The short -term memory collects driving informa­
tion from the time the ignition is switched on un­
til it is switched off . If you cont inue driv ing with­
in two hours after switching the ignition off, the
new values are included when calculat ing the cur­
rent tr ip informat ion.
Unlike the short-term memory, the long-term
memory is not erased automat ically. You can se­
lect the time period for evaluat ing trip informa­
tion yourself .
Fuel con sumpti on
The current fue l consumption can be shown us­
ing a bar graph

tion stored in the short-term memory is also dis­
played. If the bars are green or the gray tone on
the bars changes (depending on the equipment),
your veh icle is sav ing fuel by the following func­
tion:

Automatic transmission
Introduction
Applies to: vehicles with automatic transm issions
The automat ic transmission is controlled elec­
tronically. The transmission shifts up o r down au­
tomatically depend ing on which drive program is
se lected .
When a
moderate drivi ng style is used, the
transmission selects the most economical driving
mode. The transmiss ion upshifts at a lower RPM
and downshifts at a higher RPM to improve fuel
efficiency .
The transm ission switches to a sporty mode after
a kick-down or when the driver uses a
s po rty
d rivi ng style
character ized by quick accelerator
pedal movements, heavy acceleration, frequent
D rivi ng
changes in sp eed and traveling at the maximum
speed.
If des ired, t he d river can also se lect the gea rs
manually (tiptronic mo de) ¢ page 94 .
S tronic transmission
The S tron ic is a dual-clutch transmission . Power
is transferred using two clutches that work inde­
pendent ly from one another. They rep lace the
torque conve rter used in convent io nal automatic
transm issions and allow the vehicle to accelerate
without a noticeable interruption in traction.
tiptronic transmission
In th e tiptronic transmission, power is t ransfer­
red by a torque conve rter.

i ng action oppos ite to that when backing up your
ve hicle w ithout a trailer.
M ain tain a greater d istance between your vehicle
and the one in front of you. Yo u wi ll nee d more
room to stop. To compensate fo r th e tra iler, yo u
will need a larger than no rmal turn ing rad ius.
When pass ing, remembe r th at you ca nnot accel ­
erate as fast as you norma lly wou ld because of
the added load. Make s ure yo u have eno ugh room
to pass. After passing , allow plenty of room fo r
your tra ile r before changing lanes again.
Avoid jerky starts, s harp turns or ra pid lane
changes .

Audi active lane assist
Description
Applies to: ve hicles wit h Aud i act ive lane ass ist
Active lane assist (lane departure warning) de­
tects lane marker lines within the limits of the
system using a camera in the windshield . If you
are approach ing a detected lane marker line and
it appears likely that you will leave the lane, the
system w ill wa rn you w it h corre ct ive steer ing .
You can overr ide th is steering at any time . If yo u
pass over a line, the steer ing whee l wi ll vibrate
lightly. In order for this warning vibration to oc ­
cur, it must first be switched on in the Infotain­
ment system. Active lane assist is ready for oper­
ation when the lane marker line is detected on at least one side of the vehicle.
The system is designed for driving on express ­
ways and highways and therefore only activates at speeds above approximately 40 mph (6S km/
h).
Applies to: vehicles with side assist: if you acti­
vate a turn signal when active lane assist is ready
and it classif ies a lane change as critical because
of vehicles traveling alongside you or approach­ ing you, there w ill be not iceable correct ive steer­
i ng shortly before you leave the lane . This will at­
tempt to keep your veh icle in the la ne.
Applies to: vehicles w ithout s ide ass ist : the ready
system does not warn you if you activate a turn
A ss ista nce sys te m s
signal before crossing the lane marker line. In
t h is case, it assumes that you are changing lanes
intentionally .
Applies to: vehicles wi th adap tive c ruise contro l:
there is no corrective steering or warnings if the
system recognizes a distinct passing maneuver .
If the condit ions are met, traffic jam ass ist
switches on at speeds under approximately
40 mph (65 km/h)
qpage 116.
A WARNING
=
- The system warns the driver that the vehicle
is leaving the lane using corrective steering.
The driver is always responsible fo r keeping
the vehicle within the lane.
- The system can help you keep the vehicle in
the lane, but it does not drive by itself. Al­
ways keep your hands on the stee ring
wheel.
- Cor rective stee ring may not occur in certain
situations, such as during heavy b raking.
- There may be cases whe re the camera does
not recognize all lane marker lines. Cor rec­
tive steering can only take place on the s ide
of the vehicle where lane marker lines are
detected.
- Other road structu res or objects could poss i­
b ly be identified unintentionally as lane
marker lines . As a result, corrective steering
may be unexpected or may not occur.
- The camera view can be restricted, for ex­
ample by vehicles driving ahead or by rain,
snow, heavy spray or light shining into the
camera. Th is can result in active lane ass ist
not detecting the lane marker lines or de­
tect ing them incorrectly .
- In certain s ituations where visibility is low,
the vehicle may switch from an "early" to
"late" steering correct ion.
- Under certain condit ions such as ruts in the
road, an inclined roadway or crosswinds, the
correct ive steer ing alo ne may not be enough
to keep the vehicle in the middle of the lane .
- For safety reasons, act ive lane assist must
not be used when there are poor road and/
or weather conditions such as slippery roads, fog, gravel, heavy rain, snow and the
125

