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 must still be 
fitted in accordance with the vehicle 
manufacturer's instructions.
Your vehicle is primarily designed for 
transporting people and luggage, but it may 
also be used for towing a trailer. Driving with a trailer places greater 
demands on the towing vehicle and the 
driver must take particular care.
For more advice on driving when 
towing, refer to the corresponding 
section.
For more information on weights (and 
the towed loads which apply to your 
vehicle) refer to the corresponding 
section.

section.

- t he towball is correctly locked in place (position A ),
-
 
t
 he security key lock is on and the key removed; the locking wheel can no longer be

Before driving, check the adjustment of the headlamp beam height.
For more information on adjusting the headlamps, refer to the corresponding section.
After use
For journeys made without a trailer or load carrier, the trailer harness socket must be folded 
away, the towball removed and    the blanking plug inserted in the carrier. This measure 
applies particularly if the towball could hinder visibility of the number plate or lighting.

and check the condition of the fixing system. 
If necessary, clean the carrier with a brush or 
clean cloth.

If not, insert the key in the lock and turn the key 
anti-clockwise to unlock the mechanism.

If the key cannot be turned or removed, 
this means that the towball is not fitted 
correctly; start the procedure again.
If one of the locking conditions is not 
met, start the procedure again.
In all cases, if the marking remains 
red, do not use the towbar and contact 
a CITROËN dealer or a qualified 
workshop.
Take the towball in both hands; insert the end 
of the towball into the carrier by lifting it, then, 
to ensure that it has correctly locked in place, 
pull firmly down on the ball end of the towball.

of a turn anti-clockwise, making a perceptible 
click; take care to keep your hands clear.
