appears, the cruise control system has been deac-
tivated. There is a temporary malfunction, for ex-
ample the brakes are overheating. Switch the
cruise control system on again later.
Efficiency assist
Applies to: vehicles with efficiency assist
Efficiency assist can assist the driver with predic-
tive information in order to reduce fuel consump-
tion. Depending on vehicle equipment, the sys-
tem may access data from the navigation system,
the camera behind the windshield, and the radar
sensors.
Adjusting the efficiency assist
You can adjust efficiency assist functions individ-
ually. The settings depend on the vehicle equip-
ment.

Driver assistance
— When a route is planned using the naviga-
tion system*, then system displays messag-
es based on an assumed route. Without
route guidance, the system displays mes-
sages based on an assumed route.
— The wording of the message may vary de-
pending on the selected Audi drive select*
mode and the selected gear. No messages
are displayed when in the "S" driving pro-
gram.
Predictive control
Applies to: vehicles with Audi adaptive cruise control and effi-
ciency assist
With predictive control, efficiency assist adapts
the set speed in adaptive cruise control @
=> page 128 based on detected speed limits and
the upcoming route. Once the system no longer
detects any incidents ahead, adaptive cruise con-
trol will accelerate back up to the last speed that
the driver set. After switching on the ignition, the
availability of predictive control is indicated by a
message when the adaptive cruise control is first
activated.
The displays depend on the vehicle equipment.
Requirements
— Adaptive cruise control is actively regulating
=> page 129.
— The system can only react to speed limits that
are 15 mph (20 km/h)2) or higher.
Overriding control
The driver can override the predictive control to
the route ahead at any time by pressing the ac-
celerator or brake pedal. If the system changes
the vehicle speed to adapt to speed limits, you
can change the speed using the lever
=> page 129, fig. 116.
Setting predictive control
You can switch off predictive control functions or
adjust them individually. The settings depend on
the vehicle equipment.

also set With tolerance if desired. In this scenar-
io, you may fall below or exceed the set speed in
favor of increased efficiency.
Adjustment to curves along route - Regulates
based on the route ahead, for example by con-
trolling the speed at which the vehicle drives
through curves.
Messages
Ife and a message with Predictive control is
displayed when there is a malfunction, the effi-
ciency assist functions are unavailable or limited.
A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the area in front of the
sensors > page 116 and try to turn on the sys-
tems again later.
If the malfunction remains, drive to an author-
ized Audi dealer or authorized Audi Service Facili-
ty immediately to have the malfunction correct-
ed.
ZX WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Pay attention to traffic and the area around
your vehicle when predictive control is
switched on. The driver is always responsible
for assessing the traffic situation.
— The system does not consider “right of way”
rules and does not respond to traffic lights,
so lack of driver attention in these situations
can increase the risk of an accident.
— The speed when driving through curves may
be different from what you as a driver would
do or may not be suitable for the weather

Fig. 112 Example: driving into a curve
In some situations, the adaptive cruise control
function is limited and you must assume control
of the vehicle when necessary, for example by ap-
plying the brakes.
— When driving into a curve > fig. 112 and out of
acurve, the system may react to a vehicle in the
neighboring lane and apply the brakes. You can
override the system by pressing the accelerator
pedal briefly.
— The system works with the various sensors and
cameras in the vehicle. Vehicles can only be de-
tected once they are within the area and range
covered by the sensors > page 115, fig. 104.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the system may ac-
celerate unexpectedly.
— The system does not react to a stationary vehi-
cle in the same lane if it expects that you can
easily drive around the stationary vehicle by
turning the steering wheel.
128
— The system cannot react to stationary objects,
such as vehicles at the end of a traffic jam, es-
pecially when traveling at high speeds.
— The system has a limited ability to detect
vehicles that are a short distance ahead, off to
the side of your vehicle, or moving into your
lane.
— Objects that are difficult to detect, such as mo-
torcycles, vehicles with high ground clearance,
or vehicles with an overhanging load, may be
detected late or not detected at all.
— The system does not respond to people, ani-
mals, or objects that are crossing or approach-
ing from the opposite direction.

Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— The activated adaptive cruise control is only
an assist system, and the driver is still re-
sponsible for controlling the vehicle. The
driver is especially responsible for braking,
steering, starting to drive, and controlling
the speed and the distance from other
vehicles.
— Turn on the adaptive cruise control only if
the surrounding conditions permit it. Always
adapt your driving style to the current visu-
al, weather, road, and traffic conditions.
— Switch adaptive cruise control off temporari-
ly when driving in turning lanes, on express-
way exits or in construction zones. This pre-
vents the vehicle from accelerating to the
stored speed when in these situations.
— Ifyou press the [SETIQ) button when driving
at speeds below 15 mph (20 km/h)”, the
minimum possible speed that the system
can maintain will be set. If no vehicle is de-
tected ahead of you, the vehicle will acceler-
ate up to that speed.
(i) Tips
— Always keep your hands on the steering
wheel so you can be ready to steer at any
time. The driver is always responsible for
adhering to the regulations applicable in
the country where the vehicle is being oper-
ated.

