coolant can be seen or heard before
carefully opening the hood.
- Keep children away from the engine com­
partment.
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­ ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­
ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery .
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running:
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park) .
-Always use extreme caution to prevent
clothing, jewelry, or long hair from get- ting caught in the
radiator fan, V-belts
or other moving parts, or from contact­
ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine .
- Minimize exposure to emission and
chemical hazards

A WARNING
-California Proposition 65 Warning:
- Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth de­
fects and reproductive harm. In addition,
certain fluids contained in vehicles and
certain products of component wear con­
tain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories contain lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands after handling.
(D Note
When adding fluids, always make sure that
they are poured into the proper container
or filler opening, otherwise serious dam­
age to vehicle systems will occur.
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regularly. If
you see spots from oil or other vehicle flu­
ids, have your vehicle inspected by an au­
thorized Audi dealer.

196 Tire s and wheel s
-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden t ire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age.
(D Note
- Please note that summer and winter
tires are designed for the cond itions that
a re typ ica l in those seasons. Aud i recom-
Glossary of tire and loading terminology
Accessory weight
means t he comb ined we ight (in excess of
those sta ndard items wh ich may be rep lace d)
of automa tic transmission, power s teering ,
power brakes, power wi ndows, power seats,
radio, and heater, to the extent that thes e
items are availab le as factory-installed equip­
ment (whether ins talled or not) .
Aspect ratio
means the ratio o f the height to the width of
the tire in percent. Numbers of 55 or lower in ­
d icate a low sidewall for improved steer ing re ­
sponse and better overall handling on dry
pavement.
Bead
means t he pa rt of the tire that is made of
steel wires, wrapped or reinforced by ply cords
and that is shaped to fit the rim .
Bead separat ion
means a b reakdown of the bond between
components in the bead.
Cord
means the strands forming the plies in the
tire. mends using winter tires during the w
in ­
ter months. Low temperatures signifi­
cantly decrease the elastic ity o f summe r
tires, which affects traction and braking ability . If summer tires are used in very
co ld temperatures, cracks ca n form o n
the tread bars, resu lting in permanent
tire damage that can cause lo ud driving
noise and unbalanced tires. Aud i is no t
responsib le for this type of d amage .
- Burn ished , polished or chromed rims
must not be used in winter road condi ­
tions. The s urface of the rims does not
have s uff ic ient corrosion protection for
this and could be permanently damaged
by road sa lt o r similar substances .
Cold tire inflation pressure
means the t ire p ress ure recommended by the
vehicle m anufacture r fo r a tire o f a des ign ated
s ize that has not been d riven for more than a
coup le of miles (ki lometers) at low speeds in
the three hour period before the tire p ress ure
is measured or adjusted .
Curb weight
means the we ight of a motor ve hicl e w ith
standard equipment including the maximum
capac ity of fuel, oi l, and coolant, air condi­
tion ing and additional weig ht o f optiona l
equipment.
E x tra load tire
means a t ire design to operate at higher loads
and at higher inflation pressures than the cor ­
responding standa rd tire . Extra load tires may
be identified as "XL", "x l" , "E X TRA LOAD", or
"RF" on the sidewall.
Gross Axle Weight Rating ("GAWR ")
means the load-carrying capa city of a s ingle
axle system, measured at the tire-ground in-
terfaces.

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increas ingly more and more
difficult to replace vehicle lig ht bulbs s ince in
many cases, other parts of the car must first
be removed before you are able to get to the bulb.
This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet meta l and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correct ly taken apart and then properly put
back together to he lp prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper­
ly resealed.
For your safety, we recommend that you have
your authori zed Audi dea ler replace any bulbs
for you, since your dealer has the proper tools,
the correct bulbs and the expertise.
Gas discharge lamps (Xenon lights ):
Due to the high e lectr ica l voltage, have the
bulbs replaced by a qualified technician.
Headlights with Xenon light are identified by
the high voltage st icker.
A WARNING "--
Changing Xenon lamps without the neces-
sary equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On veh icles equipped with gas discharge
bulbs (Xenon light) life-threatening inju­
ries can result from improper handling of
the high-voltage portions of such lamps!
- Only your authorized Audi dealer or qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an authorized Audi dealer or qualified
workshop. Serious personal injury may
result from improperly performed work.
@ Tips
-If you still prefer to replace the light
bulbs yourself, be aware that the engine ..,.
