ty immediately to have the malfunction correct-
ed.
@) 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


Fig. 7 Instrument cluster: reset button
The trip odometer and odometer are displayed in
the status bar @) > page 11.
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
> To reset the trip odometer to zero, press the re-
set button @.
@® Tips
Distances are displayed in mi (miles) or km
(kilometers).
Outside temperature
display
The outside temperature is displayed in the sta-
tus bar @) 9 page 11.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed in
14
the instrument cluster may be slightly higher
than the actual temperature outside due to heat
radiating from the motor.
At temperatures below 41 °F (+5 °C), a snowflake
symbol appears in front of the temperature dis-
play > A\.

ZA WARNING
Do not assume the roads are free of ice based
on the outside temperature display. Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+5 °C)
and that ice can increase the risk of accidents.

Engine oil temperature
indicator
Applies to: vehicles with engine oil temperature indicator
Depending on the vehicle equipment, the engine
oil temperature %7 may be indicated by a bar in
the instrument cluster.
» Applies to: vehicles with Audi virtual cockpit:
Open the vehicle functions tab and switch to
the desired view > page 12.
> Applies to: vehicles with analog instrument
cluster: Open the lap timer > page 121.
When engine oil temperatures are low, the dis-
play --- °F (--- °C) appears in the instrument clus-
ter. The engine has reached its operating temper-
ature when the engine oil temperature is be-
tween 176 °F (80 °C) and 248 °F (120 °C) under
normal driving conditions. The engine oil temper-
ature may be higher if there is heavy engine load
and high temperatures outside. This is not a
cause for concern as long as the Ei => page 217
or & = page 217 indicator lights do not turn on.
Boost indicator
Applies to: vehicles with boost indicator
Depending on vehicle equipment, the current en-
gine load (meaning the current boost pressure)
may be indicated by a bar in the instrument clus-
ter.

@ All-weather lights &
Requirement: the light switch must be in the AU-
TO or ZO position.
The headlights automatically adjust so that there
will be less glare, for example when the road sur-
face is wet.
Automatic headlight range control
Your vehicle is equipped with automatic head-
light range control. It reduces glare for oncoming
traffic if the vehicle load changes. The headlight
range adjusts automatically.
Audi adaptive light
Applies to: vehicles with adaptive light
Audi adaptive light provides better visibility when
driving in the dark. The lights are adapted to the
48

road conditions based on speed, such as when
driving on expressways, rural roads, at intersec-
tions, and around curves. The adaptive lights only
function when the light switch is in the AUTO po-
sition and the all-weather lights are switched off.

ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Automatic headlights are only intended to
assist the driver. They do not relieve the
driver of responsibility to check the head-
lights and to turn them on manually based
on the current light and visibility conditions.
For example, fog cannot be detected by the
light sensors. So always switch on the low
beams ZO under these weather conditions

and when driving in the dark.

@) Tips
— If the vehicle battery has been discharging
for a while, the parking light may switch off
automatically. Avoid using the parking
lights for several hours.
— Follow the regulations applicable to the
country where you are operating the vehicle
when stopping the vehicle and when using
the lighting systems.
—Awarning tone will sound if you open the
door when the exterior lights are switched
on.

daytime running lights are switched on*. In
vehicles in certain markets, the tail lights
will also turn on.
—Incool 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.

switched on. The respective a or B indicator
light flashes.
@ Right turn signal
@® Left turn signal
The turn signal blinks three times if you tap the

Q/ ®- Selects the left or right exterior mirror.
To adjust the mirror glass in a mirror, press the
knob in the desired direction.
GR - Heats the mirror glass depending on the out-
side temperature.
S) - Folds the exterior mirrors*. To fold the mir-
rors out, turn the knob to one of the other posi-
tions. In the MMI, you can select if the mirrors
fold in automatically when you lock the vehicle
> page 31.
Front passenger&#39;s exterior mirror tilt
function*
Requirement: the knob must be in the position
for the front passenger’s exterior mirror.
To help you see the curb when backing into a
parking space, the surface of the mirror will tilt
slightly when reverse gear is selected.
You can adjust the mirror surface by turning the
knob in the desired direction.
The mirror moves from the reversing position
back to the original position:
— When you switch the ignition off
— Once you drive forward at speeds faster than 9
mph (15 km/h)
— When the knob is no longer in the position for
the front passenger exterior mirror

Z\ WARNING
Curved mirror surfaces (for example convex)
enlarge the field of vision. However, they
make objects in the mirror appear smaller and
farther away. When using these mirrors to es-
timate your distance to vehicles behind you
when changing lanes, you could estimate in-
correctly, which increases the risk of an acci-
dent.

@) Note
— Applies to: vehicles with power folding exte-
rior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must use the pow-
er folding function to fold the mirror all the
way out. The mirrors will make a loud noise
when they latch into place. The mirror hous-
ing must not be moved back into place by
hand because this could impair the function
of the mirror mechanism.
— Applies to: vehicles without power folding
exterior mirrors: If the mirror housing was
moved by outside forces (such as an impact
when maneuvering), you must move it back
in place by hand.
— If you wash the vehicle in an automatic car
wash, you must fold the exterior mirrors in
to reduce the risk of damage to the mirrors.
Never fold power folding exterior mirrors*
by hand. Only fold them in and out using
the power controls.
@) Tips
—If the power adjusting function malfunc-
tions, the glass in both mirrors can be ad-
justed by pressing on the edge of it by hand.
— Certain settings are automatically stored
and assigned to the active user.
Dimming the mirrors
Manual dimming rearview mirror
> Pull the lever on the bottom of the mirror back.
Automatic dimming rearview mirror*
> The interior and exterior mirrors* dim automat-
ically when light shines on them, for example
from headlights on a vehicle behind you.

Z\ WARNING
— If the glass on an automatic dimming mir-
ror* breaks, electrolyte can leak out. This
liquid can irritate the skin, eyes and respira-
tory system. If there is contact with the flu-
id, flush immediately with plenty of water.
Consult a physician if necessary.
— Repeated or long-term exposure to electro-
lyte fluid can lead to irritation of the air-
ways, especially in people with asthma or
other respiratory conditions. Take deep >
