- a ring B, behind the seat and identified by
a marking, referred to as the TOP TETHER
for fixing the upper strap.
This ISOFIX mounting system provides fast,
reliable and safe fitting of the child seat in your
vehicle.
The ISOFIX child seats are fitted with two
latches which are secured on the two rings A .
Some seats also have an upper strap , known
as the Top Tether, which is attached to ring B .
To secure the child seat to the TOP TETHER :
-

r
emove and stow the head restraint before
installing the child seat on the seat (refit it
once the child seat has been removed),
-

r
aise the carpet cover to expose the TOP
TETHER,
-

p
ass the upper strap of the child seat behind
the seat backrest, between the apertures
for the head restraint rods, When fitting an ISOFIX child seat to the
left-hand rear seat, before fitting the
seat, first move the centre rear seat belt
towards the middle of the vehicle, so
as to avoid the seat inter fering with the
operation of the seat belt.
The incorrect installation of a child seat in
a vehicle compromises the protection of
the child in the event of an accident.
Strictly obser ve the fitting instructions
provided with the child seat.
For information on the possibilities for
installing ISOFIX child seats in your
vehicle, refer to the summary table.
Also consult the installation notes of the
child seat’s manufacturer to find out how
to install and remove the seat.

In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
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 performance. The maximum
towed load must be reduced by 10% for every
1,000 metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
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.
Side wind
F Take into account the increased sensitivity to 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 this 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 Headlamp
adjustment , refer to the corresponding
section.
The rear parking sensors will be
deactivated automatically to avoid
the audible signal if a genuine DS
AUTOMOBILES towbar is used.

When the vehicle is being driven,
if this warning lamp and the STOP
warning lamp come on, accompanied
by an audible signal and a message
on the multifunction screen, this
indicates that the parking brake is still
on or has not been fully released.
When parking on a slope, direct your
wheels towards the kerb, apply the
parking brake, engage a gear and switch
off the ignition.
Electric parking brake
The electric parking brake combines
2 operating modes:
-

A
utomatic application/release
Application is automatic when the engine stops,
release is automatic on use of the accelerator
(activated by default),
-

M
anual application/release
The parking brake can be applied/released
manually by pulling control lever .
If this warning lamp comes on in
the instrument panel, the automatic
mode is deactivated.
Do not place any object (packet of
cigarettes, telephone...) between the gear
lever and the electric parking brake control
l eve r.
Programming the mode
Depending on the country of sale of the vehicle,
the automatic application when the engine is
switched off and the automatic release when
you press the accelerator can be deactivated.
Activation/deactivation of the system
is done in the vehicle configuration
menu.
The parking brake is locked and unlocked
manually. When the driver’s door is opened, a
loud beep is heard and a message is displayed
if the parking brake has not been applied. It is recommended that you do not apply
the parking brake in very cold conditions
(ice) and during towing (breakdown,
caravan...). Deactivate the automatic
functions and release the parking brake
manually.

Manual application
With the vehicle stationary, to apply the parking
brake regardless of whether the engine is
running or switched off, pull the control lever.
The application of the parking brake is
confirmed by:
When the driver’s door is opened with the
engine running, a message is displayed
accompanied by an audible signal if the parking
brake has not been applied, except in the case

brake will not be released and a
warning lamp will come on in the
instrument panel.
Maximum application
If necessary, you can make maximum
application of the parking brake. It is obtained
by means of a long pull on control lever , until
you see the message "Parking brake applied

Maximum application is essential:
-

i
n the case of a vehicle towing a caravan
or a trailer, if the automatic functions are
activated but you are applying the parking
brake manually,
-

w
hen the gradient you are parked on may
vary (e.g. on a ferry, on a lorry, during
towing). In the case of towing, a loaded vehicle or
parking on a gradient, make a maximum
application of the parking brake then turn
the front wheels towards the kerb and
engage a gear when you park.
After a maximum application, the release
time will be longer.

Use the cruise control only where the
driving conditions allow running at a
constant speed for a while and at an
adequate safe distance.
Do not activate the cruise control in urban
areas, in heavy traffic, on winding or steep
roads, on slippery or flooded roads, or in
conditions of poor visibility (heavy rain,
fog, falling snow etc.).
In some circumstances, it may not
be possible to maintain or reach the
programmed speed: towing, vehicle
heavily loaded, steep climb, etc.
The use of mats not approved by the
manufacturer may interfere with the
operation of the cruise control.
To avoid any risk of jamming of the pedals:
-
e
nsure that the mat is positioned
c o r r e c t l y,
-

n
ever place one mat on top of another.Lane departure warning
system
System which detects the involuntary crossing
of longitudinal traffic lane markings on the
ground (solid or broken line).
Sensors, fitted below the front bumper, trigger
a warning if the vehicle drifts over a lane
marking (speed higher than 50 mph (80 km/h)).
This system is particularly useful on motor ways
and main roads.The lane departure warning system
cannot, in any circumstances replace the
need for vigilance on the part of the driver.
It is necessary to obser ve the driving
regulations and take a break every two
hours.
Activation
F When switching on the ignition or with the engine running, press this button to activate
the system; the indicator lamp comes on.
Deactivation
F Press this button again, the indicator lamp goes off.
The status of the system remains in memory
when the ignition is switched off.
Detection
You are warned by the vibration of the driver's
seat cushion:
-

o
n the right-hand side, if the marking on the
road has been crossed on the right,
-

o
n the left-hand side, if the marking on the
road has been crossed on the left.
No warning is given while the direction indicator
is active and for approximately 20 seconds
after the direction indicator is switched off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
Malfunction
In the event of a malfunction, the
Ser vice warning lamp comes on,
accompanied by an audible signal
and a message in the screen.
Contact the dealer network or a qualified
workshop.
