lected distance in certain situations, including if

you are driving significantly faster than vehicles

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 making an evasive maneuver, if needed.

System limits of the sensors

Additional information:

▷

Cameras, refer to page 37.

Radar sensors, refer to page 38.

Detection range

The detection capability of the system and the

For instance, two-wheeled vehicles may not be

detected.

210

Driver assistance systems

CONTROLS

Cornering

Weather

The following restrictions can occur under un-

favorable weather or light conditions:

▷

Poorer vehicle detection.

Short-term interruptions for vehicles that

are already recognized.

Drive attentively, and react to the current sur-

rounding traffic situation. If necessary, inter-

vene actively, for instance by braking, steering

or making an evasive maneuver.

When the set speed is too high for a curve,

the speed is reduced slightly. Because curves

may not be anticipated in advance, drive into a

curve at an appropriate speed.

Drive power

The set speed is also maintained downhill. The

speed may not be maintained on uphill grades

if the drive power is insufficient.

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.

In ECO PRO driving mode, the vehicle may

exceed or drop below the set desired speed

in some situations, for instance on downhill or

uphill grades.

Speed Limit Assistant

Principle

Speed Limit Assistant supports driving at the

speed limit. A suggested speed can be ap-

plied.

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 decel-

erates you may compensate for it by briefly

accelerating. After releasing the accelerator

pedal the system is reactivated and controls

speed independently.

General information

When the systems in the vehicle, e.g., Speed

Limit Info, detect a change of the speed limit,

this new speed value can be applied for the

following systems:

▷

Manual Speed Limiter.

Cruise control.

Driving off

In some situations, the vehicle cannot drive off

automatically; for example:

Active Cruise Control with Distance Control.

The speed value is suggested as the new de-

sired speed to be applied. To apply the speed

value, the corresponding system must be acti-

vated.

▷

On steep uphill grades.

In front of bumps in the road.

In these cases, step on the accelerator pedal.
