Trip computer
Introduction
Applies to vehicles: wit h trip computer
The trip computer gives you information on
current and average fuel mileage, average
speed, fuel range and driving time .
Fig. 9 Tri p comp uter d isp lay: Ave rage fuel mileage
The follow ing informat ion is continuously
evaluated by the trip computer and can be dis­
p layed sequentially in the instrument cluster
display:
Fuel range
The estimated cruising range in miles (km)
appears in the display. This tells you how far
your vehicle wi ll be able to t ravel on the cur ­
rent tank of fue l and with the same driving
style. The display changes in increments of
5 miles (10 km).
The cruising range is calculated based on the
fuel consumption for the last 18 miles
(30 km). If you drive conservatively, the cruis­
ing range will increase.
Average fuel mileage
The average fuel economy in MPG (l/100 km)
since you last cleared the memory appears in
this display. You can use this disp lay to adjust
your driving technique to achieve a desired mileage .
Current fuel mileage
The instantaneous fuel consumption in miles
per gallon (l/100 km) is shown in this display .
You can use this display to adjust your driving
technique to achieve a desired mileage. Fuel
consumption is recalcu lated at intervals
of 33 yards (30 meters). This disp lay switches
to gallons/hour (liters/hour) when the vehicle is not moving.
Average speed
The average speed in mph (km/h) s ince you
last reset the memory appears in the display.
Elapsed time
The length of time that you have been driving
s ince you last reset the memory appears in
th is disp lay.
Distance
The distance that has been covered since the
last t ime the memory was cleared appears in
the display.
(0 Tips
- Fuel consumptions (average and cur ­
rent), range and speed are displayed in
metric units on Canadian models.
- All stored values will be lost if the vehi­
cle battery is disconnected .
Memories
Applies to veh icles: w ith t rip co mputer
The trip computer is equipped with two fully
automatic memories as well as an efficiency

Single-trip memory (Trip computer 1)
The single -trip memory stores the trip infor­
mat ion from the time the ignition is turned on
until it is turned off. If the trip is continued
within 2 hours from the time the ignition was
turned off, the new data will be included in
the calculation of the current trip informa­
tion. If the trip is interrupted for
more than 2
hours the memory is reset automatically.
Total-trip memory (Trip computer 2)
Unlike the sing le-trip memory, the total-trip
memory is not reset automatically. This per­
mits you to evaluate your driving data for the
enti re pe riod between manual resets.

tery is disconnected.
On-Board Diagnostic
system (OBD)
Malfunction Indicator Lamp (MIL)
The Malfunction Indicator Lamp (MIL) ¢..ift in
the instrument cluster is part of the On-Board
Diagnostic (OBD II) system.
The warning/indicator light illuminates when
the ignition is switched on and goes out after
the engine starts and the idle has stabilized .
This indicates that the MIL is work ing proper­
l y.
Driver information display 29
If the light does not go out after the engine
is started, or illuminates while you are driv­
ing , a malfunction may exist in the engine sys ­
tem.
If the light illuminates, the catalytic con­
verter could be damaged.
Continue d rivin g
with reduced power (avoid­
ing su sta ined high speeds and/or rapid accel ­
erations) and have the cond ition corrected.
Contact your authorized Audi dealer.
If the light illuminates, the electronic speed
li miter may also be malfunct ioning. For more
information

On-Board Diagnostics monitors the compo­
nents of your emission contro l system . Each
monitored component in your engine system
has been assigned a code. In case of a mal­
function, the component will be identified
and the fault stored as a code in the control
module memo ry .
The MIL light may also illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem. If the light illumi nates afte r a refueling,
stop the vehicle and make sure the fuel filler
cap is properly closed

