2013 AUDI S4 SEDAN adding oil

A WARNING ,~ ~
After driving through water, mud, slush,
etc., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full brak ing effect.
([) Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switch the engine off when driving
th rough water.
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for you r vehi­
cle to drive th rough safely.
- Avoid dr iving through sa lt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in an environmentally sound manner.
11-Always use lead-free gasoline q page 210,
Fuel supply .
"'" Never run the tank down a ll the way to
empty.
11-Never put too much motor oil in your en-
gine
q page 220, ~ Adding engine oil .
11-Never try to push -or tow-start your veh icle .
The catalytic converter is an efficient "clean­ up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be­
fore they are released into the atmosphere .
Drivin g and en vironm ent 193
The exclusive use of unleaded fuel is critically
important for the life of the catalytic convert­
er and proper funct ion ing of the engine.
A WARNING
-
- Do not park or operate the vehicle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other mate rial wh ich can
cause a fir e.
- Do not apply additional undercoating or rustp roof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ve rter or heat shields. During driv ing, the
substance used for undercoating co uld
overheat and cause a fire.
(D Note
- Be aware that just one tank filling with
leaded fu el w il l already ser iously de­
gra de the performance of the catalytic
c onverte r.
- Do not ex ceed t he cor rect eng ine oil level
qpage 220.
- Do not drive until the fue l tank becomes
comple tely empty. The engine co uld m is­
fire . Unburned fuel could also get in to
the exhaust system and th is co uld cause
the catalytic converter to overheat .
- Do not turn off the ignition while the ve ­
hicle is moving.
- Do not continue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalytic converte r. T his
cou ld result in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained prope rly
and in accorda nce w ith the serv ice rec­
ommendat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w ill impair
the function of the em ission contro l
system and could lead to damage . ..,. •

216 Checking and filling
-Apply the parking brake.
- Move selector lever of automatic trans- mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­ ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
-Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- 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 of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- 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 hazards~&, .

222 Check ing and filling
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro ­
tects the engine from freezing in the winter .
The cooling system is sealed and generally re­
quires little attention.
The cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly ­
col-basedcoolant additive G 13 antifreeze with
anticorrosion add itives (SO% for USA mode ls;
60% for Canadian models). This mixture both
assures the necessary frost protection and protects metal components in the engine's
cooling system from corrosion and scaling. It
a lso raises the boiling point of the coolant .
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water .
The
p ro po rti on of c ool ant add it iv e mu st b e at
lea st 50 % but not mo re th an 60%
to main­
tain antifree ze protection and cooling efficien­
cy. If the coolant frost protect ion is too low,
the coolant could freeze and damage the veh i­
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31° F(-3S°C)USA
- - 40 ° F ( - 40 °C) Canada.
_& WARNING
Before yo u check anything in the engine
compartment, always read and heed all
WARNINGS
¢ &. in Working in the engine
compartment on page 215.
(]) Note
-
- Before winter sets in, have the coolant
checked to see if the coo lant additive in
your vehicle is s uffic ient to meet the cli­
mate cond it ions . Th is is especially impor­
tant if you live in a region where the w in­
ter is extremely cold . If necessary, in- crease the p
roportion of coo lant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend us ing on ly coolant ad­
d itive G12++ or G13 for your veh icle .
This coolant additive is availab le at au­
thor ized Audi dealers. Other types of
ant ifreeze can s ignificantly reduce cor­
rosion pro tection. The resulting cor ro­
sion can cause a loss o f coolant and se ­
rious engine damage.
- Do not add any type of rad iator leak seal­
ant to yo ur vehicle's engine coolant .
Adding radiator repair fl uid may adverse ­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Veh icle
Limited Warranty.

.. Read t he engine coolant level from the
coo la nt expansion tank ¢
fig. 170 ,
r=:> page 217, fig . 167. With a cold engine,
the coolant leve l should be between the
"MIN" and "MAX" markings . When the en­
gine is warm, the level may be slightly above
the "MAX" marking.
IJII,

The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
q page 217 .
To obtain an accurate read ing , the eng ine
must be switched off .
The expa nsion tank in you r vehicle is equipped
with an elec tric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System

b lin k until you add coo lant and the level has
been restored to norma l. Even t hough the re is
an e lec tric coolant level sensor, we s till rec ­
ommend you check the coolant leve l from
time to time .
Coolant loss
Coolant loss may indi cate a leak in the coo ling
sys tem. In the event of coolant loss, the cool­
ing system should be inspected immedia tely
by your authorized A udi dealer. It is not
enough merely to add coolant.
I n a
s ealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
A WARNING
The cooling system is unde r press ure and
can get ve ry hot. Reduce the risk of sca ld­
ing from hot coolant by following these
steps.
- Turn off the engine and allow it to coo l
down.
- 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 carefu lly in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
t op of the cap .
- To avoid being bu rned, do not spill ant i­
freeze or coo lant on the exhaust system
