• Wh en you lock your vehicle from outs ide , nobody - especially
c hildren - should remain in side the vehicle . Remember , when you
lo ck the vehicle from the outside the windows cannot b e opened
from the inside .
• When you lea ve the vehicle, always remove the ignit ion key
and take it with you. This will prevent pa ssenger s (c hildren, for
e xample ) from a ccidentally be ing locked in the vehicle should
they accidentally pres s the power locking switch in the front
doors .
• Do not leave children inside the vehicle unsuperv ised . In an
e mergency it would be impossible to open the door s from the
outside without the key.
[I] Tips
It is not possible to re -open the door fo r a b rief period directly after
clos ing it . This a llows you to ensure that the doors are p roper ly

In freezing or nea r freezing condi tions:
• Always check that the wiper blades are not frozen to the glass
before you turn the wipers on. Loosen a w iper blade wh ich is frozen in
place before operating the wipers to prevent damage to the w iper
blade or the wiper motor.
• Do not use the wipers to clear a frosted window. Using the wipers
as a convenient ice scraper will destroy the w iper blades .
• Prior to using a car wash, the windshield wiper system mus t be
switched off (lever in position 0) , This helps to prevent unintentional
switching on and damage to the windshield wiper system .

Before you move the selector lever from t he P position, yo u must
a lw ays app ly the b rake ped al befo re and while dep ress ing the bu tton
in the handle of the selector lever.
& WARNING
• Unintended vehicle movement can cause serious injury.
- When the selector lever is in a driving position, the vehicle
may creep, even at idle speed. Therefore do not release the
parking brake o r foot brake until you are ready to move ,
because power is transmitted to the wheel s as soon as a driving
position i s engaged.
- Do not accelerate while selecting a driving position. At this
time the engine must be at idle speed so that undue stre ss is
not placed on the clutches in the tran smission.
- Remember: -even when stopped briefly with the automatic
tran smission in "D ", "S" or "R ", engine power is being trans­
mitted to the wheels. Your vehicle could "creep" forward or
backward. When stopped, keep the brake pedal fully
depressed and use the parking brake if necessary to keep the
vehicle from rolling .
• If the selector lever is unintentionally moved into N while you
are driving, take your foot off the acc elerator pedal and wait for
the eng ine to return to idle speed before selecting a driv ing posi­
tion .
• Never shift into "R " or "P" when the vehicle is in motion.
• Never get out of th e driver's seat when the engine is running .
• If you must get out of the vehicle, move the selector lever
securely into the P pos ition and apply the parking brake firmly.
• If the engine must remain running, never have any driving
position engaged when checking under the hood . Ma ke sure the
s elector lever ha s securely engaged and is locked in "P" with the
parking brake firmly set=> page
290, "Engi ne compartment".
Otherwise, any increa se in engine speed may set the vehicle in
motion, even with the parking brake applied. •

The ASR works in conjunction with the ABS. If a malfunction should
occur in the ABS, the ASR w ill also be out of action.
& WARNING
The increased safety afforded by ASR does not mean that you can
take safety risks. Always adapt your driving style to the road
conditions and traffic situation.
[ i] Tips
To ensure that the ASR works properly, all four whee ls must be fitted
with ident ical tires. Any differences in rolling radius of the tires can
cause the system to reduce engine power when th is is not desired.

