Activating the convertible locking retractor
Use the convertible locking retractor to secure a child
restraint.
Always heed the child safety seat manufacturer 's instruc­
tions when installing a child restraint in your vehicle. To
activate the convertible locking retractor:
- Place the child restraint on a seat, preferably on the rear
seat.
- Slowly pull the belt
all the way out.
- Route it around or through the child restraint belt path
=>& .
- Push the child safety seat down with your full weight to
get the safety belt really tight .
- Insert the belt tongue into the buckle for that seating
position.
- Gu ide the safety belt back into the retractor until the belt
lies flat and snug on the child safety seat.
Controls and equip­
ment Safety first Vehicle operation
- You should
hear a "clicking" noise as the belt winds back
into the inertia reel. Test the convertible locking retractor
by pul ling on the belt. You should no longer be able to
pull the belt out of the retractor. The convertible locking
retractor is now activated .
- Make sure that the red release button is facing away from
the child restraint so that it can be unbuckled quickly.
- Pull on the belt to make sure the safety belt is properly
tight and fastened so that the seat cannot move forward
or sideways more than one inch (2.5 cm).
& WARNING
Using the wrong child restraint or an improperly installed child
restraint can cause serious personal injury or death in a crash.
• Always make sure that the safety belt retractor is locked when
installing a child safety seat. An unlocked safety belt retractor
cannot hold the child safety seat in place during normal driving or
in a crash.
• Always buckle the child safety seat firmly in place even if a
child is not sitting in it. A loose child safety seat can fly around
during a sudden stop or in a crash.
• Always make sure the seat backrest to which the child restraint
is installed is in an upright position and securely latched into place
and cannot fold forward. Otherwise, the seat back with the child
safety seat attached to it could fly forward in the event of an acci­
dent or other emergency situation.
• Always read and heed all WARNINGS whenever using a child
restrained in a vehicle is being used=>
page 213. Special precau­
tions apply when installing a child safety seat on the front
passenger seat=>

& WARNING (continued )
• A tight tether or other strap on a rearward-facing child restraint
attached to the front passenger seat can put too much pressure
on the weight-mat in the seat and register a heavier weight in the
Advanced Airbag System. The heavier weight registered can make
the system work as though an adult were on the seat and deploy
the Advanced Airbag when it must be suppres sed causing serious
or even fatal injury to the child .
• If you must install a rearward facing child safety seat on the
front passenger seat because of exceptional c ircumstances and
the PASSENGER AIR BAG OFF light does not come on and stay on, immediately install the rearward-facing child safety seat in a rear
seating position and have the airbag system inspected by your

Notice about data recorded by
vehicle control modules
Your vehicle is not equipped with an Event Data Recorder (EDR),
installed by some manufacturers for the express purpose of
capturing data for retrieval after an accident or crash event . EDR's
are sometimes called "crash recorders".
Some state laws restrict the retrieval or downloading of data stored
by EDR's that were insta lled 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 electronic control modules for various vehicle systems such as, for example, eng ine function, emission control, as
well as for the airbags and safety belts.
These electronic control modules also record vehic le -related data
during norma l vehicle operation for diagnostic and repair purposes .
The recording capacity of the electronic cont rol modules is limited
to data (no sound is recorded) and only a small amount of data is
actually 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 vehic le 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 men t.
Electronic stabilization Program (ESP)
Gc,neral ;nformation
The ESP improves the veh icle s tabili ty.

swi tch
ESP is designed to help you maintain vehic le control in situations
where the car approaches the limits of "grip", especially when
accelerating and cornering. ESP reduces the risk of skidding and
improves stability under al l road conditions.

Normal surface stains can be cleaned using a commercially avail­
able foam cleaner . Spread the foam on the surface of the fabric with
a soft sponge and work it in gent ly . Do not saturate the fabric . Then
pat the foam dry us ing absorbent, dry cloths (e.g . microfiber c loth)
and vacuum it after it has dried completely .
Cleaning stains
Stains caused by beverages (e .g . coffee, fruit juice, etc.) can be
treated wi th a mild detergent so luti on. Apply the detergent so lution
with a sponge . In the case of stubborn stains, a detergent paste can
be applied di rectly to the stain and worked into the fabric . After ­
wards , use copious amounts of clean water to remove the
remaining detergent. App ly the water with a damp cloth or sponge
and pat the fabric dry with an absorbent, dry c lo th.
Stains from chocolate or makeup should have detergent paste
rubbed into them . Afterwards, remove the soap with water (damp
sponge) .
A lcohol can be used to treat stains from grease, oil, lipstick or a ball ­
point pen. Melted grease or dye must be patted o ff usi ng absorbent
material. It may be necessary to retreat the areas with detergent
paste and water .
In the case of genera l soiling of the upho lstery and cover material ,
we recommend hiring a specialist that has the equipment to clean
the seat covers and other fabric surfaces by shampooing and spray e xtrac tion .
& WARNING
Alway s read and heed all WARNINGS and the information
~ page 252 .
[ i ] Tips
Open Velcro fasteners on your clothing can damage the seat cover.
Please make sure that Velc ro fasteners a re c losed. •
Plastic parts and instrument panel
Always use a c lean cloth moistened in c lear water to clean these
areas. For persistent dir t use an Audi approved
solvent-free plas tic
cleaner/protectant.
& WARNING
Solvents can change the propertie s of some plastics and make it
harder fo r the airbag to deploy .
• Never clean the in strument panel or the surface of a irbag
module s with cleaning product s that contain sol vent s.
• Product s containing solvents will make the s urface of this part
porou s.
• Serious injuries can re sult if plastic parts come loo se when the
ai rbag i s deployed .
• Alway s read and heed all WARNINGS and other info rm ation
~ page 252.

Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of airbag deployment, the battery is discon­ nected from the vehicle electrical system for safety reasons=>
& in
"Repair, care and disposal of the airbags" on
page 202.
Disconnecting the battery terminals
Some vehicle functions (power window regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected again . To
prevent this, the battery should only be disconnected from the
vehic le electr ical system when absolute ly necessary for repairs .
Vehicles not driven for long periods
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period=>
page 241.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or power seat adjustment, may not be available. The convenience
functions will be available again when you turn on the ignition and start the engine .
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop . This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when traveling only short distances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=>
page 284 . A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i ] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being 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 compartment under
the floor. Before you check anything in the luggage
compartment,
read and heed all WARNINGS =:>& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury.
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
Always wear eye protection .
Battery acid contains sulfuric acid. Always wear
gloves and eye protection.
