as possible, before installing the forward-
facing child restraint.
— Always make sure that the safety belt upper
anchorage is behind the child restraint and
not next to or in front of the child restraint
so that the safety belt will be properly posi-
tioned.
— Always make sure that nothing prevents the
front passenger's seat from being moved to
the rearmost position in its fore and aft ad-
justment range.
— Always make sure the backrest is in an up-
right position.
— Never place or use any electrical device
(such as a laptop, CD player, electronic
games device, power inverter or seat heater
for child seats) on the front passenger seat
if the device is connected to the 12-volt
socket or the cigarette lighter socket.
— If a seat heater has been retrofitted or oth-
erwise added to the front passenger seat,
never install any child restraint system on
this seat.
— Make sure that there are no wet objects
(such as a wet towel) and no water or other
liquids on the front passenger seat cushion.
— Never place objects on the seat (such as a
laptop, CD player, electronic games device,
power inverter or seat heater for child
seats). These may influence the electrical
capacitance measured by the capacitive pas-
senger detection system and can also fly
around in an accident and cause serious per-
sonal injury.
— Make sure that the PASSENGER AIR BAG
OFF light comes on and stays on all the time
whenever the ignition is switched on.
— If the PASSENGER AIR BAG OFF light does
not come on and stay on, immediately in-
stall the forward-facing child seat at a seat-
ing position on the rear seat and have the
airbag system inspected by your authorized
Audi dealer.
— Take the child restraint off the front passen-
ger seat and install it properly at one of the
rear seat positions if the PASSENGER AIR
BAG OFF light does not stay on whenever
the ignition is switched on.

Booster seats and safety belts
Properly used booster seats can help protect
children weighing between about 40 lbs. and 80
lbs. (18 kg and 36 kg) who are less than 4 ft. 9
in. (57 inches/1.45 meters) tall.

Fig. 230 Rear seat: child properly restrained in a booster
seat
The vehicle's safety belts alone will not fit most
children until they are at least 4 ft. 9 in. (57 in-
ches/1.45 meters) tall and weigh about 80 lbs.
(36 kg). Booster seats raise these children up so
that the safety belt will pass properly over the
stronger parts of their bodies and the safety belt
can help protect them in a crash.
> Do not use the convertible locking retractor
when using the vehicle's safety belt to restrain
a child on a booster seat.
> The shoulder belt must lie as close to the cen-
ter of the child's collar bone as possible and
must lie flat and snug on the upper body. It
must never lie across the throat or neck. The
lap belt must lie across the pelvis and never
across the stomach or abdomen. Make sure the
belt lies flat and snug. Pull on the belt to tight-
en if necessary.
> Applies to: vehicles with safety belt height ad-
justment: If you must transport an older child
in a booster seat on the front passenger seat,
you can use the safety belt height adjustment
to help adjust the shoulder portion properly.
> Secure unused safety belts on the rear seat
=> page 284.
Children up to at least 8 years old (over 40 Lbs or
18 kg) are best protected in child safety seats de-
signed for their age and weight. Experts say that

retractor:
> Place the child restraint on a seat, preferably on
the rear seat.
> Slowly pull the belt all the way out.
> Route it around or through the child restraint
belt path > A\.
» Push the child safety seat down with your full
weight to get the safety belt really tight.
> Insert the belt tongue into the buckle for that
seating position.
> Guide the safety belt back into the retractor un-
til the belt lies flat and snug on the child safety
seat.
> You should hear a “clicking” noise as the belt
winds back into the inertia reel. Test the con-
vertible locking retractor by pulling on the belt.
You should no longer be able to pull the belt
out of the retractor. The convertible locking re-
tractor is now activated.
> Make sure that the red release button is facing
away from the child restraint so that it can be
unbuckled quickly.
> Pull on the belt to make sure the safety belt is
properly tight and fastened so that the seat
cannot move forward or sideways more than
one inch (2.5 cm).

