Hybrid
Start-Stop function
The combustion engine is operated on ly as need
ed . Generally, the combustion engine turns off
when the vehicle is stationary and the high volt
age battery powers the electrical vehicle sys
tems.
The purpose o f automatica lly shutting the com
bustion engine off in hybrid drive mode is to save
fuel. All of the important vehicle systems, such
as steering, brakes and the A/C system, continue
to remain active. In some cases , systems may re
qu ire the combustion eng ine to continue running
when the vehicle is stationary . When dr iv ing in
congested traff ic for long per iods of t ime, the
combustion eng ine will cycle on when the veh icle
is stationary to keep the high voltage battery
charged.
Gliding
If the gas pedal is not pressed and the D posit ion
is selected, the combustion engine remains
turned off up to speeds of approximately 99 mph
(160 km/h) . Driving conservative ly like th is can
reduce fuel con5umption .
Energy recovery (recuperation)
When braking, the electric motor will act as a
generator creating e lectr ic energy that is then
sto red in the high voltage battery. This also oc
curs when the vehicle is coasting or driving down
hi ll. The combustion engine is automat ica lly
turned off in this case .

Driving situa- Conditions
tions
- Shift into the D position .
Starting from a -
Release the brake pedal. The vehicle is braked with
the electric motor by
applying early and even pressure to the brakes
and using short pedal movements
¢ page 101,
fig. 116 @. By doing this, a large amount of the
kinet ic energy is recovered and may be stored as
electric energy in the high voltage battery. Dur
i ng heavy brak ing , the conventional brakes are al
so act ivated
¢ page 101, fig . 116 @.
The energy recovery is shown in the MMI display
¢page 107 .
Automatic start of the combustion engine
Various operating conditions cause the combus
tion eng ine to start automatically:
- Th e high voltage battery charge level is low.
- Th e temperature of the combustion engine is
low .
- Th e temperature of the catalytic converter is
low .
- T he power output needed for the A/C system is
high.
- The vehicle speed is high .
- The vehicle acceleration is high .
- The incline is steep .
- High charge level for the high voltage battery
when coasting. In this case, the high voltage battery cannot absorb any more energy and so
the electric motor cannot slow down the veh i
cle. The combust ion engine turns o n (engine
brake) . In this situation the high voltage bat
t ery w ill show a Max charge.

Vehicle behav ior
The kinetic energy of the vehicle is used to
move the vehicle .
When you release the accelerator pedal en-
tirely, the combustion engine turns off auto-
mat ica lly and is disengaged. The vehicle
g lides 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 h igh
voltage battery in the form of electric energy .
The kinetic energy of the vehicle is used to
move the vehicle .
The battery dra ins 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 driv ing with the combustion
engine on wo uld be more efficient.
When you release the accelerator pedal en-
tirely, the combustion engine turns off auto- mat ically and is disengaged . The vehicle
g lides without being propelled .
F ue l consumption can be reduced by coast-
i ng.
It is possible to coast up to a vehicle speed of
approximately 99 mph (160 km/h).
A sporty driving style increases fue l con-
sumption .
The temperature of the combustion engine
rises very s lowly and the fuel consumption in-
creases considerably.
This conserves the energy in the high voltage
battery so that it is available to run the vehi-
cle in electr ic mode .
This reduces exposure of the high voltage
battery to cold temperat ures . The required
temperature range for the high voltage bat-
tery will then be reached more quickly after
you sta rt driving .

