¢page 157, MMI settings.
-If driving in dynamic mode is desired, this
mode
must be selected before hitching up
the trailer and before adjusting the tongue
weight. However, note that your vehicle is lowered and ground clearance is reduced.
- If you have to drive under difficult road con­
ditions, you can select offroad or lift mode,
after hitching up the trailer or after adjust­
ing the tongue weight.
- If the vehicle is at
normal level, and you se­
lect offroad mode while traveling at speeds
higher than 22 mph (35 km/h), the vehicle
will not be raised. Offroad mode will appear as the active mode in the MMI Display.
- If the vehicle is in offroad mode at
high level

190 Airbag sys tem
-Always make sure the forward-facing
seat has been des igned and certified by
its manufacturer for use on a front seat
with a passenger front and side airbag .
- Never put the forward-facing child re­
straint up aga inst or very near the instru­
ment panel.
- Always move the passenger seat into its
rearmost position in the seat's fore and
aft adjustment range, as far away from
the a irbag as poss ible, before insta lli ng
the fo rward-facing chi ld restraint. The
b ackres t must be adjus ted to an upr igh t
posit io n.

Advanced Airbag System components
The front passenger seat in your vehicle has a lot of very important parts of the Advanced
Airbag System in it. These parts include the
weight-sens ing mat, sensors, wiring, brack­
ets, and more . The fu nction of the system in
the front passenger seat is checked by the
e lectronic control u nit when the ignit ion is on.
The control unit mo nitors the Advanced Air­
bag Sys tem and turns the airbag indicator
light on when a ma lfunction in the system
components is detected . The function of the
ai rbag ind icator light is described in greater
detai l below. Because the front passenger
seat contains important parts of the Ad­
vanced A irbag System, you must take care to
prevent it from be ing damaged . Damage to
the seat may prevent the Advanced A irbag for
the front passenger seat from doing its job in
a cra sh .
The front Advanced Airbag System
consists of the following:
- Crash senso rs in the front of the veh icle that
measu re ve hicle ac celera tion/de ce le ra ti on
to provide info rm ation to the Advanced Air­
bag System abo ut the severity of the crash . -
An elect ronic contro l unit, with integrated
crash sensors for front and side impacts .
The control un it "decides" whether to fi re
the front a irbags based on the informat ion
received from the crash sensors. The contro l
un it also "decides" whether the safety belt
prete nsioners shou ld be act ivated .
- An Advanced A irbag w ith gas generator for
the dr iver inside the stee ring wheel hub .
- An Advanced A irbag w ith gas generator in­
side the instrument panel for the front pas­
senge r.
- A we ight-sensing mat under the up ho lstery
padding of the front passenger seat cushion
that measures the total weight on the seat .
The informat io n registe red is sent continu­
ou sly to the elec troni c con tro l unit to regu ­
la te deployment of the front Advanced Air­
bag on the passenger side .

Important safety instructions on
monitoring the Advanced Airbag System
_&. WARNING
An airbag system that is not functioning
prope rly cannot provide supplemental pro­
tect ion in a frontal crash.
- If the airbag indicator light
c::> page 16
comes when the vehicle is be ing used,
have the system inspected immediately
by you r authorized Aud i dea ler.
It is pos­
sible that the airbag will inflate when it
is not supposed to, or w ill not inflate
when it should .
_&. WARNING
If the front airbag inflates, a child witho ut
a child restraint, or in a rearward-facing
child safety seat, or in a forward-facing
child restraint that has not been properly
installed will be seriously injured and can
be killed .
- Even though your veh icle is equipped
with an Advanced Airbag System, make certain that all children, especially 12
years and younger, a lways ride on the
back seat properly restrained for their
age and size.
- Always install forwa rd or rear-facing
child safety seats on the rear seat -even
with an Advanced Airbag System. -
If you must install a rearward-facing
child safety seat on the front passenger
seat because of exceptional c ircumstan­
ces and the
PA SS ENGER AIR BA G OFF
light does not appear and stay on, imme­
diate ly install the rear-facing child safety
seat in a rear seat ing pos ition and have
the airbag system inspected by your au­
thorized A udi dealer.
- A tight tether or other strap on a rear­ ward-facing child restraint attached to the front passenger seat can p ut too
m uch pressure on the weight-sensing
mat in the seat and register more weight
than is actually on the seat. The heavier
weight registered can make the system
work as though an adult were on the seat
and deploy the Advanced Airbag when it
must be suppressed causing ser ious or
even fata l injury to the ch ild.
- If, in exceptional circumstances, you
must install a forward-fac ing ch ild re­
straint on the front passenger seat, al ­
ways move the seat into its rearmos t po­
sition in the seat's fore and aft adjust­
ment range, as far away from the airbag
as possible. The backrest must be adjust­
ed to an upright position. Make sure that
the
PASSEN GER AIR BAG OFF light
comes on and stays on all the time when­
ever the ignit ion is switched on .
_&. WARNING
r-
- If the PASSENGER AIR BAG OFF light
does not go out when an adult is sitting
on the front passenger seat after taking
the steps described above, make sure the
adu lt is properly seated and restra ined at
one of the rea r seat ing pos itions.
- Have the airbag system inspected by
your author ized Audi dealer befo re trans­
port ing anyone on the front passenger
seat.

Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers fo r the express purpose of capturing
data for retrieval after an accident or crash
event . EDRs are sometimes ca lled "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDRs that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
A lthough your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts .
These electronic contro l modules also record
vehicle-related data during normal vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only
be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) rein­
forces driver safety. It reduces the risk of slip ­
p ing and improves driving stability. ESC de­
tects cr itical s ituations such as the vehicle oversteering and
understeering or the wheels
spinning . The vehicle is stabilized by applying
the brakes or reducing engine torque . Once
the ESC is active, the indicator light
G1 blinks
in the instrument cluster.
ESC includes the anti-lock brake system (ABS),
brake assist system, anti-slip regulation
(ASR), electronic differential lock (EDL) and
hill descent control.
Anti-lock brake system (ABS)
ABS prevents the whee ls from locking up
when braking. The vehicle can still be steered
even during hard braking. App ly steady pres­
sure to the brake pedal. Do not pump the ped­ al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle .
Brake assist system
The brake assist system can decrease braking
distance. 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
distance 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 conditions. This makes it easier to
sta rt, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other wheels .
This function is available up to about 60 mph
(100 km/h) .
In extreme cases, EDL automatically switches
off to help keep the brake on the braked wheel
from overheat ing. EDL will switch on again au­
tomat ically when conditions have returned to
normal.

Replacing wh eels/ tire s
Vehicles w ith all-wheel drive must a lways
have tires of the same size. Also avoid tires
with different tread depths. For details see
page ¢
page 284, New tires and replacing
tires and wheels .
.&_ WARNING
Always adjust your driving to road and traf­
fic conditions . Do not let the extra safety
afforded by all-wheel dr ive tempt you into
tak ing extra risks.
-Although the all-wheel dr ive is very ef­
fective, always remember that braking
capacity is limited by t ire traction . You
sho uld therefore not dr ive at excessive
speeds on icy or s lippery road surfaces.
- On wet road su rfaces, be careful not to
dr ive too fast because t he front wheels
cou ld beg in to s lide on top of the wa ter
(aquaplaning). If this sho uld occ ur, you
w ill have no warning from a sudden in­
crease in engine speed as with a front­
whee l drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of c rash.
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.
I f a vehicle w it h a conventional energy system
i s not driven for a long pe riod of time, the bat­
tery is disch arged by idling c urrent cons umers
(e .g. immobilizer) . In ce rtain c ircumstances it
can result in there being insufficient energy
ava ilab le to start the engine .
I n tell igen t energy management in your vehi ­
cle hand les the d istribution of electrical ener ­
gy . Starting abi lity is marked ly imp roved and
the life of the battery is extended.
Int ellig ent technolog y 229
Basica lly, energy management consis ts of
batte ry diagnosi s, idling cur rent manage­
ment
and dynamic energy management.
Battery diagnosis
B attery diagnosis continuously de termines
the state of the battery . Sensors determine
batte ry voltage, battery current and battery
temperature . This determines the current
state of charge and the power of the battery.
Idling current management
Id lin g cur ren t man agement reduces energy
consumption while the vehi cle is standing.
With the ig nition switched off, it controls the
energy supply to the various electrical compo­ nents. Data from battery diagnos is is cons id­
ered.
Depend ing on the battery's state of cha rge,
individual cons umers are gradually turned off
to prevent excessive discharge of the battery
and thus maintain starting capability.
Dynamic energy manag ement
While the vehicle is being driven, dynamic en ­
ergy management distrib utes the energy ge n­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more electrical energy is not being used
than is be ing generated and ensures an opti­
mal state of charge for the battery .
(D Tips
-But even e nergy management cannot
negate the limits of physics. Consider
t hat the powe r and l ife of a bat tery are
l imited.
- If start ing ability is threatened, you are
informed by a warning ¢

