131 Octane rating
Minimum octane
G028920
Typical pump octane label
Volvo 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.

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.

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 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 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 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

145 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 running
The 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, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-
ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving 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 sys-
tem "senses" impending lockup, braking pres-
sure 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

06 Starting and driving
Brake system
06
146
vehicle first reaches a speed of approxi-
mately 12 mph (20 km/h). The brake pedal will
pulsate several times and a sound may be
audible from the ABS control module. This is
normal.
To obtain optimal effect from the ABS system,
constant pressure should be kept on the brake
pedal. Do not pump the brake pedal.
The switching of the ABS modulator will be
audible and the brake pedal will pulsate during
braking. Please be aware that ABS does not
increase the absolute braking potential of the
vehicle. While control will be enhanced, ABS
will not shorten stopping distances on slippery
surfaces.
ABS with EBD (Electronic Brake Force
Distribution)
EBD is an integrated part of the ABS system.
EBD regulates the hydraulic pressure to the
rear brakes to help provide optimal braking
capacity. The brake pedal will pulsate during
braking, which is normal.
If the BRAKE and ABS warning lights come on
at the same time, this could indicate a fault in
the brake system.
1. Stop the vehicle in a suitable place and
switch off the engine.
2. Restart the engine.
•If both warning lights go off, no further
action is required.
•If both lights are still on after the engine has
been restarted, switch off the engine again
and check the brake fluid level (see
page 212 for the location of the brake fluid
reservoir).
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.
•If the brake fluid level is above the MIN
mark, drive carefully to a trained and quali-
fied Volvo service technician and have the
brake system inspected.
Emergency Brake Assistance (EBA)The EBA function is designed to provide full
brake effect immediately in the event of sud-
den, hard braking. The system is activated by
the speed with which you depress the brake
pedal.
NOTE
•When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

* Option/accessory, for more information, see Introduction.149
Front/rear park assist
The park assist system is designed to assist
you when driving into parking spaces, garages,
etc. It utilizes four ultrasound sensors located
in one or both bumpers to measure the dis-
tance to a vehicle, object, or a person who may
be close to the front or rear of your vehicle.
Park assist is available in two versions:
•Rear bumper only
•Front and rear bumpers
WARNING
Park Assist is an information system, NOT a
safety system. This system is designed to
be a supplementary aid when parking the
vehicle. It is not, however, intended to
replace the driver's attention and judge-
ment.
Function
The system is activated automatically when the
vehicle is started. The indicator light in the but-
ton in the center console illuminates.
•The front park assist system is active from
the time the engine is started until the vehi-
cle exceeds a speed of approximately
10 mph (15 km/h). It is also active when the
vehicle is backing up.
•Rear park assist is active when the engine
is running and reverse gear has been
selected.
Rear park assistThe distance monitored behind the vehicle is
approximately 5 ft (1.5 m). The signal comes
from the rear speakers.
The system must be deactivated when towing
a trailer, carrying bicycles in a rear-mounted
carrier, etc, which could trigger the rear park
assist system's sensors.
NOTE
Rear park assist is deactivated automati-
cally when towing a trailer if Volvo genuine
trailer wiring is used.
Front park assistThe distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
•It may not be possible to combine auxiliary
headlights and front park assist since
these lights could trigger the system's sen-
sors.
Activating/deactivating park assist
The system is activated automatically when the
vehicle is started.
•Press the Park assist button on the center
console (see page 60) to temporarily deac-
tivate the system(s). The indicator light in
the button will go out when the system has
been deactivated.
•Park assist will be automatically reactiva-
ted the next time the engine is started, or if
the button is pressed (the indicator light in
the button will illuminate).
