Anti-theft protection
Electronic immobiliser
The keys include an electronic engine
immobiliser system, whose secret code must
be recognised in order for starting to be
possible.
If the system malfunctions, indicated by the
display of a message, the engine will not start.
Contact the CITROËN dealer.
Starting/Switching off the
engine with the key
Key ignition switch
Avoid attaching heavy objects to the key
or the remote control, which would weigh
down on its blade in the ignition switch
and could cause a


malfunction.
Ignition on position
It allows the use of the vehicle's electric
equipment or portable devices to be charged.
Once the state of charge of the battery drops
to the reser ve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preser ve the remaining
battery charge.
Switching off the engine leads to a
loss of
braking assistance.
Starting the engine
F Insert the key into the ignition switch; the system recognises the code.
F

U
nlock the steering column by
simultaneously turning the steering wheel
and the key.
In certain cases, you may have to apply
significant force to move the steering
wheel (wheels on full lock, for example).
It has 3

positions:
-

position 1 (Stop): inserting and removing
the key, steering column locked.
-

position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-

position 3 (Starting) . Parking brake applied:

selector in mode N or P then depress the
brake pedal fully. F

W
ith a petrol engine , operate the starter
motor by turning the key to position
3
without pressing the accelerator pedal,
until the engine starts. Once the engine
starts, release the key.
With petrol engines, after a cold start,
preheating the catalytic converter can
cause noticeable engine vibrations for
anything up to 2 minutes while stationary
with the engine running (accelerated idle
speed).
F

W
ith a Diesel engine , turn the key to
position 2 , ignition on, to operate the engine
pre-heating system.

121
Switching the ignition on
without starting
With the electronic key inside the vehicle,
pressing the "START/STOP " button, without
pressing any of the pedals , allows the
ignition to be switched on without starting the
engine (turning on the instrument panel and
accessories such as the audio system and the
lighting).
F

P
ress this button again to switch off the
ignition and allow the vehicle to be locked.
Key not detected
Back-up starting
A back-up reader is fitted to the steering
column to allow the engine to be started if
the system does not detect the key in the
recognition zone, or when the battery in the
electronic key is discharged. F

W
ith a manual gearbox
, place the gear
lever in neutral, then fully depress the clutch
pedal.
F
W
ith an automatic gearbox
, select mode
P , then fully depress the brake pedal.
F
P
ress the "
START/STOP " button.
The engine starts.
Back-up switch-off
When the electronic key is not detected or is
no longer in the recognition zone, a message
appears in the instrument panel when closing
a
door or trying to switch off the engine.
F

T
o confirm the instruction to switch off the
engine, press the " START/STOP" button for
about five seconds.
Emergency switch-off
In the event of an emergency only, the engine
can be switched off without conditions (even
when driving).
Press the " START/STOP " button for about
5


seconds.
In this case, the steering column locks as soon
as the vehicle stops.
On certain versions with the EAT8
automatic
gearbox, the steering column does not lock.
F

P

lace and hold the remote control against
the reader. In the event of a
fault with the electronic key,
contact a CITROËN dealer or a qualified
workshop.
Electric parking brake
In automatic mode, this system applies the
parking brake when the engine is switched off
and releases it when the vehicle moves off.

122
Indicator lamp
This indicator lamp comes on in the
instrument panel and on the control
lever to confirm the application of
the parking brake, accompanied by
display of the message "Parking
brake applied".
It goes off to confirm the release of the parking
brake.
This indicator lamp flashes on the control lever
when manual parking brake application or
release is performed. In the event of a
battery failure, the
electric parking brake no longer works.
As a safety measure with a manual
gearbox, if the parking brake is not
applied, immobilise the vehicle by
engaging a

gear.
As a safety measure with an automatic
gearbox, if the parking brake is not
applied, immobilise the vehicle by placing
the chocks supplied against one of the
wheels.
Contact a CITROËN dealer or a qualified
workshop.
Before leaving the vehicle, check that the
parking brake is applied: the indicator
lamps in the instrument panel and the
control lever must be on fixed.
If the parking brake is not applied, there
is an audible signal and a
message is
displayed on opening the driver's door. Never leave a
child alone inside the
vehicle as they could release the parking
brake.
Any time that the engine is running, the driver
can take over to apply or release the parking
brake by operating the control lever:
F

b

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

b

y briefly pushing
the control lever, while
pressing the brake pedal, to release it.
Automatic mode is activated by default. When towing, parking on a steep slope
or if your vehicle is heavily laden, turn
the wheels towards the kerb and with
a

manual gearbox, engage a

gear.
When towing, parking on a steep slope,
or if your vehicle is heavily laden, turn the
wheels towards the kerb and select mode
P with an automatic gearbox.
For towing, your vehicle is approved for
parking on slopes of up to 12%.
Manual operation
Manual release
With the ignition on or engine running:
F p ress the brake pedal,
F

w
hile maintaining pressure on the brake
pedal, briefly push the control lever.
The complete release of the parking brake is
confirmed by the brake indicator lamp and the
P indicator lamp in the control lever going off,
accompanied by the display of the message
"Parking brake released".

127
With the engine running and the brakes
released, if R, D or M is selected, the
vehicle moves off, even without pressing
the accelerator pedal.
Never press the accelerator and brake
pedals at the same time – risk of damage
to the gearbox!
In the event of a
battery failure, you
must place the chocks supplied with the
vehicle tools against one of the wheels to
immobilise the vehicle.

After this time limit, the gearbox engages mode
P ; it is then necessary to restart the procedure. If you open the driver's door while mode N
is engaged, an audible signal will sound. It
will stop when you close the driver's door
again.
Special aspects of automatic
mode
The gearbox selects the gear that offers
optimum per formance, taking account of the
exterior temperature, the profile of the road, the
load on the vehicle and the style of driving.
For maximum acceleration without touching the
selector, push the accelerator to the floor (kick-
down). The gearbox shifts down automatically
or holds the gear selected until the maximum
engine speed is reached.
The steering mounted controls allow the driver
to temporarily select a
gear, if the road and
engine speed permit.
Special aspects of manual mode
The change from one gear to another takes
place only if the road speed and engine speed
permit.

The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if this fault occurs.The Stop & Start system requires a
12 V
battery of specific technology and
specification.
All work concerning the battery must be
carried out only by a
CITROËN dealer or
a


qualified workshop.
After the engine has restarted, STOP
mode is not available until the vehicle has
reached a speed of 5 mph (8 km/h).

Load reduction mode
System which manages the use of certain
functions according to the level of charge
remaining in the battery.
When the vehicle is being driven, the load
reduction function temporarily deactivates
certain functions, such as air conditioning,
heated rear screen, etc.
The deactivated functions are reactivated
automatically as soon as conditions permit.
Snow chains
In wintry conditions, snow chains
improve traction as well as the
behaviour of the vehicle when
braking.
Snow chains must be fitted only to the
front wheels. They must never be fitted to
"space-saver" type spare wheels.
Take account of the legislation in force in