230 Intellig ent technol ogy
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the cold time
of year. Abundant electr ical energy is re­
qu ired, but only a little is generated. It is also
cr itical if the e ngine is not running and elect ri­
cal components a re turned on. In th is in­
stance energy is being consumed but none is being generated .
I t is in precisely these situations that you w ill
notice energy management actively regulat­
ing the distrib ution of energy.
Vehicle stand s for an ext ende d period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back o r switched off .
This reduces energy cons umption and main­
tains starting capab ility
over a longer period.
Take into consideration that when you un lock
your ve hicle, some convenience functions,
such as the interior ligh ts or the power seat
ad justmen t, may not be available. The con­
venience functions will be available again
when you turn on the ignition and start the
engine.
With the engine turned off
I f you listen to the radio, for example, with
the eng ine turned off or use other MM I func­
tions, the battery is being discharged .
I f sta rting capability is jeopa rdized due to en­
e rgy consumpt ion, the follow ing warning ap­
pears in the MMI disp lay:
Ple ase s tart engin e, otherwi se system will
s wit ch off in 3 minute s.
The warning ind icates that the system will be
turned off automatically after 3 m inutes .
If
you wish to cont inue us ing the functions, you
have to start the engine.
With the eng in e runnin g
Although e lectrical energy is gene rated when
the vehicle is being driven, the battery can be­
come discharged. This happens mostly when
little energy is being generated and a great
deal consumed and the battery's state of
charge is not optimal.
To bring the energy balance back into equili­ brium, consumers which req uire especially
large amounts of energy are temporar ily cut
back or sw itched off. Heat ing systems in par­
t icular require a great deal of energy. If you
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been tempora rily cut back or switched
off . These systems w ill be available again as
soon as t he energy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T h is is normal and not
a cause for con cern. By inc reas ing engine id le
speed the additional energy required is gener­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the fo llow ing driver message:
(•) low batte ry charge: bat tery w ill be
ch arg ed whil e dri ving
This notificat ion reminds you that the starting
capability of the engine may be lim ited. As
soon as you start dr iv ing again, the battery
will be recharged and the not ificat io n will go
out .
Driver notific ation app ear s a nd goe s out
again
If this driver notification appears after the ig­
nition is turned on or wh ile driving and it goes
out again after a while, the battery has been
adequately recharged. .,.

Selective catalytic
reduction
General information
Applies to vehicles: with diesel engine
On vehicles with selective catalytic reduction,
an urea solution (Ad Blue) is injected into the
exhaust system before a nitrogen oxide cata­ lytic converter to reduce nitrogen emiss ions.
The AdBlue is stored in a separate tank in the
vehicle. The AdBlue usage accounts for ap­
proximately 0.5% to 1.2% of the diesel fuel
that is used.
You must refill the Ad Blue or have it refilled
by your author ized Audi dealer or qualified
workshop as soon as the AdBlue refill mes- sage appears
in the instrum ent cluster
r=>page 255.
.&_ WARNING
-
Failure to heed AdBlue refill information in
the instrument cluster can prevent the ve­ hicle from being started and driven. If the
vehicle cannot be driven and an emergency
arises, personal injury can occur.
- Always have the AdBlue tank refilled well
before the tank runs dry.
(D Tips
- The instrument cluster disp lay ind icates
the distance remaining that can be driv­
