ZA\ 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 
could 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 
Audi Service Facility. If this brake fluid is not 
available, another high-grade brake fluid of 
equivalent quality may be used, and it must

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 allow any brake fluid to come into 
contact with the vehicle paint, because it 
will corrode the paint.

Battery 
eae elec acl) 
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\. 
Batteries with different technologies are instal- 
led in your vehicle: 
— 12 volt vehicle battery (for example, for basic 
power supply) > page 238, 12 Volt vehicle bat- 
tery 
— High-voltage battery (for example, for electric 
drive system, climate control) > page 108, In- 
troduction 
Not running the vehicle for long periods of 
time 
When the vehicle is not used for long periods, the 
12 Volt vehicle battery will drain little by little. To 
ensure that the vehicle can still be started, the 
electrical equipment will be limited or switched 
off. Some convenience functions, such as interior 
lighting or power seat adjustment, may not be 
available under certain circumstances. The con- 
venience functions will be available again when 
you establish drive ready mode. 
Even when electrical equipment is switched off, 
the equipment can still drain the 12 Volt vehicle 
battery if the vehicle is not driven for long peri- 
ods of time. Deep draining results in a chemical 
reaction that destroys the inside of the battery. 
To reduce the risk of this, the battery must be 
charged monthly by  an authorized Audi dealer or 
authorized Audi Service Facility > page 239. Con- 
tact an authorized Audi dealer or authorized Audi 
Service Facility for more information. 
Winter operation 
Cold weather places an especially high load on 
the 12 Volt vehicle battery. Have the battery 
checked by an authorized Audi dealer or author- 
238 
ized Audi Service Facility before cold weather be- 
gins. 
  
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. 
@) Note 
If the vehicle will be parked for long periods 
of time, protect the 12 Volt vehicle battery 
against the cold so that it will not “freeze” 
and become damaged. Have the battery 
charged by an authorized Audi dealer or au- 
thorized Audi Service Facility > page 239,
