In extreme cases, EDL automatically switches off
to help keep the brake on the braked wheel from
overheating. EDL w ill switch on aga in automati­

Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque .
In vehicles with dynamic steering*, ESC also
helps to stabilize the steering in critical situa­
tions.
Electronic interaxle differential lock*/
selective wheel torque control*
The electronic interaxle differential lock (front
wheel drive) or the selective wheel torque control
(all wheel drive) operates when driving through
curves . The front wheel on the inside of the curve
or both wheels on the inside of the curve are
braked selectively as needed. This allows more
precise driving in curves. The applicable system
may not activate when driving in wet or snowy
conditions .
_&, WARNING
- The ESC and its integrated systems cannot
overcome the laws of phys ics. Th is is espe ­
cially important on slippery or wet roads.
If
the systems begin acting to stabilize your

veh icle, you should immediately change
your 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 vehicle control, collision and seri­
ous personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of losing con­
trol 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 . The ESC and its
integrated systems cannot always prevent
collisions -there is still a risk of accidents!
- 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 always help to reduce
the risk of loss of vehicle control.
{!) Tips
- ABS and ASR only work correctly when all
four wheels are equipped with identical
tires. Different tire sizes can lead to a reduc­
tion in engine power.
- You may hear noises when the systems de­
scribed are working .
ESC turns on automatically when you start the engine.

Braking
What affects braking efficiency?
New brake pads
D ur ing the first 250 miles (400 km) , new brake
pads do not possess their full b raking effe ct, they
have to be "b roken in" first ¢,&. . You can com­
pensa te for th is slightly reduced b raking power
by p ushing harder on the brake pedal. Avo id
heavy braking loads dur ing the break-in period .
Operating conditions and driving habits
The brakes on today's automobi les are s till sub­
je ct to wear, depending large ly on operating con­
dit ions and driving habits ¢.&. . On vehi cles that
a re either driven mostly i n stop-and-go city traf­
fic or are drive n hard, the b rake pads sho uld be
checked by your authorized A udi dealer more of­
ten than specified in the
Wa rrant y & Mainte ­
nance book let .
Failure to have your brake pads
i nspected can result in reduced brake perform ­
ance .
On steep slopes, you should use the brak ing ef­
fect of the engine . Th is way, you prevent unnec­
essary wear on the brake system . If you must use
your brakes, do not ho ld the bra kes down contin­
u ously. P ump the bra kes at inte rvals.

Noises may occur when braking depend ing on the
speed, braking force and outside conditions such
as temperature and humidity.
Eff ect of wat er and road salt
In ce rtain situations, for example after dr iving
through water, in heavy ra in, afte r ove rnig ht con­
densat io n 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 highe r speeds and with the windsh ie ld wipers
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 better brake response time under
wet conditions.
The effectiveness of the brakes can be reduced
when the vehicle is driven on a salt-covered road and the brakes are not used . Likewise, you clean
off accumu lated salt coating from brake discs
and pads with a few cautious applications of the
brake ~,&. .
Cor ro sion
There may be a tendency for dirt to b uild up on
the brake pads and corros ion to form on the discs
if the car is not driven regularly or only for short
tr ips with little use of the brakes .
If the brakes are not used frequently, or if corro­
sion has formed on the discs, it is adv isable to
clean off the pads and discs by braking firmly a
few t imes from a moderately high speed

_8 WARNING "'---
-New brake pads don't have the best stop­
ping power and m ust be "broken-in" during
the initial 250 miles (400 kilometers). You can compensate for this by p ressing the
brake pedal more firmly . This also app lies
later when new pads are installed.

- You shou ld pe rform braking maneuvers for
the purpose of cleaning the brake system
only i f road condit ions pe rmit . Other road
users m ust not be put at r is k -you may
cause an ac ciden t!
- Before descending a s teep g rade , reduce
speed and sh ift tr ansmi ssion into a lower
gear or lower dr iving range. Do not r ide the
brakes or hold the pedal down too long or
too often. This co uld cause the brakes to get
hot and dimin ish braking eff ic iency.
- Do not "ride the bra kes" by resting your foot
on the pedal when you do not intend to brake. This may cause the brakes to over­
heat, premature wear and increased stop­
ping distance.
- Unde r ce rtain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after wash ing the veh icle,
the effectiveness o f the brakes ca n be re­
duced. In winter, ice can accumu late on the
brake pads, lin ings , d is c s and dr ums . Care­
fu lly apply br akes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful bra ke applications .
- Driving for an extended period of time on
salt -covered roads without using your
brakes can also affect braking eff iciency .

