Engine coolant temperature gauge
The engine coo lant gauge ~ page 10, fig . 3 @
only wor ks when the ign ition is on. To prevent
damage to your engi ne, please note t he fo l­
lo wing important points :
Engine cold
As long as the need le rem ains a t the left end
of the gauge, the engine s till has not reac hed
its operating temperat ure. Avoid high engine
speeds, heavy e ngine loads and heavy throt­
tle.
Normal temperature
When the engine has re ache d its ope rat ing
temperature, the need le w ill move into the
mid dle of t he gauge and rema in there .
If the
engine is working hard at high outside tem ­
peratures, the needle may turn fu rther to the
right. This is no cause for concern as long as
the . war ning light i n the inst rument cluster
does not illuminate .
When the. warning light starts to f lash,
th is can mean one of two things: either the
coolant
temperature is too high, o r the coo l­
ant
level is too low ~ page 31 .
A WARNING
--Always obs erv e the warn ing in
~ page 17 2, Engine compar tment be ­
fore opening the eng ine hoo d and check­
ing the eng ine coolan t leve l.
- N ever ope n the eng ine hood if you see or
hea r ste am, or if you see e ngine c oo la nt
dripping from t he en gine compar tment .
You could burn yourse lf . Let the engi ne
coo l off fi rst so that you can not hear or
see any steam or engine coo lant.
(D Note
- M ounting ad ditiona l lights or accessories
in front of the air inlets reduces the coo l­
ing effect of t he radiato r. At high o utside
tempe rat ures or h igh engine load, the
eng ine could overheat.
- The front spoiler has been designed to
properly d istribute the cooling a ir when
the vehicle is movi ng. If the spoiler is
damaged, this could reduce the coo ling
e ff ect a nd the eng ine could then ove r­
heat . As k yo ur au thori zed A udi deal er for

Braking
General information
What affects braking efficiency?
Ope rating condition s and driving h abits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits ¢.&, . On ve ­
hicles that a re either dr iven mostly in stop­
and-go city t raff ic or are dr iven hard, the
brake pads should be chec ked by yo ur author­
ized Audi dea ler mo re often than specified in
the
W arranty & Maintenanc e boo klet. Failure
to have your brake pads inspected can result in reduced brake performance .
On steep slopes, you should use the braking
effect o f the engine . This way, you prevent un ­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down cont in uous ly. Pump the brakes at inter­
vals.
Noises may occur when braking depending on
the speed, braking force and o utside condi­
tions such as temperature and humid ity.
Moisture o r ro ad s alt
U nder certa in conditions, for examp le, when
driving through water or very heavy rain , or
even after washing your vehicle, the b raking
effect can be reduced due to moist ure (or in
freezing cond itions ice) on the brake pads. A
few cautious brake applications should dry off
the brake pads or remove any ice coatings .
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and t he brakes are not used. L ikewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap-
plications of the b rake ¢ .&, .

160 Driving and en vi ro nment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel .
.,. Shut the engine off when you are not dr iving
the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut
off the engine in traffic
jams, when waiting for trains to pass at ra il­
road crossings, or at traff ic l ights that have
l ong wa its on red . Turning the engine
off fo r
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fu lly when it is running at idle . However , wear
and nox ious em issions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high RPMs whi le the engine
is sti ll warming up.
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate imp roper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
Audi dea ler helps to ensure that it runs prop­
erly and economica lly. The cond it ion of yo ur
vehicle not only affects its safety and ability to
hold its value, it also affects fuel consump­
tion .
Check you r oil ea ch time you fill you r tank. T
he amount o f oi l used is re lated to engine
load and speed.
It i s normal fo r the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been d riven.
You must drive your veh icle about 3,000 m iles
(S,000 kilometres) before yo u can properly
assess oil consumpt ion.
T his also app lies to fue l consumption and en­
gine o utput.
(D Note
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Wa rranty
& Main­
t enance boo klet . Lack of p roper ma inte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved
by the manufacturer.
- Do not alter or remove any device, such
as heat sh ie lds, switches, ign it ion w ires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances w ith a
cold engine .
T he engine and cata lytic converter have to
reach their opt imal operat ing temperature to
reduce fuel consumption and nox ious emis­
s ions effectively .
- Ju st after starting, a cold engine in a mid­
size car burns the fue l at a poor rate of 6-8
m iles per gallon (30-40 l/l00km). Half a
m ile down the road , the mileage improves
to 12 MPG (20 l/100 km). It w ill take the

regular basis, fo r example when
refuelling your vehicle.
- Never use a dry cloth or sponge to clean
the headlights . Only use wet cloths or
sponges to prevent scratches. It is best
to use soapy water.
@J For the sake of the environment
In the interest of the env ironment, the ve ­
hicle sho uld only be washed in special
wash bays.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you observe a few simple rules .
.. Before us ing the power washer, make sure
you have read and understood the WARN­ INGS
c> & in General information on
page 162.
.. Always fo llow the operating instructions for
the power washer .
.. Make sure that the jet on the spray hose pro ­
duces a "fan shaped spray".
.. Do
not hold the spray nozzle too close to
soft materia ls.
N eve r u se a pow er w asher to clean the power
top itse lf.
When clea ning t he vehicle w it h a powe r wash­
e r
always fo llow the operating instructions.
This applies particularly to the
o pera tin g
p re ssu re
and the s p ra yi ng dist ance. Maintain
a sufficient distance to soft materials such as
rubber hoses and so und/vibration deadening
materia ls (part icularly on the underside of the
engine hood). Do not use a jet wh ich sprays
water in a
dire ct st ream or one that has a ro ­
tat ing
jet .
Water temperature shou ld not exceed 140 °F
(60
°() .
A WARNING
Never wash tires w ith a jet that sprays wa ­
ter in a d irect stream. This could cause in- visible damage to the tires and weaken
them, even
if the spray is from a relative ly
long distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal inju ry.
(D Note
- Never use a power washer to clean the
power top itself.
- To avoid damaging your veh icle, always
make sure that there is sufficient dis­
tance between the spray head and soft
materials like rubber hoses, plast ic parts
and sound-deadening materials. Never
aim the spray head at the same point for
a long time. This also app lies to cleaning
head lights and pa inted b umpe rs. Re­
member: the closer the nozz le is to the
surface of the material, the greate r the
stress on the materia l.
Convertible top care
The convertible top requires special care.
Keeping you r top looking great and mak ing
certain tha t it lasts a long time depend to a
great extent on proper use and care . Remove
bird droppings as soon as possible, since the
corrosive chemicals in them will cause the
rubber impregnation in your top to swell and
poss ibly allow the fabric to leak .
With
normal soiling, all you need to do is
clea r the top with a soft br ush and clear wa­
ter. A lways brush in the direction of the fabric
from front to rear.
If the top is very dirty and has spotted areas
clean it with a brush using a convertible top
cleaner . Always brush in the direction of the
fabric from front to rear. R inse with plenty of
clear water, and allow the top to air-dry.
Chamois are not suitable for drying the top.
Never use gaso line, spot remover, benzene,
paint thinner or solvents to remove spots . We
recommend that you on ly use cleaners espe­
cia lly formulated for use on convertib le tops,
and that you fo llow the produce use directions ...

-Apply the parking brake.
- Move selector lever to "P" (Park).
- Always let the engine cool down. Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment. Wa it until no steam or
coolant can be seen or heard before care­
fully 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 .
- 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 to "P" (Park).
Checking and filling 179
-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 wear no clothing that will
hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards
