Engine compartment
Be especially careful when cleaning the engine compa rt­
men t.
Always switch off the ignition before cleaning the engine=:>& .
Plenum panel
Remove leaves from the plenum panel in front of the win dshi eld
unde r th e eng ine hood . T hi s prevents the water d rain holes from
becoming b locked, and it prevents debris from entering the vehicle
inter io r th rough the heat ing and vent ilation ducts .
Corrosion protection
The eng ine compartment and transmission have been cor rosion­
protected at the factory.
Good ant i-cor rosion treatment is very impo rtant , pa rtic ular ly in the
w inter . If the vehicle is frequently driven on sa lt treated roads, the
en tire eng ine compar tment and plenum p anel sho uld be thoroug hly
cleaned at the end of winter and retreated to prevent salt damage. At
t he same t ime, the underside of the vehi cle should be washed as well.
If the e ng ine compartment is clea ned at any t ime with grease
removing so lutions
2l , or i f you have the engine washed , the anti ­
co rros io n treatment is a lmost a lways removed as w ell.
It is t herefore
essential to have a long-last ing corrosion p rotect ion reapplied to all
surfa ces, seams, jo ints and compo nents in the engi ne co mpa rt ment .

Engine cooling system
Coolant
The e ngine co o la nt per form s two functio ns: it keeps the
engine from ove rh eati ng and it protects t he engine from
free zing in the winter .
The cooling system is sealed an d genera lly req uir es little attention. The cooling system has been f
illed at the factory wit h a permanent
c oo lant whi ch does no t need to be c hanged . Th e coolan t cons ists o f a
mixt ure of water and the manufacturer's glycol-basedcoolant addi ­
tive G12+ + antifreeze with anticorrosion ad dit ives (50% for USA
mode ls; 60% for Ca nadian models) . This mixture both ass ures the
necessary frost protection and protects meta l components in the
eng ine's cooling system from co rrosion and scaling. It also raise s the
boiling point of the coo lant .
Do not re du ce the co ncent ration of the coo lant in the summer by
add ing p la in water .
The proportion of coolant add itive must be at
least 50% but not more than 60%
to mai ntain an tifreeze pro tection
and coo ling efficiency . If the coolant frost p rotect io n i s too low, the
coo lant co uld freeze an d damage t he veh icle heating and engine
coo ling system .
For year-round driving, antifree ze is added at the factory for temper­
a tures dow n to:
• -31°F(-35°C)USA
• - 4 0 °F ( -40 °C) Canad a.
You can mix the G12 ++ coo lant addit ive w ith other additives (G12+ or
G 12). A lways check with yo ur autho rize d Audi dea ler.
& WARNING
Before you che ck anything in the engine compartment, always
read and heed all WARNINGS~

& WARNING (continued)
• 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 competent technician with the proper equipment.
• Battery acid that may spill during charging should be washed
off with a solution of warm water and baking soda to neutralize
the acid.
0 Note
Never use a fast charger as a booster to start the engine. This will seri­
ously damage sens it ive electronic components, such as control units,
relays, radio, etc ., as well as the battery charger.•
Battery replacement
The new battery must have the same specifications and
dimensions as the original equipment battery.
Intelligent energy management in your veh icle is responsible for
distributing the electrical energy throughout your vehicle
~ page 259. T he intelligent energy management system will keep
the engine battery charged better then vehicles without this system .
To make sure the additional electrical energy is available once again
after you have changed the battery, we recommend that you install
batteries of the same type and manufacture only (the same as those
installed at the time your vehicle was delivered). Specifications are
listed on the battery housing. Your authorized Audi dealer will then
code the battery management control unit.
If it is not poss ible to use a battery of this type, the new battery must
have the same capacity, vo ltage (12 volts), amperage, construction
and plug sea ling .
When installing the battery, make sure the ignition and all electrica l
consumers are turned off.
0 Note
Make sure the vent ilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
Because of the problem of proper disposal of a battery, we recom­
mend your authorized Audi dealer change the battery for you.
Batteries contain sulfuric acid and lead and must always be disposed
of properly in compliance with all environmental regulat ions.
Disposing of vehicle batteries improperly is very dangerous to the
environment. •
