ABS – ESP
These systems are additional aids when
driving in critical situations, allowing the
behaviour of the vehicle to be adapted
to the driver's wishes.
However these systems intervene
taking the place of the driver.
They cannot extend the vehicle's limits
and should not encourage you to drive
f a s t e r.
They cannot, in any circumstances,
replace the need for vigilance, or
the responsibility of the driver when
manoeuvring the vehicle (the driver
must always be alive to sudden events
that could occur while driving).Precautions
In an emergency, it is recommended that you
apply the brakes firmly and continuously.
It is not necessary to successively apply and
release the brakes (pumping the pedal).
The ABS will modulate the brake effort
applied.
ABS (anti-lock braking
system)
The ABS avoids locking the wheels under
heavy braking, so optimising the stopping
distance and allowing control of the vehicle to
be retained.
In these conditions, avoiding manoeuvres while
braking are possible.
In addition, this system optimises the stopping
distance on sur faces offering poor grip (wet
roads…).
ABS (warning lamp)
It comes on when the vehicle is switched on
and then goes off shortly after wards.
If it comes on when driving, it signals a fault in
the anti-lock braking system.
The braking system then operates as on
a vehicle not fitted with ABS. Contact a

ESP
This system helps retain control of the vehicle
in "critical" driving situations (avoiding an
obstacle, loss of grip in a corner…).
Principle of operation
A steering wheel sensor provides information
on the trajectory wanted by the driver.
Other sensors around the vehicle measure the
actual trajectory.
The system compares the driver's wishes with
the actual trajectory of the vehicle, correcting
the latter if necessary by acting on certain
brakes and/or the engine power.
ESP (warning lamp)
It comes on when the vehicle is switched on
and then goes off shortly after wards.
The ESP warning lamp flashes in regulation
mode, when its is called on to maintain grip.
If it comes on when driving, it signals a fault
in the ESP: contact a CITROËN authorised

Operation of the system can be felt by vibration
in the brake pedal.
The ABS does not improve the "physical"
per formance possible, which depends on the
grip between the tyres and the road.
It follows that the normal safe driving practices
must be observed (distance between
vehicles…).
