Changing the engine oil
We recommend that hove your oil changed by on
authorized Audi dealer or a qualified servi ce sta ­
tion.
Befo re yo u check anything in t he engine compart ­
ment,
alway s read and h eed all WARNINGS ¢ &
in Working in the engine comportment on
page
193.
The eng ine o il must be changed according to the
i nte rvals spec ified in yo ur War ranty
& Ma inte ­
nance boo klet. This is ve ry important because the
l ubricating prope rties of oil diminish gradua lly
during norma l vehicle us e.
Un der some c ircumstances the engine oil should
be c hanged more freq uent ly. Change oi l more of ­
ten if you drive mostly s hort distances, operate
the ve hicle in dusty areas or under
predominantly ..,.

a co .... N
" N .... 0 00 \,;J ' stop-and-go traffic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. This is norma l and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
quired, we strong ly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
-When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help 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 total amount of oil in your engine .
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Cont inuous contact w ith used engine oil is
harmful to your sk in. Always protect your
sk in by washing oil off thoroughly w ith soap
and water.
@ Note
Never mix oil addit ives with your engine o il.
These additives can damage your eng ine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
Checking and Filling
@) For the sake of the environment
-Before changing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oi l properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled wit h a mixture
of purified water and coolant additive at the fac ­
tory. This coolant must not be not changed.
T he coolant level is monitored through
the . in­
dicator light
r=;, page 14. However, we do recom­
mend occasionally checking the coolant leve l
manua lly.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coo lant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow­
ing coolant additives. These additives may be
mixed with each other .
Coolant additive Specification
Gl2evo
TL 774 L
Gl2++ TL 774 G
Gl3 TL 774

The amount of coolant additive that needs to be
mixed with water depends on the climate where
the vehicle wi ll be operated .
If the coolant addi ­
tive percentage is too low, the coolant can freeze
and damage the engine.

Observe the safety precautions~ page 193,
Working in the engine compartment .
Checking the engine coolant level
• Park the vehicle on a leve l surface .
• Switch the ignition off.
• Read the coolan t leve l on the coo la nt expansion
tank
~page 196, fig . 181. The coolant level
must be between the MIN and MAX markings

when the engine in cold. When the engine is
warm it can be slightly above the MAX marking .
Adding coolant Requirement: there must be a residual amount of
coolan t in the expansion tan k
~CD -
• Let the engine cool down .
• Place a cloth over the coolant expansion tank
cap and unscrew the cap counterclockw ise
~ & -
... Add coo lant m ixed in the cor rect ratio
~ page 199 up to the MAX marking.
• Make sure that the fluid level remains stab le .
Add more coolant if necessary .
• Close the cap securely.
Coolant loss usually ind icates there is a leak . Im­
mediate ly drive your vehicle to an authorized
Audi dealer or authorized Audi Service Fac ility
and have the cooling system inspected. If the
cooling system is not leaking, a loss can come
from the coolant boiling through overheat ing
and being pushed out of the cooling system .
A WARNING
- The cooling system is under pressure. Do
not open the coo lant expansion ta nk cap
when the engine is hot. This increases the
risk o f bur ns.
- The coolan t addi tive and the coolant can be
dangerous to your health. For t his reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.
- When working in the engine compartment,
remember that the radiator fan can switch
on even if the ignition is switched off, which
increases the risk of injury.
(D Note
Do not add coolant if the expansion tank is
empty. A ir cou ld enter the cooling system and
damage the engine. If this is the case, do not
continue driving. See an authorized Audi deal­
er or authorized Audi Serv ice Facility for assis­
tance.

