Audi drive select Driving settings
Introduction
Aud i drive select makes it possible to experi­
ence different types of vehicle settings in one
veh icle. The driver can select th ree
Comfort,
Auto
and Dynamic modes in the MMI to
switch between a sporty and a comfortable
driving mode.
You can also adjust the setting according to
your preferences in the
individual mode. For
examp le, you can combine settings such as a
sporty engine tuning with comfortab le steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and seri­
ous personal injury .
Description
The vehicle setup in each mode depends on
the vehicle's features. The engine, transm is­
sion, steering, reve rsible safety belt tension­
ers and adaptive air suspension are always in­
volved.
Engine and transmission
Depending on the mode, the engine and the
tra nsmission respond quicker or in a more bal­
anced manne r to acce lerator pedal move­
ments. In the sporty dynamic mode, the
transmission shifts at higher RPMs .
Air suspension
The adaptive air suspension/adaptive air sus­
pension sport*
( Air suspension in the MMI) is
an electronically con trolled air suspension and
damping sys tem. They are adjusted depend­
ing on the selected driving mode, the drive r's
steering, braking and acceleration input and
the road s urface, vehicle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport*.
Audi drive select 109
The vehicle clearance varies depending on the
selected mode and the speed .
T he hig hway setting is activated automatically
when you drive above 75 mph (120 km/h) for
more than 30 seconds in the
auto or dynamic
mode. The ground clearance 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 ratios . Indirect stee ring that
moves easily, like the steering in comfort
mode, is best suited to long drives on a high­
way . In contrast, dynamic mode provides
sporty, direct steer ing .
The following applies to vehicles with dynamic steering* : the steering ratio changes based on
vehicle speed in order to ma inta in optimum
steering effort for the driver at all times. This
sets the steering to be less sens itive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steer ing
is mo re direct in order to keep the steering ef­
fort as minimal as possible when the driver is
maneuvering the vehicle. At low and average
speeds, dynamic steering additiona lly pro­
vides more responsive steering performance.
Sport differential*
As a component of the all whee l dr ive system
(quattro ®)
<:!) page 203, the Sport differen­
tia l* distributes the driving power to the rear
axle depending on the situation . The distribu ­
tion of power varies depending on the select ­
ed mode, from balanced (comfort) to agile
(dynamic). The goal is a high level of agility
and ability to accelerate on curves . The vehicle
is very responsive to steering.
Curve light*
The curve light adapts to driving on curves.
The pivoting act ion and the lighting are also
adapted to the mode.
Adaptive cruise control*
The behavior when accelerating can be adjust­
ed from comfortab le to sporty, depending on .,..

110 Audi drive select
the drive se lect mode. Adaptive cruise control
a lso responds to the driving behavior of the
vehicle ahead in a more conservative or sporty
manner.
Engine sound*
The sound of the engine is adapted to the se­
lected mode and ranges from subtle to sporty .
Q) Note
-Make sure there is enough clearance
above and below the vehicle when park­
ing. The height of the vehicle can change
once it is parked due to temperature
fluctuations, changes to the load cond i­
tions and changes to the dr iv ing modes,
which can affect clearance .
- When transporting the vehicle on a car
carr ier, tra in, ship or by other means, on­
l y tie the veh icle down at the running
surface of the tires, which is the outer
ci rcumfe rence . Securing the vehicle at
the axle components, s uspension str uts
or towing eyes is not pe rmitted because
the press ure in the air suspension s truts
can change during transport. The vehicle
may not be sec ured s ufficient ly if this
happens.
- If you are going to tow a trailer, you must activate the trailer ope ration mode
c:> page211.
(D Tips
-In some mode ls, the maxim um vehicle
speed can on ly be reached in the
auto
and dynamic modes.
- Se lecting the
dynamic mode results in
sporty shifting characteristics. The S
gear position engages automatically.
- In vehicles that have dynamic steering*,
operating noise is heard when starting or
stopping the eng ine. This does not ind i­
cate a problem. -
In vehicles w ith sport different ia l* , the
dynamic mode is deactivated when tow­
ing a tra iler.
Selecting the driving mode
You can choose between Comfort, Auto , Dy­
namic and Individual.

