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.

139 Starting the engine
WARNING
Before starting, check that the seat, steering
wheel and mirrors are adjusted properly.
Make sure the brake pedal can be
depressed completely. Adjust the seat if
necessary, see page 104.
1. Fasten the seat belt.
2. Apply the parking brake (hand brake) if not
already set. The gear selector is locked in
the P position (SHIFTLOCK).
3. Without touching the accelerator pedal,
turn the ignition key
1 to the starting posi-
tion. Allow the starter to operate for up to
10 seconds. Release the key as soon as
the engine starts
2. If the engine fails to
start, repeat this step.
WARNING
•Never use more the one floor mat at one
time on the driver's floor. An extra mat
on the driver's floor can cause the
accelerator and/or brake pedal to
catch. Check that the movement of
these pedals is not impeded.
•Volvo's floor mats are specially manu-
factured for your car. They must be
firmly secured in the clips on the floor so
that they cannot slide and become trap-
ped under the pedals on the driver's
side.
NOTE
•If the key blade section of the remote is
not fully folded out when starting the
vehicle, the immobilizer function may
make it impossible to start the engine.
•After a cold start, idle speed may be
noticeably higher than normal for a
short period. This is done to help bring
components in the emission control
system to their normal operating tem-
perature as quickly as possible, which
enables them to control emissions and
help reduce the vehicle's impact on the
environment.
•To release the gear selector from the P
(Park) position, the engine must be run-
ning (or the ignition key must be in posi-
tion II) and the brake pedal must be
depressed.
•Select the desired gear. The gear
engages after a very slight delay which
is especially noticeable when selecting
R.
1If two of the keys to your vehicle are close together, e.g. on the same key ring when you try to start the vehicle, this could cause interference in the immobilizer system and result in the vehicle not
starting. If this should occur, remove one of the keys from the key ring before trying to start the vehicle again.
2On vehicles equipped with the autostart feature, release the key immediately. See also page 141.

NOTE
Your vehicle is equipped with a KEYLOCK
system. When the engine is switched off,
the gear selector must be in the P position
before the key can be removed from the
ignition switch.
When starting in cold weather, the trans-
mission may shift up at slightly higher
engine speeds than normal until the auto-
matic transmission fluid reaches normal
operating temperature.
NOTE
Do not race a cold engine immediately after
starting. Oil flow may not reach some lubri-
cation points fast enough to prevent engine
damage.
WARNING
Always place the gear selector in Park and
apply the parking brake before leaving the
vehicle. Never leave the vehicle unattended
with the engine running.
•Always open garage doors fully before
starting the engine inside a garage to
ensure adequate ventilation. The
exhaust gases contain carbon monox-
ide, which is invisible and odorless but
very poisonous.
CAUTION
Automatic transmission
•The engine should be idling when you
move the gear selector. Never acceler-
ate until after you feel the transmission
engage! Accelerating immediately after
selecting a gear will cause harsh
engagement and premature transmis-
sion wear.
•Selecting P or N when idling at a stand-
still for prolonged periods of time will
help prevent overheating of the auto-
matic transmission fluid.

starter motor will then operate automatically
(for up to ten seconds) until the engine starts.
Steering wheel lockThe steering wheel lock might be under tension
when the vehicle is parked.
Turn the steering wheel slightly to free the igni-
tion key.
In order to help reduce vehicle theft, make sure
the steering wheel lock is engaged before leav-
ing the vehicle.
WARNING
Never switch off the ignition (turn the ignition
key to position 0) or remove the key from the
ignition switch while the vehicle is in motion.
This could cause the steering wheel to lock,
which would make the vehicle impossible to
steer.

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.
