CONTROLS
Cornering
If the set speed is too high for cornering, it will
be reduced slightly in the bend. However, since
bends may not be anticipated in advance,
moderate your speed when cornering.
The system has a restricted detection range.
Situations can arise on tight bends where a
vehicle driving in front will not be detected or
will be detected very late.
When your vehicle is approaching a bend, the
curvature may cause the system to respond
temporarily to vehicles in the other lane. If the
system responds by decelerating the vehicle,
you may compensate for this by accelerating
briefly. When the accelerator pedal is released
again, the system will resume control of the
vehicle's speed.
Driving off
The vehicle cannot drive off automatically in
some situations, for example:
▷ On steep upward gradients.
▷ Before bumps or rises in the road.
▷ When towing a heavy trailer.

Driver assistance systems
Online Edition for Part no. 01405A5E758 - VI/22
In such cases, press the accelerator pedal.
Weather
In adverse weather and lighting conditions,
system functionality may be limited as follows:
▷ Impaired detection of vehicles.
▷ Brief interruptions when vehicles have al-
ready been detected.
Pay attention when driving and respond to the
prevailing traffic situation. If necessary, inter-
vene actively, for example by braking, steering
or taking avoidance manoeuvre.
Drive power
The set speed is also maintained when driving
downhill. The vehicle may not achieve the set
speed on uphill gradients if there is not enough
drive power.
In ECO PRO drive mode, it is possible that the
vehicle will drive faster or slower than the set
speed setting in some situations, for example
on downhill or uphill gradients.
Speed Limit Assist
Principle
Speed Limit Assist helps the driver to observe
speed limits. A suggested speed can be adop-
ted.
General
When the systems in the vehicle, for example
Speed Limit Info, detect a change in the speed
limit, it is possible to adopt this new speed
value for the following systems:
▷ Manual Speed Limiter.
▷ Cruise Control.
▷ Active Cruise Control with distance control.
The speed value is proposed as a new set
speed for adopting. The relevant system must
be activated for the speed value to be adopted.
