t h e following notes about the temperatu re rang­

Cold range
If only the LEDs at the bottom of the gauge turn

perature yet. Avoid high eng ine speeds, f ull ac­
c e le ra ting and heavy e ng ine loads.

CD Note
- Auxiliary headlights and other accessories in
front of the cooling-air 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 helps 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
heating will inc rease. See an a uthorized
A ud i dealer or authorized Audi Service Fa­
cility for assistance .
Tachometer
The tachometer displays the engine speed in rev ­
olutions per minute
(RPM).
You should shift to the next lowest gea r when
the speed is below 1,500 RP M. The beginn ing of
the red zone in the tachometer ind icates the
maximum permissible engine speed fo r all gears
once the engine has been broken in and when it is
warmed up to operating temperature . Before
reaching this zone, you should shift into the next
highest gear, select the D selector lever position,
or remove your foot from the accelerator pedal.
~ Note
The needle in the tachometer @ c:> page 9,
fig. 3 may only be in the red area of the gauge
for a short time or there 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 and re­
duces operating noise.
Fuel level
The display @ only works when the ignition is
sw itched on. If the fuel level drops below 4 gal
(15
L), a red L ED will light up and the Ill indica­
tor light will turn on
c:> page 24. The red LED
will blink when the fuel level is very low.

The fuel tank capacity of your ve hicle is listed in
the
Techn ical Data section c:> page 334.
CD Note
Neve r drive until the tank is comp letely emp­
ty. The irregu lar supply of fuel th at results
from that can cause engine misfires . Uncom­
busted fuel w ill then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalyt ic converter.
Odometer
Fig. 4 Instru ment cluster: odometer and reset button
Upper odometer
The trip odometer shows the distance driven
s ince 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 total distance
that the vehicle has driven.
Malfunction indicator
If there is a malfunction in the instrument clus­
ter,
DEF will appear in the trip odometer display.
Have the malfunction corrected as soon as possi­
ble.

F ig . 8 Instrument cluster: fuel consumpt ion d isplay

You can call up the fo llowing info rmat ion in the
on-board computer:
- Da te
- Dr iv ing t ime 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 overv iew
The short-term memory collects drivi ng informa­
tion from the time the ignition is switched on un­
ti l 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.
Un like the sho rt -term memory, the long-term
memory is not erased automatically. You can se­
l ect the time period for evaluating trip informa ­
tion yourself .
Fuel consumption
The current f uel consumption can be shown us­
i ng a bar graph ¢
fig. 8. The average consump­
tion stored in the short-term memory is also d is­
played. If the bar is green, your vehicle is sav ing
fuel through one of the following functions :
-Rec uperation : electrical energy can be stored in
the vehicle battery when the vehicle is coast ing
or driving down hill. T he bar will move toward
0.
-Cy linder 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. Th is change is not noticeable to the pas­
sengers . The cylinders w ill switch on aga in
when higher power output is needed .
