Driving
Driving recommendations
► Observe the driving regulations and remain vigilant whatever the traffic conditions.► Monitor your environment and keep your hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that require close attention (such as adjustments).► During 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!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry 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:
► check that the depth of water does not exceed 15 cm, taking account of waves that might be generated by other users,► deactivate the Stop & Start function,► drive as slowly as possible without stalling. In all cases, do not exceed 6 mph (10 km/h),► do not stop and do not switch off the engine.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.
In case of towing
Driving with a trailer places greater
demands 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 density
of the air decreases with altitude and the
performance of the engine reduces.
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
► Distribute 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.
Tyres
► Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
► 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 causes the coolant
temperature to increase. The maximum towable
load depends on the gradient and the exterior
temperature. The fan’s cooling capacity does not
increase with engine speed.
► Reduce speed and lower the engine speed to limit heating up.

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 the brakes, the use
of engine braking is recommended.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
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 a CITROËN dealer.
For safety and theft protection reasons,
do not leave your electronic key in the
vehicle, even when you are close to it.
It is recommended that you keep it with you.
Starting / Switching off the
engine with the key
Key ignition switch

It has 3 positions:– 1. Stop : inserting and removing the key,
steering column locked.
– 2. Ignition : steering column unlocked, ignition
on, Diesel preheating, engine running.
– 3. Starting.
Avoid attaching heavy objects to the key or the remote control. It would weigh
down on its shaft 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 reserve level, the system switches to energy
economy mode : the power supply is cut off

Practical information
– the green mark on the star wheel is in line
with the white mark on the ball joint,
– the locking wheel is in contact with the towball (position A),– the security key lock is on and the key removed; the locking wheel can no longer be
operated,
– the towball must not be able to move in its carrier; test by shaking it with your hand.
If the towball is not locked, the trailer can
detach - accident risk!
During use
Never release the locking system with a
trailer or load carrier on the towball.
Never exceed the maximum authorised
weight for the vehicle - the Gross Train
Weight or GTW.
It is essential that the maximum authorised
load be complied with on the towing device:
if it is exceeded, this device may detach from
the vehicle, which is a serious accident risk.
Check that the trailer lamps work correctly.
Before setting off, check the adjustment of the
headlamp beam height.
For more information on Headlamp
adjustment, refer to the corresponding
section.
Following use
When travelling without a trailer or load
on a towbar-mounted carrier, the towball
must be removed and the protective plug
inserted in the carrier. This measure applies
particularly where the towball might obscure
visibility of the number plate or its lighting.
Fitting the towball

► Below the rear bumper , remove the protective plug 2 from the towball carrier 1.

► Insert the end of towball 5 into carrier 1 and
push it upwards; the locking will take place
automatically.


► The locking wheel 6 turns a quarter of a turn
anti-clockwise ; take care to keep your hands
clear!


► Check that the mechanism has correctly locked into place and that the green mark on the
star wheel is in line with the white mark on the
towball (position A).
► Close the lock 7 using the key.

128
Practical information
► Refit protective plug 2 to carrier 1.► Carefully stow the towball in its bag away from knocks and dirt.
Maintenance
Correct operation is only possible if the towball
and its carrier are kept clean.
Before cleaning the vehicle with a high-pressure
jet wash, the towball must be removed and the
protective plug fitted to the carrier.
Apply the label provided to a clearly visible area, close to the carrier or in the
boot.
Go to a CITROËN dealer or a qualified
workshop for any work on the towbar system.
Towing device
Load distribution► 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 performance. The maximum load which
can be towed must be reduced by 10% per
1,000 metres of altitude.
Use towing devices and their genuine
wiring harnesses approved by CITROËN.
It is recommended that the installation be
performed by a CITROËN dealer or a
qualified workshop.
If not fitted by a CITROËN dealer, it
must still be fitted in accordance with the
manufacturer's instructions.
Certain driving or manoeuvring aid functions
are automatically deactivated if an approved
towing system is used.
Observe the maximum authorised
towable weight, indicated on the vehicle's
registration certificate, the manufacturer's
label as well as in the Technical data section
of this guide.
Complying with the maximum authorised
nose weight (towball) also includes the
use of accessories (bicycle carriers, tow
boxes, etc.).
Observe the legislation in force in the
country where you are driving.
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.
Energy economy mode
This system manages the duration of use of
certain functions, in order to conserve a sufficient
level of charge in the battery with the ignition off.
After switching off the engine, you can still
use functions such as the audio and telematic
system, the wipers and the dipped beam
headlamps or courtesy lamps, for a combined
duration of approximately 40 minutes.
Switching to this mode
A message appears in the instrument panel
screen indicating that the vehicle has switched to
economy mode and the active functions are put
on standby.
If a telephone call is being made at this
time, it will be maintained for around 10
minutes with the Bluetooth hands-free system
of your audio system.
Exiting the mode
These functions are automatically reactivated the
next time the vehicle is used.
To restore the use of these functions
immediately, start the engine and let it run:
– For less than 10 minutes, to use the equipment for approximately 5 minutes.
– For more than 10 minutes, to use the equipment for approximately 30 minutes.
Let the engine run for the specified duration to
ensure that the battery charge is sufficient.
To recharge the battery, avoid repeatedly or
continuously restarting the engine.
A flat battery prevents the engine from
starting.
For more information on the
12 V battery,
refer to the corresponding section.
Roof bars
For safety reasons and to avoid
damaging the roof, it is essential to use
the transverse bars approved for your vehicle.