Vehicle battery
The term "vehicle battery " refers to the 12 Volt
bat tery in your vehicle.
Not running the vehicle for long pe riods of
t ime
If you do not drive your vehicle for several days o r
weeks , electri cal equipment is gr adually scaled
back or switched off . This reduces energy use and
ensures the veh icle w ill be able to start after long
periods of time
c::> page 126 . Some conve nience
functions, s uch as interior lighting or power seat
adj ustment, may not be available under certa in
circumstances. These convenience f unct ions w ill
be ava ilab le aga in once you switch the ignition on
and start the engine .
E ven w hen electrica l equ ipme nt is swi tched off,
the equipment can still d rain the vehicle battery
if the vehicle is not driven for long periods of
time . Deep draining results in a chemical reaction
that destroys the inside of the vehicle battery .
The vehicle battery must be charged every month
t o reduce the risk of this happening

Wheels and Ti re s
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.
.,,. Mark 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 locat ion
with as litt le exposure to light as
possible .
&_ WARNING -
-Never drive faster than the
maximum permitted speed
for your tires. This could cause the tires to heat up too much .
This increases the risk of an
acc ident because it can cause
the tire to burst.
-Always adapt your driving to the road and traffic condi-
Wheels
tions. Drive carefully and re ­
duce your speed on icy or slip­
pery roads . Even winter tires
can lose traction on black ice .
@ N ot e
-Please note that summer and
winter tires are designed for
the condit ions that are typical
in those seasons. Audi recom­
mends using winter ti res dur ­
ing the winter months. Low
temperatures significantly de­ crease the e lasticity of summ­
er tires , which affects traction
and braking ab ility . 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 protect ion for this and
could be permanently dam­
aged by road salt or similar
substances.

Tire pre ssure mon itoring
system *
means a system that detects
when one or more of a vehicle's
tires are underinflated and illumi­
nates a low tire pressure warning
telltale.
Tread
means that portion of a tire that

Tread separation
means pulling away of the tread
from the tire carcass.
Treadwea r indicators (TWI)
means the projections within the
principal grooves designed to give
a visual indication of the degrees
of wear of the tread. See

Uniform Tire Quality Grading
is a tire information system devel­
oped by the United States Nation­

Wheels
parisons among tires . The U TQG
is not a safety rating and not a
guarantee that a tire will last for
a prescribed number of miles
(kilometers) or perform in acer­
tain way . It simply gives tire buy ­
ers additional information to
combine with other considera­
tions, such as price, brand loyalty and dealer recommendatio ns. Un­
der UTQG, tires are graded by the
tire manufacturers in three areas :

Number (TIN)
T his is the tire's "se ria l number" .
It begins with the letters "DO T"
and indicates that the tire meets
all federal standards. The next
two numbers or letters indicate
the plant whe re it was manufac­
tured, and the last four numbers
represent the week and year of
manufactu re . For example,
DOT .. . 2217 ...
means that the tire was produced
in the 22nd week of 2017 . The

vehicle with a tire/rim combina­
tion that is different from what
was installed at the factory, con­
sult with an authorized Audi
dealer or authorized Audi Service Facility before making a pur­
chase
i=:> &, .
Because the spare tire* is differ­
ent from the regular tires instal­
led on the vehicle (such as winter
tires or wide tires), only use the spare tire* temporarily in case of
emergency and drive carefully
while it is in use. It should be re­
placed with a regular tire as soon
as possible.
Applies to: vehicles with all wheel drive: all four wheels must be
equipped with tires that are the
same brand and have the same construction and tread pattern so
that the drive system is not dam­ aged by different wheel speeds .
~ For this reason, in case of emer-
-~ gency, only use a spare tire* that

is the same circumference as the
regular tires.
&_ WARNING
-
-Do not use steel rims that are
17 inches or larger. Other­
wise, damage to the vehicle
and an accident could result.
-Only use tire/rim combina­ tions and suitable wheel bolts
that have been approved by
Audi. Otherwise, damage to
the vehicle and an accident
could result.
-For technical reasons, it is not possible to use tires from oth­
er vehicles -in some cases,
you cannot even use tires from the same vehicle model.
-Make sure that the tires you select have enough clearance
to the vehicle. Replacement
tires should not be chosen
simply based on the nominal
size, because tires with a dif­
ferent construction can differ
greatly even if they are the
same size. If there is not
enough clearance, the tires or
the vehicle can be damaged
and this can reduce driving
safety and increase the risk of
an accident.
