Cooling system
Coolant
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac­
tory. This coo lant must not be not changed.
The coolant level is monitored through the. in­
dicator light
¢page 26. However , we do recom­
mend occasionally check ing the coo lant level
manually.
If you must add coolant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freez ing and
corros ion protection agents. Only use the follow­
ing coolant addit ives . These additives may be
mixed with each other.
Coolant additive Specification
G13
TL 774 J
G12++ TL 774 G
The amount of coo lant add itive that needs to be
mixed with water depends on the climate where
the vehicle will be operated.
If the coolant addi­
tive percentage is too low, the coolant can freeze
and damage the engine.
Coolant Freeze protec-
additive tion
Warm min. 40% m in. -13 °F
regions max. 45% (-25 °C)
Cold min. 50% max

regions max. 55% (-40 °C)
(D Note
-Before the start of winter, have your author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate . Th is is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive . You could damage the en-

gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant add it ive as soon as possi­
ble.
- Only refill with new coolant .
- Radiator sealant must not be mixed with
the coolant.

A WARNING
-
-The cooling system is under pressure. Do
not open t he coolant expansion tank ca p
when the eng ine is hot. This inc reases the
risk of bu rns .
- The coolant add itive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the o rigina l container
and away from children. There is a risk of
po isoning .
- When working in the eng ine compartmen t,
r emembe r that the rad iator fan ca n switch
on even if the ign ition is swi tc h ed off, which
in creases the risk of in jury.
(D 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 no t
cont inue driv ing. See an authorized Audi deal­
er or author ized Audi Se rvice Facility for assis­
tance .

¢ page 219.
The fluid level may drop slightly afte r some t ime
due to t he automatic adjustme nt of the brake
pads. This is not ca use for a larm.
If the brake fluid level falls considerably below
the
" M IN " mark, the bra ke warn ing/ indica tor
li gh t (U.S. models:

will come on ¢
page 15 and¢ page 25. Do not
continue to ope rate the veh icle. The comp lete
brake system shou ld be thoroughly checked by an
a uthor ized Audi dealer or qualified workshop and
the cause corrected. If the brake fluid level is too l ow, the brake warn ing/ indicator light w ill illumi­
nate. Contact a n author ized Audi dealer
immedi­
ately .
Chang ing brake fluid
Have the brake fluid changed by an experienced
technician .
Brake fluid absorbs moisture from the air. If the
water content in the brake fluid is too high, cor­
rosion in the brake system may result after ape ­
riod of time . The boiling po int of the brake fluid
will a lso decrease considerably and decrease
bra king pe rformance.
Therefore, the brake fluid must be changed
every
two years .
Always use new brake f lu id which con­
fo rms to Federa l Moto r Vehicle S tandard " FMVSS
116 DO T 4".
The brake fluid reservoir can be diff icult to reach,
therefore, we recommend that you have the
brake fluid changed by your author ized
Audi
dealer .
Your dealer has the correct tools, the
right brake fluid a nd the know -how to do t his for
you . ..,.

Checking and Filling
-Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery.
- Never charge a frozen battery . It may ex­
plode because of gas trapped in the ice. Al­
low a frozen battery to thaw out first.
- Do not reuse batteries which were frozen .
The battery housing may have cracked and
weakened when the battery froze .
- Charge the battery in a well ventilated area.
Keep away from open flame or electrical
spark . Do not smoke. Hydrogen gas generat ­
ed by the battery is explosive .
- To reduce the danger of explosion, never
connect or disconnect charger cables while
the charger is operating .
- Fast charging a battery is dangerous and should only be attempted by a competent
technician with the proper equipment .
- Battery acid that may spill during charging should be washed off with a solution of
warm water and baking soda to neutralize
the acid.
(D Note
Never use a fast charger as a booster to start
the engine. This will seriously damage sensi­
tive electronic components, such as control
units , relays , radio, etc., as well as the battery
charger.
Battery replacement
The new battery must have the same specifica­
tions and dimensions as the original equipment
battery.
Intelligent energy management in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
~ page 192. The intelli­
gent energy management system will keep the
engine battery charged better then vehicles with­
out this system. To mak e sure the additional
electrical energy is available once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture only (the same as those installed at the
time your vehicle was delivered) . Specifications
228
are listed on the battery housing. Your author­
ized dealer must cod e the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re­
placing the battery.
If it is not possible to use a battery of this type,
the new battery must have the same capacity,
voltage (12 volts), amperage, construction and plug sealing.
When installing the battery, make sure the igni­
tion and all electrical consumers are turned off.
([) Note
- Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of bat­
tery can cause problems in the vehicle elec­
trical system. When replacing the vehicle battery, always install one with the same
specifications as the original battery.
@ For the sake of the environment
Because of the problem of proper disposal of
a battery, we recommend your authorized
Audi dealer change the battery for you. Bat­
teries contain sulfuric acid and lead and must
always be disposed of properly in compliance
with all environmental regulations. Disposing
of vehicle batteries improperly is
very danger­
ous to the environment.

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry . A vehicle
that is overloaded will not handle
well and is more difficult to stop.
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
