Braking
General information
What affects braking efficiency?
Operating condition s and dri ving h abit s
The brakes on today's automobiles are still
subject to wear, depending largely on operat
ing condit ions and driving habits ¢.&, . On
vehicles that are either driven mostly in stop
and-go c ity traff ic or are dr iven hard, the
brake pads should be checked by your author
ized Audi dea ler more often th an specified in
the
Warran ty & Maintenan ce boo kle t. Failure
to have you r brake pads inspected can result
in reduced brake performance .
On steep slopes, you sho uld use the braking
effect o f the engine . This way, you prevent un
necessary wear on the b rake system. If you
must use your brakes, do not hold the brakes
down cont inuous ly. Pump the brakes at inter
vals.
Mo istur e or road salt
U nder certain conditions , for example, when
driving through water or very heavy rain , or
even after washing your vehicle, the braking
effect can be reduced due to moisture (or in
free zing cond itions ice) on the brake pads. A
few carefu l brake applications should dry off
the brake pads or remove any ice coatings .
When you are driving at higher speeds with
the windshield w ipers on, the brake pads will

200 Intellig ent technol ogy
briefly touch the brake d iscs in regular inter
va ls so as to improve reaction time when brak
ing on wet surfaces. You the driver wi ll not no
tice anything.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Here too,
you should clean off accumu lated salt coating
from brake discs and pads with a few careful
applicat ions of the brake¢,& .
Co rrosion
There may be a tendency for dirt to bui ld up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short trips with little use of the
brakes .
If the brakes are not used frequently, or if cor rosion has formed on the discs, it is advisable
to clean off the pads and discs by braking
firmly a few times from a moderately high
speed <=>,& .
Fa ul ts in th e brak e sys te m
If you should notice a sudden increase in
brake pedal travel, then one of the two brake
circu its may have failed¢,& .
Low b rak e flu id l evel
Malfunctions can occur in the brake system if
the brake fl uid level is too low. The brake fluid
level is monitored electronically .
Brake booster
The brake booster wor ks w ith vacuum pres
sure which is created only when the engine is running
c> ,& .
Brake lining wear st atu s
Brake lining wea r may be checked by visual in
spection of the condition of the brake pads
through the openings in the whee l. If neces
sary, the wheel may be removed for this in
spection ¢ page 269, Changing a wheel .
_& WARNING
-You should perform braking maneuvers
for the purpose of cleaning the brake
system only if road conditions permit .
Other road users must not be put at risk -
you may ca use an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gear o r lower dr iving range. Do not ride
the br akes or ho ld the pedal down too
long o r too often . T his could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by resting your foot on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operat ing
conditions such as passing through wa
ter, dr iving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced . In winte r, ice can
accumu late on the bra ke pads, lin ings,
d iscs and drums. Carefully app ly bra kes
for a test. Brakes will dry and ice coa t
ings wi ll be cleaned off after a few care
fu l brake applicat ions.
- Driving for an extended period of t ime on
salt -covered roads without using your
brakes can a lso affect braking efficiency .
Clean off accum ulated salt coating from
brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you
install a different spoiler, be sure the a ir
f low to the front brakes is not obstruct
ed. Otherwise the brake system could
overheat reducing the effective ness of
the entire brake system.
- Failure of one brake circuit will impa ir
the braking capab ility result ing in an in
creased stopping distance . Avoid driving
the vehicle and have it towed to the near
est A udi dealer or qualified workshop .
- Never let the vehi cle roll to a s top with
the eng ine shut off.
Catalytic converter
It is very important that your emission control system (catalytic converter) is function
ing properly to ensure that your vehicle is run
ning in an environmentally sound manner .
.. Always use lead-free gasoline¢ page 225,
Fuel supply.
.,. Never run the tank down all the way to
empty.
.,. Never put too much motor oil in your en-
gine
¢ page 235, Adding engine oil~-
.,. Never try to push- or tow-start your veh icle.
The catalytic converter is an eff icient "clean
up" device built into the exhaust system of
the vehicle . The catalytic converter burns
many of the pollutants in the exhaust gas be
fore they are released into the atmosphere.
The exclusive use of unleaded fuel is critically
importa nt for the life of the cata lytic convert
e r and proper functioning of the engine.
