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.

C) Note
If the engine oil level is too low or too high,
there is a risk of engine damage.
G) Tips
The oil level indicator in the display is only an
informational display. If the oil level is too
low, a minimum oil warning appears in the in-
strument cluster. Add oil and close the engine
compartment lid. The current oil level is dis-
played in the Infotainment system the next
time the ignition is switched on.
G) Tips
— The engine oil consumption may be up to
1 quart per 600 miles (0.8 liter/1,000 km),
depending on driving style and operating
conditions. Consumption may be higher dur-
ing the first 3,000 miles (5,000 km). The
engine oil level must be checked regularly.
It is best to check each time you refuel your
vehicle and before long drives.
— Because of the lubrication and cooling of
the engine, combustion engines consume
oil. The oil consumption varies depending
on the engine and may change during the
service life of the engine. Engines generally
consume more oil at the beginning during
the break-in period. Then oil consumption
stabilizes after the break-in period.
— Under normal conditions, oil consumption
depends on the quality and viscosity of the
oil, the engine RPM, the climate conditions,
and the road conditions. The dilution of oil
from condensation or fuel residue as well as
the age of the oil also play a role. Because
engine wear increases with mileage, oil con-
sumption will increase again over time until
it may be necessary to replace worn compo-
nents.
— Because all these variables play a role, it is
not possible to define an oil consumption
standard. Therefore, the oil level must be
checked regularly.

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
