Exhaust system on vehicles with 3.0l V6 TDI Biturbo engine

Oxygen sensor G39

Oxidising catalytic converter

Sound actuator

The sound actuator system consists of a signal generator, a signal ampliﬁ er and an exciter1). Stored on the structural vibration control unit J869 there are various sound ﬁ les which can be played and transmitted to the exciter according to vehicle model and operating data (engine speed and load, vehicle speed).

Exhaust gas temperature sender 2 G448

Exhaust gas temperature sender 1 G235

Exhaust gas temperature sender 3 G495

Diﬀ erential pressure sensor G505

Exhaust temperature sensor 4 for cylinder bank 2, G649

Diesel particulate ﬁ lter

Exhaust gas temperature sender 4 G648

The exciter generates the structure borne noise. That is then

carried into the passenger compartment through the bodywork and the windscreen. The exciter is ﬁ tted centrally to the base of the windscreen by means of a special ﬁ xing; it is the system's "tuning fork".

Diﬀ erent models and engines require diﬀ erent excitation to create a balanced engine note. The information about the engine ﬁ tted and the body type is read from the CAN data bus (Powertrain CAN). The structural vibration control unit J869 automatically detects in which vehicle it is ﬁ tted.

An exciter, also called a structural vibration converter or bodyshaker, is basically a speaker without a speaker cone. That function is performed by the windscreen, which directs the sound into the vehicle interior. It consists essentially of three components: the vibrating mass, the socket for electrical connection to the structural vibration control unit J869, and the mounting bolt for ﬁ xing it to the mounting surface.

Reference

More information on the sound actuator system can be found in Self-study Programme 491, "Audi 1.4l TFSI Engine with Twin Turbochargers".

Active-sound exhaust system

The active-sound exhaust system comprises an exhaust system with attached speaker housings, an engine noise generation control unit, J493, and the actuators R257 and R258 that are operated by the control unit. The control unit receives vehicle data (engine speed, engine load, vehicle model, road speed) from the CAN bus (Powertrain CAN). The actuators generate sound waves according to the data-map based control unit commands. The sound module is formed by additional speaker housings on the main silencers, which connect directly to the tailpipes. The signal generator, which is ﬁ tted in the engine noise generation control unit J943, produces a range of vibrations dependent on the engine operating mode. That signal spectrum is ampliﬁ ed into a power signal by the engine noise generation control unit J943 and converted into sound waves by the actuator.

The active sound system is capable of generating certain frequencies (engine harmonics) in order to produce a desired sound pattern (sound design). In contrast with conventional exhaust systems with passive silencers, the exhaust sound can be adapted to the vehicle and the driving situation via Audi drive select.

Note

On vehicles with an active-sound exhaust system, the tailpipes must not be sealed over to test for leaks or be pressurised

with compressed air as doing so could destroy the speaker diaphragms.

Power transmission

Overview

The Audi A6Avant'12 is another model in the C7 series on which the power transmission concept with the forward-shifted diﬀ erential from the B8 series is used. Other features of the concept are the method of connecting the prop shaft to the gearbox and the rear diﬀ erential and various weight-saving measures (see reference below).

Dynamic handling is assisted by independently selective wheel torque control. Information on this can be found in SSP 478 and the Audi iTV programme "Audi RS5 Power Transmission Part 2" of 23/09/2010.

The automatic transmissions are incorporated in the engine's innovative temperature management system. It controls the ATF operating temperature and thus increases its eﬃ ciency. For information on the innovative temperature management system, please refer to SSP 486.

With the automatic transmissions, use of the navigation system's predictive

route data is possible, see SSP 457.

603_089

multitronic 0AW

multitronic 0AW is available for vehicles with front-wheel drive. A sports program and a tiptronic mode with eight ﬁ xed transmission ratios provide for a sports-style driving experience. These can be changed with the paddles on the steering wheel or with the selector lever. The start-stop system is supported as standard. The clutch pressure supply system, the hydraulic control unit and the gearbox software have been optimised for this purpose.

