-Airbag system P'll:f _______________ _
& WARNING (continued)
• 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
Audi dealer.
& WARNING
If, in exceptional circumstances, you must install a forward-facing
child restraint on the front passenger's seat:
• 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. •
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-sensing mat, sensors, wiring, brackets, and more. The func
tion of the system in the front passenger seat is checked by the elec
tronic control unit when the ignition is on. The control unit monitors
the Advanced Airbag System and turns the airbag indicator light on
when a malfunction in the system components is detected. The
function of the airbag indicator light is described in greater detail below
. Because the front passenger seat contains important parts
of the Advanced Airbag System, you must take care to prevent it
from being damaged. Damage to the seat may prevent the
Advanced Airbag for the front passenger seat from doing its job in
a crash .
The front Advanced Airbag System consists of the
following:
• Crash sensors in the front of the vehicle that measure vehicle
acceleration/deceleration to provide information to the Advanced
Airbag System about the severity of the crash.
• An electronic control unit, with integrated crash sensors for front
and side impacts. The control unit "decides" whether to fire the
front airbags based on the information received from the crash
sensors. The control unit also "decides" whether the safety belt
pretensioners should be activated.
• An Advanced Airbag with gas generator for the driver inside the
steering wheel hub .
• An Advanced Airbag with gas generator inside the instrument
panel for the front passenger.
• A weight-sensing mat under the upholstery padding of the front
passenger seat cushion that measures the total weight on the seat.
The information registered is sent continuously to the electronic
control unit to regulate deployment of the front Advanced Airbag on
the passenger side.
• An airbag monitoring system and indicator light in the instru
ment cluster ~
page 226.
• The PASSENGER AIR BAG OFF light comes on and stays on in the
center of the instrument panel~
page 227, fig. 213 and tells you
when the front Advanced Airbag on the passenger side has been
turned off.
• A sensor below the safety belt latch for the front seat passenger
to measure the tension on the safety belt. The tension on the safety
belt and the weight registered by the weight -sensing mat help the
control unit "decide" whether the front airbag for the front ..

its size and age.
The
PASSENGER AIR BAG OFF l igh t sho uld NOT come on when the
ignition is on and an adult is sitt ing in a proper seating position on
the front passenge r seat . If the
PASSENGER AIR BAG OFF light
comes on a nd s tays o n or fl ashes for about 5 seco nds whi le d riving,
under these ci rcumstances, make sure that:
• the adult on the fron t pass enger sea t is pro perly s eate d on the

Important safety instructions on monitoring
the Advanced Airbag System
& WARNING
An airbag system that is not functioning properly cannot provide
supplemental protect ion in a frontal crash.
• If the airbag indicator light comes on , it means that there may
be something wrong with the Advanced Airbag System . It is
possible that the airbag will inflate when it is not supposed to, or
will not inflate when it should .
• Have the airbag system inspected immediately by your Audi
dealer .
& WARNING
• If the front airbag inflates , a child without 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 vehicle is equipped with an Advanced Airbag
System , make certain that all children , espec ially 12 years and
younger, always ride on the back seat properly restrained for their
age and size .
• Always install forward 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 be cause of exceptional cir cumstances and
the PASSENGER AIR BAG O FF light does not appear and stay on ,
immediately install the rear -facing child safety seat in a rear

