Driving and th e en vironm ent
Regular maintenance
A badly tuned engine unnecessarily wastes a lot
of fuel.
.,. Have your vehicle serviced at regular intervals.
By having your vehicle regu larly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and econom ically . The condition of
your veh icle not only affects its safety and ability
to hold its value, it also affects
fu el consump­
tion .
C he ck your oil e ach t ime you fill you r ta nk .
The amount of oil used is re lated to engine load
and speed.
It is normal for the oil consumpt ion of a new en­
g ine to reach its lowest val ue afte r a certa in mile­
age has been driven .
You must d rive you r vehicle about 3 ,000 miles
(5,000 k ilome ters) before you can p roperly as ­
sess o il cons umption .
This a lso applies to fuel consumption and engine
outpu t.
(D Note
- Have your vehicle maintained properly and
in accordance with the service recommenda­
tions in you r Warranty
& Maintenance book ­
l et . La ck of p roper main tenance as well as
i mproper use of the vehicle will impa ir the
f u nct ion of the emission control system and
could lead to damage.
- Do not al ter or remove any component of
the Emission Control System unless ap­ proved by the manufacturer.
- Do not a lter or remove any device, such as
heat shie lds, switches, ignition wires,
valves, which are designed to protect your
vehicle's Emission 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 distances with a cold
eng ine .
T he eng ine and catalytic converter have to reac h
their opt imal
operating temper atu re to reduce
fuel consumpt ion and noxious emiss ions effec­
tively .
Just after start ing, a cold engine in a mid-size car
on ly achieves a fuel economy of 6-8 miles per
gallon (30-40 l/100 km) . After about a half a
mile, fuel economy climbs to 12 mpg (20 l/100
km) . After about
2 .5 m iles (4 km), the engine is
at its proper operating temperatu re and fuel
economy has reached a no rma l level. So you can
see that you should avoid sho rt tr ips wheneve r
possible .
The
out sid e temperatur e is also cr it ica l in th is re­
gard. Your car cons umes more fue l in the winter
than in the summer.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passenger
transportation .
If you plan to tow a trailer, please remember that
the additional load will affect durability, econo­
my and performance.
Trailer towing not only places more stress on the
vehicle, it also calls for more concentration from
the driver.
For this reason, always follow the operating and
driving instructions provided and use common
sense.
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suitable
for your vehicle and trailer and must be mounted
securely on the vehicle's chassis at a technically
sound
location . Use only a trailer hitch with a re­
movable ball mount . Always check with the trail­
er hitch manufacturer to make sure that you are
using the correct hitch.
Do not use a bumper hitch.
The hitch must be installed in such a way that it
does not interfere with the impact -absorbing
bumper system . No modifications should be
made to the vehicle exhaust and brake systems .
From time to time, check that all hitch mounting
bo lts remain securely fastened.
When you are not towing a trailer,
remove the
tra iler hitch ball mount . This prevents the hitch
from causing damage shou ld your vehicle be
struck from beh ind ¢
,&. .
Trailer brakes
If your trailer is equipped with a braking system,
gi check to be sure that it conforms to all regula-......
~ tions . N ...... 0

LL 00
Trailer towing
The trailer hydraulic brake system must not be
directly connected to the vehicle's hydraulic
brake system ¢.&. .
Safety chains
Always use safety chains between your vehicle
and the trailer.
Trailer lights
T ra iler lights must meet all regulations . Be sure
to check w ith your author ized Audi dealer for cor­
rect wiring, switches, and relays.
Mirrors
If you are unable to see the traffic behind you us­
ing the regular outside mirrors, then you
must in­
stall extended mirrors. It is important that you
always have clear vision to the rear.
,8. WARNING
-If a tra iler has electr ical brakes please note
that these bra kes are not activated by the
factory-fitted control unit -risk of accident!
- After removing the trailer hitch, do not
store it in your vehicle. In case of sudden
braking, the hitch could fly forward and in­
jure you or your passengers.
Operating instructions
Maximum trailer weight
A trailer for your vehicle is limited to a typical
class 1 or class 2 trailer.
Trailer load distribution
Be sure the load in the trailer is held sec ure ly 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 180.
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 cool ing system has enough fluid. .,..

