When charging at low voltages (e.g . w ith a
tri ckle charger ), the battery cables do not
have to be d isconnected first. Be fore charging
at
high voltages, i.e. " fast charging ", you
must disconnect both cables. In e ither case,
follow the instruct ions from the ma nufacturer
of the charger .
Fastcharging a battery is
dangerous c:> .&. in

-Never mount used tires on yo ur vehicle if
yo u 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 tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .

Technical Modifications
Our guidelines must be complied with when technical modifications are made .
Always consult an authorized Audi dealer be­
fore starting work on any modifications.
This will help ensure that vehicle function,
performance and safety are not impaired
¢ &. .
Attempting to work on electronic components
and the software used with them can cause
malfunctions. Because of the way electronic
components are interconnected with each
other, such malfunctions can also have an ad­
verse affect on other systems that are not di­
rectly involved. This means that you risk both
a substantial reduction in the operational
safety of your vehicle and an increased wear of
ve hicle parts ¢
A:,..
Author ized Audi dealers will perform th is
wo rk in a professiona l and competent manner
or, in special cases, refer you to a professional
company that specializes in such modifica­
tions .
A WARNING
Improper repairs and modifications can
change the way vehicle systems work and
cause damage to the vehicle and serious
personal injury.
If emergency repairs must be performed
elsewhere, have the vehicle examined by
an authorized Audi dealership as soon as
possible.
