Practical information
7► Remove the cap from the lock and press it
onto the head of the key .


► Insert the key into the lock 7.
► Open the lock using the key .


► Hold the towball 5 firmly in one hand; using
the other hand, pull and turn the wheel 6 fully in
a clockwise direction until it stops; do not release
the wheel.
►

Extract the towball from the base of its
carrier

1.
► Release the wheel; it automatically locks in
the unlocked position (position B
).


► Replace the protective plug 2 into the
carrier 1.
►

Stow the towball in its bag to protect it 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.
Work on the towing device
Contact a CITROËN dealer or a qualified
workshop.
Roof bars
As a safety measure and to avoid damaging the roof, it is essential to use
transverse roof bars approved for your
vehicle.
Observe the instructions on fitting and use
contained in the guide supplied with the roof
bars.
Maximum load distributed over the
transverse roof bars, for a loading height
not exceeding 40 cm (except bicycle carrier):
80

kg.
As this value may change, please verify the
maximum load quoted in the guide supplied
with the roof bars.
If the height exceeds 40 cm, adapt the speed
of the vehicle to the profile of the road to
avoid damaging the roof bars and the fixings
on the vehicle.
Be sure to refer to national legislation in order
to comply with the regulations for transporting
objects that are longer than the vehicle.
Recommendations
Distribute the load uniformly, taking care
to avoid overloading one of the sides.
Arrange the heaviest part of the load as close
as possible to the roof.
Secure the load firmly.

168
Practical information
Drive gently: the vehicle will be more
susceptible to the effects of side winds and its
stability may be affected.
Regularly check the security and tight
fastening of the roof bars, at least before each
trip.
Remove the roof bars once they are no longer
needed.
Sunroof
Check that the load does not pass below
the roof bars so that it does not impede the
movements of the sunroof - risk of major
damage!
Direct fitting on roof

The transverse bars must only be fixed at the
four anchorage points located on the roof frame.
These points are concealed by the vehicle doors
when the doors are closed.
The roof bar fixings have a stud which must be
inserted into the opening of each anchorage
point.
Snow chains
In wintry conditions, snow chains improve
traction as well as the behaviour of the vehicle
when braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Observe the legislation in force in your
country relating to the use of snow
chains and maximum authorised speeds.
Use only chains designed to be fitted to the type
of wheel fitted to the vehicle:
Original tyre size Chain type 215/65 R16 Polaire XP9 120
(9
mm)
215/60 R17 Polaire XP9 120
(9
mm)
195/60 R18 Polaire PSS 112
(10
mm)
For more information on snow chains, contact a
dealer or a qualified workshop.
Installation tips
► To fit the snow chains during a journey, stop
the vehicle on a flat surface at the side of the
road.
►

Apply the parking brake and position any
wheel chocks under the wheels to prevent
movement of the vehicle.
►


Fit the snow chains following the instructions
provided by the manufacturer

.
►

Move off gently and drive for a few moments,
without exceeding 31

mph (50 km/h).
►

Stop the vehicle and check that the snow
chains are correctly tightened.
It is strongly recommended that you
practise fitting the snow chains on a level
and dry surface before setting off.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.
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 and for a maximum
cumulative period of around 30 minutes, you can
