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 22.
@ 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.
{D Tips
Applies to: vehicles with diesel engines
Due to the high efficiency of these engines,
the engine may not always reach operating
temperature in cold outside temperatures.
This is normal and not a cause for concern.
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.
Before reaching this zone, you should shift into
the next highest gear, select the "D/S" selector
lever position, or remove your foot from the ac ­
celerator pedal.
@ Note

Climate control system
Description
A pp lies to: ve hicles w ith 3 -zo ne del uxe automatic c limate
co ntrol or 4-zo ne de luxe au tomatic cl imate co ntrol
The climate control system warms, cools and re­
moves humidity from the air in the vehicle interi­
or.
It is the most effective when the windows and
sunroof* are closed . If there is a bu ild-up of heat
inside the vehicle, ventilat ion can he lp to speed
up the cooling process.
In all heating mode functions except for
defrost,
the blower on ly switches to a h igher speed once
the engine coolant has reached a suffic ient tem­
perature.
Pollut ant filt er
The pollutant filter removes pollutants such as
dust and pollen from the a ir .
K ey recognit ion
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .

@ For the sake of the environment
- If you would like to reduce fuel consump­
t ion, sw itch the air conditioning off. This
will also reduce emissions.
- In vehicles with a diesel engine, you can
switch the auxiliary heater off in the Info­
tainment system.
(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
front of the windshield must be free of ice,
snow or leaves.
- Condensation from the cooling system can
dr ip and form a puddle of water under the
vehicle . This is normal and does not mean
there is a leak.
- The energy management system may tem­ porarily switch off certain functions, such as
the seat heating* or rear window defogger.
T hese systems are ava ilable again as soon
as the ene rgy supply has been restored.

Trail er to wing
If you have to drive th rough diffic ult road condi­
tions, you can raise the vehicle again after hitch ­
ing the trai ler or after adjust ing the tongue
weight .
{QJ Note
Applies to: vehicles with air suspension
-Changes in temperature or load can affect
the he ight of the vehicle.
- Set the a ir suspension to the standard vehi­
cle heig ht, otherwise the applicab le tongue
weig ht 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 frequently.
- Avo id driving wit h a trailer du ring the vehi­
cle break-i n period .
Driving with a trailer
Driving with a trailer requires extra caution.
Speed
Adhere to the legal speed l imi ts. Follow t he lega l
regulations specif ic to the country.
As the speed inc reases, the d riving stability of
the t railer dec reases . The refore you sho uld not
exceed t he max imum legal speed limit when
there are unfavorable road, weather and/or wind
conditions. This especially applies when driving
downhill.
You must a lways reduce yo ur speed as soon as
you not ice even the s lightest swinging motion of
the trailer . Never try to "straighten out" the trail ­
er by accelerating.
The weig ht dis trib ution is very poo r if t he ve hicle
is empty and the trailer is loaded. However if you
must drive under these circumstances, t hen drive
especia lly slowly.

Brak es
Brake in a time ly manner. Downs hift be fo re dr iv ­
i ng down hill so that the engine can assist with
braking ~&, .
When using a t railer w it h over run bra kes, fi rst
brake ge ntly t hen q uickl y. This red uces the r isk o f
jerking while braking if the trailer wheels lock up .
Engine coolant temperatur e
Pay attention specifically to the coolant tempera­
ture display when there a re high outs ide temper­
at ures , and whe n driving on long i nclines
~ page 11. Shift to a highe r gear in a t imely man­
ner .
A WARNING
Constant braking causes the b rakes to over­
h eat and substantially reduces bra king per ­
formance, increases b raking distance o r caus­
es complete failure of the brake system.

- Select the "P" selector lever posit ion .
- Let the engine cool down.
- Never open the hood when there is steam or coolant escaping from the eng ine compart­
ment, because there is a risk that you could
be burned . Wait until no steam or coolant is
escaping.
- Keep children away from the engine com­
partment .
- Never spill flu ids on a hot engine. These flu­
ids (such as the anti -freezing agent con­
tained in the coolant) can ignite .
- Avoid short circu its in the electrical system .
- When working in the engine compartment,
remember that the radiator fan can sw itch
on even if the ign ition is switched off, which
increases the risk of injury .
- Never open the cap on the coolant expan­
sion tank when the eng ine is warm. The
cooling system is under pressure .
- To protect your face, hands, and arms from hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any circumstances . This increases the risk of
burns.
- If tests need to be performed w ith the en­
gine running, there is additional danger due
to moving components (such as the ribbed
Ch eck ing and F illing
be lt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances activate the
throttle inadvertently (for example, by hand
from the engine compartment) if the veh i­
cle is stat ionary but the eng ine is running
and a gear is engaged . Otherwise, the veh i­
cle will start to move immed iately and this
could result in an acc ident.
- Pay attent ion to the following warnings
when work on the fue l system is required :
- Do not smoke .
- Never wor k nea r open flames .
- Always have a working fi re extingu isher
nearby.
- All work on the battery or electrical system
in your veh icle can result in inju ries, chemi­
cal burns, acc iden ts or bu rns . Because of
this, all work m ust be performed
onl y by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk o f electric shock and in ­
jury, never touch the following components
when the engine is running or is being start­
ed:
- Ign it ion cable
- Other components in the electronic high -
voltage ign ition system
- If you must check or perform work on the
engine wh ile it is running:
- Set the parking brake first and then se lect
the "P" selector lever position .
- Always proceed w ith extreme caution so
that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can hang down into the engine .
- lim it your exposure to exhaust and chemi­
cals to as short a time as possible
