145 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
store-bought fuel injector cleaning addi-
tives.
Unleaded fuel
Each 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
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 theuse of the following "oxygenated" fuels; how-
ever, the octane ratings listed on this page
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.
MethanolDo not use gasolines containing methanol
(methyl alcohol, wood alcohol). This practice
can result in vehicle performance deterioration
and can damage critical parts in the fuel sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.
Fuel filler door
Press the button on the light switch panel (see
the illustration on page 66) with the ignition
switched off 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/trunk while leaving the fuel filler door
unlocked.

06 Starting and driving
Rear park assist*
06

* Option/accessory, for more information, see Introduction.171 Introduction
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 the rear bumper to measure the distance to
a vehicle, object or a person who may be close
to the rear of your vehicle.
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. Park
assist monitors the area behind the vehicle
when the engine is running and reverse gear
has been selected.
The 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.
Activating/deactivating park assist
G021267
Park Assist button (right button in the illustration)
The system is activated automatically when the
vehicle is started.

Press the Park assist button on the center
console to temporarily deactivate the sys-
tem. The indicator light in the button will go
out when the system has been deacti-
vated.

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).

Audible signals from the park assist
system
The Park Assist system uses an intermittent
tone that pulses faster as you come close to an
object, and becomes constant when you are
within approximately 1 ft (30 cm) of an object
behind the vehicle. If the volume of another
source from the audio system is high, this will
be automatically lowered.
Faults in the system
If the information symbol illumi-
nates and PARK ASSIST
SERVICE REQUIRED is shown
on the information display, this
indicates that the system is not
functioning properly and has been disengaged.
Consult a Volvo retailer or authorized Volvo
service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.
Cleaning the sensors
Park assist sensors
The sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and a suitable car washing deter-
gent.
Ice and snow covering the sensors may cause
incorrect warning signals.
NOTE
If the sensors are obstructed by e.g., dirt,
snow, or ice, this could result in false warn-
ing signals from the park assist system.

07 Wheels and tires
Tire Sealing System*
07
196* Option/accessory, for more information, see Introduction.
NOTE
The air pressure gauge will temporarily
show an increase in pressure to approxi-
mately 88 psi (6 bar) while the sealing com-
pound is being pumped into the tire. The
pressure should return to a normal level
after approximately 30 seconds.
11. Within seven minutes, inflate the tire to
between 22—44 psi (1.8—3.0 bar). Switch
off the compressor briefly to get a clear
reading from the pressure gauge. The
compressor should not be used for more
than 10 minutes at a time to avoid over-
heating.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If the pressure remains below 22 psi
(1.8 bar) after approximately seven minutes,
turn off the compressor. In this case, the
hole is too large to be sealed and the vehicle
should not be driven.
12. Switch off the compressor and disconnect
the electrical wire from the 12-volt socket.
13. Unscrew the hose from the tire’s inflation
valve and reinstall the valve cap.
14. Immediately drive the vehicle for approxi-
mately 2 miles (3 km) at a maximum speed
of 50 mph (80 km/h) to distribute the seal-
ing compound in the tire.
CAUTION
If your vehicle is equipped with the Tire
Pressure Monitoring System (TPMS), the
use of the sealing compound may lead to
incorrect tire pressure readings or in rare
cases, damage to the tire pressure sensor.
Use the tire sealing system to check and
adjust the damaged tire's inflation pressure.
NOTE
•Safely stow the tire sealing system in a
convenient place as it will soon be used
again to check the tire’s inflation pres-
sure.
•The empty bottle of sealing compound
cannot be removed from the bottle
holder. Consult a trained and qualified
Volvo service technician to have the
bottle removed and properly disposed
of.
WARNING
If heavy vibrations, unsteady steering
behavior, or noises should occur while driv-
ing, reduce speed and park the vehicle in a
safe place. Recheck the tire for bumps,
cracks, or other visible damage, and
recheck its inflation pressure. If the pressure
is below 19 psi (1.3 bar), do not continue
driving. Have the vehicle towed to a trained
and qualified Volvo service technician.
Stage 2: Checking inflation pressure1. Connect the tire sealing system as descri-
bed in stage 1.
2. Refer to the inflation pressure tables for the
correct inflation pressure. If the tire needs
to be inflated, start the tire sealing system’s
compressor. If necessary, release air from
the tire by turning the air release knob
counterclockwise.
CAUTION
The compressor should not be used for
more than 10 minutes at a time to avoid
overheating.
WARNING
If you interrupt your trip for more than 1
hour, check the inflation pressure in the
damaged tire again before continuing.

07 Wheels and tires
Tire Pressure Monitoring System (TPMS)
07
200
Introduction
The tire pressure monitoring system1 uses sen-
sors mounted in the tire valves to check infla-
tion pressure levels. When the vehicle is mov-
ing at a speed of approximately 20 mph
(30 km/h) or faster, these sensors transmit
inflation pressure data to a receiver located in
the vehicle.
NOTE
USA – FCC ID: KR5S122780002
This device complies with part 15 of the
FCC rules. Operation is subject to the fol-
lowing conditions: (1) This device may not
cause harmful interference, and (2) this
device must accept any interference
received, including interference that may
cause undesired operation.
When low inflation pressure is detected, TPMS
will light up the tire pressure warning light
(also referred to as a telltale) in the instrument
panel and will display one of the following mes-
sages in the text window:
LOW TIRE PRESS.
CHECK TIRES or VERY LOW TIRE
PRESSURE.
NOTE
If a fault occurs in TPMS, the tire pressure
warning light will flash for approximately
1 minute and
TIRE PRESS SYST
SERVICE REQUIRED will be displayed.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your
vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation
pressure label, you should determine the
proper tire inflation pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pres-
sure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when
the low tire pressure telltale illuminates, you
should stop and check your tires as soon as
possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated
tire causes the tire to overheat and can lead to
tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the
vehicle's handling and stopping ability.Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv-
er's responsibility to maintain correct tire pres-
sure, even if under-inflation has not reached
the level to trigger illumination of the TPMS low
tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the system
detects a malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups as
long as the malfunction exists. When the mal-
function indicator is illuminated, the system
may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may
occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one
or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires
and wheels allow the TPMS to continue to
function properly.

NOTE
•TPMS indicates low tire pressure but
does not replace normal tire mainte-
nance. For information on correct tire
pressure, please refer to the tables
beginning on page 181, or consult your
Volvo retailer.
•The tire pressure warning light will not
identify which tire is underinflated. Be
sure to check all four tires.
•A certain amount of air seepage from
the tires occurs naturally and tire pres-
sure fluctuates with seasonal changes
in temperature. Always check tire pres-
sure regularly.
Erasing warning messagesWhen a low tire pressure warning message has
been displayed, and the tire pressure warning
light has come on:
1. Use a tire pressure gauge to check the
inflation pressure of all four tires.
2. Re-inflate the tire(s) to the correct pressure
(consult the tire pressure placard or the
tables, see page 181 ).
3. In certain cases, it may be necessary to
drive the vehicle for several minutes at a
speed of 20 mph (30 km/h) or faster. Thiswill erase the warning text and the warning
light will go out.
WARNING
Incorrect inflation pressure could lead to tire
failure, resulting in a loss of control of the
vehicle.
Changing wheels with TPMSPlease note the following when changing or
replacing the factory installed TPMS wheels/
tires on the vehicle:
•Only the factory-mounted wheels are
equipped with TPMS sensors in the valves.
•If the vehicle is equipped with a temporary
spare tire, this tire does not have a TPMS
sensor.
•If wheels without TPMS sensors are moun-
ted on the vehicle, TIRE PRESS SYST
SERVICE REQUIRED will be displayed
each time the vehicle is driven above
25 mph (40 km/h) for 10 minutes or more.
•Once TPMS sensors are properly installed,
the warning message should not reappear.
If the message is still displayed, drive the
vehicle for several minutes at a speed of
20 mph (30 km/h) or faster to erase the
message.
•Volvo recommends that TPMS sensors be
fitted on all wheels used on the vehicle.Volvo does not recommend moving sen-
sors back and forth between sets of
wheels.
NOTE
•If you change to tires with a different
recommended inflation pressure, the
TPMS system must be recalibrated to
these tires. This must be done by an
authorized Volvo retailer or workshop.
•If a tire is changed, or if the TPMS sen-
sor is moved to another wheel, the sen-
sor's seal, nut, and valve core should be
replaced.
•When installing TPMS sensors, the
vehicle must be parked for at least
15 minutes with the ignition off. If the
vehicle is driven within 15 minutes, a
TPMS error message will be displayed.
CAUTION
When inflating tires with TPMS valves, press
the pump's mouthpiece straight onto the
valve to help avoid bending or otherwise
damaging the valve.
Recalibrating TPMS (Canadian models
only)
In certain cases, it may be necessary to reca-
librate TPMS to conform to Volvo's recom-

08 Car care
Washing and cleaning the car
08

207
Automatic washing – simple and quickWe do NOT recommend washing your car in an
automatic wash during the first few months
(because the paint will not have hardened suf-
ficiently).
An automatic wash is a simple and quick way
to clean your car, but it is worth remembering
that it may not be as thorough as when you
yourself go over the car with sponge and water.
Keeping the underbody clean is most impor-
tant, especially in the winter. Some automatic
washers do not have facilities for washing the
underbody.
CAUTION
•Before driving into an automatic car
wash, turn off the optional rain sensor to
avoid damaging the windshield wipers.
•Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them
•Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.
WARNING
•When the car is driven immediately after
being washed, apply the brakes several
times in order to remove any moisture
from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or taillights. This is nor-
mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and Waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
CAUTION
Volvo does not recommend the use of long-
life or durable paint protection coatings,
some of which may claim to prevent pitting,
fading, oxidation, etc. These coatings have
not been tested by Volvo for compatibility
with your vehicle's clear coat. Some of them
may cause the clear coat to soften, crack,
or cloud. Damage caused by application of
paint protection coatings may not be cov-
ered under your vehicle's paint warranty.
