INSTRUMENTS and CONTROLS
The warning lights may come on
continuously or fl ash.
Certain warning lights may come
on in two different modes. Only by
relating the type of lighting to the
operating status of the vehicle can
it be ascertained whether the situ-
ation is normal or whether a fault
has occurred.
Indicator and warning lights
Visual indicators informing the driver
that a system is in operation (operation
or deactivation indicator lights) or of the
occurrence of a fault (warning light).
Associated warnings
The switching on of certain warning lights
may be accompanied by an audible signal
and a message on the multifunction display.
Operation indicator lights
If one of the following indicator lights comes on, this co
nfi rms that the correspond-
ing system has come into operation.
Left-hand direction indicator.
Sidelamps.
Handbrake applied.
Main beam headlamps.
Dipped headlamps.
Front fog lamps.
Coolant temperature.
If lit, this indicates that the en-
gine is cool. Right-hand direction
indicator.
When the ignition is switched on
The warning lights come on for a few
seconds when the vehicle's ignition is
switched on.
When the engine is started, these warn-
ing lights should switch off.
If they remain on, before moving off,
consult the warning light concerned.
Diesel engine pre-heating.

INSTRUMENTS and CONTROLS
When the engine is running or the vehi-
cle is moving, the lighting of one of the
following warning lights indicates the
occurrence of a fault requiring interven-
tion on the part of the driver.
Central alert.
Lighting is associated with
the displaying of another
warning light:
- braking,
- power steering,
- engine oil pressure,
- coolant temperature,
stop the vehicle immediately and as
safely as possible. Service.
If this comes on, it indicates
the occurrence of a problem
in one of the systems which
does not have a specifi c
warning light.
In order to identify it, consult the mes-
sage on the multifunction display.
Check:
- the engine oil level,
- the screenwash fl uid level,
- the remote control battery,
- the condition of the bulbs.
For any other situations, contact a
CITROËN dealer.
The illumination of this warning light
may also indicate that the (Diesel) par-
ticle fi lter is starting to get clogged up,
due to specifi c extended urban driving
conditions: low speed, congestion, etc.
In order to regenerate the fi lter, you are
advised to drive, once traffi c conditions
allow, at a speed of 40 mph (60 km/h)
or above for at least 5 minutes (until the
warning light goes out). Braking.
If this comes on, it indicates the
occurrence of a fault in one of
the braking systems:
- signifi cant drop in the level in the circuit,
- electronic brake force distribution (EBFD) faulty (simultaneous lighting
of the ABS warning light),
stop the vehicle immediately and as
safely as possible.
When the vehicle is moving, check that
the handbrake is fully released.
Any fault resulting in the displaying
of a warning light must be the sub-
ject of further diagnostics by read-
ing the associated message on the
multifunction display.
Should you encounter any prob-
lems, do not hesitate to contact a
CITROËN dealer.
Warning lights
Anti-lock braking system
(ABS).
If this comes on, it indicates the
occurrence of a fault in the anti-
lock braking system.
However, this does not prevent opera-
tion of the vehicle's assisted braking.
Dynamic stability control
(ESP/ASR).
The ESP/ASR system is put
into service automatically when
the vehicle is started.
Unless the system has been deactivated,
if this warning light and the indicator light
on the button come on continuously, this
indicates the occurrence of a fault in the
ESP/ASR system.
If the warning light remains on,
contact your CITROËN dealer.

BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situations:
- the anti-lock braking system (ABS),
- the electronic brake force distribu-tion (EBFD),
- the emergency braking assistance (EBA).
Anti-lock braking system and electronic brake force distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.
When braking in an emergency,
press very fi rmly without releasing
the pressure. When replacing wheels (tyres and
rims), ensure that they conform to
the manufacturer’s recommenda-
tions.
Operating fault
If this warning light comes on,
accompanied by an audible
signal and a message on the
multi-function display, it indicates
a malfunction of the anti-lock braking sys-
tem which could result in loss of control of
the vehicle when braking.
If this warning light comes on,
together with the STOP and

ABS warning lights, accompa-
nied by an audible signal and a
message on the multifunction display, it
indicates a malfunction of the electronic
brake force distribution which could
result in loss of control of the vehicle
when braking.

