pressure on the pedal until the
engine starts. If the electronic key is not detected
in the zone, a message is displayed.
Move the electronic key into the zone
so that the engine can be started.
If one of the starting conditions is not
met, a reminder message appears in
the instrument panel screen. In some
circumstances, it is necessary to
turn the steering wheel slightly while
pressing the " START/STOP " button
to assist unlocking of the steering;
a message warns you when this is
needed.
The presence of the "Keyless Entry
and Starting" electronic key in the
recognition zone is essential.
As a safety measure, do not leave this
zone with the vehicle running.
diesel vehicles
In temperatures below zero
the engine will not start until
the preheater warning lamp
has gone off.
If this warning lamp comes on after
pressing " START/STOP ", you should
hold the brake or clutch pedal down
until the warning lamp goes off and do
not press the " START/STOP" button
again.
The steering column unlocks and the engine
starts more or less instantly.
See the advice below for Diesel versions.
It is not necessary to place the electronic key in
the reader.

Invalid value during manual
operation
This symbol is displayed if a gear
is not engaged correctly (selector
between two positions).
Stopping the vehicle
Before switching off the engine, you can
engage position P or N to place the gearbox in
neutral.
In both cases, apply the parking brake to
immobilise the vehicle, unless it is programmed
to automatic mode.If the lever is not in position P , when the
driver's door is opened or approximately
45 seconds after the ignition is switched
off, there is an audible signal and a
message appears.
F

R
eturn the lever to position P ;
the audible signal stops and the
message disappears.
Operating fault
When the ignition is on, the lighting of this
warning lamp, accompanied by an audible
signal and a message in the multifunction
screen, indicates a gearbox malfunction.
In this case, the gearbox switches to back-up
mode and is locked in 3rd gear. You may feel
a substantial knock when changing from P
to R and from N to R . This will not cause any
damage to the gearbox.
Do not exceed 60 mph (100 km/h), local speed
restrictions permitting.
Have it checked by a CITROËN dealer or a
qualified workshop.
This warning lamp may also come on if a door
is opened. You risk damaging the gearbox:
-

i
f you press the accelerator and
brake pedals at the same time,
-

i
f you force the lever from position
P

to another position when the
battery is flat.
To reduce fuel consumption when
stationary for long periods with the
engine running (traffic jam...), position
the gear lever at N and apply the
parking brake, unless it is programmed
in automatic mode.
driving

Stop & StartThe Stop & Start system puts the engine temporarily into standby - STOP mode - during stops in the traffic (red lights, traffic jams, or other...).
T he engine restarts automatically - START mode - as soon as you want to move off. The restart takes place instantly, quickly and silently.
Per fect for urban use, the Stop & Start system reduces fuel consumption and exhaust emissions as well as the noise level when stationary.
Operation
Going into engine STOP mode
With an electronic gearbox, for your
comfort during parking manoeuvres,
STOP mode is not available for a
few
seconds after coming out of
reverse gear.
STOP mode does not affect the
functionality of the vehicle, such as
braking, power steering, for example.
Never refuel with the engine in STOP
mode; you must switch off the ignition
with the key or the "START/STOP"
button.
The
"ECO" warning lamp comes on
in the instrument panel and the engine
goes into standby automatically:
-

w

ith a manual gearbox
, at speeds below
12 mph (20 km/h), or vehicle stationary with
PureTech 130 petrol and BlueHDi 115 and
120 Diesel versions, when you put the gear
lever into neutral and release the clutch
pedal,
-

w

ith an electronic gearbox , at a speed
below 5 mph (8 km/h), when you press
the brake pedal or place the gear lever in
position N .
-

w

ith an automatic gearbox, vehicle
stationary, when you press the brake pedal
or place the gear lever in position N .If your vehicle is fitted with the
system, a time counter calculates
the sum of the periods in STOP
mode during a journey. It resets
itself to zero every time the
ignition is switched on with the
key or the "START/STOP" button.
STOP mode is not invoked when:
-
t
he vehicle is on a steep slope (up or
d ow n),
-
t
he driver's door is open,
-
t
he driver's seat belt is not fastened,
- t he vehicle has not exceeded 6 mph
(10 km/h) since the last engine start (using
the key or the "START/STOP" button),
-

t
he electric parking brake is applied or
being applied,
-

t
he engine is needed to maintain a
comfortable temperature in the passenger
compartment,
-

d
emisting is active,
-

s
ome special conditions (battery charge,
engine temperature, braking assistance,
ambient temperature...) where the engine is
needed to assure control of a system.
Special cases: STOP mode
unavailable
In this case, the "ECO" warning lamp
flashes for a few seconds, then goes
of f.
This operation is perfectly normal.

Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer or a
qualified workshop.Only use products recommended by
CITROËN or products of equivalent
quality and specification.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake
must be checked, even between
two
services.
Brake pads
Brake wear depends on the style
of driving, particularly in the case
of vehicles used in town, over short
distances. It may be necessary to have
the condition of the brakes checked,
even between vehicle services.
For more information, refer to the "Electric
parking brake - Operating faults" section.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.

driving advice
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.
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 ambient
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 on a long
mountain type of descent, 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.
Refer to the "Technical data" section for
details of the weights and towed loads
which apply to your vehicle.
The rear parking sensors will be
deactivated automatically if a genuine
CITROËN towbar is used.

The GTW and towed load values indicated are valid up to a maximum altitude of 1 000 metres; the towed load mentioned must be reduced by 10 % for
each additional 1 000 metres of altitude.
When towing, the maximum authorised speed is reduced (comply with the legislation in force in your country).
High ambient temperatures may result in a reduction in the per formance of the vehicle to protect the engine; if the ambient temperature is above 37 °C,
limit the towed load.
