-To reduce the r isk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before ca re­
fully opening the hood .
- Keep children away from the engine com ­
partment.
- Never spill flu ids on hot engine compo­
nents. They can cause a fire .
- Never touch the radiator fan. The aux ili­
ary e lectr ic fan is temperature controlled
and can switch on suddenly .
- Never open the coolant reservoir cap
when the eng ine is still warm . The cool­
ant system is pressur ized and hot coo l­
ant could spray out.
- Protect your face, hands and arm from
steam or hot eng ine coolant by placing a
thic k rag over the cap when you open the
coolant reservoir.
- Do not remove the engine cover under
any c ircumstances. Th is increases the
risk of bu rns.
- If wo rk on the fuel system or the electri­
cal sys tem is ne cessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames . Fluids in the engine com­
partment co uld start a fire.
- Keep an approved fire extinguisher im­
mediately ava ilable.
- To avoid electrical s hock and persona l in­

transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewe lry, or long hair from get­
ting caught in the radiator fan, V-be lts
or other moving parts, or from contact­ i ng hot parts . Tie back hair before
starting, and do not wear clothing that
will hang o r droop into the engine .
- Minimize exposure to emission and
chemical hazards~&. .
A WARNING
California Proposition 65 Warning:
- Engine exhaust, some of its const ituents,
a nd certain vehicle components contain
or emit chemicals known to the State of
Ca lifornia to cause cance r and birth de­
fects and reproductive harm. In addition, certain fl uids contained in veh icles and
certain products of component wear con­
tain or emit chemica ls known to the
State of California to cause cancer and
birth defects or other reproductive harm.
- Battery posts, terminals and related ac­
cessories conta in lead and lead com­
pounds, chemicals known to the State of
California to cause cancer and reproduc­
tive harms. Wash hands afte r handling.
Q) Note
When adding f lu ids, always make sure that
they are poured into the proper conta iner
or f iller opening, otherwise serious dam­
age to vehicle systems w ill occur .
@ For the sake of the environment
To detect leaks in time, inspect the vehicle
floor pan from underneath regular ly . If
you see spots from oil or other veh icle flu­
i ds, have your vehicle inspected by an au­
thorized Audi dealer. •
•

-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 de­
signed for the conditions
that are typical in those sea­
sons. Audi recommends us­ing winter tires during the
winter months. Low tem­ peratures significantly de­
crease the elasticity of
summer tires, which affects
traction and braking ability.
Tires and wheels 229
If summer tires are used in
very cold temperatures, cracks can form on the tread bars, resulting in perma­
nent tire damage that can
cause loud driving noise and unbalanced tires. Audi is not
responsible for this type of
damage.
-Burnished, polished or chromed rims must not be used in winter road condi­
tions. The surface of the
rims does not have suffi­
cient corrosion protection
for this and could be perma­
nently damaged by road salt
or similar substances.

steering, power brakes, power
windows, power seats, radio, and heater, to the extent that
these items are available as fac­
tory-installed equipment (whether installed or not).
Aspect ratio
means the ratio of the height to
the width of the tire in percent. Numbers of 55 or lower indi­
cate a low sidewall for im­ proved steering response and
better overall handling on dry
pavement.

Bulbs
Replacing bulbs
For your safety, we recommend that you hove
your authorized Audi dealer replace any bulbs
for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since 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 metal and bulb holders can have sharp
edges that can cause serious cuts, parts must
be correctly taken apart and then properly put
back together to help prevent breakage of
parts and long term damage from water that
can enter housings that have not been p roper­
l y resea led.
For your safety, we recommend that you have
you r authorized Aud i dea ler replace any bulbs
for you, since yo ur dealer has the proper too ls,
the correct bulbs and the expertise .
Gas discharge lamp s (Xenon lights)*:
Due to the high electr ical voltage, have the
bulbs replaced by a qualif ied techn ic ian.
Headlights wit h Xenon light are identified by
the high voltage sticker.
_&. WARNING
Changing Xenon lamps witho ut the neces­
sa ry equipment can cause serious persona l
injury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
