& WARNING
A child in a rearward -facing child safety seat installed on the front
passenger seat will be seriously injured and can be killed if the
front airbag inflates - even with an Advanced Airbag System.
• The inflating airbag will hit the child safety seat or infant
carrier with great force and will smash the child safety seat and
child against the backrest, center armrest, door or roof .
• Always install rear-facing child safety seats on the rear seat.
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional circumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on,
immediately install the rear-facing child safety seat in a rear
seating position and have the airbag system inspected by your
authorized Audi dealer.
• Forward-facing child safety seats installed on the front
passenger's seat may interfere with the deployment of the airbag
and cause serious personal injury to the child.
& WARNING
If , in exceptional circumstances , you must install a forward-facing
child restraint on the front passenger's seat:
& WARNING (continued)
• Always make sure the forward-facing seat has been designed
and certified by its manufacturer for use on a front seat with a
passenger front and side airbag.
• Never put the forward-facing child restraint up against or very
near the instrument panel.
• Always move the passenger seat into its rearmost position in
the seat's fore and aft adjustment range, as far away from the
airbag as possible before installing the forward-facing child
restraint. The backrest must be adjusted to an upright position.
• Make sure that the PASSENGER AIR BAG OFF light comes on
and stays on all the time whenever the ignition is switched on.
& WARNING
To reduce the risk of serious injury, make sure that the PASSENGER AIR BAG OFF light will be displayed whenever a child
restraint is installed on the front passenger seat and the ignition
is switched on .
• If the PASSENGER AIR BAG OFF light does not stay on, perform
the checks described
~ page 220 , "Monitoring the Advanced
Airbag System ".
• Take the child restraint off the front passenger seat and install
it properly at one of the rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on .
• Have the airbag system inspected by your authorized Audi
dealer immediately.
• Always carefully follow instructions from child restraint manu
facturers when installing child restraints.
& WARNING
If , in exceptional circumstances , you must install a forward or
rearward-facing child restraint on the front passenger 's seat:

and ch ild safe ty se at are not be ing transported on t he front
passenger seat;
• make sure that the safety belt tens ion sensor is not blocked.
Shake the safety belt latch on the front passenger seat back and
fort h;
• If a strap or tether is being used to t ie the child safety seat to the
front passenger seat, make sure that it is not so tight that it causes
the weight -sensing mat to measure more weight than is actually on
t he seat.
If the P ASSENGER AIR BA G OFF li ght still doe s not come on and
does not stay on continuous ly (when the ignition is switched on),
• t ake the child restraint off the front passenger seat and insta ll it
properly at one of the rear seat positions. Have the airbag system
inspected by your a uthorized Audi dealer immediately.
• move the child to a rear seat position and make sure that the child
is p roperly rest rained in a c hild restrain t that is appropriate for its
size and age .
T he
PASSENGER AIR BAG OFF light shou ld NO T come on when the
ignition is on a nd an adult is sitt ing in a proper seat ing pos ition on the
front passenger seat. If the
PAS SENGER AIR BAG OFF light comes on
and stays on o r flashes fo r abo ut 5 seconds while driving, under these
circumstances, make sure that:
• t he adult on the front passenger sea t is properly seated on the
center of the seat cushion with his or her back up against the backrest
and the backrest is not reclined=>
page 190, "Proper occupant
seating posit ions",
• the adult is not taking weig ht off the seat by holding on to the
passenger assist handle above the front passenger door or
supporting their weight on the armrest,
• the safety belt is be ing properly worn and that there is not a lot of
slack in the safety be lt webb ing,
• accessory seat covers or cushions or other th ings that may cause
an inco rre ct re ad ing o r impress ion on the weight-sens ing mat under the upholstery of the seat have bee
n removed from the front
p assenge r seat,
• a safety belt extender has not been left in the safety belt latch for
the front passenge r se at.
In add it io n to the
PASSENGER AIR BAG OFF light in the center of the
instrument panel, the message
PASSENGER AIR BAG OFF or
PASSENGER AIR BAG ON will br iefly appear in the instrument cluster
display . This is to inform the driver of the current front passenger
airbag status .•
Important safety instructions on

& WARNING
An a irbag system that is not fun ction ing properly cannot provide
supplemental protect ion in a frontal crash.
• If th e airbag indic ato r light comes on , it means th at there may
be someth ing wrong with the Advanc ed Airbag S ystem . It i s
poss ible that th e airbag will inflat e when it is not suppos ed to , or
will not inflate when it should.
• Hav e the a irb ag system inspected immediately by your autho

