Braking
What affects braking efficiency?
New brake pads
During the first 250 miles (400 km), new brake
pads do not possess the ir full braking effect, they
have to be "broken in" first¢.&. . You can com­
pensate for this slightly reduced braking power
by push ing harder on the brake pedal. Avoid
h eavy braking loads during the break-in period .
Operating conditions and driving habits
The brakes on today's automobiles are still sub­
ject to wear , depend ing largely on operating con­
d itions and dr iving habits ¢.&. . On veh icles that
are e ither dr iven most ly in stop-and-go city traf­
fic or are driven hard, the brake pads should be
checked by your authorized Audi deale r more of­
ten than specified in the
Warranty & Mainte­
nance booklet.
F ailure to have your brake pads inspected can result
in reduced brake perform­
ance.
On steep slopes, you should use the braking ef­
fect of the engine. This way, you prevent un nec­
essa ry wea r on the brake system. If you must use
you r brakes, do not hold the brakes down contin­
u ous ly. Pump the brakes at intervals.
Operating noise
Noises may occur when braking depending on the
speed, bra king fo rce and outside conditions such
as temperature and humidity.
Effect of water and road salt
In certain situations, for example after driving
through water, in heavy rain, after overn ight con­
densation or afte r wash ing your car, the brak ing
effect can be reduced by moisture or ic e on the
brake rotors and brake pads. The brakes must be
dried f irst with a few careful brake applications .
At h igher speeds and w ith the windshield wipers
turned on, the brake pads press against the brak e
rotors for a short amount of time. This occurs at
regular intervals without the driver noticing and
provides for better brake response t ime under
wet conditions.
T he effectiveness of the brakes can be reduced
when the vehicle is driven on a sa lt-covered road
and the brakes are not used . Likewise, yo u clean
off accum ulated salt coating from brake discs
and pads with a few cautious applications of the
brake¢ .&..
Corrosion
There may be a tendency fo r dirt to build up on
the brake pads and corrosion to form on the discs .,..
189

Intelligent Technology
if the car is not driven regularly or only for short
trips with little use of the brakes.
If the brakes are not used frequently , or if corro­
sion 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 of 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 lectronically .
Brake booster
The brake booster works with vacuum pressure
which is created only 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 openings in the wheel. If necessary,
the wheel may be removed for this inspection
c;> page 253, Replacing wheels .
A WARNING
-New brake pads don't have the best stop­
ping power and must be "broken- in" dur ing
the initial 250 miles (400 km) . You can
compensate for this by pressing the brake
pedal more firmly. This also applies later
when new pads are installed.
- 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 descending a steep grade, reduce
speed and shift transmission 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 brakes to get
hot and diminish brak ing efficiency.
190
- Do not "ride the brakes" 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.
- Under certain climatic and operating condi­
tions such as passing through water, driving in heavy rain or after washing the vehicle,
the effectiveness of the brakes can be re­
duced. In winter, ice can accumulate on the
brake pads, linings, discs and drums. Care­
fully apply brakes for a test. Brakes will dry
and ice coatings will be cleaned off after a
few careful brake applications .
- Driving for an extended period of time on
salt-covered roads without using your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from brake discs and pads with a few careful
brake applications.
- If you damage the front spoiler, or if you in­
stall a different spoiler, be sure the air flow
to the front brakes is not obstructed. Other­
wise the brake system could overheat reduc­
ing the effectiveness of the entire brake sys­
tem.
- Fa ilure 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 Audi dealer
or qualified workshop.
- Never let the vehicle roll to a stop with the
engine shut off.
- If the brake booster is not working, the
brake pedal must be pressed considerably
harder to make up for the lack of booster
assistance.
Electromechanical
steering, dynamic
steering
The electromechanical steering supports the
driver's steering movements.
Power steering adapts electronically based on
the vehicle speed.

