with a low-oil-pr essur e indication is likely to
inflict severe damage to the engine.
• Swit ch off engine and ch ec k oil l evel
If the indicator light turns on and the mes­
sage appears, the oil pressure is too low .
., Pull off the road.
., Stop the vehicle.

-Always disconnect the battery.
- Never smoke or work near heaters or open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch :
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V-belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical ha zards c:::> & .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition ,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm .
Checking and filling 225
-Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
(® For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly . If
you see spots from oil or other vehicle flu­ ids, have your vehicle inspected by an au­
thorized Audi dealer.
Closing the engine hood
.,. Pull the hood down until the pressure from
the struts is reduced.
"'Let the hood
drop down and latch in place.
Do not try to push it shut; it may fail to en­
gage
c:::> ,A .
A WARNING
-
A hood that is not completely latched
could fly up and block your view while driv ­
ing .
- When you close the engine hood, check it
to make sure the safety catch has proper­ ly engaged. The hood should be flush
with the surrounding vehicle body parts.
- If you notice while driving that the hood
is not secured properly , stop at once and
close it. •

232 Check ing and filling
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance .
Fig . 191 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 224 .
., Park your vehicle on a level surface.
., Switch
off the ignit io n.
., Read the eng ine coolant level from the cool ­
ant expans ion tank
o fig . 191, o page 226,
fig. 188. With a cold eng ine, the coolant
level should be between the "min" and
"max" markings. When the engine is warm,
the leve l may be slightly above the "max"
marking.
The location of the coolant exp ans ion tank
can be seen in the engine compartment illus­
tration
o page 226.
To obtain an accurate read ing, the engine
must be switched
off.
The expans ion 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 17 will
illum inate unt il you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant loss
Coolant loss may indicate a leak in the cool ing
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 coolant .
In a
sea le d system, losses can occur on ly if
the boiling point of the coo lant is exceeded as
a resu lt 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
fe ct 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 .

partment ,

chains because the vehicle will be ex­
tremely low. If you do drive with snow
chains on while the vehicle is at this lev­
el, the snow chains might severe ly dam­
age the wheelhouse and other parts of
the veh icle .
@ Tips
Where snow cha ins are mandatory oncer­
tain roads, this normally also applies to
veh icles with all -wheel dr ive.
Wheel bolts
Wheel bolts mu st always be tigh tened to the
correc t torque .
The design of whee l bolts is matched to the
factory in sta lled r ims. If different rims are fit ­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used . This ensures that wheels are f itted
secure ly and that the brake system f unctions
correctly .
In certain circumstances, you may not use
wheel bolts from a d iffe rent vehicle -even if it
i s the same mode l
¢page 285.
A WARNING
Imprope rly tig hte ned or maintained whee l
bolts can be come loose causin g loss of
contro l, a co llision and serious persona l in­
jury .
- Alw ays keep the w heel bolts and the
th reads in the wheel hubs clea n so the
wheel bolts can turn easily and be prop­
er ly tightened .
- Never grease or oil the wheel bo lts and
the threads in the w heel h ubs. They can
become loose while driving if greased or
o iled, even if tightened to the specif ied
torque.
- Only use wheel bolts that belong to the rim being installed.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the co rrect tightening
torq ue for the wheel bo lts to reduce the
Tire s an d wheel s 257
risk of a wheel loss. If the tighte ning tor­
que of t he wheel bolts is too low, they
can loosen and come out when the vehi­
cle is mov ing . If the tighte ning torque is
too h igh, the wheel bol ts and threads
can be damaged and the whee l can be­
come loose.
(I) Note
The specified torque for the whee l bolts is
90 ft lb ( 120 Nm) with a tole ranc e of± 7,4
ft lb(± 10 Nm). Torq ue whee l bolts diago­
nally. Afte r cha nging a whee l, the torq ue
must be checked as soon as possible wi th a
torque w rench -prefe rably by an au thor­
i z ed Audi dealer or qualif ied workshop .
Low aspect ratio tires
Your Audi is facto ry-eq uipped with low aspect
ratio tires. These tires have been thoro ughly
tested and been se lected specifically for your
model for their superb performance , road fee l
and handling under a variety of driving cond i­
tions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these t ires is ind icated
by a numeral of
55 or less in the tire's size
designation . The numera l rep resents the ratio
of the t ire's sidewall height in relation to its
t read width ex pressed in perce ntage. Conven ­
tion al tires have a he igh t/w idth ratio of 60 or
more.
The performance of low-aspe ct-ratio tire s is
particularly sensitiv e to improper infla tion
pres sure. It is therefore important that l ow
a spect ratio tires are inflated to the specified
pre ssure and that the inflation pressure is
regularly checked and maintained. Tire pres·
sures should be checked at least once a
month and always before a long trip
¢ page 246, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact w it h potholes , curbs, gul lies ..,.
