2013 AUDI RS5 CABRIOLET heating

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 .
- When clean ing your safety belts, inspect
them for damage. If you discover dam­
age, see your authorized Audi dealer .
-Always read and heed all WARNINGS and other information
Q page 189 .
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Al ways s witch off the ign it ion befo re clea n­
ing the engine ¢ Li:::,..
Plenum panel
Remove leaves from the plenum panel in front
of the windshield under the engine hood . This
prevents the water drain holes from becoming
blocked, and it prevents debris from enter ing
the vehicle interior through the heating and
ventilat ion ducts.
Corro sio n p rot ection
T he engine compartment and transmission
have been corrosion-protected at the factory .
Good anti- co rrosion treatmen t is very impor­
tant, particu larly in the w inte r.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum panel
shou ld be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
should be washed as well. .,..

214 Checking 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 G13 antifreeze with
anticorrosion add itives (50% for USA models;
60% for Canadian models). This mixtu re both
assures the necessary frost protection and
protects metal components in the engine 's
cooling system from corrosion and scaling. It
also raises the boiling point of the coolant .
Do not reduce the concentration of the cool­
ant in the summer by adding plain water .
The
proportion of coolant additive must be at
least 50% but not more than 60%
to main­
tain antifreeze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi­
cle heating and eng ine cooling system .
For year-round driving, antifreeze is added at
the factory for temperatures down to:
- -31 ° F ( - 3 S °C) USA
- -40 °F ( - 40 °C) Canada .
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ~
A in Working in the engine
compartment on page 207.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­
mate conditions . This is especially impor­
tant if you live in a region where the win­
ter is extremely cold. If necessary, in- crease the
proportion of coolant additive
to 60%.
- When adding coolant additive to your
cooling system, remember:
- We recommend using on ly coolant ad­
ditive G12++ or G13 for your vehicle.
This coolant additive is availab le at au­
thor ized Audi dealers. Other types of
antifreeze can significantly reduce cor­
rosion protection. The resulting corro­
sion cah 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 engine coolant .
Adding radiator repair fluid may adverse­
ly affect the function and performance of
your cooling system and could result in
damage not covered by your New Veh icle
Limited Warranty.
· Checking the engine coolant level and
adding coolant
Be very careful when adding engine coolant.

Before you check anything in the engine com­
partment,
al ways r ead and heed all W ARN­
ING S ¢ A in Working in the engine compart­
ment on page 207.
The "MIN" und "MAX" markings are found on
the bi-level disc in the interior of the coolant
expansion tank
¢ fig . 181.
.,. Park your vehi cle on a level sur face.
.,. Turn off the ignition .
.,. Let the engine coo l down .
.,. Place a thick rag over the coolant expansion
tank and
c a refully turn the cap counter ­
clockwise ¢
.&,.
.,. Read the engin e coolant le vel inside the
coolant expans ion tank ¢
fig. 180,
¢ page 209, fig . 177. With a cold engine,
the coolant leve l should be between the
" M IN" and "MAX" mark ings
¢ fig. 181
-arrows- . When the eng ine is warm, the lev­
el may be slightly above the "MAX" marking.
.,. The MAX marking may be covered with a
maximum of 1 mm of coolant when yo u
fill
coolant .
.,. Twist the cap on again tightly.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
¢ page 209.
To obtain an accurate read ing, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an electric coolant level sensor .
When the coo lant level is too low, the warning
light in the A uto-Check System¢
page 18 wi ll
b lin k until you add coo lant and the level has
been restored to norma l. Even though there is
an electric coolant level sensor, we sti ll rec­
ommend you check the coolant leve l from
time to time.
Coolant loss
Coolant loss may indicate a leak in the coo ling
system . In the event of coolant loss, the cool ­
i n g system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
Checkin g and fillin g 215
In a sealed system, losses can occur on ly if
the boiling point of the coolant is exceeded as
a resu lt of overheating.
Adding coolant
Rep lacement engine coolant must confo rm to
exact specificat ions¢
page 214, Coolant .
We recommend using only coo lant add itive
Gl2++, Gl3 or i n an emergency Gl 2+ . Do not
use a different add itive. In an emergen cy use
plain water until you can ge t the correct addi­
tive and can restore the correct ra tio. This
sho uld be done as soon as possib le .
If you have lost a cons iderab le amount o f
coolant, then you sho uld add cold ant ifreeze
and co ld water on ly when the engine is cold.
A lways use
new engine coo la nt when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be fo rced out through the
pressure relief valve in the cap when the en­
gine becomes hot.
_& WARNING
- Th e cooling system is un der pressure and
can get very hot. Reduce the risk of
scalding from hot coolant by following
these ste ps.
- Turn off the engine and allow it to coo l
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering
the cap w ith a large, th ic k rag.
- Turn the cap s lowly and very carefully
i n a counter-clockwise direction while
applying light, downward pressure on
the top of the cap.
- To avoid being bu rned, do not spill an­
tifree ze or coolant o n the ex haust sys­
tem o r hot engine p arts. Under ce rtain
con ditio ns, the ethy lene glycol in en­
gine coolant can catch fire.
- Antifreeze i s poisonous. Always s tore an­
tifreeze in its original container an d well
out of the reach of children .

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. Thi s applies especially to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must
be correctly taken apart and then properly put
back together to help prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper·
ly resealed.
F or your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Ga s discharge lamps (Xenon lights}*:
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight are identified by
the high voltage sticker.
A WARNING
Changing Xenon lamps without the neces­
sary equipment can cause serious personal
in jury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On vehicles equipped with gas discharge
bulbs (Xenon light)* life-threatening in­
juries can result from improper handling
of the high-voltage portions of such
lamps!
- Only your authorized Audi dealer or a
qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an author ized Audi dealer or other quali­
fied workshop. Ser ious personal injury
may result from improperly performed
work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
9 page 200, Engine compart­
ment
9 Lr:,. .
-It is best to ask your authorized Audi
dealer whenever you want to change a
bulb.
