Child safety
-Always make sure the seat backrest to which
the child restraint is installed is in an up­
right position and securely latched into
place and cannot fold forward. Otherwise,
the seatback with the child safety seat at­
tached to it could fly forward in the event of
an accident or other emergency situation.

Deactivating the convertible locking
retractor
The convertible Locking retractor for child re­
straints will be deactivated automatically when
the belt is wound all the way bock into the re­
tractor .
~ Press the red button on the safety belt buckle.
Th@ belt tongue will pop out of the buckle.
~ Guide the safety belt all the way back into its
stowed position .
Always let the safety belt retract completely into
its stowed position . The safety belt can now be
used as an ordinary safety belt without the con­
vertible locking retractor for child restraints .
If the convertible locking retractor should be ac­
tivated inadvertently, the safety belt must be un­
fastened and guided completely back into its
stowed position to deactivate this feature. If the
convertible lock ing retractor is not deactivated,
the safety belt will gradually become tighter and
uncomfortable to wear.
A WARNING
-
Improperly installed child safety seats in­
crease the risk of serious personal injury and
death in a collision.
- Never unfasten the safety belt to deactivate
the convertible locking retractor for child re­ straints while the vehicle is moving . You

LATCH system (Lower
anchorages and tethers
for children)
' Child Restraint System anchors and how
are they related to child safety
To provide a simpler and more practicable way to
attach the child restraint on the vehicle seat, Federal regulations require special lower ancho­
rages in vehicles and devices on new child re­
straints to attach to the vehicle anchorages .
In the United States, the combination of the
tether anchorages and the lower anchorages is
now generally called the LATCH system for
"Lower Anchorages and Tethers for Children" . In
Canada, the terms "top tether" with "lower uni­
versal anchorages" (or "lower universal anchor­
age bars") are used to describe the system .
In other countries the term "ISOFIX" is used to
describe the lower anchorages .
Forward-facing child restraints manufactured af­
ter September 1, 1999, are required by U.S. fed­
eral regulations to comply with new child head
movement performance requirements . These
new performance requirements make a tether
necessary on most new child seats.
Installing a child restraint that requires a top
tether without one can seriously impair the per­
formance of the child restraint and its ab ility to
protect the child in a collision. Installing a child
restraint that requires a top tether without the
top tether may be a violation of state law.
Child restraint manufacturers offer LATCH lower
anchorages on their child seats with hook-on or ...

push-on connectors attached to adjustable
straps .
I n addition to the LATCH lower anchorages, these
child restraint systems usually require the use of
tether straps to h elp keep the child restraint
firm ly in place.
A WARNING
Improper installation of child restraints will
increase the risk of injury and death in a
crash.
- Always follow the instructions provided by the manufacturer of the child restra int you
intend to install in your veh icle.
- Never install a child restra int w ithout a
properly attached top tether strap if the
child restraint manufacturer's instruct ions
requ ire the top tether strap to be used .
- Improper use of child restra int LATCH lower
anchorage po ints can lead to injury in a colli ­
sion. The LATCH lower anchorage points are designed to withstand only those loads im­
posed by correc tly fit ted child res traints .
- Never mount two chi ld restraint systems on
one LATCH lower anchorage poin t.
- Never secure or attach any luggage or other
item to the LATCH lower anchorages .

Anchorages provide a secure and easy -to -use at ­
tachment and min imize the possibility of improp­
er child restraint installat ion.
All child restra ints manufactured after Septem­
ber 1 , 2002, must have lower anchorage attach ­
ments fo r the

Child safety
child restraints specifically certified for use with
LATCH lower anchorages. Child restraints that
are not equipped with the lower anchorage at­
tachments can still be installed in compliance
with the child restraint manufacturer's instruc­
tions on using vehicle safety belts .
A WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
- Always carefully follow the child restraints
manufacturer's instruct ions for proper in­
stallation of the child restra int and proper
use of the lower anchorages or safety belts
in your vehicle.
- Never secure or attach any luggage or other
items to the LATCH lower anchorages.
- Always read and heed the important infor­
mation about child restra ints in this chapter
and WARNINGS ~page 168, Child safety.
Guidance fixtures for lower anchorages
Special guidance fixtures increase the conven­
ience of the lower anchorages and are available
from your authorized Audi dealer .

