that are seated in a child safety seat that is
appropriate for their weight and age and
that is secured with a safety belt.
In the event of a collision, vehicle occupants
that are not wearing safety belts could be
propelled through the vehicle interior and
collide with vehicle components, such as the
steering wheel, instrument panel, wind-
shield, or doors. In some situations, vehicle
occupants could also be ejected from the ve-
hicle. Vehicle occupants in the rear seats
who do not wear safety belts not only en-
danger themselves, but also other people in
the vehicle.
Only one person may be fastened with a
safety belt at a time. Never secure more
than one person, including children, with a
single safety belt.
Never allow children or infants to ride on an-
other person's lap and be belted into the
safety belt with them.
Insert the belt buckle only in the belt latch
belonging to the corresponding seat, so that
the protective function is not impaired.
To ensure the maximum protective function
of the safety belts, all vehicle passengers
must sit in the correct seating position
=> page 56.
Check the condition of your vehicle’s safety
belts regularly. If you find damage to the
belt webbing, the belt connections, the re-
tractor, or the buckle, have the damaged
safety belt replaced by an authorized Audi
dealer or authorized Audi Service Facility.
The safety belts must not be removed or
modified in any way. Do not attempt to re-
pair the safety belts yourself.
Safety belts that are strained during an acci-
dent, and thus stretched, must be replaced
by an authorized Audi dealer or authorized
Audi Service Facility.


Correct safety belt positioning

B4H-0751




Fig. 58 Safety belt positioning for pregnant women
:
B4L-1296
Fastened safety belts only offer optimal protec-
tion during an accident and reduce the risk of se-
rious injury or death when they are positioned
correctly. Furthermore, the correct safety belt
position holds the vehicle occupant in place so
that a deployed airbag can provide maximum
protection. Therefore, always fasten the safety
belt and make sure it is positioned correctly
> fig. 57.
To position the safety belt correctly, make sure
that:
— The lap portion of the safety belt lies across the
lap
—The shoulder portion of the safety belt lies over
the center of the shoulder
— The safety belt always rests flat and securely on
the body
For pregnant women, the safety belt must rest
evenly across the chest and as low and flat as
possible on the lap, so that no pressure is applied
to the lower abdomen. This should be done
throughout the entire pregnancy > fig. 58.

Sitting correctly and safely

front seats. Always transport children in suitable
child safety seats secured on the rear seats.
In exceptional circumstances: transporting
children in the front passenger's seat
If exceptional circumstances require the child
safety seat to be placed on the front passenger's
seat, then the front passenger's airbag must be
deactivated. Please note the important informa-
tion for this > page 67, Advanced airbag system.
If you must secure a forward-facing child safety
seat, move the front passenger's seat as far back
as possible so that it is as far as possible from the
front passenger's airbag. While doing this, make
sure the seat can be adjusted all the way.
Only switch to a larger child safety seat when
absolutely necessary
Switch to a larger child safety seat only when ab-
solutely necessary. Secure your child using a safe-
ty belt without a child safety seat only if all of the
following statements are true:
—The child is large enough to sit upright in the
seat
— The child is able to sit with his or her back rest-
ing completely on the seat backrest
—The child is able to sit with his or her knees
bent over the edge of the seat surface
—The child is able to sit with both of his or her
feet completely touching the floor in the foot-
well
—The lap portion of the safety belt lies flat and
securely over the hip area and never over the
stomach
— The shoulder portion of the safety belt lies flat
and securely over the center of the shoulder
and
the chest, and never under the arm, behind
the back, or over the neck or face.
—The child is able to maintain this seating posi-
tion throughout the entire trip
Read and follow the important information and
warnings regarding the correct use of safety belts
=> page 60.
@ Tips
— Child safety seats can also be secured to
seats with side airbags. In the event of an
accident, children can also be protected by
the side airbags if the child is correctly se-
cured in a suitable child safety seat that is
attached correctly.
— The lower LATCH anchors as well as the
safety belt may be required to correctly in-
stall some child safety seats. Using both at
the same time is permitted, provided that
the fastening systems or safety belts do not
impair those in an adjacent seating position.
—All child safety seats are constructed so that
they can be secured using the lap safety belt
in the vehicle.
— Child safety seats with a support base can
only be secured to the outer rear seats and
to the front passenger's seat.