118 Autom atic Tran smissi on
preve nt the vehicle from "creep ing" , you
must keep your foot on the brake in all
selector lev er positions except P and N
when the e ng ine is r unning. Do not inad­
vertently press the accelerator pe dal
w hen the veh icl e is stationary . Otherwise
the vehicle will s tart to move immediate­
ly, even if the park ing brake is se t. This
cou ld result in a c rash.
- Do not ride the brakes or press the brake
peda l too often or too long when dr iving
down a hill. Constant braking causes the
brakes to ove rheat and s ubstant ially re­
duces braking performance, increases
braking distance or causes comp lete fail­
ure of the brake system.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
H ill descent control is activated when these­
lector lever is in D/S and you press t he b rake
pedal. The transmission automat ically se lects
a gear that is suitab le for the incline. Hill de­
scent control tries to maintain the speed ach­ ieved at the time of brak ing, within physical
and techn ical limitations. If may still be nec­
essary to adjust the speed with the brakes .
H ill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
Hill descent control is also activated when the
speed is set by starting the cruise control sys­
tem c:>
page 90.
A WARNING -
Hill descent control ca nnot overcome
physical limitations, so it may not be able
t o maintain a constant speed under all
condi tion s. Alw ays be ready to ap pl y the
bra kes.
Shifting manually
The shift paddles allow the driver to shift the
gears manually .

Audi pre sense
Preventative passenger
protection
A pp lies to veh icles: with Audi pre se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The functions described depend on equ ipment
installed in your vehicle:
Audi pre sense basic
The following functions can be triggered in
certain driving situations:
- Tightening of the safety belts (for example,
during heavy braking) : the front safety belts
have reversible belt pretensioners. If a colli­
sion does not occur, the safety belts loosen
slightly and are ready to be tightened again.
- Closing the windows and the sunroof*: the
windows and the sunroof* close leaving a
small open gap.
Audi pre sense basic functions can be trig­
gered at speeds above 20 mph (30 km/h).
Vehicles with Aud i drive select*: the dep loy­
ment time is adapted in dynamic mode.
Audi pre sense front (vehicles with
adaptive cruise control*)
Audi pre sense front includes the functions in
Audi pre sense basic. In addition, within the
limits of the system, the likelihood of a colli ­
sion with the vehicle immediately ahead is al­
so calculated . If the system senses an immi­
nent collision the following functions can be
tr iggered :
- Braking guard
c::> page 99
- Tightening the safety be lts
- Closing the windows and the sunroof* (leav -
ing a small open gap)
Audi pre sense rear (vehicles with Audi
side assist*)
Audi pre sense rear includes the functions in
Audi pre sense basic. In addition, the likeli­
hood of a rear-end collision with the vehicle
coming from behind is also calcu lated.
If the risk
of a co llision is detected, the following
functions can be triggered:
- Tig htening the safety belts
- Closing the windows and the sunroof* (leav-
ing a small open gap)
- Adjusting the seats: the settings for the
power head restrains, the upper sections of
the backrests and the pneumatic side bol­
sters* are optim ized for the front seats and
the outboard rear seats*. If a collision does
not occur, the previous seat settings are re­
stored.
Audi pre sense plus
Audi pre sense plus includes the funct ions in
Audi pre sense front and Audi pre sense rear.
Error message
Audi pre sense: not available
Preventative passenger protection is not avail­
able. See your authorized Audi dealer immedi­
ately to have the malfunction corrected .
A WARNING
-Audi pre sense cannot overcome the laws
of physics.
It cannot prevent a collision. Do
not let the increased safety provided
tempt you to take risks. This will increase
the risk o f a collision and serious personal
injuries.
- The sensors cannot always detect all ob­
jects . This increases the risk of a colli ­
sion.
- Audi pre sense does not detect people or
animals or objects that are crossing the
vehicle's path
c::> page 93.
-The radar sensor's vision can be reduced
by heavy rain, ice, snow, heavy road spray
and reflections from guard rails, tunnel
entrances, etc. These and similar condi­
tions can prevent vehicles from be ing ac­
curately detected and in some cases they
may not be detected at all.
Ill>

ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-s lip regulat ion (ASR), electronic
d ifferential lock (EDL), dynamic steering* and
electronic interaxle differential lock*. ESC is
sw itched on all the time . In certain s ituations
when you need less tract ion, you can sw itch
off ASR by pressing the button above
~ page 200, fig. 188 the se lector lever. Be
sure to sw itch ASR o n aga in when yo u no lon­
ger need less traction.
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The veh icle can still be steered
even du ring ha rd b raking . Apply steady p res­
sure to the brake pedal. Do not p ump the ped­
a l. A pulsing in the brake peda l indicates that
the system is he lping you to brake the vehicle .
Brake as sist system
The brake assist system can decrease bra king
d istance.
It increases braking power when the
driver presses the brake pedal qu ick ly in eme r­
gency situations . You must p ress and ho ld the
brake peda l until the situation is over. In
vehicles with adaptive cruise control*, the
brake assist system is more sensit ive if the
d istance detected to the vehicle ahead is too
small.
Anti- slip regulati on (A SR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic diff erential lo ck (EDL )
The ED L brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all whee l drive*. This funct ion is available up
to about 75 mph (120 km/h).
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
Int ellig ent technolog y 199
Dynamic ste ering *
On vehicles with dynam ic steering, ESC helps
stabilize the steering in certain situations.
Electronic intera xle differential l ock
function*
T he electron ic i nteraxle differential lock f unc ­
tion activa tes when dr iving th ro ugh curves.
Braking is targeted toward the wheels on the
inside of the curve as needed. This he lps to
minimize front whee l skid, improves traction
and allows for more precise driving through curves .
A WARNING
- ESC, ABS, ASR, EDL, dynamic steering*
and the elect ronic interaxle differential
loc k function* cannot ove rcome the laws
of physics. This is espec ially important
on slippery or we t roads.
If the systems
begin acting to stabilize your veh icle, you
should immediately change yo ur speed
to match the road and traffic conditions .
Do not let the increased safety provided
by these systems tempt you to take risks.
Doing so will increase the risk of a loss of
veh icle contro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic and weather conditions. The risk of los­ing con trol of the vehicle increases when
driving too fast, espe cially through
curves a nd on slippe ry or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL, ASR, dynam ic steering* and
the electron ic interaxle d ifferential lock
function" cannot prevent co llisions.
- Always accelerate with spec ial care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
hicle control.

This also applies to cleaning headlights
and painted bumpers. Remember: the
closer the nozzle is to the surface of the
material, the greater the stress on the ma­
terial.
Caring for vehicles with matte finish
paint
Ap plies to vehicles: with matte fi nish pa in t
Vehicles with matte finish paint require spe­
cial care due to the characteristics of the
paint.
Washing by hand
To avoid damaging the paint when washing,
first remove dust and large particles from
your vehicle. Insects, grease spots and finger ­
prints are best removed with a
special cleaner
for matte finish paint.
Apply the product using a microfiber cloth . To
avoid damaging the paint surface, do not use
too much pressure .
Rinse the vehicle thoroughly with water . Clean
the vehicle starting at the top and working to­
ward the bottom using a
neutral shampoo
and a soft microfiber cloth . Stop frequently to
rinse the cloth thoroughly .
Clean the wheels and sill panels last. Use a
clean
sponge on these areas.
Rinse the vehicle thoroughly again and let it
air dry. If there are any water spots, they can
be removed using a
leather cloth.
Clean again with the special cleaner for matte
finish paint
if necessary.
Removing stubborn dirt
Bird droppings or tree sap
are best removed
with plenty of water and a microfiber cloth.
You should rinse off
gasoline residue immedi­
ately with plenty of water.
_& WARNING
- Wash your vehicle only when the ignition
is switched off to reduce the risk of a
crash. -
Always read and heed all WARNINGS and
other information ¢
