I f the
air quality sensor in the air conditioning sys tem detects
exhaust fumes in the outside air, the control unit wil l either pass the
incoming a ir through the pol lution filter, or automatically switch on
the air recirculation .
The air conditioning syste m wi ll aut omatically swi tch o n the ai r
recirculation if it senses that the outside air is very po lluted. At the
same time, it wil l not al low any outside air to ente r the vehic le until
the a ir quality has improved .
T he air recircula tion operates for a maximum of
12 minutes. If the
w indows s tart to fog up whi le the air rec ircula tion is on, press[@!.
Under certain operating conditions (for example, if 1@1 or

Using the climate controls economically
Using the climate controls pru dently can help save fuel.
When you use the air conditioner, engine power is reduced
and fuel consump tion increases. To save fuel, yo u sh ould
use the air conditio ner on ly when necessary. Also please
n ote th e follow ing points:
- If you want to save fuel, activate ECON.
- If you are goi ng to drive with the power top down, use
ECON.

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. _,.

Do not stop the engine immediately after hard or extended driving.
Keep the engine running for approximately two minutes to prevent
excessive heat build-up. •

If you should drive off with the parking brake still set, a warning tone
will sound and the following will appear in the instrument cluster to
remind you to release the parking brake:
Parking brake set
The parking brake warning comes on only after you have driven for longer than 3 seconds and faster than 5 mph (5 km/h).
The parking brake warning light Brake (Canada:
{(j))) illuminates
when the parking brake is set and you switch on the ignition .
& WARNING
Always release the parking brake completely. A partially engaged
brake will overheat the rear brakes, reduce their effectiveness and
cause excessive wear. This could lead to brake failure and an acci­
dent.
0 Note
Only after the vehicle has come to complete stop, should you firmly
set the parking brake and either move the gearshift lever into 1st.
gear (manual transmission) or move the selector lever into P (Auto ­
matic transmission). •
Parking
To prevent a parked vehicle from rolling away, there are a
few things you should do.
When you park your vehicle, do the following:
- Stop the vehicle using the brake pedal.
- Set the parking brake firmly.
- Move the selector lever into the

R -Reverse
The transmission will automatically select the lowest gear ratio
when you shift into reverse.
Select
R only when the vehicle is at a full stop and the engine is
running at idle speed~
& in "Driving the automat ic transmission"
on
page 126 .
Before you move the selector lever to R, press both the button in the
handle of the selector lever
and the brake pedal at the same time.
When the ignition is on, the backup lights illuminate when the selector lever is moved into
R.
N -Neutral
The transmission is in neutral in this position. Shift to this position
for standing with the brakes applied~
page 128.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the footbrake before and while moving the
lever out of
N.
D -Normal position for driving forward
Position Dis for normal city and highway driving. It ranges from zero
to top speed and all six gears shift automatica lly, depending on
engine load, driving speed and automatically selected shift
programs. The gear engaged is shown in the right of the display
~ page 127, fig. 140.
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and whi le moving the
lever to
D out of N .
In certain circumstances it may be advantageous to temporarily
switch to the manual shift program to manua lly se lect gear ratios to
match specific driving conditions~
page 130.
S -Sport position
Select this position for sportier performance. In this position, the
t ransmission will not upshift as soon, allowing the vehic le to use the increased power available at higher engine speeds
to achieve live­
lier accelera tion .
When the vehicle is stationary or at speeds below 3 mph (5 km/h),
you must always apply the foot brake before and while moving the lever to
S out of N.
& WARNING
Read and follow all WARNINGS ~ & in "Driving the automatic
transmission" on
page 126.
(D Note
Coasting downhil l with the transmission in N and the engine not
running w ill result in damage to the automatic transmission and
possibly the catalytic converter. •

A time delay e lement prevents the selecto r lever from locking when
it is moved through the
N position (going from R to Dl. The locking
element will lock the selector lever if the lever is left in N (Neutral)

Int erlock button
The lock button on the selector lever prevents the lever from be ing
accidentally shifted into certain positions . Pressing this bu tton

Controls and equip ­
ment
App lies to veh icles: with 6-speed automatic transmission
Kick-down
T he kick-down feature allows the vehicle to generate
ma ximum acceler ati on.
When you press the accelerator peda l beyond the resistance point
that is reached at ful l throttle, the transmission will select a lower
gear ratio based o n vehicle speed and engine RPM. The engine RP M
wil l be control led to produce maximum vehicle acceleration as long
as you continue to press the acce lerato r pedal beyond this resis­
tance point.
& WARNING
Be care ful when using the ki ck-down feature on slippery road s.
Rapid acceleration may cause the vehicle to skid . •
App lies to vehicles: with 6-speed automatic transm iss ion
Dynamic shift program (DSP)
T he aut omatic transmission is electronically controlle d.
The transmission is se lf adapting and will auto matically se lect the
best sh ift program suited to the driving conditions and driving style.
The transmission wil l select one of the
e conomy programs when
you drive at a steady speed or a gradually changing speed without
heavy acceleration. This achieves optimum fuel efficiency, with early
upshifting and delayed downshifting.
The transmiss ion w ill automatically select the
s porty shift programs
when you drive at higher speeds, or with heavy acceleration and
frequently changing speeds . Upshifts are delayed to make full use
of engine power. Downshifting takes place at higher engine speeds
than in the economy p rog rams . _,.
