Advanced Grip Control
Special patented traction control system which 
improves traction on snow, mud and sand.
This system, the operation of which has been 
optimised for each situation, allows you to 
manoeuvre in most conditions of poor grip 
(encountered during touring use).
Associated with all-season M+S (Mud and 
Snow) tyres, this system offers a  compromise 
between safety, adhesion and traction.
The accelerator pedal should be pressed 
sufficiently to allow the system to use the power 
of the engine. Operation at high engine speeds 
is completely normal.
A five-position selector knob allows you to 
choose the setting best suited to the driving 
conditions encountered.
An indicator lamp associated with each mode 
comes on, accompanied by the display of 
a
  message to confirm your choice.
Operating modes
Standard (ESC)
This mode is calibrated for a low 
l evel of wheel spin, based on the 
different levels of grip normally 
encountered on the road.
Every time the ignition is switched off, the 
system automatically resets to this mode.
Snow
This mode adapts its strategy to 
the conditions of grip encountered 
for each of the two front wheels on 
moving off.
(mode active up to 50
  mph 
(80
 
km/h))
All terrain (mud, damp grass, 
etc.)
This mode, when moving off, allows 
considerable spin on the wheel with 
the least grip to optimise clearing of 
the mud and to regain grip. At the 
same time, the wheel with the most 
grip is controlled in such a   way 
as to transmit as much torque as 
possible.
When moving, the system optimises wheel spin 
to respond to the driver's requirements as fully 
as possible.
(mode active up to 31
  mph (50   km/h))
Sand
This mode allows little spin on the 
two driving wheels at the same time 
to allow the vehicle to move for ward 
and limit the risks of getting stuck in 
the sand.
(mode active up to 75   mph 
(120
 
km/h))
Do not use the other modes on sand as 
the vehicle may become stuck.

You can deactivate the ASR 
and DSC systems by turning 
the knob to the "OFF" position.
Recommendations
Your vehicle is designed principally to 
drive on tarmac roads but it allows you to 
occasionally drive on other less passable 
terrain.
However, it does not permit off-road 
driving such as:
-
 
c
rossing and driving on terrain which 
could damage the underbody or strip 
away components (fuel pipe, fuel 
cooler, etc.) due to obstacles or stones 
in particular,
-
 
d
riving on terrain with steep gradients 
and poor grip,
-
 
c
rossing a   stream.Hill Assist Descent 
Control
System that provides assistance when 
descending on loose or soft sur faces (gravel, 
mud, etc.) or a   steep gradient.
This system reduces the risk of slip or loss 
of control of the vehicle when descending, 
whether going forward or in reverse.
During a
  descent, it assists the driver in 
maintaining a
 
constant speed, depending 
on the gear engaged, while progressively 
releasing the brakes.
For the system to activate, the slope must 
be greater than 5%.
The system can be used with the gearbox 
in neutral.
Otherwise engage a
 
gear corresponding 
to the speed to prevent the engine stalling.
With an automatic gearbox, the system 
can be used with the selector at N , D or R.
When the system is regulating, the Active 
Safety Brake system is automatically 
deactivated. The system is not available:
-
 
i
 f the speed of the vehicle is above 
43   mph (70   km/h),
-  i f the speed of the vehicle is being 
controlled by the Adaptive Cruise 
Control, depending on the type of 
gearbox.
Operation
Switching on
By default, the system is not selected.
The state of the function is not saved when the 
ignition is switched off.
The driver can select the system when 
the engine is running, when the vehicle is 
stationary or when moving at speeds up to 
approximately 31
  mph (50   km/h).
The ASR and DSC systems will no longer 
act on the engine operation or the brakes 
in the event of an involuntary change of 
trajectory.
These systems are reactivated 
automatically from 31
 
mph (50
 
km/h) or 
every time the ignition is switched on.

Advice
The driver must ensure that passengers 
use the seat belts correctly and that they 
are all fastened before setting off.
Wherever you are seated in the vehicle, 
always fasten your seat belt, even for 
short journeys.
Do not interchange the seat belt buckles, 
as they will not fulfil their role fully.
The seat belts are equipped with an 
inertia reel which allows the strap length 
to automatically adjust to your shape. 
The seat belt returns to its storage 
automatically when it is not used.
The inertia reels are fitted with a  device 
which automatically locks the strap in the 
event of a
  collision, emergency braking or 
if the vehicle rolls over. You can release 
the device by pulling the strap firmly and 
then releasing it so that it reels in slightly.
Before and after use, ensure that the seat 
belt is reeled in correctly.
After folding or moving a
  seat or rear 
bench seat, ensure that the seat belt is 
positioned and reeled in correctly. Installation
The lower part of the strap must be 
positioned as low as possible on the 
pelvis.
The upper part must be positioned in the 
hollow of the shoulder.
In order to be effective, a seat belt must:
-
 
