When the dynamic cruise control is
automatically paused, it can only be
reactivated when safe conditions are
restored.Themessage"Activation
not possible, conditions unsuitable"
is displayed while reactivation is not
possible.
When the conditions allow, it is
recommended that the system be
reactivatedbypressingbutton2 or 3,
whichwillmakethecurrentspeedof
your vehicle the new cruise speed
setting,ratherthanbypressingbutton4
(on/pause)whichreactivatesthesystem
usingtheoldcruisespeedsetting,
which may be very different from the
currentspeedofyourvehicle.
Thedynamiccruisecontrolusesonlyengine
brakingtoslowthevehicle.Consequentlythe
vehiclelosesspeedslowly,aswhenreleasing
theacceleratorpedal.
Thesystemispausedautomatically:
- if the vehicle in front slows down too much
or too suddenly, and the driver does not
brake,
- if a vehicle comes between your vehicle
and the vehicle in front,
- if the system does not slow the vehicle
enoughtocontinuetomaintainasafe
distance,forexamplewhendescendinga
steephill.
Limits of operation
Astheradar'sfieldofviewisquitenarrow,itis
possiblethatthesystemmaynotdetect:
Thecruisecontroldoesnottakeaccountof:
- stationary vehicles,
- vehiclesdrivingintheoppositedirection.
- vehicles of reduced width, such as
motorcycles,forexample,
- vehiclesnotrunninginthemiddleofthe
lane,
- vehiclesenteringacorner,
- vehicleschanginglaneatthelastmoment.
Theregulationrangeislimitedtoamaximum
differenceof20mph(30km/h)betweenthe
speedsettingandthespeedofthevehiclein
front.Abovethis,thesystemgoesintopauseif
asafedistanceisnotmaintained.
Severe weather conditions (very heavy
rain, accumulations of snow in front
of the radar) can interfere with the
operationofthesystem,resultingin
thedisplayofthemessage"SYSTEM
INACTIVE:Visibilityreduced".The
function remains unavailable until the
messagedisappears.
