CD Note
Never use a fast charger as a booster to start
the engine . This will serious ly damage sensi­
tive electronic components, such as control
units, relays, radio, etc., as well as the battery
charger.
Battery replacement
T he new battery must have the same specifica­
t ions and dimensions as the original equipmen t
bat tery.
Int elli g ent en ergy managem ent in your vehicle is
responsible for distributing the electrical energy
throughout your vehicle
r=> page 195. The intelli­
gent energy management system will keep the
engine battery charged better than veh icles w ith­
out this system . To make sure the addit ional
e lectrical energy is avai lab le once again after you
have changed the battery, we recommend that
you install batteries of the same type and manu­ facture on ly (the same as those installed at the
time your vehicle was delivered). Specifications
are listed on the battery housing. Your author­
i z ed dealer must code the battery in the energy
management system to enable you to use the en­
ergy management functions correctly after re ­
placing the battery .
The new battery must have the same capacity,
voltage (12 volts) , amperage, construction and
plug sealing .
When installing the battery, make sure the igni­
tion and all electrical consumers are sw itched
off.
CD Note
- Make sure the ventilation hose on the s ide
of the battery is connected, otherw ise
fumes or battery ac id can leak out.
- Vehicles with the Start-Stop-System* are equipped with a special cycle-proof AGM battery . Installing a d ifferent type of bat­
tery can cause problems in the vehicle elec -
234
trical system. When replacing the vehicle
battery, always install one with the same
specifications as the original battery .
- Battery mounts and clamps m ust always be
secured correctly.
- Read and follow the warnings under
¢ page 231, Working on the battery before
performing any work on the battery .
@ For the sake of the environment
Because of the p roblem of proper disposal of
a battery, we recommend your authorized
A udi dealer change the battery for you . Bat­
teries contain sulfur ic acid and lead and must
a lways be disposed of properly in compliance
with all environmental regulations . Disposing
of veh icle batteries improperly is very danger­
ous to the environment .

To reduce the risk of lime scale depos its on the
spray nozzles, use clean water with low amounts
of calcium. Always add w indow cleaner to the wa­
ter . When the outside temperat ures are cold , an
anti-freez ing agent shou ld be added to the water
so that it does not freeze. ..,.

Depending on the equipment, the vehicle tool kit
may be located under the spare tire under an ad­
d itional cover or in the too l box. The position of
the vehicle jack* may vary.
A WARNING
Improper use of the vehicle jack can cause se­
r ious personal injuries.
- Never use the screw driver hex head to
t ighten wheel bolts, since the bolts cannot
attain the necessary tighten ing torque if you
use the hex head, potentia lly causing an ac­
c ident.
- The factory-supplied jack is intended on ly
for your vehicle model. Under no circum­
stances should it be used to lift heavy
vehicles or other loads; yo u risk injuring
yo urself.
- Never start the engine whe n the vehicle is
raise d, which could ca use a n accident.
- Support the veh icle secure ly with appropr i­
a te stands if wor k is to be perfo rmed u nder ­
neath the veh icle; otherwise, the re is a po­
tential risk for in jury.
- Never use the jack s upplied with your Audi
on another vehicle, particularly o n a heav ier
one. The jack is only suitab le for use on the
vehicle it came wit h.
