A 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 .
(D Tips
-Depending on vehicle equipment, the in­
strument illumination (needles and gauges) may turn on when the lights are off and the
ignition is switched on . The illumination for
the gauges reduces automatically and even­
tually turns off as brightness outside in­
creases. This function reminds the driver to
turn the low beams on at the appropriate
time.
- You can select the units used for tempera­
ture, speed and other measurements in the
Infotainment
system ¢ page 245.
-If your vehicle is stationary or if you are driv­
ing at very low speeds, the temperature dis­
played may be slightly higher than the ac­
tual temperature outside due to the heat ra­
diating from the engine.
- At temperatures below 41 °F (+5 °C), a
snowflake symbol appears in front of the
temperature
display ¢,&. .
Coolant temperature indicator
The coolant temperature display @¢ page 10,
fig . 3
or ¢ page 10, fig . 4 only functions when
the ignition is switched on. To prevent engine
damage, please observe the following notes
about the temperature ranges.
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­ perature yet . Avoid high engine speeds, full ac­
celeration and heavy engine loads.
Cockpit overview
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 display turns on, the coolant tem­
perature is too
high ¢ page 23.
@ Note
-Auxiliary headlights and other accessories in
front of the cooling-air intake impair the
cooling effect of the coolant. This increases
the risk of the engine overheating during
high outside temperatures and heavy en­
gine 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 displays the engine speed in rev­
olutions 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
and when it is warmed up to operating tempera­
ture. Before reaching this zone, you should shift
into the next highest gear, select the "D/S" selec­
tor lever position, or remove your foot from the
acce lerato r pedal.
@ Note
The needle in the tachometer @¢ page 10,
fig. 3
or ¢ page 10, fig. 4 may only be in the
red area of the gauge for a short time or there
is a risk of engine damage . The location where
the red zone begins varies depending on the
engine.
@) For the sake of the environment
Upshifting early helps you to save fuel and re­
duces operating noise.

Warm and cold Climate control system
Description
The climate control system warms , cools and re­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed . If there is a bu ild -up of heat
inside the ve hicle, ventilation can he lp to speed
up the cooling process.
I n all he ating mode f unct ions except for
defrost ,
the blower on ly switches to a higher speed once
the engine coolant has reached a sufficient tem ­
perature .
Pollutant filter
The pollutant filte r removes pollutants such as
d ust and pollen from the a ir.
Key recognition
The climate control settings are automatically
sto red and assig ned to the remote control key
that is i n use .
Warm and c old
@ For the sake of the environment
If you wo uld like to reduce fue l consumption,
switch the air conditioning off. T his w ill also
r educe em issions.
(D Tips
- To prevent interference with the heating
and cooling output and to prevent the win ­
dows from fogging over, the a ir intake in
fro nt of the w indshie ld must be free of ice,
snow o r leaves .
- Condensation from the coo ling system can
dr ip and form a pudd le of water under the
veh icle . Th is is norma l and does not mean
t here is a lea k.
- The e nergy management system may tem­
pora rily switch off certa in functions, s uch as
the seat heati ng* o r rear window defogger .
Th ese sys tems are av ailable aga in as soon
as t he e nergy supply has been restore d.

SYNC Syn chr oniz ation
Use t he rocker sw itc h® to select the f unct ion.
When synchronization is switched on, the set­
tings for the driver's side are applied to the front
passenger's side and the rear (except for seat
heating/venti lation*). When the settings on the
front passenger's side or in the rear are changed,
the synchron izat ion is automatically switched off
and
3 -z one appears in the display .
SET REAR function
Use the rocker switch ® to select the function .
When the function is switched on, you can adjust
all settings for the rear us ing the climate control
system controls in the cockpit . The rear climate
control system controls cannot be operated at
the same time . T his function switches off auto­
mat ica lly after a ce rtain per iod of t ime or after
leav ing the menu.
Vents
You can open or close the center and rear vents in
the cockpit and the vents in the rear center con­
sole us ing the r idged thumbwhee ls . T he levers
adjust the d irection of the airflow from the vents.
Re sidu al he at
You can activate the residual heat function when
the ignition is switched off by pressing the knob
(!) . The res idual heat from the coolant is used to
heat the vehicle interior. The residual heat func­
tion switches off automatically afte r about 15
m inutes.
A WARNING
- Yo u should not use the re circulation mode
for an extended period of time, because no
fres h air is drawn in and the windows can
fog when cooling mode is sw itched off. This
increases the risk of an accident.
- Individuals with reduced sensitivity to pain
or temperature cou ld deve lop burns when
using the seat heating* funct ion. To reduce
the risk of injury, these ind iv iduals should
not use seat heati ng*.

