Recalling a stored position
Ignition on or engine running
F Press button 1 or 2 to recall the corresponding position. An audible signal
indicates the completion of the adjustment.
You can interrupt the current movement by
pressing button M , 1 or 2 or by using one
of the seat controls.
A stored position cannot be recalled while
driving.
Recalling stored positions is deactivated
45 seconds after switching off the ignition.
Heated seats control
F Use the adjustment dial, placed on the side of each front seat, to switch on and select
the level of heating required:
0 Of f.
1 Low.
2 Medium.
3 High.
With the engine running, the front seats can be
heated separately. Do not use the function when the seat is
not occupied.
Reduce the intensity of the heating as
soon as possible.
When the seat and passenger
compartment have reached an adequate
temperature, you can stop the function;
reducing the consumption of electrical
current reduces fuel consumption.Prolonged use at the highest setting is
not recommended for those with sensitive
skin.
There is a risk of burns for people whose
perception of heat is impaired (illness,
taking medication, etc.).
There is a risk of overheating the system if
material with insulating properties is used,
such as cushions or seat covers.
Do not use the system:
-

i
f wearing damp clothing,
-

i
f child seats are fitted.
To avoid breaking the heating element in
the seat:
-

d
o not place heavy objects on the seat,
-

d
o not kneel or stand on the seat,
-

d
o not place sharp objects on the seat,
-

d
o not spill liquids onto the seat.
To avoid the risk of short-circuit:
-

d
o not use liquid products for cleaning
the seat,
-
n

ever use the heating function when
the seat is damp.

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a long journey, a break every two hours is
strongly recommended.
In bad weather, drive smoothly, anticipate the
need to brake and increase the distance from
other vehicles.Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4 minutes before driving.
Important!
Never drive with the parking brake applied
– Risk of overheating and damage to the
braking system!
Do not park and do not run the engine,
the vehicle is stationary, in areas where
substances and combustible materials
(dry grass, leaves ...) can come into
contact with the hot exhaust system – Risk
of fire!
Never leave a vehicle unsuper vised 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.
Driving 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 through water:
-

c
heck that the depth of water does not
exceed 6 inches (15 cm), taking account
of waves that might be generated by other
users,
-
d
eactivate the Stop & Start function,
-
d
rive slowly as possible without stalling. In
every case, do not exceed a speed of 6 mph
(10 km/h),
-
d
o not stop and do not turn off the engine.
On leaving the flooded road, and as soon as
safety conditions permit, brake lightly several
times to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact the dealer network 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.
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.

The hard disk or peripheral
is not recognised when
connecting to the USB socket.Some hard disks and devices need a power supply
greater than is provided by the audio system.
Connect the peripheral to the 230 V socket, the 12
V
socket or an external power supply.
Caution : make sure that the device does not output
a voltage greater than 5 V (risk of destruction of the
syste m).
When streaming, the sound
cuts out momentarily. Some telephone models prioritise the connection with
the "hands-free" profile. Delete the "hands-free" connection profile to improve
streaming.
In "Random all" play, not all of
the tracks are played. In "Random all" play, the system can only accept up to
999 tracks.
With the engine off, the audio
system switches off after a few
minutes of use. When the engine is switched off, the audio system
operating time depends on the charge level of the
vehicle's battery.
The switch-off is normal: energy economy mode is
activated automatically to preser ve the battery charge
level required to start the engine. (See the "Energy
Economy Mode" section). Start the vehicle's engine to increase the battery charge.
The message "the audio system
is overheated" appears on the
display. In order to protect the installation if the surrounding
temperature is too high, the audio system switches
to an automatic thermal protection mode leading to a
reduction of the volume or stopping of the playing of the
CD. Switch the audio system off for a few minutes to allow
the system to cool.
