ant
level is too low ¢ page 17.
.&_ WARNING
- Always observe the warning in
¢ page 187, Engine compartment be­
fore opening the engine hood and check­
ing the engine coo lant level.
- Never open the engine hood if you see or
hear steam, or if you see engine coolant
dr ipping from the eng ine compartment.
You could burn yourself . Let the engine
cool off first so that you cannot hear or
see any steam or engine coolant .
0 Note
-Mounting additional l ights or accesso ries
i n front of the a ir inlets reduces the cool­
i ng effect of the rad iator. At h igh outside
temperatures or high eng ine load, the
engine could overheat.
- The front spo ile r has been designed to
properly distrib ute the cooling air when
the veh icle is moving.
If the spoiler is
damaged, this cou ld reduce the cooling
effect and the engine could then over­
heat. Ask your authorized Audi dea ler for
assistance.
Fuel gauge
The fuel gauge works only when the ignition is
on.
When the needle reaches the red area, the
warning light in the instrument cluster will il­
lum inate <=>

have approximately
1.8 gallons (7 liters) of
fuel left in the tank .
Time to re fu el!
The total tank capacity of your vehicle is listed
in¢
page 257, Data.
(D Note
Never run the tank completely dry! An ir­
regular supply of fuel can cause eng ine
m isfiring and fuel could enter into the ex­
haust system. The catalyt ic converte r
could then overheat and be damaged.

A WARNING
- Never rely exclusively on the outside
temperature display to determine if a
road surface is icy or not . Keep in mind
that road surfaces, especially bridges
and overpasses, could be ice covered and
slippery even at an outside temperature
above 41 °F (+S °C).
- Always remember, even if the "snow­
f lake" symbo l (ice warning) does not ap­
pear in the display, black ice could be on
the road.
- Always reduce your speed and drive with
special care in cold weather conditions
when the chance of encountering icy
road surfaces increases.
(D Tips
-If the vehicle is stationary, or if you are
driving at a very low speed, the tempera­
ture shown in the display might be
slightly h igher than the actual outside .,,.

On-Board Diagnostic
system (OBD)
On-Board Diagnostics
Fig. 9 Locat ion of Data Link Connector (DLC)
On-Boa rd Diagnostics monitors the compo­
nents of your em iss ion control system. Each
controlled component in your engine system
has been assigned a code . In case of a mal ­
function, the component wi ll be identified
and the fault stored as a code in the control
module memory.
The MIL lamp may a lso illuminate if there is a
leak in the on-board fuel vapor recovery sys­
tem. If the light illuminates after a refuelling,
pull off the road and stop the vehicle, then
check that the fuel filler cap is properly closed
c:> page 192.
In order to make an accurate diagnosis, the
stored data can only be displayed using spe ­
cial diagnostic equipment (generic scan tool
for 080) .
In order to connect the special diagnostic
equipment, push the plug into the Data Link
Connector (DLC). The DLC is located to the
right of the engine hood release lever
c:> fig. 9.
Your authorized Audi dealer or a qualified service station can interpret the code and per ­
form the necessary repair.

~/o Malfunction Indicator Lamp
(MIL)
The Malfunction Indicator Lamp (M IL) Ill
(USA models);II (Canada models) in the in­
strument 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 engine starts and the idle has stabilized.
This indicates that the MIL is work ing proper­
ly.
If the light does not go out after the engine
is started, or illuminates whi le you are driv­
ing, a ma lfunction may ex ist in the engine sys­
tem. If the light illuminates, the catalytic con­
verter could be damaged.
Continue driving
with reduced power (avoid­
ing sustained high speeds and/or rapid accel­
erations) and have the condition corrected.
Contact your author ized Audi dealer.
If the lig ht ill uminates, the e lectronic speed
limiter may also be malfunctioning. For more
information c:::> page 25, Electronic speed
limiter .
An improperly closed fuel filler cap may also
cause the MIL light to illuminate
c:::> page 192.
Electronic speed limiter
Your veh icle may be factory equ ipped with
tires that are rated for a maximum speed of
130 mph (210 km/h) . Thi s is less than the
maxim um speed of your vehicle. To reduce the
risk of sudden tire failure and loss of control if
the vehicle is operated at excessive speeds,
your vehicle also has an electronic speed limit­
er . The electronic speed limiter prevents your
veh icle from going faster than the tire speed
rating. For more informat ion
c:::> page 224,
Speed rating (letter code).
If the engine control unit receives fau lty vehi ­
cle roadspeed signals, the Malfunction Indica­
tor Light (MIL)
¢..ijj will illuminate. If this oc-

curs, contact the nearest authorized Audi
dealer for assistance.
A WARNING -
A lways observe the posted speed lim its
and adjust your speed to suit prevailing
road, traffic and weather conditions. Never
drive your vehicle faster than the maxi­
mum speed rating of the tires installed.
Trip computer