Follow the safety precautions > page 69.
In the United States and Canada, child safety
seats can be secured without safety belts using
the LATCH system. LATCH stands for Lower An-
chors and Tethers for Children. In Canada, similar
systems are called UCRA, LUAS, or UAS.
The lower LATCH anchors in your vehicle are lo-
cated on the outer seats of the rear bench seat
between the seat surface and the backrest. These
seating locations each have two lower LATCH an-
chors that can be used to secure a LATCH child
safety seat. Marking points with a > fig. 65 sym-
bol are located on the covers for the lower LATCH
anchors. You can locate the LATCH anchors using
the marking points.

and Tires
General information
> Check your tires regularly for
damage, such as punctures,
cuts, cracks, and bulges. Remove
foreign objects from the tire
tread.
>If driving over curbs or similar
obstacles, drive slowly and ap-
proach the curb at an angle.
>Have faulty tires or rims re-
placed immediately.
>Protect your tires from oil and
grease.
>Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
>Lay tires flat when storing and
store them ina cool, dry location
with as little exposure to light as
possible.

A WARNING
—Never drive faster than the
maximum permitted speed for
your tires. This could cause the
tires to heat up too much. This
increases the risk of an acci-
dent because it can cause the
tire to burst.


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() Note
—Please note that summer and
winter tires are designed for
the conditions that are typical
in those seasons. Audi recom-
mends using winter tires dur-
ing the winter months. Low
temperatures significantly de-
crease the elasticity of summ-
er tires, which affects traction
and braking ability. If summer
tires are used in very cold tem-
peratures, cracks can form on
the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
—Burnished, polished or
chromed rims must not be
used in winter driving condi-
tions. The surface of the rims
does not have sufficient corro-
sion protection for this and
could be permanently dam-
aged by road salt or similar
substances.

Uniform Tire Quality Grading
is a tire information system devel-
oped by the United States Nation-
al Highway Traffic Safety Adminis-
tration (NHTSA) that is designed
to help buyers make relative com-
parisons among tires. The UTQG is
not a safety rating and not a guar-
antee that a tire will last for a
prescribed number of miles (kilo-
meters) or perform in a certain
way. It simply gives tire buyers
additional information to com-
bine with other considerations,
such as price, brand loyalty and
dealer recommendations. Under
UTQG, tires are graded by the tire
manufacturers in three areas:
treadwear, traction, and tempera-
ture resistance. The UTQG infor-
mation on the tires, molded into
the sidewalls.
U.S. DOT Tire Identification
Number (TIN)
This is the tire’s “serial number”.
It begins with the letters “DOT”
and indicates that the tire meets
all federal standards. The next
two numbers or letters indicate
the plant where it was manufac-
tured, and the last four numbers
represent the week and year of
manufacture. For example,
DOT... 2218...
means that the tire was produced
in the 22nd week of 2018. The

New tires or wheels
Audi recommends having all work
on tires or wheels performed by
an authorized Audi dealer or au-
thorized Audi Service Facility.
These facilities have the proper
knowledge and are equipped with
the required tools and replace-
ment parts.
>New tires do not yet have the
optimal gripping properties.
Drive carefully and at moderate
speeds for the first 350 miles
(500 km) with new tires.
> Only use tires with the same de-
sign, size (rolling circumfer-
ence), and as close to the same
tread pattern as possible on all
four wheels.
>Do not replace tires individually.
At least replace both tires on the
same axle at the same time.
> Audi recommends that you use
Audi Original Tires. If you would
like to use different tires, please
note that the tires may perform >

differently even if they are the
same size > (\.
>If you would like to equip your
vehicle with a tire and rim com-
bination that is different from
what was installed at the facto-
ry, consult with an authorized
Audi dealer or authorized Audi
Service Facility before making a
purchase > A.
Because the spare tire® is differ-
ent from the regular tires instal-
led on the vehicle (such as winter
tires or wide tires), only use the
spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re-
placed with a regular tire as soon
as possible.
All four wheels must be equipped
with tires that are the same brand
and have the same construction
and tread pattern so that the
drive system is not damaged by
different tire speeds. For this rea-
son, in case of emergency, only
use a Spare tire* that is the same
circumference as the regular tires.


Z\ WARNING
—Do not use steel rims that are
17 inches or larger. Otherwise,


damage to the vehicle and an
accident could result.
—Only use tire/rim combina-
tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
—For technical reasons, it is not
possible to use tires from oth-
er vehicles. In some cases, you
cannot even use tires from the
same vehicle model.
—Make sure that the tires you
select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif-
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
—Only use tires that are more
than six years old when abso-
lutely necessary and drive
carefully when doing so.
—Do not use run-flat tires on
your vehicle. Using them when