Braking
General information
What affects braking efficiency?
Operating conditions and driving habits
The brakes on today's automobiles are still subject to wear,
depending large ly on operating conditions and driving habits=>& .
On vehicles that are either driven mostly in stop -and -go city traffic or
are driven hard, the brake pads should be checked by your authorized
Audi dealer more often than specified in the
Warranty & Mainte­
nance booklet.
Failure to have your brake pads inspected can result
in reduced brake pe rformance .
On steep slopes, you should use the brak ing effect of the engine . This
way, you prevent unnecessary wear on the brake system. If you must
use your brakes, do not hold the brakes down continuously. Pump the
brakes at intervals.
Noises may occur when braking depending on the speed , braking
force and outside conditions such as temperature and humidity.
Safety first
Moisture or road salt
If you are driving faster than 31 mph (SO km/h) and the windshield
wipers are on, the brake pads wi ll briefly touch the brake discs in
regular interva ls so as to improve reaction time when braking on wet
surfaces . You, the driver, will not not ice anything.
Under certain cond itions, for example, when driving through wa ter or
very heavy rain, or even after washing yo ur vehicle , the braking effect
can be reduced due to moisture (or in free zing conditions ice) on the
brake pads. A few careful brake applications should dry off the brake
pads or remove any ice coatings .
The effect iveness of the brakes can be reduced when the vehicle is
dr iven on a sa lt-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 applications of the brake=> & -
Corrosion
There may be a tendency for dirt to build up o n the brake pads and
corrosion to form on the dis cs if the car is no t driven regularly or only
for short trips with little use of the brakes.
If the brakes are not used frequently, or if corrosion 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=> &.
Faults in the brake system
If you should notice a sudden increase in brake pedal travel, then one
o f the two brake circuits may have failed==>& .
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is
too low. The brake fluid level is monitored e lectron ically .
Brake lining wear status
Brake lining wear may be checked by visual inspection of the condi­
tion of the brake pads through the openings in the wheel. If neces­
sary, the wheel may be removed for this inspection =>
page 343,
"Changing a wheel". ._.

Intelligent technology
'-----------------------------------------------
in. WARNING
• You should perform braking maneuvers for the purpose of
cleaning the brake system only if road condition s permit. Other
road u sers must not b e put at r isk - you may cau se an ac cident!
• Before d esc ending a steep gr ade , redu ce speed and shift tran s­
mission into a lower gear or lower driving range. Do not ride the
brakes or hold the pedal down too long or too often . This could
cause the brake s to get hot and diminish braking efficiency.
• Do not "ride the brakes " by re sting your foot on the pedal when
you do not intend to brake. Thi s may caus e the brakes to overheat ,
premature wear and increa sed stopping di stance.
• Under certain climatic and operating conditions such as
pas sing through water, driving in heavy rain or after washing the
vehicle, the effectiveness of the brake s can be reduced . In winter,
ice can accumulate on the brake pads , linings , disc s and drums .
Carefully apply brakes for a test. Brake s will dry and ice coatings
will be cleaned off after a few careful brake applications.
• Driving for an extended period of time on salt -cov ered roads
without using your brakes can al so affect braking efficiency. Clean
off accumulated salt coating from brake d iscs and pads with a few
careful brake applications.
• If you damage the front spoiler , or if you install a different
s poiler , be sure the air flow to the front brakes is not obstructed.
Otherwise the brake system could overheat reducing the effective­
ness of the entire brake system.
• Failure of one brake circuit will impair the braking capability
resulting in an increased stopping distance. Avoid driving the
vehicle and have it towed to the nearest authorized Audi dealer or
qualified wo rkshop. •
Brake booster
The brake booster adds e xtra brakin g pow er .
The brake booster works with vacuum pressure which is created only
w hen the en gine is ru nning =>& .
in. WARNING
• Never let the vehicle roll to a stop with the engine shut off .
• If the brake booster i s not working , for example when towing
your vehicle , or because the brake booster has somehow been
damaged , the brake pedal must be p ressed considerably harder to
make up for the lack of booster assistan ce.
Functioning of Anti-Lock Brake System
(ABS)
AB S prevents the wheels from locki ng up under braking.
T he ABS co ntribu tes effectively to vehicle co ntrol s ince it prevents t he
w hee ls from
locking when the b rakes are a pplied. This means t hat t he
veh icle rema ins steerable and is less likely to s kid .
W ith ABS you do not need to
pump the brake. Just hold the brake
pedal down .
However, do not expect the ABS to shorten braking distance u nder
oil
circums tances. When driving on grave l or on newly fa llen snow on top
of icy su rfaces, braking dis tance may be even longer, therefore, under
these c irc umstances, it is especially important that you dr ive slowly
and w it h great care .
How the ABS system works
An automatic check is made when a speed of about 12 mph (20 km/h)
is reached . Whe n this happens, a p umping noise can be hea rd. ._
