CHASSIS CONTROL
(where fitted)
The ESP system is not a substitute for winter
tyres or snow chains on a snow covered road.
NOTE
The chassis control is an electric control module
that includes the following functions:
•
The ESP system cannot be switched off when the
ESP system is operating and the “SLIP” indicator
light (

Disabling the ESP system causes the Intelligent
Emergency Braking (IEB) system (where fitted) to
become unavailable. The IEB warning light (

stuck in snow.
The Active Trace Control senses driving based on
the driver’s steering and acceleration/braking pat-
terns, and controls brake pressure at corners and
help smooth vehicle response.

When driving with snow chains.
If the ESP system has been switched off, drive
carefully with reduced speed. When road con-

ELECTRONIC STABILITY
PROGRAMME (ESP) DEACTIVATION
The vehicle should be driven with the Electronic Sta-
bility Programme (ESP) system ON for most driving
conditions.
When the Electronic Stability Programme (ESP) sys-
tem is turned OFF, the Active Trace Control is also
turned OFF.
If the vehicle is stuck in mud or snow, the ESP sys-
tem reduces the engine output to decrease wheel
spin. The engine speed will be reduced even if the
accelerator is depressed to the floor. If maximum
engine power is needed to free a stuck vehicle, turn
the ESP system off.
To turn off the ESP system, Use the Vehicle Informa-
tion Display, see “Vehicle information display” in the
“2. Instruments and controls” section for operational
details. The ESP OFF indicator light (
on.