tures per seat snaps into place.
Removing the guid ance fi xture s
.,. Remove the child restraint according the child
restraint manufacturer's instructions.
.,. Push down on the seat cushion so that the low ­
er anchorages are visible .
.,. Pull off the guida nee fixtures from the lower
anchorages .
.,. Always remove the g uidance fixtures and keep
them in a safe place when not in use.
You may find it easier to install child restra ints
equipped with hooks attached to str aps w ithout
the gu idance fixtures in place. If this is the case,
r emove the guidance f ixtures by pull ing them off
the anchorages . However, the gu idance fixtures
can help you to locate the LATCH anchorages.
A WARNING
Improper use of tether anchorages or lower
anchorages can cause ser ious personal injury
in a crash .
- Always carefully follow the ch ild restraint
manufacturer's instructions for proper i n­
stallation and use of child restraint systems .
- Never use the LATCH or tether anchorages
to attach safety belts or other kinds of occu­
pant restraints.
- Ch ild restraint tether attachments and low­
er attachments are only desig ned to secure
a child restraint that has been eq uipped to
use these an cho rages.

-Tether anchorages and lower anchorages
are designed to withstand only those loads
imposed by correctly fitted child restraints.
Under no circumstances can they be used
safely for adult or child safety belts or har­
nesses .
- Never mount more than one child restraint to a s ingle tether or to a lower anchorage
point. Attaching two ch ild restraints to a
s ingle anchorage point can ca use the an­
c horage to fa il and cause serious persona l
injury in a crash.
(D Note
- Remove the g uidance fixtures before fold­
i ng the rear seatback to prevent damaging
the seat cush ion.
- To attach the ch ild restraint securely, the
seat must be moved to the farthest rea r po­
s ition, the seat height se t to the lowest po ­
sition and the head restraint must be ad­
j u sted to the vertica l posit ion¢
page 61.
- If you leave the guidan ce fixt ures installed
for severa l days, they could leave a mark on
the upho lstery on t he seat c us h ion and
backrest in the area that the gu idance fix­
tures were installed. The upholstery would
also be permanently stretched around the
guidance fixtures. This applies especially to
leather seats.

(D Note
On vehicles with power adjustable rear seats*
some criteria must be observed when attach­
ing the child restraint using the
LA TCH sys ­
tem:
- To attach the chi ld restraint securely, the
seat must be moved to the farthest rear po­
sition, the seat height set to the lowest po­
sition and the head restraint must be ad­
justed to the vertical position
c'.:> page 61.
- If a ch ild safety seat is attached to one of
the rear seats , this seat must not be adjust­
ed using the power controls under any cir ­
cumstances . The
Entr y ass is ta n ce for th is
seat must also be deactivated in the MMI
r::> page 64. The child safety seat as wel l as
the rear seat can be damaged by the adjust­ ment process .
Tether anchors and tether straps
Fig. 18 4 Te ther a nch ors: recess flaps beh ind the rear sea t­
ba cks
The tether anchors for the two* /three rear seat­
ing positions are located in recesses in the rear
window shelf
r::> fig . 184 . Vehicles with two rear
seating positions* are equ ipped w ith two tether
anchors .
A tether is a straight or V-shaped strap that at­ taches the top part of a child restraint to special
anchorage points in the vehicle .
The purpose of the tether is to reduce the for­
ward movement of the child restraint in a crash, in order to help reduce the risk of head injury
184
that cou ld be caused by striking the vehicle inte­
r ior.
Forward facing child restra ints manufact ured af­
ter September 1, 1999, a re required by U.S. fed­
eral regu lations to comply with new child head
movement performance requirements . These
new performance requ irements make a tether
necessary on most new child safety seats.
A WARNING
Improper installation of child restraints wi ll
i ncrease the risk of injury and death in a
crash .
- Always follow the instructions provided by
the manufacturer of the ch ild restraint you
intend to install in your Audi .
- Improper use of chi ld restraint anchors (in­
cluding tether anchors) can lead to injury in
a co llision. The anchors are designed to
w ithsta nd only those loads imposed by cor­
rectly fitted ch ild restraints.
- Never mo unt two ch ild rest raint systems on
one LATC H lower anchor poin t.
- Never attach two child restraint systems to
one tether st rap or tethe r anchorage.
- Never attach a tether strap to a tie-down
hook in the luggage compa rtment .
- Never use child restra int tether anchorages
to secure safety belts or other kinds of occu­
pant restraints.
- Never secure or attach any luggage o r other
items to the LATCH lowe r anchorages or to
the te ther anchors.
- I f a tether or other strap is used to attach a
child restra int to the front passenge r seat,
make sure that it is not so tight, tha t it
causes the weight-sensing mat to meas ure
more weight than is actually on the seat.
- The heavier weight reg istered can make the

Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation.
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
(D Note
If you are going to tow a trailer, you must ac­
tivate the trai ler operation mode
¢ page 202, Operating instructions.
Technical requirements
Tr ailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your veh icle and trailer and must be mounted
securely on the vehicle's chassis at a
technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check w ith the t rail­
er h itch man ufact urer to make sure that you are
using the co rrect hitc h.
Do not u se a bumper hitch .
The hitch must be installed in such a way that it
does not interfere with the impact-absorbing
bumper system . No mod ificat ions should be
made to the vehicle exhaust and brake systems .
F rom t ime to t ime, check that a ll hitch mo unt ing
bolts rema in securely fastened.
When you are not tow ing a traile r, remove the
tra iler hitch ball mount. This prevents the hitch
from caus ing damage should your vehicle be
struck from behind
¢ ,&. .
202
Trailer b rakes
If your trailer is equipped with a braking system,
check to be sure that it co nforms to all regu la­
tions.
The tra iler hydrau lic brake system must not be
directly connected to the vehicle's hydrau lic
brake system .
Safety chains
Always use safety chains between your vehicle
and the tra iler.
Trailer light s
Trailer lights must meet all regulations. Be sure
to check with your Aud i dealer for correct wir ing,
switches and relays .
Mirror s
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors . It is important that you
always have clear vision to the rear.
A WARNING
Afte r remov ing the tra iler hitch, do not sto re
i t in you r vehicle. In case of s udden braking,
the hitch could fly fo rwa rd and injure you or
your passengers.

Maximum traile r weight
A tra iler for your vehicle is lim ited to a typical
class 1 or class 2 trailer.

Trailer load distribution
Be sure the load in the trailer is held securely in
p la ce to prevent it from sh ifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 204.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cool ing system's perform­
ance is up to the addit ional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
veh icle to the cold tire pressure listed under "Full
load " on the label located on the driver's side B­
pillar (vis ible when the door is open). Inflate
trailer tires to trailer and tire manufacturers'
specif ications.
Lights
Check to make sure both vehicle and trailer lights
are working proper ly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle.
Leave enough slack in the chains to permit turn­
in g corners . When you install safety cha ins, make
sure they wi ll not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separat ion
from the hitch.
Adjusting the Audi drive select
Make sure the vehicle is on a level surface before
hitching up the trailer and before adjusting the
tongue we ight. The vehicle must be in
auto or
comfort driving mode and not ra ised
¢ page 106, 9Q) .
Make sure that the vehicle is lowered. In Info­
tainment, select:
I CARI function button > lower
control button .
Trailer mode
If you must drive under poor road conditions, you
can raise the vehicle
after coupling the trailer or
after adjusting the tongue weight¢ page 108.
(D Note
-Changes in temperature or load can affect
the height of the vehicle.
- Always select auto or comfort mode. Other­
w ise, the tong ue load specified for your ve­
hicle will no longer be applicable .
Driving instructions
Driving with a trailer always requires extra care
and consideration.
T o obtain the best possible handling of veh icle
and trailer, p lease note the following:
.,. Do not tow a loaded trailer when your car itself
is not loaded.
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
.,. Do not drive at the maximum permissible
speed .
.,. Always apply brakes early.
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded tra iler with an empty car results
in a highly unstab le distribution of weight . If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possib le and permissib le, while
keeping the trailer as light as possible under the
cir cumstances . Whenever poss ible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing conside rations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the r ig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind .,._
