and the electronic differential lock (EDL) .
The warning/indicator light fJ]l (USA models)/
ti] (Canada models) will come on for a few sec­
onds when the ignition is switched on. The light
will go out after an automatic check sequence is
completed.
There is a malfunction in the ABS when:
-The warning/indicator light does not illuminate
when you switch the ign it ion on.
- The warning/indicator light does not go out af­
ter a few seconds.
- The warning/indicator light illuminates while driving .
The ESC indicator light also illuminates if there is
a ma lfunction in the ABS . The message

A WARNING
-If the fJ]l (USA mode ls)/ tl] (Canada mod­
els) warn ing light does not go out, or if it
comes on while dr iv ing, the ABS system is
not working prope rly . The vehicle can then
be stopped only with the standard brakes
(without ABS) . Yo u will not have the protec­
tion ABS provides. Contact your authorized
Audi dea ler as soon as possible.
- USA models: If the 1111 warning light and
the
fJ]l warning light come on together, the
rear whee ls cou ld lock up first under hard
braking. Rear whee l lock-up can cause loss
of vehicle control and an accident. Have your
veh icle repa ired immediately by your au­
thorized Audi dealer or qualified workshop.
Drive slowly and avoid sudden, hard brake
applications .
-Canada models: If the brake warning light
• and the ABS warning light
ti] come on
together, the rear wheels could lock up first
under hard bra king. Rear wheel lock-up can
cause loss of vehicle contro l and an acci­
dent . Have your vehicle repai red immediate­
ly by your authorized Audi dealer or quali­
fied workshop . Drive slow ly and avoid sud ­
den, hard brake applications.
tli I !i: Safety systems
The fl (USA models) ;fll (Canada models) indi­
cator light monitors the safety systems (e.g. a ir­
bags, pretensioners) and illuminates for a few
seconds each time you switch the ignition on .
-
If the II (USA models)/E,I (Canada mode ls) in­
dicator light does not go out, or if it illuminates
wh ile you are driving, or if it starts to blink, then
there is a malfunction somewhere in the system.
If the light does not illum inate when you sw itch
the ignition on, this also means there is a mal­
function.
A WARNING ~
If you have a malfunction in the safety sys-
tems, contact your a uthorized Audi dea ler im­
mediately. Otherwise the safety systems may
not work properly in an accident.

Driving settings
Introduction
Applies to veh icles: w ith Audi drive select
Drive select provides the possibility to experience
d ifferent types of vehicle settings in one vehicle.
F or instance, using the three
Comfort, Auto and
Dynamic modes, the driver can switch from a
sporty to a comfortable driving mode with the press of a button.
Addit ionally, in vehicles with MM I*, the vehicle
setup for
Individual* mode can be customized by
you. This makes it possible to combine settings
such as a sporty engine tuning with comfortable
steering .
A WARNING
Improper use of the Audi drive select can
cause collisions, other acc idents and serious
personal injury.
Description
Applies to veh icles: w ith Audi dr ive select
-
The vehicle setup in each mode depends on the
veh icle's features . However, the engine, automat­
ic transmission* and steering are always involved.
Engine and automatic transmission*
Depending on the mode, the engine and the au­
tomatic transmission respond quicker or in a
more balanced manner to accelerator pedal
movements. In the sporty dynamic mode, the au­
tomatic transmission shifts at higher RPMs.
Steering
The steering adapts in terms of steering effort
and steering ratios. Indirect steer ing 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 stee ring.
The follow ing applies to vehicles with dynam ic
steer ing*: the steering ratio changes based on ve­
h icle speed in order to maintain optimum steer­
ing effort for the dr iver at all times. This sets the
s teer ing to be less sensitive at higher speeds in
102
order to provide improved vehicle control. At re ­
duced speeds, however, steering is more direct in
order to keep the steer ing effort as m inima l as
possib le when the driver is maneuver ing the vehi­
cle. At low and average speeds, dynam ic steering
additionally provides more responsive steering
performance.
Adaptive dampers*
The adaptive dampers* use sensors to record in­
formation regarding steering movements, brak­ ing and acceleration operations by the driver,
road surface, driving speed, and load. This makes
i t possible to adapt damp ing to the driving situa­
tion virtually in real t ime . Drive select also makes
i t possible to sat isfy the desire fo r sporty suspen­
s ion (Dynamic) and comfortable suspension
(Comfo rt) without giving up ba lanced tuning (Au­
to).
Sport differential*
As a compone nt of the all whee l dr ive system
(quattro)
<> page 174, t he sport differential* dis­
tributes the driving power to the rear axle de­
pending on the situation. The distribution of
power varies depending on the mode selected.
The goal is a high level of agility and ability to ac­
ce lerate on curves. The vehicle is very responsive
to steering.
Audi adaptive cruise control*
The behavior 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.
Engine sound*
The sound of the engine is adapted to the select­
ed mode and ranges from subtle to sporty.
(D Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto and
Dynamic modes.
- For vehicles with an automatic transmis-
sion, se lecting the
Dynamic mode results in 1111-

