Installing the guidance fixtures
- Push down on the seat cushion so that the lower anchor ­
ages are visible.
- Hold the guidance fixture with the part number facing downward and push it in the direction of the arrow onto
the
anchorage => page 259, fig. 248.
- Make sure that each of the two guidance fixtures per seat snaps into place.
Removing the guidance fixtures
- Remove the child restraint according the child restraint manufacturer's instructions.
- Push down on the seat cushion so that the lower anchor ­
ages are visible.
- Pull off the guidance fixtures from the lower anchorages.
-Always remove the guidance fixtures and keep them in a
safe place when not in use.
You may find it easier to install child restraints equipped with hooks
attached to straps without the guidance fixtures in place . If this is
the case, remove the guidance fixtures by pulling them off the
anchorages. However, the guidance fixtures can help you to locate
the
LATCH anchorages.
& WARNING
Improper use of tether anchorages or lower anchorages can cause
serious personal injury in a crash.
• Always carefully follow the child restraint manufacturer's
instructions for proper installation and use of child restraint
systems.
& WARNING (continued)
• Never use the LATCH or tether anchorages to attach safety
belts or other kinds of occupant restraints.
• Child restraint tether attachments and lower attachments are
only designed to secure a child restraint that has been equipped
to use these anchorages.
• Tether anchorages and lower anchorages are designed to with­
stand only those loads imposed by correctly fitted child restraints.
Under no circumstances can they be used safely for adult or child
safety belts or harnesses.
• Never mount more than one child restraint to a single tether or
to a lower anchorage point. Attaching two child restraints to a
single anchorage point can cause the anchorage to fail and cause
serious personal injury in a crash.
0 Note
• Remove the guidance fixtures before folding the rear seatback to
prevent damaging the seat cushion.
• If you leave the guidance fixtures installed for several days, they
could leave a mark on the upholstery on the seat cushion and back­
rest in the area that the guidance fixtures were installed. The uphol ­
stery would also be permanently stretched around the guidance
fixtures . This applies especially to leather seats.
[ i] Tips
• Always remove the guidance fixtures when not in use .
• Please keep the guidance fixtures in a safe place with the vehicle
when not in use. •

0 Note
On vehicles with power individual rear seats* some criteria must be
observed when attaching the child restraint using the
LATCH
system:
• To attach the child restraint securely, the seat must be moved to
the farthest rear position, the seat height set to the lowest position and the head restraint must be adjusted to the vertical position
=> page 97.
• If a child safety seat is attached to one of the rear seats, this seat
must not be adjusted using the power controls under any circum­
stances. The easy entry function for this seat must also be deacti ­
vated in the
MMI => page 100 . The child safety seat as well as the
rear seat can be damaged by the adjustment process .•
Mounting and releasing the anchorage hook
If you use a child restraint system with hooks or other
latches attached to adjustable straps.
Mounting
- Press the anchorage hook with the spring catch release
onto the lower anchorage so that the anchorage hook
locks into place .
- Pull on the anchorage hook to make sure that it has
securely engaged the lower anchorage.
- Tighten the strap following the child restraint manufac­
turer's instructions.
Releasing
-Loosen the tension on the strap following the child
restraint manufacturer's instructions .
- Depress the spring catch on the hook. -
Hold the spring catch in depressed position.
-Move the hook in the direction of the vehicle floor so that
there is enough space to release the anchorage hook
from the lower anchorage.
& WARNING
• Improper installation of child restraints will increase the risk of
injuries in a crash.
• Always refer to the child restraints manufacturer's instructions
for proper installation of the child restraint and proper use of the
lower anchorages or safety belts in your vehicle.