Intelligent Technology
according to t he needs of the individua l compo­
nents. It regu lates consumption , so that more
e lectr ical energy is not being used than is being
generated and ensures an optimal state of
charge for the battery.
(D Tips
- But even energy management cannot neg­
ate the limits of physics . Cons ider that the
power and life of a battery are limited.
- If starting ability is threatened, the indica­
tor light (•) appears ¢
page 16.
What you should know
The highest priority is given to maintaining start­
ing capability.
The batte ry is severely taxed in short-distance
driving, in c ity traffic and d uring the co ld time of
year. Abundant electrical energy is req uired, but
only a little is generated . It is also c rit ica l if the
engine is not runn ing and electrical components
are turned on . In this instance energy is be ing
consumed but none is be ing generated .
It is in precisely t hese situations that you will no­
tice energy management active ly regulat ing the
d istr ibut ion of energy .
Vehicle stands fo r an e xtended period
If you do not drive your vehicle over a period of
several days or weeks, electrical components are
gradually cut back or sw itched off. T his reduces
energy consumption and ma inta ins starting ca­
pab ility over a longer period . Some of the con­
ve nience funct ions may not ope rate, such as the
i n terio r lights or the powe r seat adjustment. The
conven ience f unc tions w ill be available again
when yo u switch on the ign it io n and s tart the en­
g ine.
With the engine turned off
I f you listen to t he radio, fo r example , with the
engine tu rned off o r use other MMI functions,
the batte ry is being discharged.
If start ing capabili ty is jeopardized due to energy
consumpt ion, a message appears in t he M MI dis­
p lay. The message indicates that the system wi ll
176 b
e switched off a utomat ica lly in a moment . If
you wish to continue using the functions, you have to sta rt the eng ine.
With the engine running
Althoug h elec trica l energy is gene rated w hen t he
vehicle is bei ng drive n, the batte ry can become
discharged. This happens mostly when little en ­
ergy is being generated and a great dea l con­
s u med and the battery 's state of charge is not
optimal.
To bring the energy balance back into equilibri ­
u m, consumers whic h require espec ia lly large
amounts of energy are temporar ily cut back or
switched off. Heating systems in particular re­
quire a great dea l of energy. If you notice, for ex­
ample, that the heated seats* o r the heated rear
window are not heati ng, they have bee n tempo­
r arily cut back o r switched off . These systems will
be available again as soon as the ene rgy balance
has been res tored.
You w ill also no tice that eng ine idle speed has
been increased slig htly . T his is no rma l and not a
ca use for concer n. By in cr easi ng engine idle
speed t he ad ditional energy required is gene rat­
ed and the battery is charged.

Breaking in
New engine
The engine needs to be run-in during the first
1,000 miles (1,500 km).
For the first 600 miles (1 ,000 kilometer s):
"' Do not use full throttle .
"' Do not drive at engine speeds that are more
than
2/3 of the max imum permitted RPM .
From 600 to 1,000 miles (1 ,000 to 1 ,500
kilometers):
"' Speeds can gradually be increased to the maxi­
mum pe rm issib le road or engine speed .
During and after break-in pe riod
"' Do not rev the engine up to high speeds when it
is cold. This applies whether the transmission is
in N (Neutral) or in gear .
After the break-in period
"'Do not exceed maximum engine speed under

During the first few hours of driving, the eng ine's
internal friction is higher than later when all the

