Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 204 Eng ine compartment: cover on the coolant
expa nsion tank
Before you check anything in the engine com­
partment,
a lwa ys re ad and h eed a ll WA RN­
INGS o .A in Working in the engine compart­
ment on page 231 .
Park your vehicle on a level surface.
• Switch
off the ignition .
• Read the engine coolant leve l from the cool­
ant expansion tank
o fig. 204, o page 233.
With a cold engine, the coolant level should
be betwee n the "min" and "max" markings.
When the engine is warm, the level may be slightly above the "max" marking .
The location of the coolant expans ion tank
can be seen in the engine compartment illus ­
tration
o page 233.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in your vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System
o page 16 wi ll
illuminate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level sensor, we
still recommend you check the coolant level
from time to time.
Coolant l oss
Coolant loss may indicate a le ak in the cooling
system. In the event of coolant loss, the cool- ing system shou
ld be inspected immediately
by your authorized Audi dea ler . It is not
enough mere ly to add coo lant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a res ult of overheating.
A WARNING
-The cooling system is under pressure and
can get very hot. Red uce the risk of scald­
i ng from hot coolant by fo llow ing these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping flu id and steam by covering the
cap with a large, th ick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise d irect ion while ap­
plying light, downward pressure on the
top of the cap.
- To avo id being burned, do not sp ill anti­
freeze or coolant on the exhaust system
or hot engine parts. Under certa in cond i­
tions, the ethylene glycol in engine cool­
ant can catch fire.
0 Note
Do not add any type of radiator leak seal­
ant to your veh icle's engine coolant . Add­
i ng radiator repa ir fluid may adverse ly af­
fect the funct io n and performance of your
cooling system and could result in damage not covered by your New Vehicle Limited
Warranty.
Adding coolant
Be very careful when adding engine coolant .
Before you check anyth ing in the eng ine com­
partment,
alw ay s re ad and h eed all WARN­
IN GS o .A in Working in the engine compart­
ment on page 231.
• Tu rnoff the engi ne.
• Let the eng ine cool down.

~ Add coolant mixed in the correct ratio
¢ page 239, Coolant.
~ Tw ist the cap on again tightly .
Replacement engine coolant must conform to
exact specifications ¢
page 239, Coolant .
We recommend using on ly coolant additive
G12 ++, G 13 or in an emergency G12 +. Do
not
use a different additive. In an emergency use
pla in water until you can get the correct addi­
tive and can restore the correct ratio. This
should be done as soon as possible .
If you have lost a considerable amount of
coolant, then you should add co ld antifree ze
and cold water only when the eng ine is co ld.
A lways use
new engine coolant when ref illing.
D o not fill coolan t above the "M AX " mar k. Ex­
cess coolan t will be forced ou t th rough the

gine becomes hot .
&_ WARNING
- The coo ling system is under press ure and
can get very hot. Reduce the risk of
sca ld ing from hot coolant by f ollowing
these steps .
-Tu rn off the engine and a llow i tto cool
down.
- P rotec t your f ace, hands an d ar ms from

app ly ing light, downwa rd p ress ure on
the top of the cap.
- To avo id being burned, do not sp ill an­
tifreeze or coolant on the exhaust sys ­
tem or hot engine parts . Under certa in
conditions, the ethylene glyco l in en­
g ine coolant can catc h fire.
- Antifreeze is poisonous. Always store an­
t ifreeze in its or iginal container and well

Radiator fan
The radiator fan switches on automatically by
itself .
The rad iator fan is dr iven by the engine via the
V-belt. The viscous clutch regulates the speed
of the fan acco rding to the temperature of the
coolant .

of people and the amount of luggage into ac­
count when adjusting tire pressure for a trip -
even one that you would not consider to be
"long." See
c> page 256 , Tires and vehicle
load limits
for more important information.
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres­
sures . Check all of the tires and be sure not to
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your vehicle as listed on the on
your vehicle and in this manual and the kind
of driving you plan to do.
Never exceed the maximum inflation pres­
sure listed on the tire sidewall for any rea­
son.
Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the tires on your vehicle.
It is important to check the tire pressure when
the tires are cold.
- Read the required tire pressure from the tire
pressure label. The tire pressure label is lo­
cated on the driver's side 8-pillar.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reinstall the valve stem cap on the valve .
Tires and wheels 255
When should I check the tire pressure?
The correct tire pressure is especially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a journey. Do not
forget to check the tire pressure for the spare
wheel
c::;,page 271.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
carrying. After changing a wheel
or replacing
wheels you have to adjust the tire pressures on all wheels. In addition, you must then
store the new tire pressures in the tire pres­
sure monitoring system*
c::;, page 266 .
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
[I] appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla­
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fail­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat­
ed on a sticker on the driver's side B-pil­
lar.
- Only when all tires on the vehicle are fil­ led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rectly .
- The use of incorrect tire pressure values
can lead to accidents or other damage .
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned out bulbs for you .
It is becoming increasingly more and more
difficult to replace vehicle light bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the
bu lb . Thi s applies especially to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, and parts
must be correctly taken apart and then prop­
erly put back together to help prevent break­
age of parts and long term damage from wa­
ter that can enter housings that have not been
properly resealed.
F or your safety, we recommend that you have
your authorized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Gas discharge lamps (Xenon lights):
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
Headlights with Xenon light can be ident ified
by the high voltage sticke r.
LE D headlights* require no ma intenance .
Please contact your authorized Aud i dealer if a
bu lb needs to be replaced.
A WARNING
Contact with high-voltage components of
the electrical system and improper re­
placement of gas discharge (Xenon) head­
light bulbs can cause ser ious personal in­
jury and death.
- Xenon bulbs are pressur ized and can ex­
p lode when being changed.
- Changing Xenon lamps requ ires the spe­
cial tra ining, instructions and equip­
ment.
- Only an authorized Audi dealer or other
qualified workshop should change the
bu lbs in gas discharge lamps .
A WARNING
There are parts with sharp edges on the
openings and on the bulb holders that can
cause serious cuts.
- If you are uncertain about what to do,
have the work performed by an author­
ized Audi dealer or other qualified work ­
shop. Serious personal injury may result
from improperly performed work.
(D Tips
-If you must replace the light bulbs your­
self, a lways remember that the engine
compartment of any vehicle is a hazard­
ous area to work in. Always read and
heed all WARNINGS
c> page 231.
-It is best to ask your authorized Audi
dealer whenever you need to change a
bulb.
