Always app ly bra kes early . When driving
downhill, shift into lower gear to use the en­
g ine braking effect to slow down the vehicle.
Use of the brakes alone can cause them to
overheat and fail.
Coolant temperature
The coolant temperature gauge ¢ page 11
must be observed carefully. If the needle
moves close to the upper end of the scale, re­
duce speed immed iate ly and/or switch
off the
a ir cond itioner.

ing veh icle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not prope rly wear ing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle handles different ly when towing
-
a trailer because of the addit io nal weight and
weight distribution . Safety, performance and
economy w ill greatly depend on how carefu lly
you load your trai ler and ope rate your rig .
Before you actually tow your trailer, practice
turn ing, stopp ing and back ing up in an area
away from traffic. Keep practicing until you have comp letely become fam iliar w ith the way
your ve hicle-trai ler comb ination behaves and
responds .
Backing up is d iff icu lt and requires practice .
Backing up with a tra ile r genera lly requ ires
steer ing act ion opposite of tha t when backing
up your veh icle without a trailer .
Ma intain a g reater distance between your ve­
h icle and the one in fro nt of you. You will need
mo re room to stop. To compensate for the trailer, yo
u will need a
larger than normal turning radius.
When passing, remember that you cannot ac ­
ce le rate as fas t as you no rma lly would be­
cause of the added load. Make sure yo u have
enough room to pass . After passing, a llow
plenty of room for your trailer before chang ­
ing lanes again.
Avoid jerky starts , sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break -in
period of your vehicle.
- If you tow a trailer, yo ur Audi may re­
quire more frequent maintenance due to
the extra load ¢
page 2 59.

not be avoided, do so only after doing the fol­
lowing:
When parking:
.,. App ly the foot brake.
.. Have someone p lace cho cks under both the
veh icle and the trailer wheels.
.. With chocks in place, slowly release the
brakes unti l wheel b locks absorb th e load.
.. Turn the whee ls towards the cu rb.
.. App ly the parking brake.
.. Place an automat ic transm ission in

Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing .
How often this is required depends on:
- How much the vehicle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasona l and weather conditions
- Environmental i nfl uences
The longer b ird droppings, insects, tree resin,
r oad and industrial gr ime, tar, soot, road salt
and other mater ials remain on the veh icle
body, the mo re lasting their destructive ef­
fects w ill be .
High temperatures , as from expos ure to in­
tense sun light, intensify the corrosive effect
part icularly when hum idity is high as well.
Under certa in circumstances,
we ekly washing
may be necessary. Unde r other cond itions, a
monthly washing and waxing may be ade­
quate.
After the winter, the unders ide of the vehicle
should be thoroughly washed, preferably in a professional car wash .

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.

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 .

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.

and mir rors is to use a brush. Use a non -abra­
sive
pla stic ice scraper -better still, a spray
deicer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax since these can interfere with
the function of the windshield wiper blades (chatter).
O il, grease or silicone residue can be removed
with
glass cle aner or silicone remo ver. How­
ever, wax residue req uires the use of a specia l­
ly form ulated solvent. P lease contact your au­