A WARNING
-
- Do not park or operate the vehicle 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 pipes, catalytic con
verter or heat shields. During driving, the
substance used for undercoating cou ld
overheat and cause a fire.
0 Note
- Be aware that just one tank filling with
leaded fuel will already seriously de
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil level
¢ page 235.
-Do not drive until the fuel tank becomes
completely empty. The eng ine could mis
fire . U nburned fuel could a lso get i nto
Dri vin g and en vironm ent 205
the exhaust system and this cou ld cause
the catalytic converter to overheat .
- Do not switch off the ignit ion while the
vehicle is mov ing.
- Do not continue to ope rate your veh icle
unde r these conditions, as othe rwise fuel
can reach the catalytic converter. This
co uld result in overheating of the con
verter, requir ing its replacement .
- To assure efficient operation of the Emis
sion Control System:
- H ave your vehicle maintained prope rly
and in accordance w ith the se rv ice rec
ommendat ions in you r Warranty &
M aintenance boo klet.
- L ack of prope r maintenance as we ll as
improper use of the vehi cle w il l impair
the function of the em ission contro l
system and could lead to damage .
@ For the sake of the environment
Even when the Emiss ion Control System is
operat ing properly, the exha ust gas can
have a sul fur -li ke exhaust gas smell under
some operating states . This depends on
the sulfur content of the fuel being used .
Using a different brand of fue l may help,
or filling the tank with lead-free super
grade gasoline .
Avoid damaging the
vehicle
When you are drivi ng on poo r roads, or over
c ur bs, s teep ramps, etc., ma ke certai n that
low -lying parts s uch as spoilers and exhaust
system pa rts do not bottom o ut and get dam
aged.
T h is is espec ially true for veh icles w ith low
s lung chassis (spor ts chassis)* and fully load
ed vehicles. •
•
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
11-Try and keep well below your car's maxi-
mum speed.
Accelerating gently reduces fuel consump tion, engine wear, and does not disturb the
environment.
F ue l consumption, exhaust emissions and en
g ine noise increase disproportionately at high
speeds. If you drive at approximately three
quarters of top speed, fuel consumption will
be reduced by one half. Never drive faster
than the posted speed limit and weather con
d itions permit .
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
11-Shut the engine off when you are not driv
ing the vehicle.
"" Do not warm up the veh icle by letting the
engine run at idle .
The idling phase is automat ically reduced for
vehicles w ith the Start/Stop system . It is effi
cient to switch
off the engine in vehicles with
out the Start-Stop-System when stopped at ra il road crossings and long red lights. Turning
the eng ine
off for just 30 -40 seconds saves
mo re fuel than is burned by s tarting the en
gine again.
It takes a long time fo r the engine to wa rm up
fu lly when it is running at idle. Howeve r, wear
and noxious emissions 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 h igh rpms while the engine is
still warming up.
CD Note
Do not leave engine idling unattended af
ter starting. If warning lights shou ld come
on to indicate improper operation, they
Dri vin g and en vironm ent 207
would go unheeded. Extended idling a lso
produces heat, which could result in over
heating or other damage to the veh icle or
other property.
Regular maintenance
A badly tuned engine unnecessarily wastes a lot of fuel.
11-Have your vehicle serviced at reg ular inter-
vals .
By having your ve hicle reg ularly se rviced by an
Audi dealer he lps to ensure that it runs prop
erly and economically . The condition of your
vehicle not only affects its safety and ability to
ho ld its va lue, it also affects
fuel co nsump
tion .
Chec k your oil e ach t ime you fill y our t ank.
T he amou nt of o il used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reac h its lowest value after a certa in
mileage has bee n driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also applies to fuel consumption and en gine output .
CD Note
-Have your veh icle ma inta ined properly
and in accordance with the service rec
ommendations in your Warranty
& Ma in
tenance book let . Lack of proper mainte
nance as well as improper use of the ve
hicle will impai r the function of the
em ission cont ro l system and cou ld lead
t o damage.
- Do not alter or remove any component of
t he Emission Control System unless ap
proved by the manufacture r.
- Do not alter or remove any devi ce, such
as heat shie lds, switches, ign ition w ires,
valves, which are designed to protect
your vehicle's Emission Control System