— If you switch the ignition or the adaptive
cruise control system off, the set speed is
erased for safety reasons.
— When adaptive cruise control is switched
on, the ESC and ASR automatically switch
on.
— The system cannot be switched off or it may
be interrupted if the road exceeds the maxi-
mum possible grade for safe operation.
Setting the distance
Applies to: vehicles with Audi adaptive cruise control
B4M-0234
Fig. 117 Operating lever: setting the distance
If you adjust the speed, you must also change the
time gap to the vehicle driving ahead. The higher
the speed, the greater the distance that is need-
ed.
> Tap the rocker switch to display the distance
that is currently set.
> To increase or decrease the distance in incre-
ments, tap the switch again toward @) or G).
The newly-set distance will be shown briefly, for
example with the indicator light. In the Driv-
er assistance display, a graphic display is shown
instead of the indicator lights > page 128,
fig. 114. The display matches the functions of
the indicator lights.
When approaching a vehicle driving ahead, the
adaptive cruise control system brakes to match
that vehicle's speed and then adjusts to the set
distance. If the vehicle driving ahead accelerates,
then the adaptive cruise control will accelerate
up to the speed that you have set.
The following distances can be set:

The time between is approximately 1
eee second. This setting corresponds toa
= distance of approximately 92 feet (28
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.3
seconds. This setting corresponds toa
distance of approximately 118 feet (36
m) when traveling at 62 mph (100
km/h).
The time between is approximately 1.8
seconds. This setting meets the general
recommendation of “half the speed
shown on the speedometer”. This cor-
responds to a distance of approximate-
ly 164 feet (SO m) when traveling at
62 mph (100 km/h).
The time between is approximately 2.4
seconds. This setting corresponds to a
distance of approximately 219 feet
(67 m) when traveling at 62 mph (100

Traffic jam assist supports the driver when driv-
ing in traffic jams or in heavy traffic.
In a speed range under 40 mph (65 km/h), the
system can help to keep the vehicle within a lane
calculated by the system. Within the limits of the
system, the system controls the steering auto-
matically when adaptive cruise control is switch-
ed on. Since traffic jam assist is only an assist
system, the driver must always keep his or her
hands on the steering wheel and be ready to
steer. The driver can override the control at any
time by actively steering.
The system is designed for driving on express-
ways and highways.

PN eye
Applies to: vehicles with Audi pre sense basic
Audi pre sense basic is automatically active at
speeds of approximately 20 mph (30 km/h) and
higher. The system can trigger the Audi pre sense
preemptive safety measures during emergency
braking and dangerous braking maneuvers as
well as in unstable driving situations, such as
oversteering or understeering.
ZA WARNING
Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
Audi pre sense front
Applies to: vehicles with Audi pre sense front
The Audi pre sense front system uses the data
from the radar sensors and calculates the proba-
bility of a rear-end collision. Within the limits of
the system, an impending collision with the front
of the vehicle can be detected in both urban and
rural speed ranges.
Early warning/acute warning
The system can recognize various dangerous sit-
uations. The early warning occurs if:
— Avehicle driving ahead brakes suddenly
— Your own vehicle approaches a significantly
slower vehicle or stationary vehicle in the direc-
tion of travel
The message Audi pre sense [@) or Audi pre
sense wa and a warning tone will warn you about
the danger.
140
If there is an impending collision with vehicles,
there may also be an acute warning in the form
of sharp braking. You will also be warned by an
indicator in the instrument cluster display. When
this warning occurs, it may only be possible to
avoid a collision by swerving or braking strongly.
Automatic deceleration
If you do not react to the acute warning, Audi pre
sense can brake the vehicle to a full stop within
the limits of the system if the vehicle is traveling
at low speeds. This reduces the vehicle speed in
the event of a collision.
Automatic braking force increase
If Audi pre sense determines that you are not
braking strongly enough when a collision is immi-
nent, it can increase the braking force based on
the situation.
Z\ WARNING
— Follow the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 114.
— Audi pre sense front cannot overcome natu-
ral physical laws. It is a system designed to
assist and it cannot prevent a collision in ev-
ery circumstance. The driver must always in-
tervene. The driver is always responsible for
braking at the correct time. Do not let the
increased safety provided tempt you into
taking risks. This could increase your risk of
a collision.
— Audi pre sense front does not react to cer-
tain objects, such as people/cyclists, ani-
mals, crossing or oncoming vehicles, bars,
railings, or railcars.
— Audi pre sense front may be limited or un-
available when driving in curves.
— Loose objects can be thrown around the ve-
hicle interior during sudden driving or brak-
ing maneuvers, which increases the risk of
an accident. Store objects securely while
driving.

— Avoid short circuits in the electrical system.
— Never reach into the radiator fan. The fan is
temperature-controlled and can turn on
suddenly, even when the ignition is switched
off.
— Never open the hood when there is steam or
coolant escaping from the engine compart-
ment, because there is a risk that you could
be burned. Wait until no steam or coolant is
escaping.
— The cap on the coolant expansion tank must
never be opened when the coolant is hot.
The cooling system is under pressure. There
is a risk of burns
—To protect your face, hands, and arms from
hot steam or coolant, cover the cap with a

— Ifa gear is engaged while the vehicle is sta-
tionary and the engine is running, do not
press the accelerator pedal inadvertently.
Pressing the accelerator pedal will cause the
vehicle to move, and this could result in an
accident.
— If inspections or repairs must be performed
while the engine is running, moving compo-
nents (such as the ribbed belt, generator,
and radiator fan) pose an additional risk.
— Set the parking brake first and select the
“P” (Park) selector lever position.
— Always make sure that no parts of the
body, jewelry, ties, loose clothing, and
long hair can be caught in moving engine
components. Before any work, always re-
