Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new
b rake pads do not possess their fu ll braking
effect , they have to be "broken in" first¢.&. .
You can compensate for this slightly reduced braking power by push ing harder on the brake
pedal. Avoid heavy braking loads during the
break-in per iod.
Operating condition s and d riv ing hab it s
The brakes on today's automob iles are st ill
subject to wea r, depending largely on operat­
ing conditions and driving habits¢.&. . On
vehicles that are e ither driven mostly in stop­
and-go city traffic or are driven hard, the b rake pads should be checked by your author­
ized Audi dealer more often than specified in
the
Warranty & Maint enan ce booklet . Failure
to have your b rake pads inspected can res ult
in red uced brake pe rformance.
On steep slopes, you shou ld use the brak ing
effect of the engine. This way, you p revent un­
necessa ry wear on the brake system. If yo u
must use yo ur brakes, do not hol d the brakes
down continuously. P ump the brakes at inter ­
va ls.
Operating noise
Noises may occur when braking depending on
the speed, brak ing fo rce and outside condi­
tions such as temperature and humidity.
Effect of water and road salt
In ce rtain situat ions, for example after driving
through water , in heavy ra in, after overn ight
conde nsation or afte r washing your car, the
b rak ing effect can be redu ced by mois ture or
ice on the brake rotors and brake pads . The
brakes must be dried first with a few careful
brake applications .
A t higher speeds and with the w indshield w ip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time .
This occurs at regular intervals witho ut the driver noticing and p
rovides fo r bette r brake
response time under wet conditions .
T he effec tiveness of the brakes can be red uced
when the vehicle is d riven on a sa lt -covered
r oad and the brakes are not used . Likewise,
you clean off accumulated salt coating from brake d iscs and pads with a few cautio us ap­
plicat ions of the brake ¢ .&. .
Corro sio n
The re may be a tendency for di rt to b uild up
on the brake pads and corrosion to form on
the discs if the car is not driven regularly or only fo r short trips w ith litt le use of the
brakes.
If the brakes are not used frequently, o r if cor ­
rosion has formed on the discs, it is advisable
to clean off the pads and d iscs by braking
firmly a few times from a moderately high
speed ¢.&. .
Fault s in the brak e syst e m
If you s hou ld notice a sudden increase i n
brake pedal trave l, then one of the two brake
c ircuits may have failed ¢.&. .
Low brake fluid level
Malfunctions can occ ur in the b ra ke system if
the brake fluid level is too low. The brake fluid
l evel is monitored electronica lly.
Brake booster
T he bra ke booster inc reases the pressure that
you generate wi th the b rake peda l. It works
o n ly when the engine is runn ing .¢ .&.
Brake lining wear status
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
th rough the ope nings in the wheel. If neces­
sary, the wheel may be removed for t his in­
spect ion ¢
page 253, Changing a wheel.
_& WARNING ,____
-New b rake pads don't have the best stop­
p ing power and m ust be "broken-in" dur-
ing the initial 100 to 150 miles (150 to
11>-

194 Driving and en vironm ent
8_ WARNING
After driving through water, mud, slush,
etc ., the brakes may be slow to take effect
because of wet brake rotors and pads. Dry
the brakes first by braking carefully to re­
store the full braking effect.
CD Note
Vehicle components such as the engine,
transmiss ion, suspension or electrical sys­
tem can be severely damaged by driving
through wate r.
@ Tips
- Check the depth of the water before dr iv­
i ng through it.
- Do not stop the veh icle, dr ive in reverse
or switc h the engine off when driving
t hr ough water.
- Keep in mind that oncoming vehicles
may c reate waves that raise the water
l evel and make it too deep fo r you r vehi­
cle to dr ive through safely.
-
- Avoid dr iving thro ugh salt water because
i t can ca use corrosion.
Catalytic converter
It is very important that your emission con­
trol system (catalytic converter) is function ­
ing properly to ensure that your vehicle is run­
ning in on environmentally sound manner.
,,. Always use lead-free gasoli ne¢ page 211,
Fuel supply .
,,. Never run the tank down a ll the way to
empty.
,,. Never put too much motor oil in your en-
gine ¢
page 221, "t':::r. Adding engine oil.
,,. Never t ry to push- o r tow-start your veh icle.
The catalytic converter is an effic ient "clean­
up" device built into the exhaust system of
the vehicle. The catalytic converter burns
many of the polluta nts in the exhaust gas be­
fore they are released into the atmosphe re. The exclusive
use of unleaded f uel is critica lly
important for the life of the catalytic convert­
er and proper funct ion ing of the eng ine .
A WARNING
= -
-Do not park or operate the vehicle in
areas where the hot exhaust system may
come in co ntact with dry grass, brush,
fuel spill or other material wh ich can
cause a fire .
- Do not app ly additional undercoating or
r u stp roofing on or nea r the exhaust
manifold, exhaust pipes, cataly tic con­
ver ter or heat shields. Dur ing driv ing, the
substance used for under coa ting co uld
overhea t and cause a fire.
CD Note
- Be aware that just o ne tank filling with
leaded fu el w ill already ser io usly de ­
gr ad e the per form ance o f the catalytic
c onverte r.
- Do not ex ceed t he corre ct engine oil level
r:;!) page 2 21.
- Do not drive until the fuel tank be co m es
completely emp ty. The engine co uld mis­
fire . Unburned fuel could also get in to
the exhaust system and this co uld cause
the cata lytic converter to overheat .
- Do not turn off the igni tion whi le the ve ­
hicle is mov ing.
- Do not contin ue to ope rate your veh icle
unde r these conditions, as otherwise fuel
can reach the catalyt ic converte r. T his
co uld resu lt in overheating of the con­
verter, requir ing its replacement.
- To assure efficient operation of the Emis ­
sion Control System:
- H ave you r vehicle maintained p rope rly
and in accordance w ith the se rvi ce rec ­
ommen dat ions in yo ur Warranty &
M ain tenance boo klet.
- L ack of prope r maintenan ce as we ll as
i mprope r use of t he ve hicl e wi ll impair
the func tion of the em ission cont ro l
system and could lea d to damage .
