PEUGEOT 3008 2017 Handbook page 190

Driving
The cruise control operates by day and
night, in fog or moderate rainfall.
However, it is strongly recommended
that you always keep a safe distance
from vehicles ahead, according to the
driving conditions, the weather and the
road surface.
Use the cruise control only where
the driving conditions allow running
at a constant speed and keeping an
adequate safety distance.
Do not activate the cruise control in an
urban area where pedestrians are likely
to cross the road, in heavy traffic, on
winding or steep roads, on slippery or
flooded roads, when there is snowfall,
if the front bumper or the windscreen
is damaged, or when the brake lamps
have failed.
In certain circumstances, it may not
be possible for the speed setting to be
maintained or even attained: loaded
vehicle, ascending a steep hill, etc.

The system is not intended for the
following situations:
- if the front end of the vehicle has
been modified (addition of long-range
headlamps, painting of the front
bumper),
- driving on a racing circuit,
- running on a rolling road,
- use of snow chains, non-slip covers or
studded tyres.
The use of mats not approved by
PEUGEOT may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the pedals:
- ensure that the mat is secured
correctly,
- do not fit one mat on top of another.
The camera may be disrupted or not
work in the following situations:
- poor visibility (inadequate street
lighting, falling snow, heavy rain,
dense fog, etc.),
- dazzle (headlamps of an oncoming
vehicle, low sun, reflections on
a damp road, leaving a tunnel,
alternating shade and light, etc.),
- camera or radar obstructed (mud,
frost, snow, condensation, etc.).
In these situations, detection
performance may be reduced.
Operation of the radar, located in the
front bumper, may be impaired by the
accumulation of dirt (dust, mud, etc.)
or in certain weather conditions (snow,
frost, etc.).
Clean the front bumper regularly.
Clean the windscreen regularly,
particularly the area in front of the
detection camera.
Do not allow snow to accumulate on
the bonnet or roof of the vehicle, as this
could obscure the camera.