The 0AW multitronic gearbox will be combined with the following engines:

• 2.0l R4 TFSI engine

• 2.0l R4 TDI engine

• 2.8l V6 FSI engine

• 3.0l V6 TDI engine

Rear-axle transmission

Standard:

Rear axle diﬀ erential 0BC

Optional:

Rear axle drive 0BF with sport diﬀ erential for:

• 3.0l V6 TFSI engine

• 3.0l V6 TDI engine

More information on the 0BF sports diﬀ erential can be found in the iTV tutorial "Audi quattro with Sports Diﬀ erential" Parts 1, 2, 3 and 4, and in SSP 476 "Rear Diﬀ erential 0BF/0BE Sports Diﬀ erential."

Reference

The power transmission concept used on the B8 series (Type 8K/8T/8F) was carried over to the C7 series (Type 4G-) on introduction of the Audi A7 Sportback. Information on this can be found in SSP 392 and 409 and the Audi iTV programme "Audi A5 Power Transmission Part " of 23/02/2010. Information on the "socket-mount prop shaft" can be found in SSP 478 and the Audi iTV programme "Audi A8 Power Transmission Part 2" of 02/09/2010. That information also applies to the AudiA6 Avant'12 and forms the basic knowledge on those topics.

Stronic 7-speed double-clutch transmission 0B5

The 7-speed double-clutch gearbox was ﬁ rst introduced in 2008 on the Audi Q8. This is explained in detail in SSP 429. The gearbox used on the Audi A6Avant'12 is the same as the one on the version of the AudiA7Sportback described in SSP 478. The startstop system is now supported as standard. The software has been optimised for that purpose.

The 0B5 S tronic 7-speed manual gearbox is paired with the following engines:

• 2.8l V6 FSI engine

• 3.0l V6 TFSI engine

• 3.0l V6 TDI engine

8-speed automatic transmission 0BK

The 0BK 8-speed automatic transmission is used in combination with engines that are capable of delivering torque levels over 550Nm. The start-stop system is supported by means of a hydraulic pressure accumulator. Details of it can be obtained from SSP 457.

603_091

603_090

603_092

6-speed manual gearbox 0B1

The 0B1 six-peed manual gearbox is used with engines with a torque rating of up to 400Nm. The start-stop system is supported as standard. The gear detection sensor G604 that the system requires is described in SSP 486 "AudiA6'11".

The 0BK 8-speed automatic transmission is used together with the following engine:

• 3.0l V6 TDI Biturbo engine

The 6-speed manual gearbox 0B1 is combined with the following engines:

• 2.0l R4 TFSI engine

• 2.0l R4 TDI engine

• 2.8l V6 FSI engine

• 3.0l V6 TDI engine

8-speed automatic transmission 0BK

The 0BK transmission has been familiar since the launch of the Audi A8'10 (Series D4) and is described in SSP 457. In the C7 series it is used in combination with the engines with a maximum torque of over 550Nm.

One diﬀ erence from the AudiA8'10 is that the gearbox is not operated using the "shift by wire" technology. The selector lever positions are communicated to the transmission by conventional means using a selector cable. That operates the gear sensor G676 via the shift lever, the gearshift actuator and, by purely mechanical means, the parking lock.

Selector lever cable

Selector mechanism

The selector mechanism on the Audi A6 Avant'12 is largely the same as that used from model year 2006 on the AudiA6'05. The same mechanism can also be found on the AudiA4, AudiA5 and AudiQ5 from model year 2008 and on the Audi A7Sportback. A detailed description can be found in SSP 409 starting on page 34.

There is a diﬀ erence from the selector mechanism described in SSP 409 in terms of the operating logic. Changing transmission mode from D to S (or from S to D) is eﬀ ected by pressing the selector lever backwards once from the position D/S. Afterwards, the selector lever always springs back to the position D/S. This operating logic is identical to that on the AudiA6'11 and the AudiA7Sportback.

Shift lever

603_094

When the lever is pressed backwards from position D/S, the selector lever sensor J587 sends the sports-mode toggle signal to the transmission control unit. In response, the system switches to sports mode or back to normal drive mode D, see Figure 603_097

Mechatronics (E26/4)

The mechatronic technology (E26/4) is extensively explained by the description of the mechatronics (E26/6) in Self-study Programme 457 "AudiA8'10 Power Transmission". The use of a selector lever cable instead of the "shift by wire" technology involves the following changes:

• The parking lock is operated by the selector lever cable.

• Solenoid valve N88 has no function within the mechatronic

system.

• Selector lever positions P, R, N and D are detected by the gear

sensor G676.

• The gearshift actuator controls the hydraulic pressure to the

hydraulic valves and ensures the neutral position.

