the Tec hnical Data
Q page 288.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
In vehicles without a coolant temperature in­
d icator , an indicator l ight . will turn on
when the coolant temperature is too h igh
Q page 20. Refer to Q Q) .
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tern- perature is h
igh. This is not a cause for con­
cern as long as th e . indicator light in the
display does not turn on.
Hot range
If the L EDs in the upper area of the disp lay
and the. indicator light in the instrument
cluster disp lay t urn on , the coo lant tempera ­
ture is too high
c::> page 20.
A WARNING
I-
- Always observe the warn ing in
c::> page 217, before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment.
You could burn yourse lf . Let the engine
coo l off f irst unti l yo u can no longe r see
or hea r steam or coolan t escap ing.
Q) Note
- In vehicles w ith a boost pressure indica­
to r*, this indicator replaces the tempe ra­
t ur e display. To promote a long engine
service life, avoiding h igh engine speeds,
full acceleration and he avy eng ine lo ads
during approximately the first 15 m i­
nutes when the engine is co ld is recom ­
mended. The amount of time until the
eng ine is warm depends on the outside
temperat ure. Check the engine oil tem­
perature* if necessary.
c::> page 32
- Add itiona l head lights and other compo­
nents in front of the air intake impairs
the cooling effect of t he coolant. This in­
creases the risk of the engine overheat­
ing during high outs ide temperatures
and heavy eng ine load.
- T he front spoiler also he lps to d istr ibute
cooling ai r correctly wh ile driving. If the
spoiler is damaged, the coo ling effect
w ill be imp aired and the risk of the en­
gine overhea ting will increase . See an au­
thorized Audi dealer or autho rized Audi
Service Facility for assistance . ...,

If the light doe s not turn off after starting
the engin e
or turns on while driving, this may
indicate there is a malfunction in the eng ine.
If the indicator turns on, the catalytic convert­
er may be damaged .
Drive
with reduc ed engine perfo rm ance
(avo id h igh speeds for extended periods of
time and/or fast accelerat ion) and have the
malfunction corrected. See an authorized Audi
dealer o r authorized Aud i Service Facility .
The indicator may turn on if the electron ic
speed limiter is faulty. For additional informa­
tion, refer to

for a complete roof rack system. Additiona l
attachments or carrier systems are needed
to transport luggage and sports equipment.
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. 57.
-We recommend that you keep the installa­
tion instructions for your roof rack system
together with your Owner's literature in the
vehicle .
When should the roof rack be remo 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 consump­
t ion, w ind no ise and to guard against theft .
A WARNING
-Use of an unapproved roof rack or incor­
rect mount ing of an approved roof rack
can cause the roof rack or the items at­
tached to it to fa ll off the roof onto the
road.
- Objects fall ing from the roof of a veh icle
can cause a c rash and persona l injury.
- Only mount the roof rack on the desig­
nated locations on the roof¢
fig. 57.
-The roof rack system must be installed
exactly according to the instructions pro­
vided.
- When driving w ith a roof rack system,
changes to the center of g ravity and wind
resistance can change the veh icle han­
dling and lead to a collision. A lways
adapt your driving and your speed to the
c u rrent conditions.
(D Note
- Your veh icle warranty does not cover any
damages to the veh icle caused by using
r oof racks or mo unting structures not
approved by Audi for your vehicle. The
same applies to damage resulting from i ncorrect roof rack installation.
S eat s an d sto rage 63
- Always check the roof rack mountings
and hardware before each trip and dur­
ing a trip to make s ure everyth ing is se ­
curely tightened. If necessary, ret ighten
the mountings and check the entire sys­
tem from time to time.
- After mount ing 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 unde r low bridges or in parki ng
garages for example. This cou ld cause
damage to the load and even the vehicle
itself .
- Make sure the open rear lid and the sun­
roo f* do not come in to contact with the
roo f rac k.
Loading the roof rack
Always distribute loads evenly. Make sure
anything on the roof rack is securely tied
down .
.,. Always dis tribute the loads on the roof rack
even ly .
.,. Always attach items to the roof rack securely
before you drive off .
T he maxim um permissible roof we ight is
1 6 5 lb (75 kg ). The roof weight is the total of
the weight of the roof rack, the attachments
and the cargo you are carrying. You must a lso
not exceed the maximum load weight for the
roof rack you are using.
When using a roof rack system which has a
lower load carrying capacity, you must not use
up the tota l maximum permissible load carry­
ing capacity specified above. Instead, you
should load the roof rack system only to the
max imum capacity specified by the manufac­
ture r of the roof rack system .
A WARNING
Weak, damaged or imprope r straps used
to secure items to the roof rack can fail
during ha rd braking o r in a coll is ion and
cause ser ious persona l injury .
.
•

64 Seats and storage
-Make sure the roof rack is installed exact­
ly as specified above
r::;, page 62.
- Always use suitable mounting straps for
securing items to the roof rack to help
prevent items from shifting or flying for­
ward.
- Items on the roof rack must always be
securely mounted.
- The use of a roof rack can negatively 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 gravity and overall handling. Always
drive slowly, 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
vehicle, the permissible axle weights and
the permissible total weight of your veh i­
cle
r::;, page 286, Weights.
@ For the sake of the environment
As a result of the increased wind resist­
ance created by a roof rack, your vehicle is
using fuel unnecessarily. So remove the
roof rack after using it .

