Start-Stop function
The combustion engine is operated on ly as
needed. Generally, the combustion engine
turns off when the vehicle is stationary and
the high voltage battery powers the electrical
vehicle systems.
The purpose of automatica lly shutting the
combustion engine off in hybrid drive mode is
to save fuel. All of the important veh icle sys
tems, such as steering, brakes and the A/C
system, cont inue to remain active. In some
cases, systems may require the combustion
engine to cont inue running when the vehicle
is stationary. When dr iv ing in congested traf
fic for long per iods of time, the combustion
engine w ill cycle on when the vehicle is sta
tionary to keep the high voltage battery
charged.

Energy recovery (recuperation)
When braking, the elect ric motor will act as a
generator creating e lectric energy that is then
stored in the high voltage battery. This also
occurs when the ve hicle is coasting or driving
downhi ll. The combustion engine is automati
cally turned off in this case.
The vehicle is braked with the electric motor
by applying ear ly and even pressure to the
brakes and using short pedal movements
¢ page 98, fig. 107 @. By doing this, a large
amount of the kinetic energy is recovered and may be stored as electric energy in the high
voltage battery. During heavy braking, the
convent ional brakes are also act ivated
c::> page 98, fig. 107 @.
The energy recovery is shown in the MMI dis
play
c::> page 104 .
Automatic start of the combustion engine
Various operating conditions cause the com
bust ion engine to start automat ically :
- The high voltage battery charge leve l is low.
- The temperature of the comb ustion engine
is low.
- The temperature of the catalyt ic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is hig h.
- The vehicle acceleration is high.
- The inclin e is steep.
- High charge level for the high voltage bat-
tery when coasting. In th is case, the h igh
voltage battery cannot absorb any mo re en
ergy and so the electric motor cannot slow
down the veh icle. The combustion engine
tu rns on (engine brake). In this situation the
h igh voltage battery will show a Ma x charge.

confirmed by the video camera, an acute
collision warning.
- 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
hydroplan ing). Using the system under
these conditions could result in a colli
sion.
- Switch adaptive cruise control off tempo
rar ily when driv ing in turning lanes, on
expressway exits or in construc tion
zones. This prevents the vehicle from ac
celerating to the set speed when in these
situations.
- Th e adaptive cruise control system w ill
not brake by itse lf if you put your foot on
the accelerator pedal. Doing so can over
ride the speed and distance regulation.
- When approaching stationary objects
such as stopped traffic, adaptive cruise
control will not respond and braking
guard w ill have limited function.
- The adaptive cr uise control system and
braking guard do not react to people, an
ima ls, objects crossing the road or on
coming objects .
- The function of the radar sensor can be
affected by reflective objects such as
guard rails, the entrance to a tunnel,
heavy rain or ice.
- Never follow a vehicle so closely that you cannot stop your vehicle safely. The
adaptive cruise control cannot slow or
brake the vehicle safely when you follow
ano ther vehicle too closely . Always re
member that the automatic braking
function cannot bring the vehicle to a sudden or emergency stop under these
conditions.
- To prevent unintended operation, always
switch adaptive cruise control off when it
is not being used.
QJ Note
The sensor can be disp laced by impacts o r
damage to the bumper, whee l housing and underbody.
That could affect the adaptive
cruise control system and braking guard. Have yo ur authorized Aud i dea ler or a u