The sensor is part oﬀ the electronic module and is operated by the shift lever. A magnet in the sensor's sliding block switches four Hall-eﬀ ect sensors (A/B/C/D) according to the selector lever position. The signals from the Hall-eﬀ ect sensors are analysed and thus provide the transmission control unit with information about selector lever positions P, R, N and D.

Changing from D to S or S to D is signalled to the transmission control unit by the selector lever sensor J587, see page 27.

Gearshift actuator

The gearshift actuator is operated by the shift lever. In transmission modes R, D and S it controls the hydraulic pressure to the valves and depressurisation in transmission modes N and P.

Virtual pedal

Introduction

The AudiA6Avant'12 is the ﬁ rst Audi model to oﬀ er the new "virtual pedal" function.

The virtual pedal enables automatic opening of the tailgate without having to touch a control on the vehicle or take the vehicle key out of your pocket. Automatic opening of the tailgate is initiated by a kicking action with your foot under the rear bumper.

The virtual pedal represents a substantial gain in user convenience, for example if someone wants to open the tailgate when their hands are full with shopping bags.

Electrical design and components

To identify a kicking action, two electrodes are ﬁ tted in the rear bumper trim. They work as capacitive sensors.

The A6Avant'12 is automatically equipped with the virtual pedal if the following optional equipment is ﬁ tted:

• Advanced key and

• Electrically operated tailgate

The optional Advanced Key is required to identify an authorised vehicle key after the kicking action is performed. The key must be within the area surrounding the tailgate.

The electrically operated tailgate option ensures that the tailgate opens fully after the kicking action is performed.

The two electrodes are connected to the tailgate opening control unit J938. The control unit J938 is a LIN slave of the comfort/ convenience systems control unit J393.

Detection of kicking action using two electrodes

The kicking action oﬀ the foot is detected by two capacitive sensors the signals from which are read by the tailgate opening control unit J938. The tailgate opening control unit continuously measures the capacitance of the two sensors. A capacitive sensor is a capacitor, which is a component consisting of two capacitor plates. In this case, each of the sensor electrodes forms one capacitor plate. The ground on which the vehicle is standing forms the second capacitor plate. When the capacitor is charged, there is an electrical ﬁ eld between the two plates.

The capacitance of a capacitor depends substantially on the medium that is between the two capacitor plates. In electrical engineering, that medium is called the dielectric. In the case of the virtual pedal, the medium concerned is air. If someone moves their foot between the two capacitor plates, the medium between the plates changes and, consequently, the capacitance of the capacitor. That change in capacitance is detected by the tailgate opening control unit J938 by continuous measurement.

Terminal 30

Someone moving their foot under the bumper ﬁ rstly causes the capacitance of the ﬁ rst capacitive sensor (Electrode 1) to increase. Then the capacitance of the second capacitive sensor (Electrode 2) increases as well. As soon as the person withdraws his/her foot, the capacitance of the second sensor drops back to its original level. The same then happens with capacitive sensor 1.

The kicking action must be ﬁ t within a speciﬁ ed time frame. The time frame is used to distinguish the kicking action of a foot from other motion sequences. If the kicking action is performed too slowly or too quickly, the system will not initiate a scan for a vehicle key and the tailgate will not be opened.

The sequence is described for an AudiA6Avant'12. The vehicle's ignition is switched oﬀ and the tailgate is closed.

1. A kicking action is performed below the rear bumper.

2. The tailgate opening control unit J938 detects the kicking action by means of its two electrodes and sends the information to the comfort/convenience systems control unit J393.

3. The comfort/convenience systems control unit starts a key scan using its keyless aerials.

4. The vehicle key receives the signals from the various aerials and sends a message to the comfort/convenience systems control unit J393.

5. Control unit J393 receives the message via the central locking aerial R47.

6. Control unit J393 analyses the message and detects that there is an authorised key in the vicinity of the vehicle rear.

7. Control unit J393 operates the motor V120 for unlocking and opening the tailgate.

8. Control unit J393 sends a CAN message instructing the tailgate control unit J605 to open the tailgate.

9. Control unit J605 operates its two electric motors V444 and V445 and opens the tailgate.

Exterior lighting

Headlight

On the AudiA6Avant'12, the same headlight options are oﬀ ered as on the AudiA6'11.

