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 .

fluid re se rv o ir
Before you c heck a nythi ng in the eng ine compartment ,
always read and heed all WARNINGS~ & in "Working in
the e ngi ne comp art ment" on
page 279.
- Read t he bra ke flu id level from the bra ke fluid reservoir
~ page 289, fig . 212. The brake flu id level must be
between the " MIN" and " MAX" mar kings.
The brake fluid reservoir is locate d at the rear pa rtition of the engine
compartmen t on the left s ide=>
page 280 .
The f luid leve l may drop slightly after some time d ue to the auto ­
m atic a dju stment of t he b rake pads. This is not c ause for ala rm.
If the brake flu id level falls
considerably be low the "M IN" mark, the
brake warni ng/ind icator light (U .S. models :
BRAKE, Canadia n mo dels:
(0) ) will come on=> page 18 and=> page 26. Do not continue to
operate t he vehicle. The complete brake system sho uld be thoroug hly
chec ked by an au thor ized A ud i d eale r or othe r qualified fac ility and
the cause corrected.
If the brake fluid level is too low, the brake
Vehicle OP-eration
warning/ind icator light will illum inate . Contact an au thoriz ed Aud i
de aler
immediately .•
Changing brake fluid
H av e the b rake fluid chang ed by an expe rie nc ed t echni ­
CJ an.
B ra ke flui d abso rb s moi stur e from the air. If the wa te r c on ten t in t he
brake fl uid is too high, corros ion in the b rake system may res ult after
a pe riod of time. The boili ng po int of the brak e flu id will also decrea se
co nsiderab ly and decrease brak ing perfo rmance.
Th erefore, the brake f lui d m ust be c hanged
every two years . Always
use new brake fluid w hich conforms to Fede ral Motor Veh icle Stan ­
dard "F MVSS 1 16 DOT 4" .
Th e br ake f luid reserv oir can be diffi cult to rea ch, there fore, we
recommend that you have the brake fluid changed by your authori zed
Audi dealer . Your deal er h as th e correc t tools, the rig ht bra ke flui d
and the know-how to do th is for you.
& WARNING
• Brake fluid is poisonous. It must be stored only in the closed
original container out of the rea ch of children!
• Brake
failure can result from old or inappropriate brake fluid .
Observe these precaution s:
- Use only b rake fluid that meets SAE specification
J 1703 and
conforms to Federa l Motor Vehicle Standard 116. Alway s check
with you r authorized Audi dealer to make sure you are using
the correct brake fluid. The corre ct type of brake fluid is also
indicated on the brake fluid rese rvoir.
- The brake fluid must be new . Heavy use of the brakes can
c ause a vapor lo ck if the brake fluid is left in the system too
long . Thi s can seriously affect the efficiency of the brakes as
well as your safety. This could result in an accident .

in. WARNING
• To reduce the risk of serious injury and vehicle damage.
-Always lift the vehicle only at the special workshop hoist and
floor jack lift points illustrated=>
page 337, fig. 243 and
=>
page 337, fig. 244.
- Failure to lift the vehicle at these points could cause the
vehicle to tilt or fall from a lift if there is a change in vehicle
weight distribution and balance. This might happen, for
example, when heavy components such as the engine block or
transmission are removed.
• When removing heavy components like these, anchor vehicle
to hoist or add corresponding weights to maintain the center of
gravity. Otherwise, the vehicle might tilt or slip off the hoist,
causing serious personal injury.
0 Note
• Be aware of the following points before lifting the vehicle :
-The vehicle should never be lifted or jacked up from under­
neath the engine oil pan, the transmission housing, the front or
rear axle or the body side members. This could lead to serious
damage.
- To avoid damage to the underbody or chassis frame, a rubber
pad must be inserted between the floor jack and the lift points.
- Before driving over a workshop hoist, check that the vehicle
weight does not exceed the permissible lifting capacity of the hoist.
- Before driving over a workshop hoist, ensure that there is sufficient clearance between the hoist and low parts of the
vehicle. •

page 279.
& WARNING
• Serious personal injury may occur as a result of improperly
performed maintenance, adjustments or repairs.
• Always be extremely careful when working on the vehicle.
Always follow commonly accepted safety practices and general
common sense . Never risk personal injury .
• Do not attempt any of the maintenance, checks or repairs
described on the following pages if you are not fully familiar with
these or other procedures with respect to the vehicle, or are uncer­
tain how to proceed.
• Do not do any work without the proper tools and equipment .
Have the necessary work done by your authorized Audi dealer or
another properly equipped and qualified workshop .
• The engine compartment of any motor vehicle is a potentially
hazardous area. Never reach into the area around or touch the
radiator fan. It is temperature controlled and can switch on
suddenly -even when the engine is off and the ignition key has
been removed. The radiator fan switches on automatically when
the coolant reaches a certain temperature and will continue to run until the coolant temperature drops. ..
