Do not disconnect the terminals while the engine is running. Do not charge the batteries without disconnecting the terminals first.

205Practical information
Energy economy mode
System which manages the period of use of cer tain fu nctions to conser ve a sufficient level of charge in the battery. After the engine has stopped, you can still use func tions such as the audio equipment, windscreen wipers, dipped beam headlamps, cour tesy lamps, etc. for a maximum combined period of thir ty mi nutes.
This period may be greatly reduced if the battery is not fully charged.
A flat battery prevents the engine from star ting (refer to the corresponding paragraph).
If the telephone is being used at the same time on the MyWay audio navigation system, it will be interrupted after 10 minutes.
Switching to economy mode
Once this period has elapsed, a message
appears on the multifunction screen indicating that the vehicle has switched to economy mode and the active functions are put on standby.
Exiting economy mode
These functions are reactivated automatically
the next time the vehicle is driven.  In order to resume the use of these functions immediately, star t the engine and let it run for a few minutes. The time available to you will then be double the period for which the engine is left running. However, this period will always be between five and thir ty minutes.

Changing a front or rear wiper blade Procedure for replacing a worn wiper blade with a new one without the use of tools.
Before removing a front
wiper blade
 Within one minute after switching off the ignition, operate the wiper stalk to position the wiper blades in the ver tical position. This position must be used in order to avoid damaging the wiper blade and the bonnet.
Removal
 Raise the corresponding wiper arm.  Unclip the wiper blade and remove it.
Fitting
 At the front, check the size of the wiper blade as the shor ter blade is fitted to the passenger side of the vehicle.  Put the corresponding new wiper blade in place and clip it.  Fold down the wiper arm carefully.
After fitting a front wiper
blade
 Switch on the ignition.  Operate the wiper stalk again to park the wiper blades.

207Practical information
Towing the vehicle
Procedure for having your vehicle towed or for towing another vehicle using a removable towing eye.
The towing eye is installed in the boot under the floor. To gain access to it:  open the boot,  raise the floor,
 remove the polystyrene storage box,  remove the towing eye from the holder.
 On the front 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 the towed vehicle.  Place the gear lever in neutral (position Nfor an automatic gearbox).
 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 the towed vehicle.
Towing your vehicle Towing another vehicle Access to the tools
Failure to obser ve this special condition could result in damage to cer tain braking components and the absence of braking assistance the next time the engine is star ted.
When towing with all four wheels on the
ground, always use a towing bar. When towing with only two wheels on the ground, always use professional
lifting equipment. When towing with the engine off, there is no longer any assistance for braking or steering.

Towing a trailer, a caravan, etc.
Towbar suitable for the attachment of a trailer or caravan with additional lighting and signalling. Your vehicle is primarily designed for transpor ting people and luggage, but it may
also be used for towing a trailer.
We recommend the use of genuine CITROËN towbars and their harnesses that have been tested and approved from the design stage of your vehicle,
and that the fitting of the towbar is entrusted to a CITROËN dealer. If the trailer is not fitted by a CITROËN dealer, it is imperative that it is fitted using the electrical pre-equipment installed at the rear of the vehicle, in accordance with the manufacturer's instructions.
Driving with a trailer subjects the towing vehicle to more significant stress and its driver must be par ticularly careful.

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.
