Conditions
- Cautious driving and reserved ac-
celeration .
- Release the accelerator pedal early
and entirely .
- Brake early and evenly with shor t
pedal movements.
- Reserved acce leration and early
and even braking with short pedal
movements.
- Use the
!<=!VI button sparingly.
- Intentionally take your foot off of
the gas pedal to allow for lengthy
coast ing .
- Reduce the veh icle speed by
re-
leasing the acce lerato r pedal and
not by braking.
- Avoid vehicle speeds above approx-
imately 99 mph (160 km/h).
- Use the S selec tor lever position
and tiptronic mode sparingly .
- Do not run the combustion erngine
while the veh icle is parked to warm
the engine.
- Use the rear window/exterior mir-
ror defroster and the seat heat ing
sparingly .
- Park the vehicle in a garage over-
night. Hybrid
Vehicle behavior
The kinetic energy of the vehicle
is used to
move the vehicle .
When you release the accelerator pedal en-
tirely, the combustion eng ine turns off auto-
matically and is disengaged. The veh icle
g lid es without being propelled.
The electric motor brakes the vehicle. By do- ing this, a large amount of the kinetic energy
is recovered and may be stored in the high
voltage battery in the form of electric energy .
The kinetic energy of the vehicle is used to
move the vehicle .
T he battery drains quickly when the
!<=!VI but-
ton is turned on, which can increase fuel con-
sumpt ion because electric driv ing is given
priority, even if driving with the combustion
engine on wo uld be more efficient.
When you release the accelerator pedal en-
tirely, the combustion engine turns off auto- matically and is disengaged . The vehicle
g lid es without being propelled.
Fu el consumption can be reduced by coast-
ing .
It is possible to coast up to a vehicle speed of
approximately 99 mph (160 km/h).
A sporty dr iving style increases fuel con-
sumpt ion .
The temperature of the combustion engine
rises very slowly and the fue l consumption
increases considerably.
This conserves the energy in the high voltage
bat tery so that it is available to run the veh i-
cle in electr ic mode .
This reduces exposure of the high voltage
battery to cold temperatures. The required
temperature range for the high voltage bat-
tery will then be reached more quickly after
you start driving.

Audi adapt ive cru ise control and brak ing gu ard
- For safety reasons, do not use adaptive
cruise control when driving on roads with
many curves, when the road surface is in
poor condition and/or in bad weather (such
as ice, fog, gravel, heavy rain and hydrop lan­
ing). Using the system under these condi­
t ions could resu lt in a col lision.
- Switch adaptive cruise control off tempora­
rily when driving in turn ing lanes, on ex­
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situat ions.
- The adapt ive cr uise control sys tem wi ll not
brake by itself if yo u put you r foot on the ac­
celerator pedal. Doing so can ove rride the
speed and distance regulation.
- When approach ing stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking g uard will have
limited function.
- The adapt ive cr uise control system and brak­
ing guard do not react to people, animals,
objects cross ing the road or oncoming ob­
jects .
- The function of the radar sensor can be af ­
fected by reflective objects such as guard rails, the entrance to a tunnel , heavy rain or
ice.
- Never follow a veh icle so closely that you
cannot stop your vehicle safe ly . The adap­
t ive cru ise control cannot s low or brake the
vehicle safely when you fo llow another veh i­
cl e too close ly. Always remembe r that the
automa tic brak ing funct ion c annot bring the
vehicle to a sud den or emergency stop un­
der these conditions.
- To prevent unin tended operation, always
switch adaptive c ruise control off when it is
not be ing used .
(D Note
The sensor can be displaced by impa cts or
damage to the bumper, wheel housing and
underbody . That could affect the adaptive
cruise contro l system and braking gua rd . Have
your authorized A udi dealer or authorized
Audi Service Facility check their function .

