Audi drive select Driving settings
Introduction
Drive select makes it possible to experience dif­
ferent types of vehicle settings in one vehicle.
The driver can select
Comfort, Auto and Dynamic
modes in the Infotainment system to switch be­
tween a sporty and a comfortable driving mode.
In the
Individual mode, the settings can be ad­
justed to your personal preferences. This makes it possible to combine settings such as a sporty en­
g ine tun ing with light steering.
_&. WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and serious
personal injury.
Description
-
The follow ing systems are affected by drive se­
lect:
Engine and transmission
Depending on the mode, the eng ine and the
transmission respond quicker or in a more bal­
anced manner to acce lerator pedal movements.
I n the sporty dynamic mode, the transmission
shifts at higher RPMs.
Air suspension*
The adaptive air suspension/adaptive air suspen­
sion sport*
(Air suspension in the MMI) is an
e lectronically controlled a ir suspension and
damping system. They are adjusted depending on
the selected driving mode, the driver's steering,
b raking and acce leration input and the road sur­
face, vehicle speed and load. A sporty setting is generally used in vehicles with adaptive air sus­
pension sport*.
The vehicle clearance varies depending on these­ lected mode and the speed.
The highway setting is activated automatically
when you drive above 75 mph (120 km/h) for
more than 30 seconds in the
Auto or Dynamic
Audi drive select
mode. The ground clearance is increased auto­
matically if the speed drops below 44 mph (70
km/h) for more than 120 seconds.
Steering
T he steering adapts in terms of steer ing effort
and steering ratios . Indirect steering that moves
easily, like the steering in comfort mode, is best
suited to long drives on a highway. In contrast,
dynamic mode provides sporty, direct steering.
T he following applies to vehicles with dynamic
steering*: the steering ratio changes based on ve­
hicle 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 provide improved vehicle control. At re­
duced speeds, however, steering is more direct in
order to keep the steering effort as minimal as
poss ible when the driver is maneuvering the vehi­
cle. At low and average speeds, dynamic steer ing
additionally provides more responsive steering
performance.
Sport differential*
As a component of the all wheel dr ive system
(quattro)
¢ page 192, the Sport differential* dis­
tributes the driving power to the rear axle de­
pending on the sit uation. The distribution of
power varies depending on the selected mode,
from balanced (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.
Curve light*
T he curve light adapts to driving on curves. The
pivoting action and the lighting are also adapted
to the mode.
Adaptive cruise control*
T he behav ior when accelerating can be adjusted
from comfortable to sporty, depending on the
drive select mode. Adaptive cruise control a lso
responds to the driving behavior of the vehicle
ahead in a more conservative or sporty manner. ..,_

-An Advanced Airbag with gas generator and
control valve for the driver inside the steering
wheel hub.
- An Advanced Airbag with gas generator and
control valve inside the instrument panel for
the front passenger .
- A capacitive passenger detection system under­
neath the front passenger seat cover. This sys­
tem measures the electrical capacitance of the
person in the seat. The information registered
is sent continuously to the electronic control
unit to regulate deployment of the front Ad­
vanced Airbag on the passenger side .
- An airbag monitoring system and indicator
light in the instrument cluster~
page 154.
-A sensor in each front seat registers the dis­
tance between the respective seat and the steering wheel or instrument panel. The infor­
mation registered is sent continuously to the
electronic control unit to regulate deployment
of the front Advanced Airbags.
- The
PASSENGER AIR BAG OFF light comes on
and stays on in the center of the instrument
panel ~
page 155, fig. 160 and tells you when
the front Advanced Airbag on the passenger side has been turned
off.
- A sensor in the safety belt latch for the driver
and for the front seat passenger that senses
whether that safety belt is latched or not and
transmits this information to the electronic control unit.
A WARNING
Damage to the front passenger seat can pre­
vent the front airbag from working properly.
- Improper repair or disassembly of the front
passenger and driver seat will prevent the
Advanced Airbag System from functioning properly.
- Repairs to the front passenger seat must be
performed by qualified and properly trained
workshop personnel.
- Never remove the front passenger or driver
seat from the vehicle.
~ - Never remove the upholstery from the front <(
~ passenger seat.
~ -Never disassemble or remove parts from the 1.1'1
N seat or disconnect wires from it. ID ......
Airbag system
-Never carry sharp objects in your pockets or
put them on the seat. The capacitive pas­
senger detection mat in the front passenger
seat will not function properly if it is punc­
tured.
- Never carry things on your lap or carry ob­
jects on the front passenger seat . Such ob­
jects can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- Never store items under the front passenger
seat. Parts of the Advanced Airbag System
under the passenger seat could be dam­
aged, preventing them and the airbag sys­
tem from working properly.
- Never place seat covers or replacement up­
holstery that have not been specifically ap­
proved by Audi on the front seats.
- Seat covers can prevent the Advanced Air­
bag System from recognizing child re­
straints or occupants on the front passenger
seat and prevent the side airbag in the seat
backrest from deploying properly.
- If a seat heater has been retrofitted or oth­
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
- Never use cushions, pillows, blankets, or
similar items on the front passenger seat .
The additional layers prevent the capacitive
passenger detection system from accurately
measuring the capacitance of the child safe­
ty seat and/or the person on the seat and
thus keep the Advanced Airbag System from
working properly.
- Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat if the device is connected to the 12-volt
socket or the cigarette lighter socket. Such
devices can influence the capacitance regis­
tered by the capacitive passenger detection
system, so that incorrect information is pro­
vided to the airbag control unit.
- If you must use a child restraint on the front
passenger seat and the child restraint

Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of sk id­
d ing and loss of veh icle control.
It works only
when the engine is runn ing. ESC detects certa in
d ifficult d riving situations, including when the ve­
h icle is beginn ing to sp in (yaw) o ut of control and
he lps you to ge t the veh icle back u nder cont ro l b y
selec tively braking the whee ls, and/or reduc ing
engine power and providing steering assistance
to help hold the vehicle on the driver's i ntended
course. The indicator light
DJ in the instrument
cluster blinks when ESC is taking action to help
you control t he veh icle.
ESC has lim itations. It is important to remember
that ESC cannot overcome the laws of physics. It
will not a lways be ab le to he lp out under all con­
d itions 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. Whe n
there is a section of d ry road tha t is s udden ly cov ­
ere d wi th wa ter, s lush or snow, ESC ca nnot per­
form the same way it wou ld on the d ry s urface . If
the vehicle hydroplanes ( rides on a cushion of wa ­
ter instead of t he road surface), ESC wi ll not be
ab le to he lp you steer the veh icle because contact
with the pavement has been i nterrupted and the
ve hicle cannot be b raked or steered. Dur ing fast
cor ne ring, particula rly o n w inding roads, ESC
cannot a lways deal as eff ect ively wi th d iff icu lt
d riving situat ions than at lowe r speeds.
Always ad just your speed and dr iv ing style to
road, traffic and weather conditions. ESC ca nnot
over ride the vehicle's physical limi ts, increase t he
ava ilab le tract io n, or keep a vehi cle on t he road if
roa d de pa rture is a res ult o f driver in att enti on.
I nstead, ESC improves the poss ibility of keeping
188
the veh icle unde r control and on the road dur ing
extreme maneuve rs by using the dr iver's stee ring
i nputs to help keep the vehicle going in the in ­
tended direction. If yo u are traveling at a speed
that causes you to run off the road before ESC
can p rov ide any assistance, you may not experi­
ence the benefits of ESC.
ESC is switc hed on all the time. In certain s itua­
tions when you need less tracti on, you can switch
off ASR by press ing the button
[ru c:> page 189,
fig . 178. Be sure to sw itch ASR on aga in when
you no longer need l ess traction.
The following systems are integrated in the ESC:
Anti -lock braking system (ABS )
ABS prevents the whee ls from locki ng when brak ­
i ng . T he veh icle can st ill be stee red even during
hard braking. App ly steady pressure to the brake
pedal. Do not pump the pedal. A puls ing in the
brake pedal indicates that the system is acting to
stab ilize the veh icle.
Brake assist sy stem
The bra ke ass ist system can decrease braking dis­
tance. It increases bra king power when the driver
presses the brake peda l quickly in emergency sit­
uat ions. You must press and hold the b rake peda l
u nt il the dange rous situat io n is over . In vehicles
with adaptive cruise co ntro l*, the brake ass ist
system is more sensitive if t he d ista nce detected
to t he veh icle a head is too sma ll.
Anti-slip regulation (ASR)
ASR red uces eng ine power when the drive wheels
begin spin ning and adapts the force to the road
cond it ions . Th is makes it eas ier to sta rt, acce ler­
ate a nd dr ive up incl ines.
Electronic differential lock (EDL)
EDL applies t he brakes to a whee l that starts
sp inning a nd tra nsfe rs the d rive power to the
othe r drivi ng whee ls. This function is not ava ila­
ble at hig he r speeds.
In extreme cases, EDL automatically sw itches off
to keep the brake o n the braked whee l from over­
hea ting. The vehicle is st ill work ing cor rect ly. EDL ..,.

