The instrument illumination (for dials and
needles) turns on when the ignition is on
and the vehicle lights are turned off. As
the daylight fades, the illumination of the
dials likewise dims automatically and wil l
go out completely when the outside light
is very low. This feature is meant to rem ind
you to switch on the headlights when out­
side light conditions become poor.
Engine coolant temperature gauge
The engine coolant gauge CD¢ page 11, fig. 3
only works when the ignition is on. To prevent
damage to your eng ine, please note the fol­
l owing important points:
Engine cold
If only the LEDs at the bottom of the gauge
turn on, the eng ine has not reached operating
temperature yet . Avoid high engine speeds,
heavy engine loads and heavy throttle applica­
tions.
Normal temperature
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving cond i­
t ions. The LEDs higher up may turn on when
the engine is under heavy load or the exterior
temperature is high. This is no need to worry
as long as the. warning light in the instru­
ment cluster does not illuminate . If the LEDs
in the upper area of the display and the indica­
tor light . in the instrument cluster display
turn on, the coolant temperature is too high
¢page 16.
A WARNING
-Always observe the warn ing in
¢ page 222, before opening the hood
and checking the engine coolant level.

12 Instrum ent s and w arn ing /indic ato r light s
-Never open the engine hood if you see or
hear steam, or if you see engine coolant
dripping from the engine compartment.
You could burn yourself . Let the engine
cool off first until you can no longer see
o r hear steam or coo lant escaping.
@ Note
- Mounting additional lights or accessories
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator . At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo iler has been designed to
proper ly distribute the cooling air when
t h e ve hicle is moving.
If the spoiler is
dam aged, th is co uld red uce the cooling
effect and the engine co uld then over­
heat . Ask your authorized Audi dea ler for
assistance .
Tachometer (engine rev counter)
The tachometer indicates the engine RPM
(revolutions per minutes).
If engine RP M drops be low 1,500, yo u should
downshift to the next lower gear. The red a rea
at the end of the sca le indicates maximum
perm iss ib le engine RPM after the break-in pe­
riod. Before reaching this area, move these­
lector lever to position D/S (Drive) or ease
your foot off the accelerator pedal.
(D Note
The tachometer needle should on ly br iefly
be in the red zone: you could damage your
engine! The beginn ing of the red zone var­
ies depending on the engine .
@ For the sake of the environment
Upshifting early saves fuel and reduces en­
gine noise.
Fuel gauge
The fuel gauge only works when the ignition is
on .
If the fuel level d rops below 2 . 6 ga llons (10 liters), the bottom LED turns red and the
indicator light
ll'J turns on r=> page 22. The
bottom LED blinks red when the fuel level is
very low.
T he possible range based on the current fuel
level is shown in tab@r=>
page 24, fig . 4 .
(D Note
Never run the tank completely dry. An ir ­
r egular supply of f uel can cause engine
misfiring and fuel could enter the ex ha ust
system . The catalytic converter could then
overheat and be damaged.

& WARNING
- Automatic headlights are only intended
to assist the driver . They do not relieve
the driver of his responsibility to check
the headlights and to turn them on man­
ually according to the current light and
visibility conditions. For example, fog
cannot be detected by the light sensors.
So always switch on the headlights
io
under these weather conditions and
when driving in the dark.
- Crashes can happen when you cannot see
the road ahead and when you cannot be
seen by other motorists. Always turn on
theheadlightssothatyoucanseeahead and so that others can see your car from
the back .
- The rear fog lights should only be turned
on in accordance with traffic regulation,
as the lights are bright for following traf­
fic.
- Please observe legal regulations when using the lighting systems described .
@ Tips
-The light sensor* for automatic head­
light range control* is located in the rear
view mirror mount . You should therefore
not apply any st ickers to the windshield
in this area in order to prevent malfunc­
tions or failures.
- In the event of a light sensor malfunc­
tion, the driver is notified in the instru­
ment cluster display

Audi adaptive cruise control and braking guard 89
When approaching a moving vehicl e up ahead,
the adaptive cruise contro l system automati­
cally brakes to match that object's speed and
then maintains the stored distance.
If the ve­
hicle ahead accelerates, adaptive cruise con­
trol will also accelerate up to the stored
speed .
The higher the speed, the greater the distance
in yards (meters) ¢.&. . The
Distance 3 setting
is recommended .
The distances prov ided are specified values .
Depending on the driving situation and the
how the vehicle ahead is driving, the actual
distance may be more or less than these tar ­
get distances.
The various symbols for the time increments appear briefly in the information line @

A WARNING
Following other vehicles too closely in­
creases the risk of collisions and serious
personal injur y.
- Setting short distances to the traffic
ahead reduces the time and distance
available to bring your vehicle to a safe
stop and makes it even more necessary
to pay close attention to traffic. -
Always obey applicable traffic laws, use
good judgment, and select a safe follow­
ing d istance for the traff ic, road and
weather conditions .
(D Tips
-Distance 3 is set automatically each time
you switch the ignition on.
- Your standard settings are automatically
stored and assigned to the remote con­
trol key being used.
