Audi pre sense basic / pre sense city.
Start-stop system.

Displays and operation
Audi drive select can be configured using Control Unit 1 for
Driving And Convenience Functions E791 or Multimedia
System Control Head E380.

Depending on the vehicle equipment specification, the
drive mode can also be selected on the multifunction steering wheel. When using the multi-function steering wheel,
the options menu is displayed on the MMI screen or in the
instrument cluster.

Audi drive select function
The following systems are influenced by Audi drive select:

System

Vehicle characteristic

Engine and automatic transmission

Depending on mode, the engine and automatic transmission react to accelerator inputs in a more spontaneous or more balanced way. In the sporty dynamic mode, the gear shift points are adjusted to higher in the
RPM band.

Steering

The steering can be adapted with the regard to steering assistance. A distinction is made here between
three characteristics ranging from comfortable (comfort) and balanced (auto) to sporty (dynamic).

Dynamic steering
(not available at
vehicle introduction)

The following applies to models with dynamic steering:
To minimize steering effort for the driver, the steering ratio is adjusted to the speed at which the vehicle is
traveling. At higher speeds, the steering is configured for less sensitivity in order to improve handling. At
lower speeds, the steering is more direct in order to minimize steering effort for the driver during maneuvering, for example. In addition, the dynamic steering system provides a more agile steering response at low
and medium speeds.

Damper control

Audi drive select allows the damper control system to be configured for sporty (dynamic), comfort-oriented
(comfort) or balanced (auto) response.

Adaptive cruise
control (ACC)

Depending on drive select mode, the acceleration response options range from comfortable (comfort) to
sporty (dynamic). Accordingly, the adaptive cruise control also reacts to the driving style of the driver in front
in a more balanced or more spontaneous way.

Sport differential
(not available at
vehicle introduction)

In comfort mode, activation of the sport differential is kept at a minimum. Primarily, load-change reactions
are effectively damped so that the car has a very balanced response.
In auto mode, the sport differential is configured for optimal handling dynamics. The car steers very responsively through corners.
In dynamic mode, the sport differential is at its most noticeable. The dynamic handling has distinctly sporty
feel.

Functional features
• The vehicle remembers the last selected mode and the
individual mode configuration when it is re-started.

• On some models, maximum speed is only achieved in
auto and dynamic modes.

• To activate a newly selected mode for the engine, too,
the accelerator must be briefly released (idle position) or
briefly pushed down into the full throttle position.

• The following applies to models with an automatic
transmission: In dynamic mode, position S is automatically selected.

• To activate the newly selected mode for the steering, the
steering wheel must also be moved into the straightahead position (zero position).

Anti-theft alarm
The anti-theft alarm of the Audi A4 is similar to the
systems used in current Audi models.

The alarm system will be triggered (if active) when a Scan
Tool is connected to the Data Link Connector.

Interior Monitoring Sensor G273 and Vehicle Inclination
Sensor G384 are integrated with Anti-Theft Alarm System
Sensor G578. G578 communicates with Comfort System
Central Control Module J393 over LIN 2.

Central locking
The vehicle can be centrally locked and unlocked in various
ways:
• Using the radio remote key.
• Via the sensors in the door handles (Advanced key).
• Manually via the locking cylinder in the driver's door.
• Using the inner central locking switch (door trim).

The door handle sensors are used for locking and unlocking
with the Advanced key. The door handle sensors are no
longer deactivated after 72 hours. This is not necessary due
to the very low static current.

Programming
There are two processes for programming the HomeLink
System depending on the type of garage door opener used
in the home. A home system may use:
• a fixed code system.
• a rolling code system.

The two code systems are handled differently. A programmed fixed code system is ready for use directly after
programming. In the case of a rolling code system, on the
other hand, the garage door and the in-car HomeLink
system must be synchronized.

Both programing processes are MMI-controlled. The individual steps are displayed on the MMI screen.

The last three programming cycles of the system can be
viewed through the Measuring values. The following information can be seen:
•

Note
It is recommended that two persons perform the adaption process, to synchronize the garage door drive with the HomeLink
system, because there is usually only a very small window available for synchronization.

Note
Individual buttons can be reprogrammed using the menu navigation. This overwrites the previously stored value. All programmed channels can be deleted with menu assistance. Programming can be aborted at any time using the BACK button.

Head-up display
Warnings, selected information from assistance systems
and navigation instructions can be projected onto the
windshield via Windshield Projection Head Up Display
Control Module J898.

J898 communicates over the Infotainment CAN. It can be
accessed with the Scan Tool using Address Word 82.

The head-up display is attached to a cross-member behind
the instrument cluster on an adjustable bracket.
This information is displayed within the driver's field of
vision. The virtual image is only visible to the driver within a
limited area of the windshield. The driver is able to see a
virtual image at a distance of approximately 7 ft (2.1 m)
(image viewing distance).