b
 e tightened as close to the body as 
possible,
-
 
b
 e pulled in front of you with a   smooth 
movement, checking that it does not 
twist,
-
 
b
 e used to restrain only one person,
-
 
n
 ot show any signs of cuts or fraying,
-
 
n
 ot be converted or modified in order 
not to affect its per formance.
Recommendations for children
Use a
  child seat appropriate to the child's 
age, weight and size.
Never use the same seat belt to secure 
more than one child.
Never allow a
  child to travel on your lap.
For more information on Child seats , refer 
to the corresponding section. Servicing
In accordance with current safety 
regulations, for all repairs on your 
vehicle's seat belts, go to a
  qualified 
workshop with the skills and equipment 
needed, which a
  CITROËN dealer is able 
to provide.
Have your seat belts checked regularly 
by a
  CITROËN dealer or a   qualified 
workshop, particularly if the straps show 
signs of damage.
Clean the seat belt straps with soapy 
water or a
  textile cleaning product, sold by 
CITROËN dealers.
In the event of an impact
Depending on the nature and seriousness 
of the impacts, the pyrotechnic device 
may trigger before and independently of 
airbag deployment. Deployment of the 
pretensioners is accompanied by a
  slight 
discharge of harmless smoke and a
  noise, 
due to the activation of the pyrotechnic 
cartridge incorporated in the system.
In all cases, the airbag warning lamp 
comes on.
Following an impact, have the seat belt 
system checked, and, if necessary, 
replaced, by a
  CITROËN dealer or 
a
 
qualified workshop.

F
 
M
 onitor your environment and keep your 
hands on the wheel to be able to react to 
anything that may happen any time.
F
 
D
 rive smoothly, anticipate the need for 
braking and maintain a
  longer safety 
distance, especially in bad weather.
F
 
S
 top the vehicle to carry out operations 
that require close attention (such as 
adjustments).
F
 
D
 uring long trips, take a   break every two 
hours.
Important!
Never leave the engine running in 
a   closed space without sufficient 
ventilation.  Internal combustion engines 
emit toxic exhaust gases such as carbon 
monoxide. Danger of poisoning and death! In severe wintry conditions (temperature 
below -23°C), let the engine run for 
4
  minutes before moving off, to ensure 
the correct operation and durability of the 
mechanical components of your vehicle 
(engine and gearbox).
Never drive with the parking brake 
applied . Risk of overheating and damage 
to the braking system!
Never park the vehicle or leave the 
engine running on a   flammable sur face 
(dr y grass, dead leaves, etc.). The 
exhaust system of your vehicle is very 
hot, even several minutes after the engine 
stops. Risk of fire!
Never leave a
  vehicle unattended 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). Never leave children inside the vehicle 
unsupervised
.
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.
If you are obliged to drive on a
  flooded road:
F
 
c
 heck that the depth of water does not 
exceed 15
  cm, taking account of waves that 
might be generated by other users,
F
 
d
 eactivate the Stop & Start function,
F
 
d
 rive as slowly as possible without stalling. 
In all cases, do not exceed 6
  mph (10   km/h),
F
 
d
 o not stop and do not switch off the engine.

In case of towing
Driving with a trailer places greater 
d emands on the towing vehicle and 
requires extra care from the driver.
Respect the maximum towable weights.
At altitude:  reduce the maximum load 
by 10% per 1,000
  metres of altitude; the 
decreased air density at altitude reduces 
engine performance. 
New vehicle:  do not pull a
  trailer 
before having driven at least 620
  miles 
(1,000
 
kilometres). If the outside temperature is high, let the 
engine idle for 1
  to 2   minutes after the 
vehicle comes to a   stop, to help it to cool.
Before setting off
Nose weight
On leaving the flooded road, as soon as safety 
conditions allow, make several light brake 
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle, 
contact a
  CITROËN dealer or a   qualified 
workshop.
F
 
D
 istribute the load in the trailer so that the 
heaviest items are as close as possible to 
the axle and the nose weight (at the point 
where it joins your vehicle) approaches the 
maximum permitted without exceeding it.
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 signalling on the trailer and the headlamp beam height of your 
vehicle.
If a
  genuine CITROËN towing device is 
used, the rear parking sensors will be 
deactivated automatically to avoid the 
audible signal.
When driving
Cooling
Towing a trailer uphill increases the 
t emperature of the coolant. The maximum 
towable load depends on the gradient and the 
exterior temperature. The cooling capacity of 
the fan does not increase with engine speed.
F
 
R
 educe speed and lower the engine speed, 
so as to limit the heating-up.
In all cases, pay attention to the coolant 
temperature.
If this warning lamp and the STOP  
warning lamp come on, stop the 
vehicle and switch off the engine as 
soon as possible.
Brakes
Braking distances are increased when towing 
a   trailer. To avoid overheating of the brakes, the 
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the 
wind that the vehicle will have.