Economical and environ­
mentally-friendly driving
General
Your personal style of driving will determine the
economy of your vehicle, as well as exhaust and
noise levels.
F ue l economy, environmenta l impact, and we ar
on your engine, brakes and tires la rgely depend
on three factors :
- you r persona l dr iving sty le
- operating conditions
- technical lim itations
If you anticipate what you need to do next and
drive economically, you can eas ily cut your fue l
consumption by
10-15 percen t. This section will
g ive you some tips on how you can help the envi ­
ronment and yo ur pocketbook .
(!) Tips
The consumpt ion estimates as published by
ENVIRONMENTAL PROTECTION AGENCY (EPA) and Transport Canada may not cor re­
spond to your actual consumption on the
road, which will va ry depending upon vehicle
load and speed, road and wea ther condi tions,
t rip length, etc.
Drive smoothly and keep a lookout ahead
Vehicles use the most fuel when they are acceler­
ating.
" Avoid unnecessary accelerating a nd braking .
Veh icles use the most fuel when they are acceler ­
ating . If you anticipate what is going to happen
next , you will need to brake less and, thus, accel­
e rate less . let the vehicle coast wheneve r possi ­
b le -fo r example when yo u see that the next traf­
fic light is red .
Driving and the envir onment
Avoid full throttle
Driving at moderate speeds saves fuel and im­
proves your mileage .
"Try and keep well below your car 's maximum
speed.
Acce lerating gently reduces fuel consumption,
engine wear, and does not disturb the environ­
ment.
Fuel consumption, exhaust emissions and engine
noise increase disproport ionately 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 cond itions permit .
Reducing unnecessary idling
Even when your car is jus t idling it burns up fuel.
" Shut the eng ine off when you are not driving
the vehicle.
" Do not warm up the vehicle by lett ing the en-
gine run
at idle.
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at railroad cross ings, or at traff ic lights that have long waits
on red . Turning the engine off for just
30 -40 sec ­
onds saves more f uel than is burned starting the
. . engine again.
It takes a long time for the eng ine to warm up
fully when it is running at idle . However, wear
and noxious emissions are especially h igh when
the engine is warming up . So yo u should dr ive
away as soon as you start the eng ine and avoid
runn ing at high rpms w hile the engine is st ill
warming up .
(D Note
Do not leave eng ine idling unattended after
s tart ing. If wa rning lights sho uld come on to
i ndicate improper operation, they would go
unheeded . Extended idling also prod uces
heat, which could resu lt in overheating or
other damage to the vehicle or other proper­
ty.

Trailer mode
Tire pressure
When towing a trailer, inflate the tires of you r
veh icle to the cold tire pressure listed under "Fu ll
load" on the label located on the driver's side B ­
pillar (visib le when the door is open) . Inflate
trai ler tires to trailer and tire manufacturers'
specifications.
Lights
The headlight settings should be checked with
the trailer attached before driving off. Check to
make sure both vehicle and trailer lights are
working properly .
Safety chains
Be sur e trailer safety chains are properly connect­
ed from the trai ler to the hitch on the vehicle .
Leave enough slack in the chains to permit turn­
ing corners . When you install safety chains, make
sure they w ill not drag on the road when you are
driving.
The chains shou ld cross under the trailer tongue
to prevent it from dropping in case of separation
from the hitch.
Driving instructions
Driving with a trailer always requires extra care
and consideration.
To obtain the best possible handling of vehicle
and trailer, please note the fo llowing :
.. Do not tow a loaded trailer when your car itself
is not load ed .
.. Be especia lly 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 distribution
Towing a loaded trailer with an empty car resu lts
in a high ly unstable distribution of weight. If this
cannot be avo ided, drive at very low speeds only
to avoid the risk of losing steering control.
182
A "balanced" rig is easier to operate and control.
This means that the tow vehicle shou ld be loaded
to the extent possible and permissib le, wh ile
keeping the trailer as light as poss ible under the
c ir cumstances . Whenever possible, transfer
some cargo to the luggage compartment of the
tow veh icle while observing tongue load require­
ments and vehicle load ing considerations .
Speed
The higher the speed, the more difficult it be­
comes for the driver to control the r ig. Do not
drive at the maximum permissible speed. Reduce
your speed even more if load, weather or wind
cond it ion s are unfavorab le -particularly when
go ing downh ill.
Reduce vehicle speed
immediately if the trailer
shows the slightest sign of sway ing .
Do not try
to stop the swaying by accelerating.
Observe speed limits. In some areas, speeds for
vehicles towing tra ilers are lower than for regular
vehicles.
Always apply brakes early. When driving down­
hill, shift into a lower gear to use the engine
braking effect to slow the vehicle . Use of the
brakes alone can cause them to overheat and fail.
Coolant tempe rature
The coolant temperature gauge c::> page 10 must
be observed carefully.
If the needle moves close
to the upper end of the scale, reduce speed im­
med iately and/or turn off the a ir cond itioner .
If the coolant temperature warning light . in
the instrument cluster starts flashing, pull off
the road, stop and let the engine
idle for about
two m inutes to prevent heat build-up .
A WARNING
Anyone not properly restrained in a moving
vehicle is at a much greater risk in an acci­
dent. Never let anyone ride in your car who is
not properly wearing the restraints provided
by Audi.

