R
Increasing the cruise speed
Press and hold the + switch to increase speed.
Release the switch when the desired speed is
reached, the new speed will be set and
maintained.
The speed can be increased incrementally by
tapping the + switch. Each press of the switch
will increase the speed by 2 km/h (1 mph).
Speed can also be increased using the
accelerator. When the de sired speed is reached
press the + switch to set and maintain the new
speed.
CAUTION
When setting the cruise control to the
speed limit it is important to remember
that it is possible for the vehicle speed to
increase when travelling downhill. This may
result in the vehicle speed exceeding the speed
limit.

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

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.

This program should be selected once the need
for a special program has passed. Once the
special program has been deselected, all of the
vehicle systems will retu rn to their normal
settings except HDC. HD C will remain active if
it was selected manually.
Grass-Gravel-Snow This program should be used
where a firm surface is covered
with loose, or s lippery material.
Surfaces covered in water, ice, slime, grass,
gravel, shale, pebbles, or a thin coating of sand
for example.
Note: For deep gravel it is recommended that
the Sand program is selected.
In slippery condi tions, it may be beneficial to
pull away in a higher gear than usual.
For information on the fitment and use of snow
chains. See USING SNOW CHAINS
(page 192).
For information on the fitment and use of
winter tyres. See USING WINTER TYRES
(page 183).
Note: If the vehicle is unable to gain traction in
deep snow, switching DSC off may help. DSC
should be switched on again as soon as the
difficulty is overcome. See USING TRACTION
CONTROL (page 139).
Mud-Ruts This program should be used for
crossing terrain that is muddy,
rutted, soft, or uneven.
Sand This program should be used for
terrain which is pr edominantly soft
dry sand, or deep gravel. Note:
If the vehicle is unable to gain traction in
extremely soft, dry sand, switching DSC off
may help. DSC should be switched on again as
soon as the difficulty is overcome. See USING
TRACTION CONTROL (page 139).
If the sand to be crossed is damp/wet, and
sufficiently deep to cause the wheels to sink
into the surface, the Mud-Ruts program should
be used.
System difficulties
Note: Selection of an in appropriate special
program will not endanger th e driver, nor will it
immediately damage the vehicle. However, if
continued, use of an incorrect program will
impair the vehicle's re sponse to the terrain,
and can reduce the durability of the drive
systems.
If the system becomes pa rtially inoperable for
any reason, it may not be possible to select
special programs. A wa rning will be given
when selection of a special program is
attempted. If the Te rrain response system
becomes totally inoperabl e, all of the program
indicators will be switched off, and the
message centre will display the relevant
message.
If a participating vehicle system becomes
temporarily inoperable, the General program
will be automatically selected. Once the system
returns to normal operation, the previously
active program will be re-activated unless the
ignition has been turned off in the mean time.
Terrain response messages
Messages relating to the terrain response
system are displayed on the message centre.
See INFORMATION MESSAGES (page 99).
Most of the messages th at appear will be for
information only, and require no driver
intervention, SAND PROGRAM SELECTED for
example.

Messages that require driver intervention are
shown in the following table.
Message Meaning What to do?
PROGRAM CHANGE IN PROGRESS Conditions exist which
temporarily prevent selection of a new program. If conditions change within 60
seconds, the chosen program will be activated. If the
message is prompted by
electronic coupling overheat
the delay will be longer. A
separate message will also be displayed.
SYSTEM FAULT SPECIAL
PROGRAMS NOT AVAILABLE A fault exists which renders the
Terrain Response programs unavailable. Use extreme caution if
travelling off road, and seek qualified assistance
immediately.
RECOMMEND COMMAND
SHIFT FOR DEEP SOFT SAND In extreme sand conditions, it
may be beneficial to select
Command Shift to improve driver control. Select Command Shift if
required.

Hill descent control (HDC)
136
L
Hill descent control (HDC)PRINCIPLE OF OPERATION
HDC operates in conjunction with ABS to
provide greater control when off-road,
particularly when desc ending steep slopes.
HDC operation is fully automatic when
engaged.
During a hill descent when driving off-road,
engine braking is used to control the speed of
descent. If engine braki ng alone is insufficient
to control the vehicle's speed, HDC will slow
the vehicle using the braking system. HDC will
control the descent speed relative to the gear
selected and accelerator position.
If the vehicle is fitted with a manual
transmission, HDC should onl y be used in first,
or reverse gears. If the vehicle is fitted with an
automatic transmission, HDC should only be
used in D, R , or CommandShift 1. When in D
the vehicle will select the most appropriate
gear.
Note: HDC is automatically selected by some
of the Terrain response special programs.
Gradient release control (GRC)
With HDC activated, if the vehicle is stopped on
a slope using the footbrake, GRC will become
active. When the footbrake is released GRC will
automatically delay the brake release to allow
take up of drive, and build up of engine torque.
The brakes will then gradually release to allow
the vehicle to move smoothly away under the
control of HDC.
GRC operates in forwar d and reverse, and
requires no driver intervention.
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.

