Single-trip memory (Trip computer 1)
The single -trip memory stores the trip infor­
mat ion from the time the ignition is turned on
until it is turned off. If the trip is continued
within 2 hours from the time the ignition was
turned off, the new data will be included in
the calculation of the current trip informa­
tion. If the trip is interrupted for
more than 2
hours the memory is reset automatically.
Total-trip memory (Trip computer 2)
Unlike the sing le-trip memory, the total-trip
memory is not reset automatically. This per­
mits you to evaluate your driving data for the
enti re pe riod between manual resets.

Fuel recommendation
The fuel recommended for you r vehicle is un ­
l e aded premium
g rade gasoline. A udi recom­
mends using TOP TIER De tergent Gaso line
w ith a m inimum octane ra ting of 91 A KI (95
RON) . Fo r more informa tion on TOP TIER De­
tergent Gasoline, please go to the off ic ial
website (www.toptie rgas .com) .
The re commended gasoline octane rating for
your eng ine can also be fo und o n a label loca t­
ed on t he ins ide of the fuel filler flap . This ra t­
ing may be specif ied as AKI or RO N.
Your veh icle may also be operated using un ­
l e aded regular g asoline w ith a min imum o c­
tane rating of 87 AKI/91 RO N. However, using
87 AK I/91 RON octa ne fue l w ill sli ghtly re­
d uce eng ine perfo rmance .
Use unleaded ga solin e only. Unleaded g aso­
line is available th rougho ut the USA, Ca nada,
and i n most E uropean countries . We recom­
mend that you do not ta ke yo ur vehicle to
areas or co untries where unleaded gasoline
may not be ava ilable.

Octane rating
Octane rati ng ind icates a gaso line's abili ty to

p remature ign ition and detona tion. Therefore,
buying the correct grade of gaso line is very
i mportant to he lp prevent possible engine
damage and a loss o f engine performance .
Gasoline mos t common ly used in the Unite d
States an d Canada has the following octane
ratings that ca n usually be fo und on the filler
pump :
Fuel supply and filling your fuel tank 207
-Premium Grade: 9 1 -96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abb reviations :
AKI = Anti Knock Index = (R+ M)/2 = (RO N
+ MON)/2
RON = Research Octane Num ber
MON= Motor Octane Number.
@ Note
- Do not use a ny fue l w ith octane rat ings
lower than 87 AKI or 9 1 RO N othe rwise

- Do
not use leaded gasoli ne. The use of

Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether )
You may use unleaded gasoline blende d with
alcohol or MTB E (commonly referred to as
oxygenates) if the blended m ixture meets the
fo llow ing criter ia:
Blend of gasoline methanol (wood alcohol or
methyl alcohol )
-Anti -knoc k index mus t be 87 A KI or higher.
- Blend mus t contain no more t han 3% me th -
a nol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15%

off.
Taking the fuel cap off
~Turnoff the ignition .
~ Press the left side of the fuel filler flap to
open it
c::> fig. 176 -arrow- .
~ Unscrew fuel cap counter-clockwise and
hang it on the fuel filler flap
~ fig. 177.
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 a utomatica lly when the
tank is full.
Putting the fuel cap back on
~ After filling your tank, tw ist the fuel cap
clockwise as far as it will go.
~ Close the fuel filler flap. T
o avoid fuel spilling or evaporating from the
fuel tank always close fuel cap properly and
completely .
A WARNING
-Im proper refueling or handling of fuel can
cause fire, explosion and severe burns.
- Fuel is highly flammable and can cause
severe burns and other injuries.
- Failure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fully into the fuel filler neck could cause
fuel to spray out of filler neck or to over­
flow. Fuel spray and overflowing fuel can cause a fire .
- Never use a cellular telephone while re­
fueling. The electromagnet ic rad iat ion
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle whi le re­
fue ling.
If in exceptional circumstances
you must get back in your vehi cle while
refueling, make ce rtain that you close
the door and touch metal to discharge
static electricity before touching the fill­
er 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 refu­
eling or filling a portable fuel conta iner.
- For your safety, we strongly recommend
that you do not travel with a portable
fuel conta iner in your vehicle . The con­
tainer, full or empty may leak and could
cause a fire, especially in a crash.
- If, u nder exceptional cir cumstances, you
must transport a portable fuel conta iner,
p lease observe the following:
- Never fill a portable fuel container
whi le it is anywhere in or on the vehicle
(for example, in the luggage compart­
ment, or on the trunk). Static electrici­
ty can build up while filling and can ig­
nite fuel vapors causing a fire .
- Always place a portable fue l conta iner
on the ground before filling.
