Operating fault
In some cases, such as the maintaining of a
comfortable temperature in the passenger
compartment, it may be useful to deactivate the
Stop & Start.
Deactivation can be requested at any time once
the ignition has been switched on.
If the engine is in STOP mode, it restarts
straight away.
The Stop & Start is reactivated automatically
each time the ignition is switched on.
Deactivation / Reactivation
In the event of a fault in STOP mode, the
vehicle may stall. All of the instrument panel
warning lamps come on.
Depending on version, an alert message may
also be displayed asking you to put the gear
lever into position N and put your foot on the
brake pedal.
It is then necessary to switch off the ignition,
then restart the engine.
The Stop & Start requires a 12
V
battery with special technology and
specifications. All work on this type of
battery must be carried out exclusively
by a CITROËN dealer or a qualified
workshop.
For more information on the 12 V
battery , refer to the corresponding
section. In the event of a malfunction with
the system, the "ECO OFF" switch
warning lamp flashes, then comes on
continuously.

Deactivation is confirmed by the illumination of
the indicator lamp in the control switch and the
display of a message. Driving on flooded roads
Before driving through a flooded road,
it is strongly recommended that you
deactivate the Stop & Start system.

System which automatically maintains the cruising speed of the vehicle at a setting programmed by the driver, without any action on the accelerator
pedal. The cruise control is switched on
manually.
It requires a minimum vehicle speed of
25 mph (40 km/h) as well as:
-

w
ith a manual gearbox, the
engagement of fourth gear or
higher,
-

w
ith an automatic gearbox, the
gear selector at position D or
second gear or higher in manual
mode.
As a safety measure, you are advised
to keep your feet near the pedals at all
times.
Switching off the ignition cancels any
programmed speed setting.
The cruise control system is a driving aid
that cannot, in any circumstances, replace
the need to observe speed limits, nor the
need for vigilance on the part of the driver.
The operation of the cruise control can be
interrupted (pause):
-

b
y pressing control 4 or by pressing the
brake or clutch pedal,
-

a
utomatically, if operation of the dynamic
stability control system is triggered.

You may have to brake to control the speed of
your vehicle. In this case, the cruise control is
automatically paused.
To activate the system again, press button 4.Only use the cruise control if the traffic
conditions will allow you to drive for a
certain time at a steady speed and at a
safe distance from the vehicle ahead.
Do not activate the cruise control
in urban areas, in heavy traffic, on
winding or steep roads, on slippery
or flooded roads, or in conditions of
poor visibility (heavy rain, fog, falling
snow...).
In some circumstances, it may not
be possible to maintain or reach the
programmed speed: towing, vehicle
heavily loaded, steep climb.
Temporarily exceeding the
programmed speed
When required (overtaking manoeuvre...), it is
possible to exceed the programmed speed by
pressing the accelerator pedal.
To return to the programmed speed, simply
release the accelerator pedal.
Once the vehicle has returned to the
programmed speed, the cruise control takes
over again: the display of the programmed
speed setting becomes steady again.
When descending a steep hill, the
cruise control system cannot prevent
the vehicle from exceeding the
programmed speed.
Switching off
F Turn wheel 1 to the "0" position: the cruise
control information disappears from the
screen.
Operating fault
Flashing dashes indicate a fault with the cruise
control system.
Have it checked by a CITROËN dealer or a
qualified workshop. The use of mats not approved by
CITROËN may inter fere with the
operation of the cruise control.
To avoid any risk of jamming of the
pedals:
-
e nsure that the mat is positioned
c o r r e c t l y,
-

n
ever fit one mat on top of another.
The cruise control is temporarily overridden
and the programmed speed setting flashes.

Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels. For more information on snow chains, contact a
CITROËN dealer or a qualified workshop.
Advice on installation
F If you have to fit the chains during a
journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of
your
vehicle.
F

F
it the chains following the instructions
provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
Avoid driving with snow chains on
roads that have been cleared of snow,
to avoid damaging your vehicle's tyres
and the road sur face. If your vehicle
is fitted with alloy wheels, check that
no part of the chain or its fixings is in
contact with the wheel rim.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running
speed authorised.
Use only the chains designed to be fitted to the
type of wheel fitted to your vehicle:
Original
tyre size Maximum

link size.
215/60 R16 9 mm
215/55 R17
225/45 R18
225/40 R19
cannot be fitted with chains
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

For more information on Checking
the levels and in particular on the
diesel additive level, refer to the
corresponding section.
On a new vehicle, the first operations
of regeneration of the particle filter
may be accompanied by the smell of
"burning", which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Refer to the manufacturer's service
schedule for the checking interval for
this component.
Brake disc wear
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
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.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.

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.
Parking brake
If excessive travel or a loss of
effectiveness of this system is
noticed, the parking brake must be
checked, even between two services.
For more information on the Electric parking
brake , refer to the corresponding section.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
