The C4 On-board comfort also means
enjoyable, relaxed driving in all circumstances. For this reason,
in addition to its wide range of new-generation engines, the C4
boasts a range of technological innovations designed to enhance
driving comfort and so promote better vehicle control. With its
advanced equipment and features, the C4 also offers high level
active and passive safety, along with exceptionally polished road
manners. New technologies have been applied systematically in all
these areas, in order to develop new services and functions that
provide the driver with more information, while letting him
concentrate on the road. The C4 driver has access to a range of
modern and innovative driving aids which, combined with the
interior comfort and uncluttered design of the cabin, let him take
to the road with a relaxed mind.
The lane departure warning system
The lane departure warning system detects a lane change on a
motorway or fast road from speeds of 80 kph. It warns the driver
if the car crosses a continuous or dotted lane marking, if the
indicator is not activated. A vibrating mechanism mounted in the
car seat is activated on the side corresponding to the direction
of vehicle drift, enabling the driver who may have suffered a
moments distraction to take corrective action in time. |

Xenon dual-function directional
headlamps
The C4 is also available with a feature that remains rare in this
segment: Xenon dual-function directional headlamps (low beam and
high beam).
When the car takes a corner, the beam lights up the inside of the
curve, illuminating areas that were previously in darkness.
Front and rear parking assistance
The system lets the driver view the distance separating the car
from the obstacles at both front and rear. The multifunction
screen displays the silhouette of the vehicle, along with six
detection areas.
Cruise control and the speed limiter
Cruise control and the speed limiter round out the list of new
comfort and safety equipment.
Cruise control lets the driver keep the car going at a programmed
speed without using the accelerator pedal.
With the speed limiter, the driver defines a maximum speed not to
be exceeded, whatever the position of his foot on the accelerator.
If he wishes to exceed this speed from time to time, he stamps
down on the pedal in order to pass the hard spot marking the
end-of-travel point of the accelerator.
The low tyre-pressure warning system
This system measures the pressure of all four tyres. When one of
the tyres drops below its preset pressure level, a message
immediately flashes up on the multifunction screen to warn the
driver. In the event of a puncture, the Stop indicator will also
come on. In this way, this feature detects any under-inflation
that could have an adverse impact on the cars stability and on
the safety of the occupants.
To keep the car under control at all times, the C4 driver can rely
on efficient running gear, along with high-performance braking
functions for advanced safety.
High-performance brakes
The C4s braking system features ventilated discs at the front and
discs at the rear, combined with EBS and electronic brake force
distribution (EBD).
To further improve braking safety, the C4 is fitted as standard
with emergency braking assistance (EBA) and automatic hazard
warning lights.
ESP (electronic stability programme) is also available with all
engines. It is coupled with traction control to prevent skidding.
The C4 offers the following passive safety features:
a shape-optimised driver airbag for improved driver protection;
driver and passenger dual-stage front airbags.
curtain airbags standard at front and rear;
driver and passenger chest airbags standard at front;
seatbelts with three anchor points, a force limiter and a
warning light for all seats.
Isofix anchor points at the rear side seats.
Improved cabin protection in the event of frontal impact
The C4 features an additional impact absorbing system on the
lower part of the front end to dissipate energy more effectively
in the event of frontal impact.
This absorbing system is made up of a lower front bumper beam,
along with subframe extensions.
The mechanical resistance of the front suspension and the lower
subframe has been optimised to enable, for example, energy to be
transmitted under the body in the event of frontal impact.
Studies were conducted on the movement of hard incompressible
parts in the engine compartment in order to limit intrusions into
the cabin.
The front doors have been reinforced in order to better stiffen
the whole.
