Safety information

Vehicle features and options

WARNING

This chapter describes all standard, country-

specific and optional features offered with the

series. It also describes features that are not

necessarily available in your vehicle, e. g., due

to the selected options or country versions.

This also applies to safety-related functions

and systems. When using these functions and

systems, the applicable laws and regulations

must be observed.

The system does not relieve from per‐

sonal responsibility to assess the traffic situa‐

tion. Based on the limits of the system, it can‐

not independently react to all traffic situations.

There is a risk of an accident. Adjust driving

style to traffic conditions. Watch traffic closely

and actively intervene where appropriate.◀

WARNING

An unsecured vehicle can begin to move

and possibly roll away. There is a risk of an ac‐

cident. Before exiting, secure the vehicle

against rolling.

Active Cruise Control with

Stop & Go function ACC

In order to ensure that the vehicle is secured

against rolling away, observe the following:

Concept

Using this system, a desired speed and a dis‐

tance to a vehicle ahead can be adjusted using

the buttons on the steering wheel.

▷

Set the parking brake.

On uphill grades or on a downhill slope,

turn the front wheels in the direction of the

curb.

The system maintains the desired speed on

clear roads. For this purpose, the vehicle ac‐

celerates or brakes automatically.

▷

On uphill grades or on a downhill slope,

also secure the vehicle, e.g., with a wheel

chock.◀

If a vehicle is driving ahead of you, the system

adjusts the speed of your vehicle so that the

set distance to the vehicle ahead is main‐

tained. The speed is adjusted as far as the

given situation allows.

WARNING

The desired speed can be incorrectly ad‐

justed or called up by mistake. There is a risk

of an accident. Adjust the desired speed to the

traffic conditions. Watch traffic closely and ac‐

tively intervene where appropriate.◀

The distance can be adjusted in several steps.

For safety reasons, it depends on the respec‐

tive speed.

If the vehicle ahead of you brakes to a halt, and

then proceeds to drive again within a brief pe‐

riod, the system is able to detect this within the

given system limits.

WARNING

Risk of accident due to too high speed

differences to other vehicles, for instance in

the following situations:

General information

Each time the rocker switch is pressed to

the point of resistance, the desired speed

increases or decreases by approx.

1 mph/1 km/h.

Make sure that the difference between current

speed and stored speed is not too large before

calling up the stored speed. Otherwise, unin‐

tentional braking or accelerating may occur.

Each time the rocker switch is pressed

past the resistance point, the desired

speed changes by a maximum of 5 mph/

10 km/h.

In the following cases, the stored speed value

is deleted and cannot be called up again:

Deceleration

Cornering

The system also does not decelerate in the fol‐

lowing situations:

▷

For pedestrians or similarly slow-moving

road users.

▷

For red traffic lights.

For cross traffic.

For oncoming traffic.

Swerving vehicles

If the desired speed is too high for a curve, the

speed is reduced slightly, although curves can‐

not be anticipated in advance. Therefore, drive

into a curve at an appropriate speed.

The system has a limited detection range. Sit‐

uations can arise in tight curves where a vehi‐

cle driving ahead will not be detected or will be

detected very late.

A vehicle driving in front of you is not detected

until it is completely within the same lane as

your vehicle.

If a vehicle driving ahead of you suddenly

swerves into your lane, the system may not be

able to automatically restore the selected dis‐

tance. It may not be possible to restore the se‐

lected distance in certain situations, including

if you are driving significantly faster than vehi‐

cles driving ahead of you, for instance when

rapidly approaching a truck. When a vehicle

driving ahead of you is reliably detected, the

system requests that the driver intervene by

braking and carrying out evasive maneuvers, if

needed.

When you approach a curve the system may

briefly report vehicles in the next lane due to

the bend of the curve. If the system deceler‐

ates you may compensate it by briefly acceler‐

ating.

After releasing the accelerator pedal the sys‐

tem is reactivated and controls speed inde‐

pendently.

Driving away

In some situations, the vehicle cannot drive off

automatically; for example:

▷

On steep inclines.

From bumps in the road.

In these cases, step on the accelerator pedal.

The concept

Using this system, a desired speed can be ad‐

justed using the buttons on the steering wheel.

The system maintains the desired speed. The

system accelerates and brakes automatically

as needed.

▷

Safety information

Drive attentively, and react to the current traffic

situation. If necessary, intervene actively, for

instance by braking, steering or evading.

WARNING

The system does not relieve from per‐

sonal responsibility to assess the traffic situa‐

tion. Based on the limits of the system, it can‐

not independently react to all traffic situations.

There is a risk of an accident. Adjust driving

style to traffic conditions. Watch traffic closely

and actively intervene where appropriate.◀

Engine power

The desired speed is also maintained downhill,

but may not be maintained on uphill grades if

engine power is insufficient.

Malfunction

WARNING

The system cannot be activated if the radar

sensor is not aligned correctly. This may be

caused by damage incurred, for instance dur‐

ing parking.

The use of the system can lead to an in‐

creased risk of accidents in the following situa‐

tions, for instance:

▷

On winding roads.

In heavy traffic.

A Check Control message is displayed if the

system fails.

On slippery roads, in fog, snow, or wet

conditions, or on a loose road surface.

The function for detecting and responding

when approaching stationary vehicles may be

limited in the following situations:

There is a risk of accidents or risk of damage to

property. Only use the system if driving at con‐

stant speed is possible.◀

▷

During calibration of the camera immedi‐

ately after vehicle delivery.

WARNING

▷

If the camera is malfunctioning or dirty. A

Check Control message is displayed.

The desired speed can be incorrectly ad‐

justed or called up by mistake. There is a risk

of an accident. Adjust the desired speed to the

traffic conditions. Watch traffic closely and ac‐

tively intervene where appropriate.◀
