The coolant leve l is monitored through the. in­
dicator light
c::> poge 14. However, we do recom­
mend occasionally check ing the coo lant level
manually.
If you m ust add coolant, use a m ixture o f water
and coolant additive . M ixing the coolant additive
w ith d istilled water is recommended.
Coolant additive
The coolan t addi tive is made of ant i-freez ing and
corrosion protection agents. Only use the fo llow­
i n g coo lant additives . These additives may be
mixed wit h each other .
Coolant additive Specification
Gl3 TL774J
Gl2++ TL 774 G
The amount of coo lant add itive that needs to be
mixed with water depends on the climate where
the veh icle will be ope rated. If the coolant addi­
tive percentage is too low, the cool ant can freeze
and damage the engine.

(D Note
-
Befo re the start of winter, have your author­
i zed Audi dealer or author ized Audi Se rvice
Facility check if the coolant additive in yo ur
vehicle ma tches the percen tage approp riate
fo r th e climate. This is especially import ant
whe n driving in co lder climates .
-If the approp ria te coolant addi tive is no t
available in an emergency, do no t ad d any
other additive. You co uld damage the en­
gine. If this happens, only use wate r and re­
store the correct mixture ratio with the
spec ified coolant additive as soon as possi­
ble.
- Only refill with new coo lant .
- Radiator sealant must not be mixed with
the coo lant .

Observe the safety prec autions c::> A in Working
in the engine comportmen t on page 198.
Checking the engine coolant level
Park the vehicle on a level surface.
.,. Switch t he ignit ion off.
.,. Read the coolant level on the coolant expansion
tank
c::> page 201, fig . 182. The coolant level
must be between the MIN and MAX mark ings
when the engine in cold. When the eng ine is
warm it can be slightly above the MAX marki ng.
Adding coolant
Requirement: there must be a residua l amount of
coolant in the expansion tank
c::> (D .
.,. Let the eng ine cool down .
.,. Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
c::> .&_ .
.,. Add coo lant m ixed in the cor rect rat io
c::> page 204 u p to the MAX mark ing.
.,. Ma ke sure that the f luid level remains stab le.
Add mo re coolant if necessary.
.,. Close the cap sec urely.
Coo la nt loss usually i ndicates there is a lea k. Im­
med iate ly drive you r ve hicle to a n author ized
Audi dealer or authorized A udi Se rvice Faci lity
and have the cooling system inspected. If the
cooling system is not leak ing, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system.

Checking and Filling
_& WARNING
-The cooling system is under pressure. Do
not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning .
- 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.
CD Note
Do not add coolant if the expansion tank is
empty. Air could enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance .
Brake fluid
Fig. 185 Engine compartment : ca p on brake fl uid re servoir
Observe the safety precautions c::> .&. in Working
in the engine comportment on page 198.
Checking the brake fluid level
• Read the brake fluid level on the brake fluid
reservoir
c::> page 201, fig . 182. The brake fluid
level must be between the MIN and MAX mark­
i n gs c::> .,&. .
The brake fluid level is monitored automatically .
206
Changing the brake fluid
Have the brake fluid changed regularly by an au­
thorized Audi dealer or authorized Audi Service Facility.
_& 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
authorized 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 driving safety, which increases the risk of an
accident .
- To ensure the brake system functions cor­
rectly, only use brake fluids that comply
with VW standard 50114 or FMVSS-116 DOT 4.
CD 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.

General warnings about batteries
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
c:::, &.
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Detailed warnings for the vehicle battery:
®) Wear eye protection.
~ Battery acid is highly corrosive. Wear pro-
~ tect1ve gloves and eye protection. ..,.

@
Fire, sparks, open flame and smoking are
forb idden.
~
A highly explosive mixture of gases can
form when charging batteries.
®
Keep children away from battery acid and
batteries.
A 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 Aud i dealer or authorized Aud i Service
Facility.
A 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 reproduct ive problems.
Wash hands after handling.
(D Note
Protect the vehicle battery against freezing if
the vehicle will be parked for long periods of
time so that it is not destroyed by "freezing"
c:>page207.
@ For the sake of the environment
~ Batteries contain poll uting substances such
as sulfuric acid and lead. Contact an author­
ized Audi dealer or authorized Audi Service
Facility for more information.
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 several days or
weeks, e lectrical equipment is gradually scaled
back or switched off. This reduces energy use and
ensures the veh icle will be able to start after long
periods of time
c:> page 124. Some convenience
Checking and Filling
functions, such as interior lighting or power seat
adjustment, may not be available under certa in
c ir cumstances. 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 dra in the vehicle 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 vehicle battery .
T he veh icle battery must be charged every month
to reduce the risk of this happening
c:> page 207 .
Contact an authorized Aud i dea ler or authorized
A udi Service Facility for more information .
Winter operation
Cold weather places higher demands on the vehi ­
cle battery . This results in reduced starting abili­
ty. Have the veh icle battery checked by an au­
thorized Audi dea ler or authorized Audi Service
Facility before the cold time of year.
Charging the vehicle battery

gency tire* /spare tire*. A lways
maintain the maximum temper­
ature that is specified for the
tire.
