The illum inat ion for the instrument cluster lights up whenever you
switch o n the ignition with the
vehicle headlight s off. As the daylight
fades, the instrument cluste r illum ination likewise d ims automati­
cally and w ill go out completely when the outside light is very low .
T his featu re is mean t to remind you to switch on the headligh ts when
outs ide light conditions become poor .•
Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the need le remains at the le ft end of the gauge, the engine
st ill has not re ached its operating tem perature. Avoid high eng ine
speeds, heavy engine loads and heavy throttle applicat ions.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
go furthe r to the right. This is no need to wo rry as long as the _JL
wa rning light in t he instrument cluster does not illuminate .
Warning light in the instrument cluster -t
When the _ L warning light starts to flash, this ca n mean one of two
t hings: e ither the cool ant
temperature is too h igh, or the coolant
level is too low=> page 29. _,.

(I] Tips
• The dig ital clock and the odometer are turned on for about 30
seconds when the driver's door is opened.
• When the ign ition is turned off, the odometer read ing and the
digital clock with date display can be switched on for about
30 seconds by press ing the
I CH ECK I button::::> page 13, fig. 5. •
Speedometer with odometer
The speedometer shows you the vehicle speed, and the
odometer shows you how many miles (kilometers) you
have driven.
Fig. 4 Instrume nt
cluster Odometer and res et button
The odometer and trip odometer are located inside the speedometer .
• USA models -Miles
• Canada models -Kilometers
You can switch the display from miles to kilometers and vice versa via
the MMI.
Lower odometer
The lower odometer shows the total number of mi les (kilometers)
driven.
Upper odometer (trip odometer)
The upper odometer shows the total number of miles (ki lometers)
dr iven since you last reset the odometer to zero . You can use th is
odometer when you want to keep track of how many m iles (kilome­
ters) you have dr iven for a single trip or errand. The last digit indicates
1/10 of a mile (100 meters) .
You can reset the trip odometer to zero by pressing the Reset button
[0.0].

will appear in the trip odometer and will stay on. Contact your autho­
rized Audi dealer to have the problem corrected.
Immobilizer
When you switch on the ign ition, the data chip inside the key is "read"
by the immobilizer system.
If an unauthori zed key is inserted into the ignition lock, the word
SAFE will come on and stay on . You will not be able to start the

Speed warning system
Overview
The speed warning system helps you to keep your driving
speed below a set speed limit.
T he speed warning system warns the driver if he exceeds a previously
s tored maximum spee d. A w arning tone will sound as soon as the
vehicle speed exceeds the set speed by about 3 mph (3 km/h) . A t the
same time, a warning symbol appears in t he disp lay .
Th e spee d wa rn ing system has
two warning threshold s that function
independently of each other and that have somewhat di fferent
purp oses:
Speed warning 1 8 (USA models) /8 (Canada
models)
You can use speed warn ing 1 to set the max imum speed w hile you are
driv ing. This setting will remain in effect until yo u turn off the igni­
tion, assum ing that yo u have not changed or reset the setting .
Th e spee d warn ing symbo l
B (USA models)/ 0 (C anad a mode ls) in
t he warning 1 display appears when you exceed the maxim um speed .
It goes out when the speed falls be low the stored maximum speed .
Th e spee d warn ing sy mbo l w ill also go o ut if t he speed
exceeds the
sto red maxim um speed by more than about 25 mph
(40 km/ h) for at
least
10 sec onds . H oweve r, th is doe s not rese t the stored maxim um
speed.
Setting spee d warning 1
=> page 35.
Speed warning 2 0 (USA models) /0 , (Canada
models)
Storing warn ing 2 is recommended if you always want to be reminded
o f a ce rtain speed, fo r example when yo u are traveling in a co untr y
that has a genera l maximum speed lim it, or if you do not want to
exceed a specified speed for winter tires.

Warm and cold
Climate controls
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 75
°F (+23 °C).
- Press the
[AUTO] button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting , as desired , to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode ~ page 106
for year-round comfort .
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
If the outside temperature is
low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle.
The air pollutants filter must be changed at the intervals specified in
your Warranty
& Maintenance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution , the filter
may need to be changed more frequently than specified in your Audi
Warranty
& Maintenance booklet. If in doubt, ask your authorized
Audi Service Advisor for advice.
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings and
does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored.

& WARNING (continued)
• Please note that inadvertently "resting" your foot on the accel­
erator pedal causes the cruise control not to brake. This is because
the cruise control is overridden by the driver's acceleration.
[ i] Tips
The brake lights illuminate as soon as the brakes decelerate automatically. •
Changing speed
-Press lever in the
0 or O direction=> page 126, fig. 136
to increase or decrease your speed.
- Release the lever to save that speed.
Change speed in increments of 1 mph (1 km/h) by lightly pressing the
lever. If you keep the lever pressed down, you will alter your speed in
S mph (10 km/h) increments.
You can also press the accelerator pedal down to increase your speed,
e.g. if you want to pass someone. The speed you saved earlier will
resume as soon as you release the accelerator pedal.
If, however, you exceed your saved speed by S mph (10 km/h) for
longer than S minutes, the cruise control will turn off temporarily .
The green symbol in the display~
page 126, fig. 13 7 is replaced with
a white symbol. The saved speed remains the same.•

& WARNING
Following other vehicles too closely increase s the risk of a crash

• Following other vehicles too closely, particularly at higher
speeds inc reases the r isk of collisions and serious personal injury.
• Setting short distances to the traffic ahead redu ce s the time

make s it even more ne ce ss ary to pay clo se attention to traffi c.
• Always select a speed and distance to traffic ahead that is safe
and appropriate under the prevailing traffi c, road, weather and

• Never allow the closing speed between you and other vehicles
to be so high that the Adaptive Cruise Contr ol may not be able to
