• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat c an put too much p res su re
on the weight-sensing mat in the seat and reg ister 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 mu st be suppre ssed causing
serious or even fatal injury to the child .
• If, in exceptional circumstances , you must install a forward ­
f ac ing child restraint on the front passenger seat , always move the
seat into its rearmost position in the seat's fore and aft adjust ­
ment range , as far away from the airbag as possible . The ba ckrest
must be adju sted 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
• If the PASSENGER AIR BAG OFF light does not go out when an
adult is sitting on the front passenger seat after tak ing the steps
described above, make sure the adult i s properly seated and
restrained at one of the rear seat ing positions .
• Have the airbag system inspected by your Audi dealer before
transporting anyone on the front passenger seat .
[ i ] Tips
If the we ight -sens ing mat in the front passenger seat detects an
e m pty s eat, th e front airbag on the passenge r side wil l be tur ned
off , and the PASSENGER AIR BAG OFF li ght wil l stay on .•
Repair, care and disposal of the airbags
Parts of the airbag system are insta lled at many different places on
yo ur Audi. Ins tal li n g, r em oving, s ervicing o r rep airi ng a part in an area of the vehicle can damage a part of an airbag system and
p revent that sys tem from wo rking pr operly in a c ollisi on.
Th ere are some important th ings you have to know to ma ke sure
that the effectiveness of the system will not be impai red and that
discarded co mponents do no t cause i njury or po llute the enviro n­
ment.
& WARNING
Improper care , servicing and repair procedures can increase the
risk of personal injury and death by preventing an airbag from
deploying when needed or deploying an airbag unexpectedly :
• Never cover , obstruct , or change the steering wheel horn pad
or airbag cover or the instrument panel or modify them in any way.
• Never atta ch any objects su ch as cup holders or telephone
mountings to the surfaces covering the airbag units .
• For cleaning the horn pad or instrument panel , use only a soft ,
dry cloth or one moistened with plain water . Solvents or cleaners
could damage the airbag cover or change the stiffness or strength
of the material so that the airbag cannot deploy and protect prop ­
erly .
• Never repair , adjust, or change any parts of the airbag system .
• All work on the steering wheel , instrument panel , front seats or
electrical system (including the installation of audio equipment ,
cellular telephones and CB radios , etc .I must be performed by a
qualified technician who has the train ing and special equipment
necessary .
• For any work on the airbag system, we strongly recommend
that you see your author ized Audi dealer or qualified workshop .
• Never modify the front bumper or parts of the vehicle body .
• Always make sure that the side airbag can inflate without inter-
ference :

vidual components. It regulates consumption, so that more elec­
trical energy is not being used than is being genera ted 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.
• If starting ability is threatened, you are informed by a warning
~ page 277, "Driver notification in the instrument cluster
display". •
What you should know
The highest priority is given to maintaining starting capa ­
bility.
The battery is severely taxed in short -distance driving, in city traffic
and during the cold 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 e lectrical components are turned on. In this
instance energy is being consumed but none is being generated .
It is in precisely these situations that you wi ll notice energy manage ­
ment actively regulating the distribution of energy.
Vehicle stands for 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.
Be aware that when you unlock your vehicle, some of the conve ­
nience functions may not operate, such as the Convenience key, the
remote control or the power seat adjustment. The convenience
functions will be available again when you turn on the ignition and start the engine.
Controls and equip­ ment Safety first Vehicle operation
Intelligent technology
With the
engine turned off
If you listen to the radio, for examp le, 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 wi ll be turned off automati­
cal ly after 3 minutes. If you wish to continue using the functions,
you have to start the engine .
With the engine running
Although e lectrica l 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 equi librium , consumers
which require especia lly 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 wil l also notice that engine idle speed has been increased
s lightly . This is norma l and not a cause for concern . By increasing
engine idle speed the additiona l energy required is generated and
the battery is charged. •
Driver notification in the instrument cluster
display
If the battery's state of charge is not in the optimal range, this driver
notification appears in the instrument cluster display:
Low battery charge: battery will be charged while driving ~

It is not necessary to remove the battery from the lugga ge compart ­
men t, and it is als o not nec essary to disco nnect the cab les.
Fast charging the battery (charging rate above 14 .8
Volts )
For technical reasons do not use a battery charger that uses vo ltage
grea te r th an 14 .8 Vo lts to c harg e you r vehi cle 's bat te ry.
& WARNING
Charging a battery can be dangerou s.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery .
• Never charge a frozen battery . It may explode because of gas
trapped in the ice . Allow a frozen battery to thaw out first .
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery in a well ventilated area. Keep away from
open flame or electrical spark. Do not smoke . Hydrogen gas gener ­
ated by the battery is explosive.
• To reduce the dange r of explosion, never connect or disconnect
charger cables while the charger is operating.
• Fast charging a battery is dangerous and should only be
attempted by a competent technician with the proper equipment .
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid .
0 Note
Never use a fast charger as a booste r to start the engine . T his wil l
s eri ously damage se nsit iv e elect ron ic c ompo nents, suc h as control
units, re lays, radio, etc ., as wel l as the battery charger .•