ZA WARNING
Using the wrong child restraint or an improp-
erly installed child restraint can cause serious
personal injury or death in a crash.
— Always make sure that the safety belt retrac-
tor is locked when installing a child safety
seat. An unlocked safety belt retractor can-
not hold the child safety seat in place during
normal driving or in a crash.
— Always buckle the child safety seat firmly in
place even if a child is not sitting in it. A
loose child safety seat can fly around during
a sudden stop or ina crash.
— Always make sure the seat backrest to which
the child restraint is installed is in an up-
right position and securely latched into
place and cannot fold forward. Otherwise,
the seatback with the child safety seat at-


tached to it could fly forward in the event of
an accident or other emergency situation.
— Always read and heed all WARNINGS when-
ever using a child restrained in a vehicle is
being used > page 278. Special precautions
apply when installing a child safety seat on
the front passenger seat > page 254, Child
restraints on the front seat - some impor-
tant things to know.
Deactivating the convertible locking
retractor
The convertible locking retractor for child re-
straints will be deactivated automatically when
the belt is wound all the way back into the re-
tractor.


>» Press the red button on the safety belt buckle.
The belt tongue will pop out of the buckle.
> Guide the safety belt all the way back into its
stowed position.
Always let the safety belt retract completely into
its stowed position. The safety belt can now be
used as an ordinary safety belt without the con-
vertible locking retractor for child restraints.
If the convertible locking retractor should be ac-
tivated inadvertently, the safety belt must be un-
fastened and guided completely back into its
stowed position to deactivate this feature. If the
convertible locking retractor is not deactivated,
the safety belt will gradually become tighter and
uncomfortable to wear.

ZA WARNING
Improperly installed child safety seats in-
crease the risk of serious personal injury and
death ina collision.
— Never unfasten the safety belt to deactivate
the convertible locking retractor for child re-
straints while the vehicle is moving. You
would not be restrained and could be seri-
ously injured in an accident.

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.

installed accessories, a full tank
of fuel, oil, coolant and other flu-
ids plus maximum load. The max-
imum Load includes the number
of passengers that the vehicle is
intended to carry (“seating ca-
pacity”) with an assumed weight
of 150 lbs. (68 kg) for each pas-
senger at a designated seating
position 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 included 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-
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.
The Gross Vehicle Weight Rating
and the Gross Axle Weight Rating
are listed on the safety compli-
ance sticker label located on the
driver’s side B-pillar.

Z\, 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 in-
crease 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.
—Tires ona vehicle that has
been overloaded can fail sud-
denly, including a blowout and
sudden deflation, causing loss
of control and a crash.
—Always make sure that the to-
tal load being transported -
including the weight of a trail-
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle

Gross Vehicle Weight Rating.
Determining correct load
Tani
Use the example below to calcu-
late the total weight of the pas-
sengers and luggage or other
things that you plan to transport
so that you can make sure that
your vehicle will not be overload-
ed.


Steps for Determining Correct
Load Limit
1. Locate the statement “THE
COMBINED WEIGHT OF OCCU-
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS” on your vehicle’s placard
(tire inflation pressure label)
=> page 330, fig. 259.
2. Determine the combined
weight of the driver and pas-
sengers that will be riding in
your vehicle.
3. Subtract the combined weight
of the driver and passengers
from “XXX” kilograms or “XXX”
pounds shown on the sticker
=> page 330, fig. 259.
4. The resulting figure equals the
available amount of cargo and
334
luggage load capacity. For ex-
ample, if the “XXX” amount
equals 1400 lbs. and there will
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)
5. Determine the combined
weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely ex-
ceed the available cargo and
luggage load capacity calculat-
ed in Step 4.
6. If your vehicle will be towing a
trailer, load from your trailer
will be transferred to your vehi-
cle. Consult this manual to de-
termine how this reduces the
available cargo and luggage
load capacity of your vehicle.
> Check the tire sidewall
(=> page 320, fig. 257) to deter-
mine the designated load rating
for a specific tire.

