from the coolant boili ng through overheating
and being pushed out of the cooling system.
.&_ WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the eng ine is hot. This inc reases the
risk of burns.
- The coo lant add itive and the coolant can be
dangerous to you r healt h. For this reason,
keep t he coolant i n the o rigi nal container
and away from children. There is a risk of
poiso ning.
- When working in the engine compartment,
remember t hat the radiator fan can sw itch
o n even if the ign ition is swi tched off, which
increases the risk of i njury.
@ Note
Do not add coo lant if the expansion tank is
empty. There may be a ir in the coo ling sys­
t em, wh ich increases t he risk of engi ne dam­
age . If this is the case, do not continue driv­

Checking the brake fluid level
"' Read the brake fluid level on the brake fluid
reservoir ¢
page 316, fig . 260. The brake fluid
level must be between the MI N and MAX mark­
ings ¢,&. .
Chec king and Filling
The brake f lu id leve l is moni to red automatically .
Changing the brake fluid
Have the brake fluid changed regularly by an au­
t h ori zed Audi dea le r or a uthor ized Audi Service
F ac ility.
A WARNING
-
- I f the b rake fl uid level is below t he MIN
marking, it can impair the brak ing effect
and d riving safety, which increase the risk of
an accident. Do not continue dr iving. See an
author ized Audi dealer or author ized Audi
Serv ice Facility for assistance.
- If the b rake fl uid is old, b ubbles may form
in the brake system dur ing heavy bra king.
This wo uld impair braking performance and
driving safety, which increases the r isk of an
accident.
- To ensure the brake system functions cor­ rectly, only use brake f luids tha t comply
wit h VW standard S0 l 14 o r
F M VSS -116 DOT 4 .
(D Note
-If the brake flu id leve l is above the MAX
ma rking, bra ke f luid may leak o ut over the
edge of the reservo ir and resul t in damage
t o the vehicle.
- Do not ge t any brake fl uid on the vehicle
pai nt, because it w ill corrode the paint.
Battery
General warnings about batteries
Because of the complex power supply, all work
on batter ies such as d isconnecting, replacing,
etc., sho uld
only be performed by an authorized
Audi dealer or author ized A udi Se rvice Facility
¢ &_ .
The term "veh icle battery" refers to the 12 Volt
batte ry in your vehicle.

Checking and Filling
Detailed warnings for the vehicle battery:
~
Always wea r eye protection.
~
Battery acid is highly corrosive. Always
wea r protect ive g loves and eye pro tect io n .
.
®
Fire, sparks, open flame and smok ing are
forb idden .
~
A highly explosive mixture of gases can
form when charging batteries.
®
Always keep childre n far away from bat-
tery electrolyte and the batte ry .
~
Always follow the instructions in the oper-
ating manual.
A WARNING
All wo rk on the batte ry o r electrical system in
yo ur vehicle can result in inju ries, chemical
burns, accidents or burns. Because of this, all
wor k must be performed
only by an author­
ized Audi dealer or authorized Audi Service
Facility.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and re lated acces­
sories contain lead and lead compounds,
chemica ls known to the State of California
to cause cancer and reproductive problems.
Wash hands after handling .
@ Note
-If the vehicle will be parked for long periods
of time, protect it against the cold so that it
will not be destroyed by "freezing"
<=>page 323.
-There are electrical components under the
cargo floor behind a trim pane l that warm
up during operation. To reduce the risk of
the components overheat ing, do not store
objects such as blankets under the cargo
floor . If they overheat, the components wi ll
switc h off temporarily. This will be ind icat ed
by a message in the instrument cluster, un­
til the temperature returns to normal.

@ For the sake of the environment
i Batteries contain polluting substances such
as sulfur ic acid and lead. Contact an author­
i zed Audi dealer or authorized Audi Service
Fac ility for more informat ion.
Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If you do not drive your vehicle for severa l days or
weeks, electrical equ ipment is gradually sca led
back or switched off. This reduces energy use and
ensures the vehicle will be able to start after long
periods of
time<=> page 145 . Some convenience
funct ions, such as interior lighting or power seat
adjustment, may not be available under certain
circumstances . These convenience functions will
be available again once you switch t he ignition on
and start the engine .
Even when electrical equipment is switched off,
the equipm ent can still drain the vehicle battery
if the vehicl e is not driven for long periods of
time. Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery.
The vehicle battery must be charged every month
to reduce the risk of this happening
<=> page 323.
Contact an authorized Aud i dealer or authorized
Audi Service Fac il ity for more information.
Winter operation
Cold weather places higher demands on the vehi­
cle battery. This results in reduced starting abili­
ty. Have the vehicle battery checked by an au­
thorized Audi dealer or authorized Audi Service
Fac il ity before the cold time of year .

A WARNING
-A highly explosive mixtu re of gases can form
whe n cha rging batter ies. O nly charge the
vehicle ba tte ry in well-ven tilated are as.
- A dra ined vehicle battery can freeze at tem­
peratu res a round 3 2
QF (0 QC). A frozen or
t hawed veh icle bat tery m ust not be charged
and must not be used anymore. If ice forms,
the battery housing can crack and battery electrolyte can leak out, which increases the
risk of an explosion and chemical b urns .
Chec king and Filling
Contact an author ized Audi dealer or au ­
thorized Audi Service Facility for more infor­
mat ion.
- Do not connect or disconnect the charging
cable wh ile charging because this increases
the risk of an explos ion.
(D Tips
- Only charge the veh icle battery through the
connect ions in the engine compartment .
- Read all of the manufacturer's instructions
for the charger before charging the vehicle battery.

To reduce the risk of lime scale deposits on the
spray no zzles, use clean water with low amounts
of calcium . Always add w indow cleaner to the wa­
