On Board Diagnostic
System (OBD)
Malfunction Indicator Lamp (MIL)
The Ma lfunction Indicator Lamp (MI L) ¢,ij in the
inst rument cluster is part of the On-Boa rd Diag­
nostic (OBD II) system .
T he wa rning/indicator light ill uminates when the
ignition is sw itched on and goes out after the en­
gine starts and the idle has stabilized. This indi­
cates that the MIL is working properly.
If the li ght do es not go out after the eng ine is
sta rted, or i lluminates while you are driving, a
malfunction may exist in the engine system. If
the lig ht illuminates, the catalytic converter
could be damaged.
Cont inue driving
with reduced power (avoiding
s ustained high speeds and/o r rapid accelera­
tions) and have the condit ion corrected. Contact
your authori zed Aud i dea ler .
If the light i llum inates, the elect ronic speed lim­
iter may also be malf unct ion ing. For more infor­
mation

An improperly closed fue l filler cap may also
ca use the MIL light to illuminate ¢

Cockpit overview
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.

Refrigerator
Introduction
Applies to: vehicles with refrigerator
Clean the refrigerator before the first use ~ table
on page 308.
You can only switch the refrigerator on, if :
- the temperature in the luggage compartment
is less than 131
° F (55 °(). If the refrigerator is
switched on , it will automatically switch off if
the temperature in the luggage compartment
exceeds 131
° F (55 °(). If the temperature
goes back below 131
° F (55 °(), the refrigera­
tor will automatically switch on again.
- The charge level of the vehicle battery is suffi.
cient. The refrigerator is automatically switch­
ed off if the electrical system voltage falls be­
low the spec ified minimum value. This prevents
the vehicle battery from discharging . The re­
frigerator automatically switches back on if th e
electrical system voltage increases again, for
example after starting the vehicle.
When the cooling function is working optimally,
the cooling function reaches 43° F
(+6 °C) and
the free zing function reaches 21 ° F
(-6 °C). The
cooling temperature in the refrigerator also de­
pends on the luggage compartment tempera­
ture. When the temperature in the luggage com­
partment is high, there may only be a limited
cooling effect.
.&, WARNING
-
To avoid any injury risks to the passengers
caused by the refrigerator, the following safe­
ty precautions must be followed:
Seats and storage
-The maximum load capacity for the freezer
is
5.5 lbs (2 .5 kg).
- Never overload the refrigerator. There is a
risk of injury in the event of a collision or
sudden braking.
- The refrigerator cover must always be
closed and locked while driving. The refrig­
erator contents could enter the vehicle inte­
rior during a collision or sudden braking ma­
neuver, which increases the risk of injury.
- Never store flammable fluids, gas contain­
ers and similar objects in the refrigerator
due to the risk of an explosion . This also ap­
plies to goods and products that can emit
volatile or flammable gases.
-At temperatures of 32° F
(0 °() and lower,
frozen liquid inside glass containers can
cause the containers to burst.
(D Note
- The ventilation openings for the refrigerator
are at the rear panel trim panel in the lug­
gage compartment and must not be cov­
ered.
- If the refrigerator is not functioning correct­
ly, turn it off to prevent any damage. Have it
checked by an authorized Audi dealer or au­
thorized Audi Service Facility.
