Depending on the way the vehicle is driven
and the operating conditions, oil consumption
can be up to 1 quart per 600 miles (0.8 liter
per 1,000 km). Consumption may be higher
within the first 3,000 miles (5,000 km).
The oil level indicator in the MMI* Display
is only an information display. If the oil
level is too low, a minimum oil warning ap­
pears in the instrument cluster. Add oil

el may be slightly above the "MAX" marking.
.,. The MAX marking may be covered with a
maximum of 1 mm of coolant when yo u
fill
coolant .
.,. Twist the cap on again tightly.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 209.
To obtain an accurate read ing, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an electric coolant level sensor .
When the coo lant level is too low, the warning

page 18 wi ll
b lin k until you add coo lant and the level has
been restored to norma l. Even though there is
an electric coolant level sensor, we sti ll rec­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling
system . In the event of coolant loss, the cool ­
i n g system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
Checkin g and fillin g 215
In a sealed system, losses can occur on ly if
the boiling point of the coolant is exceeded as
a resu lt of overheating.
Adding coolant
Rep lacement engine coolant must confo rm to
exact specificat ions¢
page 214, Coolant .
We recommend using only coo lant add itive
Gl2++, Gl3 or i n an emergency Gl 2+ . Do not
use a different add itive. In an emergen cy use
plain water until you can ge t the correct addi­
tive and can restore the correct ra tio. This
sho uld be done as soon as possib le .
If you have lost a cons iderab le amount o f
coolant, then you sho uld add cold ant ifreeze
and co ld water on ly when the engine is cold.
A lways use
new engine coo la nt when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be fo rced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
_& WARNING
- Th e cooling system is un der pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these ste ps.
- Turn off the engine and allow it to coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap w ith a large, th ic k rag.
- Turn the cap s lowly and very carefully
i n a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being bu rned, do not spill an­
tifree ze or coolant o n the ex haust sys­
tem o r hot engine p arts. Under ce rtain
con ditio ns, the ethy lene glycol in en­
gine coolant can catch fire.
- Antifreeze i s poisonous. Always s tore an­
tifreeze in its original container an d well
out of the reach of children .

216 Check ing and filling
-If you drain the coolant, it must be
caught and safely stored in a proper con­
tainer clearly marked "poison".
(D Note
-Do not add any type of radiator leak seal­
ant to your vehicle's engine coo lant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .
- Coolant pollutes the environment and
could cause an engine fire . Excess cool­
ant wil l be forced out through the pres­
s u re re lief valve in the cap when the en­
gine becomes hot.
- If, in an emergency , only water can be
added, the correct ratio between wate r
and antifreeze
c::> page 214 must be re ­
stored as soon as possib le .
@ For the sake of the environment
Dra ined coolant should not be reused. Al­
ways dispose of used coolant while observ­ ing all environmental regulations.
Radiator fan
The radiator fan switches on automatically by
itself.
The radiator fan is dr iven by the engine via the
V-be lt . T he viscous clutch regulates the speed
of the fan accord ing to the temperature o f the
coolant .
A n auxiliary e lectr ic radiator fan* switches on
and off depending on coolant temperature
and other vehi cle operating conditions.
After you switch the engine off, the auxiliary
fan can cont inue runn ing for up to 10 minutes
- even with the ignition off.
It can even sw itch
on again later by itself
c::> .&. , if
- the temperature of the engine coolant rises
due to the heat bu ild-up from the eng ine in
the engine compartment, or -
the engine compa rtment heats up because
the vehicle is parked in intense sunlight.
.&_ WARNING .........
- To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
contro lled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan sw itches on au­
tomatically when the engine coo lant
reaches a certain temperature and will
continue to run until the coolant temper ­
ature drops .
Brake fluid
Checking brake fluid level
The brake fluid level can be checked with a
quick glance.

218 Check ing and filling
Di sconnect ing the batt ery terminal s
Some vehicle functions (power window regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng period s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main­
tains starting capab ility over a longer period
~ page 182.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment . The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatures drop . This
is because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling only
short d istances . Let you r authorized Audi
dealer check the capacity of the vehicle bat­
tery before winte r sets in
~ page 219. A well
charged battery w ill not only prevent starting
prob lems when the weather is cold, but wi ll
a lso last longer .
(D Tips
If your vehicle is left standing for severa l
weeks at extremely low temperat ures, the
veh icle battery should be removed and
stored where it will not freeze. This w ill
prevent it from being damaged and hav ing
to be replaced.
Working on the battery
Be especially careful when working on or near
the battery.
The battery is located in the luggage compart­ ment under the floor. Before you check any­
th ing in the luggage compartment,

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.
- 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!
Checking and filling 219
- 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
(ooc).
- 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 .