Fig. 117 Example: dri ving in to a c urve
When dr iving into a curve c:::> fig. 117 and out of a
curve, the adaptive cruise control may react to a
vehicle in the next lane and apply the brakes . You
can override or prevent the braking by pressing
the accelerator peda l briefly .
Stationary objects

The adaptive cruise contro l system only reacts to
ob jects that are moving or that the system has
already detected as moving. For example, if ave­
hicle @, which has already been de tec ted by the
adap tive cruise con trol, turns or changes lanes
and another stationary veh icle @ is located in
front of that ve hicle, the system will not react to
the stat ionary vehicle.

Audi adapt ive crui se cont rol and bra king gu ard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise co ntrol
F ig. 126 Instrument cluste r: app roac h warn ing
Braking guard uses a radar sensor. It also func­
tions within the limits of the system when adap­ tive cruise control is switched off .
What can bra king gu ard do ?
When detected in time, the system can assess
situations when a vehicle ahead brakes suddenly
or if your own veh icle is traveling at a high speed
and approaching a vehicle up ahead that is mov ­
ing more slowly . Braking guard does not react if it
cannot detect the s ituation.
The system advises you of various situations:
- The
di sta nce wa rning is given if you are too
close to the vehicle ahead for a long time.
If the
vehicle ahead brakes sharply, you will not be
able to avoid a collision. The indicator light .
in the d isplay comes o n.
- The
app roach warning is g iven when a detected
vehicle up ahead in your lane is moving much
more slowly than you are or if it brakes sharply .
When this warning is g iven, it may only be pos­
s ible to avoid a co llision by swerving or braki ng
sharp ly. The indicator light . and indicator in
t h e d isplay w ill warn yo u about the danger
¢ fig. 126. You wi ll also hear an acoust ic signa l.
If you do not react fast enough or do not react at
all to the situation, braking guard will intervene by bra king and the message
Br aking guard : A cti-
~ vat ed will appear. co ~ co
rl I.O
"' N "' 11
This is not ava ilable in som e count ries. rl
- If a collision is imminent, the system wi ll first
provide an
a cute war ning by brief ly and sharply
app ly ing the brakes.
- If you do not react to the acute warning, brak­
ing guard can brake within the limits of the sys­
tem. This reduces the veh icle speed in the event
of a collision.
- At speeds under 20 mph (30 km/h), the system
can initiate a comp lete deceleration shortly be­
fore a collisionl).
- If the braking guard senses that you are not
braking hard enough when a collision is immi­
nent, it can increase the braking force.
Which function s can b e cont roll ed ?
You can switch braking guard and the distance/
approach warning on or off in the radio/MMI*
¢ page 114, Settings in the radio/MM!*.
A WARNING
-
Lack of attention can cause collisions, other
accidents and serious personal injuries. The b raking guard is an ass ist system and cannot
p revent a coll is ion by itself. The dr iver must
a lways intervene. The driver is always respon­
s ib le for b ra ki ng at the corre ct time.
- Always pay close attent ion to traffic, even
when the b rak ing guard is switched on. Be
ready to intervene and be ready to take com ­
p lete control whenever necessary . Always
keep the safe a nd legal distance between
your vehicle and vehicles up ahead.
- Braking guard works within limits and will not respond outside the system limits, for
examp le when approaching a stopped vehi­
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf­ f ic).
- Always remember that the radar sensor for
the braking guard works on ly w ithin defined
detection and range limits that may prevent
the prope r detection of other vehicles.
- The radar sensor's funct ion and range can
be reduced by ra in, snow and heavy spray.
Moving vehicles up ahead may not be

