Cockpit overv iew
CD Note
-Auxiliary headlights and other accessories in
front of the cooling-a ir intake impair the
cooling effect of the coolant. This increases
the r isk of the engine overheat ing during
high outside temperatures and heavy en-
gine load.
- The front spoiler also he lps to distr ibute
cooling air correctly wh ile driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over­
hea ting will inc re ase. See an a uthorized
A udi dealer or au thori zed A udi Service Fa­
cility for assistance .
Tachometer
The tachometer display s the engine speed in rev­
olutions per minute
(RPM).
You shou ld shift to the nex t lowest gea r whe n
the speed is below 1,500 R PM. The beginn ing of
the red zone in the t achometer indic ates the
maxim um permissible eng ine speed fo r all gears
once the engine has been broken in an d when it is
warmed up to operating temperature . Before
reaching this zone, you should shift into the next
h ighest gear, select the D selector lever pos ition,
or remove your foot from the accelerator pedal.
CD Note
The needle in the tachometer @ <=:> page 9,
fig. 3 may only be in the red area of the gauge
for a short t ime or the re is a risk of engine
damage. The locat ion where the red zone be­
gi ns varies depending on the engine.
@ For the sake of the environment
Upshifting early helps you to save fuel a nd re­
duce operating noise.
Fuel level
The display ® only works when the ignition is
sw itched on. If the fuel level d rops below 4 gal
(15
L), a red L ED will light up and the ll) ind ica­
tor light will tur n on
<=:> page 24 . The red LED
will blink when the fuel level is very low.
10
The fuel tank capacity of your ve hicl e is listed in
the
Techn ical Data section <=:> page 334 .
CD Note
Never dr ive until t he ta nk is comp letely emp­
ty. The irreg ular su pp ly of fuel t hat res ults
from that can cause engine m isfires . Uncom­
b uste d fue l w ill then enter the exhaust sys ­
tem. This ca n cause overheating and damage
to the catalyt ic converter.
Odometer
Fi g. 4 Instru ment cluster: odometer a nd reset button
Upper odomet er
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances.
The trip odometer can be reset to zero by press ­
ing the ~ reset button.
Lower odometer
The lower odomete r shows the tota l distance
that the vehicle has d riven.
Malfunction indicator
If there is a malfunction in the instr ument clus­
te r,
DEF will appear in the trip odometer display.
Have the malfu nction corrected as soon as possi­
ble.

Driver information
system
On-board computer
F ig . 8 Instrument cluster: fuel co nsumption display

You can call up the fo llowing information in the
on-board computer:
- Da te
- Dr iv ing time from the short-te rm memory
-Average consumption from the short -term
memory
- Average speed from the short-term memory
- Distance driven from the short-term memory
- Current fuel consumption
- Short-term memory overv iew
- Long-te rm memory overview
The short-term memory collects driv ing inf orma­
tion from the time the ign ition is switched on un­
til it is switched off. If you continue driving with­
i n two hours after switch ing the ignit ion off, the
new values are included when ca lculating the cur­
rent trip information.
Unlike the short-term memory, the long-term
memory is not erased automatically. You can se­
lect the time period for evaluating trip informa ­
tion yourself .
Fuel consumption
The current fu el consumption can be shown us­
in g a bar graph ¢
fig. 8. The average consump­
tion stored in the short-term memory is also dis­
played . If the bar is green, your vehicle is saving
fuel through one of the fo llowing functions :
-Recuperation : electrical energy can be stored in
the vehicle battery when the vehicle is coast ing
or dr iving down hill. The bar will move towa rd
0 .
-Cylinder on demand system*: the engine auto­
matically switches four cylinders (4 .0L TFSI) or
six cylinders (6.3L FSI) off when lower power
output is required and other conditions are
met. This change is not noticeable to the pas­
sengers . The cylinders w ill switch on again
when higher power output is needed .

To preven t scratches on the g lass cove ring the
head -up d isplay, do not place any objects in
the projection opening .
(D Tips
-Sunglasses w ith polar izat ion fi lte rs and u n­
favorab le lighting conditions can have a
negative effect on the display.
- An optim um display depends on the seat
position and the height adjustment of the
head -up display.
- A specia l windshield is needed for the head ­
