Limit the causes of excess
consumption
Spread loads throughout the vehicle; place
the heaviest items in the bottom of the boot,
as close as possible to the rear seats.
Limit the loads carried in the vehicle and
reduce wind resistance (roof bars, roof rack,
bicycle carrier, trailer...). Preferably, use a roof
box.
Remove roof bars and roof racks after use.
At the end of winter, remove snow tyres and
refit your summer tyres.
Observe the recommendations on
maintenance
Check the tyre pressures regularly, when cold,
referring to the label in the door aperture,
driver's side.
Carry out this check in particular:
-
b
efore a long journey,
-

a
t each change of season,
-

a
fter a long period out of use. Have your vehicle ser viced regularly (engine
oil, oil filter, air filter, cabin filter...) and
obser ve the schedule of operations in the
manufacturer's service schedule.
With a BlueHDi Diesel engine, if the SCR
system is faulty, your vehicle becomes
polluting. As soon as possible, visit a member
of the dealer network or a qualified workshop
to make your vehicle’s level of nitrogen oxides
emissions compliant to the standard.
When filling the tank, do not continue after the
3rd cut-off of the nozzle to avoid over flow.
At the wheel of your new vehicle, it is only
after around the first 1,900 miles (3,000
kilometres) that you will see the fuel
consumption settle down to a consistent
average. Do not forget the spare wheel and the tyres on
any trailer or caravan.
Eco-driving

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.

Rear parking sensors
The system is switched on by engaging reverse
g e a r.
This is confirmed by an audible signal.
The system is switched off when you come out
of reverse gear.
Audible assistanceVisual assistanceThis supplements the audible signal by
displaying bars in the screen which move
progressively nearer to the vehicle.
When the obstacle is very close, the "Danger"
symbol is displayed in the screen.
Front parking sensors
In addition to the rear parking sensors, the
front parking sensors are triggered when an
obstacle is detected in front and the speed of
the vehicle is still below 6 mph (10 km/h).
The front parking sensors are interrupted if
the vehicle stops for more than three seconds
in for ward gear, if no further obstacles are
detected or when the speed of the vehicle
exceeds 6 mph (10 km/h).
The sound emitted by the speaker (front or
rear) indicates whether the obstacle is in
front or behind.
Deactivation/activation of the
front and rear parking sensors
The function is deactivated by pressing this
button. The button indicator lamp comes on.
Pressing this button again reactivates the
function. The button indicator lamp goes off.
The function will be deactivated
automatically if a trailer is being towed or a
bicycle carrier is fitted (vehicle fitted with a
towbar or an approved bicycle carrier).
The proximity information is given by an
intermittent audible signal, the frequency of
which increases as the vehicle approaches the
obstacle.
The sound emitted by the speaker (right or
left) indicates the side on which the obstacle is
located.
When the distance between the vehicle and
the obstacle becomes less than approximately
thirty centimetres, the audible signal becomes
continuous.

To w b a r
Your vehicle is primarily designed for
transporting people and luggage, but it may
also be used for towing a trailer.We recommend the use of genuine
DS AUTOMOBILES towbars and their
harnesses that have been tested and
approved from the design stage of your
vehicle, and that the fitting of the towbar
is entrusted to a dealer or a qualified
workshop.
If the towbar is not fitted by a dealer, it
must still be fitted in accordance with the
vehicle manufacturer's instructions. Driving with a trailer places greater
demands on the towing vehicle and the
driver must take particular care.
For more information on Driving advice
,
particularly when towing, refer to the
corresponding section.
Obser ve the maximum authorised towable
weight, indicated on your 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.).
The maximum authorised nose weight
does not depend on the type of device
installed, fixed or removable, with or
without a tool.
