If the needle is well in the upper area of the gauge, the coolant
tempe rat ure is too high.
Stop the vehicle , switch the engine off and
allow the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Alway s observe th e warning in => page 271, "Engine comp art ­
ment ", before opening the hood and checking the engine coolant
level.
• Never open the engine hood if you see or hear steam, or if you
s ee engin e coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­
t ur es o r high engine load, the engine could overheat.
• The front spo iler has bee n des igned to prope rly d istribute the
coo ling air when the vehicle is moving.
If the spoiler is damaged, this
cou ld reduce the coo ling effect and the eng ine could then overheat .
Ask your author ized A udi dealer for assistance .•

Under certain circumstances, weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the underside of the vehicle shou ld be thoroughly
washed, p referably in a profess ional car wash.
& WARNING
Always read and heed all WARNINGS and other information
~page 260. •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
Th e vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash . However, the
effect on the paint depends to a lar ge exten t on the design of the
facility, the filtering of the wash water, the type of wash and care material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash.
Before going thro ugh a car wash, be sure to take the usual precau­
tions such as closing the windows and power roof. Factory installed
antennas must not be removed.
If you have installed additional accessories on the vehicle -such as
spoilers, roof rack, etc. - it is best to ask the car wash operator if these
should be removed.
& WARNING
Always read and heed all WARNINGS and other information

General
We offe r m any di fferen t types o f lea ther on ou r ve hicl es. Most are
differen t types of nappa leat her, which has a smooth s urface and
comes in va rious co lo rs .

consider if childre n, animals or other factors might prove to be partic­
ularly hard on the leathe r.
By contrast, leather types that are covered by a colored fin ish layer
are more durable . This has a positive effect on the leath er's resistance
to wear and so iling in daily use. On the othe r hand, the typical charac­
teristics of natura l leathe r are barely or not apparent . However, this
does not mean that the leathe r itself is of infer io r quality.
C are and handling
Because of the exclusive nature of the types of leather that Audi uses
and the ir unique p roperties (such as sensitivity to oils, grease, so iling,
etc.), yo u will need to be somewhat ca refu l with these leat he rs , a nd
a certain type of care is required. For example, dark clothing mate­
r ials ca n disco lor leather seats (especially if such clothi ng is d amp and
was not dyed correctly) . Dust and dirt particles in pores, folds, and
seams can have an abrasive effect and c an damage the le athe r
surface as well as weaken seams .
The leather s houl d be cleaned regularly as needed . After having been
used for a relatively long time, your leather sea ts w ill acquire a rich
aged finis h. This is a characteristic of natura l leather and a sign of
true quality.
I n order to maintain the value of this natural product over the life of
your vehicle, you sho uld fo llow the recommendations below :
0 Note
• To keep you r leather from b leaching out, do not allow it to be
exposed to bright sunl ight for long periods of time . If you have to
leave t he veh icle parked outside for long pe riods, cover the leather to
protect it from direct exposure to sunlig ht.
• Sharp objects on clothing, such as zippers, rivets or sha rp pieces
on belts can leave permanent scratches or scrape marks on the
s u rface of the leather.
Safety first
(I] Tips
• After each time you clean the leathe r and at regular inte rvals , u se
a leather preservative creme that contains UV-blockers and that
works into the leather. This creme will nou rish and mo istur ize the
leather, helping it to breathe and stay supp le. It also helps to build up
a p ro tect ive coa ting on the surfa ce.
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc. as soon as poss ible.
• Preserve the color of t he leather as needed by using a specia l
co lored leather ca re creme to touch up areas of uneven color .•

Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
- Clean so iled areas wit h a slightly mois tened cotton or
woolen cloth .
More stubborn dirt
-More stubborn d irt can be removed using a clot h satu­
rated w ith a mild soap solution (2 ta blespoons m ild liq ui d

- Never allow the soap solution to saturate the leather, and
make certa in that no water soaks i nto the seams .
- Wipe off the soap solution w ith a soft, dry c loth. .,,

Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from o ve rheat ing and it prote cts the engine from
free zing in the winter .
The cooling system is sealed and genera lly requ ires little attention .
Th e cooling system has been fi lled a t the factory w it h a permanent
coo lant which does not need to be changed. The coolant consists of a
mixture of water and the man ufacturer's glycol-basedcoo lant add i­
tive Gl2++ a ntifreeze with ant i corrosion additives (50% for USA
mode ls; 60% for Canadian mode ls). This mixture bot h assures the
necessary frost protec tion and p rotects metal components i n the
engine's cooling system from corrosion and scaling . It a lso ra ises the
boiling point of the coolant.
Do not reduce the concentration of the coolant in the summer by
adding p lai n water . The proport ion of coolant additive must be at
least 50 % but not more than 60 % to maintain ant ifreeze protection
and coo ling efficiency. If the coolant frost protect ion is too low, the
coo lant co uld freeze and damage the veh icle heating and eng ine
cooling system .
For year-ro und d riving, antifreeze is added at t he factory for temper­
atures down to:
• - 31°F( -35°C)USA
• - 40 °F ( -40 °C) Canada .
You can mix the G12 ++ coo lant additive with other add it ives (G12 + or
G 12) . Always check with yo ur a utho rized Aud i dea ler .
& WARNING
Before you check anything in the engine compartment, always
read and heed all WARNINGS=>
& in "Working in the engine
compartment " on
page 279.
0 Note
• Before winter sets in, have the coolant checked to see if the
coo lant additive in you r vehicle is s ufficient to meet the climate
condi tions. This is especially important if you live in a region where
the winter is extreme ly cold. If necessary, increase the proport ion of
c oo lan t add it ive to 60%.
• When adding coolant additive to your cooling system, remember:
- We recommend using only coo lant add it ive G 12++ (check the
label) for your vehicle . This coolant additive is available at autho­
r ized A ud i deale rs. Othe r ty pes of antifreeze can s ignifica ntly
reduce corrosion protection. The resulting corrosion can cause a
loss o f coolant and serious engine damage .
• Do not add any type of radiator leak sealant to you r vehicle's
eng ine coolant. Adding rad iator repair fl uid may adversely affect the
function and performa nce of your coo ling system and could resu lt in
d a mage not covered by your New Vehicle Limi ted W arranty. •
Checking the engine coolant level
The engine coolant level can be checked with a quick
glance .

& WARNING
Sudden tire failure can lead to los s of control, a cra sh and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control.
• Always keep chemicals that can cause t ire damage, such as
grease , oil, gasoline and brake fluid away from tires.
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failu re and loss of vehicle control. •
