On-Board Diagnostics
Fig. 19 Location of Data Link Connector (DLC)
On-Board Diagnostics monitors the components
of your emission control system. Each monitored
component in your engine system has been as­
signed a code . In case of a malfunction, the com­
ponent will be identified and the fault stored as a
code in the control module memory.
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery system.
If the light illuminates after a refueling, stop the
vehicle and make sure the fuel filler cap is prop­
erly closed
¢ page 269.
In order to make an accurate diagnosis, the stor­
ed data can only be displayed using special diag­
nostic equipment (generic scan tool for OBD).
In order to connect the special diagnostic equip­ ment, push the plug into the Data Link Connector
(DLC). The DLC is located to the right of the hood
release
¢ fig. 19.
Your authorized Audi dealer or a qualified service
station can interpret the code and perform the
necessary repair.
A WARNING
Do not use the diagnostic connector for per­
sonal use. Incorrect usage can cause malfunc­
tions, which can increase the risk of a colli­
sion!
Electronic speed limiter
-
Your vehicle may be factory equipped with tires
that are rated for a maximum speed of 130 mph (210 km/h). This is less than the maximum speed
of your vehicle . To reduce the risk of sudden tire
26
failure and loss of control if the vehicle is operat­
ed at excessive speeds, your vehicle also has an
electronic speed limiter. The electronic speed
limiter prevents your vehicle from going faster
than the tire speed rating. For more information
¢ page 290.
If the engine control unit receives faulty vehicle
road speed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
ass istance.
58
Your vehicle's top speed is electronically limited
to 155 mph (250 km/h).
If the engine control unit receives faulty vehicle
roadspeed signals, the Malfunction Indicator
Lamp (MIL)
¢'4 will illuminate. If this occurs,
contact the nearest authorized Audi dealer for
assistance.
A WARNING
Always observe the posted speed limits and
adjust your speed to suit prevailing road, traf­
fic and weather conditions. Never drive your vehicle faster than the maximum speed rating
of the ti res installed.

climate control
Description
The climate con trol system warms, coo ls and re ­
moves humidity from the air in the vehicle inte ri­
or. It is the most effective when the w indows and
sunroof* are closed. If there is a bu ild-up of heat
i n side the veh icle, ven tilat ion can he lp to speed
up the cooling process .
In a ll heating mode functions, except for defrost,
the blower on ly switches to a higher speed once
the eng ine coolant has reached a sufficient tem­
perature.
Pollutant filt er
The po llutant filter removes pollutants such as
d ust and pollen from the air.
Key recognition
The clima te control settings are automatically
s tored and assig ned to th e remo te contro l key
that is in use.
& WARNING

Driving
Economical and environmentally-friendly
driving
The amount of fue l consumption, the environ ­
mental impact and the wear to the engine,
brak es and tir es d epends mostly on your driving
style. W ith an anticipatory and economic driv ing
style, fuel consumption can be reduced by ap­ proximately 10-15% . The following tips will help
you conserve the environment and your money at the same time .
Anticip atory d riving
A vehicle uses the most fuel when acce lerating.
When you drive with ant ic ipat ion , you do not
need to brake as often and so you accelerate less .
When possible, let your ve hicle coast w ith a
g ear
e ngag ed ,
for example , when you notice that the
next traffic light is red. This produ ces a n eng ine
b raking effect, which helps to protect the brakes
and tires and reduces the emissions and fuel con­
sumption to zero (f uel shut-off during decelera ­
tion).
Shift effici ently
An effective way to save f uel is to upshift earlie r.
Staying in a gear too long uses fue l unnecessari ­
ly. Press down on the accelerator pedal slowly
and avoid "k ick-down".
Avoid full acceleration
You sho uld rare ly t ravel at the maximum vehicle
speed. High speeds cause a disp roportiona tely
h igh increase in fuel consumption, emissions and
traffic noise . Slower driving saves fuel.
Reduce idling time
The Start-Stop system * helps to reduce the id ling
time automatically . In vehicles witho ut the Start­
S top sys tem* , it is efficient to switch the eng ine
off when stopped at ra ilroad cross ings a nd long
red lights . Stopping t he engine for 30 -40 sec ­
onds already saves more fuel than the amount of
extra fuel needed to restart the eng ine .
It takes a very long time in idle to wa rm the en­
gine up to operating temperature . Wea r and
emissions are especially high in the warm -up
phase. Therefore, yo u should begin driving im-
74
mediate ly after s tarting the engine . Avoid high
RPMs whi le doing this.
Have maintenance performed regularly
By having maintenance pe rformed regu la rly on
you r vehicle, you can help to reduce fuel con ­
s u mption before you even sta rt to drive. The
maintenance condition of your vehicle not on ly
affects traffic safety and long-term value but al ­
so impacts fuel consumption. A poorly main­
ta ined engine can lead to fuel consumption that
i s 10% higher than normal.
Avo id short trip s
The engine and exha ust cleaning system must
reach their optima l operating temperature to ef­
fect ive ly reduce consumpt ion and emissions.
A cold engine uses a d isproportionately high
amount of fue l. The engine reaches operating
temperat ure and cons umption no rmalizes on ly
after approximate ly four kilometers.
Check the tire pre ssure
To save fuel, ma ke sure the tires are always in­
flated to t he corre ct pressure
¢ page 291 . The
fuel consumption can increase by 5% if the pres­
sure is only 0 .5 bar too low. Due to the increased
roll ing resistance, low tire pressures w ill also
lead to greater tire wear and will affect driving
behavior.
D rive with summer tires when possib le because
th is can increase fue l economy by up to 10%.
Eliminate unnecessary we ight
Since eve ry po und of extra weight increases f uel
consump tion, it pays to remove any unnecessa ry
weight .
A roof rac k increases the w ind resis tan ce on the
vehicle and shou ld be removed when it is not
needed . You will save approximately 12% o f you r
fuel when at speeds from 62-75 mph (100-120 km/h) .
Save energy
The eng ine d rives the genera tor , which gene rates
e lectric ity; the fuel consumpt ion also increases
with t he demand for e lec tricity . T he refore, switch ..,_

Automatic transmission
Introduction
The automat ic transmission is cont rolled e lec­
tron ica lly . Power is transferred using a torque
converter.
The transm ission shifts up or down a utomat ica lly
depending on w hich drive program is sele cted.
When a
moderate driving style is used , the
transmission selects the most economical d riving
mode. The t ransm iss ion upsh ifts at a lowe r RPM
a nd downshifts at a highe r RPM to imp rove fuel
effi ciency .
The transm ission sw itches to a spo rty mode after
a ki ck-down or when the drive r uses a
sporty
driving style
c haracterized by quick accelerator
pedal movements, heavy acce leration , freq uent
changes in speed and traveling at the maximum
speed.
If desired , the dr iver can also select the gears
manually (tiptronic mode)