Trailer towing
Tire pr essure
When tow ing a tra iler, inflate the tires of yo ur
veh icle to the tire pressure listed under " Fu ll
load" on the label ¢
page 217. Inflate trai ler
tires to trai ler and tire manufacturers' specifica­
tions.
Lights
The headlight settings should be chec ked with
the trailer attached before driving off . Check to
make sure both vehicle and trailer lights are
working properly.
Safety chains
Be s ure t railer safety chains are properly connect­
ed from the trailer to the hitch on the vehicle .
L eave enough slack in the chains to permit turn ­
ing corners. When you install safety chains, make
sure they wi ll not drag on the road when you are
driving.
The chains shou ld 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
and consideration .
Weight distribution
Towing a loaded trailer with an empty car res ults
in a high ly unstable distribution of weight . If this
cannot be avo ided, drive at very low speeds on ly
to avoid the risk of losing steering control.
A "balanced" rig is easie r to operate and cont rol.
This means that the tow vehicle should be loaded
to the extent possible and permissible, while keeping the trai ler as light as possib le under the
circumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow vehicle while observ ing tongue load requ ire­
ments and vehicle loading considerat ions .
Spe ed
The higher the speed, the more difficult it be­
comes for the driver to contro l the rig. Do not
drive at the maximum permiss ible speed. Reduce
your speed even more if load, weather or w ind
180
conditions are unfavorab le -particularly when
going downhi ll.
Reduce vehicle speed
immediate ly if the trailer
shows the slightest sign of sway ing.
Do not try
to st op the swaying by accele rating.
Observe speed limits. In some a reas, speeds fo r
vehicles towing tra ilers are lower tha n for regular
vehicles.
A lways apply brakes ear ly . When driving down­
hill, shift into a lower gea r to use the engine
braki ng effect to slow the vehicle. Use of the
brakes alone ca n cause them to overheat and fa il.
Coolant temperature
The coolant temperature gauge¢ page 8 must
be observed carefully. If the needle moves close
to the upper end of the scale, reduce speed im­
med iate ly and/or tu rn off the a ir cond itioner .
If the coolant temperatu re warning light . in
the instrument cluster starts flashing, p ull off
the road, stop and let the engine
idle for about
two minu tes to p revent heat build-up .
.&, WARNING
Anyone not properly res trained in a moving
vehicle is at a much greater risk in an acci ­
dent . Never let anyone ride in your car who is
not properly wear ing the restraints provided
by Aud i.
Trailer towing
information
Important to know
-
Your vehicle handles differently when towing a
trailer because of the addit iona l weight and dif­
ferent weight distribution. Safety, performance
and economy will greatly depend on how careful­
ly you load your tra iler and operate your rig.
Before you actually tow your trailer, pract ice
turning, stopping and backing up in an area away
from traffic. Keep pract icing u nti l you have be­
come completely fam iliar w ith the way your vehi-
cle-tra ile r combination behaves and respo nds . .,.

Fuel and Refueling
Fuel and Refueling
Fuel
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gaso line may not be available.
For more information on refueling your vehicle,
see
r::;, page 190.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 -90 AKI
188
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fue l with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock 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)
-Anti-knoc k index must be 87 AK I or higher.
- Blend must not contain more than 15% etha-
nol.
- Vehicles with flexib le fue l eng ine: blend must
not contain more than 85% ethanol.
Blend of gasoline and MTBE
-Anti-knock index must be 87 AKI or higher.
- Blend must contain not more than 15% MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-ove r, we suggest that you .,.

fill up at busy gas st ations where the season al
adjustment is more likely to be made in time .
(D Note
-Fu els con taining a high pe rcentage of etha­
no l such as ESQ and EBS may only be used in
vehicles with flexible fuel engines. Using high ethanol f uel in veh icles not equ ipped
with flexib le fue l engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may ca use corros ion and dam­
age to plast ic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the spec i­
fications, ask your service station o r its fuel
supplier.
- Do not use fue l for wh ich the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems result ing from the use of fuels differ­
ent from t hose specif ied a re not the respon­
s ibility of Audi and are not covered under
t h e New Veh icle o r the Emiss io n Control
System Wa rra nt ies.
- If yo u experience a loss of fue l economy o r
driveability an d pe rform ance prob le m s du e
to t he use of one of these fuel blends we
,
recommend that you switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to: ve hicles with flex ible fuel engine
You can recognize vehicles wi th a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Ve hicl es w ith flex ible f uel engines may be oper­
ated w ith b io -e thanol fuels such as EBS (85%
ethano l and 15% gasoline) or with un leaded gas­
oline (91 AKI/ROZ 95) . The ve hicle may a lso be

Fuel and R efueling
Your fuel consumpt ion w ill increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy conta ined per un it vol ume in ethanol.
Warming up the flexible fuel engine in low
temperature s
Due to the chemica l composition of b io -ethanol,
a certa in amount of fue l ends up in the engine o il
when driving short distances in very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up.
II Please warm up eng ine .
If the drive r message appears in the instr ume nt
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
- N ever fill wi th metha no l o r with a higher
percentage of b io -ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fuel can cause damage to the engine or to the fuel system.
- If you use on ly E85, it is recommende d to
fill the fue l tank complete ly w ith unleaded
premium g rade gasoline every 5,000 mi les.
- If you expe rience starting, rough id le or hes ­
itat ion d riveab ility prob lems, f ill the fuel
tank complete ly w ith unleaded p remium
grade gaso line and drive it norma lly until
t he gaso line is used. See your author ized
Audi dea ler if the problem persists.
- Inform your author ized Audi dealer that you
are ope rating o r have operate d the vehicle

steam or hot engine coolant by placing a
thick rag over the cap when you open the coolant reservoir .
- Do not remove the engine cover under any
circumstances . This increases the risk of
burns.
- If work on the fuel system or the electrical
system is necessary:
= Always disconnect the battery.
- Never smoke or work near heaters or open
flames. Fluids in the engine compartment
could start a fire.
- Keep an approved fire extinguisher imme­
diately available.
- To avoid electrical shock and personal injury
while the engine is running or being started,
never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair with
the engine running:
- First, fully apply the parking brake, move
selector lever of automatic transmission
to "P" (Park).
- Always use extreme caution to prevent
clothing , jewelry, or long hair from get-
194
ting caught in the radiator fan, V-belts or
other moving parts, or from contacting
hot parts. Tie back hair before starting,
and do not wear clothing that will hang or
droop into the engine.
