2016 AUDI A6 oil

Checking and Filling
@ Tips
-The oil pressure warning display. is not
an indicator of the oil level. Do not rely on
it. Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going
on a long trip.
- If you have the impression your engine con­
sumes excessive amounts of oil, we recom­
mend that you consu Lt your Audi dealer to
have the cause of your concern properly di­
agnosed . Keep in mind that the accurate
measurement of oil consumption requires
great care and may take some time. Your
Audi dealer has instructions about how to
measure oil consumption accurately.
Checking the engine oil level
The engine oil level can be checked in the Info­
tainment system

fig. 187. Add engine oil if the bar of
the oil level indicator is near "min"
¢page 220.
Depending on the way the vehicle is driven and
the operating conditions, oil consumption can be
up to 1/2 quart per 600 miles (0 .5 liter per
220
1,000 km). Consumption may be higher within
the first 3,000 miles (5,000 km).
Because of this, the engine oil level must be
checked regularly. It would be best to check each
time you refuel your vehicle and before long
drives.
{!) Tips
The oil level indicator in the instrument clus­
ter display is only an informational display. If
the oil level is too low, a minimum oil warning
appears in the instrument cluster. Add oil. If
the hood was opened, the current oil level is
shown in the instrument cluster the next time
the ignition is switched on.

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion.
Before you check anyth ing in the eng ine compart­
ment,
alw ays read and h eed all WARNING S c:> .&.
in Working in the engine compartment on
page 216.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet. This is very important because the
l ubricat ing propert ies of oil d iminish gradually
during normal vehicle use.
Under some circumstances the engine o il should
be changed more frequently . Change oil more of­
ten if you drive mostly short distances, operate
the veh icle in dusty areas or under predominant ly
stop-and -go traffic condit ions, or have yo ur vehi­
cle whe re temperatures remain below freezing
for extended periods.
Ch eck ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem o f proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that yo u have
your o il changed by an authorized
Audi dealer or
a qual ified service stat ion.
If y ou choo se to chan ge your oil your self , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When remov ing the oil drain plug w ith your
f ingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
he lp prevent hot oil from running down your
arm.
- Drain the oil into a container designed for
this purpose, one large enough to hold at least the tota l amou nt of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
«I) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adverse ly affect yo ur Audi limited New Vehi­
cle Warranty.
@ For the sake of the environment
- Before chang ing yo ur oi l, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly .

- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station.
Cooling system
Coolant
T he 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 factory
with a permanent coolant which does not need to be changed . The coolant consists of a mixture of
specially conditioned water and the manufactur ­
er's glycol-based coolant additive G13 antifreeze
with anticorrosion additives (50% for USA mod­
els · 60% for Canadian models). This mixture
'
both assures the necessary frost protection and
protects metal components in the engine 's cool­
ing system from corrosion and scaling. It also
raises the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water.
The propor­
tion of coolant additive must be at least 50% but not more than 60%
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant could
freeze and damage the vehicle heating and en­
gine cooling system .
For year-round driving, antifree ze is added at the
factory for temperatures down to:
- -31 °F ( -3 5 °C) USA
- - 40 °F ( - 40 °C) Canada.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
_& WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN-
222
INGS ~&. in Working in the engine compart­
ment on page 216.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in your
vehicle is sufficient to meet the climate con­ ditions. This is especially important if you
live in a region where the winter is extreme­
ly cold . If necessary, increase the proportion
of coolant additive to 60%.
- When adding coolant additive to your cool­
ing system, remember:
- We recommend using only coolant addi­
tive G12++ or G13 (check the label) for
your vehicle. This coolant additive is avail­
able at authorized Audi dealers. Other
types of antifreeze can significantly re­
duce corrosion protection. The resulting
corrosion can cause a loss of coolant and
serious engine damage .
- Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Adding ra ­
diator repair fluid may adversely affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Limited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

s ion tank
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
~ A in Working in the engine compartment on
page 216. ..,.

• Park your vehicle on a level surface.
• Switch
off the ignition.
• Read the engine coolant level from the coolant
expansion tank¢
fig. 189, ¢ page 218,
fig. 186.
With a cold engine, the coolant level
should be between the "min" and "max" mark­
i ngs . When the engine is warm, the level may
be s light ly above the "max " marking.
The location of the coolant expans ion tank can be
seen in the engine compartment illustrat ion
¢pag e 218.
To obtain an accurate reading, the engine must
be sw itched
off.
The expansion tank in your vehicle is equipped
with an electric coolant level sensor.
When the coo lant level is too low, the warning
light in the Auto-Check System
c:> page 15 wi ll il­
luminate until you add coolant and the level has
been restored to normal. Even though there is an
e lectric coolant level sensor, we still recommend
you check the coolant level from t ime to t ime.
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 coo lant is exceeded as a re­
sult of overheat ing.
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 eng ine and allow it to 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.
Checking and Filling
-To avoid being burned, do not spill anti­
freeze or coolant on the exhaust system or
hot engine parts. Under certain cond itions,
the ethylene glycol in engi ne coolant can
catch fire.
(D Note
Do not add any type of radiator leak sealant
to your vehicle's engine coolant. Add ing 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

We recommend using only coolant additive Gl2+
+ , Gl3
or in an emergency Gl2+. 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 coo l­
ant, then you should add cold antifreeze and cold
water only when the engine is co ld.
Always use
new engine coolant when refi lling.

.,. Read the brake fluid level from the brake fluid
reservoir
¢fig. 190, ¢page 218, fig. 186. 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
¢page 218.
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) ;II (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.
Checking and Filling
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 ape ­
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.
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.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.

Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­
cle's
Gross Vehicle Weight Rat­
ing
("GVWR") .
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in­
tended to carry ("seating capaci­
ty") with an assumed weight of 1 SO lbs. (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any
luggage in the vehicle. If you tow
a trailer, the weight of the trailer hitch and the tongue weight of
the loaded trailer must be includ­
ed as part of the vehicle load.
The
Gross Axle Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles.
The fact that there is an upper limit to your vehicle's Gross Vehi-
244
cle Weight Rating means that the
total weight of whatever is being carried in the vehicle (including
the weight of a trailer hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard weights assumed mean
that less weight can be carried as
luggage.

&_ WARNING ~
Overloading a vehicle can cause
loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and increase the risk of the loss of
vehicle control.
-The brakes on a vehicle that has been overloaded may not
be able to stop the vehicle
within a safe distance.
