Checking and Filling


— Maintain enough distance when you are re-
moving the oil drain plug. While doing this,
keep your forearm parallel to the ground to
reduce the risk of hot oil dripping down your
arm.
— Drain the oil into a container designed for
this purpose that is large enough to hold the
full amount of oil in your engine.
— Engine oil is poisonous. Always store out of
reach of children.
— Prolonged contact of used engine oil with
the skin may cause skin damage. Always
wash oil off immediately with soap and wa-
ter to protect your skin.


@) Note
Do not mix any additives with the engine oil.
Additives may cause engine damage that is
not covered by your New Vehicle Limited War-
ranty.
() For the sake of the environment
— Before changing the engine oil, make sure
you can dispose of the used engine oil cor-
rectly.
— Engine oil must always be disposed of cor-
rectly. Do not dump it in the yard, in the for-
est, or in open water, river channels, or sew-
ers.
— Have your used engine oil recycled by bring-
ing it to a used oil collection site or contact
a gas station.
Cooling system
The engine cooling system is filled with a mixture
of purified water and coolant additive at the fac-
tory. This coolant must not be not changed.
The coolant level is monitored using the B indi-
cator light. However, we do recommend occa-
sionally checking the coolant level manually.
Messages
& Turn off engine and check coolant level. See
owner's manual
The coolant level is too low.
Do not continue driving and switch the engine
off. Check the coolant level > page 210.
— If the coolant level is too low, add coolant
=> page 210. Only continue driving once the in-
dicator light turns off.
/_E| Coolant temperature: too high. Let engine
run while vehicle is stationary
Let the engine run at idle for a few minutes to
cool off, until the indicator light turns off.
— If the indicator light does not turn off, do not
continue driving the vehicle. See an authorized
Audi dealer or authorized Audi Service Facility
for assistance.
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
TL774G
TL774)



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

Coolant Freeze protec-
additive tion
Warm min. 40% min. -13 °F
regions max. 45% (-25 °C)
Cold min. 50% max. -40 °F
regions max. 55% (-40 °C)

CG) Note
— Before the start of winter, have an author-
ized Audi dealer or authorized Audi Service
Facility check if the coolant additive in your
vehicle matches the percentage appropriate
for the climate. This is especially important
when driving in colder climates.

Checking and Filling

— If the appropriate coolant additive is not
available in an emergency, do not add any
other additive. You could damage the en-
gine. If this happens, only use water and re-
store the correct mixture ratio with the
specified coolant additive as soon as possi-
ble.
— Only refill with new coolant.
— Radiator sealant must not be mixed with
the coolant.

al information.
Checking the engine coolant level
>» Park the vehicle on a level surface.
> Switch the ignition off.
> Read the coolant level on the coolant expansion
tank > page 205, fig. 142. The coolant level
must be between the markings @) 9 fig. 145
when the engine is cold. When the engine is
warm it can be slightly above the upper mark-
ing.
Adding coolant
Requirement: There must be a residual amount
of coolant in the expansion tank >@).
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Let the engine cool down.
> Place a large, thick towel on the coolant expan-
sion tank cap.

» Remove the cover (@) > fig. 145 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 209 up to the upper marking @)
> fig. 145.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Screw on the cap securely to the right.
Coolant loss usually indicates there is a leak. Im-
mediately drive your vehicle to an authorized Au-
di dealer or authorized Audi Service Facility and
have the cooling system inspected. If the cooling
system is not leaking, a loss can come from the
coolant boiling through overheating and being
pushed out of the cooling system.

ZA WARNING
— The engine compartment in any vehicle can
be a dangerous area. Stop the engine and al-
low it to cool before working in the engine
compartment. Always follow the informa-
tion found in > page 203, General informa-
tion.
— Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment. This increases the risk of
burns. The cooling system is under pressure.
When you no longer see or hear steam or
coolant escaping, you may open the engine
compartment with caution.
— 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.
— The coolant additive and the coolant can be
dangerous to your health. For this reason,
keep the coolant in the original container
and away from children. There is a risk of
poisoning.

@) Note
Do not add coolant if the expansion tank is
empty. Air could 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 Service Facility for assis-
tance.

Battery
rae Le cel)
Because of the complex power supply, all work on
batteries such as disconnecting, replacing, etc.,
should only be performed by an authorized Audi
dealer or authorized Audi Service Facility > A.
Multiple batteries with different technologies
may be installed in your vehicle:
— Vehicle battery (for example, for starting the
engine, basic power supply) > page 213, Lead
battery or > page 213, Other battery types
— Auxiliary battery (for example, for recuperation
or optional equipment) > page 213, Other bat-
tery types
Not running the vehicle for long periods of
time
The battery will gradually drain if the vehicle
does not run for long periods of time. To ensure
that the vehicle can still be started, the electrical
equipment will be reduced or switched off
= page 87. Some convenience functions, such as
interior lighting or power seat adjustment, may
not be available under certain circumstances.
These convenience functions will be available
again once you switch the ignition on and start
the
engine.
Even when electrical equipment is switched off,
the equipment can still drain the battery if the
212
vehicle is not driven for long periods of time.
Deep draining results in a chemical reaction that
destroys the inside of the battery. The battery
must be charged every month to prevent this
= page 213. Contact an authorized Audi dealer or
authorized Audi Service Facility for more infor-
mation.
Winter operation
Cold weather places higher demands on the bat-
tery. This results in reduced starting ability. Have
the battery checked by an authorized Audi dealer
or authorized Audi Service Facility before cold
weather begins.

ZA\ WARNING
All work on the battery or electrical system in
your vehicle can result in injuries, chemical
burns, accidents, or burns. Because of this, all
work must be performed only by an author-
ized Audi dealer or authorized Audi Service Fa-
cility.

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.
>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 location
with as little exposure to light as
possible.

AN 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 acci-
dent because it can cause the
tire to burst.

216


—Always adapt your driving to
the road and traffic condi-
tions. Drive carefully and re-
duce your speed on icy or slip-
pery roads. Even winter tires
can lose traction on black ice.

() 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
and braking ability. If summer
tires are used in very cold tem-
peratures, 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.
