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.
Switching the system on
Applies to: vehicles with cruise control system
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.
BFV-0220
() Note
— Conventional drive system:Before driving
downhill a long distance on a steep hill, de-
crease your speed and select a lower gear.
This makes use of the engine braking effect
and reduces the load placed on the brakes.
— Plug-in hybrid drive: Before driving downhill
a long distance on a steep hill, decrease
your speed and use the recuperation braking
effect > page 114. This reduces the load on
the brakes.
@ Tips
The brake lights turn on when the brakes are
applied automatically.

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.

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.
Description
Slow down
(predictive messages only)
Speed limit
(example)
Speed limit removed
Exit ahead
Intersection ahead
Traffic circle ahead
(predictive control only) If the indica-
tor light turns on in green and red, it
is indicating that there is a difference
between the speed limit and the set
speed.
ZA WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
—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.
@ 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.
— 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 mph
or km/h, depending on the country.
— Except for the road network, which is re-
corded in the navigation system’s map infor-
mation, certain functions may not be availa-
ble.
Predictive messages
Applies to: vehicles with efficiency assist
The symbol BS 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 165.
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.
Switching Predictive messages on or off
Applies to: MMI: Select on the home screen: VE-
HICLE > Charging & Efficiency > Efficiency assist
> Predictive messages.
ZA\ WARNING
— Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
— Pay attention to traffic and the area around
your vehicle when efficiency assist is switch-
ed on. The driver is always responsible for
assessing the traffic situation.
G) Tips
— The traffic signs on the road always take pri-
ority over the display. The driver is always
responsible for adhering to the regulations
165
Page 168 of 362
Driver assistance
applicable in the country where the vehicle
is being operated.
— 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.
Adaptive cruise assist
General information
Applies to: vehicles with adaptive cruise assist
Depending on the vehicle equipment, the adap-
tive cruise assist may consist of the following
functions:
Within the limits of the system, the adaptive
speed assist assists the driver in controlling the
speed and the set distance to the vehicle driving
ahead. If the system detects a vehicle driving
ahead, the adaptive speed assist can brake and
accelerate your vehicle within the limits of the
system. On open roads with no traffic, it Func-
tions like a cruise control system. The stored
speed is maintained. When approaching a vehicle
driving ahead, the adaptive speed assist auto-
matically brakes to match that vehicle's speed
and then maintains the set distance as much as
possible. Once the system does not detect a vehi-
cle driving ahead, adaptive speed assist will ac-
celerate up to the set speed.
The additional lane guidance assists the driver
with corrective steering in order to stay in the
lane. You can adjust if the adaptive cruise assist
will provide support with lane guidance
=> page 169, Switching lane guidance on and off.
In stop-and-go traffic and in traffic jams, the ve-
hicle may brake to a full stop and then may also
start driving again automatically under certain
conditions.
Applies to: vehicles with efficiency assist: Predic-
tive control can adjust the speed based on traffic
166
and road conditions > page 170, Predictive con-
trol.
ZA WARNING
Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras > page 150.
@ Tips
The system complies with United States FCC
regulations and ISED regulations > page 341.
mitations
Applies to: vehicles with adaptive cruise assist
B4m-0093
Fig. 117 Example: driving into a curve
In some situations, the adaptive cruise assist
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. 117 and out of
a curve, 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 151, fig. 108.
— When driving around tight curves, a vehicle
driving ahead that was previously detected may
no longer be detected, and the adaptive cruise
assist may accelerate 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.
