(D Note
Never drive until the tank is completely emp­
ty. The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter .
Indicator lights
Description
The indicator lights in the instrument cluster
blink or turn on. They indicate functions or mal­
functions.
With some indicator lights, messages may ap­pear and warning signals may sound. The indica­
tor lights and messages in the display can be cov­
ered by other displays. To show them again, se­ lect the tab for the indicator lights and messages
using the multifunction steering wheel
c;, page 19. If there are several malfunct ions,
you can display them one at a time using the
thumbwheel.
Some ind icator lights in the display can display in
several colors .
Overview
Some indicator lights turn on briefly as a function
check whe n you switch the ign ition on . These sys­
tems are marked with a
,I in the following tables.
If one of these indicator lights does not turn on,
there is a ma lfunction in that system.

Ill co
-Do not inadvertently press the accelerator
pedal when the vehicle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, even if the parking brake
is set . This could result in a crash .
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
- Never leave your vehicle with the engine running while in gear.
If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position .
- To decrease the risk of an accident, these­
lector lever must be in the P position and
the parking brake must be set before open­
ing the hood and working on a running en­
gine. Always read and follow the applicable
warnings¢
page 244, Working in the en­
gine compartment.
{[) Note
Never let the vehicle roll downhill with engine
off and the selector lever in the
N position,
because this could damage the automatic
transmission and catalytic converter.
@ Tips
- Drive select: sporty shifting characteristics
can be selected using the
Dynamic driving
mode. The Infotainment display shows 5 as
the selector lever position instead of D.
- If you accidentally select N while driving,
take your foot off the accelerator pedal im­
mediately and wait for the engine to slow
down to idle before selecting Dor 5 .
- If there is a power failure, the selector lever
will not move out of the P position. The
emergency release can be used if this hap­
pens. Left-hand drive vehicles

Driving
Selector lever lock
The selector lever lock prevents you from select­
ing a gear accidentally, causing the vehicle to
roll.
Fig. 64 Selecto r lever lock
To release the selector lever lock:
.,. Switch on the ignition.
.,. Press the brake pedal
while pressing the inter-
lock button.
Automatic shift lock (ASL)
The selector lever is locked in the P and N posi­
tions when the ignition is switched on. You must press the brake pedal to select another position.
You must also press the interlock button if you
are moving from the
P position. The following
message appears in the display when the selector
lever is in the P or
N position to remind the driv­
er:
To select a gear, please press brake pedal and press lock button on selector lever
The automatic shift lock only functions when the
vehicle is stationary or at speeds below 1 mph
(2 km/h). At higher speeds, the lock is automati­
cally deactivated in the N position.
The selector lever is not locked when shifting
quickly through N, for example from R to D. This
makes it possible to free the vehicle when it is
stuck by "rocking" it. The selector lever lock en­
gages if the lever stays in the N position longer
than approximately 2 seconds when the brake
pedal is not pressed.

Check ing and F illing
Checking and Filling
Fuel
Gasoline grade
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gasoline can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AKI or in RON.
The fo llow ing headings match the correspond ing
sticker in the fue l filler door.
UNLEADED FUEL ONLY MIN. (R+M) /2 87
Regula r/ MIN. RON
91 Regular
Use regu la r gaso line with minim um 87 AKI/
91
RON ~ 0 .
The max imum eng ine powe r is only reached if
p rem ium gaso line 91 A KI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M)/2
91 / SUPER MIN. RON 95
Using premium gasoline with m inim um 91 AKI/
95 RON is recommende d.
If premium gasoline is not available, you can also
use reg ula r gaso line 87 A KI/ 91 RON . Howeve r
this does reduce t he e ngine powe r slight ly.
(D Note
- Fill ing the tank just one time with leaded
fuel or other meta llic additives will cause
permanent de te riorat io n to the catalyt ic
conve rter func tion.
- Whe n gasol ine with an oc tane r ati ng that is
too low is used, high speeds o r heavy engi ne
l o ad can lead to engi ne d amage.

(D Tips
The vehicle may be filled with fuel that has a
h igher octane rating than what is requi red by
the eng ine.
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol o r MT BE (commonly referred to as oxygen­
ates) if the blended m ix tu re meets t he fo llow ing
c rit er ia:
Blend of gasoline m ethano l (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 tha n 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- Anti-k noc k index mus t be 87 AK I or higher.
- Blend must not conta in mo re than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or higher.
- Blend mus t contain no t mo re than 15% MT BE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for w inter or s umme r dr iv ing . Dur­
i ng seasonal change-ove r, we s ugges t that yo u
fill up a t busy gas stat ions w here the seasona l
adjus tment is mo re li kely to be made in t ime .
(D Note
-Metha nol fuels which do not meet these re­
quirements may cause cor rosion and dam ­
age to plas tic and rubber com ponen ts i n t he
fue l system.
- Do not use f ue ls that fa il to meet the speci ­
fie d cr iteri a in th is chap ter.
