& WARNING
A child in a rearward -facing child 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 seat or infant carrier with
great force and will smash the child seat and child against the
backrest , center arm rest, door or roof .
• Always install rear-facing child seats on the rear seat.
• If you must install a rearward facing child 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 seat in a rear seating posi­
tion and have the airbag system inspected by your Audi dealer.
• Forward -facing child seats installed on the front passenger's
seat may interfere with the deployment of the airbag and cause
serious personal injury to the child .

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 ~

Care of interior
MMI display
- Clean th e MMI display with a soft c lean cloth and an LCD
cl eane r.
The MM I disp lay can be cleaned with a professional ly available "LCD
cleaner". The cloth should be s lightly dampened with the c leaning
fluid to clean the display.
0 Note
T o avoid scra tching the MMI display, you should never c lean it dry .•
MMI terminal
- First clean the MMI terminal with a brush to remove dust
from the housing.
- T hen wipe the MMI terminal wit h a clea n, soft, s lig htly
damp cloth .
The MMI terminal shou ld be c leaned with a brush first so that no
dirt is trapped between the buttons and the housing. We recom­
mend giving the MM I terminal a final wipe with a c loth moistened
with water and dish washing dete rgent.
0 Note
To prevent damage, make sure that no flu id ever gets into the M MI
terminal. •
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
a lum inum surfaces . C hro me care products an d alka line cleaners
wi ll attack aluminum surfaces and can damage them over time.
& WARNING
Always read and heed all WARNINGS and other information
~ page 290 .•
Fabrics and fabric coverings
Fabrics and fabric coverings (e.g . seats, door trim panels, etc.l
shou ld be c leaned at regular intervals with a vacuum cleaner . This
re moves surface dirt partic les which could become embedded in
the fabric through use. Steam cleaners shou ld not be used, because
t he steam tends to push the d irt deeper into the fabric and lock it
there.
Normal cl eaning
Genera lly, we recommend using a soft sponge or a lint -free
microf iber c loth to the clean fabric . Brushes should on ly be used for
carpets and floor mats, since other fabric surfaces could be harmed
by brushes.
Norma l surface stains can be cleaned using a commercially avail ­
able foam cleaner. Spread the foam on the surface of the fabric with
a soft sponge and work it in gent ly. Do not saturate the fabric . Then
pat the foam dry using absorbent, d ry cloths (e.g. microfiber cloth)
and vacuum it a fter it has dried completely .
Cleaning stains
Stains caused by beverages (e.g. coffee, fruit juice, etc.) can be
treated with a mild detergent so lution . Apply the detergent so lution
with a sponge. In the case of stubborn stains, a detergent paste can be applied direct ly to the stain and worked into the fabric. After -.,.
Vehicle care I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• If the spare tire is different from the tires that you have mounted
o n your vehi cle (for e xample winter tires or wide profile tires), then
use the spare tire for a short period of time on ly and drive with extra
care . Replace the f lat tire with the tire matching the others on your
vehicle as soon as possible.
• If you should put different wheels and tires on your vehicle (e.g.
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system* .
Otherwise the system will register a ma lfunction and a fault
message will be displayed . For more information, contact your Audi
dea ler.
0 Note
• When installing new tires, be careful not to damage the valves or
tire pressure monitoring system* sensors.
• Never drive without the va lve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
c£> For the sake of the environment
Dispose of old tires in accordance with the loca l requirements. •
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Qua lity grades can be found where applicable on the tire side wal l
between tread shoulder and maximum section width
=> page 338,
fig. 278.
For e xample: Tread wear 200 , Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require­
ments in addit ion to these grades.
Tread w ea r
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under contro lled conditions on a specified
government test course.
For example, a tire graded 150 wou ld wear one and one half (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upo n the actua l condi­
tions of their use, however, and may depart significantly from the
n orm due to variations in d riving habi ts, service practices and differ­
ences in road characteristics and climate.
Tra ction
The traction grades, from highest to lowest, are AA, A, Band C.
Those grades represent the tire's ability to stop on wet pavement as
measured under contro lled conditions on specified government
t est surfaces of asphalt and concrete . A tire marked C may have
poor traction performance => & .
Temperature
The temperature grades are A (the highest), 8, and C, representing
the tire's resistance to the generation o f heat and its abi lity to dissi ­
pate heat when tested under control led conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the mater ial of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>&.
T he grade C corresponds to a leve l of performance which a ll
passenger car tires must meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades Band A represent higher levels of
p er formance on the la b ora tory test whee l than t he mi nimum
required by law.
