@) Note
— Auxiliary headlights and other accessories in
front of the air intake impair the cooling ef-
fect of the coolant. This increases the risk of
the engine overheating during high outside
temperatures and heavy engine load.
— The front spoiler also helps to distribute
cooling air correctly while driving. If the
spoiler is damaged, the cooling effect will
be impaired and the risk of the engine over-
heating will increase. See an authorized
Audi dealer or authorized Audi Service Fa-
cility for assistance.
Tachometer
The tachometer (2) > page 10, fig. 3 displays the
engine speed in revolutions per minute (RPM).
The beginning of the red zone in the tachometer
indicates the maximum permissible engine speed
for all gears once the engine has been broken in.
Before reaching the red zone, you should shift in-
to the next higher gear, choose the "D" or "S" se-
lector lever position, or remove your foot from
the accelerator pedal.
Engine speed limitation
Applies to: vehicles with center armrest
If the BB indicator light turns on, the engine will
be automatically limited to the RPM displayed in
the instrument cluster. This will protect the en-
gine components, for example during a cold start
or 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-
al once.
If the engine speed limitation was activated by an
engine control malfunction, the B§ indicator
light also turns on. Make sure the engine speed
does not go above the speed displayed, for exam-
ple when downshifting. Drive to an authorized
Audi dealer or authorized Audi Service Facility im-
mediately to have the malfunction corrected.
CG) Note
The needle in the tachometer may only be in
the red area of the gauge for a short period of
time before there is a risk of damaging the
engine. The location where the red zone be-
gins varies depending on the engine.
Odometer
11:30"

Fig. 4 Instrument cluster: odometer and reset button
The trip odometer and odometer are displayed in
the status line ©) > page 10, fig. 3.
The trip odometer shows the distance driven
since it was last reset. It can be used to measure
short distances. The odometer shows the total
distance that the vehicle has been driven.
Resetting the trip odometer

> Press the reset button [0-0] on the instrument
cluster. The trip odometer will be reset to zero.
(i) Tips
Distances are displayed in mi (miles) or km
(kilometers).

Outside temperature
display
The outside temperature is displayed in the sta-
tus line ©) > page 10, fig. 3.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the motor.

The following light functions are available de-
pending on vehicle equipment and only function
when the light switch is in the AUTO position.
Static cornering light* (vehicles with LED head-
lights) - the cornering light switches on automat-
ically when the steering wheel is turned at a cer-
tain angle at speeds up to approximately 44 mph
(70 km/h) and when the turn signal is activated
at speeds up to approximately 25 mph
(40 km/h). The area to the side of the vehicle is
illuminated better when turning.
Highway light function* (vehicles with LED head-
lights) - This function adapts the lighting for
highway driving based on vehicle speed.
Speed dependent light distribution* (vehicles
with LED headlights) - The speed dependent light
distribution adapts the light in towns and on
highways or expressways. Intersections can also
be illuminated on vehicles with a navigation sys-
tem*.
ZA WARNING
— Automatic headlights* are only intended to
assist the driver. The driver is still responsi-
ble for controlling the headlights and may
need to switch them on and off manually
depending on light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams under these weather conditions and
when driving in the dark ZO. >

—To reduce glare for traffic behind your vehi-
cle, the rear fog lights* should only be
turned on in accordance with the legal regu-
lations in the country where you are operat-
ing the vehicle.
— If the battery has been discharging for a
while, the parking light may switch off auto-
matically. Always make sure your vehicle is
parked and adequately illuminated accord-
ing to the legal regulations in the country
where you are operating the vehicle. Avoid
using the parking lights for several hours.
G) Tips

justed > page 37.
— In some markets, the tail lights will switch
on when the daytime running lights switch
on.

—In cool or damp weather, the inside of the
headlights, turn signals, and tail lights can
fog over due to the temperature difference
between the inside and outside. They will
clear shortly after switching them on. This
does not affect the service life of the light-
ing.

function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
The mirror surfaces tilt slightly when reverse
gear is selected to provide a better view, for ex-
ample of the edge of the curb.
You can adjust the mirror surface by turning the

Z\ WARNING
Curved mirror surfaces (convex) enlarge the
field of vision. However, they make objects in
the mirror appear smaller and farther away.
When using these mirrors to estimate your
distance to vehicles behind you when chang-
ing lanes, you could estimate incorrectly,
which increases the risk of an accident.

@) Note
If the mirror housing was moved by force (for
example, by running into an object when ma-
neuvering the vehicle), the mirror must be
folded all the way in using the power folding
function. The mirror housing must not be
moved back into place by hand because this
could impair the function of the mirror mech-
anism.
@ Tips
If the power adjusting function malfunctions,
the glass in both mirrors can be adjusted by
pressing on the edge of it by hand.

conscious, flush the mouth with water for at
least 15 minutes. Do not induce vomiting
unless this is recommended by medical pro-
fessionals. Seek medical attention immedi-
ately.
() Note
If the glass on an automatic dimming mirror
breaks, electrolyte can leak out. This liquid
damages plastic surfaces. Clean this liquid as
quickly as possible, for example with a wet
sponge.
