This system improves safety in the front 
seats in the event of a  front or side impact. 
Depending on the severity of the impact, the 
pyrotechnic pretensioning system instantly 
tightens the seat belts against the body of the 
occupants.
The pyrotechnic pretensioning seat belts are 
enabled when the ignition is on.
The force limiter reduces the pressure of the 
seat belt on the chest of the occupant, thus 
improving their protection.
Fastening
F Pull the strap, then insert the tongue in the  buckle.
F
 
C

correctly by pulling the strap.
Unfastening
F Press the red button on the buckle.
F  G uide the seat belt as it is reeled in.
Height adjustment
F To adjust the height of the anchorage point, squeeze control A and slide it to the notch 
desired.
Rear seat belts
Each of the rear seats has a three-point seat 
b elt with inertia reel.
The outer seats are fitted with a
  pyrotechnic 
pretensioning and force limiting system. Before per forming any operations on the 
rear seats, to avoid damage to the seat 
belts, check that:
-
 
t
 he outer seat belts are correctly in the 
storage position, lying vertically along 
the pillar,
-  
t
 he central seat belt is stowed.
Fastening
F Pull the strap then insert the tongue in the 
buckle.

top of the backrest to prevent the tongue 
from knocking against the side trim.
Rear central seat belt
The seat belt for the rear central seat is 
integrated into the roof. 
Safety  
Page 168 of 292
166
Malfunction
The system may suffer temporary 
interference in certain weather conditions 
(rain, hail, etc.).
In particular, driving on a  wet sur face 
or moving from a
  dry area to a   wet area 
can cause false alerts (for example, 
the presence of a
  fog of water droplets 
in the blind spot angle is interpreted as 
a
 
vehicle).
In bad or wintry weather, ensure that the 
sensors are not covered by mud, ice or 
snow.
Take care not to cover the warning zone in 
the door mirrors or the detection zones on 
the front and rear bumpers with adhesive 
labels or other objects; they may hamper 
the correct operation of the system.
The system is automatically deactivated 
when towing with a
  towing device 
approved by CITROËN.
If a
 
fault occurs, this warning lamp comes on 
in the instrument panel, accompanied by the 
display of a
 
message.
Contact a
 
CITROËN dealer or a
 
qualified 
workshop to have the system checked.
No alert will be given and no correction will be 
made in the following situations: -
 i
n the presence of non-moving objects 
(parked vehicles, barriers, street lamps, 
road signs, etc.),
-
 
w
ith vehicles moving in the opposite 
direction,
-
 
d
riving on a
 
winding road or a
 
sharp corner,
-
 
w
hen overtaking or being overtaken by 
a
 
very long vehicle (lorry, bus, etc.) which is 
both in the rear blind spot and present in the 
driver's front field of vision,
-
 
w
hen overtaking quickly,
-
 
i
n very heavy traffic: vehicles detected in 
front and behind are confused with a
 
lorry or 
a
 
stationary object,
-
 
i
f the Park Assist function is activated.

pressure jet wash, the towball must be removed 
and the protective plug fitted to the carrier.

clearly visible 
area, close to the carrier or in the boot.

Bonnet
The location of the interior bonnet release 
lever prevents opening the bonnet when 
the left-hand front door is shut.When the engine is hot, handle the 
exterior safety catch and the bonnet 
stay with care (risk of burns), using the 
protected area.
When the bonnet is open, take care not to 
damage the safety catch.
Do not open the bonnet under very windy 
conditions.
The cooling fan may star t after 
switching off the engine: take care 
with articles and clothing that might be 
caught by the fan blades.
Opening
F Open the left-hand front door.
Before doing anything under the bonnet, 
deactivate the Stop & Start system to 
avoid the risk of injury related to an 
automatic change to START mode. F
 
P
 ull the release lever, located at the bottom 
of the door aperture, towards you.
Version without longitudinal 
bars
The roof bar fixings include a lug to be fitted 
i nto the hole at each fixing point.
Version with longitudinal 
bars
You must fit the transverse bars to the 
longitudinal bars at the engraved markings on 
the longitudinal bars.
To install the roof bars, you must secure them 
only to the four fixing points on the roof frame. 
These points are concealed by the vehicle's 
doors when they are closed.

If the warning lamp stays on, this indicates 
a  low Diesel additive level.
For more information on Checking levels , 
refer to the corresponding section.
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.
New vehicle
The first particle filter regeneration 
operations may be accompanied by a 
"burning" smell, which is per fectly normal.
Manual gearbox
The gearbox does not require any 
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any 
maintenance (no oil change).
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.
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.
Electric parking brake
This system does not require any 
routine servicing. However, in case 
of an issue, do not hesitate to have 
the system checked by a
  CITROËN 
dealer or a
  qualified workshop.
For more information on the Electric 
parking brake , refer to the corresponding 
section.
Wheels and tyres
The pressure must be checked on 
all tyres, including the spare wheel, 
when the tyres are "cold", at least 
once a
  month and before a   long 
j o u r n ey.
The pressures indicated on the tyre pressure 
label are valid for "cold" tyres. If you have 
driven for more than 10
  minutes or more 
than 6
 
miles (10   kilometres) at over 31   mph 
(50
 
km/h), add 0.3   bar (30   kPa) to the values 
indicated on the label.

F  R emove and then store the bottle of sealant.
Take care, the sealant product is harmful 
if swallowed and causes irritation to the 
eyes.
Keep this product out of the reach of 
children.
The use-by date of the fluid is marked on 
the bottle.
After use, do not discard the bottle in 
standard waste, take it to a
  CITROËN 
dealer or an authorised waste disposal 
site.
Do not forget to obtain a
  new bottle of 
sealant, available from a
  CITROËN dealer 
or a
 
qualified workshop.

Do not drive more than 125   miles (200   km) 
with a
  repaired tyre; see a   CITROËN 
dealer or a
  qualified workshop to change 
the tyre.
Should the pressure of one or more tyres 
be adjusted, it is necessary to reinitialise 
the under-inflation detection system.
