warning AUDI S3 SEDAN 2017 Owners Manual

Checking and Filling
CJ) Note
-The engine oil level must not be under the
marking
(D r=> fig. 272, because this increas­
es the risk of engine damage.
- After adding engine oil, the oil level must
not be above the marking
@ c:> fig . 2 72, be­
cause this increases the risk of catalytic con­
verter and/or engine damage. Do not start
the engine. Contact an authorized Audi
dealer or authorized Audi Service Facility to
have excess engine oil extracted if necessa­
ry .
- Do not mix any additional lubricants into
the engine oil. Damage caused by such addi­
tives is not covered by the warranty .
@ For the sake of the environment
-Engine oil should never enter the sewer sys­
tem or come into contact with the ground under any circumstances.
- Pay attention to legal requirements when
disposing of empty oil containers.
@ Tips
The engine oil consumption may be up to
0 .S quart/600 miles (0.5 liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumption may be higher during the
first 3,000 miles (5,000 km). The engine oil
level must be checked regularly. It would be
best to check each time you refuel your vehi­
cle and before long drives.
Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi d eal er or o qualified s ervice sta­
tion.
Before you check anything in the engine compart­
m ent,
always read and heed all WARNINGS
r=> page 316.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance bookl et. This is very important b ecause the
lubric ating properties of oil diminish gradually
during normal vehicle use.
322
Under some circumstances the engine oil should
be changed more frequently. Chang e oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Detergent additives in the oil will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information :
,&. WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
oil , let the engine cool down to the touch.
- When removing the oil drain plug with your
fingers, stay as far away as possible . Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at
least the total amount of oil in your engine.
- Engine oil is poisonous . Keep it well out of
the reach of children.
- Continuous contact with used engine oil is
harmful to your skin . Always protect your
skin by washing oil off thoroughly with soap
and water .
0 Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect your Audi Limited New Vehi­
cle Warranty .

Checking and Filling
When the engine is warm it can be slightly above the upper marking.
Adding coolant
Plug-in hybrid drive* : Your vehicle has two cool­
ant expansion tanks that are separate from each
other. The smaller of the two expansion tanks
must not be opened
¢ page 104. Read and fol­
low the important safety precautions ¢
A in
Coolant on page 105 .
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 counterclockwise
¢_&. .
~ Add coolant mixed in the correct ratio
¢page 323 up to the upper marking.
~ Make sure that the fluid level remains stable.
Add more coolant if necessary.
~ Close the cap securely.
Coolant loss usually indicates there is a leak . Im­
mediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected.
If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheating
and being pushed out of the cooling system.
.,&. WARNING
The cooling system is pressurized and can be­
come very hot. To reduce the risk of burns
from hot coolant:
- Do not open the coolant expansion tank cap
when the engine is hot. This increases the
risk of burns.
- Stop the engine and allow it to cool.
- Protect your face, hands and arms from es-
caping coolant and steam by covering the
coolant tank cap with a large, thick cloth.
- Turn the coolant tank cap counterclockwise
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 ex­
haust system or hot engine components.
324
The ethylene glycol in engine coolant can
catch fire under certain circumstances.
- The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children . There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty . Air could enter the cooling system and
damage the engine . If this is the case, do not
continue driving . See an authorized Audi deal­
er or authorized Audi Service Facility for assis­
tance.
- Before the start of winter, have an author­
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.
- If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en­
gine. If this happens, only use water and re­
store the correct mixture ratio with the
specified coolant additive as soon as possi­
ble .
- Only refill with new coolant.
- Radiator sealant must not be mixed with the coolant.
· Radiator fan
The radiator fan switches on automatically by it­
self
An auxiliary electric radiator fan switches on and
off depending on coolant 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 r ises due
to the heat bui ld-up from the engine in the en­
gine compartment , or
- the engine compartment heats up because the
vehicle is parked in intense su nlight .
_& WARNING
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary elect ric fan is temperature
contro lled and can switch on suddenly even
w hen the eng ine is not running.
- The auxiliary radiator fan switches on auto­ matically when the engine coo lant reaches a
certain temperature and will cont inue to run
until the coolant temperat ure drops.

