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.

Engine oil level: general information
It is normal for an engine to use oil for
lubrication and cooling of moving parts
and it is normal to top up the level between
oil changes.
However, contact your approved
Dealer if more than 0.5 litres is being
consumed every 600 miles (1,000 km)
after the running in period.
