General notes
The multimedia system section in this Opera-
tor's Manualdescribes the basicp rinciples for
operation. More information can be found in the Digital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
municatio nequipment integrated in the vehi-
cle when driving, you may be distracted from
the traffic situation. You could also lose con-
trol of the vehicle.T here isarisk of an acci-
dent.
Only operate this equipment when the traffic
situation permits. If you are not sure that this
is possible, park the vehicle paying attention
to traffic conditions and operate the equip-
ment when the vehicle is stationary.
You must observe the legalr equirements for the
country in which you are currently driving when
operating the multimedia system.
The multimedia system calculates the route to
the destination withoutt aking the following into
account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rule sand regulations
The multimedia system may give incorrect nav-
igation recommendations if the actual street/
traffic situation does not correspond with the
digital map's data.
For example:
Rad iverted route
Rthe road layout or the direction of aone-way
street has been changed
For this reason, you must alwayso bserve road
and traffic rule sand regulations during your
journey. Roa dand traffic rule sand regulations
alwaysh ave priority over multimedia system
driving recommendations. Navigation announcements are intended to
direct you whiled
riving withoutdiverting your
attention from the road and driving.
Please alwaysu se this feature instead of con-
sulting the map display for directions. Looking
at the icons or map display can distract you from
traffic conditions and driving, and increase the
risk of an accident.
This equipment complies with FCC radiation
exposure limits set forth for uncontrolled equip-
ment and meets the FCC radiof requency (RF)
Exposure Guidelines in Supplement CtoOET65.
This equipment has very low levelsofRFe nergy
that is deemedtoc omply withoutmaximum
permissive exposure evaluation (MPE). How-
ever, it is recommended to insta

ll it atadistance
of at least 8inches (approx. 20 cm) betweent he
radiation source and aperson's body (not
including limbss uch as hands, wrists, feet and
legs).
GWARNING
Modifications to electronic components, their software as wellasw iring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle.T here is an increasedr isk of an
accident and injury.
Never tamper with the wiring as wellase lec-
tronic components or their software .You

Problems when programming
If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take not eofthe following instruc-
tions:
RCheck the transmitter frequenc yused by
garage door drive remotec ontrolAand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remotec ontrolAfor the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequenc yrange of 280 to
433 MHz.
RReplace the batteries in garage door remote
control A.This increases the likelihood that
garage door remotec ontrolAwill transmit a
stron gand precise signal to the integrated
garage door opener.
RWhen programming, hold remotec ontrolA
at varying distances and angles from but-
tons ;to? which you are programming. Try
various angles at adistanc ebetween 2and
8i nches (5to 20 cm) or at the same angle but
at varying distances.
RIf another remotec ontrolAis available for
the same garage door drive, repeat the same
programmings teps with this remotec ontrol
A.B eforep erforming these steps, make sure
that new batteries have been installed in
garage door drive remotec ontrolA.
RNote that some remotec ontrols only transmit
for alimited amount of time (the indicator
lamp on t
he remotec
ontrol goes out). Press button
Bon remotec ontrolAagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performst he function of the
garage door system remotec ontrol. Please also
read the operating instruction sfor the garage

the "Checking the tire pressure electronically"
section (
Ypage 296).
Important safety notes
GWARNING
Each tire, including the spare (if provided),
should be checked at least once every two
weeks when cold and inflated to the pressure recommended by the vehicle manufacturer
on the Tire and Loading Information placard
on the driver's door B-pillar or the tire pres-
sure label on the inside of the fuel filler flap. If
your vehicle has tires of adifferent size than
the size indicated on the Tire and Loading
Information placard or, if available, the tire
pressure label,y ou should determine the
proper tire pressure for those tires.
As an added safety feature, your vehicle has
been equipped with atire pressure monitoring
system (TPMS) that illuminates alow tire pres-
sure telltale when one or more of your tires
are significantly underinflated. Accordingly,
when the low tire pressure telltale lights up,
you should stop and check your tires as soon
as possible,a nd inflate them to the proper
pressure. Driving on asignificantly underin-
flated tire causes the tire to overheat and can
lead to tire failure.
Underinflation 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 asubstitute for proper tire
maintenance, and it is the driver's responsi-
bility to maintain correct tire pressure, even if
underinflation has not reached the level to
trigger illumination of the TPMS low tire pres- sure 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 sys-
tem detects amalfunction, the warning lamp
will flash for approximately aminute and then
remain continuously illuminated. This
sequence will be repeated every time the vehi-
cle is started as long as the malfunction
exists. When the malfunction indicator is illu-
minated, the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for avariety of
reasons, including the installation of incom-
patible replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioningp roperly. 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.
It is the driver's responsibility to set the tire
pressure to that recommended for cold tires
which is suitable for the operating situation
(
Ypage 290). Note that the correct tire pressure
for the current operating situation must first be
taught-in to the tire pressure monitor. If asub-
stantial loss of pressure occurs, the warning
threshold for the warning message is aligned to
the taught-in reference values. Restart the tire
pressure monitor after adjusting the pressure of
the cold tires (
Ypage 297). The current pres-
sures are saved as new reference values. As a
result, awarning message will appearift he tire
pressure drops significantly.
The tire pressure monitor does not warn you of
an incorrectly set tire pressure. Observe the
notes on the recommended tire pressure
(
Ypage 290).
The tire pressure monitor is not able to warn you
of as udden loss of pressure, e.g. if the tire is
penetrated by aforeign object. In the event of a
sudden loss of pressure, bring the vehicle to a
halt by braking carefully.A void abrupt steering
movements.
