Winter tires
When driv ing in th e win te r, yo ur ve hicle with All Wheel Drive ha s an
advantage, even with regular t ires. In winter road conditions it may
b e advi sable to m ount win ter tires ( or all -s easo n tires) for impr oved

Off-Road dri ving?
Yo ur Au di d oes not have e nough gr ound clea ra nce to be use d as an
off -road vehic le . It is therefore best to avoid rough tracks and
u neven te rr ain as much as poss ible . Also refe r
to => page 2 45.
& WARNING
Alway s adjust your driving to road and traffic condition s. Do not
let the extra safety afforded by the all -wheel drive tempt you into
taking extra risks .
• Although the quattro ®all-wheel drive is very effective, always
remember that braking capacity is limited by tire traction. You
should therefore not drive at e xcessive speeds on icy or slippery
road surfaces.
• On wet road surfaces , be careful not to drive too fast be cause
the front wheels could begin to slide on top of the water (hydro ­
planing ). If this should occur , you will have no warning from a
sudden increase in engine speed as with a front -wheel drive
vehicle . Always drive at speeds which are adjusted to the road
conditions - risk of crash! •

Driving and environment
The first 1,000 miles (1,500 km) and
afterwards
New engine
The engine needs to be run-in during the first 1,000 miles
(1,500 km).
For the first 600 miles (1,000 kilometers):
Do not use full throttle.
- Do not drive faster than 3/4 of the top speed marked on
the speedometer.
- Avoid high engine speeds .
From 600 to 1,000 miles (1,000 to 1,500
kilometers):
- Speeds can gradually be increased to the maximum
permissible road or engine speed.
During and after break-in period
- Do not rev the engine up to high speeds when it is cold.
This applies whether the transmission is in N (Neutral) or
1n gear.
After the break-in period
- Do not exceed maximum engine speed under any
circumstances.
- Upshift into the next higher gear
before reaching the red
area at the end of the tachometer
scale => page 12.
Controls and equip­
ment Safety first
Vehicle operation
During the first few hours of driving, the engine's internal friction is
higher than later when all the moving parts have been broken in.
How well this break-in process is done depends to a considerable
extent on the way the vehicle is driven during the first 1,000 miles
(1,500 kilometers).
0 Note
Extremely high engine speeds are automatically reduced. However,
these rpm-limits are programmed for an engine well run-in, not a
new
engine.
~ For the sake of the environment
Do not drive with unnecessarily high engine speeds -upshifting
early saves fuel, reduces noise and protects the environment .•
New tires
If your vehicle is running on new tires, drive particularly
careful for the first 350 miles (500 kilometers) after fitting.
& WARNING
New tires tend to be slippery and must also be "broken-in". Be
sure to remember this during the first 350 miles (500 kilometers).
Brake
gently. Avoid following closely behind other vehicles or
other situations that might require sudden, hard braking.

New brake pads
Remember that new brake pads do not have a full braking
effec t during the first 250 miles (400 kilometers) after they
are i nstalled .
New brake pads have to be "burn ished in" befo re they have opti mal
grab =>& .
During the break -in period, you s hou ld avo id putti ng severe loads
on the brakes . Severe loads include, for examp le, sudden hard
braking, in particular at very h igh speeds or, for example, on moun ­
t ain passes .
& WARNING