Assistance systems
There is a temporary malfunction that may pre­
vent the active lane assist from switching on. Try
sw itch ing the active lane assist on again later.

Side assist (lane change ass ist) helps you mon itor
your blind spot and traffic behind yo ur vehicle.
Within the limits of the system, i t warns you
about veh icles that are coming closer or that are
traveling with you within sensor range
(D
¢ fig. 12 7. If a lane change is classified as criti­
ca l, the display @in the exterior mirror turns on
¢fig. 128.
The display in the left exterior mirror provides as­
sistance when making a lane change to the left,
while the display in the right exterior mirror pro­
vides assistance when making a lane change to
the right.
Information stage
As long as you do not activate the turn signal,
side assist
informs yo u about vehicles that are

Ass is tan ce sys tems
-If the lanes are narrow or if your are driving on
the edge of your lane. If this is the case, the system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
-If you are driving through a curve . Side assist
may react to a vehicle that is in the same lane
or one lane over from the adjacent lane.
-If side assist reacts to other objects (such as
roadside structures like guard rails).
- In poor weather condit ions . The side assist
funct ions are limited.
Do not cover the radar
sensors ¢ fig. 130 with
stickers, deposits, bicycle wheels or other ob­
jects, because this will impair the function. Do
not use side assist when towing a trailer. For in­
formation on cleaning,
see¢ page 354 .
A WARNING
-Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a dr iver's attention . The driver alone
is a lways responsible for lane changes and
similar d riving maneuvers.
-In some situat ions, the system may not
function or its funct ion may be limited. For
example :
-If vehicles are approach ing or being left
behind very quickly. The display may not
turn on in t ime .
-In poor weather conditions such as heavy
rain, snow or heavy mist.
-On very wide lanes, in tight curves, or if
there is a rise in the road surface. Vehicles in the adjacent lane may not be detected because they are outs ide of the sensor
range .
(D Note
The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. Th is can impa ir the system. Have
an authorized A udi dealer or authorized Audi
Serv ice Facility check their function .

Assistance systems
Description
Applies to: vehicl es w ith Aud i drive select
The follow ing systems, among other things, are
influenced by drive select:
Engine and automatic transmission*
Depending on the mode, the engine and auto­
mat ic transmission* respond more quickly or in a
mo re balanced manner to accelerator pedal
movements . In the sporty
Dynamic mode , the
transmission shifts at highe r speed ranges.
Suspension control*
The suspension control* uses sensors to record
information regard ing steering movements ,
braking and acceleration operations by the driv­
er , road surface, driving speed, and load. This
makes it possible to adapt damping to the driv­
ing situation nearly in rea l time. With drive se ­
lect, you can adjust the suspension control to
sporty
( Dynamic ), comfortab le ( Comfort ) or bal­
anced
( Auto ).
Steering
The power steering adapts. Indi rect s teer ing that
moves easily as in
Comfort mode is especia lly
suited to long drives on highways . The
Dynamic
mode provides sporty , direct steering.
The following applies to vehicles with dynamic
steering* : the steering ratio changes based on
vehicle speed in order to maintain optimum
steer ing effort for the driver at all times . This
sets the steering to be less sensitive at higher
speeds in order to prov ide improved vehicle con­
trol. At reduced speeds, steering is more direct in
order to keep the steering effort as min imal as
possible when the driver is maneuvering the vehi­
cle. At low and average speeds, dynamic steer­
ing* additionally provides more responsive steer­
ing performance.
Sport differential*
As a component of the all wheel drive system
(quattro)
~ page 1 SO, the sport differential dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the selected mode
134
from moderate (Comfort ) to sporty (Dynamic ).
The goal is a high level of agility and ability to ac­
ce lerate on curves . The vehicle is very respons ive
to steering.
Adaptive cruise control (ACC)*
The behavior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner.
Engine sound*
The engine sound adapts to the current mode
and can be subtle to sporty.
@ Tips
The S selector lever position automatically en­
gages when the
Dynamic mode is selected .
Selecting the driving mode
Applies to: vehicles with Audi drive se lect
Fig. 135 Center co nsole: controls for drive se lect
