& WARNING
Improper installation of child restraints will increa se the r is k of
injury and death in a crash .
• Improper use of child restraint anchors (tether anchors) could
lead to injury in a colli sion. The anchor s are designed to withstand
only tho se load s impo sed by correctly fitted child restraints .
• Never mount two child restraint systems on one LATCH lower
anchor point .
• Never attach two child restraint sy stems to one tether strap or
tether anchorage .
• Always follow the instructions provided by the manufacturer of
the child restraint you intend to install in your Audi .
• Never use child restraint tether anchorages to secure safety
belts or other kinds of occupant restraint s.
• Never atta ch a tether strap to a tie -down hook in the luggage
compartment.
• Never secure or attach any luggage or other items to the LATCH
lower anchorages or to the tether anchors .
• If a tether or other strap is used to attach a child restraint to the
front passenger seat , make sure that it is not so tight , that it
c auses the weight -sensing mat to measure 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 serious or even fatal 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 -.,.

consider if children, anima ls or other factors m ight prove to be
partic ularly hard on the leather.
By contrast, leather types that are covered by a colored finish layer
are more durable. This has a positive effect on the leather 's resis ­
tance to wear and soiling in da ily use. On the ot her hand, the typica l
characteristics of natural leather are barely or not apparent.
However, this does not mean that the leather itself is of inferior
quality .
Care and h andling
Because of the exclusive nature of the types of leather that Audi
uses and their unique properties (such as sensitivity to oils, grease,
soiling, etc.l, you will need to be somewhat careful with these
lea thers, and a cer tain type of care is requ ired . For example, dark
clothing materials can discolor leather seats (especial ly if such
clothing is damp and was not dyed correctly). Dust and dirt par ticles
in pores , folds, and seams can have an abrasive effect and can
damage the leather surface as well as weaken seams .
The leather shou ld be c leaned regularly as needed . After having
been used for a relatively long time , your leather seats will acquire
a rich aged finish . This is a characteristic of natural leather and a
sign of true qua lity.
I n order to maintain the value of this natural p roduc t over the life of
your vehic le, you should fo llow the recommendations below :
0 Note
• To keep your leather from b leaching out, do not allow it to be
exposed to bright sun light for long per iods of time . If you have to
leave the vehicle parked outside for long periods, cover the leather
to protect it from direct exposure to sunlight.
• Sharp ob jects on c lothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or sc rape marks on the
surface of t he leather.
[ i ] Tip s
• After each time you clean the leathe r and at regular intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather . This creme wil l nour ish and moisturize the
leather, helping it to breathe and stay supple . It a lso helps to build
up a protect ive coating on the sur face .
• Clean the leather every 2 -3 months, and c lean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc . as soon as possible .
• Preserve the co lor of the leather as needed by using a special
colored leather care creme to touch up areas of uneven co lor. •

& WARNING
Overload ing a vehicle can cause loss of vehicle control , a crash or

will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control . .,_

0 Note
Driving without valve stem caps can cause damage to the tire
valves. To prevent this, always make sure that factory installed valve
stem caps on all wheels are securely mounted on the valve .
W For the sake of the environment
Underinflated tires will also increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any tire can carry . A vehicle that is overloaded will not handle well
and is more difficult to stop. Overloading can not only lead to loss
of vehicle control, but can also damage important parts of the
vehicle and can lead to sudden tire failure, including a blowout and
sudden deflation that can cause the vehicle to crash.
Your safety and that of your passengers also depends on making
sure that load limits are not exceeded. Vehicle load includes every­
body and everything in and on the vehicle. These load limits are
technically referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"l.
The "GVWR" includes the weight of the basic vehicle, all factory
installed accessories, a full tank of fuel, oil , coolant and other fluids
plus maximum load. The maximum load includes the number of
passengers that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating position and the total weight of any luggage in
the vehicle. If you tow a trailer, the weight of the trailer hitch and the
tongue weight of the loaded trailer must be included as part of the
vehicle load.
The
Gross Axle Weight Rating ("GAWR"l is the maximum load that
can be applied at each of the vehicle's two axles. The
Gross Vehicle Weight Rating and the Gross Axle Weight Rating
are listed on the safety compliance sticker label located either on
the driver's side 8-pillar or on the inside of the fuel filler flap. Your
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating capacity of 5. Vehicles with power individual rear seats*
have 4 seating positions, 2 in the front and 2 in the rear for total
seating capacity of 4. Each seating position has a safety belt
~ page 211, "Safety belts".
The fact that there is an upper limit to your vehicle's Gross Vehicle
Weight Rating means that the total weight of whatever is being
carried in the vehicle (including the weight of a trailer hitch and the
tongue weight of the loaded trailer) is limited. The more passengers
in the vehicle or passengers who are heavier than the standard
weights assumed mean that less weight can be carried as luggage.
The tire pressure label on your Audi also lists the maximum
combined weight of all of the occupants and luggage or other cargo
that the vehicle can carry. For the location of the label
~ page 330,
fig. 274.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance.
• Tires on a vehicle that has been overloaded can fail suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating. •