212 Checking and Fill in g
- If you put any amount of incorrect fue l in
the fue l tank, do not start the engine un­
der any circumstances. Immediately con­
tact the nearest authorized Audi dealer
or authorized Audi Service Facility for as­
sistance. These fuels contain substances
that can severely damage the fuel sys­
tem and the engine if the engine is start­
ed.
- If the diesel fuel quality is poor, it may
be necessary to have the water drained
from the water sepa rator in the
f ue l fi l­
te r
more often than specified in the
maintenance schedu le . This can help re­
duce engine ma lfunctions

Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel fi ller flap.
If the power locking system should fail, you
can st ill open the flap manually- for detailed
instructions
seer:::.> page 214.
You can find the fuel tank capacity of your ve­
hicle in
Qpage 288.
The label on the inside of the fuel filler flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
c;,page 210.
Your veh icle fuel tank has an onboard refue l­
ling vapor recovery system . This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refuel your vehicle . In order to fill the tank
properly while protect ing the env ironment,
p lease follow t his refueling procedure careful­
ly.
.&_ WARNING
Under norma l operating conditions, neve r
carry additiona l fuel containers in your car .
Gas can isters and other containers used to
transport fue l can be dangerous. Such con­
tainers, full or empty, may leak and cou ld
cause a f ire in a collision. If you must transpo
rt fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe local and state laws regard­ ing the use, transportation and storage of
such fuel containers. Make certa in the con­
tainer meets industry standa rds (ANSI/
ASTM F8S2 -86).
(D Note
Neve r drive your veh icle until the fue l tank
i s completely empty. The irregular supply
of fue l can cause misfir ing. Gasoline cou ld
enter the exhaust system and damage the
catalytic converter.

~ Close fuel filler door until it latches.
Once the pump nozzle switches off, the fuel
tank is "full". Do not fill the tank more. Other­
wise the expansion space in the tank will be
filled.
The correct fuel type for your vehicle can be
found on a label located on the inside of the
fuel filler door. For additional information on
fuel, refer to ¢
page 210.
The fuel tank capacity of your vehicle is in the
Technical Data ¢ page 288.
To avoid fuel spilling or evaporating from the
fuel tank always close fuel filler cap properly
and completely. An improperly closed fuel fill­
er cap may also cause the MIL lamp ¢

to come on .
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, ex­
plosions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
- If you do not switch the engine off when
fueling and/or do not insert the fuel noz­
zle completely into the tank opening,
fuel can leak out or run over. Leaked fuel
can ignite and start a fire.
- Do not use the telephone while fueling.
The electromagnetic rays can cause
sparks, which can ignite fuel vapors and
start a fire .
- Do not sit in your vehicle while fueling. If
you must make an exception and enter
your vehicle again while fueling, close
the door and touch metal to discharge
static electricity before touching the fuel
nozzle. Static electricity can create
sparks, which can ignite vapors when fu­
eling.
Checking and Filling 213
- Do not smoke or have an open flame in
the area when fueling your vehicle or fill­
ing a fuel container because this increas­
es the risk of an explosion .
- For your safety, carrying fuel containers
in your vehicle is recommended. Wheth­
er full or empty, the container can leak
and cause a fire in the event of an acci­
dent.
- If you must make an exception and
transport a fuel container, note the fol­ lowing:
- Never fill the fuel container with fuel
while it is in or on the vehicle. Static
electricity is discharged when filling
which can cause the fuel vapors to ig­ nite and increases the risk of an explo­
sion.
- Always place a fuel container on the
ground before filling.
- Always hold the fuel nozzle completely
in the fuel container when filling .
- If the fuel container is made of metal,
the fuel nozzle must always be in con­
tact with the container when filling it
with fuel. This prevents static electrici­
ty from discharging.
- Never spill fuel in the vehicle or the
luggage compartment. Evaporated fuel
is explosive and increases the risk of
serious injury or death.
- Follow legal requirements when using,
storing and transporting fuel contain­
ers.
- Make sure the fuel container conforms
to industry standards (ANSI/ASTM
F8S2-86).
@ Note
- Remove spilled fuel from vehicle paint
immediately, because it can damage
paint.
- Never drive until the fuel tank is com­
pletely empty . The irregular supply of
fuel that results from that can cause the
engine to misfire. Uncombusted fuel will
enter the exhaust system and increase

the risk of damage to the catalytic con ­
verter .
- If the fuel tank runs comp letely empty in
a vehicle with a
die sel en gine , the igni­
tion must remain switched on for at l east 30 seconds after refueling before
starting the engine.
It may take longer
than usual for the engine to start, even up to a minute . Th is is because the air
must fi rst b leed out of the fuel system
when starting the eng ine.
@) For the s ake of the environment
- If the fuel nozzle is used correctly , it will
indicate that the tank is full the first
time it switches off automatically. Do
not t ry to add more fuel, because it can
spill over. Also , the expansion space in
the tank will fill, which can resu lt in fuel
spilling out when it becomes warm and po lluting the environment .
@ Tips
-If the engine is runn ing whi le fueling, va­
pors can escape or the fuel can spi ll over.
Because of this , the fuel nozz le switches
off before the tank is full.
- Do not fuel the vehicle when the ignition
is switched on. Otherwise, the fuel
gauge may not show the correct level af­
ter fueling the vehicle.
- Diesel vehicles are equipped with a diesel misfueling guard
ll. It allows the vehicle
to be fueled only with a diese l fuel pump
nozzle.
- A worn or damaged nozzle or a nozz le
that is too small may not be able to open
the d iesel m isfueling protector . If this is
the case, try t urni ng the nozzle before
i nserting it in the f uel filler neck, use a
different fuel p ump or see you r a uthor­
i zed Audi dealer or author ized repair fa­
cility for assistance .
- The m isf ueli ng guard does not open
when adding fuel from a fuel container .
ll Market-sp ec ifi c
You can bypass it by adding the diesel
fuel s lowly.
- The fuel fi ller door on your vehicle does
not lock when you lock the vehicle from
the inside.
