Reducing unnecessary =citing
Even when your car is just idling it burns up fuel.
- Shut the eng ine off when you are not driving the vehicle .
- Do not warm up the vehicle by letting the engine run at
idle.
It makes sense to shut off the engine in traffic jams, when waiting
for trains to pass at rai lroad crossings , or at traffic lights that have
long waits on red. Turning the engine off for just 30 -40 seconds
saves more fuel than is burned starting the engine again .
It takes a long time for the engine to warm up fu lly when it is
running at idle. However, wear and noxious emissions are especially
high when the engine is warming up. So you should drive away as
soon as you start the engine and avoid running at high rpms while
the engine is still warming up.
0 Note
Do not leave engine idling unattended after starting . If warning
lights should come on to indicate improper operation, they would
go unheeded. Extended idling also produces heat, which could result in overheating or other damage to the vehicle or other
property .•
Regu1ar ma1--.tenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your vehic le serviced at regular intervals . By having your vehicle regularly serviced by an authori

dea ler helps to ensure that it runs properly and economica lly. The
condition of your vehicle not only affects its safety and ability to
hold its value, it a lso affects

C he ck your oil each time you fill your t ank .
The amount of oil used is related to engine load and speed.
It is norma l for the oil consumption of a new engine to reach its
lowest va lue after a certain mileage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
T his also applies to fuel consumption and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
the service recommendations in your Warranty
& Maintenance
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impair the function of the emission control system and
cou ld lead to damage.
• Do not alter or remove any component of the Emiss ion Control
System unless approved by the manufacturer.
• Do not alter or remove any device, such as heat shields,
switches, ignition wires, valves, which are designed to protect your
vehicle 's Em ission Control System and other important vehicle
components .•
Fewer short tr ips
Fuel consumption will always be relatively high on short
trips.
- Try to avoid driving short dista nces wi th a cold engine. _,

The engine and catalytic converter have to reach their optimal oper­
ating temperature to reduce fuel consumption and noxious emis ­
sions effectively.
Just after starting, a cold engine in a mid -size car only achieves a
fuel economy of 6-8 miles per gallon (30-40 1/100km) . After about a
half a mile, fuel economy climbs to 12 mpg (201/100 kml. After about
2.5 miles (4 km), the engine is at its proper operating temperature
and fuel economy has reached a normal level. So you can see that
you should avo id short tr ips whenever possible.
The outside temperature is also critical in this regard. Your car
consumes more fuel in the winter than in the summer. •

Trailer towing
Driving with a trailer
Genera l information
Your Audi was designed primarily for passenger transpor­
ta tion.
If you plan to tow a trailer, please remember that the add itional load
wi ll affect durability, economy and performance.
Trai ler towing no t only places more s tress on the vehicle, it a lso ca lls
for more concentration from the driver.
F or this reaso n, always fol low the operating and driving instructions
prov ided and use common sense.
(D Note
If you are going to tow a tra iler, you must activate the trailer opera ­
tion mode =>
page 211, "Towing a trailer".
Technical requirements
Trailer hitch
Use a we ight-carry ing hitch conforming to the gross tra iler weig ht.
T he hitch must be suitable for your vehic le and trailer and must be
m ounted secure ly on the veh icle's chassis at a
technically sound
location. Use only a trailer hitch with a removable ball mount.
Always check with the trai ler hitch ma nufacturer to make sure that
you are using the correct hitch .
Do not use a bumper hitch.
The hitch must be instal led in such a way that it does not in terfere
with the impact-absorbing bumper system. No modifications shou ld be made to the vehicle exhaust and b rake systems . Fro m

time to time, check that all hitch mounting bolts remain securely
fastened .
When you are not towing a trai ler, rem ove the t railer hi tch bal l
mount. This prevents the hitch from causing damage should your
vehicle be struck from behind =>
&.
Trailer bra kes
If your trai ler is equipped with a b raking system, check to be sure
that it conforms to all regulations.
The tra iler hydraul ic bra ke system must not be directly co nnecte d to
the veh icle's hydrau lic brake system=> &.
Safety chains
Always use safety chains between your vehicle and the trailer.
Trail er lights
Trai ler lights must meet a ll regulations. Be sure to check with your
au thorized Audi dea ler for correct wiring, switches, an d relays.
Mirrors
If you are unab le to see the traff ic behind you using the regular
outside mirrors, then you
must instal l extended mirrors. It is impor ­
t ant that you
always have clear v isi on to the rear.
& WARNING
• If a trailer has electrical brake s please note that the se brakes
are not act ivated by the fa ctory-fitted control unit -ris k of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking , the hitch could fly forward and injure
you or your passengers .

pillar. On Canada vehicles, the tire pressure label is located either on
t he driver's side 8 -pillar or inside the fuel fil ler flap. Inflate trailer
tires to trailer and tire manufacturers' specifications.
L ight s
The head light settings should be checked with the trailer attached
before driving off . Check to make sure both vehicle and trai ler lights
are working properly.
Sa fety c hain s
Be sure trailer safety chains are properly connected from the trailer
to the hitch on the vehicle . Leave enough slack in the chains to
permit turning corners. When you insta ll safety chains, make sure
they will not drag on the road when you are driving .
The chains should cross under the tra iler tongue to prevent it from
dropping in case of separation from the hitch.
0 Note
If you are going to tow a traile r, you must activate the trailer opera ­
tion mode =>
page 211, "Towing a trailer" .
Driving instructions
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the fo llow ing:
- Do not tow a loaded trailer when your car i tse lf is not
loaded .
- Be especia lly careful when passing other vehicles .
- Observe speed l imits.
- Do not drive at the maximum permiss ible speed .
Controls and equip­

