Driver assistance

vehicle traveling ahead, adaptive cruise control

accelerates up to the stored speed.

WARNING

– Observe the safety precautions and note the

limitations of the assist systems, sensors,

and cameras ðpage 122 to ðpage 125.

– Pay attention to traffic and the area around

your vehicle when efficiency assist is turned

on. The driver is always responsible for as-

sessing the traffic situation.

In stop-and-go traffic, the vehicle may brake to a

full stop and then may also start driving again

automatically under certain conditions

ðpage 144.

Applies to: vehicles with traffic jam assist: In traf-

fic jams or in stop-and-go traffic, the traffic jam

assist can assist in staying within the lane detect-

ed by the system ðpage 145.

Tips

– 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.

Applies to: vehicles with predictive control: Pre-

dictive control can adjust the set speed based on

traffic and road conditions ðpage 141.

WARNING

– 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.

Observe the safety precautions and note the

limitations of the assist systems, sensors, and

cameras ðpage 122 to ðpage 125.

Tips

– The wording of the message may vary de-

pending on the Audi drive select* mode and

the selector position that are selected.

The system complies with United States FCC

regulations and ISED regulations ðpage 301.

General information

Applies to: vehicles with Audi adaptive cruise control

Depending on vehicle equipment, Audi adaptive

cruise control may consist of the following func-

tions:

Within the limitations of the system, the adap-

tive speed and distance control assists while

driving in controlling the speed and keeping the

set distance to the vehicle traveling ahead. If the

system detects a vehicle traveling ahead, the

adaptive cruise control can brake and accelerate

your vehicle within the limitations of the system.

On open roads with no traffic, it functions like a

cruise control system. The stored speed is main-

tained. When approaching a vehicle traveling

ahead, the adaptive cruise control system auto-

matically brakes to match that vehicle's speed

and then maintains the set distance as much as

possible. As soon as the system does not detect a

Fig. 109 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 ðfig. 109 and out of

a curve, the system may respond to a vehicle in

the neighboring lane and apply the brakes. You

can override the system by pressing the acceler-

ator pedal briefly.

Driver assistance

– 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 ðpage 123, fig. 101.

– When driving around tight curves, a vehicle

traveling ahead that was previously detected

may no longer be detected, and the system

may accelerate unexpectedly.

Fig. 111 Instrument cluster: driver assistance display

– The system does not respond to a stationary ve-

hicle in the same lane if it expects that you can

easily drive around the stationary vehicle by

turning the steering wheel.

The driving situation and the settings are dis-

played in the instrument cluster ðfig. 110. In

the Driver assistance ðfig. 111 display, you can

find more detailed information about the sys-

tem. The displays depend on the country and

equipment.

– The system cannot respond to stationary obsta-

cles, such as vehicles at the end of a traffic jam,

especially when traveling at high speeds.

– The system has a limited ability to detect

vehicles that are traveling 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 traveling ahead, vehicles with high

ground clearance, or vehicles with an overhang-

ing load, may be detected late or not detected

at all.

mals, or objects that are crossing or approach-

ing from the opposite direction.

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.

Preselecting a speed

You can also preselect the speed when adaptive

cruise control is not active by moving the lever in

the desired direction + / - . Activate the previ-

ously selected speed by pulling the lever toward

you in the direction of the arrow.

– If you turn off the ignition or the adaptive

cruise control system, the set speed is

erased for safety reasons.

– When adaptive cruise control is turned on,

the ESC and ASR automatically turn on.

– The system cannot be turned off or it may

be interrupted if the road exceeds the maxi-

mum possible grade for safe operation.

Turning off

If you do not want to use the adaptive cruise con-

trol for a long period of time, you can turn it off.

►

Push the lever away from you into position

until it clicks into place.

Driver intervention requests

The indicator light and the set speed will turn off.

WARNING

– Observe the safety precautions and note the

limitations of the assist systems, sensors,

and cameras ðpage 122 to ðpage 125.

– 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.

apply the brakes ð

The braking effect by the adaptive cruise control

is not strong enough to maintain a sufficient dis-

tance to the vehicle traveling ahead in this situa-

tion.

– Turn off adaptive cruise control temporarily

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.

SET

The display 1 also appears if you have opened

the Driver assistance display in the trip computer

ðpage 19.

– If you press the

button 2 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.

WARNING

– Observe the safety precautions and note the

limitations of the assist systems, sensors,

and cameras ðpage 122 to ðpage 125.
