Vehicle battery
The term "vehicle battery" refers to the 12 Volt
battery in your vehicle.
Not running the vehicle for long periods of
time
If yo u do not dr ive you r vehicle for seve ral days or
weeks, e lectrical equipment is gradually sca led
back or switched off. This reduces ene rgy use and
ensu res the veh icle w ill be able to start after long
pe riods of time¢
page 147. Some convenience
functions, suc h as inter ior light ing or power seat
adjustment, may not be available under certa in
circumstances. These convenience funct ions w ill
be ava ilable again once you switc h the ign ition on
and start the engine.
Even when electrical equ ipment is switched off,
the equ ipment can still d rain the vehicle battery
if the vehicle is not drive n for long per iods of
time. Deep d rain ing results in a chemical reaction
that des troys the inside of the vehicle b attery.
The vehicle batte ry must be charged every mont h
to reduce the risk of this happening ¢

Contact an author ized Audi dealer or authorized
Aud i Service Facility for more information.

& WARNING
- A highly explosive mixture of gases can form
when charging batter ies . Only charge the
vehicle battery in well-vent ilated areas .
- A drained vehicle battery can freeze at tem
peratures a round 32 QF (0 QC) . A frozen or
thawed veh icle battery must not be charged
and must not be used anymore. If ice fo rms,
the battery housing ca n crack and ba tte ry
electrolyte can lea k out, which increases the
risk of an explosion and chemi cal bu rns.
Contact an authorized Au di dea le r o r au
tho rized Audi Serv ice Facility fo r more info r
mation.
- Do not connect o r disconnect the ch arging
cable while charg ing because this increases
t h e risk of an exp losion.
(D Tips
- Only charge the vehicle battery through the
con nections in the engine compartment .
- Read a ll of t he manufacture r's ins tructions

(D Note
- The concentration o f anti -freezing agent
must be adjusted to the ve hicle operating
conditions in the respective cl imate. A con
centration that is too high can lead to vehi
cle damage.
- Never add radiator anti-freeze or other addi tives to the washer fluid.
- Do not use a glass cleaner t hat contains

General information
~check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob
jects from the tire tread.
~ If driving over curbs or similar
obstacles, drive slowly and ap proach the curb at an angle.
~Have faulty tires or rims re
placed immediately.
~ Protect your tires from oil,
grease and fuel.
~ Mark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
~Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
_&. WARNING -
-Never drive faster than the maximum permitted speed
for your tires. This could cause
the tires to heat up too much.
This increases the risk of an
accident because it can cause
the tire to burst .
-Always adapt your driving to the road and traffic condi-
330
tions . Drive carefully and re
duce your speed on icy or slip
pery roads . Even winter tires
can lose traction on black ice.
(@ Note
-Please note that summer and
winter tires are designed for
the conditions that are typical
i n those seasons . Aud i recom
mends using winter tires dur
ing the winter months . Low
temperatures significantly de
crease the elasticity of summ
er tires, which affects traction
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or chromed rims must not be used in winter driving condi
t ions. The surface of the r ims
does not have sufficient corro
sion protection for this and
could be permanently dam
aged by road salt or similar
substances.
