Anti-Lock Braking System (Abs) - Renault Sandero Owner's Manual

ANTI-LOCK BRAKING SYSTEM (ABS)

Under heavy braking, the essential re-
quirements are to limit the stopping
distance and keep your vehicle under
control. However, there is a risk that
roadholding and directional control
may be lost and the wheels may lock
under braking, depending on the nature
of the ground, weather conditions and
your reactions. The Anti-lock Braking
System (ABS) has been designed to
combat this danger.
The safety enhancement is that the
brake control system prevents the
wheels from locking, even if the brakes
are applied too sharply, and allows the
vehicle to be steered and thus its direc-
tion to be controlled. Under these cir-
cumstances it is quite possible for the
driver to steer the vehicle and to avoid
an obstacle whilst at the same time
applying the brake. This system also
allows you to optimise stopping dis-
tances, especially when roadholding
becomes difficult (wet or slippery roads,
varying road surfaces).
The braking modulation provided by the ABS is independent of the effort applied
to the brake pedal. In an emergency, apply firm and continuous pressure to the
brake pedal. There is no need to pump it repeatedly.
2.12
Although this system allows you to
make maximum use of stopping dis-
tances, even with the ABS you still have
to take account of the actual condition
of the road surface.
It is still essential to follow the rules
of good driving practice (such as driv-
ing at a safe distance from the vehicle
in front). The fact that the vehicle's
safety has been increased should
not encourage you to take risks.
You will feel a pulsation through the
brake pedal each time the system is ac-
tivated. These tangible signs will warn
you that the adhesion between the
tyres and the ground has reached its
limit and enable you to adapt your driv-
ing style to suit the road conditions.
Operating faults
Two possible situations may occur:
x
1 – Warning light is lit on the
instrument panel.
Braking is still performed, but with-
out the ABS system. Contact an
approved dealer as soon as pos-
sible.
x
2 – The and
warning lights on the in-
strument panel come on.
This indicates that both the brak-
ing system and the ABS system
are faulty. Your braking systems are
only partially operational. However,
it is dangerous to brake suddenly
and it is essential to stop immedi-
ately, as soon as traffic conditions
allow. Contact an approved dealer
as soon as possible.
