2016 AUDI RS7 SPORTBACK warning

Checking and Filling
should be between the "min " and "max" mark­
ings. 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 illustration
<::> page 205.
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 15 will il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
electric coolant level sensor, we still recommend
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 cooling
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 re­
sult of overheating.
A WARNING
The cooling system is under pressure and can
get very hot. Reduce the risk of scalding from
hot coolant by following these steps.
-Turn off the engine and allow itto cool down.
- Protect your face, hands and arms from es­ caping 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 applying
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 conditions,
the ethylene glycol in engine coolant can
catch fire .

(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding radia­
tor repair fluid may adversely affect the func­
tion 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 compart­
ment,
always read and heed all WARNINGS
<::>.& in Working in the engine compartment on
page 203 .
.. Requirement: There must be a residual amount
of coolant in the expansion tank
i:::>Q) .
.. Turn off the engine .
.. Let the engine cool down .
.. Place a thick rag over the coolant expansion
tank <::>
page 209, fig. 186 and carefully twist
the cap counter-clockwise
c::> &,.
.. Add coolant mixed in the correct ratio
<::> page 209, Coolant up to the MAX marking.
.. Make sure that the fluid level remains stable.
Add more coolant if necessary.
.. Twist the cap on again
tightly.
Replacement engine coolant must conform to ex­
act specifications <::>
page 209, Coolant.
We recommend using only coolant additive G12+
+, G13 or in an emergency G12+ . Do
not use a
different additive. In an emergency use plain wa­
ter 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 cool­
ant, 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 . Excess
coolant will be forced out through the pressure
relief valve in the cap when the engine becomes
hot.

,&_ WARNING
-The cooling system is under pressure and
can get very hot. Reduce the risk of scalding
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 applying light, downward pressure on the top of
the cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or
hot engine parts. Under certa in condi­
tions, the ethylene glycol in engine cool­
ant can catch fire.
- Antifreeze is poisonous. Always store anti­
freeze in its original container and well out
of the reach of children.
- If you drain the coolant, it must be caught
and safely stored in a proper container
clearly marked "poison" .
(D Note
-Do not add coolant if the expansion tank is
empty. Air could enter the cooling system
and damage the eng ine. If this is the case,
do not continue driving. Seek professional
assistance.
- Coolant pollutes the environment and could
cause an engine fire. Excess coolant will be
forced out through the pressure relief valve
i n the cap when the engine becomes hot .
- If, in an emergency, only water can be add­ ed, the correct ratio between water and an­
tifreeze
¢ page 209 must be restored as
soon as possible.
@ For the sake of the environment
Drained coolant should not be reused. Always
dispose of used coolant while observing all
environmental regulat ions.

Checking and Filling
Radiator fan
The radiator fan switches on automatically by it­
self .
An auxiliary electric radiator fan switches on and
off depending on coolant temperature and other
vehicle operating conditions.
After you switch the engine off, the auxiliary fan
can continue running for up to 10 minutes -even
with the ignition off. It can even switch on again later by itself ¢&. , if
- the temperature of the engine coolant rises due
to the heat build-up from the engine in the en­ gine compartment, or
- the engine compartment heats up because the
vehicle is parked in intense sunlight.
A WARNING
--
- To reduce the risk of personal injury never
touch the radiator fan .
- The auxiliary electric fan is temperature
controlled and can switch on suddenly even
when the engine is not running .
- The auxiliary radiator fan switches on auto­
matically when the engine coolant reaches a
certa in temperature and will continue to run
until the coolant temperature drops.
Brake fluid
Checking brake fluid level
Fig. 187 En g in e compar tment: cover on the b rake fluid
rese rvoir
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
¢ & in Working in the engine compartment on
page 203 . .,.
211