You must stop as soon as it is safe
to do so.
Emergency braking assistance
System which, in an emergency, ena-
bles you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.
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. 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.
In both cases, contact a CITROËN
dealer. When braking in an emergency,
press fi rmly without releasing the
pressure.

The ESP/ASR systems offer ex-
ceptional safety in normal driving,
but this should not encourage the
driver to take extra risks or drive at
high speed.
The correct functioning of these
systems depends on observation
of the manufacturer's recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.
Disarming
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to disarm the ASR and ESP
systems, so that the wheels can move
freely and regain grip.
 Press the "ESP OFF" button, locat-
ed in the centre of the fascia.
If this warning light comes on on
the instrument panel and the in-
dicator light on the button comes
on, this indicates that the ASR
and ESP systems are disarmed.
Reactivation
These systems are reactivated automat-
ically each time the ignition is switched
back on or from 30 mph (50 km/h).

 Press the "ESP OFF" button again
to reactivate them manually. Operating fault
If this warning light comes on,
accompanied by an audible sig-
nal and a message on the multi-
function display, this indicates a
malfunction of these systems.
Have the systems checked by a
CITROËN dealer.
TRAJECTORY CONTROL SYSTEMS
Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
of a grip or trajectory problem.
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme acts
on the brake of one or more wheels and
on the engine to keep the vehicle on the
trajectory required by the driver.
This is indicated by fl ashing of
this warning light on the instru-
ment panel.

your wheels against the pavement,
pull the handbrake and engage a
gear.
HANDBRAKE
Mechanical brake to hold the vehicle
when stationary.
Applying

 Pull the handbrake to immobilise
your vehicle. When the vehicle is being driven,
if this warning light and the
STOP
warning light come on, accompa-
nied by an audible signal and a
message on the multi-function display,
this indicates that the handbrake is still on
or has not been properly released.
Releasing

 Pull on the handle and press the
button A to release the handbrake.

DRIVING
CRUISE CONTROL
System which automatically maintains
the speed of the vehicle at the value
programmed by the driver, without any
action on the accelerator pedal.
The cruise control is switched on
manually: it requires a minimum vehicle
speed of 25 mph (40 km/h) and the
engaging of at least 4th gear.
The controls of this system are grouped
together on lever A .

1. Cruise control mode selection dial

2. Speed programming/value decrease
button

3. Speed programming/value increase
button

4. Cruise control off/resume button The programmed information is grouped
together on the instrument panel display.

5. Cruise control off/resume indication

6.
Cruise control mode selection indication

7. Programmed speed value
Steering wheel controls Displays on the instrument
panel
The cruise control cannot, in any
circumstances, replace the need
to respect speed limits, nor can it
replace the need for vigilance and
responsibility on the part of the
driver.
The cruise control is
switched off
manually or by pressing the brake or
clutch pedal or on triggering of the ESP
system for safety reasons.
It is possible to exceed the programmed
speed temporarily by pressing the
accelerator pedal.
To return to the programmed speed,
simply release the accelerator pedal.
Switching off the ignition cancels any
programmed speed value.

CHECKS
CHECKING LEVELS Brake fluid level
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or us-
ing the dipstick.
Between two oil changes, the consump-
tion should not exceed 0.5 litre per
600 miles (1,000 km). The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Draining the circuit
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Coolant level The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the igni-
tion off.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
up or replaced with water.
Draining the engine
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil specifi cation
The oil must correspond to your engine
and conform to the manufacturer's recom-
mendations. Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
fulfi l the DOT4 standards.
Fluid specifi cation
The coolant must conform to the manu-
facturer's recommendations.
Draining the circuit
The coolant does not have to be
changed.
Screenwash fluid level
Top up the level when neces-
sary.
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the
corresponding circuit checked by a
CITROËN dealer.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

CHECKS Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
Brake disc wear status
Brake pads Handbrake Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short distances. It
may be necessary to have the
condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn. For information relating to
checking the brake disc wear
status, contact a CITROËN
dealer.
If the handbrake travel is too
long or if a loss of effective-
ness of this system is no-
ticed, the handbrake must be
adjusted, even between two
services.
This system must be checked by a
CITROËN dealer.
Manual gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the Maintenance and
Warranty Guide for the details
of the checking interval for this
component.
