Advice on child seats
The incorrect installation of a child seat in a vehicle compromises the child's protection in the event of an accident. Remember to fasten the seat belts or the child seat harnesses keeping the slack relative to the child's body to a minimum, even for shor t journeys. When installing a child seat using the seat belt, ensure that the seat belt is tightened correctly on the child seat and that it secures the child seat firmly on the seat of your vehicle. Move the seat for wards if necessary. For optimum installation of the "for wards-facing" child seat, ensure that the back of the child seat is in contact with the back of the vehicle's seat and that the head restraint does not cause any discomfor t. If the head restraint has to be removed, ensure that it is stored or attached securely to prevent it from being thrown around the vehicle in the event of sharp braking.
Children under the age of 10 must not travel in the "for wards-facing" position on the front passenger seat, unless the rear seats are already occupied by other children, cannot be used or are absent. Deactivate the passenger airbag when a "rear wards-facing" child seat is installed on the front seat. Other wise, the child would risk being seriously injured or killed if the airbag were to inflate.
Installing a booster seat
The chest par t of the seat belt must be positioned on the child's shoulder without touching the neck.
Ensure that the lap par t of the seat belt passes correctly over the child's thighs. CITROËN recommends the use of a booster seat which has a back, fitted with a seat belt guide at shoulder level.
As a safety precaution, do not leave: - a child or children alone and unsuper vised in a vehicle, - a child or an animal in a vehicle which is exposed to the sun, with the windows closed, - the keys within reach of children inside the vehicle. To prevent accidental opening of the doors
and rear windows, use the "Child lock". Take care not to open the rear windows by more than one third. To protect young children from the rays of the sun, fit side blinds on the rear windows.

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 in 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 in 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 or a qualified workshop.

255Practical information
1. Brake lamps (P21/5W).2. Sidelamps (LEDs).3. Direction indicators (PY21W amber)4. Reversing lamp (P21W).
5. Rear foglamps (P21W).
Rear lamps
Amber bulbs, such as those for the
direction indicators, must be replaced by bulbs of the same rating and colour. The lamps on the tailgate, other than
the guide lamps, are dummy units. They are there for aesthetic purposes only.
Changing stop lamp, reversing lamp and direction indicator bulbs
These three bulbs are changed from inside the boot:
 open the boot,  remove the access grille from the
corresponding side trim panel,  slacken the two nuts using a 10 mm tube
spanner then remove the nuts by hand,  unclip the lamp unit connector,  extract the lamp unit carefully pulling in its middle towards the outside,
 remove the foam seal,  unclip the two small secondary connectors,
 spread the two tabs and remove the bulb holder,
 turn the bulb a quarter of a turn and change it. To reassemble, carry out these operations in reverse order. Take care to engage the lamp unit in its guides, while keeping it in line with the vehicle. Tighten sufficiently to ensure sealing, but without damaging the lamp.

269Practical information
 On the front bumper, unclip the cover by pressing at the bottom.  Screw the towing eye in fully.  Install the towing bar.
 On the rear bumper, unclip the cover by pressing at the bottom.  Screw the towing eye in fully.  Install the towing bar.  Switch on the hazard warning lamps on both vehicles.  Move off gently, drive slowly and for a shor t distance.
Towing your vehicle Towing another vehicle
 Place the gear lever in neutral (position N on the electronic gearbox system). Failure to obser ve this special condition could result in damage to cer tain components (braking, transmission...) and the absence of braking assistance the next time the engine is star ted.
 Unlock the steering by turning the key in the ignition one notch and release the
parking brake.  Switch on the hazard warning lamps on both vehicles.
 Move off gently, drive slowly and for a shor t distance.
