Stop & Start (auto Stop & Go) function
Operation
Going into engine STOP mode
The "AS &G" warning lamp comes on in
the instrument panel or the instrument
panel screen and the engine goes into
standby after a few seconds:
-

w

ith a manual gearbox , with the vehicle
stationary and your foot on the brake, when
you put the gear lever into neutral and
release the clutch pedal.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the START/STOP
button. When the engine is stopped
automatically, the operation of certain
vehicle systems, such as for example,
braking, power steering... are modified.

Special cases: STOP mode not
available
STOP mode is not invoked when:
-
t he driver's seat belt is not fastened,
-

t
he driver's door is open,
-

t
he bonnet is open,
-

t
he minimum time period of 30 seconds
since starting the engine has not elapsed,
-

t
he vehicle has not exceeded 3 mph
(5
km/h) since the last engine start,
-

t
he vehicle has restarted less than
10
seconds ago,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
-

t
he "AS &G" warning lamp is
flashing in the instrument panel.
This operation is perfectly normal.
The Stop & Start (Auto Stop & Go) function puts the engine temporarily into standby during stops in the traffic (red lights, traffic jams, or other...).
The

engine restarts automatically as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start (Auto Stop & Go) function reduces fuel consumption and exhaust emissions as well as the noise level when
stationary.
If you move the gear lever, the "AS &G"
warning lamp flashes, accompanied by
an audible signal.
The alert stops as soon as the gear
lever is returned to the neutral position.

Going into engine START mode
The "AS &G" warning lamp goes off
and the engine starts automatically:
-

w

ith a manual gearbox , when you fully
depress the clutch pedal. For safety reasons or to ensure smooth
operation, START mode is invoked
automatically when:
Special cases: START invoked

ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
If the system has been deactivated in
STOP mode, the engine will not start.
At any time, press the "AS &G O FF "


switch to
deactivate the system.
Deactivation
In this case the "AS &G" warning lamp
flashes for few seconds, then goes off.
This operation is perfectly normal.This is confirmed by the "AS &G O FF "
warning lamp coming on in the instrument
panel or instrument panel screen.
If the bonnet is opened while the engine
is in standby, the "AS &G" warning lamp
flashes, accompanied by an audible
signal. The engine will not restart
automatically.
To restart the engine with the bonnet
open, use the ignition key or press the
START/STOP button, while pressing
fully on the brake and clutch pedals.

Four wheel drive system
System which permits the selection of a transmission mode in relation to the driving conditions.
Three transmission modes are available and can be selected manually by the driver in accordance with his requirements.
You can change transmission mode when
stationary or while driving.
The transmission mode can be selected by
turning the control A.
Selecting the transmission
mode
4WD AUTO (position 1)
The vehicle operates with four wheel drive and
provides optimum traction for all levels of grip.
This is the vehicle's normal and regular
operating mode, the distribution of the torque
between the front and rear axles is controlled
automatically.
The distribution favours the front wheels,
the transfer of torque to the rear wheels is
managed electronically by the control unit
in relation to the level of grip, so providing
optimum road holding.
4WD LOCK (position 2)
The vehicle operates with four wheel drive in
this mode also.
It is recommended when grip is particularly
poor or difficult (sand, mud, slopes, ...).
2WD (position 3)
The vehicle operates with front two wheel drive.
This is suitable for use on a tarmac roads or
where the driver considers that there is no risk
of loss of grip (dry road).
Display in the instrument panel
The transmission mode is displayed in the
form of an intermittent display in the instrument
panel screen when the transmission mode is
selected.The selection of this mode is
recommended when the level of grip
permits.
Driving

119
As the engine torque is applied to all
four wheels, the condition of the tyres
has a considerable impact on the
per formance of the vehicle.
Ensure that all four tyres are in good
condition.
Avoid driving the vehicle in sandy or
muddy areas or in other areas in which
the wheels could spin.
Spinning the wheels places the
transmission components under
pressure and could cause a serious
malfunction.
Do not drive the vehicle through deep
water.
Avoid driving over excessively uneven
terrain (risk of scraping under the body
or of grounding on crossing a bridge).
Operating faults
If the selected transmission mode display
flashes, the vehicle switches automatically to
front "2WD" transmission mode.
It is then no longer possible to select the
transmission mode using the control A .
If the message "SLOW DOWN" is displayed on
the instrument panel, let the transmission cool
down then wait for the display to clear before
setting off again.
If "4WD" and "LOCK" are displayed alternately
and if "SERVICE REQUIRED" is displayed in
the instrument panel, the system has failed and
the safety system has been activated.
Contact a CITROËN dealer or a qualified
workshop without delay. Have your vehicle towed on a
flatbed.
The vehicle must not be towed with the
front or rear wheels on the ground even
if it is in front "2WD" (2 wheel drive)
mode.If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.

Cruise control
System which automatically maintains the vehicle speed at the value programmed by the driver, without any action on the accelerator pedal.
The cruise control is switched on manually:
the vehicle speed must be at least 25 mph
(40 km/h) and second gear or higher must be
engaged in the case of a manual gearbox.
The cruise control is switched off manually, by
an action on the brake or clutch pedal or if the
ASC system is triggered.
The programmed speed can be exceeded
temporarily by pressing the accelerator pedal.
The cruise control cannot, in any
circumstances, take the place of the
need to comply with speed limits or of the
vigilance and responsibility of the driver. The controls of this system are grouped
together on the steering wheel.

Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-
a
nti-lock braking system (ABS),
-

e
lectronic brake force distribution (EBFD).
Braking assistance systems
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in particular on poor or slippery sur faces.
Activation
The anti-lock braking system is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.
Operating fault
When the vehicle is stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.