Intelligent Technology
All wheel drive (quattro)
Applies to vehicles: with all wheel drive
In all wheel drive, all four wheels are powered.
General informat ion
In all whee l dr ive, the dr iving power is div ided be­
tween all fou r wheels . This happens automatical­
ly depending on yo ur driving behavior as we ll as
the cur rent road conditions . Refer to ¢ page 187,
E lectronic Stabilization Control (ESC).
A center d ifferential d istribu tes the driving power
variab ly to the front and rear axle. It works to­
gether with selective whee l torque contro l, w hich
activates when driving through curves
¢ page 188. With the sport d ifferential*, power
distribution to the rear wheels is variable and can
be adjusted with drive select¢ page 100 .
The all wheel drive concept is designed for high
engine power. Your vehicle is except ionally pow­
erfu l and has excellent driv ing characteristics
both under normal driving conditions and on
snow and ice . Always read and follow safety pre­
cautions ¢
..1:)..
Winter tires
By using all wheel dr ive, your veh icle has good
forward motion with standard tires in w inter con­
ditions. However, in w inter we recommend using
winter or all seaso n tires on all four wheels, be­
ca use this will improve the brak ing effect.
Snow chains
If there are snow chain laws, snow cha ins must
also be used on veh icles w ith all wheel dr ive
¢ page 246 , Snow chains .
Replacing tires
For vehicles with a ll wheel drive, on ly wheels with
the same roll ing circumference should be used.
Avo id whee ls with different tread depths

Offroad vehicle?
Your Audi is not an offroad vehicle - there is not
enough ground clearance. For this reason, avoid
difficult terrain. ..,.

Intelligent Technology
& WARNING
- Also, in vehicles with all wheel drive, adapt
your driv ing style to the curre nt road and
traffic conditions. Do not let the increased safety provided tempt you into tak ing risks,
because th is increases the r is k of an acci­
dent.
- T he brak ing ability of your vehicle is limited
to the tra ction of the wheels. In this way, it
is not diffe rent from a two whee l dr ive ve hi­
cl e. Do not be tempted to accelerate to a
high speed when the road is slippery this in­
c reases the risk of an acc ident.
- Note that on wet stree ts, the front wheels
can "hyd roplane" if d riving at speeds that
are too high. Unlike front whee l drive
vehicles, the eng ine does not rev higher sud­
denly when the vehicle begins hydroplaning.
For this reason, pay attention to the road
condit ions regardless o f you r sp eed to re­
duce the r is k of an accident.
Energy management
The starting ability is optimized
The energy managemen t system manages the
electrical energy distribution and optimizes the
availability of electrical energy for starting the
engine.
When a ve hicle wit h a co nven tional energy sys ­
tem is not driven for a long time, the batte ry is
d rained by equipment (for example t he immobi l­
izer) . In certain circumstances, there could may
not be eno ugh energy to start the engine.
Your vehicle is equipped with a n intelligent ener ­
gy management system for distr ibuting e lectric i­
ty. This s ignificantly improves the starting ability
and increases the b attery life.
The energy management system Is made up of
battery diagno sis , idling current management
and dynamic energy management .
Battery diagnosis
T he batte ry d iagnosis de term ines t he b att ery
ch arge level. The senso rs detect the battery, the
battery current, and the battery temperature.
192
The c urren t cha rge level and the performance of
the battery are determined based on this .
Idling current management
The idling current manageme nt decreases the
energy used while parked. Wi th the engine
swi tched off , it m anages t he energy dis trib ution
to the d ifferent e lectrica l components. Date from
batte ry diagnosis is taken into acco unt for this.
De pend ing on the b atte ry charge level, ele ctrical
equipmen t is switched off one item a fter the o th ­
er, to preven t the bat tery from draining and to
retain the starting ability .
Dynamic energy management
While driv ing , dynam ic energy manageme nt dis ­
t ribu tes the appr opr iate amo unt of energy to the
e lectri ca l eq uipment. It contro ls the battery
charge level so that more energy is not used then
is being generated in order to maintain an opti­
mal battery charge level.
(D Tips
- Ener gy management cannot overcome the
laws of p hysics . Note that the charge level
and length of the battery life are limited.
- Whe n the sta rting ability is endangered, the

What you should know
Maintaining the starting ability is the highest
priority.
A lo t of st ress is placed on the b attery when dr iv­
i ng sho rt distances, in t raff ic, and at cold times
of the year . A lot of energy is used but litt le is
generated. It is also critical when the engine is
not running but e lectr ica l equipment is sw itched
on. In th is case, energy is used but none is gener­
ated.
In sit uat ions like th is, ene rgy management w ill
active ly regulated the dis trib ution of energy.
Long periods without use
I f you do not drive yo ur vehicle for sever al days o r
weeks, e lectrica l equipment is gradua lly sca le d
back or sw itched off. This reduces ene rgy use and ..,.

braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Air suspension*
When driving with a tra ile r, activate the trailer
mode of the air suspension. Switch the air sus ­
pension trailer mode on when you are towing a
trailer. This will limit the regulation by the air
suspension while driving. Select in the MMI :
ICARI function button > (Car)* systems control
button>
Vehicle settings> Air susp.: towing>
On.
Coolant temperature
The coolant temperature gauge¢ page 10 must
be observed carefully . The coolant temperature
can increase if you drive on long inclines in a low
gear at high engine speeds. Reduce your speed immediately if the LEDs in the top part of the dis­
play turn on .

fer to. ¢
page 15.
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 p roperly wearing the restraints p rovided
by Audi.
Trailer mode notes
Important to know -
Your vehicle handles differently when towing a
trailer because of the additional weight and dif­
ferent weight distribution. Safety, performance
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 traff ic. Keep practicing until you have be­
come comp letely fami liar with the way your vehi­
cle-trailer comb inat ion behaves and responds.
Backing up is difficult and requires practice.
Backing up with a trailer generally requires steer-
Trailer mode
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 passing, remember that you cannot accel­
erate as fast as you normally wo uld because of
the added load . Make sure you have enough room
to pass. After passing, allow p lenty of room for
your trailer before changing lanes again .
Avo id jerky starts, sharp turns or rapid lane
changes.
(D Tips
- Do not tow a trailer during the break-in peri­
od of your veh icle.
-If you tow a trailer, your Audi may require
more frequent maintenance due to the ex­
tra load ¢
page 2 73.
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 .
" Have someone place chocks under both the ve­
hicle and the trailer wheels.
"W ith chocks in place, slowly release the brakes
until the wheel chocks absorb the load.
" Turn the whee ls towards the curb.
" App ly the parking brake.
" Select the P selector lever position.
When restarting after parking:
"App ly the foot brake.
" Start the engine .
"S elect the D/S se lector lever position.
" 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 se lector lever of the automat­
ic transm ission to P before applying the park­
ing brake and before block ing the wheels, you
may have to use more force later to move the
lever out of the P position .

Care and cleaning
-To reduce the risk of cuts, protect yourself
from sharp metal components when was h­
ing the underbody or the inside of the wheel
housings .
- After washing the vehicle, the braking effect
may be delayed due to mo isture on the
brake rotors or ice in the winter . The brakes
must be d ried first w ith a few careful b rake
applications.
(D Note
- If you wash the vehicle in an automatic car
wash, you must fold the exte rior m irrors in
to reduce the risk of damage to the mirrors.
Power folding exte rior m irrors* must on ly
be fo lded in and out us ing the powe r folding
f u nct ion.
- To p revent paint damage , do not wash the
vehicle in di rect sunlight.
- To reduce the risk of damage to the surface,
do not use insec t remov ing sponges, kit chen
sponges or similar items. - Matte finish painted vehicle components:
-To reduce the r isk of damage to the sur-
face, do not use polis hing agents or hard
wax.
- Never use protective wax. It can destroy
the matte finish effect .
- Do not place any stickers or magnetic
signs on vehicle parts painted with matte
finish paint. The paint could be damaged
when the stickers or magnets are re­
moved.
@ For the sake of the environment
Only wash t he ve hicle in facilities spec ially de­
signed for that pu rpose . This will reduce the
r isk of dirty wate r contaminated with o il from
ente ring the sewe r system.

Wheels and Tires
General information
.,.Check your tires regularly for
damage (punctures, cuts, cracks
and bulges). Remove foreign ob­
jects from the tire tread.
.,. If driving over curbs or similar
obstacles, drive slowly and ap­
proach the curb at an angle.
.,.Have faulty tires or rims re­
placed immediately.
"'Protect your tires from oil,
grease and fuel.
.,.M ark tires before removing
them so that the same running
direction can be maintained if
they are reinstalled.
"'Lay tires flat when storing and
store them in a cool, dry location
with as little exposure to light as
possible.
(D Note
-Please note that summer and
winter tires are designed for
the conditions that are typical in those seasons. Audi recom­
mends using winter tires dur­
ing the winter months. Low
temperatures significantly de­ crease the elasticity of summ­
er tires, which affects traction
Wheels
and braking ability. If summer
tires are used in very cold
temperatures, cracks can form
on the tread bars, resulting in
permanent tire damage that
can cause loud driving noise
and unbalanced tires.
-Burnished, polished or
chromed rims must not be
used in winter driving condi­
tions. The surface of the rims
does not have sufficient corro­
sion protection for this and
could be permanently dam­ aged by road salt or similar
substances.
