compartment. This increases the risk  of 
burns. The cooling system is under pressure. 
When you no longer see or hear steam or 
coolant escaping, you may open the engine 
compartment with caution. 
— When working in the engine compartment, 
remember that the radiator fan can switch 
on even if the ignition is switched off, which 
increases the risk  of injury. 
— Coolant additive and coolant can be danger- 
ous to your health. For this reason, store the 
coolant in the original container and away 
from children. There is a risk of poisoning. 
  
    
@ Note 
Do not continue driving if the coolant expan- 
sion tank is empty. Do not add any coolant, 
because air could enter the cooling system 
and damage the engine. See an authorized 
Audi dealer or authorized Audi Service Facility 
for assistance.

al information. 
Checking the brake fluid  level 
Read the brake fluid  level  on the brake fluid res- 
ervoir > page 223, fig. 167. The  brake fluid level 
must be between the MIN and MAX markings 
>A. 
The  brake fluid level is monitored automatically. 
Message 
GG / oo 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. 
  
Z\ 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 
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 allow any brake fluid to come into 
contact with the vehicle paint, because it 
will corrode the paint.

Battery 
Battery general information 
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\. 
230 
Multiple batteries with different technologies 
may be installed in your vehicle: 
— Vehicle battery (for example, for starting the 
engine, basic power supply) > page 231, Lead 
battery or > page 231, Other battery types 
— Auxiliary battery (for example, for recuperation 
or optional equipment) > page 231, 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 107. Some convenience functions, such 
as interior lighting or power seat adjustment, 
may not be available under certain circumstan- 
ces. 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 
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 232. 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, chemi- 
cal burns, accidents, or burns. Because of 
this, all work must be performed only by an 
authorized Audi dealer or authorized Audi 
Service Facility.

Messages 
g Please  add washer fluid 
Fill the washer fluid for the windshield washer 
system and the headlight washer system* when 
the ignition is switched off. 
@ Note 
— The concentration of anti-freezing agent 
must be adjusted to the vehicle operating 
conditions and the climate. A concentration 
that is too high can lead to vehicle 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. 
Service interval display 
The service interval display detects when your ve- 
hicle is due for service. 
The service interval display works in two stages: 
— Inspection or oil change reminder: after driv- 
ing a certain distance, a message appears in the 
instrument cluster display each time the igni- 
tion 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 oil change interval 
or both intervals at the same time, the mes- 
sage Inspection due! or Oil change due! or Oil 
change and inspection due! will appear briefly 
after switching the ignition on or off. 
Checking service intervals 
You can check the remaining distance or time un- 
til  the next oil change or next inspection in the 
Infotainment system. 
Select on the home screen: VEHICLE > Settings 
& Service > Service intervals. 
Resetting the indicator 
An authorized Audi dealer or authorized Audi 
Service Facility will reset the service interval dis- 
play after performing service. 
If you have changed the oil yourself, you must re- 
set the oil change interval. 
Select on the home screen: VEHICLE > Settings 
& Service > Service intervals > Reset oil change 
interval. 
@) Note 
— Only reset the oil change indicator if the oil 
was changed.

and Tires 
General information 
> Check your tires regularly for 
damage, such as punctures, 
cuts, cracks, and bulges. Remove 
foreign objects from the tire 
tread. 
>If driving over curbs or similar 
obstacles, drive slowly and ap- 
proach the curb at an angle. 
> Have faulty tires or rims re- 
placed immediately. 
>Protect your tires from oil, 
grease, and fuel. 
>Mark tires before removing 
them so that the same running 
direction can be maintained if 
they are reinstalled. 
>Lay tires flat when storing and 
store them ina cool, dry location 
with as little exposure to light as 
possible. 
  
J WARNING 
—Never drive faster than the 
maximum permitted speed for 
your tires. This could cause the 
tires to heat up too much. This 
increases the risk of an  acci- 
dent because it can cause the 
tire to burst. 
      
234 
  
  
—Always adapt your driving to 
the road and traffic condi- 
tions. Drive carefully and re- 
duce your speed on icy or slip- 
pery roads. Even winter tires 
can lose traction on black ice. 
  
() Note 
—Please note that summer and 
winter tires are designed for 
the conditions that are typical 
in those seasons. Audi recom- 
mends using winter tires dur- 
ing the winter months. Low 
temperatures significantly de- 
crease the elasticity of summ- 
er tires, which affects traction 
and braking ability. If summer 
tires are used in very cold tem- 
peratures, cracks can form on 
the tread bars, resulting in 
permanent tire damage that 
can cause loud driving noise 
and unbalanced tires. 
—Burnished, polished or 
chromed rims must not be 
used in winter driving condi- 
tions. The surface of the rims 
does not have sufficient corro- 
sion protection for this and 
could be permanently dam- 
aged by road salt or similar 
substances.
