Engine coolant temperature gauge
The engine coo lant gauge ~ fig . 2 © only works when the ignition is
on. To p revent damage to yo ur engine, ple ase note the following
important po ints:
Engine cold
As long as the needle rema ins at or close to the bottom of the gauge,
t he engine s till has not rea ched its operat ing tem perature. Avo id high
eng ine speeds, heavy eng ine loads and heavy t hrottle app lications.
Normal temperature
When the eng ine has reached its ope rating temperature, the needle
w ill move into the midd le of the gauge and remain t he re.
If the
eng ine is working hard at high outs ide temperatures, the needle may
r ise up. This is no need to worry as long as the
_t_ warning light in th e
instr ument cluster does not illuminate.
Warning light in the instrument cluster -t
When the _L warning light in the instrument cluster starts to flash,
this can mean one of two things: e ithe r th e coolan t
temperature is
too high, or the coolant
level is too low=> page 35. _,.

If the needle is well in the upper area of the gauge, the coolant
tempe rat ure is too high.
Stop the vehicle , switch the engine off and
allow the engine to cool.
If the warning light comes on again after
driving a short distance, contact an authorized dealer.
& WARNING
• Alway s observe th e warning in=> page 290 , "Engine comp art ­
ment ", before opening the hood and checking the engine coolant
level.
• Never open the engine hood if you see or hear steam, or if you
s ee engin e coolant dripping from the engine compartment. You
could burn yourself. Let the engine cool off first so that you cannot
hear or see any steam or engine coolant .
0 Note
• Mounting additiona l lights or accessories in fron t of the a ir inlets
reduces the cooling effect of the radiator . At high outside tempera­
t ur es o r high engine load, the engine could overheat.
• The front spo iler has bee n des igned to prope rly d istribute the
coo ling air when the vehicle is moving.
If the spoiler is damaged, this
cou ld reduce the coo ling effect and the eng ine could then overheat .
Ask your author ized A udi dealer for assistance .•

Engine cooling system malfunction _
t_
A malfunction in the engine cooling system must be
repaired as soon as possible.
When the -L symbol in the display blinks, then either the
engine coolant
temperature is too high, or the coolant level
is too low. An additional driver message can also be displayed
by pressing the [CHECK] button:
Switch off engine and check coolant level
- Pull off the road .
- Stop the vehicle.
- Turn off the engine.
- Check coolant level :::>

-Add coolant if necessary=> page 310.
-Continue driving only after the engine coolant
warning/indicator light goes out.
- Contact your authorized Audi dealer for assistance if
necessary.
If the engine coolant level is correct, then the radiator fan may be the
cause of the malfunction.
If the O warning symbol (alternator malfunction) also lights up on
the instrument panel:::::,
page 34, then the fan belt may be damaged .
& WARNING
• If your vehicle should break down for mechanical or other
reasons, park at a safe distance from moving traffic, turn off the
engine and turn on the hazard warning lights:::::,

escaping.
• The engine compartment of any vehicle is a dangerous area.
Before you perform any work in the engine compartment, turn of
the engine and allow it to cool. Follow the warning stickers
=> page 290, "Engine compartment".
0 Note
Do not continue driving if the_¥_ symbol illuminates. There is a
malfunction in the engine cooling system -you could damage your
engine. •
Engine oil pressure malfunction 't:::f:
The red engine oil pressure warning symbol requires
immediate service or repair. Driving with a low-oil-pres­
sure indication is likely to inflict severe damage to the
engine.
If the ~ symbol appears in the display and blinks, the oil
pressure is too low. An additional driver message can also be
displayed by pressing the
[CHECK] button :
Switch off engine! Oil pressure too low
Immediate actions
- Pull off the road.
- Stop the vehicle.
- Turn off the engine .
-Check the engine oil level with the dipstick => page 305.
Dipstick readings checks too low
- Top off oil to the proper level=> page 306 .
Make sure that the oil pressure warning symbol~
appears no longer in the display before you start driving
again.
Dipstick reading checks OK
- If the oil pressure warning symbol ~ starts flashing
again even though the engine oil level checks OK on the
dipstick,
do not continue driving and do not let the
engine run in idle.
Instead, contact your authorized Audi
dealer for assistance.
[I) Tips
• The engine oil pressure symbol~ is not an indicator for a low
engine oil level. Do not rely on it. Instead, check the oil level in your
engine at regular intervals, preferably each time you refuel, and
always before going on a long trip.
• The yellow oil level warning indication
~ requires oil refill or
workshop service without delay. Do not wait until the red oil pres­
sure warning ~ starts to flash before you respond to the low oil
level warning
..'!' . By then, your engine may already have suffered
serious damage. •

Warm and cold
Climate control
Description
The air conditioner is fully automatic and is designed to
maintain a comfortable and uniform climate inside the
vehicle.
We recommend the following settings:
- Set the temperature to 72
°F (+22 °C).
- Press the
[AUTO] button.
With this setting, you attain maximum comfort in the least amount
of time. Change this setting , as desired , to meet your personal needs.
The climate controls are a combination of heating, ventilation and cooling systems, which automatically reduce humidity and cool the
air inside your vehicle .
The air temperature, air flow and air distribution are automatically regulated to achieve and maintain the desired passenger compart­
ment temperature as quickly as possible.
The system automatically compensates for changes in outside
temperature and for the intensity of the sunlight entering the
vehicle. We recommend you use the
Automatic mode ~ page 114
for year-round comfort .
Please note the following:
Turn on the air conditioner to reduce humidity in the vehicle. This also
prevents the windows from fogging up.
When the outside temperature is high and the air is very humid,
condensation from the evaporator may drip under the vehicle . This is
normal and does not indicate a leak.
Controls and equip ­
ment Safety first
If the outside temperature is
low, the fan normally only switches to a
higher speed once the engine coolant has warmed up sufficiently .
The air conditioner temporarily switches off when you drive off from
a standstill using full throttle to save engine power.
The compressor also switches off if the coolant temperature is too
high, so that the engine can be adequately cooled under extreme
loads.
Air pollutants filter
The air pollutants filter (a combined particle filter and activated char­
coal filter) reduces or prevents outside air pollution (dust, or pollen)
from entering the vehicle. The air is also filtered in air recirculation
mode.
The air pollutants filter must be changed at the intervals specified in
your Warranty
& Maintenance booklet, so that the air conditioner can
properly work.
If you drive your vehicle in an area with high air pollution, the filter
may need to be changed more frequently than specified in your Audi
Warranty
& Maintenance booklet. If in doubt, ask your authorized
Audi Service Advisor for advice .
Key coded settings
The air conditioner settings selected are automatically stored and
assigned to the key being used. When the vehicle is started, the air
conditioner automatically selects the settings assigned to that key.
This way every driver will maintain his/her own personal settings and
does not have to reset them manually.
If a different driver uses your key and changes the air conditioner
settings, the latest adjustments will erase and replace the settings
you have stored. _.,
