appears, contact your authorized
Audi deale r or other qualified workshop
to have excess oil extrac ted if necessary.
- Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.

244 Checking and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention .
The cooling system has been filled at the fac­ tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-basedcoolant additive G12++ antifreeze
with anticorrosion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture bo th assures the necessary frost protec­
tion and protects metal components in the
engine's coo ling system from corrosion and
scaling. It also raises the boiling point of the
coolant.
Do not reduce the concentration of the cool­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50 % but not more than 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and engine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- - 31°F (- 35 °C) USA
- -40°F ( - 40°C) Canada.
You can mix the G12 ++ coolant additive with
other additives (G12+ or G12). Always check
with your authorized Audi dealer.
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 237.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your vehicle is sufficient to meet the cli
­
mate conditions. This is especia lly impor­
tant if you live in a reg ion where the win ­
ter is extreme ly cold. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ (check the label) for your
vehicle . This coolant additive is availa­
b le at authorized Audi dealers . Other
types of antifreeze can significant ly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Add ing radiator repair fluid may adverse ­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.

-Always wear eye protection. Do not let
battery acid or any lead particles get on
your skin or clothing. Shield your eyes .
Explosive gases can cause blindness or
other injury.
- Battery acid contains sulfuric acid . Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because acid
could leak out of the ventilation open­
ings.
- If you get battery acid in your eyes or
on your skin, immediately rinse with
cold water for several minutes and get
medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg-
ative cables .
= When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would cause the battery to heat up very quickly,
which could lead to damage or explosion and personal injury.
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury .
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground ca­ ble .
- Before performing any work on the elec­
trical system, switch off the engine and
ignition as well as any electrical equip ­
ment. The negative cable on the battery
must be disconnected . If you are just go­
ing to replace a light bulb, then it is
enough to switch off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you will set off the alarm.
Checking and filling 249
-When disconnecting the battery, first
disconnect the negative cable and then
the positive cable.
- Before reconnecting the battery, make
sure all electrical consumers are switch­
ed off. Reconnect the positive cable first
and then the negative cable . Never inter ­
change the cables -this could start a fire!
- Never charge a frozen or a thawed-out
battery . It could explode! If a battery has
frozen , then it must be replaced . A dis­
charged battery can freeze over at 32°F
(QOC),
-Make sure the vent hose is always attach­
ed to the opening on the side of the bat­
tery .
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways replace a damaged battery.
&_ WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive problems. Wash hands after han­ dling.
(D Note
- Do not disconnect the vehicle battery
when the ignition is switched on or when the engine is running, otherwise, you will
damage electronic components in the
electrical system.
- If your vehicle is going to stand for a
long period of time without being driven,
protect the battery from "freezing", oth­
erwise it will be damaged and will then
have to be replaced.