Checking and Filling
"' Read the brake fluid level from the brake fluid
reservoir
¢ fig. 187, ¢page 205, fig. 183. The
brake fluid level must be between the "MIN"
and "MAX" markings.
The location of the brake fluid reservoir can be
seen in the engine compartment illustration
c>page205.
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 below
the "MIN" mark, the brake warning/indicator
light
1111 (U.S. models)/ . (Canadian models)
will come on¢
page 14. Do not continue to oper­
ate the vehicle. The complete brake system
should be thoroughly checked by an authorized
Audi dealer or other qualified facility and the
cause corrected . If the brake fluid level is too
low, the brake warning/indicator light will illumi­
nate. Contact an authorized Audi dealer
immedi­
ately.
Changing brake fluid
Have the brake fluid changed by an experienced
technician.
Brake fluid absorbs moisture from the air . If the
water content in the brake fluid is too high , cor­
rosion in the brake system may result after a pe­
riod of time. The boiling point of the brake fluid
will also decrease considerably and decrease
braking performance.
Therefore, the brake fluid must be changed
every
two years.
Always use new brake fluid which con­
forms 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 authorized
Audi
dealer.
Your dealer has the correct tools, the
right brake fluid and the know-how to do this for
you.
212
A WARNING
-
- Brake fluid is poisonous. It must be stored
only in the closed original container out of
the reach of children!
- Brake failure can result from old or inappro­
priate brake fluid. Observe these precau­
tions:
- Use only brake fluid that meets SAE speci­
fication
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 fluid is also indi­
cated 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 efficiency of
the brakes as well as your safety. This
could result in an accident.
(D Note
Brake fluid will damage the paint of your vehi­
cle.
@ For the sake of the environment
Because of the problem of proper disposal of
brake fluid as well as the special tools re­
quired and the necessary expertise, we rec­
ommend that you have the brake fluid
changed by your authorized Audi dealer .
Battery
General information
Under normal operating conditions, the battery
in your Audi does not need any maintenance.
With
high outside temperatures or long daily
drives we recommend that you have the electro­
lyte level checked by a service facility. The elec­
trolyte level should also be checked each time
the battery is charged ¢
page 214.
Have the battery checked when you take your ve­
hicle in for service. You are well advised to re­
place a battery that is older than S years.

With certain types o f air bag dep loyment, the
battery is disconnected from the vehicle electri­
cal system for safety reasons¢&.

your skin, immediately rinse with cold wa­
ter for several minutes and get medical at­
tention .
- If you should ingest any battery acid, seek
medical attention immediately.
- Do not expose the battery to an open flame,
electric sparks or an open light .
- Do not smoke.
- Do not interchange the positive and nega-
tive cables.
- When working on the battery, be sure not to
short-circuit the terminals with tools or oth­
er metal objects. This would cause the bat­
tery to heat up very quickly, which could lead to damage or explosion and personal
injury.
- When a battery is charged, it produces hy­
drogen gas which is explosive and could
cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negative ground cable.
- Before performing any work on the electri­
cal system, switch off the engine and igni­
tion as well as any electrical equipment. The negative cable on the battery must be dis­
connected. If you are just going to replace a
light bulb, then it is enough to switch off
the lights.
- Before disconnecting the battery, switch off
the anti-theft alarm system! Otherwise you
will set off the alarm.
- When disconnecting the battery, first dis­
connect the negative cable and then the
positive cable.
- Before reconnecting the battery, make sure
all electrical consumers are switched off.
Reconnect the positive cable first and then
the negative cable. Never interchange the
cables - this could start a fire!
- Never charge a frozen or a thawed-out bat­
tery. It could explode! If a battery has fro­
zen, then it must be replaced. A discharged
battery can freeze over at 32 °F (0 °C).
- Make sure the vent hose is always attached
to the opening on the side of the battery.
214
- Never use batteries which are damaged .
There is the danger of an explosion! Always
replace a damaged battery.
A WARNING
California Proposition 65 Warning:
- Battery posts, terminals and related acces­
sories contain lead and lead compounds,
chemicals known to the State of California
to cause cancer and reproductive problems.

(D Note
- Do not disconnect the vehicle battery when
the ignition is on or when the engine is run­
ning, otherwise, you will damage electronic
components in the electrical system.
- If your vehicle is going to stand for a long
period of time without being driven, protect
the battery from "freezing", otherwise it
will be damaged and will then have to be re­
placed .
- When opening the doors, the windows low­
er approximately 10 mm automatically. This
function is not available when the battery is
disconnected, which means there is a risk
that the door seal or the window could be
damaged.

thawed battery again because the battery casing
can be cracked due to ice formation and can leak
battery acid.
Battery chargin g (Ma ximum cha rging rate of
30 amp s/14 .8 Volt )
When charging at low voltages (e.g. with a trick­
le cha rger ),
the battery cables do not have to be
d isconnected first. The battery caps should
not
be opened when charging a battery .
It is not necessary to remove the battery from
the luggage compartment, and it is also not nec­
essary to disconnect the cables.
Check ing and Filling
Fast charging the batt ery (charging rate
ab ove 14.8 Volt )
For technical reasons do not use a battery charg­
er that uses vo ltage greater than 14.8 Volt to
charge your vehicle's battery.
A WARNING
=
Charging a battery can be dangerous .
-Always follow the operating instructions
provided by the battery charger manufactur­
er when charging your battery .
