2013 AUDI RS5 CABRIOLET check engine

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 through safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Warming up and
cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv­ ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM in order
to raise the engine oil temperature to a mini­ mum of 140 °F (60 °C) . The tires also only
reach their full road holding capability once
they have warmed up .
The cooling fan can continue 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 . Du ring sporty driving, the
engine and brakes, the exha ust system, and
the transm ission all become ext remely hot.
Before you park the vehicle, you shou ld drive
Dri vin g and en vironm ent 185
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 on environmentally sound manner.
"" Always use lead-free gasoline c> page 202,
Fuel supply.
"" Never run the tank down all the way to emp­
ty.
"" Never put too much motor o il in your engine
<=> page 212, ~ Adding engine oil .
""Never try to push- or tow-sta rt you r vehicle.
The catalyt ic converter is an efficient "clean­
up" device bui lt into the exhaust system of
the ve hicl e. The cata lytic conve rter bu rns
many of t he pollutants in the exha ust gas be­
fo re t hey are re leased into the atmosphere.
The exclusive use of unleaded fue l is critically
important for the life of the catalyt ic convert­
er and proper funct ion ing of the engine.
A WARNING ~
- The temperature of the exhaust system
is high, both when driving and after stop ­
ping the engine.
- Never touch the exhaust tail pipes once they have become hot . This could result
in burns .
- Do not park or operate the vehicle in areas where the hot exha ust system may
come in contact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire.
- Do not apply additional undercoating or rustproof ing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields . Dur ing driving, the
substanc e used fo r undercoating could
overheat and cause a fire. •
•

Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
""Try and keep well below your car's maximum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment.
Fu el consumption, exhaust emissions and en ­
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con­
ditions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
""Shut the engine off when you are not driving
the vehicle.
"" Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traff ic
jams, when waiting for trains to pass at ra il­
road crossings, or at traffic lights that have
l ong wa its on red. Turning the engine
off for
just
30-40 seconds saves more fue l than is
burned starting the engine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However, wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which cou ld result in over-
Driving and environment 187
'
heating or othe r damage to the vehicle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
""H ave your veh icle serviced at regular inter-
vals.
By having your vehicle regu larly serviced by an
au thorized Aud i dea ler helps to ensure that it
runs properly and economic all y. The condition
of your veh icle not on ly affects its safety and
ability to hold its va lue, it a lso affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of o il used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certain
mileage has been driven.
You must drive your vehicle about 3,000 miles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(U) Note
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet. Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission control system and could lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System
and other important vehicle compo­
nents .

200 Cleaning and protec tio n
• Dab at the stain . Start at the outside and
work inwards .
• Once the stain is no longer visib le, use a soft
dry cloth or tissue to soak up the moisture.
Do not use leather cleaning products on Al­
cantara ®.
You may use a suitable shampoo for remov ing
dust and dirt .
Dust and grit in the pores and seams can
scratch and damage the surface. If the car is
l eft stand ing in the sun for long periods, the
A lcantara ® should be protected against direct
sunlight to prevent it from fading. Slight color
variations will develop in normal use and are
not an indication of material deterioration .
@ Note
-Never use chemical solvents (e.g . lighter
fl uid, turpentine), waxes, shoe polish or
similar products on Alcantara ® surfaces .
- To avoid damage, have stubborn stains
removed by a commercial cleaning spe­
cia list.
- Do not use brushes, stiff sponges or sim­
ilarly abrasive cleaning aids.
Safety belts
Only well-maintained safety belts work relia­
bly when needed .
• Keep be lts clean .
• For cleaning, use a mild soap and water sol­
ution . Let be lts dry thoroughly and away
from direct sunlight.
• Do not allow inertia reel safety belts to re­
tract before they are completely dry.
• Check the condition of your safety belts
reg ­
ularly .
Heavily soiled safety belts may not retract
properly .
A WARNING
Damaged safety belts can break in a crash.
-Anything that might damage your safety belts could mean that you and your pas­
sengers would not be adequate ly pro­
tected in an accident.
- Safety belt performance depends on cor­
rect insta llation. Never remove be lts
from the veh icle to clean them .
- Do not use chemical clean ing agents,
bleach or dyes. T hey have corrosive prop­
erties which weaken the webb ing .

Engine oil
Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil .
The engine in your Audi is a sophisticated
power p lant that was bu ilt to exacting specifi­
cations. This eng ine needs the right k ind of
engine oil that meets specifications regarding
quality and viscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changi ng oil within the t ime and mileage
i n tervals printed in you r vehicle's Warranty
&
Maintenance booklet matters a lot more to ­
day than it did years ago . Audi has developed
a specia l quality standard for engine oil that
will help assure that your vehicle's engine w ill
get the lubr ication it needs for proper opera­
tion.

