137 Fuel filler door
G027073
The fuel filler cap can be placed on the hook on
the fuel filler door while refueling
Press the button on the light switch panel (see
the illustration on page 67) when the vehicle is
at a standstill to unlock the fuel filler door.
Please note that the fuel filler door will remain
unlocked until the vehicle begins to move for-
ward. An audible click will be heard when the
fuel filler door relocks.
If you intend to leave your vehicle while it is
being refueled, this feature enables you to lock
the doors/tailgate while leaving the fuel filler
door unlocked.You can also keep the vehicle locked if you
remain inside it during refueling. The central
locking button does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and
is completely closed after refueling.
Open the fuel filler cap slowly during hot
weather.
NOTE
During a transitional period, a small number
of service stations may still have fuel noz-
zles that are not compatible with the fuel
filler neck on vehicles equipped with the
evaporative control system.
RefuelingThe fuel tank is designed to accommodate
possible expansion of the fuel in hot weather.
See page 284 for fuel tank volume. Be aware
that the "usable" tank capacity will be some-
what less than the specified maximum. When
the fuel level is low, such factors as ambient
temperature, the fuel's "Reid vapor pressure"
characteristics, and terrain can affect the fuel
pump's ability to supply the engine with an
adequate supply of fuel. Therefore, it is advis-
able to refuel as soon as possible when theneedle nears the red zone, or when the fuel
warning light comes on.
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 gasoline fumes, resulting in fire and
injury.

CAUTION
•Do not refuel with the engine running1.
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
1.
•Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much fuel
in the tank in hot weather conditions can
cause the fuel to overflow. Overfilling
could also cause damage to the emis-
sion control systems.
•Avoid spilling gasoline during refueling.
In addition to causing damage to the
environment, gasolines containing
alcohol can cause damage to painted
surfaces, which may not be covered
under the New Vehicle Limited War-
ranty.
•Do not use gasolines containing meth-
anol (methyl alcohol, wood alcohol).
This practice can result in vehicle per-
formance deterioration and can dam-
age critical parts in the fuel system.
Such damage may not be covered
under the New Vehicle Limited War-
ranty.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.

06 Starting and driving
Economical driving

142
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 fol-
lowing rules:
•Bring the engine to normal operating tem-
perature 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 vehicle
for driving short distances. This does not
allow the engine to reach normal operating
temperature.
•Drive carefully and avoid rapid acceleration
and hard braking.
•Use the transmission's D (Drive) position
as often as possible and avoid using "kick-
down" to help improve fuel economy.
•Do not exceed posted speed limits.
•Avoid carrying unnecessary items (extra
load) in the vehicle.
•Maintain correct tire pressure. Check tire
pressure regularly (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 also fuel con-
sumption.
•At highway driving speeds, fuel consump-
tion 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 that decrease gas mileage
are:
•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.
CAUTION
Drive slowly and carefully if going through
standing water (i.e. flooded roadways, etc.).
Damage to the engine could result if excess
water is drawn in through the air intake sys-
tem. Never drive the vehicle in water deeper
than 18 inches (48 cm).

143 Driving on rough/unpaved surfaces
The Volvo XC90 is designed primarily for on-
road driving, and it has excellent handling cha-
racteristics on very rough or unpaved roads.
When driving on poorly maintained or unpaved
roads, please keep the following in mind:
•Reduce speed on rough surfaces to mini-
mize possible damage to the vehicle's
underbody.
•When driving on soft surfaces such as dry
sand or snow, try to avoid stopping if at all
possible.
WARNING
•Avoid driving diagonally across steep
inclines as this could increase the risk of
a roll-over. Try to drive straight up or
down the slope.
•If the road is very steep, avoid turning
the vehicle around to help avoid the risk
of rolling over. Back the vehicle up or
down the incline instead.
NOTE
Avoid driving on steep inclines if the fuel
tank is nearly empty. If the flow of fuel to the
engine is interrupted due to the vehicle's
angle of inclination, this could result in dam-
age to the three-way catalytic converter. We
recommend keeping the fuel tank at least
half full when driving on steep inclines.
Driving through water
The vehicle can be driven through water up to
a depth of approximately 16 inches (40 cm), at
a maximum speed of 6 mph (10 km/h).
Take particular care when driving through flow-
ing water.
Clean the electrical connections for trailer wir-
ing after driving in mud or water.
When driving through water, maintain low
speed and do not stop in the water.
WARNING
After driving through water, press lightly on
the brake pedal to ensure that the brakes
are functioning normally. Water or mud can
make the brake linings slippery, resulting in
delayed braking effect.
CAUTION
•Engine damage will occur if water is
drawn into the air cleaner.
•If the vehicle is driven through water
deeper than 18 in (48 cm), water may
enter the differential and the transmis-
sion. This reduces the oil's lubricating
capacity and may shorten the service
life of these components.
•Do not allow the vehicle to stand in
water up to the door sills longer than
absolutely necessary. This could result
in electrical malfunctions.
•If the engine has been stopped while the
car is in water, do not attempt to restart
the engine. Have the car towed out of
the water.

