child safety seat or improperly installing a
child restra int increases the r isk of serious
personal injury and death.
- All vehicle occupants and especially children
must a lways be restrained properly whenev­
er r iding in a vehicle.
- An unrest rained or imprope rly restrained
child can be injured or killed by being
thrown against the ins ide of the vehicle or
by being ejected from it during a s udden
maneuver or impact .

child is at much greater risk of injury or
death by being struck by an inflating air­ bag.
-Commercially available child safety seats
are required to comply with U.S . Federa l
Motor Vehicle Safety Standard (FMVSS) 213
(in Canada CMVSS 213).
-When buying a ch ild rest raint, se lect one

- Only use child restraint systems that fully
contact the flat portion of the seat cush­ ion. The child restrain t must no t tip or
lean to eithe r side. Audi does not recom­
mend using child safety seats that rest on
legs or tube-like frames. They do not pro­
vide adequate contact with the seat.

taining to the installation and use of child
safety seats and carefully follow the in­
structions provided by the manufacturer
of the seat you are using .
- Never allow ch ildren under 57 inches
(1.45 meters) to wear a normal safety belt.

neck a reas during sudden bra king maneu­
vers or ac ciden ts.
-Never let mo re than one child occupy a child
safety seat.
~ -Never let babies or older chi ld ren ride in a
~ vehicle while sitting on the lap of ano ther ......

jure each other in an accident .
- Never install rear-facing child safety seats
or infant carriers on the front passenger
seat . A child w ill be seriously injured and
can be killed when the passenger a irbag in­
flates -even with an Advanced Airbag Sys­
tem.
- The inflating airbag will h it the ch ild safety
seat o r infant ca rr ier with great force and

Child safety seats
Infant seats
Babies and infants up to about one year old and
20 lbs. or 9 kg need special rearward -facing
child restraints that support the back, neck and
head in a crash .
Fig. 2 4 0 Sche matic overview: rearward-facing infant seat,
properly installed on the rear seat
• When using the vehicle safety be lt to install a
child safety seat, you must first activate the
convertible locking retractor on the safety be lt
to prevent the child safety seat from moving
¢ page 259 or install the seat using the LA TCH
attachments.
• Push the child safety seat down with your full
weight to get the safety belt really tight so that
the seat cannot move forward or sideways
more than one inch (2.5 cm).
• Secure unused safety belts on the rear seat
¢page 254 .
Infants up to about one year (20 lbs. or 9 kg) are
best protected in spec ial infant carriers and child
safety seats des igned for their age group . Many
experts believe that infants and small children
should ride only in spec ial restraints in which the
chi ld faces the back of the veh icle. These infant
seats support the baby 's back, neck and head in a
crash
c!;> fig . 240.
The airbag on the passenger side makes the front
seat a potentially dangero us p lace for a child to
ride. The front seat is not the safest place for a
chi ld in a forward -facing child seat . It is a very
lL dangerous place for an infant or a larger child in t:0

A toddler or child is usually too large for an in­
fant restraint if it is more than one year old and
weighs more than 20 lbs. (9 kg).

Toddlers and children who are older than one
year up to about 4 years old and weigh more than
20 lbs (9 kg) up to 40 lbs. (18 kg) must always be
properly restrained in a child safety seat certified
for their size and weight

The airbag on the passenger side makes the front
seat a potentially dangerous place for a child to
ride. The front seat is not the safest place for a
child in a forward-facing child safety seat . It is a
very dangerous place for an infant or a larger
child in a rearward-facing seat .

install a forward or rearward-facing child re­
straint on the front passenger's seat in excep­
tional situations:

interfere with the airbag as it deploys and
seriously injure or even kill the child.
- Always carefully follow the manufacturer's
instructions provided with the child safety
seat or carrier.

that can increase the total weight registered by the weight-sensing mat and can cause in­
jury in a crash .

ufacturer for use on a front seat with a pas­
senger front and side a irbag .
- Never put the forward-facing child restraint

rearmost posit ion in the seat's fore and aft
adjustment range, as far away from the a ir­
bag as poss ible, before install ing the for­
ward-facing child restraint .

Care and cleaning
Care and cleaning
General information
Regular, proper care helps to maintain your vehi­
cle's value. It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from an authorized Audi dea ler or authorized
Audi Service Facility. Read and follow the instruc ­
tions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
- Always store clean ing and care products out
of reach of children to reduce the r isk of poi­
sonin g.
@ For the sake of the environment
- Preferab ly purchase environmenta lly-friend­
l y cleaning products.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve­
h icle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, r inse
off heavy deposits with
p lenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a microfiber cloth.
A lso, wash the underside of yo ur vehicle once
road sa lt stops being used for the season .
Pressure washers
When washing your veh icle w ith a pressure wash­
er , al ways fo llow the operating instructions pro­
vided with the press ure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at the
306
seals on the side windows, doors, lids or the sun­
roof* or at tires, rubber hoses, insulating materi ­
a l, sensors* or camera lenses* . Keep a distance of
at least 16 in (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use cone nozz les or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C) .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshie ld wipers are
off . Follow instruc ­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Only use car washes where the vehicle remains
stationary and the washing equipmen t moves
around the vehicle when washing and drying. Car
washes that move the vehicle t hrough the car
wash using a chain are not recommended .
Washing by hand
Clean the vehicl e starting from the top and work­
ing down using a soft sponge or cleaning brush.
Use solvent -free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi ­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply t he product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse t he ve hicle thoroughly with wate r. Then
clean using a neutral shampoo and a soft micro ­
fiber clot h.
R inse the vehicl e thoroughly again and let it air
dry. Remove any water residue using a chamois.
