118 Autom atic Tran smissi on
preve nt the vehicle from "creep ing" , you
must keep your foot on the brake in all
selector lev er positions except P and N
when the e ng ine is r unning. Do not inad­
vertently press the accelerator pe dal
w hen the veh icl e is stationary . Otherwise
the vehicle will s tart to move immediate­
ly, even if the park ing brake is se t. This
cou ld result in a c rash.
- Do not ride the brakes or press the brake
peda l too often or too long when dr iving
down a hill. Constant braking causes the
brakes to ove rheat and s ubstant ially re­
duces braking performance, increases
braking distance or causes comp lete fail­
ure of the brake system.
Hill descent control
The hill descent control system assists the
driver when driving down declines.
H ill descent control is activated when these­
lector lever is in D/S and you press t he b rake
pedal. The transmission automat ically se lects
a gear that is suitab le for the incline. Hill de­
scent control tries to maintain the speed ach­ ieved at the time of brak ing, within physical
and techn ical limitations. If may still be nec­
essary to adjust the speed with the brakes .
H ill descent control switches off once the de­
cline levels out or you press the accelerator
pedal.
Hill descent control is also activated when the
speed is set by starting the cruise control sys­
tem c:>
page 90.
A WARNING -
Hill descent control ca nnot overcome
physical limitations, so it may not be able
t o maintain a constant speed under all
condi tion s. Alw ays be ready to ap pl y the
bra kes.
Shifting manually
The shift paddles allow the driver to shift the
gears manually .

Kick-down
Kick-down enables maximum acceleration .
When you press the accelerator pedal down
beyond the resistance point, the automatic
transmission downsh ifts into a lower gear, de­
pending on veh icle speed and eng ine RPM . It
shifts up into the next higher gear once the
max imum specified engine RP M is reached .

ESC includes and/or works together with the
anti-lock braking system (ABS), brake assist
system, anti-s lip regulat ion (ASR), electronic
d ifferential lock (EDL), dynamic steering* and
electronic interaxle differential lock*. ESC is
sw itched on all the time . In certain s ituations
when you need less tract ion, you can sw itch
off ASR by pressing the button above
~ page 200, fig. 188 the se lector lever. Be
sure to sw itch ASR o n aga in when yo u no lon­
ger need less traction.
Anti -lock braking system (ABS)
ABS prevents the wheels from locking up
when braking. The veh icle can still be steered
even du ring ha rd b raking . Apply steady p res­
sure to the brake pedal. Do not p ump the ped­
a l. A pulsing in the brake peda l indicates that
the system is he lping you to brake the vehicle .
Brake as sist system
The brake assist system can decrease bra king
d istance.
It increases braking power when the
driver presses the brake pedal qu ick ly in eme r­
gency situations . You must p ress and ho ld the
brake peda l until the situation is over. In
vehicles with adaptive cruise control*, the
brake assist system is more sensit ive if the
d istance detected to the vehicle ahead is too
small.
Anti- slip regulati on (A SR )
ASR reduces engine power when the drive
wheels begin to spin and adapts the force to the road condit ions. This makes it eas ier to
start, accelerate and drive up hills.
Electronic diff erential lo ck (EDL )
The ED L 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 whee l drive*. This funct ion is available up
to about 75 mph (120 km/h).
In extreme cases, EDL automatica lly switches
off to help keep the brake on the braked whee l
from overheating. EDL w ill switch on again au­
tomatically when conditions have returned to normal.
Int ellig ent technolog y 199
Dynamic ste ering *
On vehicles with dynam ic steering, ESC helps
stabilize the steering in certain situations.
Electronic intera xle differential l ock
function*
T he electron ic i nteraxle differential lock f unc ­
tion activa tes when dr iving th ro ugh curves.
Braking is targeted toward the wheels on the
inside of the curve as needed. This he lps to
minimize front whee l skid, improves traction
and allows for more precise driving through curves .
A WARNING
- ESC, ABS, ASR, EDL, dynamic steering*
and the elect ronic interaxle differential
loc k function* cannot ove rcome the laws
of physics. This is espec ially important
on slippery or we t roads.
If the systems
begin acting to stabilize your veh icle, you
should immediately change yo ur speed
to match the road and traffic conditions .
Do not let the increased safety provided
by these systems tempt you to take risks.
Doing so will increase the risk of a loss of
veh icle contro l, collision and ser ious per­
sonal injur ies.
- Always adapt your speed to road, traffic and weather conditions. The risk of los­ing con trol of the vehicle increases when
driving too fast, espe cially through
curves a nd on slippe ry or wet roads, and
when dr iving too close to vehicles up
ahead. ESC, ABS, the brake assist sys­
tem, EDL, ASR, dynam ic steering* and
the electron ic interaxle d ifferential lock
function" cannot prevent co llisions.
- Always accelerate with spec ial care on
even, smooth surfaces such as those that
are wet or covered with ice and snow.
The drive wheels can spin even w ith
these assistance systems that cannot al­
ways he lp to red uce the risk of loss of ve­
hicle control.

