Instruments and indicator lights
(+S °C), a snowflake symbol appears in front of
the temperature display.
If your vehicle is stationary or if you are driving at
very low speeds, the temperature displayed may
be slightly higher than the actual temperature
outside due to the heat radiating from the en­
gine.
A WARNING
Do not assume the roads are free of ice based
on the outside temperature display . Be aware
that there may be ice on roads even when the
outside temperature is around 41 °F (+S
0
()
and that ice can increase the risk of accidents .
@ Tips
You can change the measurement units, for
example for temperature or speed, in the
MMI.
Fuel level
The display @ q page 10, fig. 3 only works when
the ignition is switched on. When the display has reached the reserve mark, the bottom LED will
turn red and the
tj] indicator light turns on
q page 24. Th e bottom LED blinks red when
the fuel level is very low.
The on-board computer shows the range based
on the fuel level~
page 29, On-board comput­
er display.
For the tank capacity in your vehicle , refer to the
Technical Data
qpoge 303.
(D Note
Never drive until the tank is completely emp­
ty . The irregular supply of fuel that results
from that can cause engine misfires . Uncom­
busted fuel will then enter the exhaust sys­
tem. This can cause overheating and damage
to the catalytic converter.
Coolant temperature indicator
In vehicles without a coolant temperature indica­
t or, an indicator light . will turn on when the
12
coolant temperature is too high q page 20. Re­
fer to
q 0 .
The coolant temperature indicator @ q page 10,
fig. 3
only works when the ignition is switched
on. To prevent engine damage, please observe
the following notes about the temperature rang­
es .
Cold range
If only the LEDs at the bottom of the gauge turn
on, the engine has not reached operating tem­
perature yet. Avoid high engine speeds, full ac­
ce lerating and heavy engine loads.
Normal range
The engine has reached its operating tempera­
ture once the LEDs up to the center of the gauge
turn on under normal driving conditions. The
LEDs higher up may turn on if the engine is under
heavy load or the outside temperature is high.
T his is no cause for concern as long as the. in­
dicator light in the instrument cluster does not
turn on.
Hot range
If the LEDs in the upper area of the display and
the . indicator light in the instrument cluster
display turn on, the coolant temperature is too
high
q page 20 .
A WARNING
-Never open the hood if you can see or hear
steam or coolant escaping from the engine
compartment . This increases the risk of
burns . Wait until you no longer see or hear
steam or coolant escaping.
- The engine compartment in any vehicle can
be a dangerous area. Stop the engine and
allow it to cool before working in the engine
compartment. Always follow the informa­
tion found in¢
page 236, Working in the
engine comportment.

-In vehicles with a boost pressure indicator*,
this indicator replaces the temperature dis­
play. To promote a long engine service life,

You must drive your vehicle about 3,000 miles
(5 ,000 kilomet ers) before you can prop erly as ­
sess o il consumption .
This a lso applies to fuel consump tion and engine
output .
(D Note
-Have your vehicle mainta ined properly and
i n accor dance wi th the service re commenda­
tions in yo ur War ranty
& Maintenance book ­
l et. Lack of proper maintenance as well as
i mproper use of the vehicle will impair the
function of the emission control system and
could lead to damage .
- Do not alter or remove any component of
the Em ission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such as
heat shie lds, sw itches, ignition wires,
valves, which a re designed to protect yo ur
vehicle's Em ission Control System and other
i mportant vehicle components.
Fewer short trips
Fuel consumption will always be relatively high
on short trips.
• Try to avoid driving short dist ances with a cold
engi ne .
T he eng ine and catalytic converter have to reach
their optimal
operating tempe rature to reduce
fuel consump tion and noxious emissions effec­
tively .
Just after starting, a cold engine in a mid-si ze car
only achieves a fuel economy of 6-8 miles per
ga llon (30-40 l/100 km). A fter about a half a
m ile , fuel economy cl imbs to 12 mpg (20 l/
100 km) . After about
2.5 miles (4 km), the en­
g ine is a t its prope r operating temperature and
fuel economy has reache d a normal level. So you
c a n see t hat you s hou ld avoid sho rt t rips whenev­
er possib le .
The
outside temperature is also cr itical in th is re­
g ar d. Yo ur car c onsumes mo re fuel in the w in ter
than in the s umme r.

