This is confirmed by an audible signal and the
lighting of the corresponding direction indicator
lamp on the instrument panel.
► To switch off the parking lamps, return the lighting control stalk to the central position.
Automatic illumination of
headlamps
When the ring is at the "AUTO" position and
a low level of ambient light is detected by a
sunshine sensor, the number plate lamps, side lamps and dipped beam headlamps are switched
on automatically, without any action on the
part of the driver. They can also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the light returns to a sufficient level
or after the windscreen wipers are switched off,
the lamps are switched off automatically.
Operating fault
In the event of a malfunction of the sunshine sensor, the lighting comes on,
this warning lamp is displayed in the instrument
panel accompanied by an audible signal and/or a

should only be used in fog or falling snow.
In these weather conditions, it is your
responsibility to switch on the foglamps and
dipped beam headlamps manually as the
sunshine sensor may detect sufficient light.
Do not forget to turn off the front and rear
foglamps as soon as they are no longer
necessary.
Switching off of the lamps when the
ignition is switched off
When the ignition is switched off, all of the
lamps turn off immediately, except for dipped
beam headlamps if automatic guide-me-home
lighting is activated.
Switching on the lamps after
switching off the ignition
To reactivate the lighting control, rotate the
ring to the "AUTO" position, then to the
desired position.
If the driver's door is opened, a temporary
audible signal warns the driver that the lamps

Practical information
► Refit protective plug 2 to carrier 1.► Carefully stow the towball in its bag away from knocks and dirt.
Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure
jet wash, the towball must be removed and the
protective plug fitted to the carrier.
Apply the label provided to a clearly visible area, close to the carrier or in the
boot.
Go to a CITROËN dealer or a qualified
workshop for any work on the towbar system.
Towing device
Load distribution► 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 performance. The maximum load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it
must still be fitted in accordance with the
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country where you are driving.
Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates certain
functions, such as air conditioning, heated rear
screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched to
economy mode and the active functions are put
on standby.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free system
of your audio system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
– For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the
12 V battery,
refer to the corresponding section.
Roof bars
For safety reasons and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
Observe the fitting instructions and the
conditions of use in the guide supplied
with the roof bars.
