Manual gearbox
Automatic gearbox
Brake pads
Brake wear depends on the style of driving, par ticularly in the case of vehicles used in town, over shor t distances. It may be necessary to have the condition of the brakes checked, even between vehicle ser vices. Unless there is a leak in the circuit, a drop in the brake fluid level indicates that the brake pads are worn.
The gearbox does not require any maintenance (no oil change). Refer to the Maintenance and Warranty Guide for the details of the level checking inter val for this component.
Brake disc wear
Parking brake
If a loss of effectiveness of this system is noticed, the parking brake must be checked, even between two ser vices. This system must be checked by a CITROËN dealer.
Only use products recommended by CITROËN or products of equivalent
quality and specifications. In order to optimise the operation of units as impor tant as the braking
system, CITROËN selects and offers very specific products. To avoid damaging the electrical units, the use of a high pressure washer
in the engine compar tment is strictly prohibited .
The gearbox does not require any maintenance (no oil change).
Refer to the Maintenance and Warranty Guide for details of the level checking inter val for this component.
For information relating to checking the brake disc wear, contact a
CITROËN dealer.

177Practical information
1. Sealing
 Uncoil the white pipe G fully.  Unscrew the cap from the white pipe.
 Connect the white pipe to the valve of the tyre to be repaired.
Repair procedure
Avoid removing any foreign bodies which have penetrated into the tyre.
 Connect the compressor’s electric plug to the vehicle’s 12 V socket.
 Star t the vehicle and leave the engine running.
 Switch off the ignition.  Turn the selector A to the "SEALANT"
position.  Check that the switch B is in position "O" .
Take care, this product is harmful (e.g. ethylene-glycol, colophony...) if swallowed and causes irritation to the eyes. Keep it out of reach of children.

Removing the cartridge
 Stow the black pipe.  Detach the angled base from the white pipe.  Suppor t the compressor ver tically.  Unscrew the car tridge from the bottom.
Checking tyre pressures/
inflating accessories
Beware of discharges of fluid. The expiry date of the fluid is indicated
on the car tridge. The sealant car tridge is designed for single use; even if only par tly used, it must be replaced. After use, do not discard the cartridge into the environment, take it to an authorised waste disposal site or a CITROËN dealer. Do not forget to obtain a new sealant car tridge, available from CITROËN dealers.
You can also use the compressor, without injecting any product, to: - check or adjust the pressure of your tyres, - inflate other accessories.
 Connect the compressor’s electrical connector to the vehicle’s 12 V socket.  Star t the vehicle and let the engine run.  Adjust the pressure using the compressor (to inflate: switch B in position "I" ; to deflate: switch B in position "O" and press button C ), according to the vehicle’s tyre
pressure label or the accessory’s pressure label.  Remove the kit then stow it.
 Turn the selector A to the "Air"
position.  Uncoil the black pipe H fully.
 Connect the black pipe to the valve of the wheel or accessory. If necessary, fit one of the adaptors supplied with the kit first.

203Practical information
 Connect one end of the green or black cable to the negative terminal (-) of the slave battery B .  Connect the other end of the green or black cable to the negative terminal (-) of the flat battery A .
 Star t the slave vehicle.  Operate the star ter of the broken down
vehicle and let the engine run.  Wait until the engine returns to idle and disconnect the cables.
Charging the battery using
a battery charger
Batteries contain harmful substances such as sulphuric acid and lead. They must be disposed of in accordance with regulations and must not, in any circumstances, be discarded with household waste. Take used remote control batteries and vehicle batteries to a special collection point.
 Disconnect the battery from the vehicle.
 Follow the instructions for use provided by the manufacturer of the charger.  Reconnect star ting with the negative terminal (-).  Check that the terminals and connectors are clean. If they are covered with sulphate (whitish or greenish deposit), remove them
and clean them.
The Stop & Star t battery does not have to be disconnected for charging. It is advisable to disconnect the battery if the vehicle is to be left unused for more than one month.

209Practical information
The rear parking sensors will be deactivated automatically if a genuine
CITROËN towbar is used.
Driving advice
Distribution of loads
 Distribute the load in the trailer so that the heaviest items are as close as possible to the axle and the nose weight approaches the maximum permitted without exceeding it. Air density decreases with altitude, thus reducing engine per formance. Above 1 000 metres, the maximum towing load must be reduced by 10 % and so on for every 1 000 metres of altitude. Refer to the "Technical Data" section for details of the weights and towing loads which apply to your vehicle.
Side wind
 Take into account the increased sensitivity to side wind.
Cooling
Towing a trailer on a slope increases the temperature of the coolant. As the fan is electrically controlled, its cooling capacity is not dependent on the engine speed.  To lower the engine speed, reduce your speed. The maximum towing load on a long slope depends on the gradient and the ambient temperature. In all cases, pay attention to the coolant temperature.
Braking
Towing a trailer increases the braking distance.
Tyres
 Check the tyre pressures of the towing vehicle and of the trailer, obser ving the recommended pressures.
Lighting
 Check the electrical lighting and signalling on the trailer.
 If the warning lamp and the STOP warning lamp come on, stop the vehicle and switch off
the engine as soon as possible.

251QUESTIONANSWERSOLUTION
The stored stations do not function (no sound, 87.5 Mhz is displayed...) An incorrect waveband is selected. Press the BAND AST button to return to the waveband (AM, FM1, FM2, FMAST) on which the stations are stored.
The quality of reception of the radio station listened to gradually deteriorates or the stored stations do not function (no sound, 87.5 Mhz is displayed...).
The vehicle is too far from the transmitter used by the station listened to or there is no transmitter in the geographical area through which the vehicle is travelling.
Activate the RDS function to enable the system to check whether there is a more powerful transmitter in the geographical area.
The environment (hills, buildings, tunnels, basement car parks.. .) block reception, including in RDS mode. This phenomenon is normal and does not indicate a failure of the audio equipment.
The aerial is absent or has been damaged (for example when g oing through a car wash or into an underground car park). Have the aerial checked by a CITROËN dealer.
Sound cut-outs of 1 to 2 seconds in radio mode. During this brief sound cut-out, the RDS searches for any freque ncy permitting better reception of the station. Deactivate the RDS function if the phenomenon is too frequent and always on the same route.
With the engine off, the audio equipment switches off after a few minutes of use.
When the engine is switched off, the audio equipment operating time depends on the battery charge.
The switch-off is normal: the audio equipment switches to eco nomy mode and switches off to prevent discharging of the vehicle's battery.
Start the vehicle's engine to increase the battery charge.
