Before you c hec k anythi ng in the engine compartment,
alwa ys r ead and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 277.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank==>
page 284, fig. 211. With a cold engine, the
coolant level should be between the "min" and "max"
markings . When the engine is wa rm, the level may be
sligh tly above the "max" marking .
The locat io n of the coolant expansion tank can be seen in the engine
compartment ill ustration ~
page 278.
To obta in an accurate reading, the engine must be sw itched off.
The expans ion tank in your vehicle is equ ipped with an electric coolant
level sensor .
When the coolan t level
is too low, the warn ing light in t he Au to-Che ck
System ~
page 2 7 will blink until you add coo lant and the level has
bee n restored to normal. Even though the re is an elect ric coolan t
level sensor, we still recommend you check the coolant leve l from
time to time .
Coolant loss
Coolant loss may ind icate a leak in the cooling system. I n the event of
coo lant loss, the cooling system should be inspected immed iately by
yo ur au tho rized A ud i dea le r.
It is not enough mere ly to add coolant.
In a
s e a le d system, losses can occur only if the bo iling point of the
coo lant is exceeded as a resu lt of overheating .
0 Note
Do not add any type of radiator leak sealant to your vehicle's engine
coo lant. Add ing radiator repa ir fluid may adverse ly affect the func­
tion and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warra nty. •
Safety first
Adding coolant
Be very careful when adding engine coolant.
B efore you check a nything in t he engine compartment,
always read and heed all WARNINGS==> & in "Working in
the engine compartment" on
page 2 77.
- Turn off the engine.
- Let the engine cool down .
- Place a th ick rag over the coolant expansion tank
==>
page 284 , fig. 211 and carefully twist t he cap counter­
clockw ise ==>& .
- Add coolant .
- Twist the cap on again
tightly .
Replacement eng ine coolant must conform to exact spec ifications
~ page 284, "Coolant". Even in an emergency, if coolant additive
G 12++, G12+ or G12 is not available, do
not use a different addi tive .
Use plain water instead until you can get the correct additive and can
restore the correc t ratio. This should be done as soon as possible.
If you have lost a considerable amount of coolant, then you should
add co ld antifreeze and cold water only when the eng ine is co ld .
Always use
new engine coo lant w hen refilling.
Do not fill coolant above the "MAX" mark. Excess coolant will be
forced ou t th rough the p ress ure relief v alve in the cap when the
engine becomes hot .
& WARNING
• The cooling sy stem i s under pres su re a nd can get very hot.
Reduc e the ri sk of scalding from hot coolant by following the se
steps.
-Tu rn off the engine and allow it to co ol d own . _,.

General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least appreciated and most abused pa rts of a motor
vehicle . Tires are, however, one of the most important parts of a
vehicle , pa rticul arly conside ring the comparat ive ly small patch of
rubber on eac h tire that assures that all-important contact between
you, your veh icle and the road.
Maintai ning t he cor rect tire pressu re, mak ing su re that your veh icle
and i ts tires do not have to carry more weight t han they can safely
hand le, avoid ing damage from road ha za rds and regularly inspecting
tires for damage includ ing cuts, s lashes irregular wea r and ove rall
condi tion a re the mos t important th ings that you can do to help avoid
sudden t ire failure including tread separation and blowouts.
Avoiding damage
If you have to d rive ove r a cur b or sim ilar obstacle, d rive very slowly
and as close as possible at a rig ht angle to the curb .
Always keep chemicals incl ud ing grease, oil, gaso line and brake f luid
o ff t he t ires .
Ins pect the ti res regularly for damage (cu ts, cracks o r blisters, e tc.) .
Remove any foreign bodies embe dded in the treads.
Storing tires
M ark tires w hen yo u remove t hem to indica te t he d ire ct io n of rota ­
tion . This ensures you to be ab le to mount them correctly when you
re insta ll them.
Whe n removed, t he wheels or tires should be sto red in a cool, dry and
preferably da rk p lace.
Safety first
Store tires in a v ertica l pos it io n if they a re not mount ed on rims, in a
hor izonta l posit ion if they are mounted on r ims.
New tires
N ew tires have to be broken in=> & .

Hidden damage
Damage to tires and rims is often not readi ly visible. If yo u notice
unu sual vib ra ti on o r the ve hicle pulls to one side, t his may in dica te
that one of the t ires has been damaged. The tires must be checked
im media tely by an auth oriz ed A ud i d eale r or qual ifie d wor ks hop.
Unidirectional tires
A un id irectional tire can be identified by arrows o n th e sidewall , th at
point in the direct ion the t ire is designed to rotate. You must fo llow

& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, dri ve with special care for the first 350 miles (560 km).
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately. _..

Tire pressure generally refers to t he amo unt of a ir i n a tire tha t it
needs it to do its job and safe ly carry the comb ined load of t he entire
vehicle and its contents . Tire p ressure is measured in kilopasca ls
(kPa), the inte rnationa l measur ing unit and in poun ds per squar e in ch
(PSI). Tire press ure is based in part on the ve hicle 's design and load
limit -the greatest a mount of weight that the vehi cle can c arry safe ly
and the tire s ize. The proper tire pressure is frequently refer red to as
the "re commen ded cold t ire inflation p ressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use. T he tire press ure is hig her w hen the tir e h as warme d up
than whe n it is "cold." It is the inflation pressure in a "cold" tire that
c o unts. The refo re, you sho uld never let air o ut of a warm t ire to
match "cold ti re inflation pressure " recommendations . The t ires
wou ld then be under in flated and could fail s uddenly.

_& WARNING
Overloading a vehicle can cause loss of vehicle control , a cra sh or
other accident, serious personal injury, and even death .
• Carrying more weight than your vehicle wa s de signed to carr y
will prevent the veh icle from handling properly and increase the
risk of a los s of vehicle control.
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe di stan ce.
• Tires on a vehicle that has been overloaded can fail suddenly
c ausing lo ss of control and a crash .
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
