2020 CITROEN RELAY sensor

Driving
The message "Vehicle close" is displayed.Level 2 (red): visual and audible alert,
signalling that a collision is imminent.
The message "Brake! " is displayed.
Level 3: finally, in some cases, a haptic alert
in the form of micro-braking can be given,
confirming the risk of collision.
Where the speed of your vehicle is too
high approaching another vehicle, the
first level of alert may not be displayed: the
level 2 alert may be displayed directly.
Important: the level 1 alert is never displayed
for a stationary obstacle or when the " Close"
trigger threshold has been selected.
Intelligent emergency
braking assistance
If the driver brakes, but not sufficiently to avoid a
collision, this system will supplement the braking,
within the limits of the laws of physics.
This assistance will only be provided if the driver
presses the brake pedal.
Active Safety Brake

This function, also called automatic emergency
braking, intervenes following the alerts if the
driver does not react quickly enough and does
not operate the vehicle's brakes.
It aims to reduce the speed of impact or avoid a
collision where the driver fails to react.
Operation
The system operates under the following
conditions:
– The vehicle's speed does not exceed 50 mph
(80 km/h) when a stationary vehicle is detected.
– The vehicle's speed is between 3 mph and
53 mph (5 km/h and 85 km/h) when a moving
vehicle is detected.
This warning lamp flashes (for about 10 seconds) once the function is acting
on the vehicle's brakes.
With a manual gearbox, in the event of automatic
emergency braking until the vehicle comes to a
complete stop, the engine may stall.
The driver can maintain control of the vehicle at any time by sharply turning the
steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop, the
automatic braking is maintained for 1 to 2
seconds.
Malfunction
In the event of a system malfunction, this
warning lamp comes on on the instrument
panel, accompanied by an onscreen message
and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
If these warning lamps come on
after the engine has been switched
off and then restarted, contact a CITROËN
dealer or a qualified workshop to have the
system checked.
Audible rear parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever.

6Audible rear parking sensors
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to your vehicle, the system consists of 4
proximity sensors installed in the rear bumper.
They detect any obstacle, e.g. person, vehicle,
tree, barrier, which is behind the vehicle while
manoeuvring.
Certain types of obstacle detected at the
beginning of the manoeuvre will no longer be
detected at the end of manoeuvre if they are
located in the blind spots between and under the
sensors. Examples: stake, roadworks cone or
pavement post.
The rear parking sensors may be associated
with the reversing camera.
Switching on
► Engage reverse gear with the gear lever.

The proximity information is indicated by an
audible signal which becomes more rapid as the
vehicle approaches the obstacle.
When the distance between the rear of
the vehicle and the obstacle is less than
approximately 30 centimetres, the audible signal
becomes continuous.
Switching off
► Disengage reverse gear and shift to neutral.
Malfunction
If this warning lamp lights up on the
instrument panel, accompanied by a
message in the display, contact a CITROËN
dealer or a qualified workshop.
Reversing camera
Refer to the General recommendations on the
use of driving and manoeuvring aids .


If fitted to the vehicle, the camera is located at
the rear by the third brake lamp.


It transmits views to the screen installed in the
cab.
It can be activated or deactivated via the settings
menu of the touch screen audio and telematics
system.

88
Driving
This rear vision system is a driving aid. The
reversing camera may be associated with the
rear parking sensors.
Switching on
The camera comes into operation when reverse
gear is engaged and remains active up to
approximately 9 mph (15 km/h). It is deactivated
above 11 mph (18 km/h).
The camera also comes on with the vehicle
stationary, when the rear doors are opened.
Switching off
When engaging forward gear, the last image
remains displayed for approximately 5 seconds,
then goes out.
The last image also remains displayed in the
same way, with the vehicle stationary, when
closing the rear doors.
With optimum vehicle conditions (position
on the road, loading level) the maximum
area of visibility covered by the camera has a
field depth approximately 3 m long and 5.5 m
wide.
The area of visibility may vary depending on
the external weather conditions (brightness,
rain, snow, fog, etc.), the load in the vehicle
and the position of the vehicle on the road.
When cleaning the camera and the screen,
avoid using a detergent or a tool which may
scratch the glass.
Use a non-abrasive cloth or a small brush.

Practical information
Before each use
Check that the towball is correctly locked,
verifying the follow points:
– the green mark on the wheel is in line with
the green mark on the towball,
– the wheel is in contact with the towball,
– the key lock is closed and the key removed;
the wheel can no longer be operated,
– the towball must not be able to move in its
carrier; test by shaking it with your hand.
During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the maximum authorised
weight for the vehicle (the Gross Vehicle
Weight - GVW), the trailer, or the sum of the
two (the Gross Train Weight - GTW).
Following use
When travelling without a trailer or load on a
towbar-mounted carrier, the towball must be
removed and the protective plug inserted in the
carrier. This measure applies particularly where
the towball might obscure visibility of the number
plate or its lighting.
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
Towing a trailer

The type-approved towable weights are entered
in your vehicle's registration certificate, as well
as on the manufacturer's plate.
For more information on the Technical
characteristics of the vehicle and
particularly on weights and towable loads,
refer to the corresponding section.
You will then have information on your vehicle's
ability to tow a trailer, a caravan, a boat, etc.
These values are also given in the sales
brochures.
We recommend using genuine CITROËN
towbars and their harnesses that have
been tested and approved from the design
stage of your vehicle, and having a CITROËN
dealer fit the towbar.
These genuine towbars are compatible with
the operation of the rear parking sensors and
the reversing camera, if your vehicle is so
equipped.
If the towbar is not fitted by a CITROËN
dealer, it must still be fitted in accordance with
the vehicle manufacturer's instructions.