Trailer mode notes
Important to know
Your vehicle handles different ly when tow ing a
trailer because of the additional weight and d if­
ferent weight distr ibution. Safety, perfo rmance
and economy will greatly depend on how careful­
ly you load your trailer and operate your rig .
Before you actually tow your trailer, practice
turning, stopping and backing up in an area away
from traffic. Keep practicing until you have be­
come completely familiar with the way your vehi­
cle-trailer combination behaves and responds.
Backing up is difficult and requires pract ice.
Backing up with a trailer generally requires steer­
ing action opposite to that when backing up your
vehicle without a trailer.
Maintain a greater distance between your vehicle
and the one in front of you. You will need more
room to stop. To compensate for the trailer, you
will need a larger than normal turning radius.
When pass ing, remember that you cannot accel­
erate as fast as you normally would because of
the added load. Make sure you have enough room
to pass. After passing, allow plenty of room for
your trai ler before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your vehicle.
- If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load
c::> page 244.
Parking on a slope
Do not pork on a slope with a trailer. If it cannot
be avoided, do so only ofter doing the following:
When parking:
;::; .. Apply the foot brake.
0 ~ .. Have someone place chocks under both the ve-
~ hicle and the trailer wheels. Lil ,...., v:, ,....,
Trailer mode
.. 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.
.. Place an automatic transmission* in P, respec­
tively a manual transmission in first or reverse
gear .
When restarting after parking:
.. App ly the foot brake.
.. Start the engine .
.. Move the selector lever to D/S, respectively a
manual transmission in first gear .
.. Release the parking brake and slowly pull out
and away from the wheel chocks.
.. Stop and have someone retrieve the wheel
chocks.
(D Tips
If you move the selector leve r of the automat­
ic transmission* to P before applying the
parking brake and before blocking the wheels,
you may have to use more force later to move
the lever out of the P position.

Care and cleaning
Care and cleaning
General information
Regular, proper care helps to maintain your vehi­
cle's value.
It can also be a requirement when
submitting warranty claims for corrosion damage
and paint defects on the body.
The necessary care products can be obtained
from your authorized Audi dealer . Read and fol­
low the instructions for use on the packaging.
A WARNING
-Using cleaning and care products incorrectly
can be dangerous to your health.
-Always store cleaning and care products out of reach of children to reduce the risk of poi­
soning .
@ For the sake of the environment
-Preferably use environmentally-friendly
products when buying cleaning agents.
- Do not dispose of leftover cleaning and care
products with household trash.
Car washes
The longer that deposits remain on the vehicle,
the more the surface may be damaged. High
temperatures such as those caused by sunlight
increase the damaging effect.
Before washing, rinse
off heavy deposits with
plenty of water.
Stubborn deposits such as bird droppings or tree
sap are best removed with plenty of water and a
microfiber cloth.
Also , wash the underside of your vehicle once
road sa lt stops being used for the season.
Pressure washers
When washing your vehicles with a pressure
washer, always follow the operating instructions
provided with the pressure washer. This is espe­
cially important in regard to the pressure and
spraying distance . Do not aim the spray directly
at seals on side windows, doors, the hood, the
luggage compartment lid or the sunroof* or at
184 tires,
rubber hoses, insulating material, sensors*
or ca mer a lenses*. Keep a distance of at least
40.64 cm (40 cm).
Do not remove snow and ice with a pressure
washer.
Never use rotary nozzles or high pressure noz­
zles.
The water temperature must not be above 140 °F
(60
°() .
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof* are closed
and the windshield wipers are
off . Follow instruc­
tions from the car wash operator, especially if
there are accessories attached to your vehicle.
If possible, use car washes that do not have
brushes.
Washing by hand
Clean the vehicle starting from the top and work ­
ing down using a soft sponge or cleaning brush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by
hand
To avoid damaging the paint when washing, first
remove dust and large particles from your vehi­
cle. Insects, grease spots and fingerprints are
best removed with a special cleaner for matte
finish paint .
Apply the product using a microfiber cloth. To
avoid damaging the paint surface, do not use too
much pressure.
Rinse the vehicle thoroughly with water. Then
clean using a neutral shampoo and a soft micro­
fiber cloth .
Rinse the vehicle thoroughly again and let it air
dry. Remove any water residue using a sham my.
A WARNING
-
- Only wash the vehicle when the ignition is
off and follow the instructions from the car