Trail er to wing
Trailer towing
Driving with a trailer
General information
Your veh icle is primari ly intended for transport­
ing peop le and luggage. Howeve r, if you dr ive
with a tra iler , follow the techn ica l requirements ,
the operation and driving tips, and the lega l reg ­
ulations.
Dr iving w ith a trailer affects the vehicle 's fuel
consumpt ion, performance and wear. It a lso re­
quires higher concentration from the driver .
A WARNING
Do not transport any people in a trailer due to
the risk of fatal injury .
Technical requirements
Certain requirements must be met when towing
a trailer.
Trailer hitch
Only use a trailer hitch with a removab le ball
h itch mount and ball h itch. The tra ile r hitc h must
be pe rm it t ed for the vehicle, the tra iler and the
permitted tota l weight of the trailer being
pu lled . Above all, it must be secure ly and safe ly
attached to the vehicle trailer.
Never mo unt a t rai ler hitch on the bumper. The
trai ler hitc h must be mounted in a way that does
not impair the function of the bumper. Do not
make any changes to the exhaust system and the
brake system.
Check regu larly if the trai ler hitc h is securely
mounted . A lways follow the instructions given by
the trai ler hitch manufacturer .
Trailer brakes
If t he tra ile r has its own bra ke system, then fol­
low the manufacturer specifica tions. Howeve r,
the brake system on the trai ler must never be
connected to the vehicle brake system.
92
Engine cooling system
D riving w ith a tra ile r means a higher load on t he
engine and the cooling sys tem. The coo ling sys­
tem must be designed for additiona l load and
contain enoug h
coolant ~@ .
A WARNING -
- Never mount a "weight -distributing" or
"load-balancing" trailer coupler as the trail­
er hitch. The ve hicle was not des igned for
these types of tra iler h itches. The tra iler
h itch can malfunction and t he tra ile r can
b reak off from the vehicle.
- If t he tra ile r i s equ ipped w ith elect ronic
brakes, these brakes can not be activated by
a facto ry-installed control system, whi ch in­
creases the r isk of an accide nt.
- To red uce the r is k of injury, always remove
the ball hitch mount if no tra ile r is mo unt ­
ed.
@ Note
L onge r incl ines cannot be dr iven without a
su itab le cooli ng system, especially if the out­
s ide temperatu res a re high. ot herwise, this
i nc reases the risk of eng ine da mage.
Operating instructions
Several things must be noted when towing a
trailer.
Towing capacity
The permitted towing capacity must not be ex ­
ceeded under any
circumstances ~ page 370.
You can dr ive up larger inclines if you are not us­
i ng the maximum towing capacity.
The towing capacities given only apply to e leva ­
tions up to 3,200 ft (1,000 m) above sea level. As
the e levation increases, the engine power de­
creases due to the decreasing air pressures. T his
reduces the hill climb ing ability and towing ca­
pac ity . For every additional 3,200
ft (1,000 m),
t h e maximum permitted tow ing weight must be
r educed by app roximately 10% . T he pe rm itted
tow ing weight is t he comb ined we igh t of the
( loaded) vehicle and the (loaded) trailer .

Trail er to wing
- Set the a ir suspension to the standard vehi ­
cle height, otherwise the applicab le tongue
weight no longer applies to your vehicle.
(D Tips
- Use chocks when parking on incl ines if the
trailer is loaded .
- We recommend also having the vehicle in­
spected between the inspection intervals if
you are towing a trai ler frequent ly .
- Avo id driving with a trailer d uring the vehi ­
cle break-in period .
Driving with a trailer
Driving with a trailer requires extra caution .
Speed
Adhere to the legal speed limits. Follow the legal
regulat ions spec ific to the country.
As the speed increases, the driving stability of
the trailer decreases . Therefore you should not
exceed the maximum legal speed l imit whe n
there a re unfavorabl e road, weathe r and/or wind
conditions. This especially appl ies when dr iv ing
downhill.
You must always reduce you r speed as soon as
you not ice even the s lightest sw inging motion of
the t railer. Neve r try to "straighte n ou t" the t rail­
e r by accelera ting.
The weight distribution is very poor if t he veh icle
is empty and the t railer is loaded . H oweve r if you
m ust dr ive under these c ircumstances, t hen d rive
espec ially slowly.
Brakes
Brake in a t imely manner . Downshift before driv­
i n g downhill so that the engine can assist w ith
b raking
¢ ,&. .
When us ing a tra iler with overrun brakes, first
brake gently then qu ickly . This reduces the risk of
je rk ing w hile brak ing if the tra ile r w heels lock up .
Engine coolant temperature
Pay attention specif ica lly to the coolant tempera­
ture display when there are h igh outside tempe r­
atures, and when dr iv ing o n long inclines
94
¢ page 11. Shift to a higher gear in a timely man­
ner .
A WARNING
Constant braking causes the brakes to over­
heat and substantially reduces braking per­
formance, increases braking distance or caus­
es complete failure of the brake system.

- Never open the hood when there is steam or
coo lant escaping from the engine compart­
ment, because there is a risk that you could
be burned . Wait unt il no steam or coolant is
escaping.
- Keep children away from the eng ine com­
partment .
- Never sp ill fluids on a hot engine . These flu­
ids (such as the anti-freezing agent con­
tained in the coolant) can ignite .
- Avoid short c ircuits in the electrical system.
- When working in the engine compartment, remember that the radiator fan can switch
on even if the ignition is switched off, wh ich
increases the r isk of injury .
- Never open the cap on the coolant expan­
sion tank when the engine is warm . The
cool ing system is under pressure .
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap w ith a
large cloth when open ing.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns .
- If tests need to be performed with the en­
gine runni ng, there is add itiona l danger due
to mov ing components (such as the r ibbed
be lt, alte rnato r and rad iato r fan) and from
the hig h-voltage ignition system.
- Do not unde r any ci rcumstances activate the
throttle inadvertent ly (for example, by hand
from the engine compartment) if the veh i­
cle is stationary but the engine is running
and a gear is engaged. Otherwise, the vehi ­
cle will start to move immediate ly and this
could result in an acc ident.
- Pay attention to the following warnings
when work on the fue l system is required:
- Do not smoke.
- Never work near open flames .
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system in your vehicle can result in injuries, chemi­
cal burns, acc idents or burns . Because of
this, all work must be performed
only by an
author ized Audi dealer or author ized Audi