110 Driving Safely
&_ WARNING
Always make sure that the doors, all win­dows, the power roof* and the read lid are
securely closed and locked to reduce the
risk of injury when the vehicle is not being
used.
-After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get out. Being trapped in a vehicle can
lead to serious personal injury.
- Never let children play in or around the
vehicle.
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be properly restrained in one of
the vehicle's seating positions.
(D Tips
- The tire pressure must correspond to the
load -see the tire pressure sticker on the
fuel filler door.
- The tire pressure must correspond to the
load. The tire pressure is shown on the
tire pressure label. On USA vehicles, the
tire pressure label is located on the driv­
er's side B-pillar. On Canada vehicles, the
tire pressure label is located either on
the driver's side B-pillar or inside the fuel
filler flap. The tire pressure label lists
the recommended cold tire inflation pressures for the vehicle at its maximum
capacity weight and the tires that were
on your vehicle at the time it was manu­
factured. For recommended tire pres­
sures for normal load conditions, please
see chapter ¢
page 216.

Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the tie-downs to secure your cargo prop­
erly
¢ page 109, Loading the luggage com ­
partment .
In a collision, the laws of physics mean that
even smaller items that are loose in the vehi­
cle will become heavy missiles that can cause
serious injury. Items in the vehicle possess en­
ergy which vary with vehicle speed and the
weight of the item. Vehicle speed is the most
significant factor.
For example, in a frontal collision at a speed
of 30 mph (48 km/h), the forces acting on a 10-lb (4.5 kg) object are about 20 times the
normal weight of the item . This means that
the weight of the item would suddenly be
about 200 lbs. (90 kg). You can imagine the
injuries that a 200 lbs. (90 kg) item flying
freely through the passenger compartment
could cause in a collision like this.
&_ WARNING ~
Weak, damaged or improper straps used
to secure items to tie-downs can fail dur­
ing hard braking or in a collision and cause
serious personal injury.
-Always use suitable mounting straps and
properly secure items to the tie-downs in
the luggage compartment to help pre­
vent items from shifting or flying for­ ward as dangerous missiles.
- When the rear seat backrest is folded
down, always use suitable mounting
straps and properly secure items to the
tie-downs in the luggage compartment
to help prevent items from flying for­
ward as dangerous missiles into the pas­
senger compartment .
- Never attach a child safety seat tether
strap to a tie-down.

Winter operation
At temperatures below 20° F (-7° C), Diesel
fuel No.
2 loses its fluidity due to wax separa­
tion, which may clog the fuel filter or tank fil­
ter and keep the engine from running .
To help the filter from being clogged by wax,
the fuel filter in your vehicle is automatically
preheated. Preheating the fuel filter makes
operation of your vehicle possible with Diesel
fuel No . 2 down to -10° F (-24° C).
If you expect temperatures below
5° F
(-15° C)
ask your fuel dealer whether their
Diese l fuel No.
2 is sufficiently winterized for
the prevailing and expected temperatures.
If not winterized or insufficiently winterized
d iesel fue l has already thickened to the extent
that the engine will not start, warm the vehi­
cle up by leaving it in a heated garage.
It is normal that the engine noise leve l (die­
seling) is louder during the warm-up period in
winter.
It is also norma l when whitish-blue
smoke comes out of the tailpipe after start ing
and during warm-up . The amount of smoke
depends on the outs ide temperature.
Do not let your diesel engine idle unnecessari­
ly after a cold start. Driving off slowly will
shorten the warm-up period .
A WARNING
-Never use "starting assist fluids." They
may be potent ially explosive or cause a
"run-away" engine condition. This could
result in serious engine damage and per­
sonal injury.
- Never use fuel line anti-freeze offered for
gasoline engines .
0 Note
- Your diesel engine has been specifically
designed to operate only on Ultra Low
Sulfur Diesel fuel. Therefore, never use
home heating oil or regular gasol ine. Th e
properties of these fuels may cause seri­
ous damage to the fuel injection system
and to the engine. Using these fuels can
-
Fuel supply and filling your fuel tank 191
cause expensive engine repai rs and will
also adversely affect your New Vehicle
Limited Warranty.
- If diesel fuel should get on any rubber
hose, it must be wiped off immediately.
Then wash the contaminated hose por­
tion with soap and warm water. Do not
allow diesel fuel to remain on connecting
hoses. They may develop leaks and cause
ser ious damage.
Fuel tank
Fuel filler neck
The fuel filler neck is located on the right rear
side panel behind the fuel filler flap.
If the power locking system should fail, you
can still open the flap manually -for detailed
instructions see
¢ page 193.
You can find the fuel tank capacity of your ve­
hicle in
Technical Data ¢page 257 .
The labe l on the inside of the fuel fi ller flap
tells you the correct fuel for your vehicle. For
more information about fuel specifications,
see
¢ page 189.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you refue l your vehicle. In order to fi ll the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A WARNING
Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the
