Checking and Filling

> Check the coolant level in the coolant expan-
sion tank > page 307, fig. 248 using the outer
markings (2) > fig. 252. The coolant level must
be between the markings (2) when the engine is
cold. When the engine is warm it can be slight-
ly above the upper marking.
Adding coolant
Applies to: vehicles with plug-in hybrid drive:
Your vehicle has two coolant expansion tanks
that are separate from each other. The smaller of
the two expansion tanks must not be opened
= page 312. Read and follow the important safe-
ty precautions > A\ in Coolant on page 312.
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.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cover.
> Remove the cover (@) © fig. 252 carefully to the
left > AX.
» Add the correct mixture ratio of coolant
> page 311 up to the upper marking @
> fig. 252.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Close the cap securely.
Coolant loss usually indicates that there is a leak.
Immediately drive your vehicle to an authorized
Audi dealer or authorized Audi Service Facility
and have the cooling system inspected. If the
cooling system is not leaking, coolant loss can re-
sult from the coolant boiling due overheating
and then being forced out of the cooling system.

— 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.
— Coolant additive and coolant can be danger-
ous to your health. For this reason, store 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.

ish decorative decals that have a matte or
printed finish.

ice scraper to remove snow and ice on win-
dows with decorative decals on them.
— Displays and instrument cluster

trim surrounding them must not be
cleaned with dry cleaning methods be-
cause they could be scratched.
— Make sure that the instrument cluster is
switched off and has cooled off before

Care and cleaning

—If there is damage to the webbing, the
connections, the retractors, or the buck-
les, have them replaced by an authorized
Audi dealer or authorized Audi Service Fa-
cility.
— Textiles, artificial leather, and Alcantara
— Never treat artificial leather or Alcantara
with leather care products, solvents, floor
polish, shoe polish, spot remover, or simi-
lar products.
— Have a cleaning specialist remove stub-
born stains to reduce the risk of damage.
— Never use steam cleaners, brushes, hard
sponges, etc. when cleaning.
— Do not turn on the seat heating* to dry
the seat.
— Objects with sharp edges, such as zippers
or rivets on clothing or belts, can cause
damage to the surface.
— Open hook and loop fasteners, for exam-
ple on clothing, can damage seat covers.
Make sure hook and loop fasteners are
closed.
— Natural leather
— Never treat leather with solvents, floor
polish, shoe polish, spot remover or simi-
lar products.
— Objects with sharp edges, such as zippers
or rivets on clothing or belts, can cause
damage to the surface.
— Never use steam cleaners, brushes, hard
sponges, etc. when cleaning.
— Do not turn on the seat heating* to dry
the seat.
—To help prevent the leather from fading,
do not leave the vehicle in direct sunlight
for long periods of time. If leaving the ve-
hicle parked for long periods of time, you
should cover the leather to protect it from
direct sunlight.
— Wall mount clip
— Do not us any abrasive cleaning products
or any that contain alcohol, because these
increase the risk of discoloration.
@) Tips
— Insects are easier to remove from paint that
has been freshly waxed.
— Regular waxing can prevent rust spots from
forming.
— Decorative decals can age due to environ-
mental conditions, which can result in dam-
age such as brittleness. The color may fade
if exposed to excessive sunlight.

of service
If you would like to take your vehicle out of serv-
ice for a long period of time, contact an author-
ized Audi dealer or authorized Audi Service Facili-
ty. They will advise you of important measures,
such as corrosion protection, service, and storage
