the children could start the engine or oper­ate electrical equipment such as power win­
dows .
- For safety reasons, always park the vehicle
with the selector lever in the P position.
Otherwise, there is the risk that the vehicle
could roll.
- After the engine has been switched off, the
radiator fan can continue to run for up to 10
minutes -even with the ignition switched
off.
It can also switch on again after some
time if the coolant temperature rises as a
result of heat build up or if the engine com­
partment is heated by sunlight and the en­
gine is hot.
(D Note
- If the engine has been under heavy load for
an extended period of time, heat builds up
in the engine compartment after the engine
is switched off -there is a risk of damaging
the engine . For this reason, let the engine
run for at idle for approximately two mi­
nutes before shutting it off.

Electronic stabilization
control (ESC)
Description
The E lectronic Stabilization Contro l (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti ­
cal s ituations such as the vehicle oversteering
and understeering or the wheels a re spinning.
The vehicle is stabilized by applying the brakes or
reducing engine torque. Once the ESC is activat­
ed, the indicator light
DJ blinks in the instru­
ment cluster.
The fol low ing systems a re integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
i ng. The vehicle can still be steered even during
hard braking . Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal ind icates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the driver
presses the brake pedal quickly in emergency s it­
uations. You must press and hold the brake pedal
unti l the dangerous sit uation is ove r. In vehicles
with adaptive cruise control *, the brake assist
system is more sensit ive if the distance detected
to the vehicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up inclines.
Intelligent Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other drive wheel
or whee ls if the vehicle is equipped with all wheel
drive*). This function is not available at higher
speeds.
In extreme cases, EDL automatically switches off
to keep the brake on the braked wheel from over ­
heating. The vehicle is still working correct ly. EDL
will switch on again automatically when condi­
tions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
Selective wheel torque control
Selective wheel torque control is used when dr iv­
i ng on curves. The front wheel on the inside of
the curve o r both wheels on the inside of the
curve are braked selectively as needed . This al­
lows more precise driving in curves .
Automatic post-collision braking system
The "Automat ic post -collision braking system"
can help to reduce the ris k of sliding and of other
collisions after an accident. If the airbag control
module detects a collision above a certain vehicle
speed, the vehicle is braked by the ESC.
T he vehicle does not brake automatically if:
- the driver presses the accelerator pedal, or
- the braking force generated by the pressed
brake pedal is greater than the brak ing force
that would be initiated by the system, or
- the ESC, the brake system or the vehicle electr i­
cal system are not funct ion ing .
A WARNING
-The ESC and its integrated systems cannot
overcome the limits posed by natural phys i­
cal laws. This is especially important on slip­
pery or wet roads .
If the systems begin act­
ing to stabilize your vehicle, you should im-
mediately a lter your speed to match the ..,.

With the engine switched off
The battery will dra in if you use functions s uch as
listening to the radio while the engine is switched
off.
The vehicle 's ability to start may be impaired by
the energy use, a message w ill appear in the In­
fotainment system disp lay.
The message ind icates that the system will
switch off automatically soon.
If you would like
to continue using the functions, you must start
the eng ine.
With the engine running
Although electrical energy is generated wh ile
driving, the batte ry can drain. This can happen
when little energy is gene rated, and much is used
and the charge level of the battery is not optima l.
To restore the balance of energy, components
that require large amounts of energy are tempo­
r ar ily sca led back or switched off. Heating sys­
tems in particular require a great deal of energy.
If you notice, for example, that the seat heating*
or rear window defroster is not working, then it
has been temporari ly reduced or switched off .
These systems are avai lab le aga in as soon as the
energy balance has been restored.
In addition, you may notice that the idle speed
has slightly increased . That is normal and no
cause for concern. Due to the increased idling
speed, the add itional required energy w ill be gen­
erated and the battery will be charged .

Gasoline additives
A ma jor concern among many auto manufactur­
ers is carbon deposit build-up caused by the type
of gasoline you use.
Although gasol ine grades differ from one manu­
facture r to another, they have certa in things in
common . All gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves. A l­
though most gasoline brands include additives to
keep engine and fuel systems clean, they are not
equally effective .
Audi recommends using TOP TIER Detergent Gas ­
oline. For more information on TOP TIER Deter-

The catalytic conve rter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi ­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critically im­
portant for the life of the catalytic converter and
proper functioning of the engine .
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result in burns.
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in contact with dry grass, brush, fue l spill or
other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on o r near the exha ust man i­
fold, exhaust pipes, catalyt ic converte r or
heat s hields. Dur ing driv ing, the subs tance
u5ed for undercoating could overheat and
cause a fire .
(D Note
-Be awa re that just one tank f illing wit h lead­
ed
f uel will a lready se riously degrade the
performance of the c ata lytic conver ter.
- Do not exceed the co rrect engine oil leve l

-Do not d rive until the fuel tank becomes
complete ly empty. The eng ine could misfi re.
U nburned f uel co uld also ge t in to the e x­
haust system and this could ca use the cata ­
l ytic converter to overheat.
- Do no t sw itch off the ignition wh ile the vehi­
cle is moving.
- Do not con tinue to oper ate yo ur vehicle un­
der these cond itions, as o therwise fue l can
r each the catalytic converte r. This cou ld re­
su lt in overheating of the converter, requir­
i ng its replacement.

- Lack of prope r maintenance as we ll as im­
p roper use of the vehicle will impair the
f u nction of the emission control system
and could lead to damage.
@ For the sake of the environment
Even when the Emission Control System is op­
erating properly, the exha ust gas can have a