Roof rack
Description and mounting locations
Additional cargo can be carried with a roof
luggage rack .
Fig. 75 Seda n: Roof ra ck atta chmen t po ints
Fig. 76 allroa d: Roof ra ck atta chm ent po ints
~ Always read and follow the instructions pro­
vided by the roof rack manufacturer when
installing the roof rack system.
If luggage or cargo is to be carried on the roof, you must observe the following:
- Only use roof racks approved for your vehi ­
cle. These approved roof racks are the basis
for a complete roof rack system. Additional
attachmen ts or carrier systems are needed
to transport luggage a nd sports equ ipment .
We recommend using roof racks from the
Audi original accessories program.
- When installing the roof rack, make sure it
is only mounted on the designated locations
on the roof ¢
fig. 75 or¢ fig. 76 .
- We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner 's literature in the
veh icle .
Sea ts a nd s to rage 69
When sh ould th e ro of rac k be r emo ved ?
-Before going through an automatic car wash
(it is best to ask the car wash operator for
advice).
- When not in use, to reduce fuel cons ump­
tion, wind noise and to guard against theft.
A WARNING
=
- Use of an unapproved roof rack or incor-
rect mounting of an approved roof rack
can cause the roof rack or the items at­
tached to it to fall off the roof onto the road.
- Objects falling from the roof of a vehicle
can cause a crash and personal injury.
- Only mount the roof rack on the desig­
nated locations on the roof
i:> fig . 75.
- The roof rack system must be installed
exactly according to the instruct ions pro­
vided.
- When driving with a roof rack system,
changes to the center of gravity and wind
resistance can change the vehicle han ­
dling and lead to a collision . Always
adapt your driving and your speed to the
cur ren t conditions.
(D Note
- Your vehicle warranty does not cover any
damages to the veh icle caused by using
roof racks or mounting structures not
approved by Aud i for your veh icle. The
same app lies to damage resulting from
incorrect roof rack installation.
- Always check the roof rack mountings
and hardware before each trip and d ur­
ing a trip to make sure everything is se­
curely tightened. If necessary, retighten
the mountings and check the entire sys­
tem from time to time.
- After mounting a roof rack system, or
when you transport objects on the roof
of your vehicle, the height of the veh icle
is naturally increased. Be careful when
dr iving under low bridges or in parking
garages for example . This cou ld cause
111>

70 Seat s a nd s tor ag e
damage to the load and even the vehicle
itse lf.
- Make sure that the open rear lid and the
sunroof do not come into contact with
objects on the roof.
Loading the roof rack
Always distribute loads evenly. J\llake sure
anything on the roof rock is securely tied
down.
.. Always dist ribute the loads on the roof rack
evenly .
.. Always attach items to the roof rack securely
before you drive off.
The maximum permissible roof weight is
2 00 lb (90 kg ). The roof weight is the total of
the we ight of the roof rack, the attachments
and the cargo you are carry ing. You must also
not exceed the maximum load weight for the
roof rack you are using .
When us ing a roof rack system which has a
lower load carry ing capac ity , you must not use
up the total max imum perm issible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the maximum capacity spec ified by the manufac­
turer of the roof rack system.
A WARNING
Weak, damaged or improper straps used
to secure items to the roof rack can fail
during hard braking or in a co llision and
cause serious personal injury.
- Make sure the roo f rack is insta lled exact­
ly as specified above
,=;,page 69.
- Always use suitable mounting straps for
sec uring items to the roof rack to help
prevent items from shifting or flying for­
ward.
- Items on the roof rack must always be
sec urely mo unted.
- T he use of a roof rack can negative ly af ­
fect the way a vehicle handles . Cargo
that is large, heavy, bulky, long or flat
will have a greater negative influence on
.
the vehicle's aerodynamics, center of
grav ity and overall handling. Always
drive s lowly, avoid sudden braking and
maneuvers when transporting cargo on
the roof of your vehicle.
- Never exceed the maximum permissible
load carrying capacity of the roof of your
veh icle, the permissible axle weights and
the permissible total weight of you r vehi­
cle~
page 280, Weights.
(D Note
Make sure that the opened rear lid does
not come in contact with the cargo on the
r oof.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, you r vehicle is
us ing fuel unnecessarily . So remove the
r oof rack after using it.
