Starting/stopping the engine
Applies to vehicles: with Start-Stop-Syste m
Fig. 102 Instrument cluste r: Eng ine switched off (stop
phase)
.. Slow the vehicle to a stop using the brake
and keep pressing the brake pedal. The en
gine w ill switch off. The
[IJ indic ator light
appears in the instrument cluster display
and - also appears in the trip com
puter .
.. When you take your foot off the brake ped
al, the engine restarts. The indicator light
turns off .
Additional information
The engine will switch off in the P, 0/5 and N
positions as well as in manual mode. In the P
position, the engine will also remain off if you
take your foot off the brake pedal. The engine
starts again when you select another selector
lever position and take your foot off the brake
pedal.
If you select the R position during a Stop phase, the eng ine will start aga in .
Shift from 0/5 to P qu ickly to prevent the en
g ine from starting unintentionally when shift
ing through R.
You can determine for yourself if the engine
will stop or not by reduc ing or increasing the
amount of force you use to press the brake
pedal. For example, if you only lightly press
on the brake pedal in stop-and and-go traffic
or when tu rning, the eng ine will not switch off
when the vehicle is stationary. As soon as you
press the brake down harder, the engine will
switch off.
(D Tips
-Press the brake pedal during a stop
phase to keep the vehicle from rolling.
- When you stop and the start-stop-sys
tem turns the engine off, the ignition re
mains on. Make sure that the ignition is
switched off before exiting the vehicle.
- The ignition will turn off if you press the
!START ENGINE STOPI * button during a
stop phase.
- The image in the display is slightly differ
ent in some models.

your speed and the distance between
your vehicle and other vehicles.
- For reasons of safety, cruise control
should not be used in the city, in stop
and-go traffic, on twisting roads and
when road conditions are poor (such as
ice, fog, gravel, heavy rain and hydro
plan ing) -you could have an accident.
- Switch the cruise control off temporarily
when dr iv ing in turning lanes, highway
exits or in construction zones.
- Please note that unconsciously "resting"
your foot on the accelerator pedal causes
cru ise contro l not to brake. This is due to
the control system being overridden by
the driver's acceleration.
- Never use the cruise control when driving
off-road or on unpaved roads. The cruise
con tro l is intended for use only when the
vehicle is being operated on paved roads,
and is not suitable for use off-road or on
unpaved roads.
- If a brake system malfunction such as
overheating occurs when the cruise con
trol system is switched on, the braking
function in the system may be switched off. The other cruise control functions re

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 comb ustion
engine w ill cycle on when the vehicle is sta
tionary to keep the high voltage battery
charged.
Gliding
I f the gas pedal is not pressed and the D posi
tion is selec ted, the combustion engine re-
Hybrid 101
mains turned off up to speeds of approxi
mately 99 mph (160 km/h). Driving conserva
tive ly like this can reduce fuel consumption.
Energy recovery (recuperation)
When braking, the electric 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 i n 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. 108 @. 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
¢ page 98, fig. 108 @.
The energy recovery is shown in the MMI dis
play ¢
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 combustion engine
is low.
- The temperature of the catalytic converter is
low .
- The power output needed for the A/C sys-
t em is high.
- The vehicle speed is high.
- 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 more 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 Max charge.

Audi adaptive cruise control and braking guard 113
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise control
Fig. 124 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. 124. 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 sys tem wi ll
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).