• Halogen headlights

• Bi-xenon headlights

• LED headlights

Information on the headlights, the light functions and headlight beam height adjustment can be found in SSP 486, AudiA6'11.

Tail lights

603_073

The tail light clusters on the AudiA6Avant'12 basically come in two versions.

• Basic tail light cluster

• LED tail light cluster

Basic tail light cluster

The three 21-watt bulbs in the top section of the tail light clusters are used for the tail lights and the brake lights on the AudiA6Avant'12.

Tail/brake light (P21W)

They are made up of two parts on each side of the vehicle. One half of the light cluster is incorporated in the side panel and the other half in the tailgate.

That distinguishes the A6Avant'12 from the A6'11 on which only one 21-watt bulb (in the side-panel light) was used for the brake light. When the rear fog light is on, the centre bulb on the AudiA6Avant'12 is only used for the tail light function.

LED tail light cluster

The LED taillight clusters on the A6Avant'12 are very similar to those on the A6'11. All functions are implemented by means of LED technology. The only exception is the reversing light (one 16-watt bulb on each side of the vehicle). On the A6Avant'12, those 16-watt bulbs are housed in the tailgate lights. By comparison: On the A6'11, the reversing light and the rear fog light comprise one bulb each on each side of the vehicle and the reversing light is housed in the side panel lights.

Brake light

The third brake light is integrated in the rear spoiler, assists brake light function by means of 18 LEDs and is controlled by the central

comfort/convenience systems control unit J393. Individual components of the third brake light cannot be replaced. If it fails, the item must be replaced as a complete unit, which requires removal of the rear spoiler.

Number plate light

With the launch of the A6Avant'12, the number plate lights with 5-watt bulbs have been discontinued and replaced by a number plate light that uses LED technology. It is now ﬁ tted on all C7series models regardless of tail-light version. The two number plate lights are clipped into the tailgate panel, each have two LEDs, and, like the taillights, are operated by the central comfort/convenience systems control unit J393.

Air conditioning

Overview

The air conditioning systems on the AudiA6Avant'12 heat, cool and dehumidify the air in the vehicle interior. They are based on the air conditioning systems on the AudiA6'11.

The AudiA6Avant'12 is oﬀ ered with two diﬀ erent air conditioning systems – automatic climate control and enhanced automatic climate control.

Automatic climate control Enhanced automatic climate control

Equipment and technical details of enhanced automatic climate control

• Four climate control zones

• Two A/C control panels

• Full key recognition

• Automatic mode

• Automatic air recirculation

• Rear window heater

• Seat heating with three settings (option)

• Seat ventilation with three settings (option)

• A/C modes

• Residual heat function

• Synchronisation of all four climate control zones

603_084

A/C modes

The power of the air ﬂ ow can be set to gentle/"eco", "medium" and "intensive". The "eco" setting sets the automatic climate control to an economy-orientated mode. In eﬃ ciency driving mode, the A/C mode "eco" is automatically selected. However, it is possible to manually deselect "eco" mode when eﬃ ciency mode is active. For example, the customer can switch to A/C mode "medium". When doing so, all other eﬃ ciency settings remain active.

eﬃ ciency mode

On the Audi A6Avant'12, the customer can select eﬃ ciency mode via Audi drive select on the MMI. That sets the air conditioning system to an operating mode optimised for economical fuel consumption and the A/C mode "eco" is automatically activated. When A/C mode "eco" is activated, the air conditioning system switches to a range optimised for low-energy consumption within temperature thresholds that are acceptable for the vehicle occupants.

Systems

The air conditioning system operates at reduced output. Within the temperature limits of approx. –5°C to +20°C, the system attempts to achieve the interior temperature desired by the vehicle occupant without resorting to the supplementary heater or with the supplementary heater at reduced output, or as the case may be, at reduced compressor output or with the compressor switched oﬀ altogether.

The auxiliary heater/ventilation heats and ventilates the vehicle interior and can be switched on when the engine is switched oﬀ as well as when the vehicle is being driven. The auxiliary heater is made by Eberspächer and is based on the Eberspächer HydronicII model.

Setting options

Option1: Switching on/oﬀ immediately

The auxiliary heater/ventilation can be switched on/oﬀ immediately. The vehicle switches the auxiliary heater or ventilation on depending on the ambient temperature and the temperature setting.

Fault messages

In the event of a fault, various fault symbols may be displayed when the remote control is switched on.

