check if you can release the
park ing brake . After re leas ing the parking
brake, carefu lly drive to your authori zed
Audi dealer immed iately to have the mal­
function corrected. If you cannot re lease the
parking brake, seek professional assistance .
- If the indicator light and the message ap­
pear
w hile dr ivin g, the emergency braking
function may not be ava ilable . It may not be
poss ible to set the parking brake o r release
it once it has b een set. Seek professional as­
s istance.
(USA models): If the warning light
1111 and
the warning light
EiJ appear together, imme­
d iate ly contact your authorized Aud i dealer or
qua lified workshop to have all b rake pads in­
spected
Q page 20 .
When the light comes on, an audible warning
signal is also give n.
A WARNING
- Always observe the wa rnings in
Q page 231, before opening the hood
and checking the brake fluid .
- Driv ing with low b rake fluid is a safety
haza rd. S top the car and get professional
assista nee .
- If the
1111 (USA models)/ . (Canada
mode ls) b rake system indicator light
turns on together with the ABS and ESC indicator lights, the ABS/ESC regu lating
function may have failed. F unctions that
stabilize the vehicle are no longer availa­
ble. Th is could cause the vehicle to
swerve and increase the risk of sliding .
Drive carefully to the nearest authorized
Audi dealer or other qualified workshop
and have the malfunction cor rected.
- If the brake warning/indicator light does
not go out afte r a few seconds and the
par king brake is released, or ligh ts up while you are driving, the fluid leve
l in
the brake fl uid reservo ir is too low. If you
believe that it is safe to do so, proceed
immed iate ly at low speed to the nearest
author ized Audi dealer or qualified repair
facility and have the brake system in­ spected.
- Always keep in mind that after severa l
brake applications, you will need greater
pressu re on the brake pedal to stop you r
veh icle. Do not rely on st rained bra kes to
respond with maximum stopping powe r
in critical situations . You must allow for
increased braking distances . The extra
distance used up by fading brakes could
lead to an accident.
PARK/( ®) Electromechanical parking
brake
The warning/indicator light monitors the
electromechanical parking brake .
If the indicator light - (USA models) /.
(Canada models) turns on, th@ parking brake
was set. If the parking brake is set when the
ignition is off, the indicator light turns off af­
ter about 20 seconds.
The warning/indicator light will go out when
the parking brake is re leased.
- (USA model s) ,. (Canada model s)
Caut io n: Vehicle parked too steep
If the indicator light blinks and the message
appears, there is not enough braking power to
keep the vehicle from rolling. The brakes have
overheated. The vehicle could roll away even
on a small incl ine .
Pre ss brak e ped al t o relea se p arking b rake

to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, yo u shou ld use the b rak ing
effect of the engine. Th is way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously. P ump the brakes at inter ­
vals.
Operating nois e
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
E ff ect of water and road salt
In certain situat ions, for example after driving
through water , in heavy ra in , after overn ight
condensation or after washing your car, the braking effect can be reduced by moisture or
ice on the brake rotors and brake pads. The
brakes must be dried first with a few careful
brake applications.
At higher speeds and with the windshield wip­
ers turned on, the brake pads press against
the brake rotors for a short amount of time.
This occurs at regular intervals without the
driver noticing and provides for bet ter brake
response time under wet condit ions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered
road and the brakes are not used . Likew ise,
you clean off accumulated salt coating from
brake discs and pads with a few caut ious ap­
plications of the brake
9 .&, .
Cor ro sion
There may be a tendency for dirt to build up
on the brake pads and corrosion to form on
the discs if the car is not dr iven regularly or
only for short t rips with little use of the
b rakes .
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
firm ly a few times from a mode rately high
speed
9 .&, .
Faults in the brake syste m
If you shou ld notice a sudden increase in
brake pedal trave l, then one of the two brake
circuits may have fai led
9 & .
Low bra ke fluid lev el
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake flu id
level is monitored electro nica lly.
Brake lining we ar statu s
Brake lining wear may be checked by visual in­
spect ion of the condition of the brake pads
th rough the open ings in the wheel. If neces ­
sary, the wheel may be removed for t his i n­
spect ion
9 page 2 72, Changing a wheel.
A WARNING
- You shou ld 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 descending a steep grade, reduce
speed and sh ift transmission into a lower
gear or lower dr iving range. Do not ride
the brakes or hold the pedal down too
long or too often . This could cause the
b rakes to get hot and diminish braking
efficiency.
- Do not "ride the brakes" by rest ing your
foo t on the pedal when you do not intend
to brake. This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Unde r certain cl imatic and operat ing
conditions such as passing thro ugh wa ­
ter, driving in heavy rain or after washing
the vehicle, the effectiveness of the brakes can be reduced. In winter, ice can
accumu late on the brake pads, linings,
d iscs and drums. Carefully app ly brakes
for a test. Brakes will dry and ice coat­ ings will 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 bra king efficiency.
~

