2014 AUDI A7 engine

cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec­
trical spark. Do not smoke. Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe­
tent technician with the proper equip ­
ment .
- Battery acid that may spill during charg­
ing should be washed off with a solution
of warm water and baking soda to neu­
tralize the acid.
0 Note
Never use a fast charger as a booster to
start the engine . This will seriously dam ­
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi­
cations and dimensions as the original equip­
ment battery.
Intelligent energy management in your vehi­
cle is responsible for distributing the electri­
cal energy throughout your vehicle
q page 202. The intelligent energy manage­
ment system will keep the engine battery
charged better than vehicles without this sys­
tem. To make sure the additional electrical en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries of the same type and manu ­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery housing. Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor­ rectly after replacing the battery.
Checking and filling 241
The new battery must have the same capacity,
voltage (12-volts), amperage, construction and plug sealing.
When installing the battery, make sure the ig ­
nition and all electrical consumers are switch­
ed off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out.
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi­
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author­
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and lead and must always be disposed of prop­
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi­
ronment.
