pre-heating fixed.
When the ignition is switched on
with a key in the ignition switch or a
starting instruction made using the
"START/STOP " button, the engine
temperature makes engine pre-
heating necessary. The period of illumination of the indicator lamp is
determined by the ambient conditions (up to about
thirty seconds in severe winter conditions).
With an ignition switch and key, wait until the indicator
lamp goes off before starting.
With Keyless Entry and Starting, once it goes off,
starting is immediate, on condition that the brake
pedal remains pressed with an automatic gearbox, or
the clutch pedal is pressed fully down with a manual
gearbox.
If the engine does not start, switch the ignition off and
then on, wait until the indicator lamp goes off again,
then start the engine.

With the engine running, the front seats can be
heated separately.
Heated seats control
Do not use the function if the seat is not
occupied.
Reduce the level of heating as soon as
possible.
Once the seat and passenger
compartment are at a comfortable
temperature, you can switch off the
function; reducing electric current
consumption also reduces fuel
consumption.Prolonged use at the highest setting
is not recommended for those with
sensitive skin.
There is a risk of burns for those that
do not have normal perception of heat
(illness, taking medicines,
...).
There is a risk of overheating the
system if material with insulating
properties is used, such as cushions or
seat covers.
Do not use the system:
-

i
f wearing damp clothing,
-

i
f child seats are fitted.
To avoid breaking the heating element
in the seat:
-

d
o not place heavy objects on the
seat,
-

d
o not kneel or stand on the seat,
-

d
o not place sharp objects on the
seat,

Recommendations for ventilation and air conditioning
If after an extended stop in sunshine,
the interior temperature is very
high, first ventilate the passenger
compartment for a few moments.
Put the air flow control at a setting high
enough to quickly change the air in the
passenger compartment.
In order for these systems to be fully effective, follow the operation and maintenance
guidelines below:
F

T

o obtain an even air distribution, take care not to obstruct the exterior air intake grilles
located at the base of the windscreen, the nozzles, the vents and the air outlets, as well
as the air extractor located in the boot.
F

D

o not cover the sunshine sensor, located on the dashboard; this is used for regulation
of the air conditioning system.
F

O

perate the air conditioning system for at least 5 to 10 minutes, once or twice a month
to keep it in per fect working order.
F

E

nsure that the passenger compartment filter is in good condition and have the filter
elements replaced regularly.
W

e recommend the use of a combined passenger compartment filter. Thanks to its
special active additive, it contributes to the purification of the air breathed by the
occupants and the cleanliness of the passenger compartment (reduction of allergic
symptoms, bad odours and greasy deposits).
F

T

o ensure correct operation of the air conditioning system, you are also advised to have
it checked regularly as recommended in the maintenance and warranty guide.
F

I

f the system does not produce cold air, switch it off and contact a CITROËN dealer or
a qualified workshop.
When towing the maximum load on a steep gradient in high temperatures, switching off the
air conditioning increases the available engine power and so improves the towing ability. The condensation created by the air
conditioning results in a discharge
of water under the vehicle which is
per fectly normal.
Stop & Start
The heating and air conditioning systems only work when the engine is running.
To maintain a comfortable temperature in the passenger compartment, you can temporarily
deactivate the Stop & Start system.
For more information on Stop & Star t
, refer to the corresponding section.

A setting around the value 21 provides
optimum comfort. However, depending on your
requirements, a setting between 18 and 24 is
normal.
You are advised to avoid a left / right setting
difference of more than 3.
Manual operation
If you wish, you can make a different choice
from that offered by the system by changing
a setting. The the "AUTO" indicator lamps go
off; the other functions will still be controlled
automatically.
With Stop & Start, when demisting has
been activated, the STOP mode is not
available.
The driver and front passenger can each adjust
the temperature to their requirements.
The value indicated on the display corresponds
to a level of comfort and not to a temperature in
degrees Celsius or Fahrenheit.

Driving recommendations
Observe the driving regulations and remain vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your hands on the wheel so that you are ready to react at
any time to any eventuality.
As a safety precaution, the driver must only carry out actions requiring sustained attention when
the vehicle is stationary.
On a long journey, a break every two hours is strongly recommended.
In difficult weather, drive smoothly, anticipate the need to brake and increase the distance from
other vehicles.Never drive with the parking brake
applied - Risk of overheating and
damage to the braking system!
Risk of fire!
As the exhaust system of your vehicle
is very hot, even several minutes
after switching off the engine, do not
park or leave the engine running over
areas where inflammable substances
and materials are present: grass,
leaves,
etc.
Never leave a vehicle unsupervised
with the engine running. If you have
to leave your vehicle with the engine
running, apply the parking brake
and put the gearbox into neutral or
position


N or P, depending on the type
of gearbox.
Driving on flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage
to the engine or gearbox, as well as to the
electrical systems of your vehicle.
Important!
- check that the depth of water does not exceed 15 cm, taking account of waves
that might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without
stalling. In all cases, do not exceed 6 mph
(10
km/h),
-

d
o not stop and do not switch off the
engine.
If you are obliged to drive through water:
On leaving the flooded road, as soon as
circumstances allow, make several light brake
applications to dry the brake discs and pads.
If in doubt on the state of your vehicle, contact
a CITROËN dealer or a qualified workshop.

When towing
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 exterior
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, 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 and the headlamp beam
height of your vehicle.
For more information on Adjusting the
headlamp beam height , refer to the
corresponding section.
For more information on Weights
, refer
to the corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a genuine CITROËN
towbar is used.
If the exterior temperature is high, it
is recommended that the engine be
allowed to idle for 1 to 2 minutes after
the vehicle comes to a stop, to facilitate
its cooling.

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.
It could adversely affect the
deployment of the front airbag.
Starting / Switching off the engine with the key
It has 3 positions:
- position 1 (Stop): insert and removing the
key, steering column locked,
-
position 2 (Ignition on) : steering column
unlocked, ignition on, Diesel preheating,
engine running,
-
position 3 (Starting) .
Ignition switch
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 reserve level, the system switches to
energy economy mode: the power supply is
cut off automatically to preserve the remaining
battery charge.
Switching off the engine leads to a loss
of braking assistance.
Anti-theft protection
Electronic engine immobiliser
In the event of a fault, you are
informed by illumination of this
warning lamp, an audible signal
and/or the display of a message,
depending on version.
Keep safely, away from your vehicle,
the label attached to the keys given to
you on acquisition of the vehicle.
In this case, your vehicle will not start; contact
a CITROËN dealer as soon as possible. The keys contain an electronic chip which has
a special code. When the ignition is switched
on, this code must be recognised for engine
starting to be authorised.
This electronic engine immobiliser locks the
engine management system a few minutes
after the ignition is switched off and prevents
starting of the engine by anyone who does not
have the key.

In wintry conditions, the warning lamp
can stay on for a longer period. When
the engine is hot, the warning lamp
does not come on.
In certain cases, you may have to apply
more force to the steering (wheels on
full lock, for example). If the engine does not start straight
away, switch off the ignition. Wait a
few moments before operating the
starter motor again. If the engine does
not start after several attempts, do not
keep trying: you risk damaging the
starter motor or the engine. Contact
a CITROËN dealer or a qualified
workshop.In temperate conditions, do not leave
the engine at idle to warm up but move
off straight away and drive at moderate
speed.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion
engines emit toxic exhaust gases,
such as carbon monoxide. Danger of
intoxication and death!
In very severe wintry conditions
(temperatures below -23°C), to ensure
the correct operation and durability of
the mechanical components of your
vehicle, engine and gearbox, it is
necessary to leave the engine running
for 4 minutes before moving off.
