Fuel  supply 
Applies  to:  vehicles with  gaso line  engine 
Using  the  right  fuel  helps  keep  the  environment 
clean  and prevents  engine damage. 
Fuel  recommendation 
The fuel  recommended  for your vehicle  is unlead
ed  premium 
grade  gasoline . Audi recommends 
using  TOP TIER Detergent  Gasoline with  a mini
mum  octane  rating  of 91  AKI (95  RON). For more 
information  on TOP TIER Detergent  Gasoline, 
p lea se  go to  the offic ial website 
(www.toptiergas .com). 
The  recommended  gasoline  octane  rating  for 
your  engine  can also  be found  on  a label  located 
on the  ins ide of the  fuel filler flap . This  rating 
may  be specified  as  AKI or  RON. 
Your vehicle  may also  be operated  using  unlead
ed  regular  gasoline  with  a minimum  octane  rat
ing of  87 AKl/91  RON . However, using 87 AKI/91 
RON  octane  fuel wil l slightly  reduce  engine per
formance. 
Use unleaded  gasoline only. Unleaded  gasoline 
is availab le  throughout  the  USA, Canada,  and  in 
most  European  countries . We  recommend  that 
you  do  not  take  your vehicle to  areas  or  countries 
where  un leaded  gaso line may not  be  available. 
For  more  information  on  refueling  your vehicle, 
see 
¢page  199. 
Octane  rating 
Octane  rating  indicates a gasoline's  ability  to  re
sist  engine  damaging  "knock" caused  by prema
ture  ignit ion  and  detonation . Therefore,  buying 
the  correct  grade  of gasoline  is very  important  to 
he lp  prevent  possible  engine  damage  and  a  loss 
of  eng ine performance. 
Gasoline  most  commonly  used  in the  United 
States  and  Canada  has  the  following  octane  rat
i n gs  that  can  usually  be found  on  the  filler  pump: 
- Premium  Grade: 91  - 96  AKI 
198 
- Regular  Grade: 87  - 90  AKI 
Explanation  of the  abbreviations: 
AKI  = Anti  Knock  Index = (R +M)/2  = (RON +MON)/ 
2 
RON =  Research  Octane  Number 
MON=  Motor  Octane  Number. 
{[)  Note 
-Do not  use any fuel  with  octane  ratings  low
er  than  87  AKI or 91  RON otherwise  expen
sive engine  damage  wi ll occur . 
- Do 
not use  leaded  gasoline.  The use  of lead
ed  gasoline  will severely  damage  your  vehi
cle's  catalytic  converter  and  its  ability to 
control  exhaust  emissions . 
Blended  gasoline 
Applies  to:  vehicles with  gasoline  engine 
Use of gasoline  containing  alcohol  or MTBE 
(methyl  tertiary  butyl  ether) 
You may use  unleaded  gasoline  blended  with  al
cohol  or MTBE (commonly  referred  to  as  oxygen 
ates)  if  the  blended  mixture  meets the  following 
criteria: 
Blend of  gasoline  methanol  (wood alcohol  or 
methyl  alcohol) 
-Anti -knock index  must  be 87  AKI or  h igher. 
- Blend must  contain  no  more  than  3%  metha-
nol. 
- Blend must  contain  more  than  2%  co-solvents. 
Blend of  gasoline  and ethanol (grain alcohol  or 
ethyl  alcohol) 
- Anti-knock index  must  be 87  AKI or h igher . 
- Blend must  not contain  more  than  15%  etha-
nol. 
Blend of  gasoline  and MTBE 
-Anti-knock index  must  be 87  AK I or  higher . 
- Blend  must contain  not  mo re than  1S%  MTBE. 
Seasonally  adjusted  gasoline 
Many gasoline  grades  are  blended  to  perform  es
pecially well for  winter  or summer  dr iv ing . Dur-
i ng  seasonal  change-over,  we suggest  that  you  .,..  

Fuel  and  Refueling 
(D Note 
Never  drive  your  vehicle  until  the  fuel  tank  is 
completely  empty.  The  irregular  supply  of 
fuel  can  cause  misfiring.  Gasoline  could  enter 
the  exhaust  system  and  damage  the  catalytic 
converter . 
Refuelling 
Fig.  177 Right  rear  vehicle  side:  Opening  the  fuel  filler  flap 
Fig. 178 Fuel filler  flap w ith  attached  fuel cap 
When  activating  the  central  locking,  the  fuel  fill
er  flap  is automatically  unlocked  or  locked. Re
fuel  the  vehicle  with  the  ignition  switched 
off. 
Taking  the  fuel  cap  off 
..  Press  the  left  side  of the  fuel  filler  flap  to  open 
it 
9 fig. 177-arrow- . 
..  Unscrew  fuel  filler  cap  counter-clockwise  and 
hang  it  on  the  fuel  filler  flap¢ 
fig. 178. 
Refuelling  procedure 
.. Insert  the  fuel  nozzle  from  the  gasoline  pump 
into  the  fuel  filler  neck  as  far  as  it  will go. 
..  Select  a  medium  refuelling  rate  so  that  the 
nozzle  switches  off  automatically  when  the 
tank  is full. 
200 
Putting  the  fuel  cap  back  on 
..  After  filling  your  tank, twist the  fuel  filler cap 
clockwise  as  far  as  it  will go. 
..  Close  the  fuel  filler  flap. 
To avoid  fuel  spilling  or  evaporating  from  the  fuel 
tank  always  close  fuel  filler  cap  properly  and 
completely.  An improperly  closed  fuel  filler  cap 
may  also  cause  the  MIL  lamp ¢ 
page 28 to  come 
on. 
A WARNING 
Improper  refueling  or  handling  of fuel  can 
cause  fire,  explosion  and  severe  burns. -
- Fuel  is  highly  flammable  and  can  cause  se
vere  burns  and  other  injuries . 
- Failure  to  shut  the  engine  off  while  refuel
ing  and/or  to  insert  the  pump  nozzle  fully 
into  the  fuel  filler  neck  could  cause  fuel  to 
spray  out  of filler  neck  or to  overflow.  Fuel 
spray  and  overflowing  fuel  can  cause  a  fire. 
- Never  use  a  cellular  telephone  while  refuel
ing.  The  electromagnetic  radiation  can 
cause  sparks  that  can  ignite fuel  vapors  and 
cause  a fire. 
- Never  get  back  into your  vehicle  while  refu
eling. 
If in  exceptional  circumstances  you 
must  get  back  in your  vehicle  while  refuel
ing,  make  certain  that  you  close  the  door 
and  touch  metal  to  discharge static  electric
ity  before  touching  the  filler  nozzle  again. 
Static  electricity  can  cause  sparks  that  can 
ignite  fuel  vapors  released  during  refueling. 
- Never  smoke  or  have  an  open  flame  any
where  in  or  near  your  vehicle  when  refueling 
or filling  a  portable  fuel container  . 
- For  your  safety,  we  strongly  recommend 
that  you  do  not  travel  with  a  portable  fuel 
container  in your  vehicle.  The  container,  full 
or  empty  may  leak  and  could  cause  a  fire, 
especially  in a  crash . 
- If,  under  exceptional  circumstances,  you 
must  transport  a  portable  fuel  container, 
please  observe  the  following: 
- Never  fill  a  portable  fuel  container while  it 
is  anywhere  in or  on  the vehicle  (for  exam
ple,  in  the  luggage  compartment,  or  on 
the  trunk).  Static  electricity  can  build  up
