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.
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

Hill descent control (HDC)
138
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.

Traction controlUSING TRACTION CONTROL
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
illuminate.

USING STABILITY CONTROL
DSC
DSC is activated automatically each time the
engine is started, and is automatically selected
by some of the Terrain Response Special
programs.
Note: In the majority of dr iving situations, and
particularly on-road, it is recommended that
you do not turn DSC off.
Deactivating DSC
In some driving conditions it may prove helpful
to deactivate DSC to improve traction. These
conditions include :-
• Rocking the vehicle out of a hollow.
• Rocking the vehicle out when the wheels
have sunk into the surface.
• Pulling away in deep snow, or a loose
surface.
• Driving along deep ruts.
• Driving through deep mud. To deactivate DS
C, press, and
briefly hold, the DSC button. The
DSC warning indicator will
illuminate continuously as a reminder that DSC
is deactivated.
Note: Deactivating DSC will have no effect
upon the operation of Traction Control.
Reactivating DSC
DSC is reactivated by :-
• pressing, and briefly holding the DSC
button.
• starting the engine.
• selecting a new Terra in Response special
program.
DSC system fault
If a fault is detected the DSC warning lamp will
illuminate continuously when DSC has not
been deactivated.
CAUTION
Driving with DSC deactivated puts
additional loads on the brakes.
Wherever possible, drive with DSC
activated.

Maintenance
R
MaintenanceGENERAL INFORMATION
Regular systematic maintenance is the key to
ensuring the continued re liability and efficiency
of your vehicle.
Maintenance is the owne r's responsibility and
you must ensure that owner maintenance
operations, oil services, inspections and brake
fluid and coolant changes are carried out when
required and according to the manufacturer's
recommendations.
The routine maintenance requirements for your
vehicle are shown in the Service Portfolio book.
Most of this necessar y workshop maintenance
requires specialised knowledge and
equipment, and should preferably be entrusted
to a Land Rover Dealer/Authorised Repairer.
Service intervals
On vehicles fitted with a message centre, an
upcoming service interval will be notified to the
driver in one of two ways. As a distance left to
travel, or a number of da ys remaining. Once the
distance or time are ex ceeded the display will
show a negative value (-) to indicate that a
service is overdue.
When the ignition is turned on the Odometer
display will show the service information for
five seconds. 1.
Distance to service.
2. Distance by which service is overdue.
1. Number of days to service.

One or both types of serv ice interval (distance
and time) may be displayed. For example, if an
engine oil service is du e based on mileage, and
a brake fluid change is due based on time, both
distance and time c ountdowns will display.
Service Portfolio
The Service Portfolio book includes a Service
Record section, which enables a record to be
kept of all the servicing and inspections that are
carried out on the vehicle. This section of the
book also has an area for brake fluid changes
to be recorded.
Ensure your service provider signs and stamps
the book after each se rvice and inspection.
Owner Maintenance
In addition to the routine maintenance, a
number of simple checks must be carried out
more frequently. Advice is given on the pages
that follow.
Daily checks
• Operation of lamps, horn, direction
indicators, wipers, washers and warning
indicators.
• Operation of seat belts and brakes.
• Look for fluid deposits underneath the
vehicle that might indicate a leak.
Weekly checks
• Engine oil level. See ENGINE OIL CHECK
(page 162).
• Engine coolant check. See ENGINE
COOLANT CHECK (page 163).
• Brake/clutch fluid level. See BRAKE AND
CLUTCH FLUID CHECK (page 165). •
Power steering fluid level. See POWER
STEERING FLUID CHECK (page 166).
• Screen washer fluid level. See WASHER
FLUID CHECK (page 167).
• Tyre pressure s and condition.
• Operate air conditioning.
Note: The engine oil leve l should be checked
more frequently if the vehicle is driven for
prolonged periods at high speeds.
Driving in arduous conditions
When a vehicle is operated in extremely
arduous conditions, more frequent attention
must be paid to servicing requirements.
For example, if your vehicle experiences deep
wading conditions, even daily servicing could
be necessary to ensure the continued safe and
reliable operation of the vehicle.
Arduous driving conditions include:
• Driving in dusty and/or sandy conditions.
• Driving on rough and/or muddy roads
and/or wading.
• Driving in extremely hot conditions.
• Towing a trailer or driving in mountainous
conditions.
Contact a Land Rover Dealer/Authorised
Repairer for advice.
Emission control
Your vehicle is fitted with various items of
emission and evaporative control equipment,
designed to meet sp ecific territorial
requirements. You should be aware that
unauthorised replacemen t, modification or
tampering with this equipment by an owner or
repair shop, may be unlawful and subject to
legal penalties.
CAUTION
Any significant or sudden drop in fluid
levels, or uneven tyre wear, should be
reported to a qualified technician without
delay.

Maintenance
R
In addition, engine se ttings must not be
tampered with. These have been established to
ensure that your vehicle complies with
stringent exhaust em ission regulations.
Incorrect engine settings may adversely affect
exhaust emissions, engi ne performance and
fuel consumption. The y may also cause high
temperatures, which will result in damage to
the catalytic converter and the vehicle.
Road testing dynamometers (rolling
roads)
Because your vehicle is equipped with anti-lock
brakes and four wheel drive, it is essential that
any dynamometer testing is carried out only by
a qualified person, familiar with the
dynamometer testing an d safety procedures
practised by Land Rove r Dealers/Authorised
Repairers.
