Refueling is done as follows.
1. Turn off the engine and open the fuel filler
door.
NOTE Refueling must be done within approximately
10 minutes of opening the fuel filler door.
After this time, the valve opened by pushing
the button will close and it will no longer be
possible to refuel without the pump's nozzle
switching off.
If the valve is closed before refueling is com-
plete - press the button again and wait until
the driver display shows the message
Fuel
tank Ready for refueling. 2. Select a fuel approved for use in the vehicle.
For more information on approved fuels, see
the section on "Gasoline".
3.

Insert the pump's nozzle into the fuel filler
pipe's opening. There are two flaps just
inside the fuel filler pipe and the pump's noz-
zle must push both of these flaps open
before fuel can be added. 4. Avoid overfilling the tank. Do not press the
handle on the filler nozzle again after it has
initially stopped pumping.
> The fuel tank is now filled.
NOTE An over-full tank may overflow in hot weather.
CAUTION
Avoid spilling gasoline during refueling. In
addition to causing damage to the environ-
ment, gasolines containing alcohol can cause
damage to painted surfaces, which may not
be covered under the New Vehicle Limited
Warranty.
Refueling from a fuel containerWhen filling from a fuel container, use the funnel
provided in a foam block under the floor hatch in
the cargo compartment.
1. Open the fuel filler door.
2. Insert the funnel into the fuel filler pipe's
opening. There are two flaps just inside the
fuel filler pipe and the tube section of the
funnel must push both of these flaps open
before fuel can be added.

Volvo recommends the use of detergent gaso-
line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-
tors and intake valves clean. Consistent use of
deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station operator.
NOTE
Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or after
refueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic con-
verter and must only use unleaded gasoline. US
and Canadian regulations require that pumps
delivering unleaded gasoline are labeled
"UNLEADED". Only the nozzles of these pumps
will fit in your vehicle's fuel filler inlet. It is unlaw-
ful to dispense leaded fuel into a vehicle labeled
"unleaded gasoline only". Leaded gasoline dam-
ages 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 methyl-
cyclopentadienyl manganese tricarbonyl
(MMT). If such fuels are used, your Emission
Control System performance may be affected,
and the Check Engine Light (malfunction
indicator light) located on your instrument
panel may light. If this occurs, please return
your vehicle to a trained and qualified Volvo
service technician for service.
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 permits the use of the following "oxygen-
ated" fuels. However, the specified octane ratings
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/ETBE: Fuels containing up to
15% MTBE/ETBE may be used.
MethanolDo 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.

.TOP TIER Detergent GasolineVolvo endorses the use of "TOP TIER Detergent
Gasoline" where available to help maintain
engine performance and reliability. TOP TIER
Detergent Gasoline meets a new standard jointly
established by leading automotive manufactures
to meet the needs of today's advanced engines.
Qualifying gasoline retailers (stations) will, in
most cases, identify their gasoline as having met
the "TOP TIER Detergent Gasoline" standards.
NOTE Information about TOP TIER Detergent Gaso-
line is available at www.toptiergas.com.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead or manga-
nese as a knock inhibitor, and do not use lead
additives. Besides damaging the exhaust emis-
sion control systems on your vehicle, 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 pre-
cautions. 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
• wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thickeners, or
other store-bought additives to your vehicle'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.
WARNING Never carry a cell phone that is switched on
while refueling your vehicle. If the phone rings,
this may cause a spark that could ignite gaso-
line fumes, resulting in fire and injury.

WARNINGCarbon 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 com-
partment is ventilated, and immediately return
the vehicle to a trained and qualified Volvo
service technician for correction.
Demanding drivingIn demanding driving conditions, e.g. when driving
in a hot climates, driving with a trailer or driving
for longer periods at higher altitudes (mountain
landscapes) than normal, it is recommended
switching to a higher octane fuel than AKI 91
6
or
changing gasoline brand to take full advantage of
your car's engine capacity and obtain the opti-
mum driving force.

Three-way catalytic converter
•
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving the
electrical, fuel or distributor ignition systems,
may cause unusually high three-way catalytic
converter temperatures. Do not continue to
operate your vehicle if you detect engine
misfire, noticeable loss of power or other
unusual operating conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
• Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
• Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
• Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components or location or removing components, and/or
repeated use of leaded fuel.NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen
content of the exhaust gases. Readings are fed
into a control module that continuously monitors
engine functions and controls fuel injection. The
ratio of fuel to air into the engine is continuously
adjusted for efficient combustion to help reduce
harmful emissions.

Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery)
has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make sure
that the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION Connect the jump cable carefully to prevent
short circuits with other components in the
engine compartment.
5. Fold back the cover over your vehicle's posi-
tive (+) jump start terminal (2).
6.

Clamp the other end of the red jumper cable
to your vehicle's positive (+) jump start termi-
nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) ground
point (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jump
starting. 10. Start the engine of the assisting vehicle and
let it run for a few minutes at a higher idling
speed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10
minutes of charging time and then try to start
the engine again.
NOTE When the engine is started under normal
conditions, the vehicle's electrical drive motor
is prioritized – the gasoline engine remains
off. This means that the electric motor has
"started" and the vehicle is ready to be driven
once the start knob has been turned clock-
wise. Start of the electric motor is indicated
by the indicator lights on the instrument panel
going out and its preselected theme illuminat-
ing.
CAUTION
Do not touch the connections between the
cable and the vehicle during the start attempt.
Risk of sparking. 12. Remove the jumper cables in the reverse
order ‒ first the black cables and then the
red cables.
Make sure that none of the clamps of the
black jumper cables come into contact with
either vehicle's positive (+) jump start termi-
nals or either of the red jumper cable's con-
nected clamps.

CAUTION•
Bumper-attached trailer hitches must not
be used on Volvos, nor should safety
chains be attached to the bumper.
• Trailer hitches attaching to the vehicle
rear axle must not be used.
• Never connect a trailer's hydraulic brake
system directly to the vehicle brake sys-
tem, nor a trailer's lighting system directly
to the vehicle lighting system. Consult
your nearest authorized Volvo retailer for
correct installation.
• When towing a trailer, the trailer's safety
chains or wire must be correctly fastened
to the attachment points provided in the
trailer hitch on the vehicle. The safety
chain or wire must never be fastened to
or wound around the towing ball.
NOTE The optional detachable trailer hitch may not
be available in all markets or on all models.
Consult your Volvo retailer.
NOTE
Extreme weather conditions, towing a trailer,
driving at high altitudes and fuel quality are
factors that significantly increase a vehicle's
fuel consumption.
Trailer weights
WARNING Please adhere to the recommendations provi-
ded for trailer weight. If the recommendations
are not followed, the vehicle and trailer may
be difficult to control during evasive maneu-
vers and braking.
NOTE
The specified maximum trailer weights are
those permitted by Volvo. National vehicle
regulations may set additional restrictions on
trailer weight and speed. The trailer hitches
may be certified for higher towing weights
than the vehicle is permitted to tow.
Self-leveling suspension*The vehicle's self-leveling system attempts to
keep the vehicle at a constant level, regardless of
load (up to the maximum permitted weight).
When the vehicle is stationary, the rear end of the
vehicle will be slightly lowered, which is normal.
Driving in hilly terrain or hot weatherIn certain conditions, there is a risk of overheat-
ing when driving with a trailer. If overheating of
the engine and drive system is detected, a warn-
ing symbol will illuminate in the instrument panel
along with a message.The automatic transmission selects the optimal
gear for the current load and engine speed.
