When towing
Distribution of loads
F 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.
Side wind
F Take into account the increased sensitivity to side wind.For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
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.
F
T
o lower the engine speed, reduce your
speed.
The maximum towed load on a long incline
depends on the gradient and the exterior
temperature.
In all cases, keep a check on the coolant
temperature.
F

I
f the warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
Braking
Towing a trailer increases the braking distance.
To avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.

Electric parking brake
In the event of a battery failure, the
electric parking brake no longer works.
As a safety measure, if the parking
brake is not applied, immobilise the
vehicle by engaging a gear (with a
manual gearbox) or placing a chock at
one of the wheels.
Contact a CITROËN dealer or a
qualified workshop.
Indicator lamp
This indicator lamp comes on in the
instrument panel and in the control
lever to confirm the application of the
parking brake.
The system provides, in automatic operation,
the application of the parking brake on
switching off the engine and release as the
vehicle moves off.
The driver can take over at any time to apply
or release the parking brake, by operating the
control lever:
-

b

y briefly pulling the control lever to apply
the brake,
-

b

y briefly pushing the control lever, while
pressing the foot brake, to release.
Automatic mode is activated by default.
The technology adopted for the electric
parking brake does not allow the fitment
of 15 inch wheels. It goes off to confirm the release of the parking
brake.
The indicator lamp in the control lever flashes
during manual application or release.
After the parking brake has been applied, the
simultaneous flashing of the two indicator
lamps in the instrument panel and the control
lever alerts you to the need to fully secure your
vehicle by engaging a gear (with a manual
gearbox) or by placing the gear selector
in position P with an automatic gearbox,
or by fitting a chock to one of the wheels.
(E.g.

parking on a very steep slope or on a
slope with a low battery).
