Cruise control system 
Applies to: vehicles with cruise control system 
The cruise control system assists the driver in 
maintaining a constant speed above approxi- 
mately 15 mph (20 km/h). The system maintains 
the desired speed by braking and accelerating. 
  
ZA WARNING 
— Always pay attention to the traffic around 
your vehicle when the cruise control system 
is in operation. As the driver, you are always 
responsible for controlling your vehicle 
speed and the distance between your vehicle 
and 
other vehicles. 
— For safety reasons, cruise control should not 
be used in the city, in stop-and-go traffic, on 
winding roads, and when road conditions are 
poor (such as ice, fog, gravel, heavy rain, 
and conditions that could lead to hydroplan- 
ing), because this increases the risk  of an ac- 
cident. 
— Switch the cruise control off temporarily 
when driving in turning lanes, highway exits, 
or in construction zones. 
—To reduce the risk of an accident, you should 
only resume the stored speed if  it  is suitable 
for the current traffic conditions. 
  
    
C) Note 
Before driving downhill a long distance ona 
steep hill, decrease your speed and use  the 
braking effect of recuperation > page 90. This 
reduces the load on the brakes. 
@) Tips 
The brake lights turn on when the brakes are 
applied automatically.

Gk / 3) Speed control system: currently un- 
available. See owner's manual 
If the indicator light turns on and this message 
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. If you remove your foot from the accelera- 
tor pedal, the efficiency assist can trigger recu- 
peration based on the situation. 
Depending on vehicle equipment, the system 
may access data from the navigation system, the 
camera behind the windshield, and the radar sen- 
sors. 
Adjusting the efficiency assist 
You can adjust efficiency assist functions individ- 
ually. The settings depend on the vehicle equip- 
ment. 
— Recuperation > page 90. 
— Predictive messages inform the driver if they 
should remove their foot from the accelerator 
pedal in order to drive more efficiently 
=> page 136. 
— Predictive control uses adaptive cruise assist in 
order to react automatically to situations ahead 
=> page 137.

Situation symbols 
Depending on vehicle equipment, the following 
symbols may be shown. The symbols indicate the 
situation to which the efficiency assist is respond- 
ing. 
Some symbols only appear if Predictive messag- 
es are switched on, and some symbols only ap- 
pear if Predictive control is switched on and 
adaptive cruise assist* is active.

ZA\ WARNING 
— Follow the safety precautions and note the 
limits of the assist systems, sensors, and 
cameras > page 123. 
—Incertain situations, the recuperation may 
brake proactively. However, the recuperation 
braking effect is limited. Always be ready to 
brake to reduce the risk  of an accident. 
      
136 
G) Tips 
— The functions depend on the navigation da- 
ta* being up-to-date and correct identifica- 
tion by the traffic sign recognition*. 
— The system only detects traffic signs  that 
specify a speed limit. 
— Except for the road network, which is re- 
corded in the navigation system’s map infor- 
mation, certain functions may not be availa- 
ble. 
— The  display in the instrument cluster is 
based on the units of measurement used for 
speed in the country where the vehicle is be- 
ing operated. As a result, a display of 50 in 
the instrument cluster can mean either 
km/h or mph, depending on the country. 
— Specific settings are stored automatically in 
the active personal profile. 
Predictive messages 
Applies to: vehicles with efficiency assist 
Requirements 
— The cruise control system* or the adaptive 
cruise assist* controls must not be active. 
— The vehicle speed must be at least 20 mph 
(30 km/h). 
— The remaining distance until the situation is 
reached must be large enough to allow the sys- 
tem to react to the situation. 
Display 
The symbol SS appears in the instrument cluster 
display if efficiency assist recommends removing 
your foot from the accelerator pedal. 
Additional symbols that indicate the situation to 
which the efficiency assist is reacting are shown 
in the Driver assistance display > page 136, Sit- 
uation symbols. 
Settings 
You can switch functions off or adjust them indi- 
vidually. The settings depend on the vehicle 
equipment. 
Applies to: MMI: Select on the home screen:  VE- 
HICLE > Charging & Efficiency > Efficiency assist 
> Predictive messages.  

Driver assistance 
  
Set speed limit - Adjusts to speed limits. You can 
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 - Can be 
switched Off or be set individually from Slow to 
Fast. The setting influences vehicle handling with 
predictive control, for example the speed for 
driving through curves. 
Messages 
as and a message with Adaptive cruise assist: 
Predictive control is displayed when there is a 
malfunction, the efficiency 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 124, fig. 97 and try to turn on 
the systems 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. 
  
  
along route setting to reduce the risk  of an 
accident. 
  
