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 light steering.
Descript ion
The vehicle setup in each mode depends on
the vehicle's features. The engine, transmis­
sion, steering, reversible safety belt tension ­
ers and adaptive air suspension are always in­
volved .
Engine and transmission
Depending on the mode, the engine and the
transmission respond more quickly or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the
transmission sh ifts at higher RPMs.
Air suspension
The adaptive air suspension/adaptive air sus­
pension sport*
( Air suspension in the MMI) is
an electronically cont rolled air suspension and
damping system. They are adjusted depend­ ing on the selected driving mode, the driver's
steering, braking and acceleration input and
the road s urface, veh icle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport *.
The vehicle clearance va ries depending on the
selected mode and the speed .
The highway setting is activated automatically
when you drive above 75 mph (120 km/h) for
mo re than 30 seconds in the
auto or dynamic
mode. The g round clearance is increased auto-
Audi drive select 103
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 steering that
moves easily as in comfort mode is especially
s ui ted to long drives on a highway. In con­
trast, dynamic mode provides sporty, direct
steering.
T he following applies to vehicles with dynamic
steering*: the steering ratio changes based on
vehicle speed in order to maintain 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.
Sport diffe rential*
As a component of the all whee l drive system
(quattro
® ) c> page 191, the Sport differen­
tial* distributes the driving power to the rear
axle depending on the situat ion. The dis tribu­
tion of power varies depending on the select­
ed mode, from balanced (comfort) to agile
(dynamic). The goal is a hig h level of agility
and ability to accelerate on curves. Th e vehi cle
is very responsive to steer ing.
Adaptive cruise control*
The behav ior when accelerating can be adjust
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control al­
so responds to the driving behavior of the ve­
hicle ahead in a more conserva tive or sporty
manner.
(D 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 condi­
tions and changes to the driving modes,
w hich can affect clearance.
- When transporting the vehicle on a car
carrier, train, ship or by other means, on-
ly tie the vehicle down at the running

Audi pre sense Preventative passenger
protection
App lies to veh icles: with Audi p re se nse
Audi pre sense can initiate steps to help pro­
tect vehicle occupants in certain situations.
The funct ions descr ibed depend on equipment
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 Audi drive select*: the deploy­
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:
- Audi braking guard
c> page 93
-Tightening the safety belts
- 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 col lision with the vehicle
coming from behind is also calculated. If the
Audi pre sense 185
risk of a collision is detected, the following
functions can be triggered:
- Tightening 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 of 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
veh icle's path
c> page 87.
- 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.

188 Intelligent technology
ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-s lip regulat ion (ASR), e lectronic
d ifferential lock ( EDL), dynamic steering* and
e lectronic interaxle differentia l lock*. ESC is
switched on all the time. I n certa in s ituations
when you need less tract io n, you ca n sw itch
off ASR by pressi ng the button above
~ page 189, fig. 167 the se lector lever. Be
sure to sw itch ASR on ag ain when you no lon­
ger need less trac tion.
Anti -lock braking system (ABS)
ABS prevents t he wheels from locking up
when braking. The veh icle can still be st eered
even d uring ha rd b rak ing . Apply steady p res­
sure to the br ake ped al. Do no t pu mp the ped­
a l. A puls ing in t he bra ke peda l ind icates that
the system is he lping yo u to b rake the vehicle .
Brake assist system
The brake assist system can decrease b ra kin g
d ista nce. It increases braking powe r w hen the
d river p resses the brake pedal quickl y in eme r­
gency situa tions . You mus t press and ho ld the
b rake peda l until the situation is over. In vehi­
cles with adaptive cruise control*, the brake
assist system is more sensitive i f the d istance
detected to the vehicle ahead is t oo smal l.
Anti-slip regulation (ASR)
ASR reduces engine power w hen the drive
wheels begin to spin and adapts the fo rce to
the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic differential lock (EDL )
The E DL brakes wheels that are spinn ing and
transfers the drive powe r to the o ther d rive
wheel o r whee ls if the vehic le is equipped with
a ll whee l drive*. This funct ion is available up
to about 7S mph (120 km/h).
I n extreme cases , EDL automatica lly swit ches
off to help keep the brake on the braked whee l
from overheating. ED L wi ll switch on again au­
tomatically when conditions have returned to normal.
Dynamic steering*
On vehicles wi th dynam ic s teeri ng, ES C helps
stab ilize the steer ing in cer tain sit uations.
Electronic interaxle differential lock
function*
T he ele ctronic i nte raxle di fferentia l lock f unc ­
tion ac tiva tes when dr iving t hrough curves.
B ra king is targeted towar d the whee ls on the
inside of the curve as needed . This helps to
min imi ze front whee l skid, improves traction
and allows for more precise driving throug h
cu rves .
A WARNING
- ESC, ABS, ASR , EDL, dynamic steering*
and the elect ronic interaxle differential
loc k function* cannot ove rcome t he laws
of physics . This is espe cially im po rtant
on slippery o r we t road s.
If the sys tems
begin actin g to stabilize your veh icle, you
should immediately change yo ur speed
to match the road and t raffic 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 cont ro l, collision and ser io us per­
sonal injur ies .
-Always ada pt your speed to road , traffic
and wea ther conditions. The risk of los­
ing contr ol of the vehicle i ncreases wh en
d riving too fast, espe cially through
curve s and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead. ESC, ABS, the brake ass ist sys ­
tem, EDL, ASR, dynam ic steering * and
the elect ron ic interaxle differential lock
function * cannot prevent co llisions.
- Always accelerate with s pecial care on
even, smooth s urfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance sys tems that cannot al­
ways he lp to red uce the risk of loss of ve ­
h icle co nt ro l.

@ Tips
-ABS and ASR on ly work correctly when
all four wheels are equ ipped with identi­
cal t ires. Different tire s iz es can lead to a
reduct ion in eng ine power.
- You may hear noises when the systems
described are working.
- If the indicator light

Braking
General information
What affects braking efficiency?
Operating cond itions and driving h abits
The brakes o n today's automobiles are still
subject to wear, depend ing largely on operat­
i ng condit ions and driving habits ¢&, . On ve­
hicles that a re either dr iven most ly in stop­
and-go c ity t raff ic or are dr iven hard, the
brake pad s should be checked by yo ur author ­
i zed Audi dealer more often than specified in
the
Warranty & Maintenance booklet. Failure
to have your brake pads inspected can result in reduced brake performance.
On steep slopes, you sho uld use the braking
effect of the eng ine . T his way, you prevent un­
necessary wear on the brake system . If you
must use your brakes, do not hold the br akes
down cont inuous ly . Pump the brakes a t in ter­
vals .
Moisture o r ro ad sa lt
Under certa in conditions, for example, when
driv ing through water or very heavy ra in, or
even after washing your veh icle, the braking
effec t can be reduced due to moisture (or in
freez ing cond itions ice) on the brake pads . A
few carefu l brake applications should dry off
the b ra ke pads or remove a ny ice coatings.
When you are driving a t higher speeds with
the windsh ie ld w ipers on , the brake pads will
