Follow the safety precautions > page 203, Gener-
al information.
Checking the brake fluid level
Read the brake fluid level on the brake fluid res-
ervoir > page 205, fig. 142. The brake fluid level
must be between the MIN and MAX markings
>A.
The brake fluid level is monitored automatically.
Message
GG / @ Brakes: stop vehicle and check brake
fluid level
Stop the vehicle and check the brake fluid level.
See an authorized Audi dealer or authorized Audi
Service Facility for assistance.
Changing the brake fluid
Brake fluid should be changed at regular inter-
vals. Have the brake fluid changed by an author-
ized Audi dealer or authorized Audi Service Facili-
ty. The authorized Audi dealer or authorized Audi
Service Facility will inform you of the replace-
ment intervals.

/\ WARNING
— If the brake fluid level is below the MIN
marking, it can impair the braking effect and
driving safety, which increase the risk of an
accident. Do not continue driving. See an au-
thorized Audi dealer or authorized Audi
Service Facility for assistance.
— If the brake fluid is old, bubbles may form in
the brake system during heavy braking. This


would impair braking performance and driv-
ing safety, which increases the risk of an ac-
cident.
— The brake fluid in your vehicle must meet
the standard VW 501 14 and is available at
an authorized Audi dealer or authorized Au-
di Service Facility. If this brake fluid is not
available, another high-grade brake fluid of
equivalent quality may be used, and it must
meet the U.S. Federal Motor Vehicle Stand-
ard (FMVSS) 116 DOT 4, Class 6.

@) Note
— If the brake fluid level is above the MAX
marking, brake fluid may leak out over the
edge of the reservoir and result in damage
to the vehicle.
— Do not get any brake fluid on the vehicle
paint, because it will corrode the paint.

Battery
rae Le cel)
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 213, Lead
battery or > page 213, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 213, Other bat-
tery types
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be reduced or switched off
= page 87. Some convenience functions, 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 the ignition on and start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
212
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 213. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places higher demands on the bat-
tery. This results in reduced starting ability. Have
the battery checked by an authorized Audi dealer
or authorized Audi Service Facility before cold
weather begins.

ZA\ WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical
burns, accidents, or burns. Because of this, all
work must be performed only by an author-
ized Audi dealer or authorized Audi Service Fa-
cility.

ZA WARNING
California Proposition 65 Warning:
— Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling.
C) Note
— If the vehicle will be parked for long periods
of time, protect the battery against the cold
so that it will not be destroyed by “freezing”
= page 213, Charging the battery.
— There are electrical components under the
cargo floor behind a trim panel that warm
up during operation. To reduce the risk of
the components overheating, do not store
objects such as blankets under the cargo
floor. If the components overheat, they will
switch off temporarily. This will be indicated
by a message that will be displayed in the
instrument cluster until the temperature re-
turns to normal.

Checking and Filling

> Open the cover on the positive terminal
> fig. 147.
> Clamp the terminal clamps on the charger cor-
rectly onto the ground point ©) and the positive
terminal @).
> Insert the power cable for the charging device
into the socket and switch the device on.
> At the end of the charging process, switch the
charger off and pull the power cable out of the
socket.
> Now remove the charging device terminal
clamps.
> Close the cover on the positive terminal.
> Close the hood > page 204.

Z\ WARNING
— A highly explosive mixture of gases can form
when charging batteries. Only charge the
battery in well-ventilated areas.
— A drained battery can freeze at tempera-
tures around 32 9F (0 2C). Do not charge or
use a frozen or thawed battery. If ice forms,
the battery housing can crack and battery
electrolyte can leak out, which increases the
risk of an explosion and chemical burns.
Contact an authorized Audi dealer or author-
ized Audi Service Facility for more informa-
tion.
— Do not connect or disconnect the charging
cable while charging because this increases

the risk of an explosion.

@ Tips
Read all of the manufacturer's instructions
for the charger before charging the battery.

Windshield washer
system

RAZ-0362



Fig. 148 Engine compartment: windshield washer fluid
reservoir cap
Follow the safety precautions > page 203, Gener-
al information.
The windshield washer fluid reservoir <> contains
the cleaning solution for the windshield and the
headlight washer system > fig. 148, > page 205.
The reservoir capacity can be found in
=> page 264.
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
anti-freezing agent should be added to the water
so that it does not freeze.
Messages
ES Please add washer fluid
Fill the washer fluid for the windshield washer
system and the headlight washer system* when
the ignition is switched off.
C@) Note
— The concentration of anti-freezing agent
must be adjusted to the vehicle operating
conditions in the respective climate. 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.
— Do not use a glass cleaner that contains
paint solvents, because this could damage
the paint.
