Lesson 2 – ChassisRide and Handling Optimization 

The Terrain Response rotary control is located in the
center console and allows the selection of five operating
programs. Each program is denoted by a symbol which
represents the terrain encountered. The rotary control
can be rotated to select the required program. The
control will only select the last program in its direction
of rotation. Further rotation of the control once the last
program in either direction has been selected, will have
no effect, e.g. once rock crawl has been selected, further...

torque output from the transmission. In sand the
transmission will provide an output which passes
maximum engine power from the transmission.
In rock crawl special program (low range) the
transmission will select 1st gear for driving off.
Sport mode is only available when the general program
is selected and the transfer box is in high range. Sport
mode is disabled in low range and all Terrain Response
special programs. CommandShift™ is available in any
program and also in high or low range.

ABS Control
The ABS module controls several vehicle functions and
adjusts the operating parameters of these functions to
optimise the selected Terrain Response program.
Traction control uses different slip/acceleration
thresholds to improve traction and vehicle composure.
For example, the system sensitivity is increased on
slippery surfaces to reduce wheel spin.
If DSC is switched off (with the DSC switch on the
instrument panel) when using a Terrain Response special
program, if the special program is...

Driver Information
The high specification instrument cluster fitted to all
vehicles with Terrain Response, contains a message
center which displays vehicle information to the driver.
The message center contains the Terrain Response
program icons which display the currently selected
program. If no symbol is displayed, no special program
is selected and the system is in special programs off.
Any required changes to the subsystems are also passed
to the driver in the form of indicator illumination in the...

NOTE: The message SYSTEM FAULT SPECIAL
PROGRAMS NOT AVAILABLE can also be generated
by a fault in the Terrain Response rotary control or
control module. See following section for details of
rotary control or control module faults.
It is not possible for the Terrain Response control
module to cause any fault behaviour (warning indicator
illumination or message generation) in any of the five
sub-systems. Illumination of a sub-system warning
indicator and/or a sub-system related message will never
be...
