This indicator can help conserve fuel.
Fig. 12 Display: Gearshift indicator
In order to become familiar with the gearshift in­
d ictor, at firs t just drive the way you are used to.
If the current gear - and the driving situation -is
not the best one for conserving fuel, then the in­
d icator will display the recommended gear. The
display shows the current gear and the gear that
is recommended
c>fig. 12.
-Upshifting The display will light up to the right
of the gear currently selected if it is recom­
mending a higher gear.
-Downshifting: The display will light up to the
left of the gear current ly selected if it is recom­
mending a lower gear.
Sometimes the indicator will recommend skip­
ping a gear (3
> 5).

If there is no gearshift recommendation, then
just drive in the appropriate gear for conserving
fuel.
(D Note
This indicator can help you conserve fuel. This
indicator is not meant to show you which gear
you should a lways be in in all driving situa­
tions. Somet imes, in situations such as pass­
i ng, driving through mountains or when tow­
i ng a tra iler, there won't be any gearshift rec­
ommendat ion.

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 Diag­
nostic (OBD II) system .
The warning/indicator light illuminates when the
ignition is switched 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 light does not go out after the engine is
started, or illuminates while you are driving, a malfunction may exist in the engine system.
If
the light illuminates, the catalytic converter
could be damaged.
Continue driving
with reduced power (avoiding
sustained high speeds and/or rapid accelera­
tions) and have the condition corrected. Contact
your authorized Audi dealer.
If the light illuminates, the electronic speed lim­iter may also be malfunctioning. For more infor­
mation
¢ page 29, Electronic speed limiter.
An improperly closed fuel filler cap may also
cause the MIL light to illuminate ¢

Seats and storage
Fig. 75 allroad : Roof rack attachme nt points
"'Always read and follow the instructions provid­
ed by the roof rack manufacturer when instal­
ling 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 vehicle .
These approved roof racks are the basis for a
complete roof rack system . Add it ional attach­
ments or carrier systems are needed to trans­
port luggage and sports equipment. We recom­
mend using roof racks from the Audi original
accessories program.
- When insta lling the roof rack, make sure it is
only mounted on the designated locations on
the roof
r::!> fig. 74 or r::!> fig. 75.
- We recommend that you keep the installation
instructions for your roof rack system together
with your Owner's literature in the vehicle .
When should the roof rack be removed?
-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 consumption,
wind noise and to guard against theft .
_&. WARNING
- Use of an unapproved roof rack or incorrect
mounting of an approved roof rack can
cause the roof rack or the items attached 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 designated
locations on the roof
r::!> fig. 7 4.
- The roof rack system must be install ed ex-
actly according to the instructions provided. ..,.

