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 .

Battery
General information
Unde r normal operating conditions, the bat ­
tery in your A udi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the elect ro lyte level checked by an authorized
Aud i dea ler o r qualified workshop . The elec­
trolyte leve l sho uld a lso be c hecked each t ime
the battery is c harged
c::> page 192.
H ave the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a bat tery that is older tha n 5 yea rs .
W ith certa in types of a irbag deployment, t he
battery is d isconnected from the vehicle elec­
tr ica l system fo r safety reasons
c::> & in Re ­
pair, core and disposal of the airbags on
page 126.
Disconnecting the battery terminals
Some veh icle functions (power w indow regu­
lato rs, for example) are lost if the battery ter­
m inals a re discon nected. These functions have
to be re lea rned after the batte ry terminals a re
c onnec ted agai n. T o prevent this, the battery
should o nly be di sconnec ted from the vehicle
e lec trica l syste m when absolu tely necess ary
for repairs.
Vehicles not driven for long periods
I f yo u do not dr ive you r vehicle over a pe riod
of severa l days or weeks, elec trical co m po­
n en ts are gr adually cu t back o r swi tched off .

Winter operation
During the w inte r mon th s, batt ery c apac ity
tends to dec rease as tempera tures drop . This
is beca use more power is a lso consumed w hile
starting, and the headlights, rear win dow de­
f ogger, etc., are used more often.
Avoid unnecessa ry powe r consumpt ion, pa r­
ticu lar ly in ci ty traffic o r when traveling only
sho rt distances . Let yo ur autho rized A udi
dealer check the capacity of the vehicle bat ­
tery before w inter sets in

charged battery will not on ly prevent starting
problems when the weather is cold, but w ill
also last longer .
@ Tips
If your vehicle is left standing for seve ral
w eeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
