Speed assist systems

Information on the speed limiter

Speed assist systems

The speed limiter helps you to avoid exceeding a

speed that you have set. The speed can be set to

approx. 20 km/h and above. The system limits

the speed even if the accelerator is pressed. If the

accelerator is not pressed, the system will not ac-

celerate the vehicle.

Speed regulation

systems

Introduction

The speed regulation systems consist of the

cruise control system, the speed limiter and the

predictive speed limiter.

Information on the predictive speed limiter

Information on use

WARNING

– Please note the safety precautions and sys-

tem limits of the supporting systems, sen-

sors and cameras ðpage 130 to

Important: Adaptation to speed limits when

speed limiter active must be switched on in the

Driver assist menu ðpage 134. The map materi-

al on the navigation system must be updated

regularly to ensure the system can function with-

out limitations ðpage 211.

ðpage 132.

– The speed regulation systems are designed

to assist the driver. However, the driver still

maintains full responsibility for the opera-

tion of the vehicle; this applies in particular

to braking, regulating the speed and main-

taining an appropriate distance to other

vehicles.

Depending on the vehicle’s equipment, the pre-

dictive speed limiter expands the speed limiter

function by taking into account speed limits iden-

tified by the system on the route being driven.

The set speed is adjusted to the speed limit iden-

tified by the system. The system uses the traffic

sign recognition function and the data from the

navigation system as reference. The system lim-

its the speed even if the accelerator is pressed.

– When you take a turn-off, drive along a mo-

torway exit lane or pass through roadwork

sections, please temporarily switch off the

speed regulation systems. This is to ensure

that the vehicle does not accelerate to the

set speed in such situations.

Further information

It is always the driver's responsibility to keep

within the speed limit.

CAUTION

Before driving down a long, steep gradient, it

is advisable to reduce speed and select a low-

er gear. In this way you will make use of the

engine braking effect and relieve the load on

the brakes.

Whenever you switch on the vehicle and subse-

quently drive onto a motorway with no speed

limit, the system initially limits the speed to

1)

130 km/h . If you select a new set speed man-

ually while driving on a road section with no

speed limit, the setting is stored and subse-

quently applied on the next road section with no

speed limit.

Information on the cruise control system

The cruise control system helps you to remain at

a constant speed that you have set. The speed

can be set to approx. 20 km/h and above. The

system regulates to the set speed by braking and

accelerating.

When entering and exiting motorways, the sys-

tem briefly switches to the manual speed limiter.

While route guidance is active on the navigation

system, the control uses the navigation route as

a reference. Implausibilities in the control

System limitations

The system only responds to traffic signs specify-

ing a speed limit. The actual traffic signs on your

route always take precedence over the informa-

tion on the display. In certain circumstances, the

maximum permissible speed may be exceeded

while the predictive speed limiter is limiting the

current road speed.

The set speed has been exceeded;

the driver is temporarily overriding

the limit.





The cruising speed has been excee-

ded; the driver is temporarily over-

riding the limit.

If incorrect values are supplied by the camera-

based traffic sign recognition or if the map mate-

rial on the navigation system is out of date, this

can cause failures or implausibilities in the con-

trol response.

Information is also provided in the head-up dis-

play.

WARNING

Please note the safety precautions and system

limits of the supporting systems, sensors and

cameras ðpage 130 to ðpage 132.

The speed limit displayed in the instrument clus-

ter is given in the units applicable in a particular

country. For example, if 50 is displayed on the in-

strument cluster, this may signify km/h or mph,

depending on the country.

Adaptive cruise control

Introduction

The adaptive cruise control assists you while

driving by controlling the vehicle’s speed within

certain limits imposed by the system. If a vehicle

is detected in front, the adaptive cruise control

can brake and accelerate the vehicle and main-

tain the set distance to the vehicle in front as

consistently as possible within certain limits im-

posed by the system.

– Only accelerate quickly or use the kick-down

feature when the visibility and weather con-

ditions are suitable, and when the road and

traffic conditions allow you do so safely.

– Applies to vehicles with cruise control sys-

tem: Make sure you do not unintentionally

rest your foot on the accelerator, as this

could override the regulating function. The

system might not apply the brakes and

therefore not regulate the vehicle’s speed.

In congested traffic and traffic jams, the system

can brake down to a standstill and move off again

automatically under certain conditions.

you can easily steer to avoid the stationary vehi-

cle.

