-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circ uit interrupt ­
er must only be performed by a qualified
technicians who have the experience, in ­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all app licab le safety precautions
must be followed .
@) For the sake of the environment
Undeployed airbag modu les a nd pretension ­
ers might be classified as Perch lorate Materi­
al -special handling may apply, see
www.dtsc .ca.gov/hazardouswaste/perchlo­
rate. When the vehicle or parts of the re­
straint system including airbag modules and
safety belts with pretensioners are scrapped,
all applicable laws and regulations must be
observed. Your authorized Audi dealer is fa­
m iliar with these requi rements a nd we recom­
mend t hat you have you r dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash . For example, using tire-r im
comb inat ions not approved by Audi, lowering the
ve hicl e, chang ing the stiffness of the suspens io n,
in clud ing the spr ings, suspens ion str uts, shock
absorbers et c. can change the forces that are
measured by the airbag sensors and sent to the
e lectronic contro l unit. Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in wh ich it would not deploy if
the changes had not been made. Other ki nds of
changes may reduce the fo rce levels meas ured by
the sensors and prevent the airbag from deploy­
in g when i t should .
Airbag sys tem
A WARNING
-Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious persona l injury in a
crash.
- Never install suspension components that
do not have the same pe rformance charac­
teristics as the components o rigina lly ins tal­
led on your vehicle.
- Never use tire-rim combinations t hat have
not been approved by Audi.
Knee airbags
Description of knee airbags
The knee airbag system can provide supplemen­
tal protection to prop erly restrained front sea t

_& WARNING
- T urn the engine off.
- Switch the ign ition off .
- Set the parking brake .
- Place the selector lever in the P pos ition.
- let the engine cool down.
- Never open the hood when there is steam or coolant escaping from the engine compart­
ment, because there is a risk that you could
be burned . Wait until no steam or coolant is
escaping .
- Keep ch ildren away from the engine com­
partment .
- Never spill flu ids on a hot engine. These flu­
ids (such as the freeze protection contained
in the coolant) can catch fire .
- Avoid short circu its in the electrical system,
especially to the battery .
- When working in the engine compartment,
remember that the rad iator fan can sw itch
on even if the ign ition is switched off, which
increases the risk of pe rsonal injury .
- Never open the cap on the coolant expan­ sion tank when the eng ine is warm. The
cooling system is under pressu re .
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances. This increases the risk of
burns.
- If tests need to be performed w ith the en­
gine running, there is additional danger d ue
244
to moving components (such as the ribbed
be lt, alternator and rad iator fan) and from
the high voltage ignition system.
- Do not press the acce lerator pedal inadver­
tently if a gear is selected when the vehicle
is stationary and the engine is running. Oth­
erwise, the vehicle will start to move imme ­
diately and this could result in an accident .
- Pay attent ion to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames .
- Always have a working fire extinguisher
nearby
- All work on the battery or elect rical system
in your vehicle can result in injuries, chemi­
cal b urns, acc idents or burns . Because of
this, all work must be performed
onl y by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk o f electric shock and in ­
jury, never touch the following components
when the engine is running or is being start•
ed:
- Ign ition cable
- Other components in the electronic high -
vo ltage ign ition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginn ing
work and do not wear clothing that can hang down into the engine .
- Lim it your exposure to exhaust and chemi­
cals to as short a time as possible

A WARNING
-A highly explosive mixture of gases can form
when charging batteries. Only charge the
vehicle battery in well-ventilated areas.
- A drained battery can freeze at tempera­
tures around 32 °F (0 °C). A frozen or
thawed vehicle battery must not be charged
and must not be used anymore. The battery
housing can crack and battery acid can leak
out if ice forms, which increases the risk of
an explosion and chemical burns . Contact an
Checking and Filling
authorized Audi dealer or authorized Audi
Service Facility for more information.
- Do not connect or disconnect the charging
cable while charging because this increases
the risk of an explosion.
@ Tips
- Only charge the vehicle battery through the
connections in the engine compartment.
- Read all of the manufacturer's instructions
for the charger before charging the vehicle
battery.
Windshield washer system
Fig. 19S Engine compartment: washer fluid reservoir cap
The windshield washer reservoir{!} contains the
cleaning solution for the windshield and the
headlight washer system*¢
page 246, fig. 189.
The reservoir capacity is found in ¢ page 299.
To reduce the risk of lime scale deposits on the
spray nozzles, use clean water with low amounts
of calcium. Always add window cleaner to the wa­
ter. When the outside temperatures are cold, an
ant i-freezing agent should be added to the water
so that it does not freeze.
(D Note
-The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective cl imate. A con­
centration that is too high can lead to vehi-
cle damage.
- Never add radiator anti-freeze or other addi-
tives to the washer fluid. .,.

Service interval display
The service interval display detects when your ve­
hicle is due for service.
The service interva l display works in two stages:
- Inspection or oil change reminder: after a cer-
tain distance driven, a message appears in the
Infotainment system display each time the ig­
nition is switched on or off . The remaining dis­
tance or time is displayed briefly.
- Inspection or oil change due: if your vehicle
has reached an inspection or oi l change interval
or both intervals at the same time, the mes­
sage
Inspection due! or Oil change due! or Oil
change and inspection due!
appears briefly af­
ter switching the ignition on/off .
Checking service intervals
You can check the remaining distance or time un­
til the next oil change or next inspection. Select
in the Infotainment system: the !MENU ! button>
Vehicle > left control button > Service & checks >
Service intervals.
{[) Note
-Following the service intervals is critical to
maintain ing the service life and value of
your vehicle, especially the engine. Even if
the mileage on the vehicle is low, do not ex­
