2013 AUDI TT fuel pump

Trip computer
Introduction
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 8 T rip comp ute r 1
The fo llow ing informa tion is cont inuo usly
eva luated by the trip compu ter and can be dis ­
p layed sequentia lly in the instrument cl uster
d isplay:
Fuel range
The estimated c ruising ra nge in miles (km)
appears in the d isplay . The disp lay changes in
increments of 6 miles (10 km) .
Average fuel mileage
The average fue l economy in MPG (l/ 100 km)
since you last clea red the memory appears in
t his 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 ve hicle is stationary, the most re­
cent fuel consumpt io n is displayed.
Average speed
The average speed in mph (km/h) since the
last time the display was reset appears i n the
d isp lay.
Elap sed t ime
The length of time that you have been driving
since you las t reset the memory appears in
this display . The maximum t ime period that
can be recorded is 999 ho urs and 59 minutes .
Driver in formation system 23
Distance
The elapsed dis tance sin ce the las t time the
memory was cleared appears in the d isp lay .
T he maxim um distance that can be recorded
is 9 ,999.9 miles (9,999 .9 k ilometers) .
(D Tips
- Fuel consump tions (average and cur ­
rent), range and speed are disp layed in
metric un its on Canadian mode ls.
- All sto red val ues wil l be lost if t he vehi ­
cle battery is d isconnected .
' . Memories
The trip computer is equipped with two fully
automatic memories as well as on efficiency
progrom.
Fi g. 9 Trip co mputer d isplay: memo ry level 1
You can switch between the trip computer 1
and 2 and the efficiency program* by pressing
the
I R ES ET I button @ c::> page 24, fig . 10 .
You can tell wh ich memory leve l is currently
active by the number or the sign in the display
c::> fig . 9. The data from the single-trip memo­
ry (memo ry level 1) is being displayed if a
1
appea rs i n t he display . If a 2 is shown, then
the data from the total- trip memory is being
displayed (memory level 2). The f ue l pump
nozzle
ii indicates the efficiency program *
c::> page 26.
Single-trip memory (Trip computer 1 )
The sing le -t rip memory stores the tr ip info r­
ma tion from the time the ig nition is tu rned on
u nt il it is tur ned off. If the tr ip is cont inued
within 2 hour s from the time the ignit ion was
turned off, the new data will be included in ..,.

Gasoline
Fuel supply
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is un­
lead ed premium
grade gasoline . See also
¢
page 240, Data . Audi recommends using
TOP TIER Detergent Gasoline 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 also 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
l eaded regular gasoline with a minimum oc­
tane rating of 87 AKI/91 RON. However, using
87 AKI/91 RON octane fuel wi ll slightly re ­
duce engine performance.
Use unleaded gasoline only. 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 information on refueling your vehi­
cle, see¢
page 177.
Octane rating
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 r
atings that can usually 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 ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage will 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 gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti -knoc k index must be 87 A KI or higher.
- Blend must contain no more than 3% meth-
anol.
- 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 contain more than 10%
ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher. ll-

transport fue l to use for your lawn mower,
snow blower, etc., be very careful and al­
ways observe local and state laws regard­
ing the use, transportat ion and storage of
such fuel containers . Make certain the con­
tainer meets industry standards (A NSI/
AS TM F852 -86) .
(D Note
Never drive your vehicle unti l the fuel tank
is completely d ry. The irreg ular s upply of
fuel can cause misfir ing. Gasoline cou ld
e nte r into the exhaust system and damage
t he cata lytic conve rter.
Refuelling
Fi g. 12 9 Drive r's doo r: Un lo cki ng fuel f ille r flap
Fi g. 130 Fu el cap hooke d on the opened fuel filler flap
When adding fue l, the ignition and any ce llu­
lar phones in the vehicle must be sw itched
off .
Tak ing the fuel cap off
• To open the fuel filler flap, pull the button
r:> fig. 129.
• Unscrew fuel filler cap counter-clockwise
and hang it o n the fuel filler flap ¢
fig. 130 .
Refuelling procedure
• Insert the f uel no zz le from the gasoline
pump into the fuel fi ller neck as far as it w ill
go .
• Select a med ium refuelling rate so that the
no zz le sw itches off automatically when the
tank i s full.
Putting the fuel cap back on
• After fi lling your tank, twist the fuel filler
cap clockw ise until you hear a definite click.
• Close the fue l filler flap.
T o avoid fuel s pill ing or evaporating from the
fuel tank always close fuel filler cap properly and completely . An improperly closed fuel fi ll­
er cap may also cause the MIL lamp¢
page 30
to come on.
A WARNING
Imp roper refue ling or handling of fuel can
cause fire, explosion and severe burns.
- Fue l is highly flammable and can cause
severe burns and other injur ies .
- Fai lure to shut the engine off while refu­
eling and/or to insert the pump nozzle
fu lly into the fuel filter neck could cause
fuel to spray out of filler neck or to ove r­
f low. Fuel spray and overflowing fuel can
cause a fire.
- Never use a ce llu lar telephone whil e re­
fue ling . Th e e lec tromagnet ic radiat io n
can cause spa rks th at can igni te fuel v a­
pors an d cause a fire.
- N ever get back in to your vehicle whi le re­
fue ling.
If in excep tio nal cir cumstances
you must get back in your vehi cle while
ref ueling, make ce rtain that you close
the door and touch metal to discharge
static electricity be fore touching the fill­
er nozzle again . Static e lectr icity can
cause sparks that can ignite fuel vapors
re leased d uring refueling .
- Never smoke or have an open f lame any­
where in or near your ve hicle when refu­
eling or fi lling a portable fue l conta iner .