Catalytic converter
It is very important that your emission control sys tem
(catalytic conver ter) is functioning properly to ensure that
y o ur vehicle is running in an environmentally sound
manner.
-Always use lead-free gasoline => page 267, "Fuel supply".
-Never run the tank down a ll the way to empty.
-Never put too much motor o il in your engine => page 278,
"Add ing eng ine oil -Neve r try to push -or tow -s ta rt yo ur vehic le.
The catalytic converter is an efficient "clean-up " device built into the
exhaust system of the vehicle. The catalyt ic converter burns many
of the po llutants in the exhaust gas before they are released into the
atmosphere.
T he exc lusive use o f un leaded fue l is critica lly important for the l ife
of the catalytic converter and proper functioning of the engine.
& WARNING
• Do not park or operate th e veh icle in ar eas wh ere the hot
ex hau st sys tem m ay come in contac t w ith dr y gra ss, bru sh , fuel
s pill or other material which can cau se a fire .
• Do not appl y additi ona l under coating or ru stpr oofing on or
ne ar the e xhau st m anifol d, ex haust pipe s, ca ta lytic converter or
he at shield s. Du ring dri ving , the sub sta nce u sed f or under coating
c ould overhe at and cau se a fir e.
0 Note
• Be aware that just one tank filling with leaded fue l wi ll already
ser iously degrade the performance of the catalyt ic converter.
• Do not exceed the correct engine oi l
level=> page 278.
• Do not drive until the fuel tank becomes comp letely empty . The
engine could misfire . Unburned fuel could also get into the exhaust
system and this could cause the catalytic conver ter to overheat .
• Do not turn off the ignition wh ile the vehicle is moving.
• Do not continue to operate your vehicle under these conditions,
as otherwise fuel can reach the cata lyt ic converter . This cou ld result
in overheating of the converter, requiring its rep lacement .
• To assure eff icient operat ion of the Em iss ion Control System:
- Have your vehicle maintained properly and in accordance with
the service recommendations in your Maintenance
& Warranty
booklet.

one half. Never drive faster than the posted speed limit and weather
conditions permit. •
Reducing unnecessary idling
Even when your car is just idling it burns up fuel.
- Shut the engine off when you are not driving the vehicle .
- Do not warm up the vehic le by letting the engine run at
id le .
It makes sense to shut off the engine in traff ic jams, when waiting
for tra ins 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 fue l 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 emiss ions are espec ially
high when the engine is warming up . So you should drive away as
soon as you sta rt the engine and avoid running at high rpms w hile
the engine is sti ll 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 id ling also produces heat, which could
resu lt in overheating or other damage to the vehic le or other
property .•
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
- Have your ve hicle serviced at regular intervals .
By having your vehicle regularly serviced by an Audi dealer helps to
ensure that it runs properly and economical ly . The cond ition of your
vehic le not only affects its safety and abi lity to hold its value, it also
affects
fuel consumpt ion .
Check your oil ea ch time you fill your t ank .
The amount of oil used is related to engine load and speed.
I t is norma l for the oi l consumption of a new engine to reach its
lowest value after a certain mi leage has been driven.
You must drive your vehicle about 3,000 miles (5,000 kilometers) before you can properly assess oil consumption .
This also applies to fue l consump tion and engine output .
0 Note
• Have your vehicle maintained properly and in accordance with
t he service recom mendat io n s in your Maintenance
& Wa rranty
booklet. Lack of proper ma intenance as well as improper use of the
vehic le wi ll impai r the function of the emission cont rol system and
cou ld lead to damage.
• Do no t alte r or remove any component of the Emission Contro l
System unless approved by the manufacturer .
• Do not alte r or remove any dev ice, such as heat shields,
switches, ignition wires, valves, which are designed to protec t your
vehic le's Emission Control System and other important veh ic le
components .•
Fewer short trips
Fuel consumption will alw ays be rel atively high on short
t r ips.
- Try to avo id driving short dis ta n ces wi th a cold engine. ~

Trailer lights
Trailer lights must meet all regulations. Be sure to check with your
authorized Audi dealer for correct wiring, switches and relays .
Mirrors
If you are unable to see the traffic behind you using the regular
outside mirrors, then you
must install extended mirrors. It is impor ­
tant that you
always have clear vision to the rear .
& WARNING
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. •
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 securely in place to guard
against shifting, be it forward, backward or sideways.
Never allow a passenger to ride in a trailer~ & in "Driving instruc­
tions".
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the sticker on the right door­
jamb. Inflate trailer tires to trailer and tire manufacturers' specifica­
tions .
Controls and equip­
ment Safety first Vehicle operation Lights
The
headlight settings should be checked with the trailer attached
before driving off. Adjust as necessary so that you can see the road
ahead but not blind oncoming traffic.
Check proper working of vehicle and trailer lights .
Power Supply
The power supply to the trailer is disconnected when the ignition
key is removed.
Safety chains
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 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 and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other vehicles.
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge.