  
ZA\ WARNING 
— Follow the safety precautions and note the 
limits of the assist systems, sensors, and 
cameras > page 123. 
— 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 
and road conditions. If necessary, apply the 
brakes and reduce the selected speed to be 
     
maintained in the Adjustment to curves 
  
  
YD In certain countries 
138 
@) Tips 
— Predictive control can exceed or drop below 
the maximum permitted speed. The driver 
is responsible for adhering to the permitted 
speed limit. 
— The traffic signs on the road always take pri- 
ority over the display. The driver is always 
responsible for adhering to the regulations 
applicable in the country where the vehicle 
is being operated. 
— Ifa speed limit is detected, the marking @ 
of the set speed limit will be adjusted even 
if the adaptive cruise assist is not actively 
regulating. 
— You may temporarily fall below or exceed 
the set speed due to recuperation. 
— Control by the system depends on which 
adaptive cruise assist driving program is set 
or on the selected Audi drive select* mode. 
— After switching on the ignition and first 
driving onto a freeway or similar road with- 
out a speed limit, the system will regulate 
the speed to 80 mph (130 km/h), Then 
the system adjusts to the last speed set by 
the driver. 
— There is no adaptation to speed limits when 
driving through highway interchanges and 
when driving on or off the expressway. 
— The system can fail to provide control or the 
control may be faulty if the values from the 
camera-based traffic sign recognition* are 
incorrect or the navigation system map data 
is outdated. 
— When route guidance is switched on, the 
system adapts to the route provided by the 
navigation system. Driving without route 
guidance or leaving a route can result in 
faulty control. 
— Specific settings are stored automatically in 
the active personal profile. 
   

Driver assistance 
  
system expects that  you can easily drive around 
the stationary vehicle by turning the steering 
wheel. 
— The adaptive cruise assist may not react to sta- 
tionary obstacles, such as the end of a traffic 
jam, especially at high speeds. 
— The adaptive cruise assist 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 adaptive cruise assist does not respond to 
people, animals, or objects that are crossing or 
approaching from the opposite direction.

ZA\ WARNING 
— Follow the safety precautions and note the 
limits of the assist systems, sensors, and 
cameras > page 123. 
— The activated adaptive cruise assist 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 vehi- 
cles. 
— Activate the adaptive cruise  assist only if the 
surrounding conditions permit it. Always 
adapt your driving style to the current visu- 
al, weather, road, and traffic conditions. 
— Switch the adaptive cruise assist off tempo- 
rarily when driving in turning lanes or high- 
way exits. This prevents the vehicle from ac- 
celerating to the stored speed when in these 
situations. 
— If you press the [SET|) button when driving 
at speeds below 20 mph (30 km/h), then 20 
mph (30 km/h) will be set because that is 
the minimum speed that can be set. If no 
vehicle is detected ahead of you, the vehicle 
will accelerate up to that speed. 
  
      
G) Tips 
— Always keep  your hands on the steering 
wheel. 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 assist off, the stored speed is erased 
for safety reasons. 
142 
— When the adaptive cruise assist is switched 
on, the ESC and the ASR are switched on  au- 
tomatically. 
— The system cannot be switched off if the 
road exceeds the maximum possible grade 
for safe operation.

Within the limits of the system, lane guidance 
provides corrective steering to assist the driver 
with keeping the vehicle in the center of the lane 
as much as possible. This feature can be deacti- 
vated. 
Switching lane guidance on and off 
Requirement: lane guidance must be selected in 
the adaptive cruise assist settings > page 146. 
> Press the button -arrow- > fig. 112. 
If lane guidance is selected and switched on, ad- 
ditional lane guidance assists the driver by pro- 
viding corrective steering when the adaptive 
cruise assist distance control is active. 
Overview of displays and lane guidance 
limitations 
In the Driver assistance display, the Bae indi- 
cator light informs you if lane guidance is availa- 
ble @ > page 140, fig. 109. 
If the Hi or indicator light turns on white on 
at least one side, or the indicator light turns 
on white in the Driver assistance display, then >

lane guidance is not active. This may be due to 
the following reasons: 
— The necessary lane marker lines have not been 
detected (for example, in a construction zone 
or because the lines are obstructed by snow, 
dirt, water, or lighting) 
— The lane is too narrow or too wide 
— The curve is too narrow 
— Visibility is obstructed by a rise or dip. 
— The driver's hands are not on the steering 
wheel 
  
ZA WARNING 
Follow the safety precautions and note the 
limits of the assist systems, sensors, and 
cameras > page 123. 
      
@ Tips 
— Always keep  your hands on the steering 
wheel. The driver is always responsible for 
adhering to the regulations applicable in 
the country where the vehicle is being oper- 
ated. 
— It is recommended to only switch on lane 
guidance on well-constructed roads. 
— Specific settings are stored automatically in 
the active personal profile. 
— The button -arrow- switches lane guidance 
availability and the lane departure warning 
on or off simultaneously, if lane guidance is 
selected in the adaptive cruise assist set- 
tings. 
Setting the distance 
Applies to: vehicles with adaptive cruise assist 
  
B4M-0234 
  
      
Fig. 113 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 (4) or @). 
The newly set distance is shown briefly, for exam- 
ple with the indicator light. In the Driver as- 
sistance display, a graphic display is shown in- 
stead of the indicator lights > page 140, 
fig. 109. The display matches the functions of 
the indicator lights. 
  
When approaching a vehicle driving ahead, the 
adaptive cruise assist brakes to the set speed and 
then maintains the set distance. If the vehicle 
driving ahead accelerates, then the adaptive 
cruise assist will also accelerate up to the speed 
that you have set. 
The following distances can be set: 
  
Meaning 
    
The time between is approximately 1 
second. This setting corresponds to a 
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).
