General information
Breaking in
A new vehicle must be broken in, and the break­
in distance should be 1,000 mi les ( 1,500 km). Do
not drive at speeds that w ill exceed
2/3 of the
maximum permitted engine speed
(RPM) for the
first 600 miles (1,000 km) , and avoid full accel­
eration during this period . You may gradually
start increasing the
RPM and the speed between
600 miles (1,000 km) and 1,000 miles (1,500
km).
During the first hours of use, the engine has a
higher internal friction than later on when all
moving parts have settled into place with each
other.
How the vehicle is driven during the first 1,000
miles (1,500 km) also affects the engine quality.
Drive at moderate engine speeds after the initial
break-in per iod, part icularly when running a cold
engine . This will reduce engine wear and improve
the mileage .
Do not drive at too low of an engine speed (rpm).
Shift down if the engine stops running "smooth­
ly" . Extremely high eng ine speeds are automati ­
cally reduced .
Avoid damaging the vehicle
When you are driving on poor roads, or over
curbs, steep ramps, etc., make certain that low­
lying parts such as spoilers and exhaust system
parts do not bottom out and get damaged.
This is especially true for vehicles with low-slung
chassis (sports chassis)* and fully loaded
vehicles.
Driving through water on roads
Note the following to reduce the risk of vehicle
damage when driving through water, for examp le
on flooded roads :
- The wate r must not be any higher than the bot­
tom of the vehicle body .
Driving
- Do not drive faster than walking speed.
A WARNING
After driv ing through water or mud, the effec­
tiveness of the brakes may be reduced due to moisture on the brake rotors and brake pads.
A few careful brake applications should dry
off the brakes .
(D Note
Vehicle components such as the engine,
transmission, suspension or electrical system
can be severely damaged by driving through
water.
(D Tips
- Determine the depth before driving through
water.
- Do not stop the vehicle, drive 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 vehicle to drive
through safely.
- Avoid dr iving through salt water, because
this can cause corrosion.
Economical and environmentally-friendly
driving
T he amount of fuel consumpt ion, the environ­
menta l impact and the wear to the engine,
brakes and tires depends mostly on your driving
style. With an anticipatory and economic driving
style, fuel consumption can be reduced by ap­
proximately 10-15%. The following tips will help
you conserve the environment and your money at
the same time .
Anticipatory driving
A vehicle uses the most fuel when accelerating.
When you drive with anticipation, you do not
need to brake as often and so you accelerate less.
When possible, let your vehicle coast with a
gear
engaged -
for example, when you notice that the
next traff ic light is red . .,,.

Starting on a hill
"' Set the parking brake .
"'With the driving gear selected, press the accel­
erator pedal carefully. The parking brake will
release automatically if your safety belt is fas­
tened .
Under certain circumstances, such as driving in
the mountains, it may be useful to switch tempo­
rarily to the manual shift program in order to
manually adjust the gears to the driving condi­
tions ¢
page 66.
When parking on a level surface, simply place the
selector lever in the P position. On inclines, acti­
vate the parking brake first and then move the selector lever to the P position ¢
page 60. This
prevents the locking mechanism from being
loaded too heavily and will make it easier to
move the selector lever out of the P position .
.8, WARNING
- The vehicle can roll even when the engine is
switched off.
- Unintended vehicle movement can lead to
serious injuries.
- Never leave your vehicle with the engine
running while in gear.
If you must leave
your vehicle when the engine is running, set
the parking brake and move the selector lev­
er to the P position.
- Power is still transferred to the wheels
when the engine is running at idle. To pre­
vent the vehicle from "creeping", you must keep your foot on the brake when the en­
gine is running and the selector lever is in
the D, Sor R position or "tiptronic" mode is
selected.
- Do not inadvertently press the accelerator
pedal when the vehicle is stationary. Other­
wise the vehicle will start to move immedi­ ately, even if the parking brake is set. This
could result in a crash.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is running .
Driving
-Never engage the R or P selector level posi­
tions while driving. It could cause a crash.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with "ti ptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
downhill. Constant braking causes the brakes to overheat and substantially re­
duces braking performance, increases brak­
ing distance or causes complete failure of
the brake system.
- If you must stop on an incline, always hold
the vehicle in place with the foot brake or
parking brake to prevent it from rolling
back .
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. The
mJ indicator light turns on
and a message appears ¢
page 68 when
the clutch is overloaded.
- If the engine must run while you are work­
ing in the engine compartment with the
hood open, make sure a gear is not engag­
ed. The selector lever must be firmly in the
P position and locked in place and the park­
ing brake must be set ¢
page 244. Other­
wise, the vehicle could begin moving when
increasing the engine speed, even with the
parking brake set .
(!) Note
- When stopping on an incline, do not try to
hold the vehicle in place by pressing the ac­
celerator pedal while a driving gear is se­
lected. This can cause the automatic trans­
mission to overheat and can damage it. Set
the parking brake or press the brake pedal
to prevent the vehicle from rolling.
- Allowing the vehicle to roll when the engine
is stopped and the selector lever is in the N
position will damage the automatic trans­
mission because it is not lubricated under
those circumstances.
65