Automatic transmission
-Never leave your vehicle with the engine
running while in gear. If you must leave your
vehicle when the engine is running, activate
the parking brake and move the selector lev­ er to P.
- Power is still transmitted 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 engine
is running and the selector lever is in D/S or
R or "tiptronic" mode is selected.
- Do not press the accelerator pedal when
changing the selector lever position while
the vehicle is stationary and the engine is
running.
- Never shift into R or P while driving.
- Before driving down a steep slope, reduce
your speed and shift into a lower gear with
"tiptronic".
- Do not ride the brakes or press the brake
pedal too often or too long when driving
down a hill. 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.
- To prevent the vehicle from rolling back
when stopping on inclines, always hold it in
place with the brake pedal or parking brake.
- Never hold the vehicle on an incline with a
slipping clutch. The clutch opens automati­
cally when it becomes too hot from the
overload. An indicator lamp[!] illuminates
and a driver message appears
<=> page 127
when the clutch is overloaded .
-If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure these­
lector lever has securely engaged and is
locked in P with the parking brake set
<=>page 221. Otherwise, any increase in en­
gine speed may set the vehicle in motion,
even with the parking brake applied.
0 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-
126
lected. This can cause the transmission to
overheat and can damage it. Activate 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 N will
damage the transmission because it is not
lubricated under those circumstances.
{!) 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 declines.
Hill descent control is activated when the selec­
tor lever is in D/S and you press the brake pedal.
The transmission automatically selects a gear
that is suitable for the incline. Hill descent con­
trol tries to maintain the speed achieved at the
time of braking, within physical and technical limitations.
It may still be necessary to adjust the
speed with the brakes.
Hill descent control switches off once the decline
levels out or you press the accelerator pedal.
When the speed is set in the cruise control sys­
tem <=>
page 95, hill descent control is also acti­
vated .
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.

Electronic Stabilization
Control (ESC)
Description
The Electronic Stabilization Control (ESC) reinfor­
ces driver safety. It reduces the risk of slipping
and improves driving stability. ESC detects criti­
cal s ituations such as the vehicle oversteering
and understeering or the wheels sp inning. The
veh icle is stab ilized by applying the brakes or re­
ducing engine torque. Once the ESC is act ive, the
indicator light
m blinks in the instrument clus­
ter.
The fol low ing systems a re integrated in the ESC:
Anti-lock brake system (ABS)
ABS prevents the wheels from locking up when
brak ing . The vehicle can still be steered even dur­
ing 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 help­
ing you to brake the vehicle.
Brake assist system
The brake assist system can decrease braking d is­
tance . It increases braking power when the dr iver
presses the brake pedal quick ly in emergency s it­
uations. You must press and hold the brake pedal
unti l the situation is over. In vehicles w ith adap ­
tive cruise control*, the brake assist system is
more sensitive if the distance detected to the ve­
hicle ahead is too small.
Anti-slip regulation (ASR)
ASR reduces engine power when the drive whee ls
begin to spin and adapts the force to the road
conditions. This makes it easier to start, acceler­
ate and drive up hills.
Smart Technology
Electronic differential lock (EDL)
The EDL brakes whee ls that are spinning and
trans fers the drive power to the other whee ls.
This function is not avai lable at higher speeds .
In extreme cases, EDL automatically sw itches off
to help keep the brake on the braked wheel from
overheating. EDL will switch on again automati­
ca lly when conditions have returned to normal.
Steering recommendation
The ESC helps to stabilize the vehicle by changing
the steering torque.
On vehicles with dynam ic steering*, ESC helps
stab ilize the steer ing in crit ical situat ions .
Selective wheel torque control
Selective wheel torque control is used when driv­
ing on curves. The front wheel on the inside of
the curve or both wheels on the inside of the
curve are braked select ively as needed. This al­
lows more precise driving in curves. The applica­
ble system may not activate when driving in wet
o r snowy conditions .
A WARNING
-
-The ESC and its integrated systems cannot
overcome the laws of physics. This is espe­
cially important on slippery or wet roads. If
the systems begin acting to stabilize your
vehicle, 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 serious
personal injuries.
- Always adapt your speed to road, traffic and
weather conditions. The risk of los ing 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 a lways prevent
coll isions - there is st ill a risk of acc idents!
- Always accelerate with special care on even,
smooth surfaces such as those that are wet
or covered with ice and snow. The drive