vidual components . It regulates consumption, so that more elec­
t rical energy is not be ing used than is be ing genera ted and ensures
an optimal state of charge for the battery .
[ i ] Tip s
• 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 275, "Driver notification in the instrument cluster
display" .•
What you should know
The highest priority is given to maintaining starting capa ­
bility.
T he battery is severely taxed in short -distance driving, in city traffic
and during t he co ld time of year . Abundant e lectrica l energy is
required, but on ly 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 .
I t is in precisely these situations that you wi ll notice energy manage ­
ment active ly regulating the d istr ibut ion of energy.
Vehicl e stands for an extended period
If you do not drive your vehicle over a per iod of several days or
weeks, electrica l components are gradually cut back or switched off.
This reduces energy consu mpt ion and maintains starting capability
over a longer period .
Be aware t hat when you unlock you r ve hicle, some o f the conve ­
nience functions may not operate, such as the Advanced Key, the
remote contro l or t he power seat adjustment. T he convenience
functions will be available again when you turn on the ignition and start the engine .
Controls and equip­
ment Safety first Vehicle operation With th
e engin e turned off
If you listen to the radio, for examp le, with t he engine tu rned off or
use other MMI functions, the battery is being discharged.
I f starting capabi lity is jeopardized due to energy consumption, the
f o llow ing warn ing appears in t he MMI display:
Ple ase start engine , other wise sy stem will s witch off in 3
minute s.
The warning indicates that the system wi ll be turned off au tomat i­
ca lly 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 vehic le is being
driven, the battery can become discharged. This happens mostly
when little energy is being generated and a great deal co nsumed
and the battery's state of charge is not optimal.
To br ing the ene rgy balance bac k into equi librium , cons umers
which require especially large amounts of energy are temporar ily
cu t back or switched off . Heating systems in part icu lar require a
great deal of energy. If you notice, for example, that the heated
seats* o r the heated rear w indow are not heating, they have been
temporari ly cut back or switc hed off. These systems wil l be avai lable
again as soon as the energy balance has been restored.
You wil l also notice t hat engi ne idle speed has been increase d
s lightly . This is norma l and not a cause for concern . By increasing
engine idle speed the addi tiona l energy required is ge nerated a nd
the battery is charged. •

& WARNING
Always read and heed all WARNINGS and other informat ion
=> page 288 . •
Fabrics and fabric coverings
Fabrics and fabric coverings (e.g . seats, door trim pane ls, etc.)
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
the steam tends to push the d irt deeper into the fa bric and lock it
there.
Normal cle aning
Genera lly, we recommend using a soft sponge or a lint -free
m icrofiber c loth to the clean fabric . Brushes should only be used for
carpets and floor mats, since other fabric surfaces could be harmed
b y b rushes.
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 . T hen
pat the foam dry using absorbent, dry cloths (e.g. microfiber cloth)
and vacuum it a fter it has dr ied completely .
Cleaning stains
Stains caused by beverages (e.g. coffee, fruit juice, etc.l 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, animals or other factors might prove to be
particularly 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 daily use. On the other 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 handling
Because of the exclusive nature of the types of leather that Audi
uses and their unique properties (such as sensitivity to oi ls, grease,
soiling,
etc.I, you will need to be somewhat careful with these
leathers, and a certain type of care is required. For example, dark
clothing materials can discolor leather seats (especially if such
clothing is damp and was not dyed correctly). Dust and dirt particles
in pores, folds, and seams can have an abrasive effect and can
damage the leather surface as we ll 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 quality.
In order to maintain the value of this natura l product over the life of
your vehicle, you should follow the recommendations below :
0 Note
• To keep your leather from bleaching out, do not allow it to be
exposed to bright sunlight for long periods 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 objects on clothing, such as zippers, rivets or sharp pieces
on belts can leave permanent scratches or scrape marks on the
surface of the leather.
[ i] Tips
• After each time you clean the leather and at regular intervals, use
a leather preservative creme that contains UV -blockers and that
works into the leather . This creme wil l nourish and moisturize the
leather, helping it to breathe and stay supple . It also helps to build
up a protective coating on the surface .
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc . as soon as possible .
• Preserve the color of the leather as needed by using a special
colored leather care creme to touch up areas of uneven color. •

Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
- Clean soiled areas with a slightly moistened cotton or
woolen cloth.
More stubborn dirt
- More stubborn dirt can be removed using a cloth satu­
rated with a mild soap solution (2 tablespoons mild
liquid soap) .
- Never allow the soap solution to saturate the leather, and
make certain that no water soaks into the seams .
- Wipe off the soap solution with a soft, dry cloth.

crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or
reinforced by ply cords and that is shaped to fit the rim.
Bead separation
means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their
"previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage.
•
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted.
Curb weight
means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
