Park Assist
This system provides active assistance with parking, detecting a parking space then
c
ontrolling the steering to park in the space.
It
controls the steering while the driver
m
anages the accelerator, brakes, gears and
c
lutch (manual gearbox). During phases of
e
ntry into and exit from a parking space, the
s
ystem provides visual and audible information
t
o the driver in order to make the manoeuvres
s
afe. It may be necessary to move for wards
a
nd backwards more than once. During
a manoeuvre the steering wheel
t
urns quickly: do not hold the steering
w
heel, do not place your hand between
t
he spokes of the steering wheel and
t
ake care with loose and bulky clothing,
s
carves, handbags... There is a risk of
in
jury.
When
Park Assist is activated, it
p
revents a change to STOP mode of
S
top & Start. In STOP mode, activation
o
f Park Assist restarts the engine.
The
Park Assist system cannot in any
c
ircumstances replace the need for
v
igilance on the part of the driver.
The
driver must remain in control
o
f their vehicle ensuring that the
s
pace remains clear throughout the
m
anoeuvre.
In
some circumstances, the sensors
m
ay not detect small obstacles located
i
n their blind spots.
The
driver can take control at any time by
g
ripping the steering wheel. The
Park Assist system provides assistance for t
he following manoeuvres:
-
e
ntry into a parallel parking space
-
e
xit from a parallel parking space
-
b
ay parkingThe
Park Assist system takes control
o
f the power steering for a maximum
o
f 4 manoeuvre cycles. The function
i
s deactivated after these 4 cycles.
I
f you think that your vehicle is not
p
ositioned correctly, you should then
t
ake control of the steering to carry out
t
he manoeuvre.
The
Park Assist system cannot work
w
ith the engine off.

Electronic Stability Control (ESC) incorporating the following systems:
-
a
nti-lock braking system (ABS) and the
e
lectronic brake force distribution (EBFD),
-
e
mergency braking assistance (EBA),
-
w
heel anti-slip regulation (ASR) or traction
c
ontrol,
-
d
ynamic stability control (DSC).
Electronic stability control (ESC)
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and manoeuvrability of your vehicle when braking
a
nd contributes towards improved control in
c
orners, in particular on poor or slippery road
su
rfaces.
The
ABS prevents wheel lock in the event of
em
ergency
b
raking.
The
electronic brake force distribution system
m
anages the braking pressure wheel by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach the optimum braking pressure more
q
uickly and therefore reduce the stopping
di
stance.
It
is triggered according to the speed at which
t
he brake pedal is pressed. This is felt by a
r
eduction in the resistance of the pedal and an
i
ncrease in the effectiveness of the braking.
Anti-slip regulation (ASR)
The ASR system (also known as Traction Control) optimises traction in order to limit
w
heel slip by acting on the brakes of the driving
w
heels and on the engine. It also improves
t
he directional stability of the vehicle on
a
cceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed by the vehicle and that required by
t
he driver, the DSC monitors each wheel and
a
utomatically acts on the brake of one or more
w
heels and on the engine to return the vehicle
t
o the required path, within the limits of the laws
o
f physics.

Dynamic stability control (DSC)
and anti-slip regulation (ASR)Activation
These systems are activated automatically each time the vehicle is started.
As
soon as they detect a problem of grip or
t
rajectory, these systems act on the operation if
t
he engine and brakes.
Deactivation
In exceptional conditions (starting a vehicle which is bogged down, stuck in snow, on soft
g
round...), it may be advisable to deactivate
t
he DSC and ASR, so that the wheels can turn
f
reely and regain grip.
This
is
indicated
by
flashing
of
this
w
arning
lamp
in
the
instrument
panel. Reactivate
the systems as soon as the level of
g
rip permits. F
P
ress this button.
This
indicator lamp and the indicator
l
amp in the button come on.
The
DSC and ASR systems no longer act
o
n the operation of the engine and on the
b
rakes in the event of a involuntary change of
t
rajectory.
DSC/ASR
The DSC and ASR systems offer increased s afety in normal driving, but they should not
e
ncourage the driver to take extra risks or drive
a
t high speed.
It
is in conditions of reduced grip (rain, snow,
i
ce) that the risk of loss of grip increases.
I
t is therefore important for your safety to
k
eep the DSC and ASR systems activated
i
n all conditions, and particularly in difficult
c
onditions. The
correct operation of these systems
d
epends on observation of the manufacturer's
r
ecommendations regarding as much the
w
heels (tyres and rims), braking and electronic
c
omponents as the assembly and repair
p
rocedures used by CITROËN dealers.
To benefit in full from the effectiveness of the
D
SC and ASR systems in wintry conditions,
t
he vehicle must be fitted with four snow
t
yres, allowing the the vehicle to retain neutral
b
ehaviour on the road.

Driving advice
Distribution of loads
F Distribute the load in the trailer so that the h
eaviest items are as close as possible to t
he axle and the nose weight approaches the
m
aximum permitted without exceeding it.
Air
density decreases with altitude, thus
r
educing engine per formance. Above
1 0
00 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.
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. F
I
f the warning lamp and the
S
TOP
warning lamp come on,
s
top the vehicle and switch off
t
he engine as soon as possible.
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.
Ty r e s
F Check the tyre pressures of the towing v
ehicle and of the trailer, observing the
re
commended
p
ressures.
Lighting
F Check the electrical lighting and signalling o
n the trailer.
Refer
to
the
"Technical
data"
section
for
details
o
f
the
weights
and
towed
loads
which
apply
to
y
our
vehicle.
When
not
towing
a
trailer,
remove
the
q
uickly-detachable
tow
ball
before
d
riving. The
rear parking sensors will be
d
eactivated automatically if a genuine
C
ITROËN towbar is used.

Brake wear depends on the style of driving, particularly in the case
o
f vehicles used in town, over short
d
istances. It may be necessary to
h
ave
the
condition of the brakes checked, even
b
etween
v
ehicle
s
ervices.
Unless
there is a leak in the circuit, a drop in
t
he
brake
fluid level indicates that the brake
p
ads
are
worn.
Brake pads
For information on checking brake d isc wear, contact a CITROËN dealer
o
r a qualified workshop.
Brake disc wear
Only use products recommended by CITROËN or products of equivalent
q
uality
an
d
sp
ecification.
In
order to optimise the operation of
u
nits as important as those in the
b
raking system, CITROËN selects and
o
ffers very specific products.
After
washing the vehicle, dampness,
o
r in wintry conditions, ice can form
o
n the brake discs and pads: braking
e
fficiency may be reduced. Make light
b
rake applications to dry and defrost
t
he brakes.
Electric parking brake
For more information, refer to the "Electric parking brake - Operating faults" section.
This
system does not require any
r
outine servicing. However, in the
e
vent of a problem, have the system
c
hecked by a CITROËN dealer or a
q
ualified
w
orkshop.
Manual gearbox
The gearbox does not require any m
aintenance (no oil change).
Refer
to the manufacturer's service

omponent.
Electronic gearbox
The gearbox does not require any maintenance (no oil change).
Refer
to the manufacturer's service
s
chedule for details of the checking
i
nterval for this component.
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
Refer
to the manufacturer's service
s
chedule for details of the level
c
hecking interval for this component.To
avoid damaging the electrical units,
n
ever use a high pressure jet wash in
t
he engine compartment.
