Practical information
– the green mark on the star wheel is in line
with the white mark on the ball joint,
– the locking wheel is in contact with the towball (position A),– the security key lock is on and the key removed; the locking wheel can no longer be
operated,
– the towball must not be able to move in its carrier; test by shaking it with your hand.
If the towball is not locked, the trailer can
detach - accident risk!
During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the maximum authorised
weight for the vehicle - the Gross Train
Weight or GTW.
It is essential that the maximum authorised
load be complied with on the towing device:
if it is exceeded, this device may detach from
the vehicle, which is a serious accident risk.
Check that the trailer lamps work correctly.
Before setting off, check the adjustment of the
headlamp beam height.
For more information on Headlamp
adjustment, refer to the corresponding
section.
Following use
When travelling without a trailer or load
on a towbar-mounted carrier, the towball
must be removed and the protective plug
inserted in the carrier. This measure applies
particularly where the towball might obscure
visibility of the number plate or its lighting.
Fitting the towball

► Below the rear bumper , remove the protective plug 2 from the towball carrier 1.

► Insert the end of towball 5 into carrier 1 and
push it upwards; the locking will take place
automatically.


► The locking wheel 6 turns a quarter of a turn
anti-clockwise ; take care to keep your hands
clear!


► Check that the mechanism has correctly locked into place and that the green mark on the
star wheel is in line with the white mark on the
towball (position A).
► Close the lock 7 using the key.

128
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.
