaded gasoline be labeled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "unleaded gasoline only". Leaded
gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded
gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty
coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in
emission test failure for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Check Engine Lamp located on your instrument panel may light. If this occurs, please return your vehicle to
an authorized Volvo retailer for service.
Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell
exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the
vehicle to your retailer for correction.
Fuel Formulations
Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the
exhaust emission control systems on your car, lead has been strongly linked to certain forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you
live in an area where you must fill your own gas tank, take precautions. These may include:
standing upwind away from the filler nozzle while refueling
refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling
wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives
With the exception of gas line antifreeze during winter months, do not add solvents, thickeners, or other store -bought
additives to your car's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these
additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals.
ENGINE OIL
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearing in to each other. From the time the engine is new until
the first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 114
.
pg. 63 Fuel requirements, Refueling
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
ProCarManuals.com

The minimum octane requirement is AKI 87 (RON 91).
Gasoline containing alcohol and ethers
"Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or
local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in
which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check
with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated"
fuel.
Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be
met.
Alcohol — Ethanol
Fuels containing up to 10% ethanol by volume may be used.
Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
Refueling
The fuel tank is designed to hold approximately: 16 US gallons (60 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather.
Fuel filler door
The fuel filler door (on the left rear fender) is unlocked along with the car's central locking system.
Open fuel filler cap slowly during hot weather.
CAUTION:
· Do not refuel with the engine running *. 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 spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted surfaces, which
may not be covered under the New Vehicle Limited Warranty.
· Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
· Do not overfill the fuel tank. Overfilling could damage the emission control system.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Lamp may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or
approved fuel filler caps.

pg. 64 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 short trips. Short trips do 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.
· Maintain correct tire pressure. Check tire pressure regularly (check 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 thereby fuel consumption.
· Avoid using automatic transmission kickdown feature unless necessary.
· Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
· Utilizing the fuel consumption modes in the Trip Computer 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 : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/tailgate 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 blower control to its
highest setting.
pg. 65 Starting the engine
ProCarManuals.com

Starting and stopping
1. Fasten the seat belt.WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Make sure the gear selector is in the Park position.
3. Without touching the accelerator pedal, turn the ignition key to the starting position. Allow the starter to operate
for up to 5 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts. Depress the brake pedal and release the parking
brake.
4. To release the gear selector from the (P)ark position, the ignition key must be in position II and the brake pedal
must be depressed.
NOTE: Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in
the ( P)ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay which is especially noticeable when selecting R.
CAUTION :
The engine should be idling; never accelerate until after you feel the gear engage! Too rapid acceleration immediately
after selecting a gear will cause harsh engagement and premature transmission wear.
NOTE : Selecting P or N when idling at a standstill for prolonged periods of time will help prevent overheating of
transmission oil.
Ignition sleep mode
If the key is turned to "drive" position (see See page 26
) for several minutes without the engine running, the car's
starting system will power down to "sleep" mode. To start the car, momentarily turn the key back to the "locked"
position. Then start the car as you would normally do.
WARNING!
Always place the gear selector in Park and apply the parking brake before leaving the vehicle. Never leave the car
unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.
CAUTION:
Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast enough to
prevent engine damage.
Do not race the engine just prior to switching off!

pg. 66 Automatic transmission
P Park
The transmission must be in Park position to start the engine, and to allow removal of the key from the ignition when
you leave the car. The car should be stationary when you select P! In the position P the transmission is mechanically
locked. Always apply the parking brake when parking!
R Reverse
The car must be at a standstill before you select Reverse gear.
N Neutral position
The N position is the neutral position. The engine can be started, but no gear is selected. Apply the parking brake when
the car is stationary with the gear selector in position N.
D Driving position
D is the normal driving position. The gear se-lector automatically shifts up and down between the transmission gears,
based on the level of acceleration and the speed. The car should be stationary when you select D from position R.
4 Low gear position
Shifting up and down between the 1st, 2nd, 3rd, and 4th occurs automatically. Shifting up to Drive does not occur.
Position 4 can be used:
· for mountain driving
· for driving with trailer
· to increase the engine braking
3 Low gear position
Shifting up and down between the 1st, 2nd, and 3rd occurs automatically. The 4th and Drive gears will not be
engaged. Position 3 can be used:
· for mountain driving
· for driving with trailer
· to increase the engine braking
L Low gear position
Choose position L if you want to drive with the 1st or 2nd gear engaged. Position L gives the best possible engine
braking effect when, for example, mountain driving. Shifting up to 5th does not occur. Position 4 can be used:
· for mountain driving
· for driving with trailer
· to increase the engine braking
ProCarManuals.com