stored. Refer to the tire pressure label for the
recommended tire pressure for your vehicle
=> page 330, fig. 260.
Tire tread circumference and vibration character-
istics can change and cause a tire pressure warn-
ing if:
— The tire pressure in one or more tires is too low
—The tire has structural damage
— The tire was replaced or the tire pressure was
changed and it was not stored > page 338
— One side of the vehicle is more heavily loaded
than the other
— The wheels on one axle are more heavily loaded
than the others (for example, when towing a
trailer or when driving up and down hills)
— Snow chains are installed
— The spare tire* is installed
— Only one tire was replaced on each axle

ZX WARNING
— If the tire pressure indicator appears in the
instrument cluster display, reduce your
speed immediately and avoid any hard steer-
ing or braking maneuvers. Stop as soon as
possible and check the tires and their pres-
sures.

— The driver is responsible for maintaining the
correct tire pressures. You must check the
tire pressures regularly.
— Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
be delayed.
— Do not use run-flat tires on your vehicle. Us-
ing them when not permitted can lead to ve-
hicle damage or accidents.
(i) Tips
—The tire pressure monitoring system can al-
so stop working when there is an ESC/ABS
malfunction.

— Using snow chains may result in a system
malfunction.
— The tire pressure monitoring system in your
Audi was calibrated with “Audi Original
Tires” > page 326. Using these tires is rec-
ommended.
—The tire pressure monitoring system can on-
ly monitor the tire pressure of the driving
tires. Check the tire pressure of the spare
wheel in the luggage compartment so that
if necessary it is ready for use.
Storing tire pressures
Applies to: vehicles with Tire Pressure Monitoring System in-
dicator
A change in tire pressure or a change in tires
must be stored in the system.
Before storing the tire pressures, make sure the
tire pressures in all four tires meet the specified
values and are adapted to the load > page 328.

> Select in the Infotainment system: [MENU] but-
ton > Vehicle > left control button > Service &
checks > Tire pressure monitoring > Store tire

Care and cleaning

Care and cleaning
General information
Regular, proper care helps to maintain your vehi-
cle's value. It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The required cleaning and care products can be
obtained from an authorized Audi dealer or au-
thorized Service Facility. Read and follow the in-
structions for use on the packaging.

ZA WARNING
— Using cleaning and care products incorrectly
can be dangerous to your health.
— Always store cleaning and care products out
of reach of children to reduce the risk of poi-

soning.

@ For the sake of the environment
— Purchase environmentally-friendly cleaning
products if possible.
— Do not dispose of cleaning and care prod-
ucts with household trash.
Car washes
The longer that deposits such as insects, bird
droppings, tree sap or road salt remain on the ve-
hicle, the more the surface can be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a
microfiber cloth.
Also, wash the underside of your vehicle once
road salt stops being used for the season.
Pressure washers
When washing your vehicle with a pressure wash-
er, always follow the operating instructions pro-
vided with the pressure washer. This is especially
important in regard to the pressure and spraying
distance. Do not aim the spray directly at seals on
342
side windows, doors, the hood, the luggage com-
partment lid, or the panoramic glass roof* or at
tires, rubber hoses, insulating material, the pow-
er top*, sensors*, or camera lenses*. Keep a dis-
tance of at least 16 in (40 cm).
Plug-in hybrid drive: do not direct the stream of
water towards the wall mount clip*.
Do not remove snow and ice with a pressure
washer.
Never use cone nozzles or high pressure nozzles.
The water temperature must not be above 140 °F
(60 °C).
Automatic car wash
Spray off the vehicle before washing.
Make sure that the windows, the panoramic glass
roof*, and the power top” are closed and the
windshield wipers are off. Follow instructions
from the car wash operator, especially if there are
accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work-
ing downward using a soft sponge or cleaning
brush. Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To reduce the risk of damaging the paint when
washing, first remove dust and large particles
from your vehicle. Insects, grease spots, and fin-
gerprints are best removed with a special cleaner
for matte finish paint.
Apply the product using a microfiber cloth. To re-
duce the risk of damaging the paint surface, do
not use too much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft micro-
fiber cloth.
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a chamois. >
