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. •
Controls
This overview will help you to familiarize yourself with the
air conditioning controls.

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. _,.

~ehicle care Technical data

On the road ------------------------------.J
Keep the sensors in the rear bumper clean and free from ice so that
the acoustic park assist system can function properly.
& WARNING
• Sensors have dead spaces in which objects cannot be
detected . Be especially alert for small children and animals, since
they are not always detected by the sensors.
• The acoustic park assist system is not a substitute for the
driver's own caution and alertness. Ultimate responsibility always
remains with the driver during parking and similar maneuvers .
Always watch where you are driving.
0 Note
• Remember that low obstacles for which a warning has already
been issued may "dive" below the system's sensing zone if the
vehicle is being backed up closer. In this case, the warning sound
shutting off does
not indicate that you have cleared the obstacle .
Instead, impact is imminent.
• Objects such as trailer hitches, barrier chains, narrow posts or
fences covered by a thin layer of paint may not always be detected
by the system . They can still damage your vehicle without a
warning.
[ i] Tips
Keep the sensors in the rear bumper clean and free of snow and ice
so that the acoustic parking assist system can function properly. •

Cruise control
General information
The cruise control system allows you to maintain a
constant speed.
The cruise control system allows you to maintain a constant driving
speed when driving faster than 18 mph (30 km/h) -to the extent this
is possible with the given engine power and braking characteristics .
This allows you to take your foot off the "gas" and rest it, especially
on long trips.
The indicator light (U.S. models :
CRUISE , Canadian models:•(') ) in the
instrument cluster illuminates when the system is on.
& WARNING
• To help keep the vehicle under control, do not use the cruise
control system when driving on winding or slippery roads (as
caused by heavy rain or loose gravel on the road surface), or in
heavy or varying traffic.
• Only use the cruise control when traffic, road and weather
conditions allow you to drive at a steady speed.
[ i] Tips
The cruise control cannot maintain a constant speed when driving
downhill. The vehicle will accelerate under its own weight. Down­
shift to a lower gear or use the brakes to slow down .•

You can also increase the vehicle speed by depressing the acceler­
ator pedal. The vehicle speed will increase as long as you keep the
accelerator pedal depressed. When you let up on the accelerator
pedal, the vehicle speed will automatically return the to previously
stored vehicle speed in the cruise control.
If the actual vehicle speed exceeds the stored vehicle speed in the
cruise control for longer than five minutes and by more than 6 mph
(10 km/h), the cruise control will automatically erase the stored
vehicle speed and you will have to reset the cruise control again.
Tapping the lever lightly @
By lightly tapping the lever@toward G) ~ fig. 138, you can
increase vehicle speed by approximately 1 mph (2 km/h).
By lightly tapping the lever @toward