Symbol Meaning

There is a system fault on the auxiliary heater. The fault can be localised and rectiﬁ ed by an Audi service agent.

The same auxiliary heater is used on various Audi models such as the Audi A8'10 and the B8 series (e.g. Audi A4'08).

Option2: Setting the timer

The remote control can be used to set a timer and so program a time by which the vehicle is to have reached the desired temperature. The remote control can only be used to program Timer1. The system decides when to switch on the auxiliary heater or ventilation based on the set temperature and the ambient temperature. Three diﬀ erent timers can be activated via the MMI.

Display area for fault symbols.

The auxiliary heater cannot be switched on because there is insuﬃ cient fuel.

The auxiliary heater cannot be switched on because the charge level of the vehicle battery is too low.

The vehicle is outside the range of the remote control.

603_081

Note

Despite the auxiliary heaters being identical, a remote control for an Audi A6Avant'12 cannot be taught to work with an Audi A4'08 auxiliary heater. Nor is the reverse possible.

MMI Navigation (RMC)

The information/entertainment system MMI Navigation oﬀ ers the navigation function in addition to the MMI Radio functions. The navigation map data is stored on an SD card. For Europe, for example, it is an 8-GB SDHC card. Navigation is only possible with the map data SD card inserted.

The navigation system has a two-dimensional map display. It can also show the map in bird's-eye view. To do so, the setting must be changed to 3D map. Other highlights of the navigation system include manoeuvre lists and detailed intersection maps. The information is shown on the display using the split-screen method.

Voice interactive system (RMC)

The voice interactive system supports various languages. In order to set the desired language a separate language CD was required in the past with the Radio Media Center. It had to be inserted in the electronic information systems control unit 1, J794, in order to upload the language data. To simplify that process, the current RMC electronic information systems control unit 1, J794, has a larger internal memory. It already has the languages for the relevant sales region stored on it. Changing the language now takes place automatically after the relevant MMI menu option is selected and applies to the display language and the voice interactive system.

Diﬀ erent languages are stored according to sales region. The following languages are supported in the North America region, for example:

Note

The MMI must be set to the normal language for the country during the hand-over service.

New features of RMC DAB radio tuner

The function "digital radio tuner" oﬀ ered with RMC systems now supports the following standards:

• DAB

• DAB+

• DAB+DMB Audio (Digital Multimedia Broadcasting)

DAB+ and DMB Audio are extended versions of the DAB standard. These technologies enable the transmission of more radio stations with supplementary data (e.g. traﬃ c information) due to greater audio compression compared with DAB. Therefore, DAB+ and DMB Audio enable more radio stations/station components within a channel (ensemble) and thus more eﬃ cient use of resources.

New features of MMI Navigation plus with web-enabled Bluetooth car phone

Audi online traﬃ c information (in some parts of Europe)

With the MMI Navigation plus with the optional web-enabled Bluetooth car phone, not only does the navigation map show

traﬃ c information but on many roads the actual current traﬃ c ﬂ ow is also indicated. That makes computing the route and arrival time more reliable.

Google online search using voice interactive system (some parts of Europe)

The voice interactive system of the MMI Navigation plus with web-enabled Bluetooth car phone has been extended by an additional input facility. Using the voice command "Online destinations" it is now possible to search for any destination without taking your hands oﬀ the steering wheel. This is an extension of the input facility for the existing online destination search that currently uses Google on the internet.

Access to mobile phone address book when Bluetooth car phone is active

When using the Bluetooth car phone, the phone numbers from the SIM card inserted1) can still be used. A new addition is the ability to use the address book of a mobile phone connected via Bluetooth.

Audi online traﬃ c information (in some parts of Europe)

Getting to your destination quickly taking the shortest route possible and not using fuel unnecessarily – those are probably the most important criteria placed on a navigation system by any user. With the new Audi online traﬃ c information function, Audi meets that demand better than ever.

In the past, traﬃ c information was mainly communicated via radio stations, which involved technically related limitations regarding the transmission speed and the maximum number of bulletins. In addition, the immediacy and accuracy of the reports sometimes left something to be desired. Another disadvantage was that cross-border information was only available to a limited degree. The eﬀ ect was that, for instance, the dynamic route guidance might direct the vehicle almost right up to the location of a traﬃ c hold up before changing route. And that could mean a major detour. However, if the relevant information is available at the start of the journey, a more suitable route can be worked out from the outset.