W eig ht d is tri buti on
Towing a loaded tra iler wit h an empty car resu lts in a high ly
unstable distribution of weight . If this cannot be avoided drive at
ve ry low speeds only to avo id the risk of losing steering control.
A "ba lanced" rig is easier to operate and control. This means that
the tow vehicle should be loaded to the extent possible and permis ­
sib le whi le keeping the trailer as light as possib le under the circum ­
stances. Whenever possible, transfer some cargo to the luggage
compar tment of the tow veh icle whi le observi ng tongue load
requirements and vehicle loading considerations.
Speed
T he higher the speed, the more difficu lt it becomes for the driver to
contro l the rig . Do not drive at the maximum permissible speed.
Reduce your speed even more under unfavorable load, weather or
wind conditions -part icularly when going dow nh ill.
Reduce vehicle speed
immedi ately if the trailer shows the slightest
sign of swaying.
Do not tr y to stop the s waying by a cceler ating .
Observe speed limits . In some areas speeds for veh ic les towi ng
trai lers are lower than for regular vehicles.
Always app ly brakes early. When driving downhi ll, shift into lower
gear to use the engine braking effect to slow down the vehicle. Use
of the brakes alone can cause them to overheat and fail.
C oo la nt tempe ra tu re
The coola nt temperature gauge => page 13 must be observed care ­
ful ly. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or switch off the air conditioner.
If the coolant te mperature warning light in the instrument cluster
starts
flashing -~-, pul l off the road, stop and let the engine idle for
about two minutes to prevent heat build -up .
& WARNING
An yone not p rop erl y res trained in a mo ving vehicl e is at a much
gre ate r risk in an accident. Never let an yone rid e in your car who
is not p rop erl y wear ing the re stra int s pro vided b y Aud i. •
Trailer towing tips
Important to know
Your vehicle handles differently when towing a tra iler because of
the additional weight and weight distribution. Safety, performance
and economy wi ll great ly depend on how carefu lly you load your
trai ler and operate your rig.
Before you actual ly tow your tra iler, practice turning, stoppi ng and
backing up in an area away from traffic. Keep practicing unti l you
have comp letely become familiar with the way yo ur vehicle -trailer
combination behaves and responds .
Backing up is difficu lt and requires practice. Backing up with a
trai ler genera lly requ ires steering action oppos ite of that when
backing up your vehic le without a trailer.
Mainta in a greater distance between you r vehic le and the one in
front of you. You will need more room to stop.
To compensate for the trai ler, you wi ll need a larger than normal
t urning radius .
When passing, remember that you cannot accelerate as fast as you nor mally wou ld because of t he added load . Make sure yo u have
enough room to pass. After passing, al low plenty of room for your
trai ler before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane changes.

Cleaning and protection -
------------~---
High temperatures, as from exposure to intense sunlight, intensify
the corrosive effect particularly when humidity is high as well.
Under certain circumstances,
weekly washing may be necessary.
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash.
& WARNING
Always read and heed all WARNINGS and the information
~ page 254 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic car wash.
The vehicle paint is so durable that the vehicle can normally be
washed without problems in an automatic car wash. However, the effect on the paint depends to a large extent on the design of the
facility, the filtering of the wash water, the type of wash and care
material, etc. If the paint has a dull appearance after going through
the car wash or is scratched, bring this to the attention of the oper­
ator immediately . If necessary, use a different car wash .
Before going through a car wash, be sure to take the usual precau­
tions such as closing the windows and power roof* . Remove
antenna if applicable.
If you have installed additional accessories on the vehicle -such as
spoilers, roof rack, etc . - it is best to ask the car wash operator if
these should be removed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 254. •
Washing the vehicle by hand
A lot of water is needed when washing a vehicle by hand.
- Before you start washing, make sure you have read and
understood the
WARNINGS=> & in "General informa­
tion" on
page 254 .
- First soak all dried dirt until it is soft, then rinse it off.
- As you clean your vehicle, start with the roof and work
your way down to the bottom, using a sponge, a sponge
glove or a clean brush.
- Rinse the sponge or the sponge glove often, flushing it
clean each time.
- Use special car shampoo only for very persistent dirt.
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door sills and other
regions exposed to pick up road dirt. In this way, you will not
scratch the paint with coarse particles imbedded in the sponge the
next time you wash the car.
& WARNING
• Do not clean the underside of the chassis, fenders, wheel
covers, or other hard to reach parts without protecting your hands
and arms . You may cut yourself on sharp-edged metal parts.
