sponges to prevent scratches. It is best
to use soapy water .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the head lights. Only use
we t cloths or sponges to prevent
scratches . It is best to use soapy water .
@) For the sake of the environment
Only wash the vehicle in facilit ies specially
designed for that purpose. Th is w ill reduce
the risk of d irty water contaminated w ith

some areas, wash ing vehicles outs ide of
these facilities is prohib ited.
Washing your vehicle with a power

page 202.
• Always fo llow the operating instructions for
the power washer.
• Make sure that the jet o n the spray hose
produces a "fan shaped spray" .
• Do
not hold the spray nozzle too close to
soft materia ls .
Keep a d is tance from soft materials such as
rubber hoses o r insulat ing mater ial as we ll as
sensors and camera lenses .
When cleaning t he vehicle wit h a power wash­
er
always fo llow the operating instructions .
This applies particularly to the operating pres­
sure and the spraying distance . Do not po int
the spray direc tly at the sea ls around the s ide
windows, aro und t he doors, on the re ar lid or
on the sunroof* . Likew ise, do not point it di­
rectly at tires, r ubber hoses, ins ulation mate­
rial or sensors
q page 205. Hold the spray nozzle at least 1.3 ft (0.4 m) away from the
vehicl e.
Do no t use a high-pressu re power was her to
remove snow and ice .
Do not use a jet which sprays water in a d irect
st ream o r one that has a rotating je t.
Water temperature should not exceed 140 °F
(60 °() .
A WARNING ,..__
Neve r wash t ires with a jet that sprays wa­
ter in a direct stream . Thi s could cause in­
v is ible d amage to the t ires and weaken
them, even if the spray is from a relative ly
l ong distance and for a short time . Dam ­
aged and wea kened tires can fail a nd cause
accidents and personal in jury.
(D Note
To avoid damaging yo ur vehicle, a lw ays
make sure tha t the re is sufficien t distance
betwee n the spray head and soft materia ls
lik e rubbe r hoses, plast ic parts and sound ­
deaden ing mater ia ls as well as sensors
and camera lenses. Never a im the spray
head at the same point fo r a long time.
This also app lies to cleaning headlights

230 Check ing and filling
Have the battery checked when you take your
vehicle in for service. You are well advised to replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons¢
& in Re­
pair, core and disposal of the airbags on
page 159.
Disconn ect ing the battery terminal s
Some vehicle functions (power window regu­
lators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
Vehicles not dri ven fo r lo ng p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and main ­
tains starting capabil ity over a longer period
¢ page 192.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again when you
turn on the ignition and start the eng ine.
Winter operati on
During the winter months, battery capacity
tends to decrease as temperatu res drop . This
is because more power is also consumed while
start ing , and the headlights, rea r window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in c ity traffic or when traveling on ly
short distances. Let you r authorized Audi
dea ler check the capacity of the vehicle bat ­
tery before winter sets in
¢ page 232. A well
charged batte ry w ill not only prevent sta rting
prob lems when the weather is cold, but wi ll
a lso last longer.
(D Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery sho uld be removed and
stored where it w ill not freeze . This will
prevent it from be ing damaged and having
to be replaced .