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 conventional energy system is not driven for a
long period of time, the battery 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 engine .
Intelligent energy management in your vehicle handles the distribu
tion of electrical energy . Starting ability is markedly improved and
the life of the battery is extended.
Basical ly, energy management consists of
battery di agn osis, idling
current mana gement
and dynami c en ergy management .
Batter y diagn osis
Battery diagnosis continuously deter min es the state of the battery.
Sensors determine battery vo ltage, battery current and battery
temperature . This determines the cu rrent state of charge and the
power of the battery .
Idling c urrent man ag em en t
Idling current management reduces energy consumption while the
vehicle is standing. With the ign it ion switched off, it controls the
energy supply to the various electrical components. Data from
battery diagnos is is considered .
Depending on the battery's state of charge, individual consumers
are gradually turned off to prevent excessive discharge of the
battery and thus maintain starting capability.
Dynamic energ y managem ent
While the vehic le is being driven, dynamic energy management
distributes the energy gene rated acco rding to the needs of the indi -
Controls and equip
ment Safety first Vehicle operation
In
te llig ent tec hn olo gy
vidual components . It regulates consumption, so that more e lec
trical energy is not being used than is being ge nerated and ensures
an optimal state of charge for the battery.
[ i ] Tips
• But even energy management cannot negate the limits of
physics. Consider that the power and life of a battery are limited .
• I f starting ability is threatened, you are informed by a warning
=> page 270, "Drive r notifica tion i n the instrument cluster
display" .•
What you should know
The highes t pri ority is given to main tain ing starting capa
bility.
The battery is severe ly taxed in short-distance driving, in city traffic
and during the co ld time of year. Abundant electrical energy is
required, but only a little is generated. It is also critical if the engine
is not running and elect rica l components are turned on. In this
instance energy is being consumed but none is being generated .
I t is in precisely these situations that you will notice energy manage
ment active ly regula ting the distr ibut ion of energy.
Vehicle stands fo r an extended period
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period.
Take into considerat ion that when you un lock your veh icle, some
convenience functions, such as the remote key or power seat
adjustment, may not be availab le . T he conven ience functions will be
available again when you turn on the ignition and start the engine.
Vehicle care Do-it-yourself service Technical data

ll}J!I Intelligent technology
----'""------- ~---------------------------------------
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 starting 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 equilibrium , consumers
which require especially large amounts of energy are temporarily cut back or switched off. Heating 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 normal 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
d isplay
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:
'-' 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 will be recharged and the notification will go out.
Driver notification appears and goes out again
If this driver notification appears after the ignition is turned on or
while 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 or
while 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 at a dealership. •

Speed
The higher the speed, the more difficult it becomes for the driver to
control the rig. Do not drive at the maximum permissible speed. Reduce your speed even more if load, weather or wind conditions
are unfavorable -particularly when going downhi ll.
Reduce vehicle speed
im med ia tel y if the trailer shows the slightest
sign of swaying.
Do not try to s top the swayi ng by accelerating.
Observe speed limits. In some areas, speeds for vehicles towing
trai lers are lower than for regular vehicles .
Always apply brakes ear ly. When driving downhill, shift into a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes a lone can cause them to overheat and fail.
C ool ant t emp era tur e
The coolant temperature gauge=> page 12 must be observed care
fully. If the needle moves close to the upper end of the scale, reduce
speed immed iately and/or turn off the air conditioner.
If the coolant temperature warning light in the instrument cluster
starts flashing
- F- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat build-up.

Trailer towing tips
Important to know
Your vehicle handles differently when towing a trailer because of
the additional weight and different weight distribution. Safety, performance and economy will greatly depend on how carefully you
l
oad your trailer and operate your r ig.
Before you actually tow your trailer, practice turning, stopping and
backing up in an area away from traffic . Keep practicing unti l you
have become comp letely familiar with the way your vehicle-trai ler
combination behaves and responds.
Back ing up is difficult and requires practice. Backing up with a
trailer generally requires steering action opposite to that when backing up your vehic le without a tra iler.
Ma intain a greater distance between your veh ic le and the one in
front of you . You will need more room to stop. To compensate for
the trai ler, you w ill need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of the added load . Make su re you have
enough room to pass. After passing, allow plenty of room for your
trai ler befo re changing lanes again .
Avoid jerky starts, sharp turns or rapid lane changes.
[ i ] T ips
• Do not tow a trailer during the break -in period of your vehicle.
• I f you tow a trailer, your Audi may require more frequent main te
nance due to the extra load=>
page 372. •
Parking on a slope
Do n ot park on a slope with a trailer. If it cann ot be
avoi ded, do so only after d oing the followi ng:
When p arking :
-Apply the foot brake.
- Have someone p lace chocks under both the vehicle and
the trailer wheels. ._

Reduce your speed immediately and avoid any hard steer ing or
braking maneuvers. Stop as soon as possible and check the tires
and their pressures. Inflate the tire pressure to the proper pressure
as indicated on the vehicle's tire pressure label =>
page 321.
Driving on a significantly under-inflated tire causes the tire to over
heat and can lead to tire failure . Under- inflation also is l ikely to
impair the vehicle's handling and stopping ability .
