Roadholding and braking are the fundamentals that underpin active safety and accident avoidance. In an emergency, technology can come to the aid of the driver as automatic systems are triggered to correct human error.

A car that brakes quickly when necessary is a safe car. Renault uses four leading-edge electronic systems to improve the capacity and power of braking on its vehicles:

- The emergency braking assistance detects emergency conditions from the speed with which the driver hits the brake, boosting the braking power (which is controlled by ABS) to reach maximum pressure almost immediately.

- ABS (anti-lock braking system) prevents the wheels from locking, even during emergency braking, so that the driver can maintain control of the vehicle's trajectory. EBD, an additional function installed within ABS, permanently adjusts force proportioning between the front and rear wheels.

- ASR traction control prevents the drive wheels from spinning when starting from rest or accelerating in low-grip conditions, particularly on wet roads.

- ESP (Electronic stability programme) helps the driver to maintain the path of the vehicle on bends or during an emergency manoeuvre. A special new function optimizes ESP in emergency situations or when extreme understeer occurs (when the front wheels lose their grip and the vehicle heads for the outside of the bend).