Audi adaptive cruise control and braking guard 113
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 123 Instrument cluste r: approac h warn ing
Braking guard uses a radar sensor. It also
functions within the limits of the system
when adaptive cruise control is switched off.
What can braking guard do?
When detected in time, the system can assess
situations when a vehicle ahead brakes sud
denly or if your own vehicle is traveling at a
high speed and approaching a vehicle up
ahead that is moving more slowly . Braking
gua rd does not react if it cannot detect the
situation .
The system advises you of various situations:
- The
distance warning is given if you are too
close to the vehicle ahead for a long time. If
the vehicle ahead brakes sharply, you wi ll
not be able to avoid a collision. The indicator
light
I in the display comes on .
- The
approach warning is given when a de
tected vehicle up ahead in your lane is mov
ing much more slowly than you are or if it
brakes sharply . When this warning is given,
it may only be possible to avoid a collision
by swerving or braking sharply. The indicator
light
I and indicator in the display will warn
you about the danger
c:> fig. 123. You will al
so hear an acoustic signal.
If you do not react fast enough or do not react
at all to the situation, braking guard will inter-
ll Th is is not ava ilable in som e coun tri es.
vene by braking and the message Braking
guard: Activated
will appear.
- If a coll ision is imminent , the system will
first provide an
acute warning by briefly and
sharply applying the brakes.
- If you do not react to the acute warning,
braking guard can brake within the limits of
the system. This reduces the vehicle speed
in the event of a collision.
- At speeds under 20 mph (30 km/h), the sys
tem can initiate a complete deceleration shortly before a collision
ll.
- If the braking guard senses that you are not
braking hard enough when a collision is im
minent, it can increase the braking force .
Which functions can be controlled?
You can switch braking guard and the dis
tance/approach warning on or off in the radio/
MMI* i::!> page 114, Settings in the radio/
MMI *.
A WARNING
--==
Lack of attention can cause collisions, oth-
er accidents and serious personal injuries.
The braking guard is an assist system and
cannot prevent a collision by itself. The
driver must always intervene. The driver is
always respons ible for braking at the cor
r ect time .
- Always pay close attention to traffic,
even when the braking guard is switched
on . Be ready to intervene and be ready to
take comp lete control whenever necessa
ry. Always keep the safe and legal dis
tance between your vehicle and vehicles
up ahead.
- Braking guard works within limits and
will not respond outside the system lim
its, for examp le when approaching a
stopped vehicle or stationary obstacle (end of a traffic jam or vehicle that has
broken down in traff ic).

Automatic
transmission
tiptronic
Introduction
The automatic transmission is controlled elec
tronically. The transmission upshifts or down
shifts automatically depending on which drive
program is selected. The power is transferred
by a torque converter .
When a
mode rate d riv in g s ty le is used, the
transmission selects the most econom ica l
driving mode. It w ill then change up early and
delay the downshifts to g ive better fuel econ
omy.
T he transmission switches to a sporty mode
after a k ick-down or when the driver uses a
spo rty driving sty le characterized by quick ac
celerator pedal movements, heavy accelera
tion, frequent changes in speed and traveling
at the maximum speed.
If desired, the driver can a lso select the gears
manually ( tiptronic mode ) c:> page 12 7.

8_ WARNING
-Unintended vehicle movement can cause
serious injury .
- 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 lever to P.
- Power is still transmitted to the wheels
when the engine is running at idle. To
prevent 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, re-
duce 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
braking distance or causes complete fail
ure of the brake system .
- To preven t 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 auto
matically when it becomes too hot from
the overload. An indicator lamp
[O] illu
minates and a driver message appears
<=:> page 128when the clutch is overload
ed.
- If the engine must remain running, never
have any driving position engaged when
checking under the hood. Make sure the
selector lever has securely engaged and
is locked in P with the parking brake set
r:::> page 231 . Otherwise, any increase in engine speed may set the vehicle in mo
tion, even with the parking brake ap
plied.
(D Note
- When stopping on an incline , do not try
to hold the vehicle in place by pressing
the accelerator pedal while a driving gear is selected. This can cause the transmis
sion to overheat and can damage it. Acti
vate the parking brake or press the brake pedal to prevent the vehicle from rolling .
- Allowing the vehicle to roll when the en
gine is stopped and the selector lever is
in N will damage the transmission be
cause it is not lubricated under those cir
cumstances.
@ Tips
For safety reasons, the parking brake is re
leased automatically only when the driv
er'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 these
lector lever is in D /S and you press the brake
pedal. The transmission automatically selects
a gear that is suitable for the incline. Hill de
scent control tries to maintain the speed ach
ieved at the time of braking, within physical
and technical limitations. It may still be nec
essary to adjust the speed with the brakes .
Hill descent control switches off once the de
cline levels out or you press the accelerator
pedal.
When the speed is set in the cruise control
system
r:::> page 95, hill descent control is also
activated.
A WARNING
-
Hill descent control cannot overcome
physical limitations, so it may not be able
to maintain a constant speed under all
