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.
& WARNING
Reduced visibility is dangerous and can cause accidents .
• For safe driving it is very important that all windows be free of
ice, snow and condensation.
• Fully familiarize yourself with the proper use and function of
the heating and ventilation system and especially how to defog
and defrost the windows.
• Never use the windshield wiper/washer system in freezing
weather until you have warmed the windshield first, using the
heating and ventilation system. The washer solution may freeze
on the windshield and reduce visibility.
0 Note
• If you suspect that the air conditioner has been damaged, switch
on ECON and contact an authorized Audi dealer to have the system
inspected.
• Repairs to the Audi air conditioner require special technical
knowledge and special tools. Contact an authorized Audi dealer for
assistance.
[ i] Tips
• Keep the air intake slots (in front of the windshield) free from ice,
snow and debris in order to maintain the proper function of the
climate control system.
• Air escapes through vents under the rear window. When placing
items of clothing on the luggage compartment cover, ensure that
the openings are not covered.
Controls and equip ­
ment
• If the inside temperature is very high (for example, if the vehicle
has been parked in sun), open the windows and allow the hot air to
escape before turning on the air conditioner. •

Starting and stopping the engine
Starting the engine
The engine can only be started with your original Audi
key.
- Set the parking brake.
- Move the selector lever to the neutral position (automatic
transmission: selector lever in P or N)
=> &.
- On vehicles with manual transmission, fully depress the
clutch pedal.
- Turn the ignition key to position
0 => page 119, fig. 136
- do not depress the gas pedal when starting the engine!
- Let go of the key as soon as the engine starts.
A cold engine may at first be loud after it has been started. This is
due to the hydraulic valves building up the oil pressure. This normal
and no need for concern.
If the engine does not start immediately, stop trying after 10
seconds and then try to restart the engine about 30 seconds later.
What to do if the engine does not start
• ~ page 304, "Starting with jumper cables"
• ~ page 306, "Emergency towing with commercial tow truck".
& WARNING
Never start or let the engine run in a confined or enclosed area .
Exhaust fumes from the engine contain carbon monoxide, a color­
less and odorless gas. Carbon monoxide can be fatal if inhaled.
• Never leave the engine idling unattended. An unattended
vehicle with a running engine poses a danger of personal injury or
theft.
0 Note
• Avoid high engine speeds, fast acceleration or heavy engine
loads while the engine is still cold. This could damage the engine.
• The engine cannot be started by pushing or towing the vehicle.
~ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emis­
sions, do not let your vehicle stand and warm up. Be ready to drive
off immediately after starting your vehicle. Maintain moderate
speed until the engine is completely warm. Remember, the engine
performs best at operating temperature.•
Stopping the engine
- Turn the ignition key to position (D => page 119, fig. 136.
& WARNING
• Never turn off the engine until the vehicle has come to a
complete stop.
• The brake booster and servotronic only work when the engine
is running . With the ignition turned off, you have to apply more
force when steering or braking. Since you cannot steer and stop
normally, this can lead to accidents and serious injuries.
• The radiator fan can continue to run for up to 10 minutes even
after you have turned off the engine and removed the ignition key.
The radiator fan can also turn on again if the engine coolant heats
up because of intense sunlight or heat build-up
in the engine
compartment. _,.

Acoustic park assist
A pplies to vehicles : with 4 -ch an nel a co ustic park ass is t
Rear acoustic park assist
The rear acoustic park assist warns you of obstacles or
objects behind your car.
How it works
The acoustic park assist warning system (4-channel acoustic park
assist) uses ultr asonic sensors to warn yo u when you are
backing
your vehicle close to an obstacle . The system 's 4 sensors are located
inside the rear bumper .
Acti va ting
The rear acoustic park assist is ac tivated whenever you shift into
Reverse . You will hear a warn ing tone when the system is on .
Reverse
With the car backing up in reverse gear, the col lision warning sound
sets in at the fol lowing
approximate d istances to obstacles :
straight aft 5ft(1.5m)
angling aft off vehicle corners 2 ft (0
.6 m)
As the dis tance shr inks, the time interva l between the audible tones
grows shorter.
The sound changes to a continuous tone as soon as the remaining distance to an obstacle closes to less than about 1 ft. (0 .3 ml. The
steady tone cautions you that you have backed up hazardously
close and you ris k co llision by backing up any further .
Malfunctions in the system
If a warning tone is audible for about five seconds when you turn on
the ignit ion, there is a malfunction in the system . Have the prob lem
corrected by your authorized Audi dea ler. _,.