Braking
General information
What affects braking efficiency?
-
Operating conditions and driving habits
The brakes on today's automobiles are still
subject to wear, depending largely on operat­
ing condit ions and driving habits
c::;, &. . On
vehicles that are either dr iven mostly in stop­
and-go city traffic or are driven hard, the
brake pads should be checked by your author­
ized Audi dea ler more often than specified in
the Warranty
& Maintenance booklet. Failure
to have your brake pads inspected can result
in reduced brake performance.
On steep slopes, you should use the braking
effect of the engine. This way, you prevent un­
necessary wear on the brake system. If you
must use your brakes, do not hold the brakes
down continuously. Pump the brakes at inter­
vals .
Operating noise
Noises may occur when braking depending on
the speed, braking force and outside condi­
tions such as temperature and humidity.
Due to the nature of the materia ls used in ce­
ramic brake rotors*, noises may become more
apparent at low speeds. .,..

Effect of w ate r and ro ad sa lt
In certain situa tions, for example after driving
through water, in heavy rain, after overnight
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 wit h 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 w ithout the
driver noticing and provides for better brake response time under wet condit ions.
The effectiveness of the brakes can be reduced
when the vehicle is dr iven o n a salt-covered
road and the brakes are not used . Likewise,
you clean
off accumulated sa lt coating from
brake discs and pads with a few caut ious ap­
p lications of the brake¢&. -
Due to their surface characteristics, ceram ic
brake roto rs* absorb mo isture in such condi­
tions. This can cause a temporary reduction in
b rak ing fo rce compared to d ry brakes. You can
compensate for this by pressing the brake pedal harder .
Corrosion
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
on ly for short t rips with little use of the
brakes.
I f t he b rakes are not used frequently, or if co r­
rosion has formed on the dis cs, it is advisable
to clean
off the pads and discs by brak ing
firm ly a few times from a moderately high
speed ¢.&. .
Faults in the brake system
If you should notice a sudden increase in
b rake peda l travel, then o ne of the two bra ke
circuits may have failed~ .&..
Int ellig ent technolog y 201
Low br ake fluid level
Malfunctions can occu r in the bra ke system if
the b rake fluid level is too low. The brake fluid
level is monitored electronica lly.
Brake lining wear status
B rake lining wear may be checked by visual in­
spe ct ion of the condition of the brake pads
through the open ings in the wheel. If neces­
sary, the whee l may be removed for this in­
spection
r=;, page 2 7 3, 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 cause an accident!
- Before descend ing 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 t he pedal down too
long o r too often. Th is could cause the
brakes to get hot and diminish braking
efficiency .
- Do not "ride the brakes" by rest ing you r
foo t on the pedal when you do not intend
to b rake . This may cause the brakes to
overheat, premature wear and increased
stopping distance.
- Under certain climatic and operating
conditions such as passing thro ugh wa­
ter, dr iv ing 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, lin ings,
discs and drums . Carefully app ly brakes
for a test. Brakes w ill dry and ice coat­
ings w ill be cleaned
off after a few care­
fu l brake applicat ions.
- Driving for an extended period of time on
salt- cove red 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.

202 Intellig ent technol ogy
- If you damage the fro nt 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 creased stopp ing distance. Avoid driv ing
the vehicle and have it towed to the near­ est Aud i dea ler or qualified workshop .
Brake booster
The brake booster adds extra braking power .
The brake booster works with vacuum pres­
sure which is created only when the engine is
running ¢& .
& WARNING
-Never let the vehicle ro ll to a stop w ith
the engine shut off.
- If the brake booster is not work ing, for
example when towing your vehicle, 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
system senses the road speed and e lectroni­
cally adjusts powe r ass istance to p rov ide com ­
fortable and sa fe stee ring response exactly
matc hed to the ve hicle speed .
Power steering w il l not work if the eng ine is
off . As a result, the steering whee l w ill be hard
to turn.
The power steering fluid level is chec ked dur­
ing the scheduled ma intenance serv ices.
(D Note
If there is an e lectronic malfunction, ser­
votronic
will still function like a conven­
tiona l power steering system, providing a
constant steering support force that is no
l onger proportionate to the vehicle speed.
This is most not iceable when t urning the
steering wheel at low speeds (for example
when pa rking), - more effort w ill be re­
q uired than us ual.
- Be aware of the diffe rent than usual
steering response and adjust your steer­
ing force acco rding ly.
- Have the problem checked and set right
by an A udi dealer as soon as poss ible.
(D Tips
- When the eng ine is running, never ho ld
the stee ring wheel turned all the way to
the rig ht or to the left fo r longer than 15
seconds. The powe r stee ring pump will
overheat the hydraulic fluid i f yo u keep
holding the stee ring wheel turned all the
way. This is likely to damage the power steering system.
- If the powe r steering system sho uld fai l
entire ly, or if the engine is not runn ing
(for example, wh ile be ing towed), you
w ill still be able to stee r the veh icle.
However,
considerably more effort will
be requi red to do so.
- If the power steering system should
have a leak, or is not functioning proper­
ly, contact your author ized Audi dealer
immed iately.
- The power steer ing system req uires a
specially fo rmu lated hyd raulic fluid. The
powe r stee ring fluid reservoir is located
in the engine comp art ment¢
page 234.
T he cor rect fluid level in the reservoir is
impo rtant fo r proper functioning of the
powe r stee ring .

