Drive economically and environmentally con-
scious by thinking ahead, avoiding rapid starts
and stops and adapting driving style and speed
to the current traffic conditions.
Planning for electric drivingIt is important to plan electric motor use carefully
to achieve the best possible mileage:
Charge
• Charge the vehicle regularly by plugging it
into an electrical outlet. Make it a habit to
always begin trips with the hybrid battery fully
charged.
• Locate charging stations along your route.
• If possible, choose parking spots with charg-
ing stations.
NOTE Charge the vehicle from the electricity grid as
often as possible!
Preconditioning
•
Whenever possible, precondition the vehicle
before driving by connecting the charging
cable to an electrical outlet.
• Avoid parking the vehicle somewhere where
the interior will become too hot or too cold
while the vehicle is parked. If possible, park
the vehicle in a climate-controlled garage. •
During a short drive after passenger com-
partment preconditioning, turn off the pas-
senger compartment fan or the air condition-
ing in a hot climate.
• If preconditioning is not possible when it is
cold outside, use seat and steering wheel
heating first. Avoid heating the entire pas-
senger compartment to reduce the amount
of current being taken from the hybrid bat-
tery.

• "Hold" and "Charge" functions (p. 459) Factors affecting electric motor
range
A number of factors affect the electric motor's
driving range. The ability to achieve a long driv-
ing range varies according to the outside condi-
tions and to how the vehicle is driven. The certified value for the distance that can be
driven using the electric motor should not be
considered an expected driving range. The actual
range is dependent on a number of factors.
Factors affecting driving rangeThe driver can influence some factors affecting
driving range, but not all.
The longest range is achieved under very favora-
ble conditions when all factors positively influ-
ence range.
Factors the driver cannot control
There are several outside conditions that affect
range to varying degrees:
• the current traffic situation
• driving short distances
• topography
• ambient temperature and headwinds
• road conditions and road surface.
The following table shows the approximate rela-
tionship between ambient temperature and driv-
ing range with normal climate settings and with
climate settings turned off. Up to a certain limit, warmer ambient tempera-
tures increase the electric motor's driving range. Ambient tem-

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

Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: • blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

Driving with a trailer (p. 472)
• Towing capacity and tongue weight (p. 660) Driving with a trailer
There are a number of things to consider when
towing a trailer, such as the towbar, the trailer
and how the load is distributed in the trailer.
Load-carrying capacity is determined by the vehi-
cle's curb weight. The total weight of all passen-
gers and any installed accessories, e.g. towbar,
reduces the vehicle's load-carrying capacity by
the corresponding amount.
• Towbars used on the vehicle must be
approved for the applicable use.
• Distribute the load on the trailer so that the
weight on the towbar complies with the
specified maximum towball weight. The
tongue weight is calculated as part of the
vehicle's payload.
• Increase the tire pressure to the recom-
mended pressure for a full load.
• The engine is subjected to more load than
usual when towing a trailer.
• Towing a trailer affects the vehicle's han-
dling, durability and driving economy.
• Do not drive with a heavy trailer when the
vehicle is very new. Wait until the mileage
has reached at least 1000 km (620 miles).
• On long and steep downgrades, the vehicle's
brakes are subjected to much more load
than usual. When manually shifting, down-
shift and adapt speed accordingly. •
Follow applicable regulations regarding per-
mitted speed and weight.
• Drive slowly when towing a trailer up a long
and steep incline.
• The maximum trailer weights given only apply
to altitudes up to 1000 meters (3280 feet)
above sea level. At higher altitudes, engine
power (and thus the vehicle's climbing ability)
is decreased due to the reduced air density,
and the maximum trailer weight must there-
fore be reduced. The weight of the vehicle
and trailer must be decreased by 10% for
each additional 1000 m (3280 feet) or part
thereof.
• Avoid driving with a trailer on inclines of more
than 12%.
• Avoid overloading and other incorrect use.
• The trailer's brakes must be balanced with
the vehicle's brakes to help ensure safe
stops (follow applicable local regulations).

474 Trailer Stability Assist*
Trailer Stability Assist (TSA 8
) is a function
designed to help stabilize a vehicle that is tow-
ing a trailer when the vehicle and trailer have
begun to sway. The function is part of the Elec-
tronic Stability Control system ESC 9
.
Reasons for swayingA vehicle towing a trailer may begin to sway for
various reasons. Normally this only occurs at high
speeds. However, if the trailer is overloaded or
unevenly distributed, e.g. too far back, there is a
risk of swaying even at low speeds.
Swaying may be caused by factors such as:
• The vehicle and trailer are hit by a sudden,
strong crosswind.
• The vehicle and trailer are traveling on an
uneven road or over a bump.
• Sudden movements of the steering wheel.
Once swaying has begun, it can be difficult or
impossible to stop it. This makes the vehicle and
trailer difficult to control and there is a risk of
swerving into oncoming traffic or driving off the
road.
Trailer Stability Assist functionTrailer Stability Assist continuously monitors the
vehicle's movements, particularly lateral move- ments. If swaying is detected, the brakes are
applied individually on the front wheels, which has
a stabilizing effect on the vehicle and trailer. This
is often enough to enable the driver to regain
control of the vehicle.
If the Trailer Stability Assist function's first
attempt is not adequate to stop the swaying
motion, the brakes are applied on all wheels and
engine power is temporarily reduced. As the
swaying motion begins to decrease and the vehi-
cle and trailer have once again become stable,
TSA stops regulating the brakes/engine power
and the driver regains control of the vehicle.
NOTE
Trailer Stability Assist is deactivated if the
driver selects the sport mode by deactivating
ESC in the center display's menu system. Trailer Stability Assist may not intervene if the
driver tries to compensate for the swaying motion
by moving the steering wheel rapidly, because
the system will then not be able to determine if it
is the trailer or the driver causing the swaying. When Trailer Stability Assist is
activated, the ESC symbol is
displayed in the instrument
panel.

3. Select Disable Leveling Control.
The vehicle's location and ground clearance
determine if it can be lifted onto a tow truck. If
the incline of the tow truck is too steep or if the
ground clearance under the vehicle is insufficient,
attempting to pull it up may result in damage. In
this case, the vehicle should only be lifted with
the tow truck's lifting equipment.
