pedals at the same time - risk of damage to
the gearbox!
If you open the driver's door while mode
N is engaged, an audible signal will
sound. The audible signal stops when the
driver's door is closed.
At very low speeds, opening the driver's door triggers the gearbox to switch to
mode P.
In the event of battery failure, it is
essential to place the chock(s) supplied
with the tool kit against one of the wheels to
immobilise the vehicle.
Special aspects of automatic mode
The gearbox selects the gear that provides
optimal performance based on ambient
temperature, road profile, vehicle loading and
driving style.
For maximum acceleration, press the accelerator

speed limit information from the system.

104
Driving
The units for the speed limit (mph or km/h) depend on the country you are
driving in.
This should be taken into account to ensure
you observe the speed limit.
For the system to work properly when
changing countries, the speed unit of the
instrument panel must match that of the
country you are driving in.
Automatic sign reading is a driving aid system and does not always display the
correct speed limits.
The speed limit signs present on the road
always take priority over those displayed by
the system.
The system is designed to detect signs that
conform to the Vienna Convention on road
signs.
Specific speed limits, such as those for
heavy goods vehicles, are not displayed.
The display of the speed limit on the
instrument panel is updated when passing
a speed limit sign intended for cars (light
vehicles).
Activation/Deactivation
By default, the system is automatically activated
at every engine start.
The settings are changed via the Driving/Vehicle touch screen menu.
Information displayed on
the instrument panel


1. Detected speed limit indication
or
2. End of speed limit indication


The system is active but is not detecting speed
limit information.


On detecting speed limit information, the system
displays the value.


For a suggested maximum speed, the first time
that the vehicle exceeds it
by more than 3 mph
(5
km/h) (e.g. 59 mph (95 km/h)), the speed is
displayed and flashes for 10 seconds (depending
on version).
Operating limits
The system does not take account of reduced
speed limits, especially those imposed in the
following cases:
–

Atmospheric pollution.
–

Towing.
–

Driving with a space-saver type spare wheel
or snow chains fitted.
–


T
yre repaired using the temporary puncture
repair kit.
–

Y
oung drivers.
The system may not display the speed limit if it
does not detect a speed limit sign within a preset
period and in the following situations:
–

Road signs that are obstructed, non-standard,
damaged or bent.
–


Obsolete or incorrect maps.
Speed setting
recommendations
The driver can select the speed displayed by the
Road signs recognition system as the speed
setting for the speed limiter, cruise control or
adaptive cruise control using the OK button.
In the event of rain detection, the system offers
the driver a speed setting lower than the speed
read/from the map in order to adapt to weather
conditions (e.g.on motorways, the proposed
speed is 68 mph (110 km/h) instead of 81 mph
(130 km/h).

107
Driving
6The speed limiter is temporarily deactivated and
the displayed speed setting flashes.
►
Release the accelerator pedal to return to
below the speed setting.
When exceeding the speed is not due to the
driver's action (e.g.

in case of a steep slope), an
audible signal is triggered immediately.
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 speed setting.
If necessary, apply the brakes to control your
vehicle’s speed.
When the vehicle speed returns to the speed
setting level, the speed limiter operates again:
the speed setting display becomes fixed again.
Off
► Press 1-LIMIT: the speed limiter information
display disappears.
Malfunction
In the event of a malfunction, dashes are
displayed flashing and then fixed instead of the
speed setting.
Have it checked by a CITROËN dealer or a
qualified workshop.
Cruise control - Specific
recommendations
The cruise control function does not guarantee compliance with the maximum
authorised speed and the safety distance
between vehicles, the driver remains
responsible for their driving.
In the interest of public safety, only use cruise
control if the traffic conditions enable vehicles
to drive at a steady speed and maintain an
adequate safety distance.
Remain vigilant while cruise control is
activated. If you press and hold one of the
speed setting modification buttons, your
vehicle may change speed very abruptly.
When descending a steep hill , the cruise
control system cannot prevent the vehicle
from exceeding the set speed. Brake if
necessary to control the vehicle speed.
On steep climbs or when towing, the set
speed may not be reached or maintained.
Exceeding the programmed speed
setting
You can temporarily exceed the speed
setting by pressing the accelerator pedal (the
programmed speed flashes).
To return to the speed setting, release the
accelerator pedal (when the set speed is
reached again, the displayed speed stops
flashing).
Operating limits
Never use the system in the following
situations:
–

In an urban area with the risk of
pedestrians crossing the road.
–


In heavy traffic (except versions with the
Stop & Go function).
–


On winding or steep roads.
–


On slippery or flooded roads.
–


In poor weather conditions.
–


Driving on a speed circuit.
–

or studded tyres.
Cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and the
Cruise control - particular
recommendations.
This system automatically maintains the vehicle’s speed at the value programmed
by the driver (speed setting), without the use of
the accelerator pedal.
Cruise control is switched on manually.
It requires a minimum vehicle speed of 25 mph
(40

km/h).
With a manual gearbox, third gear or higher must
be engaged.

a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualified workshop.
Active lane departure warning system
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids .
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary
lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.


Operating conditions
– Vehicle speed between 40 and 112 mph (65
and 180 km/h).
–

Road marked with a central dividing line.
–


Steering wheel held in both hands.
–


Direction indicators not activated.
–


ESC system activated and operational.
The system helps the driver only if there is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
The driver must hold the steering wheel with
both hands in a way that allows control to
be maintained in circumstances where the
system is not able to intervene (for example, if
the central dividing line disappears).
Operation