– The system cannot react to stationary obsta-

cles, such as the end of a traffic jam, particular-

ly at high speeds.

On vehicles with adaptive cruise assist which are

fitted with certain equipment, the lane guidance

function can provide assistance ðpage 144.

– The ability of the system to detect vehicles in

front is limited when they are too close, travel-

ling out of line, or moving into your lane.

– Objects that are not clearly discernible, e.g. a

motorcycle or cyclist travelling in front of you

and vehicles with high ground clearance or a

protruding load, are often identified late or are

not detected at all.

WARNING

Please note the safety precautions and system

limits of the supporting systems, sensors and

cameras ðpage 130 to ðpage 132.

– The system does not react to pedestrians, ani-

mals or crossing or oncoming traffic.

– The system is switched off/cannot be switched

on when the maximum possible road gradient

for safe operation has been exceeded.

– The regulating function of the adaptive cruise

control is only available when the ESC and trac-

tion control system have been switched on and

are fully functional. Switch the systems on be-

forehand if necessary.

WARNING

Fig. 95 Example: Driving into a bend

Please note the safety precautions and system

limits of the supporting systems, sensors and

cameras ðpage 130 to ðpage 132.

In some driving situations, the adaptive cruise

control functions are restricted and you may need

to intervene by, for example, braking the vehicle

yourself:

Overview of displays for the adaptive cruise

control

– When driving into a bend ðFig. 95 and driving

out of a bend, the system may react to a vehicle

travelling in the next lane and therefore brake

the vehicle. You can override this by accelerat-

ing briefly.

– The system operates on the basis of informa-

tion gathered from various sensors and cam-

eras. Vehicles cannot be detected until they are

within range and inside the sensors’ field of vi-

sion.

– In tight bends, a vehicle driving ahead which

has already been detected by the adaptive

cruise control may no longer be recognised, and

the system may accelerate unexpectedly as a

result.

You can override the predictive control at any

time by pressing the accelerator. In addition, the

control lever ðpage 152, Fig. 98 can be used to

adapt the speed limit control response.

Event symbols

The predictive control is interrupted if you make

a significant change to the speed limit control re-

sponse. The adaptive cruise assist then regulates

the speed to match the manually set value.

Depending on the vehicle’s equipment, event

symbols may indicate what the predictive cruise

control is reacting to:

– When the recuperation function is active, the

actual road speed may occasionally exceed or

fall below the set speed.

– The speed at which the system drives the ve-

hicle through a corner may not correspond

to your own driving style or ambient condi-

tions. To avoid a risk of accident, apply the

brakes manually as necessary, and reduce

the speed setting in Adaptation to route

ahead.

– The system’s control response depends on the

driving characteristics set for the adaptive

cruise assist and/or (on vehicles with Audi drive

select) the selected mode.

– After the vehicle is switched on, a speed of

130 km/h is set automatically when the vehi-

Adjusting the predictive cruise control

cle is first driven onto a motorway or similar

road, provided that no speed limits are detec-

ted and you have not set a different cruising

speed.

You can switch the predictive cruise control

on/off or adjust the individual settings in the

Driver assist menu  ðpage 134.

– If a speed above 130 km/h has been set by

 Adaptation to speed limits

the driver on motorways or similar roads, the

vehicle will accelerate back up to this set speed

after regulation for a specific event has been

completed.

The adaptation according to speed limits can be

switched on or off. The optional control setting

Adjust with tolerance can also be applied. In this

case, the actual speed can be above or below the

preset speed briefly for increased efficiency. This

may result in a delay in observing the speed limit.

– The system will only regulate the speed at mo-

torway junctions or on slip roads if these are

part of the route set in the route guidance.

– If incorrect values are supplied by the camera-

based traffic sign recognition or if the map ma-

terial on the navigation system is incorrect or

out of date, this can cause failures or implausi-

bilities in the control response.

Adaptation to route ahead

The adaptation according to the route ahead can

be switched on or off. This setting affects the

handling characteristics of the predictive control

and you can also set how fast the vehicle will

drive through corners.

– While route guidance is active on the naviga-

tion system, the control uses the navigation

route as a reference. Implausibilities in the con-

trol response can occur when route guidance is

inactive or if you leave the route.

Adaptation to right of way

The regulation for right of way that takes e.g. de-

tected stop signs into account, can be switched

on/off.
