tem malf unct io n. Wait until the air suspen­
sion system has restored normal gro und clear­
ance . Otherwise, conditions such as an uneven
road surface can lead to vehicle damage.
~/ !f Safety systems
The fl (USA models) !fll (Canada models) in­
dicator 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
fl (USA models)
Jfll (Canada models)
indicator light does not go out, or if it illumi­
nates while you are driving, or if it starts to
blink, then there is a malfunction somewhere
in the system. If the light does not illuminate
when you switch the ign ition on, th is also
mea ns there is a malfunct io n.
A WARNING
If you have a ma lfunction in the safety sys­
tems, contact your authorized Audi dealer immediately. Otherwise the safety sys­
tems may not work properly in an acc i­
dent.

(ESC)
This warning/indicator light monitors the
Electronic Stabilization Control .
When you switch the ignition on, the indicato r
light
G1 turns on briefly to check the function.
If the
G1 indicator lamp blinks while dr iv ing,
the ESC or ASR (Anti-Slip Reg ulation) is active­
ly reg ulat ing.
If the
Ji1 indicator lamp illuminates, the sys­
tem has switched the ESC
off.
If the indicator light II turns on, the ESC was
switched to ESC sport mode with the button

You c an a lso a djust the setti ng according to
your p re ferences in the
Individual mode . F o r
examp le, you ca n combine settings such as a
sporty en gine t uning with comfortab le steer­
ing.
A WARNING
Improper use of the A udi drive select can
cause collisions, ot her acc idents and se ri­
ous pe rsonal injury.
Description
The vehicle setup in each mode depends on
the veh icl e's featu res. The engine, t ransm is­
sion, stee ring, reve rsible sa fe ty belt tension­
e rs a nd adap tive air su spension are alw ays in­
volved.
Engine and transmission
Depending on the mode, the e ng ine and the
tra nsmission respond quic ker or i n a more bal­
an ced manne r to acce le rator pedal move­
men ts. In the sporty dyn ami c mode, the
tra nsmission sh ifts at highe r RP Ms.
Air suspension*
The adaptive air suspens ion/adaptive air sus­
pension spor t*
(Air suspen sion in the MM I) is
a n e lec tronic ally con trolled air suspension and
da mpi ng sys tem. They are adjus ted depend­
ing on the se lected driving mode, the drive r's
steeri ng, braking an d acceleration input and
the road s urface, ve hicle speed and load. A
sporty setting is generally used in ve hicles
with adaptive air suspension sport*. T
he veh icle clearance varies depending on the
se lected mo de an d the speed .
T he highway setti ng is a ct ivated automatic ally
whe n you dr ive above 7 5 mph (120 km/ h) fo r
more than
3 0 seconds in the Auto or Dynamic
mode. The gro und clea rance is increased a uto ­
matically if the speed drops below
44 mph
(70 km/h) for more than 120 seconds.
Steering
T he s teer ing adap ts in terms of s teer ing effor t
and steering ratios . Indirect stee ring that
moves easily, like the steer ing in comfo rt
mode, is best suited to long drives on a high­
way. In contrast, dynamic mode provides sporty, direct steer ing .
Sport differential*
As a component of the all whee l drive system
(quattro ®)
r=:> page 201, th e Sport differen­
t ia l* distributes the driving powe r to the rear
axle depending on the situation. The distr ibu­
t ion of power va ries depe nding on the select­
ed mode, from balanced (comfort) to agile
(dyna mic) . Th e goa l is a high leve l of agility
and ability to acce le rate on cu rves . Th e vehicle
is ve ry re sponsive to st eer ing.
Curve light*
The curve light adapts to driving on curves .
T he pivo ting act io n and the lighting are also
adapt ed to the mode .
Adaptive cruise control*
The behav ior when accelerating can be adjust­
ed from comfortab le to sporty, depending on
the drive select mode. Adaptive cru ise cont ro l
also responds to th e dr iv ing behavior o f th e
vehicle a head in a mo re co nse rvative o r sporty
man ne r.
Engine sound*
The sound of the eng ine is adapted to the se­
lected mode and ranges from sub tle to sporty . .,.

