Checking and Filling

The correct fuel type for your vehicle can be
found ona label located on the inside of the fuel
filler door. For additional information on fuel, see
=> page 226.
For the tank capacity in your vehicle, refer to the
Technical Data > page 290.

ZA\ WARNING
Improper fueling procedures and improper
handling of fuel can lead to explosions, fires,
severe burns, and other injuries.
— Do not smoke. Keep away from open flames.
— The ignition must be switched off when re-
fueling.
— Mobile devices, radio devices, and other ra-
dio equipment should always be switched
off when refueling. Electromagnetic rays
could cause sparks and start a fire.
— If you do not insert the fuel pump nozzle all
the way into the filler tube, then fuel can
leak out. Spilled fuel can ignite and start a
fire.
— Never get into the vehicle when refueling. If
there is an exceptional situation where you
must enter the vehicle, close the door and
touch a metal surface before touching the
fuel pump nozzle again. This will reduce the
risk of electrostatic discharge that can cause
flying sparks. Sparks can start a fire when
refueling.

ZA WARNING
The vehicle must not be refueled with a re-
serve canister due to the risk of fire.


@) Note
— Remove fuel that has overflowed onto any
vehicle components immediately to reduce
the risk of damage to the vehicle.
— Never drive until the fuel tank is completely
empty. The irregular supply of fuel that re-
sults from that can cause engine misfires.
Uncombusted fuel may enter the exhaust
system and increase the risk of damage to
the catalytic converter.
228
— Never insert any portable nozzles, funnels
or after-market containers into the fuel fill-
er neck.
— Do not pry open the fuel filler neck forceful-
ly or press against it with foreign objects to
open the tank system.
@) For the sake of the environment
— Do not overfill the fuel tank, or fuel could
leak out when the vehicle is warming up.
— Fuel should never enter the sewer system or
come into contact with the ground.
@ Tips
— If adverse weather conditions cause the fuel
filler door to freeze shut, press on the cen-
ter of the filler door with the heel of your
hand and then try opening it again.
— The fuel filler door on your vehicle does not
lock if you lock the vehicle from the inside
using the central locking switch.
@) Tips
— Your vehicle is equipped with a misfueling
guard. It allows the vehicle to be fueled only
with the correct fuel pump nozzle.
—Aworn or damaged nozzle or a nozzle that
is too small may not be able to open the die-
sel misfueling guard. If this is the case, try
turning the nozzle before inserting it in the
fuel filler neck, use a different fuel pump, or
see an authorized Audi dealer or authorized
Audi Service Facility for assistance.

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

@) 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.
— 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.
@ Tips
In certain weather conditions, water can
evaporate on the radiator and exit the side
vents as steam after stopping the engine.
Adding coolant
Applies to: vehicles without power top

st SN
S QD < a


Fig. 183 Engine compartment: markings on the coolant
expansion tank
Observe the safety precautions > page 229, Gen-
eral information.
Checking the engine coolant level
>» Park the vehicle on a level surface.
>» Switch the ignition off.
> Allow the engine to cool.
> Place a large, thick cloth over the coolant ex-
pansion tank cap and unscrew the cap counter-
clockwise > A\.
> Read the coolant level using the coolant level
float. The coolant level float may only stick out
over the edge of the coolant expansion tank a
maximum of 0.39 in (1 cm) when the engine is
cool.
Adding coolant
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coolant additive
with distilled water is recommended.
> Add coolant in the correct mixture ratio
=> page 236 until the dipstick is no more than
0.39 in (1 cm) above the edge of the coolant
expansion tank.
> 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.

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 229, General informa-
tion.
— Never open the engine compartment lid if
you can see or hear steam or coolant escap-
ing from the engine compartment. This in-
creases 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. |>

Wheels


AN WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla-
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.

ZA\ WARNING
Temperature grades apply to tires that are
properly inflated and not over or underinflat-
ed.

Tire pressure monitoring
system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat-
ed to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your vehicle has
tires of a different size than the size indicated on
the vehicle placard or tire inflation pressure la-
bel, you should determine the proper tire infla-
tion pressure for those tires).
As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS)
that illuminates a low tire pressure tell-
tale when one or more of your tires is significant-
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
check your tires as soon as possible, and inflate
them to the proper pressure. Driving ona signifi-
cantly under-inflated tire causes the tire to over-
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop-
ping ability.
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re-
sponsibility to maintain correct tire pressure,
even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres-
sure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the sys-
tem is not operating properly. The TPMS mal-
function indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for approxi-
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the mal-
function exists.
When the malfunction indicator is illuminated,
the system may not be able to detect or signal
low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
Applies to: vehicles with tire pressure monitoring system
The tire pressure monitoring system monitors
the pressure in the four tires when driving.
The system uses sensors that measure the tem-
perature and pressure in the tires. The data is
sent from these sensors to the control module by
radio frequency.
The tire pressure monitoring system shows the
current pressures and temperatures of the tires
in the Infotainment system while driving
=> page 262. It also compares the current tire
pressures with the stored tire pressures and gives
a warning if the tire pressure is different from
what is stored > page 262.
The system does not detect if the stored tire
pressures match the recommended tire pres-
sures. You must store the tire pressures again in
each of the following situations > page 263:
— Each time the tire pressures change, for exam-
ple when the load in the vehicle changes
— After replacing a 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 necessary care products can be obtained
from an authorized Audi dealer or authorized Au-
di Service Facility. Read and follow the instruc-
tions 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 remain on the vehicle,
the more the surface may 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 anda
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 direct the stream of water di-
rectly onto seals for the side windows, doors, lug-
gage compartment lid or engine compartment
lid, or onto the tires, rubber hoses, insulating
material, sensors” or camera lenses”. Keep a dis-
tance of at least 16 in (40 cm).
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 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.
Only use car washes where the vehicle remains
stationary and the washing equipment moves
around the vehicle when washing and drying. Car
washes that move the vehicle through the car
wash using a chain are not recommended.
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.

the
drained battery.
> If the engine does not start: Stop the starting
procedure after 10 seconds and then repeat it
after approximately 30 seconds.
> Turn on the rear window defogger in your vehi-
cle in order to reduce any voltage peaks that
may occur when disconnecting the jump start
cables. The headlights must be switched off.
> With the engines running, remove the cables in
reverse order of the way they were installed.
> Close the cover.

ZX WARNING
— Do not touch the non-insulated parts of the
terminal clamps. The cable must also not
come into contact with vehicle components
that conduct electricity when it is connected
to the positive vehicle battery terminal. This
can cause a short circuit.

278

—The locking bolts on the battery cells must
be tightened securely.
— Keep ignition sources (open flames, burning
cigarettes, etc.) away from the vehicle bat-
teries to reduce the risk of an explosion.
— If you jump start another vehicle, route the
jump start cable so that it does not become
caught in moving components in the other
vehicle's engine compartment.
@) Note
Please note that the connecting process previ-
ously described for the jump start cables is in-
tended for when your vehicle is being jump
started. If you are jump starting another vehi-
cle, connect the negative cable (-) to a large
metal component that is bolted securely to
the engine block, or to the engine block itself.
If the vehicle battery in the vehicle being
jump started is not vented to the outside,
there is a risk of explosion due to hydrogen
gas.
G) Tips
Make sure that the connected jump start ca-
bles have sufficient contact with metal.
