.&_ WARNING
Improper use of steer ing whee l adjustment
and improper seating position can cause ser i­
ous pe rsonal injury.
- Adjust the steering wheel column on ly when
the vehicle is not mov ing to prevent loss of
vehicle control.
- Adjust the driver's seat o r steering wheel so
that there is a minimum of 10 in (25 cm)
be tween your chest and t he s teering wheel
~ page 101, fig. 101 . If yo u cannot main ­
tain this minimum distance, the airbag sys­
tem cannot protect you properly.
- If physica l limitations prevent you from sit ­
t ing 10 in (25 cm)
or more from the steer ­
ing wheel, check with your authorized Audi
dealer to see if adaptive equipment is avail­
able .
- If the steering wheel is aligned with your
face, the supplemental driver's airbag can-
60
not provide as much protect ion in an acci­
dent. Always make sure that the steer ing
wheel is aligned with your chest.
- Always hold the steering wheel with your
hands at the 9 o'clock and 3 o'clock posi­
tions to reduce the risk of personal in jury if
the driver's airbag deploys .
- Never hold the steering wheel at the 12
o'clock position or with your hands inside
the steering wheel rim or on t he steering
wheel hub . Holding the steering wheel the
wrong way can cause serious in juries to the
h an ds, arm s and head if the drive r's airbag
deploys.

Driving
Under certain circumstances, (such as driving in
the mountains or towing a trailer), it may be use­
ful to switch temporarily to the manual shift pro­ gram in order to manually adapt the gear to the
driving conditions
c::> page 71.
On inclines, activate the parking brake first and
then move the selector lever to the P position
c::> page 65. This prevents the locking mechanism
from being loaded too heavily and will make it
easier to move the selector lever out of the P po ­
sition .
_& WARNING
-The vehicle can also roll when the engine is
stopped.
- Unintended vehicle movement can cause se­
rious injury.
- Never leave your vehicle with the engine
running while in gear. If you must leave
your vehicle when the engine is running, ac­
tivate the parking brake and move the selec­
tor lever to P.
- 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 when the en­
gine is running and the selector lever is in D/
Sor R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running .
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptron ic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. Constant braking causes the
brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
70
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicator lamp . illuminates
and a driver message appears
c::> page 72
when the clutch is overloaded.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
c::> page 159. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
(D Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when th@ engine
is stopped while the selector lever is in the
N position will damage the automatic trans ­
mission, because it is not lubricated under
those circumstances
c::> page 211, Towing
with a tow truck.
- The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop-and-go traffic. If the.
indicator light turns on, stop the vehicle at
the next opportunity and let the transmis­
sion cool down
c::> page 72.
Hill descent control
The hill descent control system assists the driver
when driving down hills.
Hill descent control is activated when the selec­
tor lever is in the D or S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach- ieved at the time of braking, within physical and ..,.

Fig. 79 Perm itted ball pos itio n of th e t rail er hitch
Trailer towing weights
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible trailer weight is
2,200 lbs (1,000 kg) . The maximum permissible
unbraked trailer weight is 1,650 lbs (750 kg) .
These specifications apply when driving on roads having an incline of less than 12%.
Permissible tongue load
For best vehicle handling under these changed
conditions, adjust the trailer load so that the
tongue load is at the maximum allowable or
slightly lower. You can get an approximation of
the tongue load with a bathroom scale or you can
measure the load at a trucking company or
weighing station.
With a
factory-installed or an aftermarket trailer
hitch, the maximum permissible load on the ball
hitch may not exceed 220 lbs (100 kg) .
It is rec­
ommended to use the maximum permissible
load.
Trailer load distribution Be sure the load in the trailer is held securely in
place to prevent it from shifting forward, back­
ward or sideways.
Never allow a passenger to ride in a trailer ¢.&.
in Driving instructions on page 76 .
Ball mount
The trailer hitch may only be used with suitable ball mount and ball¢
fig. 79. Installation of the
hitch ball must be carried out in accordance with
the manufacturer's instructions .
Trailer towing
Engine cooling system
Towing a trailer makes the engine work harder. It
is important that the cooling system's perform­
ance is up to the additional load. Make sure that
the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the tire pressure listed under "Full
load" on the tire pressure label
¢page 181. In­
flate trailer tires to trailer and tire manufactur­
ers' specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be sure trailer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners. When you install safety chains, make
sure they will not drag on the road when you are
driving.
The chains should cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
· Driving instructions
Driving with a trailer always requires extra care
ond consideration.
Weight distribution
Towing a loaded trailer with an empty car results
in a highly unstable distribution of weight. If this
cannot be avoided, drive at very low speeds only
to avoid the risk of losing steering control.
A "balanced " rig is easier to operate and control.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while
keeping the trailer as light as possible under the
circumstances. Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observing tongue load require-
ments and vehicle loading considerations. .,.

