Checking and Filling
Refueling
Fueling procedure
Fig. 254 Right re ar side of the vehicle : opening the fue l
filler door
Fig. 255 Fu el fi lle r door w it h atta ched fuel cap
The fuel f ille r door is unlocked or locked by the
central locking system .
• Press on the left side of the fuel filler door to
open
c:!;> fig. 254.
• Unscrew the tank cap counterclockw ise.
• Place the cap from above on the open fue l filler
door c:!;>fig. 255.
• Insert the fu el pump no zz le all the way into th e
fuel filler neck.
• Begin fueling . Once the fuel pump noz zle turns
off the first time, the fuel tank is full. Do not continue fueling , or else the expans ion space in
the tank will be filled with fuel.
• After the fuel pump has switched off , wait five
seconds before remov ing it to allow the rest of
the fuel to f inish dripp ing into the fuel tank.
• Turn the fue l cap clockwise until you hear it
lock.
• Close the fuel filler door and then pr ess on th e
left side until it latches.
The correct fu el type for your vehicle can be
found on a lab el located on the inside of the fue l
312
filler door. For additional information on fuel,
se e
c:!;> page 310.
For the tank capacity in your veh icle, refer to the
Technica l Data
c:!;> page 3 75 .
To reduce the risk of fuel leaking out or vapors
escaping, make sure that the fuel tank is closed
correctly. Otherw ise the
¢'4 ind icator light wi ll
turn on.
If the cent ral locking system malfunctions , the
fuel filler doo r may emergency re lease
c:!;> page 314.
& WARNING
An improper fueling procedure and improper
handling of fuel can lead to explosions, fires,
severe burns and other in juries.
- Do not smoke and keep away from open
flames.
- The ignition must be sw itched off when re­
fueling.
- Cell phones, radio devices and other rad io
equipment should a lways be switched off
when refueling. E lectromagnetic 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 the
vehicle must be entered, close the door and
touch a metal surface before touching the
fuel pump nozzle again . This will reduce the
r isk of electrostatic discharge that can cause
f lying sparks. Sparks can start a fire when
refueling.
& WARNING
We recommend that you do not transpo rt any
f u el containers in the vehicle . Fuel could leak
out of the container and ignite, especially dur­
ing an accident. This can cause explosions,
fires and injuries.
- If you must transport fuel in a fuel contain­ er, p lease note the following :

Checking and Filling
If the indicator light does not turn off, drive im­
mediately to an authorized Audi dea ler or author­
ized Audi Service Fac ility to have the malfunction

high, both whe n driving and after stopping
the engine .
- Never touch the exhaust ta il pipes once they
have become hot. This could result in burns .
- Do not park you r vehicle over flammable
materials such as g rass or leaves because
the h igh temperat ure of the emiss ions con­
t rol sys tem cou ld start a f ire.
- Do not apply underbody p rotectant in the
exha ust system a rea, because this increases
the risk of fire.
- Applies to: vehicles wi th diesel particulate
filte r: always adjus t your speed to the
weathe r, road, te rra in and traffic con ditio ns
dur ing diesel partic ulate fi lter regene ration.
Yo u should never disobey tra ffic laws in or­
der to fo llow dr iv ing recommendations.
(D Tips
Applies to: ve hicles with diesel particulate filter
- Due to the high temperatures that occur
d uring diesel pa rticu late filter regenerat ion,
the radiator fan may continue runn ing after
the engine stops, even if the engine did not reach its operat ing temperatu re.
- Noises, odors and increased speeds may oc­
cur d uring the regeneration.
- Always use the co rrect engine oil and fuel to
ens ure that the serv ice life of the d iesel par­
ticulate filter is not reduced.

Checking and Filling
- Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the State of Cali­
forn ia to cause cancer and birth defects and
reproduct ive harm . In addition, certain flu­
ids contained in veh icles and certain prod­
ucts of compo nent wear contain or emit
chemicals known to the State of California
to cause cancer and birth defects or other reproductive harm .
- Battery posts, termina ls and related acces­
sories contain lead and lead compounds, chemicals known to the State of California
to cause cancer and reproductive harms.
Wash hands after handling .
(D Note
When filling flu ids, be sure not to mix the flu ­
ids up . Otherwise severe ma lfunctions and en­
gine damage w ill occur .
@ For the sake of the environment
You shou ld regularly check the ground under
your vehicle in order to detect leaks quickly. If
there are visible spots from oil or other fluids,
bring your vehicle to an authorized Audi deal­

not latched increases the r isk of an accident . ..,.

Check ing and F illing
Detergent additives in the oil will make fresh oi l
look dark after the engine has been running for a
short t ime. Th is is norma l and is not a reason to
change the oil more often than recommended.
Because of the prob lem of p roper disposa l, along
with the special tools and necessary expertise re­
qu ired, we strongly recommend that you have
your oil changed by an authorized
Audi dealer or