Tr
aile r t owing
Always apply brakes early .
- Monitor the temperature gauge .
Weigh t dis tr ibution
Towing a loaded trailer wi th an empty car results in a highly
unstable dis tribution 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 permis ­
sib le, while keeping the trailer as light as possib le under the circum ­
stances . Whenever possible, transfer some cargo to the luggage
compartment of the tow vehicle whi le observing tongue load
requirements and vehicle loading considerations .
Speed
The higher th e speed, the more difficu lt it becomes for the driver to
control the rig . Do not drive at t he maximum pe rmissible speed.
Reduce your speed even more
if load, weather or wind conditions
a re unfavorable -particularly when going downhil l.
Reduce vehicle speed
i mmedi ate ly if the trailer shows the slightest
sign of swaying.
Do not tr y to s top the swaying by accelerating .
Observe speed limits . In some areas, speeds for vehicles towing
trailers are lower than for regular vehicles .
Always apply brakes early. When driving downhill, shift into a lower gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fa il.
Coo lant t emperatu re
The coolant temperature gauge=> page 13 must be obse rved care ­
ful ly. If the need le moves close to the upper end of the sca le , reduce
speed immediately and/or turn off the air conditioner .
If the coolant temperature warning light in the instrument cluster
starts f lashing
- f- , pul l off the road, stop and let the engine idle for
about two minutes t o prevent heat build -up.

Fuel supply and filling your fuel tank
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 10% 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 especially well for
winter or summer driving. During seasonal change -over, we suggest
that you fill up at busy gas stations where the seasonal adjustment
is more likely to be made in time.
0 Note
• Methanol fuels which do not meet these requirements may
cause corrosion and damage to plastic and rubber components 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 specifications, ask your service station or its fuel
supplier.
• 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 responsi ­
bility 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 problems 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 manufacturers 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 fuel systems clean,
they are not equally effective.
Audi recommends using TOP TIER Detergent Gasoline. For more
information on TOP TIER Detergent Gasoline, please go to the offi­
cial website (www.toptiergas.com).
After an extended period of using inadequate fuels, carbon deposit
build-ups can rob your engine of peak performance.

Damage or malfunction due to poor fuel quality is not covered by
the Audi New Vehicle Limited Warranty. •

current list of oils (manufacturers, brand names etc.) that conform
t o Audi oi l standard VW 502 00 .
Changin g the engine oil
The engine oil and oil filter must be changed according to the
mi leage (ki lometers) and time intervals specified in your vehicle's
Warranty
& Maintenance booklet. Do not exceed these interva ls -
harmful deposits from old engine oil can reduce engine perfor­
mance and can lead to expensive engine repairs.
Changing the oi l at the recommended intervals is so very important
because the lubricating prope rties of oi l decrease gradual ly during
normal vehicle use . If you are not sure when you have your oil
changed, ask your author ized Audi Serv ice Advisor.
Under some circumstances the engine oil should even be changed
more frequently. Change oil more often if you dr ive mostly short
distances, operate the vehicle in dusty areas or mostly under stop ­
and -go t raffic conditions, or when you use your vehicle where
temperatures stay be low freezing point for long per iods.
Detergent additives in the oil 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.
Damag e or malfunctions due to lack o f mainten anc e
It is essentia l that you change your oi l at the recommended interva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover damage or ma lfunctions due to failure to follow recommended
main tenance and use requirements as set forth in the Aud i Owner's
Manual and Warranty
& Maintenance booklet. Your dealer wi ll have
t o deny warranty cove rage unless you present to the dealer p ro o f in
the form of Service or Repair Orders that all schedu led maintenance
was pe rformed in a timely manner. •
Engine oil consumption
The engine in your vehicle depends on an adeq uate
amount of oil t o lubric ate and c ool all of its m oving parts.
In order to provide effective lubrication and coo ling of interna l
engine components, al l interna l combustio n eng ines consume a
certain amount of oil. Oil consumption varies from engine to engine
and may change significant ly over the life of the engine . Typ ically,
engines with a specified break-in period (see=>
page 2971 consume
more oil du ring the break-in period than they consume after oil
consumption has stabi lized .
Unde r normal conditions, the rate of oil consumption depends on
the quality and v iscosity of the oil, the RPM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
cond itions. Fur ther factors are the amount of oil di lu tion from wate r
condensation or fue l residue and the oxidation leve l of the oi l. As
any engine is subject to wear as mileage bu ilds up, t he oil consump ­
tion may increase over time until replacement of worn components
may become necessa ry .
With all these variables coming into play, no standard rate o f oi l
consumption can be established or specified . There is no alternative
t o regula r and frequent checking of the oil level, see
Note .
If the yel low engine oil level warning symbo l in the instrument
clus ter lights up, yo u should check the oil level as soon as
possible
with the oil dipstick=> page 335. Top off the oil at your
ea rliest convenience =>
page 336.
& WARNING
Before you check anything in the engine compartment , always
read and heed all WARNING S
=> & in "Working in the engine
compartment " on
page 331.
