2015 AUDI S3 checking oil

226 Checking and Fill in g
- Do not add any type of radiator leak sea l­
ant to your ve hicle's engine coolant.
Adding rad iator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in damage not covered by your New Vehicle
Limited Warranty.
Adding coolant
Fig . 164 Engine co mpa rtment: mark in gs on the coo l­
ant expans ion tank
R ea d a nd f ollow ing th e W ARNING S before
checking anything in the eng ine compartment
¢ page 217.
Ch eck ing t he e ngi ne coolant level
"Park your vehicle on a level surface .
.. Switch the ign ition off .
" Read the coo lant level on the coolant expan­
s ion tank ¢
fig. 164. The coo lant level must
be between the markings when the eng ine
in cold. When the engine is warm it can be
sl ightly above the upper marking .
Adding coolan t
Requirement : There must be a residual
amount of coolant in the expansion tank ¢(D .
.. Let the engine cool down.
" Place a cloth over the coolant expansion
tank cap and unscrew the cap counterclock­
wise ¢&_ .
.. Add coolant mixed in the correct ratio
¢ page 225 up to the upper marking.
.. Make sure that the fluid level remains sta­
ble. Add more coolant if necessary.
" Clove the cap securely. A coolant loss suggests a
leak. Immediately
drive your vehicle to an authorized repair fa­
c ility and have the cooling system inspected.
If the cooling system is not leaking, a loss can
come from the coolant boiling through over­
heating and being pushed out of the cooling
system.
A WARNING
The cooling system is press urized and can
become very hot. To reduce the r isk of
b urns from hot coolant:
- Do not open the coolant expansion tank
cap with the engine ho t. T here is a risk of
burns.
- Stop the eng ine and a llow it to cool.
- Protect your face, hands and arms from
escaping coolant and steam by covering
the coolant tan k cap with a large, th ick
cloth.
- Turn the coolan t tank cap counterclock­
wise slowly and keep light pressure on
the cap .
- To reduce the risk of burns, do not allow
any antifreeze or coolant to drip onto the
exhaust system or hot engine compo ­
nents. The ethy lene g lycol in engine
coo lant can catch fire under certain cir­
cumstances.
- The coolant additive and the coolant can
be dangerous to your health . For this
reason, keep the coo lant in the origina l
container away from ch ildren . There is a
risk of poisoning.
- When working in the engine compart­
ment, remember that the rad iator fan
can switch on even if the ignition is
sw itched off, which increases the risk of
pe rsonal injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system
and damage the eng ine .
If this is the case,
do no t continue dr iving. See a n author ized
A udi dealer or authori zed Aud i Service Fa­
cility for assist ance.

Radiator fan
The radiator fan switches on automatically by
itself
An auxiliary electric radiator fan switches on
and off depending on coolan t temperature
and other vehicle operating conditions .
After you switch the engine off, the auxiliary
fan can continue running for up to 10 minutes
- even with the ignition off. It can even switch
on again later by itself<=>.& , if
- the temperature of the engine coolant rises
due to the heat build-up from the engine in
the engine compartment, or
- the engine compartment heats up because
the vehicle is parked in intense sunlight.
A WARNING
-To reduce the risk of personal injury nev­
er touch the radiator fan.
- The auxiliary electric fan is temperature
controlled and can switch on suddenly
even when the engine is not running.
- The auxiliary radiator fan switches on au­
tomatically when the engine coolant
reaches a certain temperature and will
continue to run until the coolant temper­
ature drops.

Fig. 165 Engine compa rtment: cove r on the brake fluid
rese rvoir
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS r::;, page 217 .
Checking and Filling 22 7
.. Read the brake fluid level from the brake
fluid reservoir <=>
fig. 165, <=> page 220,
fig. 159.
T he brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake fluid reservoir can be seen in the engine compartment illustration
<=>page 220.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)
I. (Canadian
models) will come on
c:> page 18 . Do not con­
tinue to operate the vehicle. The complete
brake system should be thoroughly checked
by an authorized Audi dealer or other quali­
fied facility and the cause corrected . If the
brake fluid level is too low, the brake warning/
indicator light will illuminate. Contact an au­
thorized Audi dealer
immediately.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician.
Brake fluid absorbs moisture from the air . If
the water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time. The boiling point of the
brake fluid will also decrease considerably and
decrease braking performance.
Therefore, the brake fluid must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.

In certain circumstances, you may not use
wheel bo lts from a different vehicle -
even if it
i s the same mode l
Q page 291.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose caus ing loss of
control, a collision and ser ious personal in­
jury .
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly t ightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose w hile d riving if greased or
o iled,
even if tightened to the spec ified
torq ue.
- Only use wheel bo lts that belong to the
rim being ins talled.
- Never use different whee ls bolts on your
vehicle .
- Always maintain the correct tightening
torque fo r the wheel bolts to reduce the
risk of a wheel loss. If the tigh teni ng tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving . If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel ca n be­
come loose .
(D Note
The specified torque for the wheel bo lts is
90 ft lb (120 Nm) w ith a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a wheel, the
torque must be checked as soon as possi­
b le with a torque wrench -prefe rably by an
author ized Audi dealer or qualified wo rk­
shop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires . These tires have been thorough ly
tested and been selected spec ifically for your
model for the ir superb performance, road feel
Tire s an d wheel s 263
and handling under a variety o f driving condi ­
tions. Ask your authorized A udi dealer for
more details .
T he low aspec t ratio of these tires is ind icate d
by a numera l of
55 or le ss in the tire's size
designation. The numera l represents the ratio
of the t ire's sidewa ll height in relation to its
tread width expressed in percentage.
Conven­
tiona l tires have a he ight/w idth rat io of 60 or
more .
The performance of low-a spect-ratio tire s is
particularl y sens it iv e to improper inflation
pressure. It is therefore important that low
a spect ratio tir es are inflated to the specified
pre ssure and that the inflation pr essure i s
regularly checked and ma intain ed . Tire pr es­
s ure s should be checked at lea st on ce a
month and alway s bef ore a long trip
~ page 245 , Checking tire pressure .
A Word about Low Aspect Ratio and High
Performance Ti res
Hig h pe rformance tires are des igned for bet­
ter performance and handling in warm cli­
mates. When driving in cold, snowy or icy
weather, you sho uld equ ip your vehicle w it h
four all-season or winter tires, which
offer
better traction under those condit ions. We
suggest you use the Audi recommended win­
te r or a ll-season tires specified for you r Audi.
High performance tires a lso have a lower as ­
pect ratio that aids performance and han­
dling . Driving over rough or damaged road
surfaces, as well as debr is, cu rbs and other
obstacles can cause serious damage to
whee ls, tires, vehicle body, and suspens ion
parts . B e carefu l to avo id road hazards and re­
du ce your speed , espec ia lly if your vehicle is
equipped wi th low prof ile tires .
Please a lso remember when making your se­
lection that, wh ile these tires deliver respon­
s ive handling, t hey m ay ride less comfo rtably
and make more noise than o thers . Finally,
these tires may wear more quickly than other
c h oices.