Seat s and sto rage
-When driving with a roo f rack system,
changes to the center of gravity and wind
resistance can change the vehicle handling
and lead to a collision . A lways adapt your
dr iv ing and your speed to the current condi·
t ions .
{U) Note
- Your vehicle warranty does not cover any
damages to the vehicle caused by using roof
racks or mounting structures not approved
by Aud i for your vehicle . The same applies to
damage resulting from incorrect roof rack i nst allation .
- Always check the roof rack mount ings and
hardware befo re each trip and dur ing a tr ip
to make s ure everyt hing is securely tight­
ened.
If necessary, ret ighten the mo unt ings
and check the entire system from time to
time.
- After mounting a roo f rack system, or when
you transport objects on the roof of your ve­
hicle, the height of the veh icle is naturally
i nc reased. Be careful when driving under
l ow bridges or in parking garages for exam­
ple . This could cause damage to the load
and even the vehicle itself.
- Make sure that the open rear lid and the
su nroof do not come into contact with ob·
j ects on the roof .
Loading the roof rack
Always distribute loads evenly. Make sure any ­
thing on the roof rack is securely tied down .
"'Always distribute the loads on the roof rack
evenly .
"' Always attach items to the roof rack securely
before you dr ive off .
The max imum perm issible roo f weight is
2 00 lb
( 90 kg ).
The roof weight is the total of the
weight of the roof rack, the attachme nts and the
cargo you are carrying . You must also not exceed
the maximum load weight fo r the roof rack yo u
a re using.
68
When using a roof rack system wh ich has a lower
l oad carrying capacity, you must not use up the
total max imum permissib le load carry ing capac i­
ty specified above. Instead, you should load the
roof rack sys tem only to the maximum capacity
specified by the manufacturer of the roof rack
system.
A WARNING
Weak, damaged or improper straps used to
secure items to the roof rack can fail du ring
hard brak ing or in a collision and cause seri­
ous persona l injury .
- Ma ke sure the roof rack is i nstalled exactly
as spe cified above
~ page 67 .
-Always use suitable mo unt ing straps fo r se·
cur ing items to the roof ra ck to help preven t
items from sh ifting or flying forward .
- Items on the roof rack must a lways be se·
cure ly mounte d.
- The use of a roof rack can negative ly affect
the way a vehicle handles . Cargo that is
large, heavy, b ulk y, long or flat w ill have a
greater negative influence on the vehicle's
aerodynamics, center of grav ity and overa ll
handling . Always drive slowly, avoid sudden
braking and maneuvers when transporting
cargo on the roof of your vehicle .
- Never exceed the maximum permissib le
load carry ing capacity of the roof of your ve­
hicle, the perm iss ible axle weights and the
perm iss ible total we ight of your vehicle
~ page 255, Weights.
(D Note
Make sure that the opened rear lid does not
come in contact with the cargo on the roof .
@ For the sake of the environment
As a result of the increased wind resistance
created by a roof rack, your vehicle is using
fuel unnecessarily . So remove the roof rack
after using it .

Climate control system
Description
The climate control system warms, cools and
adds humidity to the air in the veh icle inter ior. It
is the most effective when the windows and sun ­
roof are closed. If there is a build-up of heat in­
side the vehicle, ventilation can help to speed up
the cooling process.
I n all heating mode functions except
defrost, the
b lower only switches to a higher speed once the
engine coolant has reached a certain tempera­
ture .
Condensat ion from the cooling system can drip
and form a puddle of water under the veh icle.
This is normal and does not mean there is a leak.
P ollutant filt er
The pol lutant filte r removes pollutants such as
dust and pollen from the a ir.
The air pollutants filter must be changed at the intervals specif ied in your Warranty
& Mainte­
nance booklet, so that the a ir cond it ione r can
properly work.
If you drive your vehicle in an area with high air pollut ion, the filter may need to be changed
more frequently than specified i n your Aud i War­
ranty
& Maintenance booklet. If in doubt, ask
your author ized Audi Service Advisor for advice.
Ke y cod ed setting s
The climate control settings are automatically
stored and assigned to the remote control key
that is in use .
.8, WARNING
Reduced visib ility is dangerous and can ca use
accidents.
- For safe dr iv ing it is very impo rtan t that all
windows be free of ice, snow and condensa­
t ion .
76
- Complete ly familiarize yourself with the
proper use and function of the heating and
ventilation system and espec ially how to de­
fog and defrost the wi ndows .
- Never use the windshield wiper/washer sys­
tem in freezing weather until you have
warmed the windshield first, using the heat­ ing and vent ilation system. The washer solu­
tion may freeze on the windshield and re­
duce visibi lity.
(D Note
- If you suspect that the air conditioner has
been damaged, sw itch the system off to
avoid further damage and have it inspected
by a q ualified dealership.
- Repa irs to the Aud i air cond itioner requ ire
special techn ica l know ledge and spec ial
tools. Contact an a uthorized Audi dealer fo r
assistance.
@ For the sake of the environment
By reduc ing the amo unt of fuel you use, you
also reduce the amount of pollutants emitted
into the a ir.
(D Tips
- Keep t he a ir intake slots (in front of the
windshield) free from ice, snow and debr is
in orde r to maintain the prope r funct ion of
the climate control system .
- The energy management sys tem may sw itch
the seat heating* o r rea r window defroster
off temporarily. These systems are available
again as soon as the energy balance has
been restored.
- 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.
