192 Smart Technology
To restore the balance of energy, components
that require large amounts of energy are tem­porarily sca led back or switched off . Heating
systems in particu lar require a great deal of
energy. I f you notice, for example, that the
seat heating* or rear window defroster is not
working, then it has been temporarily reduced
or sw itched off . These systems are available
again as soon as the energy ba lance has been
restored.
In addition, you may notice that the idle
speed has slightly increased . That is normal
and no cause for concern . Due to the in­
creased idling speed, the additional required
energy will be generated and the battery will
be charged.

Caring and cleaning
General information
Regular, proper care helps to maintain your
vehicle's val ue . It can also be a requirement
when submitting warranty claims for corro­
sion damage and paint defects on the body.
The necessary care products can be obtained
from your a uthorized Audi dea ler . Read and
follow the instructions for use on the packag­
i ng.
A WARNING
- Us ing clean ing and care products incor­
rectly can be dangerous to your hea lth .
- Always store cleaning and care products
out of reach of children to reduce the r isk
of po isoning.
-
@ For the sake of the environment
- Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not d ispose of leftover cleaning and
care products with household trash.
Car washes
T he longer that deposits such as insects, bird
droppings, tree sap or road sa lt rema in on the
veh icle, the more the surface can be dam­
aged . High tempe ratures such as those
caused by sunlight increase the cor rosive ef­
fect .
Before washing, rinse off heavy depos its with
p lenty of water .
Also, was h the underside of your ve hicle once
road salt stops be ing used for the season.
P ressure wash ers

tires, rubber hoses, insulating material, sen ­
sors * or camera lenses* . Keep a distance of at
l east 16 inches (40 cm).
Do not remove snow and ice with a p ressure
washe r.
Neve r use rotary nozzles or high pressure noz­
z les.
T he wate r temperature must not be above
140
°F (60 °() .
Automatic car washes

220 Checking and Filling
Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte­
nance. With
high outs ide temperatu res or
long daily drives we recommend that you have
the electro lyte level checked by a service fa­
cility. The e lectrolyte level shou ld also be
checked each time the battery is charged
c:>page222.
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.
With certain types o f airbag deployment, the
battery is disconnected from the vehicle elec ­
trica l system for safety reasons
c;, .&. in Re­
pair , care and disposal of the airbags on
page 156.
Disconnecting the battery terminals
Some vehicle functions such as power win­
dows are unavai lable if the battery termina ls
are d isconnected. These functions have to be
relearned after the battery terminals are con­
nected again. To prevent this, the battery
should only be disconnected from the vehicle
electrical system when absolutely necessary
for repairs .
To reprogram the functions, proceed as fol­ lows:
Function Reprogramming
Power window one-c;, page 40, Correcting
touch up/down power window mal-
function functions
Remote control key If the vehicle does not
or react to the key, it
convenience key must be synchroni zed
c:>page 33
Digital clock c:>page 10
ESC indicator light The indicator light
goes out after driving
a few meters
Vehicles not driven for long periods
If you do not drive your vehicle over a period
of severa l days or weeks, e lectrica l compo­
nents are gradually sca led back or switched
off. This reduces energy consumption and
maintains starting capability over a longer pe­
riod
c;, page 190. Some of the conven ience
functions may not operate, such as the interi­
or lights or power seat adjustment. The con ­
venience functions will be availab le aga in
when you switch on the ignition and start the
engine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop. This
is because more power is also consumed wh ile
sta rting, and the headlights, rear window de­
fogger, etc. , are used more often.
Avoid unnecessary power consumpt ion, par­
ticularly in city traffic or when traveling only
short distances. Let your authorized Aud i
dealer check the capacity of the vehicle bat­
tery before winter sets in ~ page 222. A well
charged battery will not on ly prevent starting
problems when the weather is cold, but will
also last longer.
A WARNING -
-Work on the battery requ ires expert
know ledge. Contact your authorized Audi
dealer qualified repair facility for infor­
mat ion regarding the vehicle battery.
There is a risk for chemical burns or ex­
p losions.
- Never open the vehicle batte ry . Do not
try to change the battery electrolyte lev­
el. Otherwise explosive gas will escape
from the battery and increase the risk of
an explosion .
(i) Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery should be removed and
stored where it w ill not freeze. This will ..,.

226 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note
- Please note that summer and winter
tires are designed for the cond itions that
a re typ ica l in those seasons. Aud i recom­
mends using w inter t ires d uring the win-
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those standard items which may be rep laced)
of automatic transmission, power steering,
power brakes, power windows, power seats,
radio, and heater, to the extent that these
items are availab le as factory-installed equip­
ment (whether installed or not).
A spect ratio
means th e ratio of the height to the width of
the tire in percent. Numbers of 55 or lower in­
d icate a low sidewall for improved steer ing re­
sponse and better overall handling on dry
pavement .
Bead
means the part of the tire th at is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim.
Bead s eparation
means a breakdown of the bond between
components in the bead.
Cord
means t he strands forming the plies in the
tire. ter months.
Low tempe ratu res signifi­
cantly decrease the elasticity of summer
tires, which affects traction and braking ability. If summer tires are used in very
co ld temperatures, cracks can form on
the tread bars, resu lting in permanent
tire damage that can cause loud driving
noise and unbalanced tires. Aud i is not
responsib le for this type of damage.
- Burn ished, polished or chromed rims
must not be used in winter weather. The
surfa ce of the rims does not have suff i­
c ien t cor rosion prote ct io n for this and
co uld be pe rmanen tly damaged by road
salt or simi lar substances. This damage
is not cove red by war ranty.
Cold tire inflat ion pre ssure
mea ns the t ire press ure recommended by the
vehicle manufacturer for a tire o f a des ignated
size that has not bee n driven for more than a
coup le of miles (ki lometers) at low speeds in
the three hour period before the tire press ure
is measured or adjusted.
Curb weight
means the weight of a motor vehicle w ith
standard equipment including the maximum
capacity of fuel, o il, and coolant, air condi­
tion ing and additional weight of optional
equipment.
E x tra load tire
means a tire design to operate at higher loads
and at higher inflation pressures than the cor­
responding standard tire. Extra load tires may
be identified as "XL", "xl", "EXTRA LOAD", or
"RF" on the sidewall.