Automat ic t ra nsm iss io n
-Never select R or P while driving, because
this increases the risk of an accident.
- Power is still transmitted to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping" , you must
keep your foot on the brake in all selector
lever positions (except P) when the engine is
running. Otherwise, this increases the r isk
of an accident.
- Do not inadvertently press the accelerator
pedal when the veh icle is stopped if a gear is
engaged. Otherwise the vehicle will start to
move immediately, even if the parking brake
is set. This cou ld result in a crash.
- Do not press the accelerator pedal when
changing the selector lever position wh ile
the vehicle is stationary and the engine is running .
- Never leave yo ur vehicle with the engine
running whi le in gear. If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- To decrease the risk of an accident, these­
lector lever must be in the P position and
the parking brake must be set before open­ ing the hood and working on a running en­
gine . Always read and follow the applicable
warnings
q page 236, Working in the en­
gine compartment.
(D Note
Never let the veh icle roll downhill with engine
off and the selector lever in the
N position,
because this could damage the automatic
transmission and catalytic converter .

Gasoline fuel
Gasoline grade
A pp lies to veh icles: w ith gaso li ne engine
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven w ith
unleaded ga soli ne.
Aud i recommends using TOP TIER Detergent Gas­
oline. Additional information on TOP TIER Deter­
gent Gaso line can be found on the offic ial web­
site (www .toptiergas.com) .
The individua l gasoline grades are differentiated
by
octane ratings . This value is given with (R +M)/
2 equating to AK I or in RON.
The fo llow ing headings match the co rrespon ding
sticker in the fue l fi ller door .

Checking and Filling
Refueling
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
still open the flap manually· for deta iled instruc­
tions see~
page 232 .
You can find the fuel tank capacity of your vehicle
in
c::;, page 303 .
The label on the inside of the fuel filler flap tells
you the correct fuel for your vehicle . For more in­
formation about fuel specifications, see
c::;, page 228 .
Your vehicle fuel tank has an onboard refuelling
vapor recovery system . This feature helps to pre·
vent fuel vapors from escap ing from the tank and
polluting the environment while you refuel your
veh icle. In order to fill the tank properly while
protecting the environment, please fo llow this
refueling procedure carefully .
.&, WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
canisters and other containers used to trans­
port fuel can be dangerous . Such containers,
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 blower, etc.,
be very careful a nd always observe local and
state laws regard ing the use, t ransportation
and storage of such fue l containers. Make cer·
tain the container meets industry standards (ANSI/ASTM F852 · 86).
(D Note
Never drive yo ur vehicle unt il the fuel tank is
completely empty. The ir regula r supply of
fue l can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.

Checking and Filling
@ Tips
Fue l can age and may lead to prob lems when
starting. Audi recommends replacing the fuel
in your vehicle within six months.
@ Tips
- If the engi ne is running while fueling, va­
pors can escape or the fuel can spill over.
Because of th is, the fuel no zzle 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 t he correct level after fueling the
vehicle .
- Diesel veh icles are equ ipped with a diesel
misfueling guard
1>. It allows the vehicle to
be f ueled on ly w ith a diesel fuel pump noz­
zle .
- A wo rn o r damaged nozzle or a nozzle that
i s too smal l may not be ab le to open the
diesel misfueling protector . If this is the
case, try t urning the nozzle before inserting
i t in the f uel fille r neck, u se a d ifferent fue l
pump or see an aut horized Audi dea ler or
a uthorized Audi Service Facility fo r assis­
tance .
- The misf ueling guard does not open when
adding fue l from a fue l conta iner . You can
bypass it by adding the diesel fuel slow ly.
- The fuel filler door on your ve hicle does not
l ock when you lock the vehicle from the in­

Catalytic converter
Applies to vehicles: with gasol ine engine
It is very important tha t your emi ssion control
sys tem (ca talytic conv erter) is functioning prop­
erly to ensure that your vehicle is running in an
env ironmentally sound manner .
.,. Always use lead-free gasoline ~ page 228, Gas­
oline grade .
.,. Never run the tank down all the way to empty . ..,.

