The needles in the instrument cluster illu­
minate when the ignition is switched on.
The dials also illuminate when the light s
are switched on . The instrument illumina­
tion dims automatically as the amount of light outside decreases . This function re­
m inds the driver to turn the head lights on
at the app ropriate time.

T he date, t ime of day, time and date format
can be set in the MMI. Re fer to th e MMI own­
er's manual for instruct ions.
(D Tips
- When you switch off the ignition or open

Tachometer
The tachometer displays the engine speed in
revolutions per minute .
The beginning of the red zone in the tachome­
ter indicates the maximum permiss ible en­
g ine speed for all gears once the engine has
been broken in and when it is warmed up to
operat ing temperature. You shou ld select the
"D/S" (Drive) selecto r lever pos ition or take
your foot off the accelerator peda l before
reaching th is area .
It is best to avoid high engine speeds, even
when dr iv ing in tiptron ic mode ~
page 115 .
(D Note
The tachometer needle
(D ¢ page 10,
fig. 3
shou ld only be in the red zone brief­
ly: otherwise, this increases the risk of en­
gine damage.
@) For the sake of the environment
Upshift ing early helps you to save fuel and
reduce operating no ise.
Odometer
Fig. S In strument cl uster: odo meter an d reset butto n
The distance driven is shown in miles "mi" or
in kilometers "km" . The measurement units
(mi les "mi"
I kilometers "km") can be
changed in the MMI. For more info rmation,
refer to your M MI operating instructions.
Odometer /trip odom eter
@ -The odometer shows the total d ista nee
that the veh icle has been driven .
Instrument s an d indi cat or l amp s 11
@ -The trip odometer shows the distance
that the vehicle has been driven since the trip
odometer was last reset. It can be used to measure short distances. The last digit ind i­
cates 1/10 miles or 100 meter increments .
The trip odometer can be reset to zero by pressing the
I o.o I button ¢ page 10, fig. 3.
Malfunction indicator
If there is a malfunct io n in the ins trumen t
cl uster,
DEF will appear in the trip odometer
display. Have the malfunction corrected as
soon as possib le .
(D Tips
- Whe n you switch off the ignit ion or open
the driver's door, the odometer is dis­
played for approximately 30 seconds.
- Yo u can also turn on the display with the
j o.o j button when the ignition is switch­
ed off~
page 10, fig . 3.
Outside temperature display
The instrument cluster display shows the out­
s ide temperature. At temperatu res below
41 °F (+S °C), a snowf lake symbol appears in
front of the temperature display .
If your vehicle is stationary or if you are driv­
ing at very low speeds, the temperature d is­
played may be slightly higher than the actual
temperatu re outs ide due to the heat rad iating
from the engine.
,&. WARNING
N eve r assume that the roads a re free of ice
based on the outside temperature display.
Be awa re that there may be ice on roads
even when the outside temperature is
around 41 °F ( +S °C) and that ice can in­
crease the risk of accidents.
(D Tips
You can change t he measurement un its,
for example fo r temperature or speed, in
the MMI.

12 Instrum ent s and indicator lamp s
Fuel level
The display @
c;, page 10, fig. 3 only works
when the ignition is sw itched on . When the
d isplay has reached the reserve mark, the bot­
tom LED wi ll turn red and the
tD indicator
light turns on¢
page 23 . The bottom LED
blinks red when the fue l level is very low .
The on -board computer shows the range
based on the fuel leve l
c;, page 2 7, On-board
computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data ¢
page 280.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tem­
perat ure is h igh. This is not a cause for con­
cern as long as the. indicator light in the
display does not t urn on. Hot range
If the L
EDs in the upper area of the d isp lay
and the. indicator light in the instrumen t
cluster disp lay t urn on, the coo lant tempe ra­
ture is too high
c::> poge 19.
A WARNING
-Always observe the warning in
c;, page 214 before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment .
You could burn yourself. Let the engi ne
coo l off first until you can no longe r see
or hea r steam or coolant escaping.
([) Note
- Add itiona l headlights and other compo ­
ne nts in front of the a ir intake impairs
the cooling eff ect of the coolant. This in­
creases the risk of the engine over heat ­
ing dur ing high outs ide temper atures
and heavy eng ine load .
- The front spoiler also he lps to distr ibute
cooling air correct ly wh ile driving.
If the
spoiler is damaged, the coo ling effect
wi ll be impai red and the risk of the en­
gine overheating will increase. See an au­
thorized Audi dealer o r authorized Aud i
Service Facility for ass istance.

!?) Engine speed limitation
Appl ies to vehicles: with engine speed limitation
(Ill Max. engine spee d: XXXX rpm
The engine speed is automatically lim ited to
the speed disp layed in the driver information
system. This protects the engine from over­ heat ing.
The engine speed limitation deactivates once
the eng ine is no longer in the cr it ica l tempera ­
ture range and you have released the accelera­
tor peda l.
If the engine speed limitation was activated by an eng ine control malfunction, the~ indi­
cator light also turns on. Make s ure the en­
g ine speed does not go above the speed dis­
p layed, for examp le when downsh ifting. Drive
to an author ized Audi dealer or author ized
Aud i Service Fac ility immediately to have the
malfunct ion corrected .

System indicator light (MIL)
The system indicator ligh t (M IL) ¢.§ in the in ­
str ument cl uster is part of the On Board Diag­
nostic System (OBD II).
T he warni ng/i ndicator light t urns on when the
ignition is sw itched on and t urns off once the
engine is sta rted and is runn ing in id le at a
stab le speed. This indicates that the MIL is
funct ioning correct ly.
If the light does not turn off after sta rting
the engine

indicate there is a ma lfunction in the engine.
If the indicator turns on, the cata lytic convert­
er may be damaged .

time and/or fast acceleration) and have the
malfunction corrected. See an authorized Audi