Downshifting protection
There is a built in protection in the transmission which prevents over revving in the engine when you select one of the
low gear positions.
Shift lock
In order to move the gear selector from P position to the other gear positions the key must be in driving position
(position II)and the brake pedal must be depressed. See page 99
how to move the gear selector manually in case of flat
battery.
pg. 67 Automatic transmission
W - Winter/Wet Weather
Use the W button to turn the Winter/Wet Weather function on or off. The Winter/Wet Weather function limits
downshifting during acceleration, helping to reduce wheel spin. Because downshifting is limited in W mode,
performance may seem sluggish and fuel economy may be reduced. W mode is recommended for acceleration from a
standstill on rain-slicked roads.
Automatic transmission -shift gate positions
The gear selector can be moved freely between N and D. Selections of other positions are obtained by depressing the
selector knob prior to moving the selector. Slightly depressing the selector knob allows selection of positions R, N, D,
4, 3 and L. Fully depressing the selector knob allows selection of position P. This is also necessary when initially
bringing the selector out of position P. Fully depressing the selector knob permits shifting freely between all positions.
Kick-down
Automatic shift to a lower gear (kick-down) is achieved by depressing the accelerator pedal fully and briskly. An
upshift will be achieved when approaching the top speed for a particular gear or by releasing the accelerator pedal
slightly. Kick -down can be used for maximum acceleration or when passing at highway speeds. Avoid using the kick-
down function during the break-in period (first 1,200 miles of vehicle operation).

Transmission Lamp
If the indicator lamp (see page 21 item 18
) begins to flash, this is an indication of a fault in the automatic transmission.
The Check Engine Lamp will also light up if a fault is detected. If the transmission does not shift properly, place the
gear selector in position L. Please contact your Volvo retailer if this occurs.

· Tar spots can be removed with kerosene or tar remover after the car has been washed.
· A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning improves
visibility considerably.
· Wash off the dirt from the underside (wheel housings fenders, etc.).
· In areas of high industrial fallout, more frequent washing is recommended.
CAUTION: During high pressure washing, the spray nozzle must never be closer to the vehicle than 13" (30 cm). Do
not spray into the locks.
· When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components or
toward the rear side of the engine.
· After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
Suitable detergents
Special car washing detergents should be used. A suitable mixture is about 2.5 fl. oz. (8.5 cl) of detergent to 2.6 US
gal. (10 liters) of warm water. After washing with a detergent the car should be well rinsed with clean water.
WARNING!
· When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
· Engine cleaning agents should not be used when the engine is warm. This may constitute a fire risk.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills. Bumpers: Wash
the bumpers with the same cleaning agent used on the rest of the car. Never clean the bumpers with gasoline or paint
thinner. Difficult spots can be removed with denatured alcohol. To avoid scratches, do not dry the bumpers with paper.
pg. 104 Automatic car washing, Polishing and waxing
Automatic washing simple and quick
Brushless car washes are recommended. An automatic wash is a simple and quick way to clean your car, but it is
worth remembering that it may not be as thorough as when you yourself go over the car with sponge and water.
Keeping the underbody clean is most important, especially in the winter. Some automatic washers do not have
facilities for washing the underbody.
Before driving into an automatic wash, make sure that side view mirrors, auxiliary lamps, etc., are secure, otherwise
there is risk of the machine dislodging them. You should also lower the antenna (sedans).
We do NOT recommend washing your car in an automatic wash during the first six months because the paint
will not have hardened sufficiently.
Polishing and waxing
Normally, polishing is not required during the first year after delivery, however, waxing is recommended.