Clean off accumulated salt coating from
brake discs and pads with a few careful
brake applicat ions .
-If you damage the front spoiler, or if you
install a different spoiler, be sure the air
flow to the front brakes is not obstruct­ ed . Otherwise the brake system could
overheat reducing the effectiveness of
the ent ire brake system.
- Failure of one brake c ircuit will impair
the braking capability resulting in an in­
cr eased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dea ler or q ualified wor kshop .
- Never let the vehicle rol l to a stop w ith
t he engine shu t off.
- If the brake booster is not work ing, the
brake pedal must be pressed conside ra­
bly harder to make up for the lac k of
booster assistance.
Brake booster
The brake booster adds extra braking power.
The brake booster works w ith vacuum pres ­
sure which is created only when the engine is
ru nning
9 ,&. .
,&. WARNING
-Never le t the vehicle ro ll to a stop w ith
t he engine shu t off.
- If the brake booster is not work ing, fo r
ex ample when towing your ve hicl e, or
because the b rake booste r has somehow
been damaged, the brake pedal must be
pressed considerab ly harder to make up
for the lack of booster assistance.
Servotronic - advanced
power steering system
-
The power steering systems use the power of
the running engine to allow precise steering
with little effort.
The advanced Servotronic power steering sys­
tem senses the road speed and electron ically

Int ellig ent technolog y 203
ble and safe steering response exactly match ­
ed to th e vehicle speed .
Power steer ing will not work if the engine is
off . As a result, the steering wheel will be h ard
to tu rn.
T he powe r stee ring fluid level is checked d ur­
i ng t he sched uled maintena nce services.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will s till fu nction like a conven­
tiona l powe r steering system, providing a
constant steering s upport force tha t is no
l onge r proportionate to the vehicle speed.
This is most noticeab le when t urni ng the
steering wheel at low speeds (for example
when parking), -more effort w ill be re­
quired than usual.
- Be aware of the different than usual steering response and adjust your steer­
ing force accordingly.
- Have the problem checked and set right by an Audi dealer as soon as possible.
(D Tips
-When the engine is running, never hold
the steering wheel turned all the way to
the right or to the left for longer than 15
seconds . The power steering pump will
overheat the hydraulic fluid if yo u keep
holding the stee ring wheel turned all the
way. This is likely to damage the power
steering sys tem.
- If the powe r stee ring system should fa il
entire ly, o r if t he engine is not runn ing
(for example, wh ile be ing towed), you
w ill still be able to steer the veh icle .
However,
considerably more effort will
be required to do so .
- If the powe r steering system sho uld
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immediately.
- The power steering system req uires a
specially formu lated hydraulic fluid. The
power steering fluid reservoir is located
in the engine compartment

Trailer load distribution Be sure the load in the trailer is held securely
in place to prevent it from shifting forward,
backward or sideways.
Never allow a passenger to ride in a trailer
¢ .&. in Driving instructions on page 214.
Engine cooling system
Towing a trailer makes the engine work hard ­
er . It is important that the cooling system's
performance is up to the additional load .
Make sure that the cooling system has enough
fluid.
Tire pressure
When towing a trailer, inflate the tires of your
vehicle to the cold tire pressure listed under
"Full load" on the label located on the driver's
side B-pillar (visible when the door is open).
Inflate trailer tires to trailer and tire manufac­
turers' specifications.
Lights
Check to make sure both vehicle and trailer
lights are working properly.
Safety chains Be sure trailer safety chains are properly con­
nected from the trailer to the hitch on the ve­
hicle . Leave enough slack in the chains to per­
mit turning corners . When you install safety
chains, make sure they will not drag on the
road when you are driving.
The chains should cross under the trailer
tongue to prevent it from dropping in case of
separation from the hitch .
Adjusting the Audi drive select Make sure the vehicle is on a level surface
be­
fore
hitching up the trailer and before adjust ­
ing the tongue weight. The vehicle must be in
auto or comfort driving mode and not raised
¢page 110, ~CD .
Make sure that the vehicle is lowered. In Info ­
tainment, select:
ICARI function button> low­
er control button .
Trailer towing 213
If you must drive under poor road conditions,
you can raise the vehicle
after coupling the
trailer or
after adjusting the tongue weight
¢ page 112.
@ Note
- Changes in temperature or load can af­
fect the height of the vehicle.
- Always select auto or comfort mode.
Otherwise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the following:
.,. Do not tow a loaded trailer when your car it­
self is not loaded .
.,. Be especially careful when passing other
vehicles.
.,. Observe speed limits.
.,. Do not drive at the maximum permissible
speed .
.,. Always apply brakes early .
.,. Monitor the temperature gauge.
Weight distribution
Towing a loaded trailer with an empty car re­
sults in a highly unstable distribution of
weight. If this cannot be avoided, drive at very
low speeds only to avoid the risk of losing
steering control.
A "balanced" rig is easier to operate and con­
trol. This means that the tow vehicle should be loaded to the extent possible and permissi­
ble, while keeping the trailer as light as possi­
ble under the circumstances . Whenever possi­
ble , transfer some cargo to the luggage com­
partment of the tow vehicle while observing
tongue load requirements and vehicle loading
considerations.
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the rig. Do not .,.
