Driving
6Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stationary (e.g.
red
lights, traffic jams). The engine automatically
restarts - START mode - as soon as the driver
indicates the intention of moving off again.
Primarily designed for urban use, the function
is intended to reduce fuel consumption and
exhaust emissions as well as the noise level
when stationary.
The function does not affect the functionalities of
the vehicle, in particular the braking.
Deactivation/Reactivation
By default, the function is activated when the
ignition is switched on.
It is configured in the ADAS touch screen
application.
or

for a few seconds, then goes off.
After the engine has restarted, STOP mode is not available until the vehicle
has reached a speed of 5 mph (8
km/h).
During parking manoeuvres, STOP mode
is not available for a few seconds after

100
Driving
coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:
–
With the selector in mode
D or M: with the
brake pedal released.
–

With the selector in mode

Malfunctions
In the event of a fault with the system, this
warning lamp flashes for a few moments
on the instrument panel, then remains on,
accompanied by the display of a message.
Have it checked by a CITROËN dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►

Switch off the ignition then start the engine
again with the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver when one or more
tyres have a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes the last values

stored during
the

reinitialisation request into account. It is
therefore essential that the tyre pressure is
correct during the operation. This operation is
the driver’s responsibility.
The tyre under-inflation detection cannot, in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.

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

Adaptive cruise control
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids and
to

Cruise control - particular
recommendations.
This system automatically maintains the vehicle
speed at a value set by the driver (speed
setting), while respecting a safety distance from
the vehicle in front (target vehicle) previously set
by the driver. The system automatically manages
the acceleration and deceleration of the vehicle.
With the Stop
& Go function, the system
manages braking until the vehicle comes to a
complete stop and the restarting of the vehicle.
The brake lamps come on if the vehicle is slowed down by the system.
The system is not operational in the event of
a brake lamp failure.


To do this, the system uses a camera fitted at the
top of the windscreen and a radar fitted in the
front bumper.
Primarily designed for driving on main
roads and motorways, this system only
works with moving vehicles driving in the
same direction as your vehicle.
If the driver activates the direction
indicator to overtake a slower vehicle,
cruise control may temporarily reduce the
distance to the target vehicle to facilitate
overtaking, without exceeding the speed
setting.
