brake PEUGEOT 4C 2015 Owner's Guide

This guarantees greater braking stability for the vehicle,
preventing sudden locking of the rear wheels and the
consequent instability of the vehicle.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turningthe ignition Off and On again may reset the ABS if the
fault detected was only momentary.
WARNING!
•When the ABS intervenes and you feel the brake
pedal pulsating, do not reduce the pressure, but
hold it down firmly and confidently; in doing so
you will brake in the shortest distance possible,
depending on the current road conditions.
•For maximum efficiency of the braking system, a
bedding-in period of about 311 miles (500 km) is
required: during this period it is advisable to avoid
sharp, repeated and prolonged braking.
•If the ABS intervenes, this indicates that the grip of
the tires on the road is nearing its limit: you must
slow down to a speed compatible with the avail-
able grip.

178 STARTING AND OPERATING

WARNING!(Continued)
•The ABS can’t overrule the natural laws of physics,
and can’t increase the grip available according to
the condition of the road.
•The ABS cannot prevent accidents, including those
due to excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
•The capability of the ABS must never be tested
irresponsibly and dangerously, in such a way as to
compromise personal safety and the safety of oth-
ers.
•For the correct operation of the ABS, the tires must
of necessity be the same make and type on all
wheels, in perfect condition and, above all, of the
prescribed type and dimensions.When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as
the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
System Intervention
A slight pulsing of the brake pedal and noise indicates
the intervention of the ABS: this is completely normal
when the system intervenes.

STARTING AND OPERATING 179

Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing the
distribution of brake pressure on the four wheels: the
system prevents the wheels on the inside of the corner
(less affected by the weight of the car) from locking,
ensuring better stability and direction for the car.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and intervenes
in the event of sudden downshifting, or during braking
when the ABS intervenes, restoring torque to the engine
and thus preventing excessive drag at the drive wheels,
which may lead the wheels to lock and a loss of car
stability, above all in low-grip conditions.
AntiSlip Regulation System (ASR)
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
collisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent col-
lisions.The capabilities of an ESC equipped ve-
hicle must never be exploited in a reckless or
dangerous manner which could jeopardize the us-
er ’s safety or the safety of others.

180 STARTING AND OPERATING

Hill Start Assist (HSA)
This is an integral part of the ESC system and facilitates
starting on slopes, activating automatically in the follow-
ing cases:
•Uphill: car stationary on a road with a gradient higher
than 5%, engine running, brake pressed and transmis-
sion in neutral (N) or gear other than reverse engaged.
•Downhill: car stationary on a road with a gradient
higher than 5%, engine running, brake pressed and
reverse (R) gear engaged.
When setting off, the ESC system control unit maintains
the braking pressure on the wheels until the engine
torque necessary for starting is reached, or in any case for
a maximum of two seconds, allowing your right foot to
be moved easily from the brake pedal to the accelerator.When the two seconds have elapsed, without starting,
the system is automatically deactivated, gradually releas-
ing the braking pressure. During this release stage, the
typical brake disengagement noise, indicating that the
car is going to move imminently, can be heard.
NOTE:
•HSA is not a parking brake; therefore, never leave the
vehicle without having engaged the parking brake,
turned the engine off and engaged first gear, so that
the vehicle is parked in safe conditions.
•There may be situations on small gradients (less than
8%), with vehicle laden, in which the Hill Holder
system may not activate, causing a slight reversing
motion and increasing the risk of collision with an-
other vehicle or object. The driver is, in any case,
responsible for safe driving.
182 STARTING AND OPERATING

Hydraulic Brake Assistant System (HBA)
WARNING!
•The HBA system can’t overrule the natural laws of
physics, and can’t increase the grip available ac-
cording to the condition of the road.
•The HBA system cannot prevent accidents, includ-
ing those due to excessive speed on corners, driv-
ing on low-grip surfaces or aquaplaning.
•The capability of the HBA system must never be
tested irresponsibly and dangerously, in such a
way as to compromise the safety of the driver, the
other occupants of the car or any other road user.
The HBA system is designed to improve the car ’s braking
capacity during emergency braking. The system detects
emergency braking by monitoring the speed and force
with which the brake pedal is pressed, and consequentlyapplies the optimal brake pressure. This can reduce the
braking distance, the HBA system therefore completes
the ABS.
Maximum assistance from the HBA system is obtained
pressing the brake pedal very quickly. In addition, the
brake pedal should be pressed continuously during
braking, avoiding intermittent presses, to get the most
out of the system.
Do not reduce pressure on the brake pedal until braking
is no longer necessary.
The HBA system is deactivated when the brake pedal is
released.

Electronic Q2 System (E-Q2)
TheElectronic Q2system intervenes during accelera-
tion on corners, braking the inner drive wheel and thus
increasing the traction of the outer wheel (which bears
more of the car ’s weight): the torque is thus distributed
optimally between the drive wheels in accordance with
the driving conditions and road surface, permitting par-
ticularly effective, sporty driving.
Ready Alert Brake System (RAB)
This function activates automatically if the accelerator
pedal is released rapidly, reducing the brake pad travel
(both at front and back), with the aim of preparing the
braking system and enhancing its responsiveness, thus
reducing the stopping distance in the event of subse-
quent braking.

the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