(D Note
-Make sure there is enough clearance
above and below the veh icle 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 iving modes,
which can affect clearance .
- When t ransporting the veh icle on a car
carr ier, tra in, ship or by other means, on­
l y tie the veh icle down at the runni ng
su rface of the tires, which is the outer
ci rcumference . Secur ing the vehicle at
the axle components, s uspension struts
or tow ing eyes is not pe rm itted because
the pressu re in the air suspension struts
can change during transport. The vehicle may not be secured sufficiently if this
happens.
- If you are going to tow a trailer, you
must activate the trailer operation mode
<=> page 209.
{!) Tips
- In some models, the maximum vehicle
speed can only be reached in the
Auto
and Dynami c modes.
- Selecting the
Dynami c mode results in
spo rty sh ifting character istics. The S
gear posit ion engages automatically.
- In vehicles with sport differential", the
Dynami c mode is deactivated when tow­
i ng a trailer.

ESC includes and/or works together with the
anti-lock brake system (ABS) , brake assist sys ­
tem, anti -slip regulation (ASR) , electronic dif­
ferential lock (E DL) and e lectronic interaxle
d ifferential lock*. ESC is swi tched on all the
time. In certain situat ions when you need less
traction , you can switch off ASR by pressing
the button
[ru ~ fig . 181 . Be sure to switch
ASR on again when you no longer need less
traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The vehicle can still be steered even during hard braking . Apply steady pres­
sure to the brake pedal. Do not pump the ped­
al. A puls ing in the brake pedal indicates that
the system is he lping you to brake the vehicle.
Brake assist system
The brake assist system can decrease brak ing
d istance.
It increases braking power when the
driver presses the brake pedal quickly in emer­
gency situations. You must press and hold the
brake pedal until the situation is over . In
vehicles with adaptive cruise control* , the
brake assist system is more sensitive if the
d istance detected to the vehicle ahead is too
small.
Anti-slip regulation (ASR)
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
s tart, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinn ing and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-whee l drive*. This function is available up
to about 75 mph (120 km/h).
I n extreme cases , EDL automatically switches
off to help keep the brake on the braked wheel
from overheating. EDL wi ll switch on again au­
tomatically when conditions have returned to
normal.
Intelligent technology 197
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
whee l drive) or the se lective wheel torque
cont rol (all-wheel dr ive) operates when dr iv­
ing through curves . The front wheel on the in­
s ide of the curve or both wheels on the inside
of the curve are braked selectively as needed .
T his min imizes sliding in the front wheels and
allows for more precise driving through
curves . Th e applicable system may no t acti­
vate when driv ing in wet or snowy conditions.
A WARNING
-
-ESC, ABS, ASR, EDL and the electronic in­
teraxle differential lock function* cannot
overcome the laws of physics. This is es­
pecially important on slippery or wet
roads . If the systems begin acting to sta­
bilize your vehicle, you should immedi­
ately change your speed to match the
road and traffic conditions. Do not let
the increased safety provided by these
systems tempt you to t.;1ke risks. Doing
so will increase the risk o f a loss of vehi­
cle control, collision and serious personal
injuries.
-Always adapt your speed to road, traffic
and weather conditions . The risk of los­
ing control of the vehicle increases when
driving too fast, espec ially through
curves and on slippery or wet roads, and
when dr iving too close to vehicles up
ahead . ESC, ABS, the brake assist sys­
tem, EDL, ASR and the elec tronic inter­
axle differential lock function* cannot
prevent collisions .
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve -
hicle control. .,.

For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you.
It is becoming increas ingly more and more
d iff icu lt to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be
removed before you are able to get to the
bu lb. This applies especially to the light bulbs
in the front of your car which you can on ly
reach throug h the engine compartment.
Sheet metal and bulb ho lders can have sharp
edges that can cause serious cuts, and parts must be correctly taken apart and then prop ­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you, since your dealer has the proper tools,
the correct bulbs and the expertise .
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be identified
by the high voltage sticker.
LED headlights* require no maintenance.
Please contact your authorized Audi dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head- light bulbs can cause serious personal in­
jury and death.
- Xenon bulbs are pressurized and can ex­
plode when being changed.
- Changing Xenon lamps requires the spe­
cial training, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bulbs in gas discharge lamps.
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work­
shop. Serious personal injury may result
from imprope rly performed work.
(D Tips
- If you must replace the light bulbs your­
self, always remember that the eng ine
compartment of any vehicle is a hazard­
ous area to work in. A lways read and
heed all WARNINGS ~
page 224, Engine
compartment~ &..
-It is best to ask your authorized Audi
dealer whenever yo u need to change a
bulb .
