tl'l.l !f Safety systems
The II (USA models)/S,I (Canada mode ls) in­
d icator light monitors the safety systems (e .g.
a irbags, pretensioners) and illuminates for a
few seconds each time you switch the ignition
on.
I f the
II (USA mode ls)/ S,I (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 ma lfunction somewhere
in the system.
If the light does not illuminate
when you switch the ignition on, this also means there is a malfunction.
A WARNING
If you have a malfunction in the safety sys­
tems, contact your author ized Audi dealer
immediate ly. Otherwise the safety sys­
tems may not wo rk properly in an acci­
dent.
& Central indicator light
I f the indicator light . or II turns on, check
the message in the instrument cluster.

If the J,.J indicator light blinks wh ile driving,
the ESC or ASR (Ant i- S lip Regulation) is active ­
ly regulating .
If the
Ji! indicator light turns on, the system
has sw itched the ESC off. In this case, you can
switch the ignition off and then on to switch
the ESC on again . The indicator light turns off
when the system is functioning fully .

96 Audi drive select
Audi drive select Driving settings
Introduction
Audi drive select makes it possible to experi­
ence different types of vehicle settings in one
vehicle. The driver can select three
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
example, you can combine settings such as a
sporty engine tuning with comfortable steer­
ing.
A WARNING
Improper use of the Audi drive select can
cause collisions, other accidents and seri­
ous personal injury.
Description
The following systems are affected by drive
select:
Engine and transmission
Depending on the mode, the engine and the
transmission respond quicker or in a more bal­
anced manner to accelerator 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 controlled 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 surface, vehicle speed and load. A
sporty setting is generally used in vehicles
with adaptive air suspension sport*.
The vehicle clearance varies depending on the
selected 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
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 steering 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 steering .
The 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 sensitive at higher
speeds in order to provide improved vehicle
control. At reduced speeds, however, steering
is more 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 additionally pro­
vides more responsive steering performance.
Adaptive dampers*
The adaptive dampers* use sensors to record
information regarding steering movements,
braking and acceleration operations by the
driver, road surface, driving speed, and load.
This makes it possible to adapt damping to
the driving situation virtually in real time.
Drive select also makes it possible to satisfy
the desire for sporty suspension (Dynamic)
and comfortable suspension (Comfort) with­
out giving up balanced tuning (Auto) .
Sport differential*
As a component of the all wheel drive system
(quattro)
c::;; page 193, the Sport differential*
distributes the driving power to the rear axle
depending on the situation. The distribution
of power varies depending on the selected
mode, from balanced (comfort) to agile (dy­
namic). The goal is a high level of agility and

Raising/lowering the
vehicle
App lies to vehicles: with adaptive air suspension
Raising the vehicle
You can raise your vehicle temporarily, for ex­
ample to drive over a tall curb .
• Se lect the following in the MMI : ICAR !func­
tion button
> Raise contro l button.
• Wait for the arrows in the display to stop
blinking and the vehicle to reach its final po­
s it ion.
Lowering the vehicle
• To lower the vehicle, select the following in
the MMI: ICARI function button
> Lower con­
trol button. •
Wait for the arrows in the display to stop
blinking and the vehicle to lower comp lete­
ly.
(D Note
- Remember that your vehicle is not suita­
ble for driv ing offroad even when it is
raised . There is not enough ground clear­
ance.
- If the vehicle is raised, it wi ll lower auto­
matically when driving 62 mph (100 km/
h) or faster.
Driver messages
Air suspension : vehicle currently too low.
Level control running
Air suspension: vehicle currently too high.
Level control running
T he dr iver message switches off when the lev­
el control process is complete.

