Condensation on the inside of the
windowsKeeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.Ice and snowAlways keep the air intake grille at the base of
the windshield free of snow.Cabin air filterReplace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
SensorsThe sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.Parking the vehicle in warm weatherIf your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof (option) for several minutes before
driving will help release the warm air from the
passenger compartment. When the engine is
running, close the windows and moonroof and
use the recirculation function for several
minutes to enable the air conditioning to cool
the compartment as quickly as possible.Windows and optional moonroofThe ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
AccelerationThe air conditioning is momentarily disen-
gaged during full-throttle acceleration.Climate control maintenanceSpecial tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.RefrigerantVolvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.4 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
8-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual1 A/C system: 2.3 lbs (1050 g)
The system also uses PAG oil.

Climate control system – general information
0391 Climate system blower
The climate system blower will be automati-
cally switched off when the engine is not run-
ning (even if the ignition key is in position I or
II) to avoid unnecessary battery drain. To acti-
vate the blower, turn the control to the desired
setting.
The climate system blower may start automat-
ically during a period of up to approximately
50 minutes after the ignition has been turned
off to remove condensation in the A/C evapo-
rator. It will run for 15 minutes and switch off
automatically.Passenger compartment blowerApproximately 50 minutes after the ignition is
turned off, the blower may come on automati-
cally, and run for seven minutes, to remove
condensation in the A/C evaporator.Blower function to reduce battery drainThe climate system's blower functions nor-
mally while the engine is running.
However, when the engine is switched off
(even if the ignition is switched to positions I or
II), the blower control will be automatically
switched off to avoid unnecessary battery
drain.The following points pertain if the ignition is on
but the engine in not running:
•
To restart the blower, turn the control knob
to the setting of your choice.
•
After approximately 2 minutes, the blower
speed will be reduced to avoid battery
drain.
You can reset the blower speed at any time.
Please be aware that the system has been
designed to reduce the blower's speed again
after 2 minutes, until the engine is started.
If the battery becomes drained:
•
LOW BATTERY, FAN IS REDUCED will
be displayed in the text window in the
instrument panel.
•
The yellow warning light in the instrument
panel (see page 54) will also light up.

Keys
G030177
Your vehicle is equipped with two coded
remote control transmitters with integrated
ignition key blades called Key Integrated
Remote (KIR).
To unlock/lock the vehicle using the key blade:•
Insert the key blade in the driver's door lock
and turn it once to unlock the driver's door
only.
•
Turn the key blade again (within 10 sec-
onds) to unlock all doors and the tailgate.
•
Turn the key blade once in the opposite
direction to lock all doors and the tailgate.Use the switch on the driver's door armrest to
lock/unlock the vehicle from the inside.
WARNING
If the doors are locked while driving, this
may hinder rapid access to the occupants
of the vehicle in the event of an accident.
(Also see information on "Child safety locks"
NOTE
To help prevent accidentally locking the
keys in the vehicle, the central locking sys-
tem is designed to unlock the doors imme-
diately if the key is left in the ignition switch,
the vehicle is locked using the lock button
on the door and the door is then closed. A
sound from the lock will be audible at this
time.
Please note that this function will not unlock
the doors if the engine is running.Immobilizer (start inhibitor)Each of the keys supplied with your vehicle
contains a coded transmitter. The code in the
key is transmitted to an antenna in the ignition
switch where it is compared to the code stored
in the start inhibitor module. The vehicle will
start only with a properly coded key.
Each key has a unique code, which your Volvo
retailer uses if new keys are required. A maxi-mum of six remote controls/keys can be pro-
grammed and used for one vehicle.
If you misplace a key, take the other keys to an
authorized Volvo retailer for reprogramming as
an antitheft measure.
If 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 inter-
ference 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.
NOTE
This device complies with part 15 of the
FCC rules. Operation is subject to the fol-
lowing condition: (1) This device may not
cause harmful interference, and (2) this
device must accept any interference
received, including interference that may
cause undesired operation.

NOTE
•
If an airbag deploys, your vehicle's SRS
control module will attempt to automat-
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 control.
•
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.

would hinder rapid access to the occu-
pants in an accident or emergency.

06 Starting and drivingGeneral information
06128
Engine oilAlthough 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 requirementsDeposit 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
external 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 effec-
tiveness of the emission control system and
could result in loss of emission warranty cov-
erage. State and local vehicle inspection pro-
grams will make detection of misfueling easier,
possibly resulting in emission test failure for
misfueled 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 129 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.

06 Starting and driving
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.

06 Starting and drivingFuel requirements

WARNING
Driving with the tailgate open: Driving with
the tailgate open could lead to poisonous
exhaust gases entering the passenger com-
partment.•
If the tailgate must be kept open for any
reason, proceed as follows:
•
Close the windows
•
Set the ventilation system control to air
flow to floor, windshield and side win-
dows and blower control to its highest
setting.
Weight distribution affects handlingAt the specified curb weight your vehicle has a
tendency to understeer, which means that the
steering wheel has to be turned more than
might seem appropriate for the curvature of a
bend.
This ensures good stability and reduces the
risk of rear wheel skid. Remember that these
properties can alter with the vehicle load.
The heavier the load in the cargo area, the less
the tendency to understeer.Handling, roadholdingVehicle load, tire design and inflation pressure
all affect vehicle handling. Therefore, check
that the tires are inflated to the recommendedpressure according to the vehicle load. See
"Tire pressure" section.
Loads should be distributed so that capacity
weight or maximum permissible axle loads are
not exceeded.
Conserving electrical currentKeep the following in mind to help minimize
battery drain:•
When the engine is not running, avoid turn-
ing the ignition key to position II (see
page 135). Many electrical systems (the
audio system, the optional infotainment/
navigation systems, power windows, etc)
will function with the ignition key in position
I. This position reduces drain on the bat-
tery.
•
Please keep in mind that using systems,
accessories, etc that consume a great deal
of current when the engine is not running
could result in the battery being completely
drained.NOTE
A warning message will be displayed in the
text window in the instrument panel when
the battery charge is low.