0 > co ,...., ~ Never put too much motor oil in your engine
¢ page 242, Adding engine oil ~ Never try to push-or tow-start your vehicle.
The cata lytic converter is an efficient "clean -up"
device bui lt into the exhaust system of the vehi­
cle. The catalytic converter burns many of the
pollutants in the exhaust gas before they are re­
leased into the atmosphere.
The exclusive use of unleaded fue l is critica lly im­
portant for the life of the catalytic converter and
proper functioning of the engine.
A WARNING
The temperature of the exhaust system is
high, both when driving and after stopping
the engine.
- Never touch the exhaust tail pipes once they
have become hot. This could result i n burns .
- Do not park or operate the vehicle in areas
where the hot exhaust system may come in
contact with dry grass, brush, fuel spill or
other material which can cause a fire .
-Do not apply additional undercoating or
rustproofing o n or near the exhaust mani­
fold, exhaust pipes, catalytic converte r o r
heat s hields. During dr iving, t he substance
used for under coati ng could ove rheat and
c ause a fire.
(D Note
- Be aware that just one tank filling with
leaded fue l wi ll al ready ser iously degrade
the pe rformance of the ca talytic converter.
- Do not ex ceed the correct eng ine o il level
~page 242.
- Do not d rive until the fuel tank becomes
complete ly empty. The engine co uld m is­
fire. Unburned fuel could also get in to the
exhaust system and this co uld cause t he
cata lytic converter to overheat .
- Do no t sw itch off t he igni tion while t he vehi­
cle is moving.
- Do no t continue to operate your vehicle un­
der these cond it ions, as othe rwise fue l can
reach the catalytic converter. This cou ld re ­
su lt in overheating of the converter, req uir­
i ng its replacement.
Ch eck ing and Filling
-To ass ure eff icient operat ion of the Emis ­
sion Contro l System:
- Have yo ur vehicle maintained p roperly and
i n accordance with the serv ice recommen­
dat ions in yo ur War ranty
& Ma intenance
booklet.
- L ack of proper ma intenance as well as im­
p roper use of the ve hicle will impa ir the
f u nction of t he emission control system
a nd could lead to damage.
~ For the sake of the environment
Eve n when the Em iss ion Control System is op­
era ting properly, t he exhaus t gas can have a
su lf ur -li ke exhaus t gas sme ll under some op­
erating s tates . This depends on the sul fur
content of the fuel being used. Using a differ­
ent brand of fuel may help, or fi lling the tank
with lead-free super grade gasoline.
Diesel particulate filter
Appl ies to vehicles: wit h diesel eng ine
The diese l particu late filter filte rs nearly all of
the soot part icles out of the exhaust. The filter
cleans itself automatically under norma l driving
condit ions. If the filter cannot clean itself (for ex­
amp le, because yo u are o nly dr iving short distan ­
ces), the filte r becomes clogged with soot and

A WARNING
-Do not park your veh icle over flammab le
materia ls such as grass or leaves because
the high temperature of the diesel particu ­
late filte r cou ld start a fi re.

Changing the engine oil
We recommend that have your oil changed by an
authorized Audi dealer or a qualified service sta ­
tion .
Before you check anything in the engine compart­
ment,
always read and heed all WARNINGS
c::> page 236.
The engine o il must be changed according to the
intervals specified in your Warranty
& Mainte­
nance book let. This is very important because the
lubricating properties of oil diminish gradua lly
during norma l vehicle use.
Under some circumstances the engine oil shou ld
be changed more frequent ly. Change oil more of­
ten if you drive mostly short distances, operate
the vehicle in dusty areas or under predominantly
stop-and-go traff ic conditions, or have your vehi­
cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time. This is normal and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposal, along
with the special tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi dealer or
a qualified service stat ion.
If you choose to change your oil yourself, please
note the following important information:
A WARNING ,-~
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
