't:::7: Engine oil pressure
The red en gine oil pressure warning symbol
requires immediate service or repair . Driving
with a low-oil -pressure indication is likely to
inflict severe damag e to the engine.
• Turn off engine! Oil pressure too low
If th e ind ic a tor lig ht tur ns on and th e me s­
sage a ppears, the oil press ure is too low .
~ Pull off the road.
~ Sto p th e ve hicl e.
~T urno ff th e e ngine.
~ Check the engine oil level ¢ page 211.
~ If the engine oi l leve l is too low , add engine

~ If the en gine o il level is co rrec t and the in di­
cato r light still turns on, turn the e ngine
off
and do not cont inue driv ing . See k pr ofessi o­
na l assistance .
(D Tips
- The engine oil pressure symbol. is
not an indicator for a low engine oil lev­
el. Do not rely on it. Instead, check the
oil level in your engine at regular inter­
vals, preferably each time you refuel,
and always before going on a long trip.
- The yellow oil level warning indication
Ill requires oil refill or workshop serv­
ice without delay . Do not wait until the
red oil pressure warning. starts to
flash before you respond to the low oil level warning
Ill. By then, your engine
may already have suffered serious dam­
age.

pedal and move th e se lector lever to the P
or
N position.
• Press the key
c> fig. 74 -the eng ine will
star t.
Sw itching the i gni tion on /off
If you wou ld like to switch the ignition on
without starting the engine, follow these
steps :
• Insert the key into the ignition lock .
• Press the key briefly
with out pressing the
c lutch pedal (for man ua l transmissions) or
the brake peda l (for automatic transmis­
s ions) .
• To switch the igni tion off, press the key
again .
When starting the engine, ma jor e lectr ica l
loads are swi tched off temporarily .
You can on ly remove the key with the ignition
switched off.
I f the engine should not sta rt immed ia tely,
the starting process is automatically stopped
after a short time. Repeat starting procedure .
A WARNING
-Never allow the engine to run in confined
spaces -danger of asphyxiation .
- Never remove the ign ition key from the
ignition look whi le the vehicle is moving.
Otherw ise, the steering lock could sud­
denly engage and you would not be able
to steer the vehicle.
- Always take the key with you whenever
you leave your vehicle . Otherwise, the
engine could be started or electr ica l
equipment such as the power w indows
c ou ld be operated. This can lead to seri­
o us inj ury.
- Never leave children or persons requiring
assistan ce u nattended in the vehicle . The
doors c an be lo cked using the remo te
transmitter, preventing people from es­
caping from the vehicle o n their own in
the event of an eme rgency. Depending
on the time of year, people inside the ve- h
icle can be exposed to very high or very
low temperatu res.
@ Note
Avoid high eng ine rpm, f ull throttle and
heavy engine loads unti l the engine has
r eached operating tempe rat ure -other­
wise you risk eng ine damage.
@ For the sake of the environment
Do not let the engine run w hile parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions.
(D Tips
- If the key cannot be removed from the
ignition lock, you have to pull the me­
chanical key out of the master key in or­
der to be able to lock the vehi-
cle <=>
page 35 .
-After starting a cold engine, there may
be a brief period of increased noise be­
cause the oil pressure must first bu ild up
in the hydraulic valve ad justers. This is
normal and not a cause for concern.
- If you leave the veh icle with the ignition
switched on, the ignit ion w ill switch off
afte r a certain per iod of t ime . P lease
no te that electrical eq uipment such as
exterior ligh ts will sw itch off as well
when that happens .

7 4 On the road
(D Note
If the engine has been under heavy load
for an extended period, heat builds up in
the engine compartment after the engine
is switched off -there is a risk of damaging
the engine . Allow the engine to run at idle
for about two minutes before switching it
off.

afte r a short t ime. Repeat start ing procedure.
When sta rting the engine, major elect rical
loads are switched off temporar ily .
After a cold engine is started, there may be a
brief period of increased noise because oil
pressure must first build up in the hydrau lic
valve adjusters . This is norma l and not a cause
for concern .
.&_ WARNING
-
-Never allow the engine to run in confined
spaces -danger of asphyxiation.
- Never turn off the engine until the vehi­
cle has come to a complete stop.
- Always take the key with you whenever
you leave your veh icle . Otherw ise, the
engine could be started or electrical
equ ipment such as the power windows
could be operated . This can lead to seri­
ous injury .
- Never leave children or persons requiring
assistance unattended in the vehicle . The
doors can be locked using the remote
tr an smitter, preventing people from es­
caping from the veh icle on their own in
the event of an emergency. Depending
on the time of year, peop le inside the ve­
hicle can be exposed to very high or very
low temperatures .
(D Note
-Avo id high engine rpm, full throttle and
heavy eng ine loads until the engine has
reached operating temperature -other­
wise you risk engine damage.
@ For the sake of the environment
Do not let the engine run while parked to
warm up. Begin driving immediately. This
reduces unnecessary emissions .
(D Tips
-After starting a cold engine, there may
be a brief period of increased noise be-
cause the oil pressure must first build up .,.

