Driving
-For reasons of safety, cruise control should
not be used in the city, in stop-and-go traf
fic, on twisting roads and when road condi
tions are poor (such as ice, fog, gravel, heavy rain and hydroplaning) -you could
have an 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 causes cruise control 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
control is intended for use only when the ve
hicle is being operated on paved roads, and
is not suitable for use off-road or on un
paved roads.
- 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 other
cruise control functions remain active as
long as the indicator light
tii;(O~i4 (US mod
el)/lil (Canadian model) is on .
{D) Tips
The brake lights illuminate as soon as the
brakes apply automatically.
Changing speed

tap the lever in the
010 direction ¢ page 95,
fig. 108 .
.,. To increase/decrease the speed quickly, hold
the lever in the
010 direction until the de
sired speed is displayed.
You can also press the accelerator pedal down to
increase your speed, e.g. if you want to pass
someone. The speed you saved earlier will re
sume as soon as you let off of the accelerator
pedal.
If, however, you exceed your saved speed by
S mph
(10 km/h) for longer than 5 minutes, the

Hybrid drive
Introduction
Applies to vehicles: with hybrid drive
General informatio n
The hybrid drive is a combined drive concept that
automatically switches between combustion en
gine and electric drive types or combines them.
All work on high voltage systems is intended only
for high voltage technicians and may only be per
formed by authorized service facilit ies in accord
ance w ith Aud i regulations.
T he high voltage system is composed of the fol
lowing h igh voltage components: the high volt
age battery, the power electronics, the electric
motor, the high voltage A/C compressor and the
orange high voltage wir ing.
Hi gh vo ltag e b att e ry
The high voltage battery is located in the luggage
compartment underneath the cargo floor . You do
not need to perform any maintenance work on
the high voltage battery . Additional informat ion
about the h igh voltage battery can be fo und un
der
~ page 104 .
The high voltage battery service plug is also
found underneath an orange cover under the car
go floor. The serv ice plug is provided only for use
by service personnel and must not be
removed by
others who are not trained to use it.
A WARNING
-The voltage in the high voltage system is life
threatening . Touching a damaged high volt
age component can result in a fatal electric
shock. The components in the high voltage
system are marked with a warning label which
warns against the h igh voltage .
- Never perform work on orange high voltage
cables or on high voltage components . Only
authorized repair fac ilities that are certified
may perform work on the high voltage sys
tem .
Hyb ri d
-Never open or remove the service plug cover
in the center of the cargo floor .
- Never damage, alter or
remove the orange
high voltage cable or disconnect it from the
high voltage system .
- Aud i regulations must be followed during
all work performed on the high voltage sys
tem and high voltage components.
A WARNING ,-
While in electric drive mode, the vehicle pro-
duces considerably less idling, driving and op
erating noise than when the combust ion en
g ine is running . This may make it difficu lt or
i mpossible fo r others such as pedestrians and
chi ldren to hear and notice the vehicle when it
i s in elect rical drive mode. Th is can lead to
collisions and injuries, for example in low
traffic areas, when maneuvering or when driv
ing in
reverse.
A WARNING
--Never leave the vehicle unattended while in
the drive ready mode. The vehicle could begin moving if the accelerator pedal is pressed ,
even if the combustion engine is switched off .
This may cause coll is ions and severe or fatal
i njuries. When the vehicle enters dr ive ready
mode, the status message h~

is switched off and the hybrid system is de-
activated.
(D Note
- The h igh vo ltage system can be damaged if
the vehicle underbody comes into contact
w ith the ground . Immediately drive your
ve
hicle to an authorized repair facility and
have it inspected.
- Do not transport fluids in open containers in
the luggage compartment. Spilled fluids
can seep underneath the cargo f loor. This
can damage the high voltage system.

Audi adaptive cruise control and braking guard
Audi adaptive cruise
control and braking
guard
Introduction
Applies to vehicles: with Audi adaptive cruise contro l
The adaptive cruise contro l system assists the
driver by regulating vehicle speed and helping to
maintain a set distance to the veh icle 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 vehi
cle. This helps to make driving more comfortable
on long highway stretches.
The braking guard system can warn you about an
impending collision and initiate braking maneu
vers

Adaptive cruise control and braking guard have
technical limitations 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 veh icles: with Audi adaptive cruise control
Fig. 116 Front of t he veh icle: Posit ion of radar sensor
The area that contains the radar sensor
c::> fig . 116 must never be covered by st ickers or
other objects or obstructed 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
c::> page 207. The
same appl ies for any modifications made in the
front area .
106
The function of the adaptive cruise control sys
tem and braking guard is limited under some
condit ions:
- Objects can only be detected when they are
within sensor range
<:!) page 108, fig . 119.
-The system has a limited ability to detect ob
jects that are a short distance ahead, off to the
side of your vehicle or moving into your lane.
- Some k inds of veh icles are hard to detect; for
example motorcycles, veh icles with high
ground clearance or overhanging loads may be
detected when it is too late or they may not be
detected at all.
- When driving through curves ¢
page 107.
- Stationary objects i::!) page 107.
& WARNING
-Always pay attention to traffic when adaptive
cruise control is switched on and braking
guard is active. As the driver, you are still re
sponsible for starting and for maintaining
speed and distance to other objects . Braking
guard is used to assist you . The driver must
a lways take action to avoid a collision . The
driver is always responsible fo r braking at the
correct time.
- Improper use of adaptive cruise contro l can
cause collisions, other accidents and serious
personal injury.
- Never let the comfort and convenience that
adapt ive cr uise control and braking guard
offe r dist ract you from the need to be alert
to traffic cond itions and the need to remain
in full control of your ve hicle at all times,
- Always remember that the adaptive 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 veh icle.
If registered by the radar sensor, veh icles o r
obstacles that are not moving can trigger a
coll ision warning and if confirmed by the
video camera, an acute collision warning. ..,

Audi adaptive cruise control and braking guard
Audi braking guard
Description
Applies to vehicles: with Audi adaptive cruise contro l
Fig. 126 In strument cluste r: appro ach warning
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 braking guard do?
When detected in time, the system can assess
situations when a veh icle ahead brakes suddenly
or if your own vehicle i s 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 situat ion.
The system advises you of variou s 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 will not be
able to avoid a collision. The indic ator light .
in the display comes on.
- The
approach warning is given 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 given, it may only be pos
s ib le to avo id a collision by swerving or braking
sharply. The indicator light . and indicator in
the display will warn you about the danger
¢fig. 126. You will also hear an acoustic signal.
If you do not react fast enough or do not react at
a ll to the situation, braking guard will intervene
by braking and the message
Braking guard: Acti
vated
will appear.
l) Thi s is no t a vail able in som e coun trie s.
112
- If a collision is imminent, the system will first
provid e an
acute warning by briefly and sharply
app ly ing the b rakes.
- If you do not react to the acute warning, brak
ing guard can brake within the limits of the sys
tem . This reduces the vehicle 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 collision ll.
- If the braking gua rd senses that you are not
braking hard enough when a collision is immi
nent, it can increase the braking force.
Which functions can be controlled?
You can switch braking guard and the distance/
approach warning on or off in the radio/MM
I*
¢ page 113 , Settings in the radio/MM!* .
A WARNING
Lack of attent ion can cause collisions, other
accidents and ser ious 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 respon
sible for braking at the correct time .
- Always pay close attention to traffic, even
when the braking guard is switched on. Be
ready to intervene and be ready to take
complete control whenever necessary. Al
ways keep the safe and legal distance be
tween your vehicle and vehicles up ahead .
- Braking guard works within limits and will
not respond outside the system limits, for
examp le when approach ing a stopped vehi
cle or stationary obstacle (end of a traffic
jam or vehicle that has broken down in traf
fic) .
- Always remember that the radar sensor for
the braking guard works only within defined
detection and range limits that may prevent
the proper detection of other vehicles.
- The radar sensor's function and range can
be reduced by rain, snow and heavy spray.
Moving vehicles up ahead may not be