Checking and Filling
Gasoline
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your veh icle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rat ing of 91 AKI (95 RON). For more
in fo rmation on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas.co m).
The recommended gasoline octa ne rating for
your eng ine can a lso be fo und o n a label located
on the inside of the fue l filler flap. Th is rat ing
m ay be s pec ified as A KI or RON.
Your ve hicle may also be operated us ing unlead­
ed regular gasoline with a minimum octane rat­ in g of 87 AKI/9 1 RO N. However, using 8 7 AKI/9 1
RO N octa ne f uel w ill slightly reduce engi ne pe r­
f o rm an ce.
Use unleaded gasoline only. Unleaded gasoline
i s available throug hout t he USA, Canada, and in
m ost European co untr ies . We recom mend that
you do not t ake your veh icle t o area s or co untries
w here un leaded gaso line m ay not be av a ila ble.
For mo re informa tion on re fueling your veh icle,
see
r=;, page 15 6 .
Octane rating
Octane rati ng indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . The refore, buy ing
the co rrect grade of gasoline is ve ry important to
h e lp p revent poss ible e ngine damage and a loss
of eng ine pe rforma nce.
Gasoline mos t commonly used in the United
S tates a nd C anada has the following octane ra t­
in gs that ca n usually be fo und o n the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 - 90 A KI
Checking and Filling
Explanation of the abb reviations:
A KI=
A nti K nock Index= ( R+ M )/2 = (R ON+M ON )/
2
RON = Resea rch Octa ne Number
MON= Motor Octane Number.
(D Note
- Do not use any f uel w ith octane ratings low ­
er than 87 A KI or 9 1 RO N ot herwise e xpe n­
sive engine damage w ill occur.
- Do
not use lea ded gasoline . T he use of lead ­
ed gasoline will severe ly damage you r vehi­
cle's catalyt ic converter and its ability to
cont rol exhaust emissions .
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unlead ed gasoli ne b le nded with al­
c o hol o r MTB E (commonly referre d to as oxyge n­
ates) if the blende d m ix tu re meets the fo llow ing
c rit e ri a:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knoc k index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
- An ti- kno ck index mus t be 87 A KI or hi gher.
- Blend must not co nta in mo re than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or h igher.
- Blend must contain not mo re than 15% MTBE .
Seasonally adjusted gasoline
Many gasoline grades a re blended to perform es­
pecially well for w in ter o r su mmer dr iv ing . D ur ­
i ng seasonal cha nge-ove r, we sugges t that yo u
fill up a t busy gas st at io ns w here the seasonal
adjus tme nt is mo re li kely to be made in t ime. ..,.

Closing the fuel cap
""Screw the tank cap on to the right on the filler
neck until it cannot turn any farther.
""Then press on the left side of the tank door un­
ti l it latches .
Checking and Filling
Once the pump nozzle switches off, the fuel tank
is "full". Do not fill the tank more . Otherwise 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,
see
¢ page 155.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section¢ page 216.
To avo id fuel spilling or evaporat ing from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp¢
page 17 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
-
-If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
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
veh icle aga in while fueling, close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:
157

Checking and Filling
-Never f ill the fuel container with fuel
while it is in or on the vehicle. Stat ic elec­
tricity is d ischarged when filling wh ich can
cause the f uel vapors to ignite and in­
creases the r isk of an explos ion .
- Always p lace a fuel container on the
ground before fi lling .
- Always hold the fuel nozzle comp letely in
the fuel container when fi lling .
- If the fue l conta iner is made of metal, the
fue l nozzle must always be in contact wit h
the conta iner w hen filling it w ith fue l. Th is
prevents static electr ic ity from discharg­
ing.
- Never sp ill fuel in the veh icle or the lug ­
gage compartment . Evaporated fue l is ex­
plosive and increases the risk of se rio us i n­
jury o r death.
- Follow legal requireme nts when usi ng,
s t o ring and tran spo rting fuel cont ainers.
- Ma ke sure the fue l conta iner confo rms to
i ndu stry st anda rds (A NSI/ ASTM F852-86).
0 Note
- Remove spilled fuel from vehicle paint im­
mediately, because it can damage paint.
- Never drive until the fuel tank is completely
empty . The ir regular supp ly of fuel that re­
su lts from that ca n cause engine m isfires .

Catalytic converter
It is very important that your emission control
system (catalytic converter) is functioning prop­
erly to ensure that your vehicle is running in an
environmentally sound manner .
.,. Always use lead -free gasoline ¢ page 155, Fuel
supply.
.,. Never r un the tank down all the way to empty .
.,. Never put too much motor oi l in your engine
¢ page 164 .
.,. Never try to push- or tow-start your vehicle .
The catalytic conve rter is an efficient "clean-up"
device built into the exhaust system of the veh i-
cle. The catalyt ic converter burns many of the

Checking and Filling
on even if the ignition is switched off, which
increases the risk of personal injury.
- Never open the cap on the coolant expan­
sion tank when the engine is warm. The
cooling system is under pressure.
- To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a
large cloth when opening.
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If tests need to be performed with the en­ gine running, there is additional danger due
to moving components (such as the ribbed
belt, alternator and radiator fan) and from
the high-voltage ignition system .
- Do not under any circumstances activate the throttle inadvertently (for example, by hand
from the engine compartment) if the vehi­
cle is stationary but the engine is running
and a gear is engaged. Otherwise, the vehi­
cle will start to move immediately and this
could result in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke .
- Never work near open flames.
- Always have a working fire extinguisher
nearby
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable - Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­
tor lever in the P (park) position first .
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents . Tie back long hair before beginning
160
work and do not wear clothing that can
hang down into the engine .
- Limit your exposure to exhaust and chemi­
cals to as short a time as possible
c:> ,& .
-All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility .
