the following notes about the temperature rang­
es.
Cold ran ge
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high eng ine speeds, full ac­
celerating and heavy eng ine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on.
If the . indicator light in the instru­
ment cluster d isplay turns on, the coolant tem­
perature is too
high ¢ page 13.
@ Note
-Aux iliary headlights and other accessories in
front of the coo ling-air intake impa ir the
cooling effect of the coolant . This increases
the risk of the engine overheating dur ing
high ou tside temperatures and heavy en­
gine load.

-The front spoiler also he lps to distribute
cooling air while driving . If the spoiler is
damaged, the cooling effect w ill be im­
paired and the r isk of the engine overheat­
i ng will increase. See an author ized Audi
dealer or authorized Audi Service Fac ility for
ass istance.
Tachometer
The tachometer displays the engine speed in rev­
olutions per minute (RPM) .
You should shift to the next lowest gear when
the speed is below 1,S00 RPM. The beginn ing of
the red zone in the tachometer indicates the maximum permissible engine speed for all gears
once the engine has been broken in and when it is
warmed up to operating temperature. Before
reaching the red zone, yo u should shift into the
next higher gear, choose the Dor S se lector lever
position, or remove your foot from the accelera ­
tor peda l.
@ Note
The needle in the tachometer @ ¢ 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.
@ For the sake of the environment
Upshifting early he lps you to save fuel and re ­
duces operating noise.
(D Tips
Applies to: S models
The engine speed is limited when the eng ine
is cold - the full engine output is not availa­
ble. When the engine is at operating temper­
ature, the red area in the tachometer moves
to a hig her RPM range .
Fuel level
The display @ only wo rks when the ignition is
sw itched on. If the fuel level d rops below 2 .6 gal
(10 li ters), a red L ED w ill tur n on and t he

! ?) Engine speed limitation
Applies to: ve hicles with eng ine speed lim itat ion
Ill Maximum engine speed: XXXX rpm
The engine speed is automatically limited to the
speed displayed in the instrument cluster. This
protects the engine from overheating.
The engine speed limitation deactivates once the
engine is no longer in the critical temperature range and you have released the accelerator ped­
a l once.
If the engine speed limitation was activated by
an engine contro l ma lfunction, the
ll:a indicator
light also turns on. Make sure that the speed
does not go above the speed displayed. Drive to
an author ized Audi dealer or authorized Audi
Service Facility immediately to have the malfunc­
tion corrected .

Fig . 64 Attachment poi nts for the roof rack
If luggage or cargo is to be carried on the roof,
you must observe the following:
-Only a specia lly designed roof ra ck may be used
o n your veh icle. These roof racks are the basis
for a complete roof rack system. Additional at ­
tachments/carrier systems are necessary to
transport luggage and sports equipment. We
recommend roof racks and attachments from
the Audi Genu ine Accessor ies program.
-When installing the roof rack, make sure that it
is mounted only at the designated points on
the roof
i:> fig. 64 .
-Note the perm itted axle load, permitted total
weight, and permitted roof load of your vehicle
<=> page 246. The roof load is the tota l of the
weight of t he roof rack, the attachments and
the cargo you are carrying. However, you must
also note the permitted load of the carrier sys­
tem being used .

A WARNING
,-
-Follow the installation instructions provided
w it h the roof rack system. If you do not se­
cure the roof rack system and objects on the
roof correctly, they could come loose from
the vehicle and ca use an accident .
-Using a roof rack system increases the r isk
of an accident, because it changes the ve hi­
cle handling characte rist ics wh ile driving by
shifting the center of grav ity and/or the in­
creasing the sur face area exposed to wind .
You may need to adapt your driving sty le
and speed to the current conditions.
CD Note
Make sure that the luggage compartment lid
and the sunroof* do not come into contact
with objects on the roof when they are open .
@ For the sake of the environment
Your vehi cle will require mo re fuel d ue to the
increased wind resistance. So remove the roof
rack after using it.

Warm and cold
Climate control system
Description
The climate control system warms, cools and re­ moves humidity from the air in the vehicle interi­
or. It is the most effective when the windows and
sunroof* are closed. If there is a bui ld-up of heat
inside the vehicle, ventilation can he lp to speed
up the cooling process.
I n all heating mode functions, except for defrost,
the blower only switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature.
Pollutant filt er
The po llutant filter removes poll utants such as
dust and pollen from the a ir .
Ke y re cognition

The blower sett ing and air distribution are stored
automatically and ass igned to the remote control
key that you are using.
A pp lies to: ve hicles w ith 4 -zo ne del uxe automatic c limate
co ntrol
The climate control set tings are automatically
stored and assigned to the remote control key
that is in use.
A WARNING
Poor visibility can lead to accidents.
- For safer driving, keep all windows free of
ice, snow and fog .
- Become familiar as quickly as possible with
the correct use and function of the climate contro l system, especially with the defrost­
ing and defogg ing function.
58
- When the temperature is below freezing,
only use the windshield washer system after
the windshield has been warmed by the cli­ mate control system . The washer fluid could
freeze on the w indsh ield and impair v isib il i­
ty .
@ 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 dea ler or authorized
Audi Serv ice Facility.
- Repa irs to t he Aud i climate control system
require special techn ical know ledge and
special tools. See an aut ho rized Aud i dea le r
or authorized Aud i Serv ice Fac ility .
@) For the sake of the environment
To save fue l, turn off cooling mode by press­
i ng the
IA/Cl button. This will a lso reduce
emissions.
(D Tips
- T o prevent i nterference with t he heat ing
and cooli ng outpu t and to p revent the win­
dows from fogging over, the a ir intake in
front of the windshie ld must be free of ice,
snow or leaves.
- C ondensation from the coo ling system can
drip and form a pudd le o f water under the
vehicle . This is norma l and does not mean
there is a leak.
- Th e energy management system may tem ­
porarily switc h
off certain functions, such as
the seat heating* or rear window defogger.
These systems are ava ilable again as soon
as the energy supply has been restored.
