2012 AUDI A5 COUPE heating

230 Cleaning and protec tio n
• Dab at the stain . Start at the outside and
work inwards .
• Once the stain is no longer visible, use a
soft dry cloth or t issue to soak up the mois­
ture.
Do not use leather cleaning products on Al­
cantara ®.
You may use a suitable shampoo for removing
dust and dirt .
Dust and gr it in the pores and seams can
scratch and damage the surface. If the car is
l eft standing 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 .
- Never use chemical solvents (e.g . lighter
fluid, turpentine), waxes, shoe polish or
s imilar products on Alcantara ® surfaces .
- To avoid damage, have stubborn stains
removed by a commerc ial cleaning spe­
cia list.
- Do not use br ushes, stiff sponges or sim­
i larly 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 b reak in a crash . -
Anything that might damage your safety
be lts could mean that you and your pas­
sengers would not be adequately 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. They 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

' Engine compartment
Be especially careful when cleaning the en­
gine comportment.
Alwa ys switch off the ign ition before cle an­
i ng the eng ine
c> .&, .
Plenum pan el
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.
Cor rosi on protec tion
The engine compartment and transmission
have been corrosion -protected at the factory .
Good anti- corrosion treatment is very impor­
tant, particu larly in the w inter.
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. ..,_

244 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 G12++ antifreeze
with anticorrosion add itives (SO% for USA
models; 60% for Canadian models). This mix­
ture bo th assures the necessary frost protec­
tion and protects metal components in the
engine's coo ling 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 antifree ze protection and cooling efficien­
cy. If the coolant frost protection is too low,
the coolant could freeze and damage the vehi ­
cle heating and engine cooling system .
For year-round driving, antifree ze is added at
the factory for temperatures down to:
- - 31°F (- 35 °C) USA
- -40°F ( - 40°C) Canada.
You can mix the G12 ++ coolant additive with
other additives (G12+ or G12). Always check
with your authorized Audi dealer.
_&. WARNING
Before you check anything in the engine
compartment, always read and heed all
WARNINGS ¢
A in Working in the engine
compartment on page 237.
(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 especia lly impor­
tant if you live in a reg ion where the win ­
ter is extreme ly cold. If necessary, in­
crease the proportion of coolant additive
to 60% .
- When adding coolant additive to your
cooling system, remember :
- We recommend using only coolant ad­
ditive G12++ (check the label) for your
vehicle . This coolant additive is availa­
b le at authorized Audi dealers . Other
types of antifreeze can significant ly re­
duce corrosion protection. The result­
ing corrosion can cause a loss of cool­
ant and serious engine damage.
- Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant.
Add ing radiator repair fluid may adverse ­
ly affect the function and performance of
your cooling system and cou ld resu lt in
damage not covered by your New Vehicle
Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with
a quick glance.
Fig. 206 E ngin e compart men t: Coo lant expans ion tank
.,. Before you check anything in the engine
compartment,
always read and heed all
WARNINGS ¢&. in Working in the engine
compartment on page 23
7.
.,. Turn off the ignition .
.,. Read the engine coolant level from the
coo lant expansion tank¢
fig. 206. With a
cold engine, the coolant level should be be-
tween the "MIN" and "MAX" markings . ..,..

When the engine is warm, the level may be
slightly above the
"MAX" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration ¢ page 239.
To obtain an accurate reading, the engine must be switched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coolant level is too low, the warning
light in the Auto-Check System ¢page
31 will
blink until you add coolant and the level has
been restored to normal. Even though there is
an electric coolant level sensor, we still rec­
ommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling
system. In the event of coolant loss, the cool­
ing system should be inspected immediately
by your authorized Audi dealer.
It is not
enough merely to add coolant.
In a
sealed system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheating.
& WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect your face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction while ap­
plying light, downward pressure on the
top of the cap.
- To avoid being burned, do not spill anti­ freeze or coolant on the exhaust system or hot engine parts. Under certain condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
Checking and filling 245
@ Note
Do not add any type of radiator leak seal­
ant to your vehicle's engine coolant. Add­
ing radiator repair fluid may adversely af­
fect the function and performance of your
cooling system and could result in damage not covered by your New Vehicle limited
Warranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the engine com­
partment,
always read and heed all WARN­
INGS ¢ & in Working in the engine compart ­
ment on page 23
7.
.,. Turn off the engine .
.,. let the engine cool down.
.,. Place a thick rag over the coolant expansion
tank ¢ page
244, fig . 206 and carefully turn
the cap counter-clockwise ¢
&_.
.,. Add coolant.
.. Twist the cap on again tightly.
Replacement engine coolant must conform to
exact specifications ¢ page
244, Coolant.
Even in an emergency, if coolant addi-
tive G12++, G12+ or G12 is
not available, do
not use a different additive. Use plain water
instead until you can get the correct additive
and can restore the correct ratio. This should
be done as soon as possible.
If you have lost a considerable amount of
coolant , then you should add cold antifreeze
and cold water only when the engine is cold.
Always use new engine coolant when refilling.
Do not fill coolant above the "MAX" mark. Ex­
cess coolant will be forced out through the pressure relief valve in the cap when the en­
gine becomes hot.
A WARNING
- The cooling system is under pressure and
can get very hot. Reduce the risk of ...,
