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

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.

limits of the supporting systems, sensors and

The predictive speed limiter function is tempora-

rily unavailable. This is the case, for example, if

the speed limit is below the minimum speed

which can be set or if the function is not available

in the country where you are currently driving.

The speed will be limited to the speed which you

have set manually.

in the brake system (e.g. if the brakes over-

heat) while they are activated.

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.