A WARNING
-
-Always adapt your speed to the weather,
road and traffic conditions. Do not let the in ­
creased safety provided tempt you into tak­ ing risks.
- The hill descent assist system cannot over­
come the laws of physics . Your driving style
must always be adapted to the current road
and traffic conditions.
- The hill descent assist may not be ab le to
hold your vehicle at a constant speed under
all conditions w hile driving on an incl ine (for
example if ground under the vehicle is loose) .
Braking
What affects broking efficiency?
New brake p ad s
During the first 250 miles (400 km), new brake
pads do not possess their full braking effect, they
have to be "broken in" first¢ &. .,,.
193

Smart Technolog y
Operating c ondit ion s and drivin g hab it s
The brakes on today 's automobi les are st ill sub­
ject to wear, depending largely on operating con­ ditions and driving habits¢.&. . On vehicles that
are either driven mostly in stop-and-go city traf­
f ic or are driven hard, the brake pads should be
checked by your authori zed Audi dealer more of­
ten than specified in the
Wa rra nty & Mainte­
n an ce boo kle t .
Fa ilure to have your brake pads
inspected can result in reduced brake perform­
ance.
On steep slopes, you should use the brak ing ef­
fect of the eng ine . Th is way, you prevent unnec ­
essary wear on the brake system. If you must use
your brakes, do not ho ld the brakes down contin­
uously. Pump the brakes at inte rva ls.
Operat ing no ise
Noises may occur when braking depending on the
speed, brak ing force and outside conditions such
as temperature and humid ity .
Effect of w ate r an d r oad sal t
In certain situations, for example after driving
through water, in heavy rain, after overn ight con­
densat ion or after washing your car, the braking
effect can be reduced by mo isture or ice on the
brake rotors and brake pads . The brakes must be
d ried first with a few carefu l brake applications.
At h igher speeds and with the w indshield wipers
turned on, the brake pads press against the brake rotors for a short amount of t ime . This occurs at
regular intervals without the d river noticing and
p rov ides for better brake response t ime unde r
wet conditions .
The effectiveness of the brakes can be reduced
when the vehicle is dr iven on a salt-covered road
a nd the brakes are not used . L ikew ise, you clean
off accumulated sa lt coating from brake discs
and pads with a few cautious applications of the brake ¢.&. .
Corros ion
There may be a tendency for dirt to bui ld up on
the brake pads and corros ion to fo rm on the discs
if the car is not driven regularly or on ly for short
trips with litt le use of the brakes.
194
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 d iscs by braking firmly a
few times from a moderate ly high speed¢.&. .
Fault s in the brak e system
If you shou ld notice a sudden increase in bra ke
pedal travel, then one of the two brake circuits
may have failed
¢ .&. .
Lo w b rake fluid l evel
Malfunctions can occur in the brake system if the
brake flu id leve l is too low. The brake fl uid level is
monitored electronica lly.
Brake boos ter
The brake booster increases the pressure that you
generate w ith the brake pedal. It on ly operates
whi le the engine is runn ing o r with the ig nit ion
switched on (hybrid drive*)
¢ ,& .
Brake lining we ar status
Brake lining wear may be checked by visual in ­
spection of the condition of the brake pads
through the open ings in the wheel. If necessary ,
the wheel may be removed for this inspec tion
¢ page 260, Replacing wheels .
& WARNING -
- New brake pads don't have the best stop­
ping power and m ust be "broken-in" during
the initial 250 miles (400 km) . You can com­
pensate for this by pressing the brake pedal
more f irm ly. 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 r isk -you may
cause an accident!
- Before descend ing a steep grade, reduce
speed and sh ift transmission into a lower
gea r or lower dr iving range. Do not ride the
bra kes or ho ld the peda l down too long or
too often . This could cause the bra kes to get
hot and diminish braking efficiency.
