A WARNING
-Always observe the warnings in
c> page 165, Working in the engine
compartment, before opening the en­
gine hood and check ing the bra ke fluid.
- Driv ing with low brake fluid is a safety
hazard! Stop the car and get professional
assistance. -
USA models: If both, the
1111 warning
light and the
E warn ing light come
on at the same time, the rear wheels
could lock up first under hard braking.
Lock-up of the rear wheel brakes can
cause loss of vehicle contro l and an acci­
dent. Have your veh icle repa ired immedi­
ately by your authorized Audi dealer or a
qualified workshop . Drive s low ly and
avoid sudden, hard brake application.
- Canada models:
If both, the b rake warn­
ing light . and the ABS warning light
EiJ come on at the same time, the rear
wheels could lock up f irst under hard
brak ing. Lock-up of the rear wheel brakes
can cause loss of veh icle control and an
accident. Have your vehicle repaired im­
mediately by your author ized Audi dealer
or a qualified wo rkshop. Drive slowly and
avoid sudden, hard brake application.
- If the b rake warning/ind icator light does
not go out after a few seconds and the
pa rking brake is re leased, or lights up
while you are dr iving, the flu id leve l in
the brake fl uid reservo ir is too low . If you
believe that it is safe to do so, proceed
immediate ly at low speed to the nea rest
author ized Audi dealer or qualif ied work­
shop and have the brake system inspect­
ed.
-Always keep in mind that after severa l
brake applications, you will need greater
pressure on the brake pedal to stop your
veh icle. Do not rely on strained brakes to
respond with maximum stopping powe r
i n critical s ituations. You must allow for
increased b raking dis tances. The extra
distance used up by fading bra kes could
lead to an accident.
tli1 !.!r Safety systems
The I ( U SA models) . (Canada mode ls) in­
dicator light monitors the safety systems e.g.
(airbags, pretensioners) and i lluminates for a
few seconds each time you switch the ignitio n

@ For the sake of the environment
To avoid unnecessary engine wear and to reduce exhaust emissions, do not let your
vehicle stand and warm up. Be ready to
drive off immediately after start ing your
veh icle. Mainta in moderate speed until the
engine is completely warm . Remember,
the engine performs best at operating
temperature .
Stopping the engine
.,. Turn the ignition key to position @
¢page 73, fig. 82.
_& WARNING
-Never turn off the engine before the ve­
hicle has come to a complete stop. The
full function of the brake booster and the
power steering is not guaranteed. You
must use more force to turn or brake if
necessary . Because you cannot steer and
brake as you usually would, this could
lead to crashes and serious injur ies.
- The radiator fan can continue to run for
up to 10 minutes even after you have
turned off the eng ine and removed the
ignition key. The radiator fan can also
turn on again if the engine coolant heats
up because of intense sunlight or heat
build-up in the engine compartment .
(D Note
Do not stop the engine immediately after
hard or extended driving. Keep the engine
r un ning for approximately two minutes to
prevent excessive heat build-up.

If you should drive off with the parking brake
still set, a warning tone will sound and the
follow ing will appear in the instrument clus­
ter to rem ind you to release the parking
brake:
Parking brake set
The parking brake warning comes on only af­
ter you have driven for longer than 3 seconds
and faster than 5 mph (5 km/h) .
The parking brake warning light_
(USA)/ . (CON) illuminates when the park­
ing brake is set and you switch on the ignition .
A WARNING
Always re lease the park ing brake com -
pletely. A partially engaged brake will
overheat the rear brakes, reduce their ef­
fectiveness and cause excessive wear. This
could lead to brake failure and an accident. .,.

because if the vehicle starts to roll
backward, you could cause an accident. If
the clutch should start to slip, you will
feel the vehicle "jerk" and the selector lever display will start blink ing.
- Before driving down a steep slope, re­
duce your speed and shift into a lower gear with "tiptronic".
- Do not ride the brakes or apply the brake
pedal too often or too long . Constant
braking causes the brakes to overheat
and substantially reduces braking per­
formance, increases braking distance or
causes complete failure of the brake sys­
tem.
Hill Descent Assist
Applies to vehicles: with S tro nic
Hill Descent Assist helps the driver when driv ­
ing down inclines .
Hill Descent Ass ist is activated by pressing the
b rake wh ile descending when the selector lev­
er is in D/S. The S tronic transmission auto­
mat ically shifts down to a gear suitab le for
the incline. Hill Descent Assist attempts to
maintain the current vehicle speed when the
brak ing occurs, as far as phys ical and techni ­
cal limits allow. It may be necessary to adjust
the speed using the brakes.
Hill Descent Assist switches off when the in­
cline levels out or when the gas pedal is press­
ed.
On vehicles w ith cruise control*~
page 78,
Hill Descent Assist is also activated when the
speed is set.
_&. WARNING
Hill Descent Assist cannot overcome phys i­
cal limitations, so it may not be possible to
ma intain a constant vehicle speed under
all circumstances . Always be ready to ap­
ply the brakes .

