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-

Introduction
Display when the radio is receiving an HD Radio
broadcast
HD radio is a brand name registered by the
Ibiquity digital corporation2. They are the
developer of a broadcasting technology called
IBOC or In Band On Channel, which refers to
the method of transmitting a digital radio
broadcast signal centered on the same fre-
quency as the AM or FM station's present fre-
quency.The IBOC system is referred to as a "hybrid"
since it is both analogue and digital. During
hybrid operation, receivers still continue to
receive the analogue (non-digital) signal. HD
radio receivers incorporate both modes of
reception, where the receiver will automatically
switch to the analogue signal if the digital signal
cannot be decoded or is lost by the receiver.
When you have tuned to an HD Radio station,
the
symbol will appear in the audio sys-
tem display.
More information about HD radio and IBOC
can be found on Ibiquity's website,
www.hdradio.com and www.ibiquity.com.
Benefits of digital broadcasting
•Better sound (FM sounds near CD quality
and AM as analogue FM).
•Some FM frequencies offer a greater num-
ber of listening choices through “multicast-
ing” (consisting of a frequency's main
channel and any sub-channels that may
also be available on that particular fre-
quency. See also the section "Sub-chan-
nels" below).
•When receiving a digital signal there is no
multipath disturbance or hisses/pops/
crackling due to outside influences.
How HD broadcasting worksHD Radio works similarly to conventional radio
and broadcasts of this type are available in
many areas of the United States. However,
there are a few key differences:
•Instead of transmitting one analogue sig-
nal, stations send out a bundled signal –
both analogue and digital.
•An HD radio receiver can receive both dig-
ital and analogue broadcasts. Depending
on the terrain and location of the vehicle
(which will influence the signal strength),
the receiver will determine which signal to
receive.
Limitations
•Main channel vs. sub-channels (FM
only): The main channel is the only channel
that can receive in hybrid mode (both dig-
ital and analogue). If a frequency has sub-
channels, they are broadcast in digital
mode only. The main FM channel will be
displayed as, for example, 93.9 WNYC
(Volvo uses the symbol > to indicate there
are sub-channels available) The sub-FM

channels will be displayed as 93.9 – 2
WNYC, 93.9 - 3 WNYC, etc.
•Reception coverage area: Due to current
IBOC transmitter power limitations, the
reception coverage area in digital mode is
somewhat more limited than the station's
analogue coverage area. Please be aware
that as with any radio broadcast technol-
ogy, terrain, time of day, foliage level and
building location can have positive or neg-
ative effects on radio reception.
•Analogue to digital/digital to analogue
blending: Analogue to digital blending will
occur as the signal strength reaches a pre-
set threshold in the receiver. This will be
noticeable in fringe areas (areas with weak
reception) and is normal.
NOTE
There may be a noticeable difference in
sound quality when a change from analogue
to digital or digital to analogue occurs, such
as:
•Volume increase or decrease
•Equalizer settings, i.e., Bass/ Midrange/
Treble cut or boost
•Time alignment (Digital program mate-
rial in extreme cases can be as much as
8 seconds behind the analogue). This
will noticeable as a "stuttering" effect.
The above items are dependant on the
broadcaster's equipment settings and do
not indicate a fault in the vehicle's radio
receiver or antenna systems.
Switching HD on or offThe factory setting for HD radio is on. However,
when driving through areas with weak HD sig-
nals (fringe areas), you may experience that the
radio repeatedly switches between analogue/
digital and digital/analogue reception. If this
happens, it may be desirable to switch HD off.
To do so:
1. Be sure the audio system is switched on
and is in AM or FM mode.
2.
Press MENU in the center console control
panel.3.
Press ENTER to turn HD off (the X will dis-
appear from the box on the display screen).
This will disable the radio's capability to receive
digital broadcasts but it will continue to func-
tion as a conventional (analogue) AM/FM
receiver. Please note that when HD is switched
off, it will not be possible to tune to sub-chan-
nels (see the following section for a more
detailed explanation of sub-channels).
Repeat steps 2 and 3 above to reactivate HD
(an X will appear in the box on the display
screen).

In many cases, a main HD Radio station (FM
wavebands only) will also have sub-channels
offering additional types of programming or
music.
In such cases, a number will be displayed to
the right of the frequency number indicating
that the currently tuned frequency has at least
one sub-channel. The "2" in the illustration indi-
cates that you are currently listening to the first
sub-channel on frequency 93.9.
Selecting sub-channelsTo listen to a station's sub-channel(s), press
the right arrow key on the center console or on
the steering wheel keypad. To go back to the
main channel, press the left arrow key. To go
to subchannel 2 (if available), press the right
arrow key.
If you are currently tuned to a frequency's main
channel, pressing the left arrow key will tune to
the next lower radio frequency.
NOTE
•When the radio has gone into HD mode,
it may take several seconds before the
">" symbol (if the current frequency has
any sub-channels) is displayed to the
right of the frequency. Pressing the
arrow keys before the number is dis-
played will cause the radio to tune to the
next available radio station, not to the
current station's sub-channels.
•When you are no longer in broadcasting
range of the currently tuned sub-chan-
nel,
No HD reception will be dis-
played. The radio will then be muted
and it will be necessary to tune to or
search for a new radio station.
Sub-channels can also be stored as presets,
see page 248 for information on storing sta-
tions.
If you press a sub-channel's preset button, it
may take up to 6 seconds before the channel
becomes audible. If you press this button while
you are out of digital range of the transmitter,
No HD reception will be displayed.
Listening to satellite radio
The Sirius satellite system consists of a number
of high elevation satellites in geosynchronous
orbit.
NOTE
•The digital signals from the Sirius satel-
lites are line-of-sight, which means that
physical obstructions such as bridges,
tunnels, etc, may temporarily interfere
with signal reception.
•Avoid any obstructions, such as metal-
lic objects transported on roof racks or
in a ski box, or other antennas that may
impede signals from the SIRIUS satel-
lites.
Selecting Sirius radio mode1. Press Power to switch on the audio system
(see page 248 for information on the stand-
ard radio functions).
2.
Press the MODE button repeatedly until
Sirius 1 or 2 is displayed.
Activating Sirius radio1. Tune to a satellite channel that has no
audio, which means that the channel is
unsubscribed and the text "

•CDR discs can cause listening problems
due to the quality of the disc or recording
equipment used.
•DualDisc: The audio side of a DualDisc
(combined CD/DVD) does not meet CD
specifications and may not play in your
audio system.
•Keep the discs clean. Wipe them with a
soft, clean, lint-free cloth, working from the
center outward. If necessary, dampen the
cloth with a neutral soap solution. Dry thor-
oughly before using.
•Never use cleaning spray or antistatic liq-
uid. Use only cleaners specifically made for
CDs.
•Use discs of the correct size only
(3.5" discs should never be used).
•Volvo does not recommend the use of
plastic outer rings on the disc.
•Condensation may occur on discs/optical
components of the CD player in cold winter
weather. The disc can be dried with a
clean, lint-free cloth. Optical components
in the CD player may, however, take up to
one hour to dry off.
