2015 AUDI RS7 SPORTBACK oil level

218 Check ing and filling
fig . 188. With a cold engine, the coo lant
l evel should be between the "min" and
"max" markings . When the engine is warm ,
the leve l may be slightly above the "max"
mark ing .
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
9 page 213.
To obtain an accurate reading, the engine
must be switched off .
The expans ion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning l ight in the Auto-Check System
9 page 15 w ill
illum inate unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time .
Coolant loss
Coolant loss may indicate a le ak 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.
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 under pressure and can get very hot. Reduce the risk of scald­
ing from hot coolant by followi ng these
steps .
- 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 with a large, thick rag .
- Turn the cap slowly and very carefu lly in
a counter-clockwise direction w hile ap­
plying light, downward pressure on the
top of the cap . -
To avoid being burned, do not spi ll anti­
freeze or coolant on the exha ust system
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
a nt can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your veh icle's engine coolant. Add­
i ng radiator repair fluid may adverse ly af­
fect the funct ion and pe rformance of you r
cooling system and could result in damage
not cove red by your New Veh icle Limited
War ran ty.
Adding coolant
Be very careful when adding engine coolant.
Befo re you check anyth ing in the eng ine com­
partment,
always read and he ed all WARN­
INGS ¢ ..&. in Working in the engine compart­
ment on page
211.

Brake fluid
Checking brake fluid level
Fig . 192 Engine compar tment: cove r on the brake fl uid
reservo ir
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 211.
,.. Read the brake fluid level from the brake
fluid reservoir¢
fig . 192, ¢ page 213,
fig. 188 .
The brake fluid level must be be­
tween the "MIN" and "MAX" markings.
The location of the brake flu id reservoir can be
seen in the engine compartment illust rat ion
¢ page 213.
The fluid level may drop slightly after some
time due to the automatic adjustment of the
brake pads. This is not cause for alarm.
If the brake fluid level falls
considerably be­
low the "MIN" mark, the brake warning/indi­
cator light . (U.S. models)/ . (Canadian
models) will come on ¢
page 14. Do not con­
tinue to operate the vehicle. The comp lete
brake system shou ld be thoroughly checked
by an authorized A udi dealer or other quali­
fied facility and the cause corrected.
If the
brake fluid level is too low, the brake warning/
indic ator light will illuminate. Contact an au­
thorized Audi dealer
immediately .
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the air. If
t he water content in the brake fluid is too
high, corrosion in the brake system may result
after a period of time . The boiling point of the
brake flu id will also decrease conside rably and
decrease braking pe rformance.
Therefore, the brake fluid must be changed
every two years . Always use new brake flu id
which conforms to Federal Motor Vehicle
Standard "FMVSS 116 DOT 4".
The brake fluid reservoir can be difficult to
reach, therefore, we recommend that you
have the brake fluid changed by your author­
ized
Audi dealer. Your dealer has the correct
tools, the right brake fluid and the know-how
to do this for you.
A WARNING
- Brake fluid is poisonous . It must be stor­
ed only in the closed original container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake fluid. Observe these pre­
cautions:
- Use only brake fluid that meets SA E
specification
J 1703 and conforms to
Federal Motor Vehicle Standard 116.
Always check with your authorized Audi
dealer to make sure you are using the
correct brake fluid. The correct type of
brake f luid is also indicated on the
brake fluid reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left in the system too
long . This can seriously affect the effi­
c ie ncy of the brakes as well as your
safety. This could resu lt in an accident.
(D Note
Brake fluid will damage the paint of your
vehicle .

in P (Park position) and the park brake is
applied.
@) For the sake of the environment
- Changing the engine settings wi ll ad ­
versely affect emission levels . This is det­
rimental to the environment and increas­
es fue l consumption .
- Always observe env ironmental regula­
tions when disposing of old engine oil,
used brake fluid, dirty engine coolant,
spent batteries or worn out tires.
- Undeployed airbag modules and preten­
sioners might be classif ied as Perchlo­
rate Material -spec ial handling may ap­
ply, see www .dtsc .ca .gov/hazardous ­
waste/perch lorate . When the veh icle o r
parts of the restraint system including
airbag modules safety belts wit h preten­
s ioners are scrapped, all appl icable laws
and regulations must be observed. Your
a utho rized Audi dea ler is familiar with
these requirements and we recommend
that you have your dealer perform this
serv ice for you .
