Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .

The follow ing information is cont in uo usly
eva luated by the trip computer and can be dis­
p layed sequentially in the instrument cluster
display:
F u el range
The estimated c ruising range in miles (km)
appears in the display. The disp lay changes in
increments of 6 miles (10 km) .
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display .
Current fuel mileage
The instantaneous fuel consumption in miles
pe r gallon (l/100 km) is shown in this d isp lay.
When the veh icle is stationary, the most re­
cent fuel consumpt ion is displayed .
Average speed
The average speed in mph (km/h) since the
last time the display was reset appears in the
d isplay.
Elapsed time
The length of time that you have been driving
since you last rese t the memory appears in
this display . The maximum time period that
can be recorded is 999 hou rs and 59 minutes .
Distance
T he elapsed dis tance s ince the last time the
memo ry was cleared appears in the d isp lay .
The maxim um distance that can be recorded
is 9,999 .9 miles (9,999.9 kilometers) .
a) Tips
-Fuel consumptions (average and cur ­
rent), range and speed are d isp layed in
metric units on Canadian mode ls.
- All stored values will be lost if the vehi ­
cle battery is d isconnected.
Memories
The trip computer is equipped with two fully
automatic memories as well as an efficiency
program.
Fig . 10 Tr ip compute r d isplay: me mory level 1
You can switch between the trip computer 1
and 2 and the effic iency program* by pressing
the
IRES ET I button @ Qpage 21, fig . 11 .
You can tell wh ich memory level is currently
active by the number o r the sig n in the display
¢ fig . 10 . The data from the s ingle-t rip mem­
ory (memory level 1) is being displayed if a
1
appea rs i n the display . If a 2 is shown, then
t h e dat a from the tota l-t rip memory is being
displayed (memory level 2). The f ue l pump
nozzle
ii indicates the efficiency program *

Single-trip memory (Trip computer 1 )
The sing le- trip memory stores the tr ip infor ­
mation from the time the ign it ion is tu rned on
u nt il it is turned off.
If t he trip is cont inued
with in 2 hour s from the time the ignition was
turned off, the new data will be included in ..,.

your fuel tank
Gasoline
Fuel supply
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recomm endation
The fuel recommended for your vehicle is un ­
lead ed pr emium
grade gasoline . See also
¢ page 239, Data . Audi recommends using
TOP TIER Detergent Gasol ine with a minimum
octane rating of 91 AK I (95 RON). For more
information on TOP TI ER Detergent Gasoline,
p lease go to the officia l website (www.toptier­
gas.com).
The recommended gasoline octane rating for
your engine can a lso be found on a label locat­
ed on the inside of the fuel filler flap . This rat­
ing may be specified as AKI or RON.
Your veh icle may also be operated using un­
leaded regular gasoline with a minimum oc­
tane rating of 87 AKI/91 RON . However, using
87 AKI/91 RON octane fue l wi ll slightly re ­
duce engine performance.
U se unl ead ed gasolin e onl y. Unleaded gaso­
line is available throughout the USA, Canada ,
and in most European countries . We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline may not be available.
F or more informat ion on refue ling your vehi­
cle, see
¢ page 175.
Octane rat ing
Octane rating ind icates a gasoline's ability to
resist engine damaging "knock" caused by
premature ign ition and detonation. Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane ratings that can us
ually be found on the fi ller
pump:
- Premium Grade: 91 -96 AKI
- 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 .
(D Note
-Do not use any fuel w ith octane rat ings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline! The use of
leaded gasoline w ill severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions .
Blended gasoline
Use of gaso line co ntainin g alc ohol or
MTBE (m ethyl tertia ry butyl eth er)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
fo llowing criteria:
Blend of gaso line m ethanol (wood alc ohol or
methyl alcohol )
-Anti -knoc k index must be 87 A KI or h igher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents .
Blend of g asoline and etha nol (gra in alcohol
or eth yl alcohol )
-Anti -knock index must be 87 AKI or higher .
- Blend must not contain more than 10% ethanol.
Blend of g asoline a nd MTBE
-Anti-knock index must be 87 AKI or h igher . ll-

1 76 Fuel supply and filling your fuel tank
transport fuel to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 - 86).
(D Note
Never drive your vehicle until the fuel tank
is completely dry. The irregular supply of
fuel can cause misfiring. Gasoline could
enter into the exhaust system and damage
the catalytic converter.
Refuelling
Fig. 132 Driver's door: Un locking fuel filler flap
Fig. 133 Fuel cap hooked on the opened fue l filler flap
When adding fue l, the ignition and any ce llu­
lar phones in the vehicle must be switched
off .
Taking the fuel cap off
• To open the fuel filler flap, pull the button
9fig. 132.
• Unscrew fuel filler cap counter-clockwise
and hang it on the fuel filter flap¢
fig. 133 .
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.
Putting the fuel cap back on
• After filling your tank, twist the fuel filter
cap clockwise until you hear a definite click.
• 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 fill­
er 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.
- Fue l 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 filter 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 electromagnetic radiation
can cause sparks that can ignite fuel va­
pors and cause a fire.
- Never get back into your vehicle while re­
fueling.
If in exceptional circumstances
you must get back in your vehicle while
refueling, make certain 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 container.
