Audi drive select
Driving settings
Introduction
Aud i drive select makes it possib le to experience
d ifferent types of veh icle sett ings in one veh icle.
The driver ca n select three
Comf ort, Aut o and
Dyn am ic modes in the MMI to switch between a
sporty and a comfortable driving mode.
You can a lso adjust the setting accord ing to your
p references in the
indi vidual mode. For example,
you can combine settings such as a sporty engine tuning with comfortable steering.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and t ransm is sion
Depending on the mode, the engine and the
transmission respond quicker or in a more ba l­
anced manner to accelerator pedal movements.
In the sporty dynamic mode, the transmission
shifts at h igher RPMs.
Air suspe nsion
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
electronically controlled air suspens ion and
damping system . They are adjusted depending
on the se lected dr iving mode, the driver's steer­
ing, b raking and acceleration input and the road
surface, vehicle speed and load. A spo rty setting
is gene rally used in veh icles with adaptive air sus­
pens ion sport*.
The vehicle clearance va ries depending on these­
lected mode and the speed .
The highway setting is activated automatically
when yo u drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
au to or dynamic
106
mode. The ground clea rance is increased auto ­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
The steering adapts in terms of steering effort
and steering rat ios. Indirect stee ring that moves
easily, like the steering in com fort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering .
The following app lies to veh icles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain optimum
steering effort for the dr iver at a ll times . This
sets the steering to be less sensitive at higher
speeds in order to provide improved vehicle con­
trol. At reduced speeds, however, steering is more d irect in order to keep t he steering effort as
min imal as possible whe n the dr iver is maneuve r­
i ng the vehicle. A t low and ave rage speeds, dy­
namic steeri ng addit ionally prov ides more re ­
spons ive steering performance.
Sport differential*
As a component of the all whee l dr ive sys tem
(quattro)
~ page 195, the Sport differe ntia l*
dist ributes t he d riving powe r to the rear axle de ­
pend ing on the s ituation. The distr ib ution of
power va ries depending on the selected mode,
from ba lanced (comfort) to agile (dynamic). The
goal is a high level of agility and ability to accel­
erate on curves. The vehicle is very responsive to
steering.
Cur ve light *
The curve light adapts to driving on curves . The
pivoting action and the lighting are also adapted
to the mode.
Adapt ive cruise control*
The behavio r whe n accelerating ca n be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise contro l also
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner . ..,_

Engine sound *
The sou nd of the engine is adapted to the select­
ed mode and ranges from subt le to sporty.
(D Note
- Make sure there is enough cle arance above
and below t he vehicle when parking. The
height of the vehicle can change once it is
parked due to temperature f luctuations,
changes to the load conditions and changes
to the driving modes, which can affect clear­
ance.
- When transporting the vehicle on a car car­
rier, tra in, ship or by other means, only t ie
the vehicle down at the running surface of
the tires, which is the outer circumference.
Securing the vehicle at the axle compo­
nents, suspe ns ion struts or towing eyes is
not permitted be cause the press ure in the
air suspension struts can change dur ing
transport . The vehicle may not be secured
sufficiently if this happens .
-If yo u are going to tow a tra ile r, you m ust
activate the trailer operation mode
<:!;>page 202.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
auto and
dynamic modes.
- Se lecting the
d ynami c mode resu lts i n spor­
ty shifting characteristics. The S gear posi­
tion engages a utomatically.
- In vehicles that have dynamic steering*, op ­
erating noise is heard when starting or stop­ ping the engine. This does not indicate a
problem.
Audi driv e se lect
- In vehicles w ith sport differential*, the dy­
namic mode is deactivated when towing a
trailer .
Selecting the driving mode
You con choose between Comfort, Auto , Dynamic
and Individual .

You can change the driv ing mode when the vehi­
cle is stationary or while driving . If traff ic per­
mits, afte r changing modes, briefly take your
foot off the accelerator pedal so that the recently
selected mode is also activated for the engine.
comfort -provides a comfort-oriented vehicle
setup and is suited for long drives on h ighways.
auto -provides an overall comfortable yet dy­
nam ic dr iving feel and is suited for every day use.
dynamic -gives the driver a sporty driving fee l
and is suited to a sporty driving style.

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of skid­
ding and loss of vehicle control. It works only
when the engine is running. ESC detects certain
difficult dr iving situations, including when the
veh icle is beginn ing to spin (yaw) out of contro l
and helps you to get the vehicle back under con­
trol by se lectively braking the wheels, and/or re­
ducing engine power and providing steering as­
sistance to help hold the vehicle on the driver's
intended course. The indicator light
GI in the in­
strument cluster blinks when ESC is taking action
to help you control the vehicle.
ESC has limitations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not always be able to help out under all con­
ditions you may come up against . For example,
ESC may not always be able to help you master
situations where there is a sudden change in the
coefficient of friction of the road surface. When
there is a section of dry road that is suddenly cov­
ered with water, slush o r snow , ESC cannot per­
form the same way it wou ld on the dry surface. If
the vehicle hydrop lanes (rides on a cushion of wa­
ter instead of the road surface), ESC wi ll not be
able to he lp you steer the vehicle because contact
with the pavement has been interrupted and the
vehicle cannot be braked or steered. During fast cornering, part icularly on w inding roads, ESC
cannot always deal as effective ly w ith difficult
driving situat ions than at lower speeds . When
towing a trailer, ESC is not able to help you re­
ga in control as it would if you were not towing a
trai ler.
Always adjust your speed and driving sty le to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limits, increase the
190
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention.
Instead, ESC improves the possib ility of keeping
the vehicle under control and on the road during extreme maneuvers by using the driver's steering
inputs to help keep the vehicle going in the in­
tended direction . If you are traveling at a speed
that causes you to run off the road before ESC
can provide any assistance, you may not exper i­
ence the benefits of ESC.
ESC is switched on all the time. In certa in s itua­
tions when you need less traction, you can sw itch
off ASR by press ing the button above
~ page 192, fig. 186 the selector lever. Be sure
to switch ASR on again when you no longer need
l ess traction.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up when
braking. The vehicle can still be steered even dur ­
i ng hard braking . Apply steady pressure to the
brake pedal. Do not pump the pedal. A pulsing in
the brake pedal indicates that the system is help ­
i ng you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the dr iver
presses the brake pedal quickly in emergency sit­
uations. You must press and hold the brake pedal
u nt il the situation is over. In vehicles with adap ­
tive cruise control*, the brake assist system is
more sensitive if the d ista nee detected to the ve­
hicle ahead is too sma ll.
Anti-slip regulation (ASR)
ASR reduces engine powe r when the dr ive wheels
begin to spin and adapts the force to the road
cond itions. This makes it easier to start, acceler­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels.
This function is not available at higher speeds .