208 Driving and en vir onm ent
Driving through water
on roads
Note the following to avoid vehicle damage
when driving through water, for example on
flooded roads:
- The water must not be any higher than the
bottom of the vehicle body.
- Do not drive faster than wa lking speed.
A 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
sto re the full braking effect.
@) Note
- Vehicle components such as the eng ine,
transmission, suspension or electr ical
system can be severely damaged by driv­ i ng th rough water.
- Always switc h off the Start-Stop-System
when driving through water~
page 87.
(1) 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 switch the engine off when driving
through water .
- Keep in mind that oncoming vehicles
may create waves that raise the water
level and make it too deep for your vehi­
cle to drive th rough safely.
- Avoid dr iving through salt water because
i t can cause corrosion.
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely
depend on three factors:
- your personal driving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
t ion w ill give you some tips on how you can
help the env ironment and your pocketbook.
@ Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not corre­
spond to your actual consumption on the
road, which will vary depending upon vehi ­
cle load and speed, road and weather con ­
ditions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most fuel when they a re ac­
ce lerating. If you anticipate what is going to
happen next, you will need to brake less and,
t hu s, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

Trailer towing Driving with a trailer
General information
Your Audi was designed primarily for passen­
ger transportation .
If you plan to tow a trai ler, p lease remember
that the addit ional load will affect durab ility,
economy and performance .
Trailer towing not on ly places more stress on
the vehicle, it also calls for more concentra­
tion from the driver.
F or this reason, a lways fo llow the operating
and d riving instr uctions provided and use
common sense.
(D Note
If you are going to tow a trai ler, you must
activate the trailer operat ion mode
~ page 211, Operating instructions.
Technical requirements
Trailer hitch
Use a weight-carrying hitc h co nforming to the
gross trailer we ight. The hitch must be suita­
b le for your veh icle and trailer and must be
mounted secure ly on the veh icle's chassis at a
technically sound location . Use only a trailer
hi tch wit h a removab le ball moun t. A lways
check with t he trail er hitch ma nufactur er to
make sure tha t you are using the corre ct
hi tch.
Do not use a bumper hitch.
The hitc h must be installed in such a way that
i t does not interfere with the impac t-absorb­
i ng bumpe r sys tem. No mod ifica tio ns should
be made to the vehicle exh aust a nd brake sys­
tems . From time to time, check that a ll hitch
mo unt ing bolts remain securely fastened.
W hen you are not towing a trail er, remove the
traile r hitch ball mount. Th is prevents the
hi tch from causing damage sho uld your ve hi­
cle be str uck from behind ¢& .
Trailer towin g 211
Trailer brakes
If your trailer is equippe d wi th a br akin g sys ­
tem, check to be s ure that i t conforms to all
r egulations .
T he trailer hy draul ic brak e sys tem mus t not be
direc tly connec ted to the vehi cle' s h ydraulic

Safety chains
Always use safety chains between your veh icle
and the tra ile r.
Trailer lights
Trai ler lights must meet all regu lations. Be
su re to check with your Audi dealer for cor rect
wir ing, swi tches and relays .
Mirrors
If you are unable to see the traffic behind you
us ing the reg ular o utside mirrors, then you
must insta ll extended mirrors. It is imp ortant
that you
always have clea r v is ion to the rear.
A WARNING ...__ -
Afte r removing the trailer hitch, do not

