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.

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

Refrigerator
Introduction
Applies to: vehicles with refrigerator
Clean the refrigerator before the first use ~ table
on page 308.
You can only switch the refrigerator on, if :
- the temperature in the luggage compartment
is less than 131
° F (55 °(). If the refrigerator is
switched on , it will automatically switch off if
the temperature in the luggage compartment
exceeds 131
° F (55 °(). If the temperature
goes back below 131
° F (55 °(), the refrigera­
tor will automatically switch on again.
- The charge level of the vehicle battery is suffi.
cient. The refrigerator is automatically switch­
ed off if the electrical system voltage falls be­
low the spec ified minimum value. This prevents
the vehicle battery from discharging . The re­
frigerator automatically switches back on if th e
electrical system voltage increases again, for
example after starting the vehicle.
When the cooling function is working optimally,
the cooling function reaches 43° F
(+6 °C) and
the free zing function reaches 21 ° F
(-6 °C). The
cooling temperature in the refrigerator also de­
pends on the luggage compartment tempera­
ture. When the temperature in the luggage com­
partment is high, there may only be a limited
cooling effect.
.&, WARNING
-
To avoid any injury risks to the passengers
caused by the refrigerator, the following safe­
ty precautions must be followed:
Seats and storage
-The maximum load capacity for the freezer
is
5.5 lbs (2 .5 kg).
- Never overload the refrigerator. There is a
risk of injury in the event of a collision or
sudden braking.
- The refrigerator cover must always be
closed and locked while driving. The refrig­
erator contents could enter the vehicle inte­
rior during a collision or sudden braking ma­
neuver, which increases the risk of injury.
- Never store flammable fluids, gas contain­
ers and similar objects in the refrigerator
due to the risk of an explosion . This also ap­
plies to goods and products that can emit
volatile or flammable gases.
-At temperatures of 32° F
(0 °() and lower,
frozen liquid inside glass containers can
cause the containers to burst.
(D Note
- The ventilation openings for the refrigerator
are at the rear panel trim panel in the lug­
gage compartment and must not be cov­
ered.
- If the refrigerator is not functioning correct­
ly, turn it off to prevent any damage. Have it
checked by an authorized Audi dealer or au­
thorized Audi Service Facility.

0 co .... N ,..... N .... 0 0 :c ' Warm and cold Deluxe automatic
climate control
Description
The climate con trol system warms, coo ls and re ­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed. If there is a bu ild-up of heat
i n side the veh icle, ven tilat ion can he lp to speed
up the cooling process .
In a ll heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filt er
The po llutant filter removes pollutants such as
d ust and pollen from the air.
Key recognition
The clima te control settings are automatically
s tored and assig ned to th e remo te contro l key
that is in use.
& WARNING
Poo r visibility can lead to accidents.
- For safer d riving, keep all windows free of
ice, snow and fo g.
- B ecome familia r as quickly as possible wi th
the correct use and function of the cl imate
contro l system, especially with the defrost­
ing and defogging function.
- When the temperat ure is below freezing,
only use the windsh ield washer system after
Warm and cold
the windshield has been warmed by the cli­
mate control system. The washer fluid could
freeze on the windshie ld and impair visib ili­
ty .
(D Note
-If you suspect that the climate contro l sys­
tem is damaged, switch the system off to
prevent further damage and have it checked
by an authorized Aud i dealer o r authorized
Aud i Serv ice Facility.
- Repa irs to the Aud i climate control system
require special technical know ledge and
special tools . See an autho rized Aud i dea le r
or authorized Audi Service Fac ility.
@ For the sake of the environment
Reducing the amount of fuel used also re ­
duces the amount of pollu tan ts that enter the
ai r.
@ Tips
- To prevent interference with the heat ing
and coo lin g output and to prevent the wi n­
dows from fogging over , the air intake in
fro nt of the windshie ld m ust be free of i ce,