fore-and-aft and lateral directions, the brake pressure and the
steering angle are all measured.
The direction in which the driver wishes to travel is determined with
the aid of the steering angle and vehicle speed and is continually
compared with the actual behavior of the vehicle. If the two do not
match, for example, when the vehicle starts hydroplaning on a wet
road, ESP will automatically brake the appropriate whee l to correct
the problem.
The vehicle is then stabi lized by the forces acting on the whee l during
braking. If the vehicle is
oversteering (rear tends to skid out of the
turn), the brakes are main ly applied on the wheel that is on the
outs ide of the curve. In the case of a vehicle that is
understeering
(tendency to slide out of the curve), the brakes are applied as needed
on the wheel that is on the inside of the curve or additionally on the
other wheels. An acoustic s ignal indicates when ESP brake application
cuts in=> &.
The system operates across the entire speed range in combination
with the ABS system ~
page 256 . If the Anti -Lock Brake System
(ABS) ma lfunctions, the ESP wi ll be out of action as well.
Activating
When you turn on the engine, ESP will automatically be activated and
will perform a self-test. As soon as the test is comp leted, the system
is in normal operating mode .
Offroad mode
ESP should normally be operated in normal mode because this
ensures maximum vehicle stability. If necessary, you can activate the
ESP offroad mode by pressing the button=>
page 252, fig. 220 to
obtain maximum traction and braking ability when driving off paved
roads at low speeds. In ESP offroad mode, the ESP indicator light
=> page 16 illuminates and the message ESP Offroad Caution!
Limited driving stability
appears briefly in the disp lay.
The ESP offroad mode can be useful in the following exceptiona l situ
ations when slip or a highly effe ctive different ial loc king funct ion is
desirable. Examples:
Controls and equip ment Safety first Vehicle operation
•
when driving w ith tire chains,
• when driving in deep snow or on loose ground,
• when driving on uneven surfaces with the wheels severely
unloaded (articulation), and
• when rocking the vehicle loose a fter it has become stuck.
When the unusual situation is past, you should sh ift back to the
normal ESP operating mode by pushing the button again. The
message
ESP/ ASR on then appears briefly in the display.
Hill descent control
The hill descent control is switched on in ESP offroad mode. When
slowly descending steep gradients on loose ground or when the axles
are art iculated, hill descent control provides assistance by automati
cally applying the brakes to keep vehicle speed constant. The vehicle
is also rende red easier to steer by select ive distribution of braking
force. Hill descent control intervenes when:
• the accelerator pedal is not pressed,
• the vehicle is travelling less than 12 mph (20 km/h),
• a steep gradient is detected,
• wheel behavior indicates loose ground or conditions with poor
adhesion (e.g. also axle articulat ion).
Hill descent control operates both dr iving forward and in reverse.
Active hi ll descent control is deactivated by pressing the accelerator
pedal until the conditions for activation already listed are met aga in .
& WARNING
• The Electronic Stabilization Program is nevertheless subject to
the laws of physics . It is particularly important to pay attention to
this fact on wet and slippery roads. It is therefore important that
you always adapt your driving to the condition of the road and
traffic conditions. Do not allow the increased safety provided by
the Electronic Stabilization Program system to lull you into
accepting additional safety risks. ..

sudden in crease in e ngine speed as with a front -wheel drive
veh icle. Always drive at speeds which are suited to the road condi
tions - risk of crash .•
Energy management
Starting ability is optimized
E nergy ma nagement co ntr ols the distribution of elec
trical energy and thus optimizes the availa bility of elec
trical energy for s tarting the engine.
If a vehicle with a convention al ene rgy sys tem is not driven fo r a lo ng
pe riod of time, the battery is d ischarged by idling cu rr ent consumers
(e.g. immo bilizer) . In ce rtain c ircumstances it can result i n there
being insufficien t energy avai lab le to start the engine .
Inte llige nt ene rgy management in your ve hicl e han dles the dist ribu

Battery diagnosis
Battery d iagnosis continuously determ ines the state of the battery .

Dynamic energy management
While the vehicle is being dr iven, dynamic energy management
dis tributes the energy gene rated a ccording to the needs o f the in d i

Consider that t he power and life o f a battery are limited.
• If starting ab ility is threatened, yo u are informed by a warn ing

'-------------------------------------------------
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the remote key or power seat adjust
me nt, may not be available. The convenience functions will be avail
able again when you turn on the ignition and start the engine.
With the engine turned off
If you listen to the radio, for example, with the engine turned off or
use other MMI functions, the battery is being discharged.
If start ing capability is jeopardized due to energy consumption, the
following warning appears in the MMI display:
Please start engine, otherwise system will switch off in
3 minutes .
The warning indicates that the system will be turned off automati
cally after 3 minutes. If you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when the vehicle is being
driven, the battery can become 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 equilibr ium, consumers which
require especially large amounts of energy are temporarily cut back
or switched off. Heat ing systems in particular 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 temporarily cut
back or switched off. These systems will be available again as soon as
the energy balance has been restored .
You will also notice that engine idle speed has been increased
slightly. This is norma l and not a cause for concern. By increasing
engine idle speed the additional energy required is generated 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 following driver message:
i...-3 Low battery charge: battery will be charged while driving
This notification reminds you that the starting capability of the
engine may be limited. As soon as you start driving again, the battery
w ill be recharged and the notification will go out.
Driver notification appears and goes out again
If th is driver notification appears after the ignition is turned on or
whi le driving and it goes out again after a while, the battery has been
adequately recharged.
Driver notification appears and does not go out
again
If this driver notification appears after the ignition is turned on o r
wh ile driving and does not go out again, the battery's state of charge
is not in the optimal range. Starting ability is restricted. Have the
battery checked as soon as possible by an authorized Audi dealer or
qualified workshop. •
