Circular locator buttons on the rear seatback in­
dicate the lower anchorage locations on the rear
seat ing positions ¢fig. 160.
Lower anchorages
The lower anchorage attachment points are lo­
cated between the rear seatback and rear seat
cushion Qfig. 161 .
Lower anchorages secure the child restraint in
the seat without using the vehicle's safety belts.
Anchorages provide a secure and easy-to-use at­
tachment and minimize the possibility of improp­
er child restraint installation.
All child restraints manufactured after Septem­ ber 1, 2002, must have lower anchorage attach­
ments for the LATCH system.
Remember that the lower anchorage points are
only intended for installation and attachment of
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 .
_&. WARNING
Improper use of LATCH lower anchorages can
cause serious personal injury in an accident.
-Alway s carefully follow the child restraints
manufacturer's instructions for proper in­
stallation of the child restraint 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 restraints in this chapter
and WARNINGS ¢page 150, Child safety.

Installing a child restraint with LATCH

~ Depress the spring catches to release the an­
chorage hooks from the lower anchorages .
Remember: Use tether straps to he lp keep the
chi ld restraint firm ly in place.
A WARNING
Improper use of the LATCH system can in­
crease the risk of serious personal injury and
death in an acc ident.

Child safety
-Always make sure that you hear a click when
latching the seat in place. If you do not hear
a cl ick the seat is not secure and cou ld fly
forward and hit the inter ior of the vehicle,
or be ejected from the vehicle .
A WARNING

Improper installation of child restra ints w ill
i ncrease the risk of injury in an accident.
-Always follow the ch ild restraint system
manufacturer's instructions for proper in­
stallat io n of the chi ld restraint system a nd
proper use of tether straps as well as the

mat ion and WARNINGS abou t ch ild safety
and the installation of child restraint sys ­
tems
¢ page 150, Child safety.
Using tether straps on rearward-facing
child restraints
Currently, few rearward-facing child restraint
systems come w ith a tether . Please read and
heed the ch ild restraint system manufacturer's
instruct ions carefully to determ ine how to prop­
erly install the tethe r.
A WARNING
A child in a rearward-facing child safety seat
installed on the front passenger seat will be
seriously injured and can be ki lled if the front
airbag inflates - even with an Advanced Airbag
System.
- The inflating airbag will hit the child safety
seat or infant carrier with great force and
will smash the child safety seat and child against the backrest, center armrest, or
door .
- A tight tether or other strap on a rearward­
facing ch ild restraint attached to the front
passenger seat can put too much pressure
on the weight-mat in the seat and register a
heavier we ight in the Advanced Ai rbag Sys­
tem. The heavier weight registered can

Trailer towing 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.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle 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 with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
gi check to be sure that it conforms to all regula-......
~ tions . N ...... 0

LL 00
Trailer towing
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
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.
,8. WARNING
-If a tra iler has electr ical brakes please note
that these bra kes are not activated by the
factory-fitted control unit -risk of accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held sec ure ly in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer¢.&.
in Driving instructions on page 180.
Engine cooling system
Towing a trailer makes the engine work harder . It
is important that the cooling system's perform ­
ance is up to the additional load . Make sure that
the cool ing system has enough fluid. .,..

- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you cons ult an autho rized Aud i
dealer to have the cause of your concern properly d iagnosed. Keep in mind that the
accurate measurement of oil consump tion
requi res great care and may take some
time. An a uthorized Audi dea ler has instruc ­
tions about how to measure oil consump ­
tion accurately.