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 certain
d ifficult driving situations, including when the ve­
h icle is beginn ing to sp in (yaw) out of control and
he lps you to ge t the vehicle back u nder cont rol by
selectively braking the wheels, and/or reducing
engine power and providing steering assistance
to help hold the vehicle on the driver's intended
course. The indicator light
liJ in the instrument
cluster blinks when ESC is taking action to help
you control the veh icle.
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
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 that is s uddenly cov ­
ered wi th wa ter, s lush or snow, ESC cannot per­
form the same way it wou ld on the d ry surface . If
the vehicle hydroplanes (rides on a cushion of wa ­
ter instead of the 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 braked or steered. Dur ing fast
cornering, particula rly on w inding roads, ESC
cannot a lways deal as effect ively with d iff icu lt
d riving situat ions than at lower speeds. When
towing a trailer, ESC is not able to he lp yo u regain
con trol as it wou ld if yo u were not towing a trail­
er .
A lways adjust you r speed and dr iving style to
road, traffic and weather conditions. ESC cannot
override the vehicle's physical limi ts, increase the
170
available traction, or keep a vehicle on the road if
road departure is a result of driver inattention .
Instead, ESC improves the possibility of keeping
the ve hicle under control and on the road dur ing
extreme maneuvers by using the dr iver's steering
i nputs 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 p rov ide any assistance, you may not expe ri­
ence the benefi ts of ESC.
ESC is switched o n all the time. In ce rtain s itua­
tions when you need less traction, you can switch
off ASR by p ress ing the button [!]¢
page 171,
fig. 153 or ¢page 171, fig. 154. Be s ure to
swi tch ASR on again when you no longe r need
l ess traction .
The following system s are integrated in the ESC:
Anti- lock braking s ystem (ABS )
ABS prevents the wheels from locki ng up when
braking. The vehicle ca n still be steered even dur­
i ng hard braki ng . Apply steady pressure to the
brake pedal. Do not pump t he pedal. A pu lsing in
t h e b ra ke peda l ind icates that the system is he lp­
i ng yo u to b ra ke the vehicle.
Brake assist system
The brake ass ist system can decrease brak ing dis ­
ta nce. It increases braking power when the d river
presses the bra ke peda l quickly in emergency sit­
u at ions. You must press and hold t he b ra ke peda l
u nt il t he s ituation is ove r. In vehicles with adap­
tive cru ise contro l*, the bra ke assist system is
more sensitive if the distance detected to the ve ­
hicle ahead is too sma ll.
Anti-slip regulation (ASR )
ASR reduces eng ine power when the d rive wheels
begin to spi n and adap ts the force to the ro ad
cond it ions . This makes it eas ie r to start, acce le r­
ate and drive up hills.
Electronic differential lock (EDL)
The EDL bra kes whee ls that a re spinn ing and
t ransfers the dr ive power to the othe r drive wheel
o r whee ls if the ve hicle is equippe d wi th a ll-wheel
drive*. T his function is not available at higher
speeds .

M N

rl I.O
"' N
"' rl
In extreme cases, EDL a utomatica lly switches off
to help keep the brake on the braked whee l from
overheating. EDL w ill switch on again automati ­
cally when conditions have returned to normal.
Steering re commendat ion
The ESC helps to stabilize the ve hicle by chang ing
the steering torque.
I n vehicles with dynamic steeri ng*, ESC also
h e lps to stabilize the steering in critical s itua­
tions .
Electronic interaxle differential lock* /
sel ectiv e wheel torque control*
The electron ic in teraxle d iffe ren tial lock (front
wheel drive) or the selective wheel torq ue contro l
(all wheel drive) operates when driving through
curves. The front whee l on the ins ide of the cu rve
or both whee ls on the inside of the curve are
braked selectively as needed. Thi s allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
ci al ly impo rtant on slippe ry or wet roads. If
the sys tems begin acting to stabilize your
Switching on/off
Smart Technology
veh icle, you shou ld immediately change
your speed to matc h the road and traffic
conditions. Do not let the increased safety
provided by these systems tempt you to
take risks . Do ing so will increase the risk of a
loss of vehicle control, collision and serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol of the vehicle inc reases when dr iving
too fast, espec ially through curves and on
slippery or wet roads, and when dr iving too
close to vehicles up ahead . The ESC and its
integrated systems cannot a lways prevent
coll isions -there is sti ll a risk of accidents!
- Always accelerate with special care on even,
smooth su rfaces such as those that are wet
or covered with ice and snow. The drive
wheels can spin even with these assistance
systems that can not always help to reduce
the risk of loss of vehicle cont rol.
{!) Tips
-ABS and ASR only work correct ly when a ll
four wheels are equipped w ith ident ica l
tires. Different tire sizes 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 ESC is designed to function in levels. Depend­
i ng on the level that is selected, the stabilization
function o f the ESC is limited or switched off . The
