ically unlock all doors.
•The key blade may also be used to lock
and unlock the doors, and to activate
and deactivate the alarm system.
•To avoid leaving your keys in the vehi-
cle, make a habit of always locking the
vehicle with the remote key.
•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.
•The vehicle can be locked even if a door
is open. When the door(s) are closed,
they will be locked. Please be aware
that the keys could be locked in the car
when this is done.
Automatic re-lockingIf the doors are unlocked, the locks will auto-
matically reengage (re-lock) and the alarm will
rearm after 2 minutes unless a door or the tail-
gate has been opened. This helps prevent the
car from inadvertently being left unlocked.

Engine oil
Although some oil consumption occurs during
normal engine operation, more oil is consumed
when the engine is new as the internal parts
generate higher friction while wearing-in to
each other. From the time the engine is new
until the first maintenance is performed, the oil
consumption could be higher than normal. For
this reason, it is especially important to check
the oil every time you refuel your vehicle during
this period, see page 209.
Fuel requirements
Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gas-
oline to control engine deposits. Detergent
gasoline is effective in keeping injectors and
intake valves clean. Consistent use of deposit
control gasolines will help ensure good driva-
bility and fuel economy. If you are not sure
whether the gasoline contains deposit control
additives, check with the service station oper-
ator.
NOTE
Volvo does not recommend the use of exter-
nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps deliv-
ering unleaded gasoline be labelled "UNLEA-
DED". Only these pumps have nozzles which
fit your vehicle's filler inlet. It is unlawful to dis-
pense leaded fuel into a vehicle labelled
"unleaded gasoline only". Leaded gasoline
damages the three-way catalytic converter and
the heated oxygen sensor system. Repeated
use of leaded gasoline will lessen the effective-
ness 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, pos-
sibly resulting in emission test failure for mis-
fueled 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 affec-
ted, and the Check Engine Light (malfunc-
tion indicator lamp) located on your instru-
ment panel may light. If this occurs, please
return your vehicle to a trained and qualified
Volvo service technician for maintenance.
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 indi-
cating 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 sea-
sonal air quality standards, some areas require
the use of "oxygenated" fuel.
Volvo allows the use of the following "oxygen-
ated" fuels; however, the octane ratings listed
on page 131 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 "Gaso-
hol".
Ethers – MTBE: Fuels containing up to 15%
MTBE may be used.

133 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 63) 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 270 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.

135 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 100.
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.
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.
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
An extra mat on the driver's floor can cause
the accelerator pedal to catch. Check that
the movement of the accelerator pedal is
not impeded. No more than one protective
floor covering may be used at one time.
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 137.

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

138
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).

06 Starting and driving
Difficult driving conditions

139 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.
