lamp on the display informs
you that you need to press
the brake pedal in order to
be able to start the engine on a ve-
hicle with the (6-speed) Electronic
Gearbox System, or to move out of
position P in the case of an automatic
gearbox.
It may also fl ash to prompt you to
brake when engaging reverse gear.
In the case of the Electronic Gearbox
System, this warning lamp fl ashes to
indicate overheating of the clutch if
you use the accelerator excessively
to hold the vehicle on an uphill slope.

This warning lamp is displayed
a few seconds after the func-
tion is activated. Deactivation warning lamps
If one of the following warning lamps
comes on, this confi rms that the
corresponding system has been
switched off intentionally.
Passenger's airbag system
deactivation
Dynamic stability control
(ESP/ASR) deactivation
The ESP/ASR system is put
into service automatically
when the vehicle is started.
A specifi c button, located on the
dashboard, permits deactivation of
the system. This is confi rmed by
continuous lighting of this warning
lamp and of the indicator lamp on
the button.
From approximately 30 mph (50 km/h),
the system is reactivated automatically. Warning lamps
Diesel engine pre-heating
Wait until this has gone out
before operating the starter.
When the engine is running or the
vehicle is moving, the lighting of
one of the following warning lamps
indicates the occurrence of a fault
requiring action on the part of the
driver.
Any fault resulting in the displaying of
a warning lamp must be investigated
further by reading the associated mes-
sage on the multifunction screen.
Should you encounter any problems,
do not hesitate to contact a CITROËN
dealer.
The passenger's airbag sys-
tem is put into service auto-
matically when the vehicle is
started.

bars are lit.
If the fuel low warning lamp
comes on accompanied by
an audible signal and a message on
the multifunction screen, there are
approximately 7 litres of fuel remain-
ing in the tank and the 2 or 3 bars
fl ash on the instrument panel.
When the last bar goes out, there

BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD),
- emergency braking assistance (EBA).
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 surfaces.
Activation
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 braking in an emergency,
press very fi rmly without releasing
the pressure. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
it indicates a malfunction of the anti-
lock braking system which could re-
sult in loss of control of the vehicle
when braking.
If this warning lamp comes
on, together with the STOP
and ABS warning lamps,
accompanied by an audible
signal and a message on the multi-
function screen, it indicates a mal-
function of the electronic brake force
distribution which could result in loss
of control of the vehicle when brak-
ing.

You
must
stop as soon as it is
safe to do so.
In either case, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to
the manufacturer's recommenda-
tions.
Emergency braking assistance
System which, in an emergency,
enables you to obtain the optimum
braking pressure more quickly, thus
reducing the stopping distance.
Activation
It is triggered by the speed at which
the brake pedal is pressed.
The effect of this is a reduction in
the resistance of the pedal and an
increase in braking effi ciency.
When braking in an emergency,
press fi rmly without releasing the
pressure.

Displays on the instrument panel
- The selector position is displayed in the instrument panel, on the left
on multifunction screens A and C
and on the right on the NaviDrive
multifunction screen.
- A back-lit position grille associ- ated with the selector shows the
position selected. Moving off

When the ignition is on, lighting of
the service warning lamp, accom-
panied by an audible signal and
the message "Gearbox faulty" in-
dicates a malfunction.
Consult a CITROËN dealer.
For safety:

 Position N can only be disen-
gaged if you are pressing the
brake pedal.

 If the gearbox is in position N
but the selector position is differ-
ent, reposition the selector on N
in order to be able to start.
 To start the engine, the selector
must be in position N .

 Press fi rmly on the brake pedal.

 Operate the starter.

 When the engine is running,
place the selector on R , A or M
as desired.

 Check, in the instrument panel,
the position engaged.

 Release the brake pedal and
accelerate.
If the selector is not in position N ,
and/or if the brake pedal is not
pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
Engaging reverse gear
To engage reverse gear, move the
selector to R .

Only attempt to select reverse gear
when the vehicle is stationary.
If the vehicle is moving rapidly, if an in-
advertent attempt to engage reverse
gear is made, the warning lamp N will
fl ash and your vehicle will go auto-
matically into neutral. To re-engage a
gear, you have only to reposition the
selector on A , M or R .
