Braking assistance systems
Group of supplementary systems which help you to obtain optimum braking in complete safety in emergency 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 par ticular on poor or slippery sur faces.
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.
When braking in an emergency, press very firmly without releasing the pressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABSwarning lamps, accompanied by an audible signal and a message on the multifunction screen, 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.
When replacing wheels (tyres and rims), ensure that they conform to the manufacturer's recommendations.
If this warning lamp comes on, accompanied by an audible signal and a message on the multifunction screen, it indicates a malfunction of the anti-lock braking system which could result in loss of control of the vehicle when braking.
In either case, contact a CITROËN dealer.

131Safety
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 efficiency.
When braking in an emergency, press firmly without releasing the pressure.
Trajectory control systems
Anti-skid regulation (ASR)
and electronic stability
programme (ESP)
The anti-skid regulation (also known as Traction Control) optimises traction 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, within the limits of the laws of physics.
Activation
These systems are activated automatically each time the vehicle is star ted. They come into operation in the event of a grip or trajectory problem.
This is indicated by flashing of this warning lamp on the instrument panel.

Parking brake
Applying
 Pull the parking brake lever fully up to immobilise your vehicle.
Releasing
 Pull the parking brake lever gently, press the release button then lower the lever fully.
When parking on a slope, direct your wheels against the pavement, apply the parking brake and engage a gear.
When the vehicle is being driven, if this warning lamp and the STOP warning lamp come on, accompanied by an
audible signal and a message on the multifunction screen, this indicates that the parking brake is still on or has not been properly released.

147Driving
Four-speed automatic gearbox which offers a choice between the comfor t of fully automatic operation, enhanced by spor t and snow programmes, or manual gear changing. Therefore, four driving modes are offered:
- automatic operation for electronic management of the gears by the gearbox, - spor t programme for a more dynamic style of driving, - snow programme to improve driving when traction is poor, - manual operation for sequential changing of the gears by the driver.
Automatic gearbox
1. Gear lever. 2. Button "S" (spor t) . 3. Button "" (snow).
Gear selection gate
P. Park. - Immobilisation of the vehicle, parking brake on or off. - Star ting the engine. R. Reverse. - Reversing manoeuvres, vehicle stationary,
engine at idle. N. Neutral. - Immobilisation of the vehicle, parking brake on.
- Star ting the engine. D. Automatic operation. M. +/- Manual operation with sequential
changing of the four gears. Push forwards to change up through the gears. or  Pull backwards to change down through the gears.

Displays on the instrument panel
Foot on brake
 Press the brake pedal when this indicator lamp is displayed on the instrument panel (e.g.: star ting the engine).
Moving off
If position N is engaged inadver tently while driving, allow the engine to return to idle then engage position D to accelerate.
When the engine is running at idle, with the brakes released, if position R , D or
M is selected, the vehicle moves even without the accelerator being pressed. When the engine is running, never leave children in the vehicle without super vision. When carrying out maintenance with the engine running, apply the parking brake and select position P . PP
 Apply the parking brake.  Select position P or N .  Star t the engine. If this procedure is not followed, an audible signal is heard, accompanied by a message on the multifunction screen.  With the engine running, press the brake pedal.  Release the parking brake.  Select position R , D or M ,  Gradually release the brake pedal. The vehicle moves off immediately.

Manual operation
D disappears and the gears engaged appear in succession on the instrument panel. In the event of the engine labouring or over-revving, the gear selected flashes for a few seconds, then the actual gear engaged is displayed.
It is possible to change from position D(automatic) to position M (manual) at any time. When the vehicle is stationary or moving very slowly, the gearbox selects gear M1automatically. The spor t and snow programmes do not operate in manual mode.
Invalid value during manual operation
 Select position M for sequential changing of the four gears.  Push the lever towards the + sign to change up a gear.  Pull the lever towards the - sign to change down a gear. It is only possible to change from one gear to another if the vehicle speed and engine speed permit; other wise, the gearbox will operate temporarily in automatic mode.
This symbol is displayed if a gear is not engaged correctly (selector between two positions).
Stopping the vehicle
Before switching off the engine, you can engage position P or N to place the gearbox in neutral. In both cases, apply the parking brake to immobilise the vehicle.
When the ignition is on, the lighting of this warning lamp,
accompanied by an audible signal and a message on the multifunction screen, indicates a gearbox malfunction. In this case, the gearbox switches to back-up mode and is locked in 3rd gear. You may feel a substantial knock when changing from P to R and from RN to R . RRThis will not cause any damage to the gearbox. Do not exceed 60 mph (100 km/h), local speed restrictions permitting. Contact a CITROËN dealer as soon as possible.
Operating fault
If the lever is not in position P , Pwhen the driver's door is opened or approximately 45 seconds after the ignition is switched off, a message appears in the multifunction screen.  Return the lever to position P ; the
message disappears.
There is a risk of damage to the gearbox: - if you press the accelerator and
brake pedals at the same time, - if you force the movement of the gear lever from the P position to
another position when the battery is flat.
To reduce fuel consumption when at a prolonged standstill with the engine running (traffic jam...), put the gear lever in the N position and apply the parking brake.