P (Park)Use this position when starting the engine or
parking the vehicle.
Never use P while the vehicle is in motion.
The parking brake should also be set whenever
the vehicle is parked.
The gear selector is mechanically locked in
the P position (SHIFTLOCK). To release the
gear selector from this position, the engine
must be running (or the ignition key must be in
position II) and the brake pedal must be
depressed.
N (Neutral)Neutral – no gear engaged. Use the parking
brake.
WARNING
Never leave the vehicle unattended when
the engine is running. If, by mistake, the gear
selector is moved from P, the vehicle may
start moving.
R (Reverse)Never engage R while the vehicle is moving.
D (Drive)D is the normal driving position and should be
used as often as possible to help improve fuel
economy. The vehicle should not be moving
when shifting from R to the D position.
NOTE
The transmission has 6 forward speeds.

Shift gate positions
Depress the button on the front of the gear
selector knob to move between the R, N, D,
and P positions.
KickdownAutomatic 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 acceler-
ation or when passing at highway speeds.

NOTE
The gear selector must be in the D (Drive)
position for kickdown to function.
Manual shifting – Geartronic
You can move the gear selector freely between
the MAN (Manual) and D (Drive) positions to
select forward gears while driving. Gears 3, 4,
5, and 6 have a "lock-up" function which
reduces engine speed and helps save fuel.
NOTE
Reverse, Neutral, and Park cannot be
selected in Geartronic mode.
•A "lock-up" feature1 reduces engine speed
and help saves fuel.
The currently selected gear will be displayed in
the instrument panel (see page 58).
•To access the MAN shifting position from
D, move the gear selector to the left to
MAN.
•To return to the D positions from MAN,
move the gear selector to the right.
While driving
If you select the MAN position while driving, the
gear that was being used in the D position will
also initially be selected in MAN 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 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 position, 3rd
gear is the highest gear that may be
selected.
W – Winter/Wet driving mode –
enhanced vehicle traction
G030859
Press the W button at the base of the gear
selector to engage/disengage this driving
mode (see illustration). The
W symbol will
appear in the display (see page 58) when the
function is activated.
This mode may be selected for starting/moving
off on slippery roads. The vehicle starts off in
3rd gear to help maintain traction. First and
second gears will only be used during kick-
down.
1Six-speed transmission: gears 2, 3, 4, 5, and 6.

G030860
Follow these instructions to jump start your
vehicle's dead battery or to jump start another
vehicle's dead battery using your vehicle.
Although your vehicle's battery is located
under the floor of the cargo area, jumper cables
should be connected in the engine compart-
ment, to the points shown in the illustrations.
If the 12-volt auxiliary battery to be used is in
another vehicle, check that the vehicles are not
touching to prevent premature completion of a
circuit. Be sure to follow jump starting instruc-
tions provided for the other vehicle.
To jump start your vehicle:1. Switch off the ignition.2. First connect the auxiliary battery positive
(+) terminal (1) to the positive (+) terminal in
your vehicle's engine compartment (2),
located under a small black plastic cover
attached to the fuse box cover, marked
with a "+" sign. Remove the cover on the
main fuse box if necessary to access this
terminal. Then connect the auxiliary bat-
tery's negative (–) terminal (3) to the ground
point in your vehicle's engine compartment
(4).
3. Start the engine in the assisting vehicle,
then start the engine in the vehicle with
dead battery.
4. After the engine has started, first remove
the negative (–) terminal jumper cable.
Then remove the positive (+) terminal
jumper cable.

jump starting can lead to personal
injury.

06 Starting and driving
All Wheel Drive*
06
148* Option/accessory, for more information, see Introduction.
All Wheel Drive (AWD) – general
information
Your Volvo can be equipped with an electron-
ically controlled All Wheel Drive system*, which
means that power is distributed automatically
between the front and rear wheels. Under nor-
mal driving conditions, most of the engine's
power is directed to the front wheels. However,
if there is any tendency for the front wheels to
spin, an electronically controlled coupling dis-
tributes power to the wheels that have the best
traction.
Tire dimensionsVolvo recommends that you always drive on
tires of the same brand, size, construction
(radial), tread pattern, load-, speed-, traction-,
temperature-, and treadwear rating. Never
drive on mixed tires, except for brief periods
when the temporary spare tire is in use.
Always use properly inflated tires of correct
dimensions. Tire size and inflation pressures
are shown on the tire inflation pressure plac-
ards, located on the driver's side B-pillar (the
structural member at the side of the vehicle, at
the rear of the driver's door opening), or on the
inside of the fuel filler door on Canadian mod-
els.
Temporary SpareThe temporary spare tire is for temporary, low-
speed, short-distance use only. Replace it with
a full-sized tire as soon as possible. Do not
drive on the temporary spare at speeds above
50 m.p.h. (80 km/h).
NOTE
Never install snow chains on a temporary
spare.
