A WARNING
Whenever working on the battery or on
the electrical system, there is the risk of
injury , acc ident and even fire. Read and
heed the following WARNINGS:
-Always wear eye protection. Do not let battery acid or any lead part icles get on
your sk in or cloth ing . Sh ield your eyes .
Explosive gases can cause blindness or
other injury .
- Battery acid contains sulfur ic acid . Sulfu­
ric acid can cause blindness and severe
burns.
- Always wear gloves and eye protection.
Do not tilt the battery because ac id
could leak out of the vent ilation open­
ings.
- If you get battery acid in yo ur eyes or
on your sk in, immediately rinse with
cold water for severa l minutes and get
medical attention .
- If you should ingest any battery acid,
seek medical attention immediately.
- Do not expose the battery to an open
flame, electric sparks or an open light.
- Do not smoke.
- Do not interchange the positive and neg -
ative cab les.
- When working on the battery, be sure
not to short-circuit the terminals with
tools or other metal objects. This would
cause the battery to heat up very quickly,
wh ich could lead to damage or explosion
and personal in jury.
-
- When a battery is charged, it produces
hydrogen gas which is explosive and
could cause personal injury.
- Always keep the battery well out of the
reach of children.
- Before work is done on the electrical sys­
tem, disconnect the negat ive ground ca­
ble.
- Before performing any work on the e lec­
trica l system, switch off the engine and
ignit ion as well as any electrical equip­
ment. The negative cable on the battery
m ust be disconnected .
If you are just go­
ing to replace a light bulb, then it is
e nough to swi tc h off the lights.
- Before disconnecting the battery, switch
off the anti-theft alarm system! Other­
wise you wi ll set off the alarm.
- When disconnecting the battery, f irst
d isconnect the negat ive cab le and then
the posit ive c ab le.
- Before reconnecting the batte ry, ma ke
sure all e lectr ica l consumers are sw itch­
ed off . Re conne ct the pos it ive cab le first
and then the negative cable. Never inter ­
change the cables - this could start a fire!
- Never charge a frozen or a thawed-out
battery. It could exp lode! If a battery has
frozen, then it must be replaced . A dis­
charged battery can freeze over at 32°F
(QOC).
- Make sure the vent hose is always attach­
ed to the opening on the s ide of the bat­
tery.
- Never use batteries which are damaged.
There is the danger of an explosion! Al­
ways rep lace a damaged battery.
A WARNING
Ca lifornia Proposition 65 Warning:
- Battery posts, terminals and related ac­
cessories conta in lead and lead com­
pounds, chem icals known to the State of
California to cause cancer and reproduc­
tive problems . Wash hands after han-
dling.
~

228 Check ing and filling
- To r educe the danger of explosion, never
co nnect or disconn ect cha rger cables
wh ile the c harger is operating.
- Fast char ging a battery is dangerous and
shou ld on ly be attempted by a compe­
tent technician w ith 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.
(Q) 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, rad io, etc., as we ll
as the battery charger.
Battery replacement
The new battery must have the same specif/·
cations and dimensions as the original equip­
ment battery.
Intell igent energy management in your veh i­
cle is respons ible for d istributing the e lectr i­
cal energy throughout you r vehicle
~ page 193. The intell igen t energy m anage­
men t system w ill keep the engine ba tte ry
charged better then vehicles w ithout this sys­
tem . To make sure the additional e lectrica l en­
ergy is available once again after you have
changed the battery, we recommend that you install batteries o f the same type and ma nu­
facture only (the same as those installed at
the time your vehicle was delivered). Specifi­
cations are listed on the battery hous ing. Your
author ized Audi dealer must code the battery
in the ene rgy management system to enable
you to use the ene rgy management functions
correctly after replac ing the battery.
I f it is not poss ible to use a battery of this
type, the new bat tery m ust h ave the s ame ca­
pac ity, voltage ( 12-volts), amperage, con ­
struction and plug sea ling. When installing the battery, make su
re the ig ­
nition and a ll electrical consumers are turned
off.
(D Note
Make sure the ventilation hose on the side
of the battery is connected, otherwise
fumes or battery acid can leak out .
@ For the sake of the environment
Because o f the p rob lem of p roper disposal
of a battery, we recommend your author ­
i zed Audi dealer change the battery for
you. Batteries contain sulfur ic acid and
l ead and must always be disposed of prop­
erly in comp liance with all environmental
regulations. Dispos ing of veh icle batter ies
i mprope rly is very dange rous to the envi­
r o nment .

-Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowout and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­ lar .
The recommended t ire pressures are on the
tire pressure label and in the table
c:> page 234, Cold tire inflation pressure . This
means that the pressure must be checked and
adjusted when the tire has not been driven for
mo re tha n a couple of m iles (k ilome ters) at
l ow speeds during t he p revious three hours.
A ir in the tires expands when the ti re heats up
as a result of inte rna l friction as it flexes in
use. The tire press ure is higher when the tire
has warmed up than when it is "cold."
It is the i nflat ion p ressu re in a "cold" tire that
counts . Therefore, you shou ld never let air ou t
of a warm tire to match "Cold tire inflation pressure" recommendations
c:> page 234. The
tires would then be under inflated and could
fa il suddenly.
The tire press ure labe l on yo ur Audi lists the
recommended cold t ire inflat ion pressures at
maximum capacity for the new, origina l
equ ipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the label
<=> page 234, fig . 189 .
Most tires lose a ir naturally over time. They
can also lose some a ir if you drive
over a pot­
hole or hit a curb while parking. It is usually
not possible to see whether the radial t ires
used today are underi nflated just by looking
at them.
Therefore, be sure to check tire pressures at
least o nce a month and always before going
on a long tr ip . Make sure to take the number
of people and the amount of luggage into ac­
coun t when adjusting tire pressure for a t rip -
even one that you would not consider to be
Tire s an d wheel s 237
"long." See c:> page 2 38, Tires and vehicle
load limits
for more important information.
A lways use an acc ura te tire pressu re ga uge
when checking and ad justing infla tion pres ­
s ur es . Check all o f the tires and be sure not to
forget the spare tire. If the pressure in any t ire
is too h igh when the tire is "cold", let a ir o ut
of the t ire s low ly w ith the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the load (passengers and luggage) and k ind of
driv ing you plan to do.
If the pressure in any tire is too low, note the
difference between the pressure in the co ld
t ire a nd the pressure you need and add the air
that you need to reach the correct pressure for
t h e ve hicl e load (passenge rs and luggage) for
the tires on you r veh icle as l isted on the on
yo ur vehicle and in this ma nual and the kind
of driving you plan to do.
Never exc eed the maximum inflation pr es­
sure li ste d on the tire sidewall for any re a­
s o n.
Remember that the vehicl e manufacture r, not
t h e tire manufact urer, de termines t he cor re ct
t ir e p ress ure fo r th e tires on your ve hicl e.
It is important to check the t ire p ressu re whe n
the tires are co ld.
- Read the required tire pressure from the t ire
pressure labe l. The t ire pressure label is lo­
cated o n the dr iver's side 8-pillar. The tire
pressure labe l lists the recommended co ld
tire infla tion pressures for t he vehi cle at its
maxim um capacity weigh t and t he tires that
were on your ve hicle a t the time i t was man­
ufactured . For recommende d tire pressures
for normal load conditions, p lease see chap­
ter
c:> page 2 34.
- Tu rn the va lve stem cap counter -clockwise
to remove it from the tire
va lve .
-Place t he ai r pressure gauge on the va lve.
- The tire pressu res should o nly be checked
and ad justed when the tires are co ld . The
slightly raised pressures of warm tires must
not be red uced.

have the ma lfunction corrected.
A WARNING
- If the tire pressure indicator appears in
the instrument cl uster d isplay, one or
more of your tires is s ignificantly under­
inflated. Reduce your speed immediately
and avoid any hard steering or braki ng
maneuvers. Stop as soon as possible and
check the t ires and the ir pressures. In­
flate the tire pres sure to the proper p res­
s u re as in dic ated on the vehicle 's t ire
pressure label¢
page 234 . Driving on a
significantly under-inf lated tire ca uses the tire to overheat and can
lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly .
- Under certain conditions (such as a spor­
ty driving style, winter conditions or un­ paved roads), the pressure monitor indi ­
cato r may be delayed .
-Ask your authorized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
Your vehicle registration becomes invalid
if you use these t ires when not perm it­
ted. Damage to your vehicle or accidents
could a lso result.
(D Tips
- The tire pressure mon itoring system
stops work ing whe n there is an ESC/ABS
m alfu nction.
- Us ing snow chains may result in a system
ma lf u nction.
- The tire pressure mon itoring system on
your Audi was deve loped using tires with

There is exactly one location for each wheel.
The jack must not be positioned at any other location
c:> ,&. c:>(D .
Soft ground under the jack can cause the ve­
hicle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if necessary . Use a non-slip surface such as a
rubber mat on a
slipp ery surfac e such as tile .
A WARNING
-You or your passengers could be injured
wh ile chang ing a wheel if you do not fol­
low these safety precautions :
- Position the vehicle jack only at the
des ignated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an injury if it does not
have sufficient hold on the veh icle .
- A soft or unstable surface under the
jack may cause the veh icle to slip off
the jack . A lways provide a firm base for
the jack on the ground.
If necessary,
use a sturdy board under the jac k.
- On hard, slippery surface (such as tiles)
use a rubber mat or similar to preven t
the jack from s lipping.
- T o help p revent injury to yourself and
yo ur passengers: -
Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.
- Make sure that passengers wait in a
safe place away from the veh icle and
well away from the road and traffic .
- Make sure jack pos ition is correct, ad­
j ust as necessary and then cont inue to
raise the jack.
(D Note
Do not lift the vehicle by the sill. Position
the veh icle jack only at the designated lift­
i ng points on the sill. Otherwise, your vehi­
cle will be damaged.
