If it is difficult to turn the key after you have
inserted it into the ignition lock, turn the
steering wheel back and forth. This will take
the load off the steering lock mechan ism and
you will be able to turn the key freely and
start the engine. On vehicles with a diesel en­
g ine*, the system can preheat in this pos ition .
Starting the engine @
In this position the engine starts. While the
engine is starting, the power supply to the
headlights and other electrical consumers is
temporarily interrupted to conserve battery power. After the engine has started, release
the key and it will return to position @.
Before the starter can be operated again the
key must be turned back to position @. The

174 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 durability,
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 reasons, always follow the operating
and drivi ng in str uctions provided and use
common sense.
Technical requirements
Traile r hitch
Use a weight-carrying hitch conforming to the
gross trailer weight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted securely on the ve hicle's chassis at a
technically sound location. Use only a trailer
h itch with removable ba ll mount. Always
check with the tr ailer hitch manufac turer 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 that
it does not interfere with the impact-absorb­
ing bumper syst em. No modifications should
be made to the vehi cle exhaust and brake sys ­
tems. From time to time, check th at a ll hitch
mo unt ing bo lts remain securely fastened.
When you are not towing a trailer, remove the
tra iler hitch ball mount. This prevents the
h itch from causing damage sho uld your ve hi­
cle be str uck from behind
¢ A .
Tire pressure
When tow ing a traile r, inflate the t ires of your
ve hicle to the co ld tire pressure listed under
"Full load"on the stick er on the rig ht doo r- jamb. Inflate trailer tires to trailer and tire
manufacturers' specifications.
Lights
T he headlight set tings sho uld be checked with
t h e trai le r attached before d riving o ff. Have
the headlights adjusted as necessary so tha t
yo u can see t he road ahead b ut not blind on­
coming traffic.
Check to make sure bo th ve hicle and tr ailer
lights are wo rk ing properly .
Engine cooling system
T owing a t railer makes the engine work hard­
er.
It i s impo rtant that the cooling system's
performance stands up to the additional
stra in. Make sure tha t the cooling sys tem has
enough fluid.
Trailer brakes
If your trailer is equipped with a brak ing sys­
tem, c heck to be sure t hat it conforms to all
regula tions.
The trailer hyd raulic brake system must not be
directly connected to the vehicle's hydraulic
brake system.
Safety ch ains
Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle. Leave enough slack in the cha ins to per­
mit turning co rne rs. When yo u in stall safety
c h ains, ma ke sure they will not drag on the
r oad when you a re driving.
The chains should cross under the t railer
tong ue to prevent it from dropping in case of
separation from the h itch.
Trailer lights
Trai ler lights must meet all regulations. Be
sure to check w ith your authorized Audi dealer
for correct w ir in g, sw itches and re lays .
Mir rors
If you are unable to see the traffic behind you
us ing the regular outside mirrors, then you

CD Note
You should remove debris (such as insects)
from the headlight lenses on a regular ba­sis, for example when refueling your vehi­
cle. Never clean the headlights with a dry
cloth or sponge . Use a wet cloth or
sponge.
It is best to use soapy water .
Automatic car wash
The vehicle can be washed in almos t any
modern automatic 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 de­
sign 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 operator immedi­
ately. If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and panoramic sliding sunroof*. Re­ move 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.
A WARNING
Always read and heed all WARNINGS and other information

using a sponge, a sponge glove or a clean
brush.
"" Rinse the sponge or the sponge glove often,
flushing it clean each time.
11-Use special car shampoo only for very per­
sistent dirt .
11-Rinse the car thoroughly with water .
11-Use a chamois leather to gently wipe the ex-
terior dry.
Use a separate sponge for cleaning the
wheels, door sills and other regions exposed
to 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.
A WARNING
= -
-Do not clean the underside of the chas-
sis, fenders, wheel covers , or other hard
to reach parts without protecting your hands and arms . You may cut yourself on
sharp-edged metal parts.
- Always read and heed all WARNINGS and
other information

CD Note
- Never try to remove dirt, mud or dust if
the surface of the vehicle is dry. Never
use a dry cloth or sponge, since this
could scratch your vehicle's paint or win­
dows.
- Never wash your car in bright sunlight.
Drops of water act as magnifying lenses
and may damage your paint .
- When you wash your car in the winter: if
you rinse your vehicle with a hose, be
careful not to aim the stream of water
directly at locks, or at door or hatch
openings -they can freeze shut.
- Never use sponges designed to remove
insects, or any kitchen scouring sponges
or similar products. They can damage
your paint finish.

180 Cleaning and protection
@ For the sake of the environment
In the interest of the environment, the ve­
hicle should on ly be washed in special
wash bays.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules .
~ Before using the power washer, make sure
you have read and understood the WARN­
INGS
c::> A in General information on
page 178 .
~ Always fo llow the operating instructions for
the power washer.
~ Make sure tha t the jet o n the spray hose
produces a "fan shaped spray".
~ Do not ho ld the spray nozzle too close to
soft materia ls.
When clean ing the veh icle wit h a power wash­
er
always fo llow the operating instructions .
This applies particularly to the
oper ating
pressu re
and the sp ray ing distance . Maintain
a sufficient distance to soft materials such as
rubber hoses and sound/vibrat io n deadening
materials (part icularly on the underside of the
engine hood). Do not use a jet wh ich sprays
water in a
dire ct stream or one that has a ro ­
ta ting
jet.
Water temperature should not exceed 140 °F
(60 °().
A WARNING
Never wash tires w it h a je t that sprays wa­
t er in a direc t stream. This cou ld cause in­
visib le damage to the tires and weake n
t hem, even if the spray is from a re latively
long distance and for a short time . Dam­
aged and weakened t ires can fa il and cause
accidents and persona l injury.
([) Note
To avo id damag ing your vehicle, always
make sure t hat there is sufficient distance between the spray head and soft materia
ls
li ke rubber hoses, plastic parts and sound­
deaden ing mater ials. Never aim the spray
head at the same point for a long time.
This also applies to cleaning headlights
and painted bumpers. Remember: the
closer the nozzle is to the surface of the
mater ia l, the greater the stress on the ma­
te rial.
Waxing and Polishing
Waxing
A good wax coating protects the vehicle pain t
to a la rge ex ten t agains t the envi ronmental
f actors lis ted under
c::> page 178, Washing and
even against sli ght scratches .
You can use a liquid car wax to prote ct yo ur
paint as soon as one wee k afte r you r vehicle
has been delivered .
E ven if you regu larly use a
wa xing p rocess in
a ut oma tic car washes, we recommend tha t
yo u manually apply a coat o f wax to g ive the
paint extra protection, part icu larly if water no
l onger beads on t he clean paint.
Protect plast ic body parts with car wax in the
same w ay as the veh icle body.
D ur ing warm weather dead insects tend to
collect on the front bumper and on the fo r­
wa rd area of the hood. They are much easier
to remove from p aint th at is waxed
often.
Polishing
Polish your vehicle only if the paint has lost its
sh ine and the gloss cannot be broug ht back
with wax.
If the polish used does not contain preserva­
t ive compou nds, the paint must be waxed af ­
te rwards .
A WARNING
Always read and heed all WARNI NGS and
other info rmation
