Deactivation / Reactivation
In exceptional conditions (starting a vehicle stuck
in mud, immobilised in snow, on soft ground, etc.),
it may be useful to deactivate the ASR system to
freely spin the wheels and regain traction.
Reactivate the system as soon as the level of grip
permits.
It is set via the Driving / Vehicle touch
screen menu.
Deactivation is confirmed by the
illumination of this indicator lamp in the
instrument panel and the display of a message.
The ASR system is reactivated automatically
every time the ignition is switched back on or
from 31 mph (50 km/h).
Reactivation is manual below 31 mph (50 km/h).
Malfunction
In the event of a system malfunction, this
warning lamp comes on, accompanied by
an onscreen message and audible signal.
Contact a dealer or a qualified workshop to have
the systems checked.
ASR / DSC
These systems enhance safety during
normal driving, but should not encourage the
driver to take extra risks or drive at high speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
For technical reasons, in particular to
improve the quality of telematic services
for customers, the Manufacturer reserves the
right to carry out updates to the vehicle's
on-board telematic system at any time.
If you benefit from the DS CONNECT BOX
offer with the SOS and Assistance Pack
included, you have available additional
services in your personal space, via the
website in your country.
For information about the SOS and Assistance
Pack, please refer to the general conditions for
these services.
Electronic stability control
(ESC)
The electronic stability control programme
includes the following systems:
–

An
ti-lock braking system (ABS) and Electronic
brake force distribution (EBFD).
–

Emergenc
y braking assistance (EBA).
–

An
ti-slip regulation (ASR).
–

Dynamic st
ability control (DSC).
Anti-lock braking system (ABS)
and Electronic brake force
distribution (EBFD)
These systems enhance the vehicle’s stability
and handling during braking, and enable greater
control while cornering, particularly on poor or
slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
This warning lamp comes on fixed in the
event of an ABS malfunction.
The vehicle retains conventional braking. Drive
carefully at a moderate speed.
Contact a dealer or a qualified workshop as soon
as possible.
This warning lamp, when lit together with
the STOP and ABS warning lamps,
accompanied by a message and an audible signal,
indicates an EBFD malfunction.
You must stop as soon as it is safe to do so.
Contact a dealer or a qualified workshop.
The normal operation of the ABS may
result in slight vibrations in the brake
pedal.
When braking in an emergency, press very
firmly and maintain this pressure.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
After an impact, have these systems
checked by a dealer or a qualified
workshop.
Emergency braking assistance
(EBA)
In an emergency, this system enables you to reach
the optimum braking pressure more quickly and
therefore reduce the stopping distance.
It is triggered in relation to the speed at which the
brake pedal is pressed. This is felt by a reduction
in the resistance of the pedal and an increase in
braking efficiency.
Anti-slip regulation (ASR) /
Dynamic stability control (DSC)
Anti-slip regulation optimises traction using
engine braking and by applying the brakes on the
driving wheels to avoid wheel spinning. It also
enhances the vehicle's directional stability while
accelerating.
If there is a difference between the vehicle’s
trajectory and the path desired by the driver, the
dynamic stability control system automatically
uses engine braking and the brakes on one or
more wheels to return the vehicle to the desired
path, within the limits of the laws of physics.
These systems are activated automatically every
time the vehicle is started.
They come into operation in the event of a grip or
trajectory problem.
This warning lamp on the instrument panel
flashes to indicate that they are operating.

It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
Correct operation of these systems depends
on compliance with the manufacturer's
recommendations relating to the wheels (tyres
and rims), braking and electronic components,
as well as the assembly and repair procedures
used by dealers.
The use of snow tyres is recommended, to
ensure that these systems remain effective
in winter conditions. All four wheels must be
fitted with tyres approved for the vehicle.
Advanced Traction Control
This special patented traction control system
improves grip on snow, mud and sand.
For optimum grip on snow, it is
recommended to fit the vehicle with
winter tyres.
Activation/Deactivation



►  Press the DRIVE MODE button to choose one of
the three driving modes; the different modes are
displayed in the instrument panel.
►  Depending on the circumstances, select
"Snow", "Mud" or "Sand".
The chosen mode continues to be displayed in the
instrument panel.
►  To deactivate, select "Normal" mode or any
other driving mode.
The system is automatically deactivated when
the ignition is switched off.
Operating modes
Snow
This mode adapts its strategy to the conditions of
grip encountered for each of the two front wheels
on moving off.
(mode active up to 50 mph (80 km/h))
Mud
This mode, when moving off, allows considerable
spin on the wheel with the least grip to optimise
clearing of the mud and to regain grip. At the
same time, the wheel with the most grip is
controlled in such a way as to transmit as much
torque as possible.
When moving, the system optimises wheel spin
to respond to the driver's requirements as fully as
possible.
(mode active up to 31 mph (50 km/h))

Practical information07
Oil filter
Change the oil filter each time the engine
oil is changed.
Particle filter (Diesel)
When the particle filter is approaching
saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp
goes off.
Following prolonged operation of the
vehicle at very low speed or at idle, you
may, in exceptional circumstances, notice the
emission of water vapour at the exhaust while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change).
Electric parking brake
This system does not require any routine
servicing. However, in case of an issue, do
not hesitate to have the system checked by a
dealer or a qualified workshop.
For more information on the Electric
parking brake, refer to the corresponding
section.
Brake pads
Brake wear depends on the style of driving,
particularly in the case of vehicles used in
town, over short distances. It may be necessary to
have the condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a drop in the
brake fluid level indicates that the brake pads are
worn.
After washing the vehicle, moisture, or in
wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a dealer or a qualified
workshop.
Wheels and tyres
The inflation pressure of all tyres,
including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure label
are valid for "cold" tyres. If you have driven for
more than 10 minutes or more than 6 miles (10
kilometres) at over 31 mph (50 km/h), add 0.3 bar
(30 kPa) to the values indicated on the label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
