STARTING AND DRIVING
462Driving through standing water
Driving the vehicle through a deep pool of stand-
ing water on a water-covered roadway is called
fording. This must be done with great caution. To prevent damage to the vehicle when driving
through water (e.g. on flooded roads):
• Do not drive in water higher than the floor of
the vehicle. If possible, check the depth of
the water at its deepest point before driving
through it. Be particularly careful when driv-
ing through flowing water.
• Always select the Off Road drive mode
before driving in water to ensure the gasoline
engine is running.
• Do not drive faster than walking speed.
• Do not stop the vehicle in the water. Drive
carefully forward or back the vehicle out of
the water.
• Remember that waves created by passing
vehicles could cause the water level to rise
above the vehicle's floor level.
• Avoid driving through salt water to help avoid
the risk of corrosion.
CAUTION Parts of the vehicle (e.g. engine, transmission,
driveline, electrical components, etc.) can be
damaged if the vehicle is driven through water
higher than its floor level. Damage to any
components caused by flooding, vapor lock or
insufficient oil is not covered under warranty.
If the engine stalls while the vehicle is in
water, do not attempt to restart it. Have the
vehicle towed on the bed of a tow truck to a
workshop - an authorized Volvo workshop is
recommended.
When you have passed the water, press lightly on
the brake pedal and check that the brakes are
functioning properly. Water, mud, slush, etc. can
make the brake linings slippery, resulting in
delayed braking effect.
If the vehicle is equipped with a trailer coupling
contact, clean the contact after driving in water or
mud.

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

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.

WHEELS AND TIRES
* Option/accessory.557
Checking tire pressure
Correct inflation pressure helps improve driving
stability, save fuel and increase the service life of
the tires.
Tire pressure decreases over time, which is nor-
mal. Tire pressure also varies depending on the
ambient temperature. Driving on under-inflated
tires could cause the vehicle to overheat and lead
to damage. Tire pressure affects traveling com-
fort, road noise and driving characteristics.
Check the pressure in the tires every month. Use
the recommended inflation pressure for cold tires
for optimal tire performance and wear. Under-
inflated or over-inflated tires could cause uneven
tread wear.
Use an air pressure gauge and check the infla-
tion pressure on all the tires, including the spare
tire 4
, at least once a month and before long trips.
Volvo strongly recommends buying a reliable air
pressure gauge, as the automatic gauges provi-
ded at service stations may be inaccurate.
WARNING •
Under-inflation is the most common
cause of tire failure and may result in
severe tire cracking, tread separation, or
"blow-out," with unexpected loss of vehi-
cle control and increased risk of injury.
• Under-inflated tires reduce the load car-
rying capacity of your vehicle.
Cold tiresInflation pressure should be checked when the
tires are cold.
The tires are considered to be cold when they
have the same temperature as the surrounding
(ambient) air.
This temperature is normally reached after the
vehicle has been parked for at least 3 hours.
After driving for approximately 1.6 km (1 mile),
the tires are considered to be warm. If you need
to drive longer than that to inflate the tires, check
and record the inflation pressure of the tires first
and inflate accordingly when you arrive at the
pump.
When the ambient temperature changes, so does
the inflation pressure. A 10-degree temperature
drop causes a corresponding drop in inflation
pressure of 1 psi (7 kPa). Check the inflation
pressure of the tires regularly and adjust to the correct pressure, which can be found on the vehi-
cle's tire information placard or certification label.
If you check inflation pressure when the tires are
warm, you should never release air. The tires
become warm after driving and it is normal for
warm tires to have an inflation pressure above
the recommended pressure for cold tires. A warm
tire with an inflation pressure equal to or under
the recommended pressure for cold tires could
be significantly under-inflated.Related information
