A discharged battery can freeze at temperatures of only O 0C. Allow a
frozen battery to thaw completely before attempting to charge it
~ & .However, we recommend not using a thawed battery again
because the battery casing can be cracked due to ice formation and
can leak battery acid.
Battery charging (Maximum charging rate of 30
amps/14.8 Volt)
When charging at low voltages (e.g. with a trickle charger ), the
battery cables do not have to be disconnected first . The battery caps
sho uld
not be opened when charging a battery.
It is not necessary to remove the battery from the luggage com part·
ment.
Fast charging the battery (charging rate above 14.8
Volts)
For technical reasons do not use a battery charger that uses voltage
greater than 14.8 Volts to charge your vehicle's battery .
& WARNING
Charging a battery can be dangerous.
• Always follow the operating instructions provided by the
battery charger manufacturer when charging your battery.
• Never charge a frozen battery. It may explode because of gas
trapped in the ice. Allow a frozen battery to thaw out first.
• Do not reuse batteries which were frozen. The battery housing
may have cracked and weakened when the battery froze.
• Charge the battery
in a well ventilated area. Keep away from
open flame or electrical spark. Do not smoke. Hydrogen gas gener-
ated by the battery is explosive. •

& 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. •

Tires
General notes
Tires may be the least appreciated and most abused
parts of a motor vehicle.
T ir es may be the least apprec iated and most abused pa rts of a moto r
vehicle. Tires are, however, one of the most important parts of a
veh icle, parti cularly conside ring the comparative ly small patch of
rubber on eac h tire that assu res that all- important co ntact between
you , your ve hicle and the road .
Ma inta in ing t he correct t ire pressu re, making s ure that your veh icle
and i ts tires do not have to carry more weight than they can safely
hand le, avoid ing damage from road ha za rds and reg ula rly inspect ing
tires for damage incl ud ing c uts, s lashes irregular wea r and overall
condi tion are the mos t important th ings that you can do to help avoi d
sudden tire fa ilure includ ing t read separation and blowouts .
Avoiding damage
If you have to drive over a curb or sim ilar obstacle, drive very s lowly
and as close as poss ible at a right angle to the cu rb .
Always keep chemicals including grease, oil , gasoline and bra ke fl uid
o ff the t ires .
Inspect the ti res regularly for damage (cuts, crac ks o r bl ist ers, e tc .).
Remove any foreign bodies embed ded in the trea ds.
Storing tires
M ar k tires when yo u remove t hem to indica te the d irect ion of rota ­
tion . This ens ures yo u to be able to mo unt them co rrectly whe n you
re insta ll them.
Wh en r emoved, t he wheels or tires s hould be sto red in a c ool, dry and
preferably da rk p lace. Sto
re tires in a ver tica l pos it ion if they a re not mounted on rims, in a
hor izonta l position if they are mo unted on r ims.
New tires
N ew tires have to be bro ken in~ & .
Th e tread dep th of new tires may v ary, ac cor ding to t he type an d
make of t ire and the tread pattern.
Hidden damage
Dama ge to t ires and rims is often not readi ly visible . If yo u notice
unusu al v ib rat ion o r the veh icle pulls to one sid e, t his may i ndicate
that one of the tires has been damaged. The tires must be c hecke d
i m medi ately by an a uthor ized A udi deale r or quali fied w or ksh op .
Unidirectional tires
A u nidirectional tire can be identified by arrows on the sidewall, that
point in the d irect io n the tire is des igned to rotate. Yo u m ust follow
t he s peci fied dire ction of ro tation . T his is nece ssary so th at t hese
tires can develop the ir optimum c haracter istics regarding gr ip, road
noise, we ar and hy dropl aning res istance. For more informa tion
~page 344 .
& WARNING
New tires or tires that are old , worn or damaged cannot provide
maximum control and braking ability.
• New tires tend to be slippery and must be broken in. To reduce
the risk of losing control, a collision and serious personal injuries, drive with special care for the first 350 miles (560 km) .
• Driving with worn or damaged tires can lead to loss of control,
sudden tire failure , including a blowout and sudden deflation ,
crashes and serious personal injuries. Have worn or damaged tires
replaced immediately. .,_

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle .
Fig. 239 Tire pre ssure
la bel: loc ate d on
d river 's si de B ·pillar
Tire pressure generally refers to the amount of air in a t ire that it
needs it to do its job and safely carry the combined load of the entire
vehicle and its contents . Tire pressure is measured in kilopascals
(kPa), the inte rnational measur ing un it and in pounds per square i nch
(PSI). Tire press ure is based in part on t he vehicle 's design and load
limit -the greatest amount of weight tha t the vehicle can carry safe ly
and the t ire si ze. The proper tire pressure is frequently referred to as
the "recommended cold t ire inflation pressure. " Air in t he tires
expands when the tire heats up because of internal friction when it
flexes in use . The tire p ress ure is highe r when the t ire has wa rmed up
than when it is "cold." It is the inflation pressure in a "cold" tire that c o unts . Therefo re, you should never let air ou t of a wa rm tire to
match "cold tire inflation pressure " recommendations . The t ires
wou ld then be underin flated and could fail suddenly .

Maintaining proper tire pressure is one of the most important things
you can do to he lp avoid sudden tire failure . Underinflated tires are a
ma jo r cause of sudden tire failure . Keep ing t ires at the right pressure
is a lso important fo r safe and responsive vehicle handling, t ract ion,
braking and load carrying.
Tire p ressures are particularl y important
when the vehicle i s being driven at higher speed s, and then e spe ­
cially when h eavily loaded even with in the permissible load­
carrying capacitie s approved for your v ehicle .
The recommended tire pressures for your Audi depend on the kind o f
t ires on you r vehicle and the number o f passengers and/or amo unt of
luggage you will be transport ing .
The tire pressure label is located on the driver 's side 8-pillar . T he tire
pressure labe l lists the recommended cold t ire inflation p ressures for
the vehicle at its maximum capacity weig ht and tires that were on
