2015 AUDI RS5 CABRIOLET adding oil

180 Driving and en vironm ent
8_ 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 braking effect.
(D 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 switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Warming up and
cooling down
-
By carefully warming up and cooling down
your ve hicle, you can he lp ensure that it is not
overstressed unnecessarily dur ing sporty driv ­
ing.
When warming up, the vehicle is d riven at a
maximum engine speed of 6000 RPM in order
to raise the engine oi l temperature to a mini ­
mum of 140
°F (60 °(). The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can contin ue to run in your ve­
h icle after the engine is switched off. Howev­
er, driving the vehicle to cool it down is part ic­
ularly important. During sporty driving, the
engine and brakes, the ex ha ust system, and
the transm ission all become extremely hot.
B efore you park the vehicle, you shou ld drive it for a few miles/kilometers at
light load in
the low rpm range to allow it to cool down.
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.
.. Always use lead-free gasoline c:> page 190,
Fuel supply.
.. Never run the tank down all the way to emp­
ty .
.. Never put too much moto r oil in your engine
c:> page 199, 't::71 Adding engine oil .
.. Never try to p ush- or tow -sta rt yo ur vehicle.
The catalytic converter is an efficient "clean­
up" device bu ilt into the exhaust system of
t h e vehi cle. The cata lytic conve rter bu rns
many of the pollu tan ts i n t he exh aust gas be­
f ore they are re lease d into the atmosphere.
T he exclusive use of unleaded fue l is critica lly
impor tant for the life of the catalyt ic convert­
er and prope r fu nct ion ing of the engi ne.
8_ WARNING
- T he temperature of the exhaus t system
is high, both when driving and after stop ­
p ing the engine.
- Never touch the exhaus t tail pipes once
they have become hot . This cou ld result
in burns .
- Do not park or operate the vehicle i n
areas where the hot exha ust system may
come in contact with dry grass, brush,
fue l spill or other material wh ich can
cause a fire.
- Do not app ly additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
ver ter or heat shields . Dur ing driv ing, the
substance used for undercoating could
overheat and cause a fire.

196 Checking and filling
-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). -
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~& .
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.
- 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 .
(I) 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.

-If you have the impression your engine
consumes excessive amounts of oi l, we
recommend that you consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in mind that the accurate measurement of
oil consumption requires great care and may take some time. An authorized Audi
dealer has ins tructions about how to
measure oil consumpt ion accura tely.

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.
T he cooling system has been filled at the fac­
tory with a permanent coolant which does not need to be changed. The coolan t consists of a
mixture of specially conditioned water and the
manufacturer 's glycol-based coolant addi-
tive G13 antifreeze with ant icorros ion addi­
tives (50% for USA models ; 60% for Ca nadian
models) . Th is mixture both assures the neces­
sary frost protection and protects metal com­
ponents in the engine's coo ling system from
corrosion and scaling. It a lso raises the boil­
ing point of the coo lant.
D o not reduce the concentration o f the coo l­
ant in the summer by adding plain water .
The
proportion of coolant additive mu st be at
least 50 % but not more than 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, antifree ze is added at
the factory for temperatures down to:
- -31° F(-35°C)USA
- - 4 0 ° F ( -40 °C) Canada.
I f you must add coo lant, use a m ixture of wa­
ter and coolant addit ive. Mixing the coolant
addi tive wi th disti lled wate r is recommended.
A WARNING
Be fore yo u check any thing in the engine
compartment, always read and heed all
WARNI NGS
~ .&. in Working in the engine
compartment on page 195.
(D Note
- Befo re win ter sets in, have the coolan t
checked to see if t he coolant ad dit ive in

your vehicle is sufficient to meet the cli ­
mate conditions . This is especia lly impor ­
tant if you live in a region where the win ­
ter is extreme ly co ld. If necessary, in­
c rease the p ropo rtion of coo lant add itive
to 60% .
- When adding coolant additive to your
cooling system, remember:
- We re commend using on ly coola nt ad­
d itive G 12++ or G 13 for your veh icle .
T his coolan t ad di tive is availab le a t au­
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor ­
rosion protection. The resulting corro­
sion can cause a loss of coolant and se­
rious engine damage .
- Do not add any type of rad iator leak seal­
ant to your vehicle's engi ne coolant .
Add ing radiator repa ir flu id may adverse ­
ly affect the f unction and performance of
your cooling system and cou ld resu lt in
