PRINCIPLES OF OPERATION
Anti-Lock Brake System
ABS cont rol s t he s peed of all road wheel s t o ensure opti mum wheel s li p when braking at the adhesi on li mit . The wheelsare prevent ed from locki ng to ret ai n effecti ve st eeri ng cont rol of the vehicle.
The front brake pres s ures are modul ated s eparat el y for each wheel. The rear brake press ures are modulat ed by s elect low.Select low appli es the same pres sure t o both rear brakes, wi th the press ure level bei ng det ermined by t he wheel on thelower fri ct ion s urface. This maint ai ns rear s tabil it y on s pli t fricti on s urfaces .
Corner Brake Control
CBC i nfluences the brake pres sures , below and wit hin ABS thres holds , to counteract the yawing moment produced whenbraking i n a corner. CBC produces a correcti on t orque by li mi ti ng the brake pres sure on one s ide of t he vehicle.
Dynamic Stability Control
DSC us es brakes and powert rain torque control to as s is t i n maint aining the l ateral st abi lit y of t he vehi cl e. W hil e t heignit ion is energi zed t he DSC funct ion i s permanentl y enabl ed, unl es s s elect ed off us ing t he DSC s wit ch. Even i f DSC isdesel ect ed, driving maneuvers wi th ext reme yaw or lat eral accelerat ion may trigger RSC acti vi ty to as s is t t he vehi cl es tabil it y.
DSC enhances dri ving s afet y in abrupt maneuvers and in under-st eer or over-s teer s ituat ions t hat may occur in a bend. TheABS module monit ors t he yaw rat e and l ateral accel erati on of the vehicle, s t eering input , and then s elect ively appli esindivi dual brakes and s ignals for powertrain t orque adjus t ments t o reduce under-s teer or over-s teer.
In general:
In an under-s t eer s i tuati on; the i nner wheels are braked t o count eract the yaw movement t owards t he outer edgeof the bend.In an over-st eer si tuat ion; the out er wheel s are braked to prevent t he rear end of the vehicl e from pus hing t owardst he out er edge of t he bend.
The ABS module monit ors t he tracki ng s tabil it y of the vehicle usi ng inputs from t he wheel s peed s ens ors, t he s teeringangl e s ensor, and the yaw rat e and lat eral accelerat ion sens or. The t racki ng s tabil it y is compared wit h s t ored t arget dat a.W henever t he t racki ng s tabil it y devi ates from t he target dat a, t he ABS modul e int ervenes by appl yi ng the appropriat ebrakes.

Terrain responsePRINCIPLE OF OPERATION
The Terrain Response System provides an
opportunity for the driver to feed back terrain
information to the vehicle by choosing a
general setting or on e of three special
programs. It then uses that information to
optimise the vehicle's systems for improved
traction and driveability. It does this by
bringing together vehicle drive control systems
which usually opera te individually.
The drive systems optimised by the Terrain
Response Syst em are :-
• Engine management.
• Gearbox management.
• Intelligent coupling control.
• Dynamic stability, trac tion and Hill Descent
controls.
The system will provide a variable accelerator
pedal response, ranging fr om very cautious for
slippery conditions (w here a large pedal
movement has only a small effect on engine
power) to very respon sive (where engine
power is allowed to rise more quickly).
Note: Changing from one special program to
another will introduce noticeably different
responses. For example, the engine revs
produced by the current accelerator pedal
position, may increase or decrease in the new
program.
To familiarise y ourself and get the best from
the system you should try out the programs in
circumstances which are safe for you and other
road users.
Terrain response has been designed to benefit
the driver no matter what their level of off-road
driving experience. The system will aid those
with less experience, a nd enhance the skills of
those with more experience.
USING TERRAIN RESPONSE
Note: The Terrain Response System is
designed to be engaged before crossing
difficult terrain. Do not wait until control has
been lost before usi ng the special programs.
When the vehicle is started, the Terrain
Response System will be in its General
program. The General program will allow the
vehicle to operate capa bly in most conditions,
as some of the sub-systems will react to the
conditions where appropriate. When
conditions change, and more difficult
conditions are encountered, the appropriate
special program should be selected.
Before driving off-road
Before venturing off-road it is absolutely
essential that inexperi enced drivers become
fully familiar with the vehicle's controls. In
particular, CommandShift , Hill Descent Control
(HDC), and the Terra in Response system.
Basic information and off-road driving
techniques can be found in the off-road driving
handbook available on-line at
http://www.ownerinfo.landrover.com
Off-road driver traini ng should be undertaken
by anyone intending to drive off-road. Training
is available at your nearest Land Rover
Experience centre. More details can be found at
http://www.landroverexperience.com
Driver override options
All systems will be se t to their optimum
parameters for the condi tions reflected in the
choice of special program. However, if
required, Hill Descent c ontrol can be operated
independently. See USING HDC (page 137). If
it has not been automatically selected by the
special program, it may be engaged as
required. Converse ly, if it has been selected,
but is not required, it may be turned off.

133
Terrain response
R
The HDC status will be displayed on the
message centre whether it is engaged or
disengaged by the system, or the driver. Use of
HDC in special programs may prompt
additional driving advice , and warnings to be
displayed on the message centre.
Although Dynamic Stab ility Control is
automatically engaged when a special program
is selected, it can be tu rned off if required See
USING TRACTION CONTROL (page 139).
Automatic gear selection can be overridden by
using the CommandS hift function.
Terrain Response operation
A rotary control just in fr ont of the gear lever is
used to select the required special program.
When the selector reaches the end of the
selection range in either direction it can be
rotated further, but it has no effect.
In addition to the general program, there are
three special programs.
• Grass/Gravel/Snow (also used for ice).
• Mud/Ruts.
• Sand. When the starter button is pressed, the
indicators around the rotary control are
illuminated. The active program is highlighted
in amber, and the program icon is displayed in
the message centre.
The special programs remain active for six
hours after the ignition is turned off. If the
ignition is turned on again within six hours the
program will remain ac tive. After six hours the
general program is automatically selected.
General program This program is co mpatible with all
on and off-road conditions. If not
already active, it should be selected
before driving on surfaces which are similar to
a hard road surface. Dry cobbles, tarmac, dry
wooden planks, etc. all fa ll into this category.