Engine cooling sy stem
Towing a tra iler makes the eng ine work hard­
er . It is important that the cooling system's
performance is up to the addit ional load .
Make sure that the cooling system has eno ugh
flu id.
Tir e pressure
When tow ing a tra iler, inflate the t ires of your
vehicle to the co ld tire pressure listed under
" Full load " on the label loca ted o n the dr iver's
side B-pillar (v is ible when the door is open).
I nflate trailer tires to tra iler and tire manufac­
turers' specifications.
Lights
Check to make sure both veh icle and trailer
l ights are wor king p roperly.
Safe ty chain s
Be sure tra iler safety cha ins are properly con­
nected from the trailer to the hitch on the ve ­
h icle . Leave enough slack in the chains to per­
mit turning corners . When you install safety
cha ins, make su re they w ill not drag on the
road when yo u are driving.
The chains shou ld cross under the tra iler
tongue to prevent it from dropping in case of
separat ion from the hitch .
Adjusting the Audi drive select
Make sure the vehicle is on a level surface be­
for e

(D Note
-Changes in temperature or load can af­
fect the height of the vehicle .
- Always select auto or comfort mode .
Otherw ise, the tongue load specified for
your vehicle will no longer be applicable.
Driving instructions
Driving with a trailer always requires extra
core and consideration.
T o obtain the best possible hand ling of vehicle
and trailer, please note the fo llowing:
.. Do not tow a loaded t railer when you r ca r it­
self is not loaded .
.. Be especially carefu l when passing other
vehicles.
.. Observe speed limits.
.. Do not drive at the maximum permissible
speed .
.. Always apply brakes early .
.. Monitor the temperature gauge .
Weight di stribut ion
T owing a loaded trailer with an empty car re ­
su lts in a highly unstable d istribution of
weight. If this cannot be avoided, drive at very
l ow 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 keep ing the trailer as light as possi­
ble under the ci rcumstances. Whenever poss i­
ble , transfer some ca rgo to the luggage com ­
partment of the tow vehicle while obse rv ing
tong ue load requi rements and vehicle load ing
considerations .
Speed
The higher the speed, the more d ifficu lt it be­
comes fo r the driver to cont rol the rig. Do not
1111>

drive at the maximum permissible speed. Re­
duce your speed even more if load, weather or
wind condit ions are unfavorable -part icularly
when going downhill.
Reduce vehicle speed
immediatel y if the trail­
er shows the slightest sign of swaying .
Do not
try to stop the swaying by accelerating.
Observe speed limits . In some areas, speeds
for vehicles towing trailers are lower than for
regular vehicles .
A lways app ly brakes early. When driving
downhill, shift into a lower gear to use the en­
gine braking effect to slow the vehicle . Use of
the brakes a lone can cause them to overheat
and fail.
Coolant temperature
The coolant temperature gauge c:> page 10
must be observed carefully. The coo lant tem­
perature can increase if you drive on long in ­
clines in a low gear at high engine speeds. Re­
duce your speed immed iate ly if the L EDs in
the top part of the display turn on.
F or more information about indicator lights,
refer to. ~

A WARNING
Anyone not properly restrained in a mov­
ing vehicle is at a much greater risk in an
accident . Never let anyone r ide in your car
who is not properly wear ing the restra ints
provided by Aud i.
Trailer towing tips
Important to know
Your veh icle hand les different ly when tow ing
-
a trailer because of the addit ional weight and
d ifferent weight distribution . Safety, perform­
ance and economy will greatly depend on how
carefully you load your trailer and operate
your ng .
Before you actually tow your trailer, practice
turning, stopping and backing up in an area
away from traffic. Keep practicing until you
Trailer towing 213
have become completely familiar with the way
your vehicle-trai ler combination behaves and
responds.
Backing up is difficult and requires practice .
Backing up with a t railer generally requires
steering action opposite to that when backing
up your vehicle without a tra iler.
Maintain a greater distance between your ve­
hicle and the one in front of you . You wi ll need
more room to stop. To compensate for the
trailer, you w ill need a larger than normal
turning radius.
When passing, remembe r that you cannot ac­
ce lerate as fast as you norma lly would be­
cause of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for your trailer before chang­
ing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes.
(D Tips
- Do not tow a trailer during the break-in
period of your vehicle.
- If you tow a trailer, your Audi may re ­
quire more frequent maintenance due to
the extra load
c:> page 296.
Parking on a slope
Do not park on a slope with a trailer. If it can­
not be avoided, do so only a~er doing the fol­
lowing:
When parking:
.,. App ly the foot brake.
.,. Have someone p lace chocks under both the
vehicle and the trailer wheels .
.,. With chocks in place, slowly release the
brakes until the wheel chocks absorb the
load.
.,. Turn the wheels towards the curb .
.,. Apply the parking brake .
.,. Select the P selector lever posit ion .
When restarting after parking:
.,. Apply the foot brake.

Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle
body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .
