Limit the causes of excess consumption
Spread loads throughout the vehicle; place the heaviest items in the bottom of the boot, as close as possible to the rear seats.
Limit
the loads carried in the vehicle and reduce wind resistance (roof
b
ars, roof rack, bicycle carrier, trailer...). Use a roof box in preference.
Remove
roof bars and roof racks after use.
At
the end of winter, remove snow tyres and refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold, referring to the label in the door aperture, driver's side.
Carry
out this check in particular:
-
b
efore a long journey,
-
a
t each change of season,
-
a
fter a long period out of use.
Don't
forget the spare wheel and the tyres on any trailer or caravan.
Have
your vehicle serviced regularly (engine oil, oil filter, air filter,
p
assenger compartment filter...) and observe the schedule of
o
perations recommended in the maintenance and warranty guide.
With
a Blue HDi Diesel engine, if the SCR system is faulty your vehicle
b
ecomes polluting; go to a CITROËN dealer or a qualified workshop
w
ithout delay to have the emissions of nitrous oxides brought back to
t
he legal level.
When
refuelling, do not continue after the third cut-off of the nozzle to
a
void any over flow.
At
the wheel of your new vehicle, it is only after the first 1 800 miles
(3
000 kilometres) that you will see the fuel consumption settle down to
a
consistent average.

Towing a trailer
Towbar suitable for the attachment of a trailer with a dditional l ighting an d s ignalling. We
recommend the use of genuine
C
ITR
oË
N towbars and their harnesses
that have been tested and approved
from the design stage of your vehicle,
a
nd that the fitting of the towbar is
e
ntrusted to a CITR
oË
N dealer or a
qualified
w
orkshop.
If the towbar is not fitted by a CITR
oË
N
dealer, it is imperative that it is
f
itted in accordance with the vehicle
manufacturer's
i
nstructions.
Driving with a trailer places greater demands
o
n the towing vehicle and the driver must take
par
ticular
c
are.
driving advice
distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to t
he axle and the nose weight approaches the
m
aximum permitted without exceeding it.
ai
r density decreases with altitude, thus
reducing
engine per formance. Above
1
000 metres, the maximum towed load must
b
e reduced by 10 % for every 1 000 metres of
al
titude.
Side wind
F Take into account the increased sensitivity t
o side wind.
Your
vehicle
is
primarily
designed
for
t
ransporting
people
and
luggage,
but
it
may
a
lso
be
used
for
towing
a
trailer. Refer to the "Technical Data" section for details
of the weights and towed loads which apply to
y
our vehicle.

RAcING towbar
Your vehicle cannot be fitted with a
towbar. The space occupied by the
s
port diffuser prevents this.
Ty r e s
F Check the tyre pressures of the towing v
ehicle and of the trailer, observing the
re
commended
p
ressures.
cooling
Towing a trailer on a slope increases the temperature of the coolant.
As
the fan is electrically controlled, its cooling
c
apacity is not dependent on the engine speed.
F
T
o lower the engine speed, reduce your
s
peed.
The
maximum towed load on a long incline
d
epends on the gradient and the ambient
t
emperature.
In
all cases, keep a check on the coolant
t
emperature.
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes on a long
m
ountain type of descent, the use of engine
b
raking is recommended.
Lighting
F Check the electrical lighting and signalling o
n the trailer.
The
rear parking sensors will be
d
eactivated automatically if a genuine
C
ITROËN towbar is used.