188 Intelligent technology
Anti-slip regulation (ASR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road conditions. This makes it easier to
start, accelerat e and drive up hills .
Electronic differential lock (EDL )
The ED L brakes wheels that are spinn ing and
transfers the drive powe r to the o ther wheels.
This function is not availab le at higher speeds.
I n extreme cases , ED L automat ica lly switches
off to help keep the brake on the braked whee l
from ove rheating. EDL wi ll sw itch on aga in au­
tomatically when conditions have returned to
norma l.
Steering recommendation
The ESC helps to stabilize the ve hicle by
changing the steering to rque.
In vehicles with dynam ic steering*, ESC also
he lps to stabilize the stee ring in critical s itua­
tions.
Selective wheel torque control
Selective wheel torque control is used when
driving on curves . The front wheel on the in­
side of the curve o r both wheels on the inside
of the curve are braked selective ly as needed.
This a llows more prec ise driving in curves. The
appl icable system may no t activ ate when driv­
ing in wet or snowy condi tions .
A WARNING
- The ESC and its integrated systems can­
not overcome the lim its posed by natural
physical laws. This is especia lly impor- tant on slippery or wet roads
. If the sys­
tems beg in acting to stabilize your vehi­
cle, you should immediately change your
speed to match the road and traffic con­
ditions . 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 veh icle contro l, collision and
serio us pe rsonal inj uries.
- Always ad apt your speed to road, traffic
a nd wea ther conditions. The risk of los­
ing con trol of the vehicle increases when
driving too fast, especially through
curves and on slippe ry or wet roads, and
when dr iv ing too close to vehicles up
ahead . The ESC and its integrated sys­
tems cannot a lways prevent collisions -
there is still a risk of acc idents!
- 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 w ith
these assistan ce sys tems that cannot al­
ways he lp to re duce the risk of loss of ve­
h icle control.
(D Tips
- ABS and ASR o nly wo rk correctly when
all four wheel s are equipped with identi­
c al tires . D iffe ren t tire sizes can lead to a
reduction in engine power.
- Yo u may hear noises when the systems
descr ibed are working.
- If the ind icator lig ht
BJ or rJlll (USA
mode ls)/ l§J (Can ada models) appears,
t here may be a malfunction ¢

Driving with your
quattro
With all-wheel drive, all four wheels are driv­
en .
General information
With all-wheel drive, power is distributed to
all four wheels . This happens automatically
depending on your driving style and the road
conditions at the time . See also ¢
page 187.
A center differential distributes the driving
power variably to the front and rear axle. It
works together with selective wheel torque
control, which activates when driving through
curves ¢
page 188 . With the sport d ifferen­
tial*, power distribution to the rear wheels is
va riable and can be adjusted with drive select
¢page 96.
The all-wheel drive concept is designed for
hi gh engine power. Your vehicle is exception­
ally powerful and has exce llent dr iving charac­
teristics both under normal driving conditions
and on snow and
ice. Always read and follow
safety precautions ¢.& .
Winter tires
When driving in the w inter , your ve hicle with
all-wheel drive has an advantage, even with
regular tires. In winter road conditions it may
be advisable to mount winter tires (or all-sea­
son t ires) for improved driveability and brak­
ing: these tires must be mounted on
all four
wheels. See also ¢ page 252, Winter tires.
Tire chains
Where tire chains are mandatory on certain
roads, this normally a lso applies to vehicles
with a ll-wheel drive¢
page 253, Snow
chains.
Replacing wheels/tires
Vehicles w ith all-wheel drive must always
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 245, New tires and replacing
~ tires and wheels . 1.1'1 ,...., 1.1'1 ,....,
Intelligent technology 193
Off•Road driving?
Your Audi does not have enough g round clear­
ance to be used as an off-road vehicle.
It is
therefore best to avoid rough tracks and un ­
even terrain as much as possible. Also refer to
¢page 197.
A WARNING
Always adjust your dr iv ing to road and traf­
fic conditions. Do not let the extra safety
afforded by all-wheel drive tempt you into
taking extra risks.
- Although the all-wheel drive is very ef­ fective, always remember that braking
capacity is lim ited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
drive too fast because the front wheels
could begin to slide on top of the water
(aquaplaning) . If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive veh icle. Always drive at
speeds which are su ited to the road con­
ditions - risk of crash.
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine .
If a vehicle with a conventiona l energy system
is not driven for a long period of tim e, the bat­
tery is discharged by idling current consumers
(e.g . immobilizer). In certain circumstances it
can resu lt in there being insufficient energy
available to start the eng ine.
Intelligent energy management in your vehi­
cle handles the distribution of e lectrica l ene r­
gy. Starting ability is markedly improved and
the life of the battery is extended .
