Driving -> Speed limiter for Your Citroen C4 SUV Second Generation (2010-2018)

Driving  
The alert is given by a warning lamp which  
comes on in the door mirror on the side in  
question as soon as a vehicle - car, lorry,  
cycle - is detected.  
For this, the following conditions must be met:  
-
-
-
-
all the vehicles must be moving in the  
same direction,  
the speed of your vehicle is between 7 and  
75 mph (12 and 140 km/h),  
when you overtake a vehicle with a speed  
difference of less than 6 mph (10 km/h),  
when a vehicle overtakes you with a speed  
difference of less than 15 mph (25 km/h),  
the traffic must be flowing normally,  
in the case of an overtaking manoeuvre,  
if this is prolonged and the vehicle being  
overtaken remains in the blind spot,  
you are driving on a straight or slightly  
curved road,  
-
-
No alert will be given in the following situations:  
-
when overtaking (or being overtaken by) a  
very long vehicle (lorry, coach...) which is  
at the same time detected at the rear in the  
blind spot angle and present in the driver's  
forward field of vision,  
in very heavy traffic: vehicles detected in  
front and behind are confused with a lorry  
or a stationary object,  
-
in the presence of immobile objects  
(parked vehicles, barriers, street lamps,  
road signs...),  
-
-
your vehicle is not pulling a trailer, a  
caravan...  
-
-
with vehicles moving in the opposite  
direction,  
driving on a sinuous road or a sharp  
corner,  
-
-
when overtaking quickly.

Operating fault  
In the event of a fault, the warning lamp in the  
button flashes then goes off.  
Have it checked by a CITROËN dealer or a  
qualified workshop.  
The system may suffer temporary  
interference in certain weather  
conditions (rain, hail...).  
In particular, driving on a wet surface  
or moving from a dry area to a wet area  
can cause false alerts (for example, the  
presence of a fog of water droplets in  
the blind spot angle is interpreted as a  
vehicle).  
In bad or wintry weather, ensure that  
the sensors are not covered by mud, ice  
or snow.  
Take care not to cover the warning zone  
in the door mirrors or the detection  
zones on the front and rear bumpers  
with adhesive labels or other objects;  
they may hamper the correct operation  
of the system.

To deactivate the system, press this button  
again; the warning lamp goes off.

The state of the system remains in memory on

The system is automatically deactivated  
when towing with a towbar approved by  
CITROËN.

Speed limiter  
System which prevents the vehicle from exceeding the speed programmed by the driver.  
Steering mounted controls  
Displays in the instrument panel  
The speed limiter is switched on manually.  
The minimum programmed speed is  
20 mph (30 km/h).  
The programmed speed remains in the  
system memory when the ignition is  
switched off.  
The speed limiter is a driving aid that  
cannot, in any circumstances, replace the  
need to observe speed limits or the need  
for vigilance on the part of the driver.

Switching on  
Adjusting the limit speed  
setting  
You do not have to switch the speed limiter on  
in order to set the speed.  
To modify the limit speed setting from the  
current speed of the vehicle:  
F
in steps of +/- 1 mph (km/h), make  
successive short presses on button 2 or 3,  
continuously, in steps of +/- 5 mph (km/h),  
press and hold button 2 or 3.  
To modify the limit speed setting using  
memorised speeds and from your Audio system  
(only with the monochrome screen C):  
F
F
with the system first activated.  
For more information on memorising speeds,  
refer to the corresponding section.  
F
Turn the wheel 1 to the "LIMIT" position  
to select the speed limiter; the function is  
paused.  
F
F
make a long press on button 2 or 3, the  
system displays the memorised speed  
closest to the actual speed of the vehicle;  
this setting becomes the new limit speed.  
to choose another memorised speed, make  
another long press on button 2 or 3.

F
If the speed setting is suitable (last speed  
setting programmed in the system) press  
button 4 to switch the speed limiter on.  
To modify the limit speed setting using  
memorised speeds and from the touch screen  
tablet:  
F
press button 5 to display the six memorised  
speed settings,

setting.  
F
Pressing button 4 temporarily interrupts the  
function (pause).  
This setting becomes the new limit speed.

Driving  
Temporarily exceeding the  
programmed speed  
Operating fault  
When the limit speed is exceeded but is not  
due to action by the driver, there is an audible  
signal to complete the alert.  
Once the speed of the vehicle returns to  
the programmed setting, the speed limiter  
functions again: the display of the programmed  
speed setting becomes steady again.  
Flashing dashes indicate a fault with the speed  
limiter.  
Have it checked by a CITROËN dealer or a  
qualified workshop.  
F
If you want to temporarily exceed the  
programmed limit speed, press firmly on  
the accelerator pedal, going beyond the  
point of resistance.  
The speed limiter is deactivated temporarily  
and the displayed programmed speed flashes.  
The use of mats not approved by  
CITROËN may interfere with the  
operation of the speed limiter.  
To avoid any risk of jamming of the  
pedals:  
On a steep descent or in the event of  
sharp acceleration, the speed limiter  
will not be able to prevent the vehicle  
from exceeding the programmed speed.  
-
ensure that the mat is positioned  
correctly,  
Switching off  
F
Turn wheel 1 to the "0" position: the  
display of information on the speed limiter  
disappears.  
-
do not fit one mat on top of another.
