General notes
The multimedia system section in this Opera-tor's Manual describes the basic principles foroperation. More information can be found inthe Digital Operator's Manual.
Important safety notes
GWARNING
If you operate information systems and com-
munication equipment integrated in the
vehicle when driving, you may be distracted
from the traffic situation. You could also
lose control of the vehicle. There is a risk of
an accident.
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 equipment when the vehicle is station-
ary.
You must observe the legal requirements forthe country in which you are currently drivingwhen operating the multimedia system.
The multimedia system calculates the route tothe destination without taking the followinginto account, for example:
Rtraffic lights
Rstop and yield signs
Rparking or stopping restrictions
Rroad narrowing
Rother road and traffic rules and regulations
The multimedia system may give incorrect nav-igation recommendations if the actual street/traffic situation does not correspond with thedigital map's data.
For example:
Ra diverted route
Rthe road layout or the direction of a one-waystreet has been changed
For this reason, you must always observe roadand traffic rules and regulations during yourjourney. Road and traffic rules and regulationsalways have priority over multimedia systemdriving recommendations.
Navigation announcements are intended todirect you while driving without diverting yourattention from the road and driving.
Please always use this feature instead of con-sulting the map display for directions. Lookingat the icons or map display can distract youfrom traffic conditions and driving, andincrease the risk of an accident.
This equipment complies with FCC radiationexposure limits set forth for uncontrolledequipment and meets the FCC radio frequency(RF) Exposure Guidelines in Supplement C toOET65.
This equipment has very low levels of RFenergy that is deemed to comply without maxi-mum permissive exposure evaluation (MPE).However, it is recommended to install it at adistance of at least 8 inches (approx. 20 cm)between the radiation source and a person'sbody (not including limbs such as hands,wrists, feet and legs).
GWARNING
Modifications to electronic components,
their software as well as wiring can impair
their function and/or the function of other
networked components. In particular, sys-
tems relevant to safety could also be affec-
ted. As a result, these may no longer func-
tion as intended and/or jeopardize the oper-
ating safety of the vehicle. There is an
increased risk of an accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop.
Function restrictions
For safety reasons, some functions are restric-ted or unavailable while the vehicle is inmotion. You will notice this, for example,because either you will not be able to selectcertain menu items or a message will appearto this effect.

The tire pressure monitor does not warn you ofan incorrectly set tire pressure. Observe thenotes on the recommended tire pressure(Ypage 307).
The tire pressure monitor is not able to warnyou of a sudden loss of pressure, e.g. if thetire is penetrated by a foreign object. In theevent of a sudden loss of pressure, bring thevehicle to a halt by braking carefully. Avoidabrupt steering movements.
The tire pressure monitor has a yellow warninglamp in the instrument cluster for indicatingpressure loss or a malfunction. Whether thewarning lamp flashes or lights up indicateswhether a tire pressure is too low or the tirepressure monitor is malfunctioning:
Rif the warning lamp is lit continuously, thetire pressure on one or more tires is signifi-cantly too low. The tire pressure monitor isnot malfunctioning.
Rif the warning lamp flashes for around aminute and then remains lit constantly, thetire pressure monitor is malfunctioning.
In addition to the warning lamp, a messageappears in the multifunction display. Observethe information on display messages(Ypage 223).
It may take up to ten minutes for a malfunc-tion of the tire pressure monitor to be indica-ted. A malfunction will be indicated by the tirepressure warning lamp flashing for approx-imately one minute and then remaining lit.When the malfunction has been rectified, thetire pressure warning lamp goes out after afew minutes of driving.
The tire pressure values indicated by the on-board computer may differ from those meas-ured at a gas station with a pressure gauge.The tire pressures shown by the on-boardcomputer refer to those measured at sea level.At high altitudes, the tire pressure values indi-cated by a pressure gauge are higher thanthose shown by the on-board computer. In thiscase, do not reduce the tire pressures.
The operation of the tire pressure monitor canbe affected by interference from radio trans-mitting equipment (e.g. radio headphones,two-way radios) that may be being operated inor near the vehicle.

Instruction labels for tires and loads
GWARNING
Overloaded tires can overheat, causing a
blowout. Overloaded tires can also impair
the steering and driving characteristics and
lead to brake failure. There is a risk of acci-
dent.
Observe the load rating of the tires. The load
rating must be at least half of the GAWR of
your vehicle. Never overload the tires by
exceeding the maximum load.
Two instruction labels on your vehicle showthe maximum possible load.
(1) The Tire and Loading Information placardis on the B-pillar on the driver's side. TheTire and Loading Information placardshows the maximum permissible numberof occupants and the maximum permissi-ble vehicle load. It also contains details ofthe tire sizes and corresponding pressuresfor tires mounted at the factory.
(2) The vehicle identification plate is on the B-pillar on the driver's side. The vehicleidentification plate informs you of thegross vehicle weight rating. It is made upof the vehicle weight, all vehicle occu-pants, the fuel and the cargo. You can alsofind information about the maximum grossaxle weight rating on the front and rearaxle.
The maximum gross axle weight rating isthe maximum weight that can be carriedby one axle (front or rear axle). Neverexceed the maximum load or the maxi-mum gross axle weight rating for the frontor rear axle.
