Reverse position.Rearview mirror with compass (option)
G026965
The upper left-hand corner of the rearview mir-
ror has an integrated display that shows the
compass direction toward which the car is
pointing. Eight different directions can be dis-
played:
N, NE, E, SE, S, SW, W
and
NW
. The
display shows your car's orientation with
respect to true north.
If the compass is activated, it will be displayed
automatically when the ignition is in postilion IIor when the engine is running. The compass
can be switched off or on by pressing the inset
button on the rear side of the mirror (see the
inset illustration). This can be done with
straightened paperclip or similar object. The
button is recessed approximately 1 in. (2.5 cm)
in the mirror.

Magnetic zonesThe earth is divided into 15 magnetic zones.
The compass is initially set for the zone to
which the car was delivered, and should
always be adjusted if the car is driven to a new
magnetic zone. To do so:

Fuel requirements
06``129 Octane rating
Minimum octane
G028920
Typical pump octane labelVolvo recommends premium for best perform-
ance, but using 87 octane or above will not
affect engine reliability.
Volvo engines are designed to achieve rated
horsepower, torque, and fuel economy per-
formance using premium 91 octane fuel.Demanding drivingIn demanding driving conditions, such as oper-
ating the vehicle in hot weather, towing a trailer,
or driving for extended periods at higher alti-
tudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or to
change gasoline brands to fully utilize yourengine's capacity, and for the smoothest pos-
sible operation.
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 as a
knock inhibitor, and do not use lead additives.
Besides damaging the exhaust emission con-
trol 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
precautions. 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, thicken-
ers, 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
Carbon monoxide is a poisonous, colorless,
and odorless gas. It is present in all exhaust
gases. If you ever smell exhaust fumes
inside the vehicle, make sure the passenger
compartment is ventilated, and immediately
return the vehicle to a trained and qualified
Volvo service technician for correction.

137 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 waterThe 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.

06 Starting and driving
Automatic transmission
06``139
NOTE
The gear selector must be in the D (Drive)
position for kickdown to function.Manual shifting – GeartronicYou can move the gear selector freely between
theMAN (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" feature
1 reduces engine speed
and help saves fuel.
The currently selected gear will be displayed in
the instrument panel (see page 54).
•
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 drivingIf 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 54) 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.

06 Starting and driving
Brake system
06``143 BRAKE Brake circuit malfunction
The brake system is a hydraulic system con-
sisting of two master cylinders and two sepa-
rate brake circuits. If a problem should occur in
one of these circuits, it is still possible to stop
the vehicle with the other brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in the reservoir.
NOTE
Press the brake pedal hard and maintain
pressure on the pedal – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a
Brake failure – Service
urgent
message is displayed in the text
window:DO NOT DRIVE
. Have the vehicle
towed to a trained and qualified Volvo serv-
ice technician and have the brake system
inspected.
NOTE
When the vehicle is at a standstill and the
engine is idling, e.g. at a traffic light and the
brake pedal is depressed, the pedal may go
down slightly. This is a normal function of
the power-assisted brake system.Power brakes function only when the
engine is runningThe power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, the brake
pedal must be pressed approximately four
times harder than usual to make up for the lack
of power assistance. This can happen for
example when towing your vehicle or if the
engine is switched off when the vehicle is roll-
ing. The brake pedal feels harder than usual.Water on brake discs and brake pads
affects brakingDriving in rain and slush or passing through an
automatic car wash can cause water to collect
on the brake discs and pads. This will cause a
delay in braking effect when the pedal is
depressed. To avoid such a delay when the
brakes are needed, depress the pedal occa-
sionally when driving through rain, slush etc.
This will remove the water from the brakes.Check that brake application feels normal. This
should also be done after washing or starting
in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less efficient than when driving on
level roads. To reduce the strain on the brakes,
shift into a lower gear and let the engine help
with the braking. Do not forget that, if you are
towing a trailer, the brakes will be subjected to
a greater than normal load.Anti-lock brakes (ABS)
If the warning lamp lights up there
is a malfunction of the ABS system
(the standard braking system will
however function) and the vehicle
should be driven cautiously to a
trained and qualified Volvo service technician
for inspection. The Anti-lock Braking System
(ABS) helps to improve vehicle control (stop-
ping and steering) during severe braking con-
ditions by limiting brake lockup. When the
system "senses" impending lockup, braking
pressure is automatically modulated in order to
help prevent lockup, which could lead to a skid.
The system performs a self-diagnostic test
when the engine is started and when the
