CITROEN C4 Spacetourer Handbook page 159

When the cruise control is working, take
care if keeping pressed one of the cruise
control programmed speed change
buttons: this can lead to a very rapid
change in the speed of your vehicle.
Do not use adaptive cruise control on
slippery surfaces or in heavy traffic.
When descending a steep hill, the cruise
control system cannot prevent the vehicle
from exceeding the programmed speed.
On steep climbs or when towing, the
programmed speed may not be reached
or maintained.
The use of mats not approved by
CITROËN may interfere with the operation
of the cruise control.
To avoid any risk of jamming of the pedals:
- ensure that mats are secured correctly,
- never fit one mat on top of another.
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.).
The message "SYSTEM INACTIVE:
Reduced visibility". is displayed to indicate
that the function is in standby.
Clean the front bumper regularly.
If the front bumper is to be repainted or
retouched, contact a CITROËN dealer
or a qualified workshop. Certain types of
paint could interfere with the operation of
the radar.
Adaptive cruise control
until vehicle is stopped/
until 19 mph (30 km/h)
Function until vehicle is stopped: with
automatic gearbox
Function until 19 mph (30 km/h): with manual
gearbox
This system provides the following
functions:
- Automatically maintains the
vehicle at the speed set by the
driver.
- Automatic adjustment of the
distance between your vehicle
and the one in front.
With an automatic gearbox, automatic
adjustment of the distance can cause your
vehicle to come to a complete stop.
Cruise control remains active after
changing gear regardless of the gearbox
type.
It manages the acceleration and deceleration
of the vehicle by automatically acting on the
engine and the braking system.
For this purpose there is a radar installed in the
front bumper.