210 Check ing and filling
Modern engine lubrication has taken a quan­
tum leap in the last few years. Many synthetic
oils ava ilable today provide better engine lu­
brication that can outlast traditional petrole­
um-based oils, making them a smart choice
for use throughout the life of your Audi .
Whether you use synthetic or petroleum ­
based engine oil, the oil that you use must
conform to Audi 's oil quality standard
VW 502 00 to he lp keep your vehicle's engine
running smoothly and help prevent the for­
mat ion of harmfu l deposits, sometimes called
"sludge ", that ove r time can lead to expensive
repairs .
At the time of pr int ing , engine o ils available in
the U .S . and Canada that meet the exacting
specifi cations of Audi oi l standard VW 502 00
a re synthetic engine oils. This does not mean,
however, that every syn thetic engine oil will
meet Audi oil standard VW 502 00. So always
be sure that you use an approved oil.
To help prevent the format ion of harmful de ­
posits use only oi l with the fo llowing specifi­
cations printed on the oil container :
Audi oil standard VW 502 00
O il container labe ls may carry the specif ica ­
tion s ingly or in comb inat ion with other des ig­
nations and oil qua lity standards .
Viscosity
Engine oi ls are graded according to their vis­
cosity. The proper viscosity grade oil for your
engine depends on cl imactic or seasonal con­
d itions where you drive. You can use oil with a
viscosity grade of SA E SW40 across all tem ­
pe ratu re ranges for normal driving conditions .
However, if eng ine o il viscos ity grade SA E
SW40 is not avai lab le, you can also use viscos­
ity grade SAE SW -30 or SAE OW-40 as long as
it meets Audi o il quality standard VW 502 00
specif ications .
Because engine oil that meets the Audi oil
standard may not be available everywhere
when you need it, we strongly recommend
that you always carry with you an ext ra quart (
li te r) of oil that exp ress ly con forms to the
VW 502 00 spec ification, in case you have to
top
off the oil while on the road.
Only if the level of the o il is a t or be low the
min imum mark -and no oi l that expressly
conforms to Audi oil standard VW 502 00
specifications is available - may you top
off
with a high quality engine o il, preferab ly syn ­
thet ic-based, tha t mee ts ACEA A3 or API SM
specifications, but even then , only in v iscosity
grades SAE SW-40 , SAE SW-30, o r SA E
OW-40. However, dur ing the entire time be­
tween oil change inte rva ls , never top
off with
more than a total of 0.5 q t/ liter engine o il
t h at does not con form to Audi oi l specification
vw 502 00.
For more informa tion about eng ine oi l tha t
has been approved for your veh icle, please
contac t either yo ur authorized Aud i deale r or
Audi C ustome r Re lations at 1 (800) 822 -2834
or visit our web site at www .audiusa.com or
www.aud icanada .ca. Here you w ill also find a
current list of oils (manufacturers, brand
names e tc.) tha t conform to Audi oil s tanda rd
vw 502 00 .
Changing the engine oil
The eng ine oi l and oil fi lter must be changed
according to the mileage (kilometers) and
time intervals specified in your ve hicle's War­
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil ca n reduce eng ine performance and
can lead to expensive engine repa irs .
Changi ng the oil at the recommended inter­
vals is so very important because the lubricat­ ing proper ties of oil decrease gradually during
norma l veh icle use . If you are not sure when
you have your oil changed, ask your author­ ized Audi Serv ice Adv isor.
Under some circumstances the engine oil
shou ld even be cha nged more frequent ly .
Change oil more often if you drive mostly
sho rt distances, operate the ve hicle in dusty
areas o r most ly unde r stop-and-go t raff ic con-
di tions, o r when you use your vehi cle where .,..

temperatures stay below freezing point for l ong periods.
Detergent add itives in the o il w il l make fresh
oil look dark after the eng ine has been run ­
ning fo r a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am ag e or m alfun ction s due to lack of
ma intenanc e
It is essential that you change your oil at the
r ecommended inte rva ls using only engine o il
t hat complies with A udi oi l standard
VW 502 00 . Your Limited New Vehicle War ­
ranty does not cover damage or malfunctions
due to fa ilure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage u nless you present to
the dea ler p roof in the fo rm of Serv ice or Re­
pa ir Orde rs that all s chedu led maintenance
was pe rformed in a t imely manner .
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In o rder to provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amo unt of o il. Oil consumption varies from
engine to engine and may change significantly
over the life of the engine. Typ ica lly, engines
with a specified break-in period (see
¢
page 184) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con ­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revo lutions per m inute) at
which the engine is operated, the ambient
temperature and road condit ions. Furthe r fac­
tors are the amount of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oil. As any engine is s ubje ct to
Checkin g and fillin g 211
wear as mi leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
Wi th a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
1\1 in the instrument cluster lights up , you
shou ld check the oil leve l as soon as possib le
¢
page 212. Top off the oil at your earliest
convenience

A WARNING
Before you check anythi ng i n the engine
compartment, always read a nd heed all

in Working in the engine
c ompartment on page 207.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
- The oil pressure warning display. is
not an indi cator of the oil le vel. Do not
rely on it . Instead, check the oil level in
your engine at regu lar intervals, pref­
erably ea ch time you r efuel, and alway s
before going on a long trip .
-If you have the impression you r engi ne
c ons umes ex cess ive amoun ts of o il, we
recommend that you consul t an a uthor­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in mind that the accurate measurement of
oil consumption requ ires great care and
may take some t ime. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.
