•
When driving on extremely inclined surfaces
such as higher banked corners, the ESP sys-
tem may not operate properly and the ESP
warning light may illuminate. Do not drive
on these types of roads.
•
When driving on an unstable surface such as
a turntable, ferry, elevator or ramp, the ESP
warning light may illuminate. This is not a
malfunction. Restart the engine after driving
onto a stable surface.
•
If wheels or tyres other than the RENAULT
recommended ones are used, the ESP sys-
tem may not operate properly and the ESP
warning light may illuminate.
•
The ESP system is not a substitute for winter
tyres or tyre chains on a snow covered road.
The Electronic Stability Programme (ESP) system
uses various sensors to monitor driver inputs and
vehicle motion. Under certain driving conditions, the
ESP system performs the following functions:
•
Controls brake pressure to reduce wheel slip on
one slipping drive wheel so power is transferred
to a non slipping drive wheel on the same axle.
•
Controls brake pressure and engine output to
reduce drive wheel slip based on vehicle speed
(traction control function).

Starting and driving
•
Controls brake pressure at individual wheels and
engine output to help the driver maintain control
of the vehicle in the following conditions:
– understeer (vehicle tends to not follow the
steered path despite increased steering in-
put)
– oversteer (vehicle tends to spin due to cer-
tain road or driving conditions).
The ESP system can help the driver to maintain con-
trol of the vehicle, but it cannot prevent loss of ve-
hicle control in all driving situations.
When the ESP system operates, the ESP warning
light in the instrument panel flashes so note the
following:
•
The road may be slippery or the system may
determine some action is required to help the
vehicle on the steered path.
•
You may feel a pulsation in the brake pedal and
hear a noise or vibration from under the bonnet.
This is normal and indicates that the ESP system
is working properly.
•
Adjust your speed and driving to the road condi-
tions.
If a malfunction occurs in the system, the ESP warn-
ing light illuminates in the instrument panel. The
ESP system automatically turns off.
The ESP OFF switch is used to turn off the ESP
system. The ESP off indicator light
to indicate the ESP system is off. When the ESP
OFF switch is used to turn off the system, the ESP
system still operates to prevent one drive wheel from
slipping by transferring power to a non slipping drive
wheel. The ESP warning light
occurs. All other ESP functions are off and the ESP
warning light will not flash. The ESP system is
automatically reset to on when the ignition switch is
placed in the OFF position then back to the ON posi-
tion.
When the <4LO> position is selected with the Four-
Wheel Drive (4WD) mode switch, the ESP system
is disabled and the ESP OFF indicator light illumi-
nates.
See "Warning lights, indicator lights and audible
reminders" in the "2. Instruments and controls" sec-
tion and "Four-Wheel Drive (4WD) (where fitted)"
earlier in this section.
The computer has a built-in diagnostic feature that
tests the system each time you start the engine and
move the vehicle forward or in reverse at a slow
speed. When the self-test occurs, you may hear a
"clunk" noise and/or feel a pulsation in the brake
pedal. This is normal and is not an indication of a
malfunction.
