Checking and Filling

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.
— If the G12evo coolant additive is not availa-
ble in an emergency, do not add any other
additive. You could damage the engine. If
this happens, only use distilled water and
restore 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.
— You can continue driving if the permitted
G12evo coolant additive was not added.
However, go to an authorized Audi dealer or
authorized Audi Service Facility immediately
to have the coolant replaced to reduce the
risk of engine damage.
— Due to the risk of engine damage, the cool-
ing system should only be refilled by an au-
thorized Audi dealer or authorized Audi
Service Facility. An authorized Audi dealer or
authorized Audi Service Facility can also pro-
vide you with important information about
the recommended coolant additive.

Checking the coolant level
> Park the vehicle on a level surface.
> Switch the ignition off.
> Open the hood > page 231.
The coolant expansion tank for some engines is
located in the water drip tray under a cover. If
necessary, remove the cover that is located under
the windshield wiper on the front passenger's
side.
> Check the coolant level in the coolant expan-
sion tank > page 232, fig. 167 using the outer
markings (2) > fig. 169. 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.
> Applies to: vehicles with 6-cylinder engine:
There is a float located in the coolant expansion
tank. Read the coolant level using the coolant
level float. When the engine is cold, the float
must be located between the MIN marking and
the edge of the filler opening on the coolant ex-
pansion tank.
> When you add coolant to the expansion tank,
please refer to > page 236, Cooling system.
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. Audi recommends mixing
the coolant additive with distilled water.
> Allow the engine to cool.
> Place a large, thick towel on the coolant expan-
sion tank cap.
> Push the release button @) > fig. 169 on the
cap and carefully turn it to the left until you
feel resistance > /\.
> Push the release button again and remove the
cap completely.
» Add coolant in the correct mixture ratio
=> page 236 up to the MAX marking. Or, in
vehicles with a 6-cylinder gasoline engine, the
float must be located between the MIN mark-
ing and the edge of the filler opening on the
coolant expansion tank.
> Make sure that the fluid level remains stable.
Add more coolant if necessary.
> Vehicles with 6-cylinder engine: if necessary,
press the float into the coolant expansion tank
using the cover.
> Turn the cap to the right to tighten it until you
feel resistance a second time.

Care and cleaning

— Paint
—To reduce the risk of scratches, the vehicle
must be free of dirt and dust before pol-
ishing or waxing.
—To prevent paint damage, do not polish or
wax the vehicle in direct sunlight.
—To reduce the risk of paint damage, do not
polish away rust spots.
— Remove cosmetics and sunscreen immedi-
ately because they could damage the
paint.
— Decorative decals
—To reduce the risk of damage, do not use
any rough powder or abrasive cleaning
products.
—To reduce the risk of damage, do not pol-
ish decorative decals that have a matte or
printed finish.
— Due to the risk of damage, do not use an
ice scraper to remove snow and ice on win-
dows with decorative decals on them.
— Displays and instrument cluster
— Make sure that the display and instrument
cluster are switched off and have cooled
down before cleaning. To switch off the
center display, select on the MMI home
screen: SETTINGS > Display & brightness
> MMI > Screen cleaning.
— Displays, the instrument cluster, and the
trim surrounding it must not be cleaned
with dry cleaning methods because they
could become scratched.
— Make sure no fluids enter the spaces be-
tween the instrument cluster and the
trim, because that could cause damage.
— Controls
— Make sure that no fluids enter the con-
trols, because this could cause damage.
— Safety belts
— Do not remove the safety belts to clean
them.
— Never clean safety belts or their compo-
nents with chemicals or with corrosive flu-
ids or solvents and never allow sharp ob-
jects to come into contact with the safety
belts. This could cause damage to the belt
webbing.
272
— 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-

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.
G) Tips
— Insects are easier to remove from paint that
has been freshly waxed.
— Regular waxing can prevent rust spots from
forming.

Emergency assistance

(50 km), then transport the vehicle on a
special carrier.
— If the vehicle is towed by a tow truck at the
axle that is not permitted, this can cause se-
vere damage to the transmission.
— The vehicle must not be tow started for
technical reasons.
@® Tips
— If the power supply is interrupted, then it
will not be possible to move the selector
lever out of the "P" position. The parking
lock must be released using the emergency
release before towing the vehicle
=> page 108.
— Switch Audi pre sense* off > page 155 when
loading the vehicle onto a vehicle carrier,
train, ship, or other type of transportation,
or when towing the vehicle. This can prevent
an undesired intervention from the pre
sense* system.
— Follow the local legal regulations for tow-
ing.
Read and follow the important information under
=> page 282.
Preparations
> Only secure the towing cable or tow bar at the
designated towing loop > page 283.
> Make sure the towing cable is not twisted. Oth-
erwise it could disconnect from the towing loop
while towing.
> Switch the emergency flashers on in both
vehicles > page 61. However, do not do this if it
prohibited by law.
Towing vehicle (front)
> Only start to drive when the towing cable is
taut.
> Press the brake pedal very carefully.
» Avoid sudden braking or driving maneuvers.
Vehicle being towed (rear)
> Make sure the ignition is switched on so that
the steering wheel is not locked and so that you

can use the turn signals, the horn, and the
windshield wipers if needed > A\.
> Switching it off before the vehicle has stopped
may
impair the function of the brake booster
and power steering. You would then need to
use more force to steer and brake the vehicle.
> Release the parking brake > page 114.
> Select the “N” selector lever position.
> Make sure the towing cable is always taut.

JN WARNING
— Never tow a vehicle using a tow bar or tow-
ing cable if the vehicle does not have electri-
cal power.
