200 Driving and the environment
Vehicles use the most fuel when they are ac­
celerati ng. If you anticipate what is going to
happen next, you will need to brake less and,
thus, accelerate less. let the vehicle coast
whenever poss ible -for example when you see
that the next traffic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well be low your car's max imum
speed.
Accelerating gently reduces fuel consump­
tion, engine wear, and does not disturb the
environment. F ue l consumption, exhaust emissions and en ­
gine noise increase disproportionately at hig h
speeds . If you drive at approximately three
quarters of top speed, fue l consumption will
be reduced by one half. Never dr ive faster
tha n the posted speed limit and weather con­
d itions permit.
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.. Sh ut the engine off when you are not dr iving
the vehicle.
.. Do not warm up the vehicle by letting the
engine run at idle.
It is efficient to switc h off the engine when
stopped at railroad crossings and long red
lights. Turning the engine off for just 30-40
seconds saves mo re fuel than is burned by
start ing the eng in e again.
It takes a long time for the engine to warm up
fu lly when it is running at idle. However, wear
and nox ious em issions are especially high
when the engine is warming up. So you should
d rive away as soon as you sta rt the eng ine and
avoid ru nning a t high RPM wh ile the engine is
still warming up .
(D Note
Do not leave engine i dling unattended af­
ter start ing. If wa rning lights sho uld come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat , w hich could result in over­
hea ting o r othe r damage to the veh icle or
othe r property.
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel.
.. Have your ve hicle serviced at regu lar inter-
vals.
Having your veh icle regu larly serviced by an
authorized Aud i dealer helps to ensure that it
runs properly and econom ica lly. The cond it io n
of your veh icle not on ly affects its safety and
ability to ho ld its va lue, i t also affects
fuel
c onsumption .
Check your oil each t ime you fill your tank.
The amount of oi l used is re lated to engine
l oad and speed.
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certain
mileage has been driven .
You m ust drive your ve hicle abou t 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion .
T his also ap plies to fue l consumption and en ­
gine o utp ut.
(D Note
- Have your veh icle ma inta in ed properly
and i n acco rdance with the service rec­
ommendations in you r W arranty
& Main­
t enance boo klet. l ack of proper ma inte ­
nance as well as im proper use of the ve­
hicle will impair the function of the
em iss ion cont ro l system and cou ld lead
to damage.

202 Trailer towing
Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a tra iler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
T railer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, always fo llow the operating
and drivi ng i nstr uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and mu st be
mounted secure ly on the ve hicle's chassis at a
technically sound location . Use only a trailer
h itch with a removab le ball mount. A lways
check with the tr ailer hitch manu fac tur er to
make sure tha t you are using t he cor rect
hitch.
Do not us e a bumper hitch .
The hitch must be installed in such a way t hat
it does not interfe re with t he impact-absorb­
ing bumper syst em . No mod ifications should
be made to the vehi cle exhaust and brake sys ­
tems . From time to time, check th at a ll hit ch
mo unt ing bo lts remain secure ly fastened.
When you are not towing a trail er, remove the
tra iler hitch ba ll mount. This prevents the
hi tch from causing d amage sho uld your ve hi­
cle be str uck from be hind
¢ A .
Trailer brakes
If you r tra ile r is eq uipped w ith a braking sys­
tem, check to be su re that it conforms to a ll
r egulat ions . T
he trailer hyd raulic brake system mus t not be
direct ly connected to the vehicle's hydraulic
brake system .
Safety chains
Always use s afety chains be tween your ve hicle
and t he tra ile r.
Trailer lights
Tra ile r li ghts must meet all regulations. Be
su re to c hec k w ith your Audi dea le r fo r cor rect
wiring, swi tches and relays.
Mirrors
If you are unable to see the traffic behind you
u sing the regular o utside m irrors, then you
must insta ll ext ended mirro rs . It is important
t h at you
always have clea r vis io n to the rea r.
,8. WARNING
-
Afte r removing t he trailer hit ch, d o no t
s tore it in yo ur vehicle . In case of sudden
br aking, t he h itch cou ld fly forward an d in­
j ur e you or yo ur passengers .
Operating instructions
Maximum traile r weight
A trai le r fo r you r vehicle is limited to a typi cal
class 1 or class 2 trai le r.
Trailer load distribution
B e sure the load in the t ra ile r is held secure ly
i n p lace to p reven t it from shift ing forw ard,
backw ard or sideways.
Never allow a passenger to ride in a trailer
¢ A in Driving instru ctions on page 203.
Engine cooling system
Towing a trailer makes the engine work hard­
er . It is impo rtant that the cooling system 's
performance is up to the additional load .
Make su re that the coo ling system has enough
fl uid .
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to t he cold tire pressure listed under
ll>

