Load reduction mode
System which manages the use of cer tain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
cer tain functions, such as the air conditioning,
the heated rear screen...
The deactivated functions are reactivated
automatically as soon as conditions permit. Do not disconnect the terminals while the engine is running.
Do not charge the batteries without disconnecting the terminals first.
Do not push the vehicle to star t the engine if it is fitted with the 6 -speed electronic
gearbox system.

Before disconnecting the
battery
Wait 2 minutes after switching off the
ignition before disconnecting the battery.
Close the windows and the doors before
disconnecting the battery.


Following reconnection
of the battery
Following reconnection of the battery,
switch on the ignition and wait 1 minute
before star ting to permit initialisation of the
electronic systems. However, if problems
are encountered following this operation,
contact a CITROËN dealer or a qualified
workshop.
Referring to the corresponding section,
you must yourself reinitialise:


- the remote control key,

- the GPS satellite navigation system.

Energy economy mode
System which manages the period of use of cer tain functions to conser ve a sufficient level of charge in the battery.
After the engine has stopped, you can still use functions such as the audio equipment, windscreen wipers, dipped beam headlamps, cour tesy lamps,
etc. for a maximum combined period of thirty minutes.
This period may be greatly reduced if
the battery is not fully charged.
A flat battery prevents the engine from
starting (refer to the corresponding
paragraph). If the telephone is being used at the
same time on the navigation system,
it will be interrupted after 10 minutes.


Switching to economy mode

Once this period has elapsed, a message
appears in the 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.

General
recommendations
Obser ve the legislation in force in your
country.
Ensure that the weight of the towing
vehicle is higher than that of the towed
vehicle.
The driver must stay at the wheel of the
towed vehicle.
Driving on motor ways and fast roads is
prohibited when towing.
When towing a vehicle with all four
wheels on the ground, always use an
approved towing bar; rope and straps
are prohibited.
When towing a vehicle with the engine
off, there is no longer any power
assistance for braking or steering. In the following cases, you must always call
on a professional recovery ser vice:


- vehicle broken down on a motor way or
fast road,

- when it is not possible to put the gearbox
into neutral, unlock the steering, or release
the parking brake,

- towing with only two wheels on the
ground,

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 or a
qualified workshop.
If the towbar is not fitted by a CITROËN
dealer, it is imperative that it is
fitted in accordance with the vehicle
manufacturer's instructions.
Driving with a trailer places greater demands
on the towing vehicle and the driver must take
particular care.

277Practical 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 towed load must
be reduced by 10 % for every 1 000 metres of
altitude.
Refer to the "Technical Data" section for details
of the weights and towed 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 towed load on a long incline
depends on the gradient and the ambient
temperature.
In all cases, keep a check on the coolant
temperature.

Braking

Towing a trailer increases the braking distance.
To avoid overheating of the brakes on a long
mountain type of descent, the use of engine
braking is recommended.


Ty r e s



)
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.