184 Intelligent technology
At higher speeds and with the windshield wip ­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals without the
driver noticing and provides for better brake
response time under wet condit ions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likew ise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
plications of the brake¢&. .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with l ittle use of the
brakes .
If the brakes are not used frequently , or if cor­
rosion has formed on the discs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢,& .
Fa ults in the brake system
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢&. .
Low brake fluid le vel
Malfunct ions can occur in the brake system if
the brake fluid level is too low. The brake fluid
leve l is monitored electronically .
Brake boost er
The brake booster increases the pressure that
you generate w ith the brake pedal. It works
only when the eng ine is running .¢ &.
Brake lining w ear status
Brake lining wea r may be checked by vis ual in ­
spection of the condition of the brake pads
through the openings in the whee l. If neces­
sary, the whee l may be removed for this in ­
spection
¢ page 244, Changing a wheel.
_& WARNING
-New brake pads don't have the best stop­
ping power and must be "broken -in" dur­
ing the initial 100 to 150 miles (150 to
200 kilometers) of normal c ity driving .
You can compensate for this by pressing the brake pedal more firmly . T his also
applies later when new pads are instal­ led.
- You shou ld perform braking maneuvers
for the purpose of cleaning the brake system only if road conditions permit .
Othe r road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long o r too often . This could cause the
brakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing you r
foot on the pedal when you do not intend
to b rake. This may cause the brakes to
overheat, p remature wear and increased
s topping distance.
- Unde r ce rtain cl imatic and ope rat ing
conditions such as passing thro ugh wa ­
ter, dr iving in heavy rain o r after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
d iscs and drums. Carefully apply brakes
for a test. Brakes will dry and ice coat­
ings will be cleaned
off after a few care­
fu l brake applicat ions .
- Driving for an extended period of t ime on
salt-covered roads without using your brakes can a lso affect braking efficiency .
Clean
off accumulated salt coating from
b rake discs and pads wi th a few ca reful
b rake applications.
- I f you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
flow to the front brakes is not obstruct-
ed . Otherwise the brake system could

"MAX" markings. When the engine is warm,
the leve l may be slightly above the "MAX"
marking .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
c:> page 208.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in you r 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
c:> page 17will
b link until you add coo lant and the level has
been restored to no rma l. Even though there is
an electric coolant level sensor, we still rec ­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in t he cool ing
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized A udi dealer.
It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is unde r pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps .
- Turn
off the engine and allow it to cool
dow n.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag .
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap .
- To avoid be ing burned, do not spill ant i­
freeze or coolant on the exhaust system
'
or hot engine parts. Under certa in cond i­
tions, the ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not a dd any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add ­
i ng radiator repa ir fl uid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty .
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com­
partment,
always read and heed all WARN­

driving a few yards and correct if neces­
sary . Follow the instructions from the
snow cha in manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer ­
tain roads, this norma lly also applies to
veh icles with all wheel drive .
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design o f whee l bolts is matched to the
factory insta lled r ims . If different rims are fit ­
ted, the correct wheel bo lts wit h the right
l ength and correctly shaped bolt heads must
be used. This ensures that wheels are f itted
securely and that the brake system functions
correctly .
In certain circumstances, you may not use
wheel bo lts from a different vehicle -even if it
is the same model<=>
page 266.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
cont ro l, a co llision and serious persona l in­
Jury .
- Always keep the w heel bolts and the
threads in the wheel hubs clea n so the
w hee l bolts can t urn easily and be p rop­
erly t igh tened.
- Never grease or oil the wheel bolts and
the threads in the wheel h ubs. They can
become loose wh ile d riving if greased or
oiled, even if tightened to the specified
torq ue.
- Only use whee l bo lts that belong to the
rim being installed .
- Never use different whee ls bolts on your
vehicle.
- Alw ays m ain ta in the co rrec t tig hten ing
torq ue fo r the wheel bo lts to reduce the
risk of a wheel loss . If the tightening tor­
que of the wheel bo lts is too low, they
can loosen and come out when the vehi-
Tire s an d wheel s 239
cle is mov ing. If the tightening torq ue is
too high, the wheel bolts and threads
can be damaged and the whee l can be­
come loose.
@ Note
The specified torque for the whee l bolts is
90 ft lbs . (120 Nm) w ith a tolerance of
± 7,4 ft lbs. (± 10 Nm). Torque whee l bolts
diagonally . After changi ng a wheel, the
torque m ust be checked as soon as poss i­
ble with a to rque wrench -preferably by an
a uthorized Aud i dea le r or qualified wor k­
shop .
Low aspect ratio tires
Your A udi is fac tory -eq uipped w ith low aspect
ratio tires . These tires have been tho ro ughly
tested and been se lected specifically for your
model for their superb performance, road fee l
and handling under a variety of driving condi­
tions . Ask your authorized Aud i 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 represents the ratio
of the tire's sidewa ll height in relation to its
tread width exp ressed in percentage. Conven­
tiona l tires have a he ight/w idth ratio of 60 or
more.
The performance of low-a spect-r atio tire s is
particularly sensit ive to improper inflation
pre ssure. It is therefor e important that low
a spect ratio tire s are inflated to the specified
pres sure and that th e inflation pr essure i s
regularly checked and maintained. Tire pre s­
sure s should be chec ked at lea st once a
month and always before a long trip
<=> page 228 , Checking tire pressure.
What you can do to avo id tire and rim
damage
Low aspect ratio tires can be damaged mo re
easily by impact w ith potholes, curbs, gull ies
or ridges on the road, particularly if the tire is
under inflated . ..,.