will switch on again automatically when
conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the steering in critical situa­
tions.
Selective wheel to rque control
Selective wheel torque control is used when driv­
ing on curves . The front wheel on the inside of
the curve or both wheels on the i nside of the
curv e are braked selectively as needed . This al­
lows more precise dr iving in curves.
Automatic post-collision braking system
The "Automatic post-collision braking system"
can help to reduce the risk of sliding and of other
collis ions after an accident. If the airbag control
module detects a coll is ion above a ce rtain veh icle
speed, the vehicle is braked by the ESC.
The vehicle does not brake automatically if:
- the driver presses the acce lerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the braking force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electri­
ca l system are not functioning.
Switching on/off
Intelligent Technology
A WARNING ,-
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pe ry or wet roads. If the systems begin act­
ing to stabilize your vehicle, you should im­
mediately alter your speed to match the
road and traffic conditions. Do not let the in­
creased safety provided tempt you into tak­
ing risks. This could increase your risk of a
collis ion.
- Please note the r isk of a collision increases
when driving fast, especially thro ugh curves
and on slippery or wet roads, and when driv­
ing too close to objects ahead. The ESC and its integrated systems cannot always pre­
vent collisions· there is still a risk of acc i­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
i n crease the r isk of a coll ision .
(j) Tips
-ABS and ASR only function correctly when
all four wheels are equipped with identical
tires. Different tire s izes can lead to a reduc­
tion in engine power .
- You may hear noises when the systems de­
scribed are working.
ESC turns on automatically when you start the engine .

The following examples are unusual situations
where it may make sense to switch sport mode
on in orde r to allow the wheels to sp in:
- Rocking the vehicle to free it when it is stuck
- Driving in deep snow or on loose ground
- Driving with snow chains

All wheel drive (quattro)
App lies to vehicles : with all wheel drive
In all wheel drive, all four wheels are powered .
General information
In all whee l dr ive, the dr iv ing power is divide d be­
tween all four whee ls. Th is happens automat ic al­
l y depending on yo ur driv ing behavior as well as
the cur rent roa d conditions . Refer to r=>
page 188,
Electronic Stabilization Control (ESC).
A cente r d iff eren tial distribu tes the d riving power
variably to the fron t and rear ax le . I t works to ­
gether w it h select ive whee l torq ue control, which
activates when driving throug h curves
<=> page 189. With the sport differential*, power
distribution to the rear wheels is variable a nd can
be adjusted with drive select<=>
page 101 .
The all whee l drive concept is designed for high
engine power . Yo ur vehicle is exceptionally pow ­
erfu l and has excellent driving characterist ics
bot h under normal driving conditions and on
snow and ice . Always read a nd follow safety pre­
ca utions
<=> ,& .
Winter tires
By using all whee l dr ive, your ve hicle has good
forward motion with sta ndard t ires in winter con­
dit ions . However, in winter we recommend usi ng
winter or all seaso n tires on a ll fou r wheels, be­
cause this will improve the braking eff ect.
Snow chains
If there are snow chain laws, snow chai ns m ust
also be used o n ve hicles with all wheel drive
r=> page 248 , Snow chains .
Replacing tires
For vehicles with a ll wheel drive, o nly wheels with
the same rolling circum ference should be used.
