Renault Clio: Electronic stability program (ESC) with understeer control and traction control

Renault Clio IV (2014-2019) Owners Manual / Driving / Driver correction devices and aids / Electronic stability program (ESC) with understeer control and traction control

Electronic stability control ESC

This system helps you to keep control of the vehicle in critical driving conditions (avoiding an obstacle, loss of grip on a bend, etc.).

Operating principle

A sensor in the steering wheel detects the direction selected by the driver.

Other sensors throughout the vehicle measure the actual direction.

The system compares driver input to the actual trajectory of the vehicle and corrects the trajectory if necessary by controlling the braking of certain wheels and/or engine power. In the event that the system is engaged, indicator light flashes on the instrument panel.

Understeer control

This system optimises the action of the ESC in the case of pronounced understeer (loss of front axle road holding).

Traction control

This system helps to limit wheelspin of the drive wheels and to control the vehicle when pulling away accelerating or decelerating.

Operating principle

Using the wheel sensors, the system measures and compares the speed of the drive wheels at all times and slows down their over-rotation. If a wheel is starting to slip, the system brakes automatically until the drive supplied becomes compatible with the level of grip under the wheel again.

The system also adjusts the engine speed to the grip available under the wheels, independently of the pressure exerted on the accelerator pedal.

Operating faults

When the system detects an operating fault the message “CHECK ESC” and warning light and
appear
on the instrument panel. In this case, the ESC and traction control system are deactivated.

Consult an approved dealer.

Disabling the traction control system

In some situations (driving on very wet ground: snow, mud, etc. or driving with snow chains fitted), the system may reduce the engine output to limit wheelspin.