With the introduction of Audi online traﬃ c information, the driver has access to extremely up-to-date traﬃ c reports which can also be supplemented by traﬃ c ﬂ ow data. In order to enable easy orientation for the driver, the electronic information systems control unit 1, J794, converts the information into coloured lines shown alongside the relevant roads on the map. When route guidance is active, that data is taken into account for route computation. For that purpose, a data connection to the server is established via the internal telephone module and the data transferred from the internet in encrypted form.

Where does the traﬃ c ﬂ ow data come from?

The data for calculating the traﬃ c ﬂ ow is generated from a large number of navigation devices and applications (mobile navigation devices, smartphones, etc.) that are in vehicles. Such devices cyclically transmit their current location and speed of travel. The

transmission of such data is entirely anonymous – no personal data is sent. In addition, data from a variety of ﬂ eet management systems is included in the computations.

What other data is used?

In addition to the traﬃ c ﬂ ow data, reports and traﬃ c bulletins from a large variety of public and private sources are used.

Destination

Cross-border display of traﬃ c information

Who produces that data?

The traﬃ c data for Audi online traﬃ c information is collated and prepared by INRIX. INRIX receives data from several million terminal devices for that purpose. In order to provide every vehicle with the data relevant to route guidance, the reports are prepared individually for every vehicle and transmitted to it on the basis of location, route and destination.

Settings

603_046

Note Audi online traﬃ c information is automatically available if the optional equipment MMI Navigation plus and web-enabled

Bluetooth car phone are ﬁ tted. On market launch of the AudiA6Avant'12, the function will be available in Belgium, Germany, France, Italy, the Netherlands, Austria and Switzerland.

How is the data displayed in the vehicle?

The way in which the data is displayed is designed to distract the driver as little as possible. Therefore, a visual representation based on the use of four colours has been chosen. The colours have been chosen so that the driver can understand their meaning without studying the instruction manual. If there is a traﬃ c report available that applies to a section of road, all the lines regardless of colour are hatched for the length of the section aﬀ ected by the traﬃ c incident.

What data does the vehicle receive?

A vehicle receives data according to location. As it moves further away from a location, the data volume gradually decreases. Roughly, the data density is divided into three circles:

• Inner circle: all available data, regardless of road type

• Middle circle: all data relating to motorways and major roads

• Outer circle: only danger warnings and road closures

In addition, the following data is shown when route guidance is active:

• All available data along the route in the direction of travel and in the opposite direction

• All relevant data at the destination

Google online search using voice interactive system (Europe only)

The new function Google online search via voice interactive system enables user-deﬁ ned text searching without taking your hands oﬀ the steering wheel. The function Online destinations currently provided by Google has been a permanent feature of the MMI Navigation plus with web-enabled Bluetooth car phone since the AudiA8'10. It is now also controllable by voice command. For the Online destinations function, Google searches the internet for the places of interest desired by the user.

There are two diﬀ erent input options for selecting an online destination.

1. The user wishes to search for places near the present location,

the destination or another location.

The user enters the voice command "Online destinations" and is given a choice of:

• Google nearby places search for present location

• Google nearby places search for destination

• Google nearby places for diﬀ erent location The user then says the number of the desired option and, when prompted, the desired place of interest (e.g. "ﬂ ower shop"). If the search is to be performed for a diﬀ erent location, then the name of the place must also be stated when prompted by the voice control system.

Online destinations function then searches for relevant places near to the current location with the aid of Google. Afterwards, a choice of possible places is shown (see Figure 603_038 each place is shown. Now the user is prompted by the voice control system to say the number of the desired place of interest. If none of places listed is suitable, more places can be shown by speaking the voice command "Next page".

The selected place of interest can then be adopted as a destination

for the navigation system and route guidance to that location started immediately.

2. The user wishes to search directly for the present location.

Exclusively for an online search for places of interest near the present location, the user can use the short voice command "Online destination" followed by the type of place to be searched for in the same sentence. As an example, let us take a user wanting to buy roses for his wife. He must say the following all at once after pressing the voice input button: "Online destination ﬂ ower shop".

Notes

To use the Online destinations function, there must be a data connection established. AUDI recommends the use of a ﬂ at-

rate data service. AUDI has no inﬂ uence whatsoever over the places of interest shown. They are provided directly by Google.