M N
0 > co ,...., \!) 1.1'1
M 1.1'1 ,....,
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer t ires to tra iler and t ire manufac­
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the chains to per­
mit turning corners. When you install safety
chains, make su re they wi ll not drag on the
road when you are driving.
The chains should cross under the tra ile r
tongue to prevent it from dropping in case of
separation from the hitch.
Driving instructions
Driving with a trailer always requires extra
care and consideration.
To obtain the best poss ible handling of vehicle
and traile r, p lease note the following:
~ Do not tow a loaded tra iler when your car it­
self is not loaded.
~ Be especia lly careful when passing other
vehicles.
~ Observe speed limits .
~ Do not drive at the maximum permissible
speed.
~ Always apply brakes early.
~ Monitor the temperature gauge.
Weight distribution
Towing a loaded trai ler with an empty car re­
sults 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 con ­
trol. This means that the tow vehicle should be loaded to the extent poss ible and permiss i­
ble, wh ile keeping the trailer as light as poss i­
ble under the circumstances . Whenever possi-
Trailer towing 203
ble, transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle load ing
considerations.
Speed
T he higher the speed, the mo re difficult it be­
comes for the driver to control the rig. Do not
drive at the maximum permissib le speed. Re­
duce your speed even more if load, weather or
wind conditions are unfavorable -particularly
when going downhill.
Reduce veh icle speed
immediately if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trai lers are lower than for
regular vehicles .
Always apply brakes early. When driving
downhi ll, shift into a lower gear to use the en ­
gine braking effect to s low the vehicle. Use of
the brakes alone can cause them to overheat
and fail.
Coolant temperature
The coolant temperatu re gauge <=> page 12
must be observed carefu lly. The coolant tem ­
perature can increase if you drive on long in­
clines in a low gear at high engine speeds. Re­
duce your speed immediately if the LEDs in
the top part of the display turn on.
For more information about indicator lights,
refer to .<=>
page 20.
A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident. Never let anyone ride in your car
who is not properly wearing the restraints
provided by Audi.

Checking and Filling
Gasoline
Fuel supply
Applies to vehicles: with gasoline engine
Using the right fuel helps keep the environ­
ment clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your vehicle is un­
leaded premium
grade gasoline . Audi recom­
mends using TOP TIER Detergent Gasoline
with a minimum octane rating of91 AKI (95
RON) . For more information on TOP TIER De ­
tergent Gasol ine, please go to the official
website (www .toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label locat­
ed on the ins ide of the fuel filler flap. This rat­
ing may be specified as AKI or RON .
Your vehicle may also be operated using un­
leaded regular gasoline with a minimum oc ­
tane rating of 87 AKI/91 RON . However, using
87 AKI/91 RON octane fuel w ill slightly re­
duce engine performance.
Use unleaded gasoline only. Unleaded gaso­
line is available throughout the USA, Canada,
and in most European countries. We recom­
mend that you do not take your vehicle to
areas or countries where unleaded gasoline
may not be available.
For more information on refueling your vehi­
cle, see
~ page 212.
Octane rating
Octane rating ind icates a gasoline's ability to
res ist engine damaging "knock" caused by
premature ign ition and detonation . Therefore,
buying the correct grade of gasoline is very
important to help prevent possible engine
damage and a loss of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane
r atings that can usually be found on the filler
pump : - Premium Grade: 91
-96 AKI
- Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON
+MON)/2
RON= Research Octane Number
MON = Motor Octane Number .
@ Note
-Do not use any fuel w ith octane ratings
lower than 87 AKI or 91 RON otherwise
expensive engine damage w ill occur.
- Do
not use leaded gasoline. The use of
leaded gasoline will severely damage
your vehicle's catalytic converter and its
ability to control exhaust emissions.
Blended gasoline
Applies to vehicles: with gasoline engine
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded gasoline blended with
alcohol or MTBE (commonly referred to as
oxygenates) if the blended mixture meets the
following criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
-Anti-knock index must be 87 AK I or higher.
- Blend must contain no more than 3% meth-
anol.
- Blend must contain more than 2% co-sol-
vents.
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
-Anti-knock index must be 87 AKI or higher.
- Blend must not contain more than 15%
ethanol.
Blend of gasoline and MTBE
-Anti-knoc k index must be 87 AK I or higher.
- Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline

Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
Q;) Note
- Methanol fuels which do not meet these requirements may cause corrosion and
damage to plastic and rubber compo­ nents in the fuel system .
- Do not use fuels that fail to meet the
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specificat ions, ask your service station or
i ts fuel supp lier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and
M
N fuel systems clean, they are not equally effec-o
iii tive. ,...., \!) ..,.,

Checking and Filling 211
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
App lies to vehicles : wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2 . The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel
higher than 5
% such as B11, B2O or B1OO are
strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni­
tion by the user.
If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­
gine's starting and running. Depending on the
season, gas stations provide ULSD No . 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was de­
signed solely for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
contain substances that will severely
damage the fuel system and the engine.
Such damage will not be covered by your
New Vehicle Limited Warranty.

- 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

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

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

Selective catalytic reduction
General information
Applies to vehicles: with diesel e ngine
In vehicles with se lective cata lytic reduction, a
urea solut ion (Ad Blue) is injected into the ex­
haust system before a nitrogen oxide catalytic
converter to reduce nitrogen -emissions .
Ad Blue is the marketing name for Diese l Ex­
ha ust Fluid (DEF) .
The AdBlue is carried in a separa te tank in t he
vehicle . The AdBl ue usage accounts for ap­
proximately 0.5% to 1.2% of the diese l fuel
that is used .
When a message abo ut refil ling the Ad Blue
appears in the inst rume nt cl uste r dis play, you
must refi ll the Ad B lue yourse lf or have it refil­
