Safety
05
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.
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 / reactivation is confirmed by 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.
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.
Trailer stability assist (TSA)
When towing, this system reduces the risk of the
vehicle or trailer snaking.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control system (ESC) must
not have any faults.
Between 37 and 99 mph (60 and 160km/h), if
the system detects oscillations (snaking) in the
movement of the trailer, it acts on the brakes to
stabilise the trailer and, if necessary, reduces
engine power to slow down the vehicle.
This warning lamp flashes in the
instrument panel and the brake lamps light
up to draw attention to this corrective action.
For information on towed loads and masses, refer
to the Technical data section or your vehicle’s
registration certificate
To ensure complete safety while driving with a
Towing device, refer to the corresponding section.
Malfunction
If a fault occurs, this warning lamp comes
on in the instrument panel, accompanied
by a message and an audible signal.
If you wish to continue towing a trailer, reduce
your speed and drive carefully!
Contact a dealer or a qualified workshop to have
the system checked.
The trailer stability assist system offers
enhanced safety in normal driving,
provided that the recommendations on towing
a trailer are observed. It should not encourage
the driver to take risks, such as towing a trailer
in adverse operating conditions (overloading,
failure to observe the trailer nose weight, worn
or under-inflated tyres, faulty braking system,
etc.), or to drive at excessive speeds.
In certain cases, the system may not detect
trailer snaking, particularly with a light trailer.