Driving - The transmission can overheat and be dam­
aged under certain driving and traffic condi­
tions such as frequent starts, creeping for a
long time, or stop -and-go traffic. When the
@] or. indicator light turns on, stop the
vehicle at the next opportunity and let the
transmission cool
r=;, page 68 .
-Allowing the vehicle to roll when the engine
is stopped will damage the S tronic trans ­
mission because it is not lubricated
¢ page 294, Towing with a tow truck.
@ Tips
For safety reasons, the parking brake is re­
leased automatically only when the driver's
safety belt is engaged in the buckle.
Hill descent control
The hill descent control system assists the driver
when driving down hills .
Hill descent control is ac tivated when the selec­
tor lever is in the Dor S position and you press
the brake pedal. The transmission automatically
selects a gear that is suitable for the hill. Hill de­
scent control tries to maintain the speed ach­
ieved at the time of braking, within physical and
technical limitations.
If may still be necessary to
adjust the speed with the brakes. Because hill de ­
scent control cannot shift down farther than 3rd
gear, it may be necessary to shift into tiptronic
mode in very steep areas. In this case, shift man­
ually into 1st or 2nd gear in tiptronic mode to
use the engine's braking force to relieve the
brakes .
Hill descent control switches off once the hill lev­
els out or you press the accelerator pedal.
On vehicles with a cruise control system*
¢ page 70, hill descent control is also activated
when the speed is set.
A WARNING
Hill descent control cannot overcome physical
limitations, so it may not be able to maintain
a constant speed under all conditions. Always
be ready to apply the brakes.

Shifting manually (tiptronic mode)
The tiptronic allows the driver to shift the gears
manually .

speed and the distance between your vehi­
cle and other vehicles.
- For safety reasons, cruise control should not
be used in the city, in stop-and-go traffic, on
winding roads and when road conditions are
poor (such as ice, fog, gravel, heavy rain and
hydroplaning), because this increases the
risk of a n accident.
- Switch the cruise control off temporarily
when driving in turning lanes, highway exits
or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal prevents
the cruise control from braking. This is be­
cause pressing the accelerator pedal over­
rides the cruise control system.
- If a brake system malfunction such as over­
heating occurs when the cruise control sys­
tem is switched on, the braking function in
the system may be switched off . The rest of
the cruise control system functions remain
active as long as the
@;\1)~14 (USA models) I
ill (Canada models) indicator light is on.
@ Tips
The brake lights turn on when the brakes are
app lied automatica lly.

