particular require a great deal of energy. If
you notice, for example, that the heated seats* or the heated rear window are not
heating, they have been temporarily cut back
or switched off. These systems will be availa ble again as soon as the energy balance has
been restored.
You will also notice that engine idle speed has been increased slightly. This is normal and not
a cause for concern . By increasing engine idle
speed the additional energy required is gener
ated and the battery is charged.

_& WARNING
The temperature o f the exhaust system is
high, both when driving and after stopping
the engine .
- Never touch the exha ust tail p ipes once
they have become hot. This could result in burns .
- Do not park or operate the veh icle in
areas where the hot exhaust system may
come in contact with dry grass, brush,
fuel spill or other material which can cause a fire .
- Do not apply additional undercoating or
rustproofing on or near the exhaust
man ifold , exhaust p ipes, catalytic con
verte r or heat shie lds. D uri ng d riving, the
substance used for undercoating cou ld
over heat and cause a fire .
(I) Note
- Be aware that just one tank filling with
l eaded fuel will already seriously de
grade the perfo rmance of the cata lytic
conve rter.
- Do not exceed the correct engine oil leve l
¢page 215.
- Do not d rive until the fuel tank becomes
completely empty. The eng ine could mis
fire. Unburned f uel could a lso ge t in to
t h e exhaus t sys tem and this could cause
the ca talyt ic converte r to ove rheat.
- Do no t switch off the ign ition wh ile the
vehicle is moving.
- Do no t continue to operate yo ur vehicle
u nder these condi tions, as otherw ise fuel
can reac h the catalytic converter . This
could result in overheating of the co n
verter, req uiring its replacement.
- To assure efficient operation of the Emis
sion Control System :
- Have your veh icle maintained properly
and in accordance with the service rec
ommendations in your Wa rranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir the function of the em
ission cont ro l
system and could lead to damage .
~ For the sake of the env ironment
Even when the Emiss ion Con trol Sys tem is
operat ing proper ly, the exha ust gas can
have a sulfur-li ke ex haust gas smell under
some ope rat ing states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or fil ling the tank with lead -free super
grade gasoline .
Shutting down vehicle
If you would like you r vehicle to remain inop
erative for a longer per iod of t ime, contact an
Audi o r other spec ia lized dealer. They can ad
v ise you on ne cessa ry precautions e .g. co rro
s io n preven tion , maintena nce and s to rage.
Pay a ttent ion to addi tional in fo rmat ion con

Operate your vehicle
economically and
minimize pollution
General
Your p ersonal style of driving will determine
the economy of your vehicle , as well as ex
haust and nois e le ve ls .
Fu el economy, environmenta l impact, and
wear on your engine , brakes and tires largely
depend on three factors:
- your personal d riving style
- operati ng conditions
- technical limitat ions
If you an tic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt io n by 10 -15 percent . This sec
t ion w ill give you some tips on how you can
help the e nvir onment and your pocketbook .

212 Check ing and filling
- 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 persona l 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 repa ir
with the engine running:
- Fi rst, fully apply the parking bra ke,
move se lec to r lever to P (Pa rk) .
- Always use extreme caution to preven t
clot hing, jewe lry, or long h air from ge t
ting caught in the radiator fan, V -belts
or other moving parts, or from contact ing hot parts. Tie back hair before
start ing, and do not wear cloth ing that
will hang or droop into the eng ine.
- Min imize exposure to emission and
chemica l hazards¢ ,&..
A WARNING

Battery
General information
Under normal operating conditions, the bat
tery in your Audi does not need any mainte
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by a service fa
cility . The electrolyte level shou ld also be
checked each time the battery is charged
¢ page 223.
Have the battery checked when you take your
ve hicle in for service . You are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec

Disconnecting the battery terminals
Some vehicle functions (power w indow regu
lators , for example) are lost if the battery ter
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .
Vehicles not driven for long periods
If you do not drive you r vehicle over a period
of severa l days or weeks, elec trical compo

also last longer .
@ Tips
If your vehicle is left standing for seve ral
weeks at extremely low temperatures, the
vehicle battery s hou ld be removed and
stored where it will not freez e. This will
p reve nt it from be ing dam aged and having
to be repl aced .
Working on the battery
Be especially careful when working on or near
the bat tery.
The battery is located in the luggage compar t

A WARNING
Whenever working on the battery or on
the electrical system, there is the r isk 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 contai ns 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 your eyes or
on your sk in, immediately rinse with
cold water for severa l m inutes 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 injury. -
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
must 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 connect the pos it ive cable 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
(0 oc).
- 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.