switched on all the time. In certain situations
when you need less traction, you can switch
off ESC by pressing the button
lru. Be sure to
switch ESC on again when you no longer need
less traction.
Anti-lock braking system (ABS)
ABS prevents the wheels from locking up
when braking . The vehicle can still be steered
even during hard braking . Apply steady pres ­
sure to the brake pedal. Do not pump the ped­
al. A pulsing in the brake pedal indicates that
the system is helping you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking
d istance. It increases braking power when the
driver presses the brake pedal quickly in emer­
gency si tuations. You must press and hold the
brake pedal until the situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to
the road condit ions. This makes it easier to
start, accelerate and drive up hills.
Electronic differential lock (EDL)
The EDL brakes wheels that are spinning and
transfers the drive power to the other drive
wheel or whee ls if the vehicle is equipped with
all-wheel drive*. This function is available up
to about 60 mph (100 km/h) .
In extreme cases, EDL automat ica lly switches
off to help keep the brake on the braked wheel
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to
normal.
..&, WARNING
- ESC, ABS, ASR and EDL cannot overcome
th e laws of physics. This is especially im ­
portant on slippery or wet roads.
If the
systems begin acting to stabilize your ve­
hicle, you should immediately change
your speed to match the road and traffic
condit ions. Do not let the increased safe­
ty provided by these systems tempt you
Intelligent technology 143
to take risks. Doing so will increase the
risk of a lo ss of vehicle control, co llision
and serious personal injuries.
- Always adapt your speed to road, traffic
and weather conditions. The risk of los­
ing control of the vehicle increases when
driving too fast, especially through
curves and on slippery or wet roads, and
when driving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL and ASR cannot prevent colli­
sions.
- Always accelerate with special care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even with
these assistance systems that cannot al ­
ways he lp to reduce the risk of loss of ve­
hicle control.
@ Tips
- ABS and ASR only work correct ly when
all four whee ls are equipped with identi­
cal tires. D ifferent tire si zes can lead to a
reduction in engine power.
- You may hear noises when the systems
described are working.
- If the ind icator lightD] orE (USA
models)/ [iJ (Canada models) appears,
there may be a malfunction¢

General information
What affects braking efficiency?
Oper ating condit ions and d riving hab it s
T he brakes on today's automobi les are st ill
s ubject to wear, depending largely on opera t­
ing conditions and dr iv ing habi ts
c> & . On
vehicles that are e ither driven mostly in stop ­
and-go city traffic or are d riven hard , the
b rake pads should be checked by you r author­
i zed Audi dealer more often than specified i n
the
Warr ant y & Maint enan ce booklet . Failure
to have your brake pads inspected can res ult
in red uced brake performance.
On steep slopes, you shou ld use the brak ing
effect of the eng ine. This way, you p revent un­
necessa ry wear on the brake system . If you
must use yo ur brakes, do not hold the brakes
down continuously. Pump th e brakes at inter­
vals.
Noises may occur when braking d epending on
the speed, braki ng force and outside condi­
tions such as temperature and humidity.
Moistu re or road salt
Unde r certain conditions, for example, w hen
driving through water or ve ry heavy rain, or
even after washing your vehicle, the braking
effect can be reduced d ue to moisture (or in
fre ezing conditions ice) on the brake pads . A
few ca utious brake applicat ions should dry off
the b rake pads or remove any ice coatings.
The effectiveness of the brakes can be reduced
when th e vehicle is driven on a salt-covered
Int ellig ent technolog y 145
road and the b rakes are no t used. Likewise ,
you clean off accumulated salt coating from brake d iscs and pads with a few cautious ap ­
plications of the brake
c> & .
Cor ro sion
T here may be a tendency for dir t to build up
on the brake pads and corrosion to form on
the discs if the car is not driven regu larly or
on ly fo r short trips with litt le 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
c> & .
Faults in the brak e syst em
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
c ircuits may have fai led
c> & .
Low brake fluid lev el
Malfunctions can occur in the brake system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake booster
T he brake booster inc reases the pressure that
you generate with the brake peda l. It works
o nl y when the engine is running
.c> &
Brake lining wear status
Brake lining wear may be checked by visual in­
spection of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the wheel may be removed for t his in­
spection

aware of when changing a tire? .
A 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 cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