Audi adaptive cruise
control and braking
guard
Introduction
App lies to: veh icles with Audi adaptive cruise contro l
The adaptive cruise control system assists the
driver by regulat ing vehicle speed and helping to
maintain a set distance to the vehicle ahead,
within the limits of the system.
If the system de
tects a moving vehicle up ahead, adaptive cruise
control can brake and then accelerate your veh i
cle . This helps to make driving more comfortable
on long highway stretches .
The braking gua rd system can warn you about an
impend ing collision and initiat e braking maneu
vers
¢ page 115.
Adaptive cruise control and braking guard have
technical lim itations that you must know, so
please read th is section carefully, understand
how the system works and use them properly at
all times.
General information
General information
Applies to: vehicles with Audi adaptive cruise control
Fig. 122 Fro nt o f th e ve hicle: Pos it ion of rada r sen sor
The area that contains the radar sensor
¢
fig . 122 must never be covered by st ickers or
other objects or obs tructed with dirt, insects,
snow or ice that w ill interfere w ith the adaptive
cruise control system and braking guard. For in
formation on cleaning, refer to¢
page 204 . The
same applies for any modifications made in the
front area . T
he function of the adaptive cruise control sys
tem and braking guard is limited under some
condit ions:
- Ob jects can on ly be de tected when they are
within sensor range
q page 111, fig . 125.
-The sys tem has a limited ability to de tect ob
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane .
- Some kinds of veh icles are hard to detect; for
examp le motorcycles, ve hicles w ith hig h
ground clearance or overhanging loads may be
detected when it is too late or they may not b e
detected at all.
- When driving through curves
¢ page 110 .
- Stationa ry objects q page 110 .
,&_ WARNING
-= -Always pay attention to t raffic when adaptive
cruise control is switched on and braking
g uard is active. As the driver, you are still re
sponsible for starting and for maintain ing
speed and distance to other objects . Braking
g uard is used to ass ist you . The driver must
a lways take act ion to avoid a co llision . The
driver is always respons ible for braking at the
cor rect time.
- I mproper use of adaptive cruise control can
cause collisions, other accidents and ser ious
pe rsonal injury.
- Never let the comfort and conven ience that
adapt ive cr uise control and braking g uard
offe r distract you from the need to be a lert
to traffic cond itions and the need to remain
in full control of your vehicle at all times,
- Always remember that the adapt ive cruise
control and braking guard have limits -they
will not slow the vehicle down or maintain
the set distance when you dr ive towards an
obstacle or something on or near the road
that is not moving, such as vehicles stopped
in a traff ic jam, a stalled or disab led vehicle .
If reg istered by the radar sensor, vehicles or
obstacles that a re not mov ing can trigger a
coll is ion warning and if confi rmed by the
video camera, an acute co llision wa rning.

Audi adaptive cruise control and braking guard
-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 ra in and hydroplan
ing). Using the system under these condi·
tions could result in a collision.
- Switch adaptive cruise control off tempora
rily when driving in turning lanes, on ex
pressway exits or in construction zones. This
prevents the vehicle from accelerating to
the set speed when in these situations .
- The adaptive cruis e control system will not
brake by itself if you put your foot on the ac
celerator pedal. Doing so can override the
speed and distance regu lation.
- When approaching stationary objects such
as stopped traffic, adaptive cruise control
will not respond and braking guard will have
limited function.
- The adaptive cruise control system and
braking guard do not react to people, ani
mals, objects crossing the road or oncom ing
objects.
- 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 vehicle so closely that you
cannot stop your vehicle safely. The adap·
t ive cruise control cannot slow or brake the
vehicle safely when you fo llow another veh i
cle too closely. Always remember that the
automatic braking function cannot bring the
vehicle to a sudden or emergency stop un
der these conditions .
- To prevent unintended operation, always
switch adaptive cruise control off when it is
not being used.
(D Note
The sensor can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. That could affect the adaptive
cruise control system and braking guard .
Have your authorized Audi dealer or author
ized Audi Service Facility check their function.

In curves
App lies to : vehicles wit h Audi adapt ive cruise control
Fig. 123 Example: driv ing into a curve
When driving into a curve c:::> fig . 123 and out of a
curve, the adapt ive 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 pedal briefly.
Stationary objects
Applies to: vehicles wi th Audi adaptive cruise control
Fig . 124 Examp le: object chang ing lanes and stat ionary
ob ject
The adaptive cruise control system only reacts to
objects that are moving or that the system has
already detected as moving . Fo r example, if ave
hicle @, which has already been detected by the
adaptive cruise control, turns or changes lanes
and another stationary vehicle @ is located in
front of that vehicle, the system will not react to
the sta tionary veh icle.