New tires or wheels
Aud i recommends having all work on tires or
wheels performed by an authorized Audi dealer
or author ized Audi Se rvice Facility . These fac ili­
ties have the proper know ledge and are equipped
with the required too ls and replacement parts.
• New tires do not yet have the optimum grip­
ping properties. Drive caref ully and at moder ­
ate speeds for the first 350 mi les (500 km)
with new tires.
• Only use tires w it h the same design, size (roll­
i ng c ircumference) and as close to the same
tread patter n as poss ible on all four wheels .
• Do not replace t ires individua lly. At least re­
pla ce both t ires on the same axle at the same
t ime .
• Audi recommends that you use Aud i Original
Tires . If you wou ld like to use different tires,
please note that the tires may perform differ­
ently even if they are the same
si ze ¢ ,& .
• If you would like to equip your veh icle w ith a
tire/rim comb inat ion that is different from
what was installed at the factory, consult w ith
an aut horized Aud i dea ler o r authorized Audi
Se rvice Facility befo re making a
purchase ¢,& .
The spare tire* is different from the regular tires
insta lled on the veh icle
-for example, if w inter
tires or w ide tires a re ins talled
-so only use the
spa re ti re* tempo rar ily in case of emergen cy and
d rive caref ully wh ile i t is in use . It should be re ­
p laced w it h a regular t ire as soon as possib le.
Applies to: vehicles with all wheel drive: all four
wheels must be eq uipped w ith tires that are the
same brand and have the same construc tion and
tread pattern so that the drive system is not
damaged by different wheel speeds. For this rea­
son , in case of eme rgency, only use a spare tire*
Wheels
that is the same circ umfe rence as the regular
tires.
A WARNING
--On ly use t ire/rim comb inations and suitab le
wheel bo lts that have been approved by
Aud i. Otherwise, damage to the vehicle and
a n accident could res ult.
-For technical reasons, it is not possible to
use t ires from other ve hicles
-in some cas­
es, yo u cannot even use tires from the same
veh icle model.
-Make sure that the tires you select have
e nough clearance to the veh icle. Rep lace­
ment tires should not be chosen s imply
based on the nomina l size, because ti res
wit h a differe nt constru ction can diffe r
g reatly even if they are the same size . If
there is no t enough clearance, the tires or
the vehicle can be damage d and this can re­
duce dr iving safety and increase the risk of
an accident.
-On ly use t ires that are more than s ix years
old when absolutely necessa ry and drive
carefully when doing so.
- Do not use run -flat tires on your vehicle . Us­
ing them when not perm itted can lead to
veh icle damage or accidents.
- If you install wheel covers on the vehicle, make sure they allow enough air circulation
to cool the brake system. If they do not, t his
could increase the risk of an acc ident.
Tire wear/damage

Wheels
-Inflation pressure that is too low or high can in­
crease tire wear considerab ly.
-Driving quickly through curves, rap id accelera­
tion and heavy b raking increase tire wear .
-Have an authorized A udi dealer or au thorized
Audi Se rvice Facility check the wheel alignment
if there is unusual wear.
-Have the whee ls rebalanced i f an imbalance is
causing noticeab le vib ration in the steering
whee l. If you do not, the tires and other veh icle
components could wear more quickly.
Treadwear indicator
O rigina l equ ipment t ires conta in treadwe ar indi­
cators in the tread pattern, which are b ars that
are 1/16 in. (1.6 mm) h igh and are spaced evenly
aro und the tire perpendic ular to the runn ing d i­
rection¢ fig. 279. The letters "TWI" or triangles
on the tire sidewall indicate the locat ion of the
treadwear indicators.
The tires have reached the mi nimum tread
dept h
ll when they have worn down to the tread­
wear ind icators. Replace the tires with new ones
¢ .&, .
Tire rotation
Rotating t he tires regular ly is recommended to
ensure the tires wear even ly. To rotate the tires,
install the tires from the rear ax le on the front
axle and v ice versa. This will allow the tires to
have approx imately the same length of service
life.
For unidirectional tires, make sure the tires are
installed according to the running direction indi­
cated on the tire
sidewall¢ page 361 .
Hidden damage
Damage to tires and r ims can often occur i n loca­
tions that are hidden . Unus ua l vibrations in the
veh icle or pulling to one s ide may indicate that
there is tire damage. Reduce your speed immedi­
ately. Check the t ires for damage .
If no damage
is visible from the outside, drive s lowly and care­
fully to the nearest authorized Aud i dealer or au-
l) Obey any applicable reg ulations in you r country.

thorized Audi Service Facility to have t he ve hicle
inspected.
A WARNING
Tread that has worn too low or different tread depths on the tires can reduce driving safety.
This can increase the risk of an accident be­
cause it has a negative effect on handling,
d riving through curves, and b raking, and be­
cause it increases the r isk of hydroplaning
when dr iving th rough dee p puddles.

Tires and vehicle load limits.
- The tire must flex more if the
tire pressure is too low or if
the vehicle speed or load are
too high. This heats the tire up
too much. This increases the
risk of an accident because it
can cause the tire to burst and
result in loss of vehicle con ­

Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop.

vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat-
ing
("GVWR"). .,.
339

Wheels
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids plus maximum load. The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­ ty") with an assumed weight of 150 lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle. If you tow
a trailer , the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
340
that less weight can be carried as luggage.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli­
ance sticker label located on the
driver's side B-pillar

fig. 280.
A WARNING
=
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carry ing more weight than
your vehicle was designed to
carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
-Tires on a vehicle that has
been overloaded can fail sud­
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
-Always make sure that the to- tal load being transported
