(D Note
If you leave the c hild restraint with the
tether strap firmly installed for several
days, th is could leave a mark on the up­
holstery on the seat cushion and backrest
i n the area where the tether strap was in­
stalled. The upholstery would also be per­ manently stretched around the tether
strap. This app lies especia lly to leather
seats.
Using tether straps on rearward-facing
child restraints
Currently, few rear-facing child restraint sys­
tems come with a tether. Please read and
heed the child restraint system manufactur­
er's instructions carefully to determine how to
properly install the tether .
A WARNING ,.;; -
A child in a rearward-facing ch ild safety
seat installed on the fron t passenger seat
will be ser io usly injured and ca n be killed if
the front airbag inflates -even with an Ad ­
vanced Airbag System.
- The infla ting air bag will h it the ch ild
safety seat or i nfant carrier with great
force a nd will smas h the child safety seat
and child against the backrest, center
armrest, or door.
- A tight tether or other strap on a rear­
ward-facing child restraint attached to
the front passenger seat can put too
muc h pressure on the weight-mat in the
seat and register a heavier weight in the
Advanced A irbag System. The heavier
weight regis tered can make the system
wo rk as tho ugh an adult we re on the seat

The sensors can be displaced by impacts or
damage to the bumper, whee l housing and
underbody. This can affect the function of
the Audi pre sense system. Have your au­
thorized Audi dealer check to make sure
that the system is working properly .
@ Tips
-Certain Audi pre sense functions are not
available when ASR is sw itched off (sport
mode) or w hen driv ing in reverse.
- The Audi pre sense functions may not be
available if there is a malfunction in the
ESC system or the airbag control mod­
ule.
- The Audi pre sense front/plus f unctions
are not available if the re is a ma lfunction

Intelligent technology Notice about data
recorded by vehicle
control modules
Your vehicle is not equipped with an Event Da­
ta Recorder (EDR), installed by some manu­
facturers for the express purpose of capturing
data for retrieval after an accident or crash
event. EDR's are sometimes called "crash re­
corders".
Some state laws restrict the retr ieval or down­
loading of data stored by EDR's that were in­
stalled in a vehicle for the express purpose of
retrieving data after an accident or crash
event without the owner's consent.
Although your vehicle is not equipped with an
EDR, it is equipped with a number of electron­
ic control modules for various vehicle systems
such as, for examp le, engine function, emis­
sion control, as well as for the airbags and
safety belts.
These electronic control modules also record
vehicle-related data during norma l vehicle op­
eration for diagnostic and repair purposes.
The recording capacity of the electronic con­
trol modules is limited to data (no sound is re­
corded) and only a small amount of data is ac­
tually recorded over a very limited period of
time and stored when a system fault or other
condition is sensed by a control unit. Some of
the data then stored may relate to vehicle
speed, direction, braking as we ll as restraint
system use and performance in the event of a
crash or other condition. Stored data can only be read and downloaded with special equip­
ment.
Electronic Stabilization
Control (ESC)
Description
ESC helps to improve road holding and vehicle
dynamics to help reduce the probability of
skidding and loss of veh icle control. It works
only when the engine is running. ESC detects
Intelligent technology 199
certain difficult driving situations, including
when the vehicle is beginning to spin (yaw)
out of control and helps you to get the veh icle
back under control by se lectively braking the
wheels, and/or reducing engine power and
providing steering ass istance to help hold the
vehicle on the driver's intended course. The in­
dicator light
JjJ in the instrument cluster
blinks when ESC is taking action to help you
control the vehicle.
ESC has limitations .
It is important to remem­
ber that ESC cannot overcome the laws of
physics.
It will not always be able to help out
under all conditions you may come up against.
For example, ESC may not always be able to
help you master situations where there is a
sudden change in the coefficient of friction of
the road surface. When there is a section of dry road that is suddenly covered with water,
slush or snow, ESC cannot perform the same
way it would on the dry surface. If the vehicle
hydroplanes (rides on a cushion of water in­
stead of the road surface), ESC will not be
able to help you steer the vehicle because con­
tact with the pavement has been interrupted
and the vehicle cannot be braked or steered .
During fast cornering, particularly on winding
roads, ESC cannot always deal as effectively
with difficult driving situations than at lower
speeds. When towing a trailer, ESC is not able
to help you regain control as it would if you
were not tow ing a trailer.
A lways adjust your speed and driving style to
road, traffic and weather conditions. ESC can­
not override the vehicle's physical limits, in­
crease the available traction, or keep a vehicle
on the road if road departure is a result of
driver inattention. Instead, ESC improves the
poss ibility of keeping the vehicle under con­
trol and on the road dur ing extreme maneu­
vers by using the driver's steering inputs to
help keep the vehicle going in the intended di­
rection. If you are traveling at a speed that
causes you to run off the road before ESC can
provide any assistance, you may not experi­
ence the benefits of ESC.

long. This can seriously affect the effi­
ciency of the brakes as well as yo ur
safety. This could result in an acc ident.
0 Note
Brake f luid will damage the paint of your
vehicle.
@ For the sake of the environment
Because of the problem of proper d isposa l
of brake fl uid as we ll as the special tools
req uired and the necessa ry expert ise, we
recommend that you have the brake fluid
changed by your author ized Audi dealer.
Battery
General information
Under normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance . With
high outside temperatures or
long dai ly dr ives we recommend that you have
the electro lyte level checked by a service fa­
cility. T he electrolyte level shou ld also be
checked each time the battery is charged
-:;, page 245.
Have the battery checked when you take your
ve hicle in for service. You are well adv ised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢
& in Re­
pair, care and disposal of the airbags on
page 167.
Disconnect ing the battery terminals
Some vehicle functions (power w indow regu­
lators, for example) are lost if the battery ter­
minals a re d isconnected. These functions have
to be relearned after the battery terminals a re
connected again . To prevent this, the battery
should only be d isconnected from the vehicle
e lec trica l system whe n absolu tely ne cessa ry
f or repairs.
Checkin g and fillin g 243
Vehicles not driven for long periods
If you do no t drive your vehicle over a period
of seve ra l days o r weeks, e lectr ica l compo ­
nents are g radually cut back or switched off .
This reduces energy consumption and main­
ta ins starting capability over a longer period
¢
page 204. Some of the convenience func­
tions may not operate, such as the inter ior
l igh ts or the power seat adjus tment. The con­
venience functions will be ava ilab le aga in
whe n you swi tch on the ignition and sta rt the
engine.
Winter operation
During the winte r months, battery capacity
tends to dec rease as temperatures drop. This
i s because more power is a lso consumed wh ile
s ta rt ing, and the headlight s, rea r window de­
fogger, e tc., are used more ofte n.
Avoid unnecessary powe r consumpt ion, par­
ticu larly in city traffic o r when traveling only
sho rt distances. Let yo ur au thoriz ed Aud i
de aler check the cap acity of the vehicle b at­
tery before winter sets in~ page 245. A well
charged bat tery will not on ly prevent starting
problems w hen the weather is cold, but w ill
a lso last longer.
{!) Tips
If yo ur vehicle is left s tandin g for seve ral
weeks at extreme ly low tem peratures, the
vehicle battery sho uld be removed and
stored w here it w ill not freeze . T his will
prevent it from be ing damaged and having
to be replaced.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart ­
ment under the floor. Before you check any­
th ing in the luggage compartment,
read and
heed all WARNINGS
¢ .&_ .
Always heed the safety warnings , when work­
ing on the vehicle battery or the vehicle e lec­
trical system to prevent injury. •