USING HDC
Selecting HDC
HDC can be selected at speeds below 80 km/h
(50 mph). To select HDC, press and release the
HDC on/off switch.
The green HDC indicator will
illuminate continuous ly at speeds
below 50 km/h (30 mph) to indicate
that HDC is fully active.
If the vehicle speed ex ceeds 80 km/h (50 mph)
HDC will disengage, and the HDC indicator will
extinguish.
If HDC has been selected, and the vehicle
speed rises above 50 km/h (30 mph) HDC is
suspended, and the HDC indicator will flash. A
message will appear in the message centre to
confirm the suspension of HDC.
HDC operation
With HDC engaged, the speed of descent can
be altered using the cruise control steering
wheel switches. + increases the speed, and —
decreases the speed.
To increase speed pr ess, and hold, the + switch
until the desired speed is achieved. When the
switch is released, the speed will be
maintained.
To decrease speed press, and hold, the —
switch until the desired speed is achieved.
When the switch is rele ased, the speed will be
maintained.
To increase or decrease speed gradually, tap
the + or — switch as required. Each tap of the
switch will increase, or decrease the speed in
increments of 0.5 km/h (0.3 mph). The
accelerator pedal can also be used to increase
speed, up to the threshold in each gear.
Note: Each gear has a pre-determined
minimum speed.
Descent speed will only increase on a slope
steep enough to pr ovide additional
momentum. Therefore, use of the + switch on
a gentle slope may not increase the speed.
When using HDC in vehicles fitted with a
manual transmission, depressing the clutch
pedal will prevent HDC from controlling the
speed of descent.

L
If the brake pedal is de pressed, HDC will be
overridden and the br akes will operate as
normal. When the brake pedal is released, HDC
will resume control of the descent.
If HDC is switched off during a descent, HDC
assistance will fade out gradually. This is to
prevent loss of control if HDC is switched off in
error. HDC will resume control when switched
back on if assistance is still required, but at the
speed the vehicle is travelling when the pedal is
released.
When driving off-road HDC can be permanently
selected, but it will only provide assistance
when the speed parameters are met.
Warning messages
Brake temperature
In extreme circumstances, the HDC system
may cause brake temperatures to exceed their
pre-set limits. If this occurs the warning
message HDC TEMPORARILY NOT
AVAILABLE SYSTEM COOLING will be
displayed in the message centre. HDC will then
fade out and become temporarily inactive.
If the vehicle is not fitted with a message
centre, then the amber HDC warning indicator
will flash.
HDC will remain unavaila ble until the brakes
reach an acceptable temperature. Once the
brakes have reached an acceptable
temperature, the message will disappear (or
the warning indicator wi ll extinguish) and HDC
will, if required, resume operation. System fault
If a fault is detected in the HDC system, HDC
FAULT SYSTEM NOT AVAILABLE will appear in
the message centre.
If the vehicle is not fitted with a message centre
the amber HDC warning indicator will
illuminate.
If the fault is detected whilst the system is
operating HDC assistance will fade out.
If a fault is detected, contact you Land Rover
Dealer/Authorised Repairer as soon as
possible.
WARNING
Do not attempt a steep descent if HDC
is inoperative, or wa rning messages are
displayed.

Electronic Traction Control (ETC)
ETC operates in conjunction with Dynamic
Stability Control (DSC) and is designed to
assist when one, or more, wheels have lost
traction.
If a wheel looses tracti on, ETC will operate the
brake on that wheel until it regains traction.
Warning indicator If a fault is detected within the ETC
system the warning indicator will

Stability control
140
L
Stability controlPRINCIPLE OF OPERATION
Dynamic Stability Control (DSC)
DSC has two main functions.
Firstly, if a wheel, or wheels, loose traction
when accelerating, it enhances Traction
Control by reducing engine torque, and
applying braking force to individual wheels.
This further improves the vehicle's ability to
pull away on slippery, or loose surfaces, and
reduces the likelihood of wheel spin when
cornering.
Secondly, DSC will apply braking force to
individual wheels in orde r to maintain vehicle
stability when cornering, changing lanes
suddenly, or manoeuvring in an emergency.
This will help to keep the vehicle on the driver's
intended path, rather than over, or under
steering. 1.
Vehicle fitted with DSC.
2. Vehicle without DSC.
Roll stability control (RSC)
RSC works in conjunction with DSC to try and
prevent vehicle roll-over. If the system senses
that the vehicle is approaching roll-over it will
reduce engine power and use the ABS system
to reduce the chance of roll-over.
WARNING
DSC is unable to compensate for driver
errors.
It is the driver's responsibility to drive with due
care and attention, in a manner which is safe
for their vehicle, it's oc cupants, and other road
users.
WARNING
No electronic system can remove the
need for safe drivin g practice. RSC can
help to maintain control of the vehicle.
It cannot regain control of the vehicle if it has
been lost, or overcome driver errors. Always
drive with due consideration for the prevailing
road and weather conditions.