fig. 70 up/down to the second level.
.. To increase or decrease the speed quickly ,
hold
the leve r in the 0 / 0 direction until the de­
sired speed is reached .
Overriding the speed
Applies to: veh icles with c ruise control system
You can press the accelerator pedal down to in­
crease your speed, for example if you want to
pass someone. The speed you set earlier wi ll re-
Assist

al.
However, if you are exceeding the stored speed
by a considerable amount for a long time, the
cruise contro l system will temporarily switch off.
The
(ff;ji )~i4 (USA mode ls) Iii (Canada mode ls) in­
dicator light in the instrument cluster turns off
and the stored speed is maintained.
Preselecting the speed
Applies to : vehicles with cruise control system
You can pre-select your desired speed when the
vehicle is stationary.
.. Switch on the ignition.
.. Pull the lever into position (!)
Q page 70,
fig. 70.
.. To increase or decrease the speed, tap the lever
toward

Electronic stabilization
control (ESC)
Description
Electronic Stabilization Control (ESC) supports
driver safety.
It reduces the risk of slipping and
improves driving stability. ESC detects critical sit­
uations such as the vehicle oversteering and un­
dersteering or the wheels are spinning. The vehi­
cle is stabilized by applying the brakes or reduc ­
ing engine torque. When ESC engages, the
G1 in­
dicator light blinks in the instrument cluster.
The following systems are integrated in the ESC:
Anti-lock braking system (ABS)
ABS prevents the wheels from locking when brak­
ing. The vehicle can still be steered even during
hard braking. Apply steady pressure to the brake
pedal. Do not pump the pedal. A pulsing in the
brake pedal indicates that the system is acting to
stabilize the vehicle .
Brake assist system
The brake assist system can decrease braking dis­
tance. It increases braking power when the driver
presses the brake pedal quickly in emergency sit­
uations . You must press and hold the brake pedal
until the dangerous situation is over .
Anti-slip regulation (ASR)
ASR reduces engine power when the drive wheels
begin spinning and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills .
Electronic differential lock (EDL)
EDL applies the brakes to a wheel that starts
spinning and transfers the drive power to the
other driving wheels. This function is not availa­
ble at higher speeds.
In extreme cases, EDL automatically switches
off
to keep the brake on the braked wheel from over­ heating. The vehicle is still working correctly. EDL
will switch on again automatically when condi­
tions have returned to normal.
88 Steering
recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves. The front whee l on the inside of
the curve or both wheels on the inside of the
cu rve are braked selectively as needed. This al­
lows more precise driving in curves. The applica ­
ble system may not activate when driving in wet
or snowy conditions.
A WARNING
- The ESC and its integrated systems cannot
overcome the limits imposed by natural physical laws. This is especially important
on slippery or wet roads. If the systems be­
gin acting to stabilize your vehicle, you
should immediately alter your speed to
match the road and traffic conditions. Do
not let the increased safety provided tempt
you into taking risks. This could increase
your risk of a collision .
- Please note the risk of a collision increases
when driving fast, especially through curves
and on slippery or wet roads, and when driv­ ing too close to objects ahead. The ESC and
its integrated systems cannot always pre­
vent collisions -there is still a risk of acci­
dents!
- Press the accelerator pedal carefully when
accelerating on even, slippery surfaces such
as ice and snow. The drive wheels can spin
even when these control systems are instal­
led and this can affect driving stability and
increase the risk of a collision.
(j) Tips
-The ABS and ASR only function correctly
when all four wheels have a similar wear
condition. Different tire sizes can lead to a
reduction in engine power.
- You may hear noises when the systems de­
scribed are working.

Brakes
New brake pads
New brake pads do not achieve their fu ll braking
effect duri ng the first 250 mi (400 km) . They
must be "broke n in" first. Howeve r, you can com­
pensate fo r th e slightly reduced braking force by
pressing f irm ly on the b rake pedal. Avo id heavy

