Driving
6Towing
Driving with a trailer places greater
demands on the towing vehicle and
particular care must be taken.
Do not exceed the maximum towable
weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the lower
air density at high altitudes decreases engine
performance.
New vehicle: do not tow a trailer until the
vehicle has 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 the amount of heating produced.
►


Pay constant 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
Using the engine brake is recommended to limit
the overheating of the brakes. Braking distances
are increased when towing a trailer.
Side wind
Bear in mind that the vehicle will be more
susceptible to wind when towing.
Anti-theft protection
Electronic immobiliser
The keys contain a code, which must be
recognised by the vehicle before starting is
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,
never leave the electronic key in the
vehicle, even when you are close to it.

Driving
6coming out of reverse gear or turning the
steering wheel.
Restarting the engine (START mode)
The engine automatically restarts as soon as the
driver indicates the intention of moving off again:
With a manual gearbox: with the clutch pedal
fully depressed.
With an automatic gearbox:
–
With the selector in mode
D or M: with the
brake pedal released.
–

With the selector in mode
N and the brake
pedal released: with the selector at D or M.
–

With the selector in mode
P and the brake
pedal depressed: with the selector at R, N, D
or M.
–

With reverse gear engaged.
Special cases
The engine will restart automatically if the
conditions for operation are met again and in the
following cases:
–
V
ehicle speed exceeds 2 mph (3 km/h).
–

Some specific conditions (braking assistance,
air conditioning setting, etc.).
In these cases, this indicator lamp flashes
for a few seconds, then goes off.
Malfunctions
In the event of a malfunction, the button’s
indicator lamp flashes briefly, then remains on.
Have it checked by a CITROËN dealer or a
qualified workshop.
The vehicle stalls in STOP mode
All of the instrument panel warning lamps come
on if there is a fault.
►

Switch off the ignition then start the engine
again with the key or the " ST

ART/STOP" button.
12 V battery
The Stop & Start system requires a
12 V battery of specific technology and
specification.
All work must be carried out only by a
CITROËN dealer or a qualified workshop
Tyre under-inflation detection
This system alerts the driver if one or more tyres
suffer a drop in pressure.
The alert is raised when the vehicle is moving,
not when stationary.
It compares the information given by the wheel
speed sensors with reference values, which
must be reinitialised every time the tyre
pressures are adjusted or a wheel changed.
It takes into account the last values stored
during the reinitialisation request. It is therefore
essential that the tyre pressure is correct during
the operation. This operation is the driver’s
responsibility.
The tyre under-inflation detection cannot, in any circumstances, replace the need
for vigilance on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel), especially before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
–

worsens road-holding.
–


lengthens braking distances.
–


causes premature wear of the tyres.
–


increases energy consumption.
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
For more information on the Identification
markings, refer to the corresponding section.
Checking tyre pressures
This check should be done monthly
when the tyres are "cold" (vehicle stopped for
1 hour or after a journey of less than 6 miles
(10

km) at moderate speeds).
Otherwise, add 0.3 bar to the pressures
shown on the label.

209
Event data recorders
Event data recorders
Electronic control units are installed in your
vehicle. Control units process data which is
received by vehicle sensors, for example, or
which they generate themselves or exchange
amongst themselves. Some control units are
necessary for the safe functioning of your
vehicle, others assist you while you drive (driver
assistance systems), while others provide
comfort or infotainment functions.
The following contains general information about
data processing in the vehicle. You will find
additional information as to which specific data is
uploaded, stored and passed on to third parties
and for what purpose in your vehicle under
the key word Data Protection closely linked
to the references for the affected functional
characteristics in the relevant owner's manual
or in the general terms of sale. These are also
available online.
Operating data in the
vehicle
Control units process data for operation of the
vehicle.
This data includes, for example:
–
vehicle status information (e.g. speed,
movement delay

, lateral acceleration, wheel
rotation rate, "seat belts fastened" display)
–

ambient conditions (e.g. temperature, rain
sensor

, distance sensor) As a rule such data is transient and is not stored
for longer than an operational cycle, and only
processed on board the vehicle itself. Often
control units include data storage (including the
vehicle key). This is used to allow information
to be documented temporarily or permanently
on vehicle condition, component stress,
maintenance requirements and technical events
and errors.
Depending on technical equipment levels, the
data stored is as follows:
–

system component operating states (e.g. fill
level, tyre pressure, battery status)
–

faults and defects in important system
components (e.g. lights, brakes)
–

system reactions in special driving situations
(e.g. triggering of an airbag, actuation of the
stability control systems)
–

information on events damaging the vehicle
–

for electric vehicles the amount of charge in
the high-voltage battery
, estimated range
In special cases (e.g. if the vehicle has detected
a malfunction), it may be necessary to save data
that would otherwise just be volatile.
When you use services (e.g. repairs,
maintenance), the operating data saved can
be read together with the vehicle identification
number and used where necessary. Staff
working for the service network (e.g. garages,
manufacturers) or third parties (e.g. breakdown
services) can read the data from the vehicle.
The same applies to warranty work and quality
assurance measures. Data is generally read via the OBD (On-Board
Diagnostics) port prescribed by law in the
vehicle. The operating data read documents the
technical condition of the vehicle or individual
components and assists with fault diagnosis,
compliance with warranty obligations and quality
improvement. This data, in particular information
on component stress, technical events, operator
errors and other faults, is transmitted to the
manufacturer where appropriate, together
with the vehicle identification number. The
manufacturer is also subject to product liability.
The manufacturer potentially also uses operating
data from vehicles for product recalls. This data
can also be used to check customer warranty
and guarantee claims.
Fault memories in the vehicle can be reset by a
service company when carrying out servicing or
repairs or at your request.
Comfort and infotainment
functions
Comfort settings and custom settings can be
stored in the vehicle and changed or reset at any
time.
Depending on the equipment level in question,
these include
–

seat and steering wheel position settings
–


chassis and air conditioning settings
–


custom settings such as interior lighting
Y

ou can input your own data in the infotainment
functions for your vehicle as part of the selected
features.
