Trailer Stability Assist (Tsa) - CITROEN C5 AIRCROSS Handbook

Safety
ASR/DSC
These systems offer increased safety
in normal driving, but they 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.
The correct operation of these
systems depends on observation of
the manufacturer's recommendations
regarding both the wheels (tyres and
rims), braking and electronic components
and the assembly and repair procedures
used by CITROËN dealers.
The use of snow tyres is recommended,
in order to be able to benefit from the
efficiency of these systems in winter
conditions.
In this case, it is essential to equip the
four wheels with tyres approved for your
vehicle.

Trailer stability assist (TSA)

When towing, this system reduces the risk of
the vehicle or trailer swaying.
Operation
The system is activated automatically when the
ignition is switched on.
The electronic stability control (ESC) must not
have any faults.
If the system detects oscillations (snaking) in
the movement of the trailer at speeds between
37 and 99 mph (60 and 160 km/h), it acts
on the brakes to stabilise the trailer and, if
necessary, reduces the engine power to slow
down the vehicle.
The correction is signalled by the
flashing of this warning lamp in the
instrument panel and illumination of
the brake lamps.
For information on the weights and towed
loads, refer to the "Technical data" section or
the registration certificate for your vehicle.
To ensure complete safety while driving with
a Towbar device, refer to the corresponding
section.
Operating fault
Should a fault occur with the system,
this warning lamp comes on in the
instrument panel, accompanied by
the display of a message and an
audible signal.
If you continue to tow a trailer, reduce your
speed and drive carefully!
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The trailer stability assist system offers
increased 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 drive at too high a speed.
In certain cases, snaking of the trailer
may not be detected by the ESC system,
particularly with a light trailer.
When driving on slippery or poor surfaces,
the system may not be able to prevent
sudden snaking of the trailer.