Operating nois e
Noises may occur when br aking depend ing on the
speed, b raking force and outside cond itions such
as tempe rature and humidity.
Effect of water and road salt
I n ce rtain s ituations, for example after driving
through wa ter, in heavy ra in, afte r ove rnig ht con ­
densat ion 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 w ith a few careful brake applica­
tions.
At highe r speeds and with the windshie ld wipers
turned on, the brake pads press against the brake rotors for a short amount of time . Th is action,
which is not felt by the driver, happens at regular
intervals and ensures a better reaction time for
the brakes in wet weather .
The braking eff ect can also be reduced if you are
driving on salted roads and you do not apply the
brakes for long periods of time. The layer of salt
on the brake rotors and pads must be worn off
first when the brakes are applied .
Corrosion
Leaving the vehicle parked for long periods of
time, low mi leage and avoiding heavy braking
can contribute to corrosion on the brake rotors
and to dirty brake pads .
If you usually avoid heavy braking or if there is
corros ion present, occasional heavy braking at
h igh speeds is recommended to clean the brake
rotors and pads
¢ ,& .
Brake system malfunct ion
if you notice that the brake pedal travel has sud­
denly increased, then a brake c ircuit in the dual­
circu it brake system may have malfunct ioned.
Drive to an authorized Aud i dea ler or aut horized
Aud i Serv ice Facility immediately to have t he
p roblem co rrected . On the way there, drive with
reduced speed and keep in mi nd that you w ill
need a longer d istance to s top and you w ill need
to p ress the brake pedal har der.

Brake booster
The brake booster ampl ifies the press ure you ap­
ply to the brake pedal.
_&. WARNING
- New brake pads do no t achieve the ir full
braking effect during the first 2 50 m i
-
(400 km). They m ust be "b roken in" first .
However, you can compensate fo r the
slightly reduced braking force by pressing
firm ly on the brake pedal. Avoid heavy brak­
ing during the break-in period .
- On ly app ly the bra kes for the purpose of
cleaning the brake system when road and
traffic conditions permit. You must not en­ danger other road users . This increases the
ris k of an accident.
- On steep slopes, reduce the speed and se­

si tion. D rive as little as possible while press­
ing the bra ke pedal and avoi d pu tting your
left foot on the brake pedal while dr iv ing.
This could cause the bra kes to overhea t and
impair the efficiency of the b rakes.
- Do not let the bra kes "grind" by always
keep ing your foot on the bra ke pe dal. This
can cause the brakes to overheat, inc rease
wear and increase braking distance unneces­
sarily .
- Ce rtain weather and operating conditions
such as d riving through water, dr iv ing in
heavy rain or driv ing after wash ing your ve­
hicle can impai r the effective ness of the
brakes . In t he win ter, ice may build up o n
the bra ke pa ds, rotors and dr ums. Check
t hese components by b raking carefully. Ap ­
plyi ng the brakes carefully seve ral times
dries the brakes and removes ice build-up .
- The efficiency o f th e brakes can also be im­

-If the front spoiler is damaged or you install
another spoiler, make sure the front wheel
brakes are vent ilated properly. Otherwise,
the brake system could overheat, wh ich re­
duces the ir effectiveness .
- Failure of a brake circuit impairs b raking
performance , which increases brak ing dis­
tance. Avoid driving the vehicle and have it
towed it to the nearest author ized Audi
dealer or author ized A udi Se rvice Facility.
- Never let the vehicle roll while t he engine is
stopped because this increases the risk of a n
acc iden t.
- If the bra ke booste r is not working, you will
have to press m uch ha rder on the bra ke
ped al to compensate for the lac k of th e
booster.
- Never let the brakes "rub " by pressing the
pedal light ly when bra king is no t actually
ne cessary . T his cause s the brakes to over­
hea t and i ncre ases br aking di stance and
ca uses wear.
- B efo re driv ing downh ill a long dis tance on a
steep h ill, decrease your speed and se lec t a
l ower gear . This makes use of the engine
braking effect and relieves the brakes . If
you need to b rake additionally, brake in in­
tervals and not continuously.
@ Tips
- If the brake booste r is not working, you
must press the brake pedal with much more
fo rce than normal.
- If you retrofit yo ur vehicle with a front spoil­
er, whee l
covers or similar items, make sure
that the air flow to the front whee ls is not
i nterr upted . Otherw ise the brake system
ca n become too hot .
