Hill descent control (HDC)
R
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.

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 control
R
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.
Before driving off-road
Before venturing off-ro ad it is absolutely
essential that inexperienced drivers become
fully familiar with the vehicle's controls. In
particular, CommandShift , Hill Descent Control
(HDC), and the Terrain Response system.
Basic information a nd 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

Stability control

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.

Stability control
R
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.

L
Fuel and refuellingSAFETY PRECAUTIONS FUEL QUALITY
Petrol engined vehicles
Octane rating
The minimum octane rating for fuel used is 91
RON. The vehicle will run on lower ratings, but
it may cause pronounced engine knock or
pinking. If the pinking is severe it can cause
damage to the engine, fuel, and emission
control systems.
Note: Occasional, light , engine knock
experienced while accelera ting or climbing hills
is acceptable.
WARNINGS
Petroleum gasses are highly
flammable, have a low flash point, and
are explosive, especially in confined
spaces. Avoid exposing the gasses to any
potential sources of ignition as the resulting
fire and explosion may cause serious injuries
and/or death.
Only use containe rs specifically
designed for carrying fuel, and alway
remove them from the vehicle to fill
them. Failure to do so may result in spillage,
and cause a fire.
Switch off the engine when refuelling,
as it is both a source of extreme
temperatures, and electrical sparks.
The resulting fire a nd explosion may cause
serious injury and death.
Switch off any personal electronic
devices such as mobile phones, or
music players. They have the potential
to cause electrical sparks. The resulting fire
and explosion may caus e serious injury and
death.
Do not smoke, use a naked flame, or
cause sparks. The resulting fire and
explosion may caus e serious injury
and death.
Do not overfill the fuel tank. Overfilling
may cause spillage when the vehicle is
driven. Spillage may also occur if the
fuel expands in high ambient temperatures.
CAUTIONS
Do not use leaded fuels, lead
substitutes, or fuel additives. Doing so
can cause damage to the engine, fuel,
and emission control systems.
Only use high quality petrol, as using
lower quality fuels ca n cause damage to
the engine, fuel, and emission control
systems.
Fuel system cleaning agents should not
be used, unless approved by Land
Rover. Unapproved products may be
harmful to fuel system components on your
vehicle.

Alternative fuels for petrol engines
Ethanol
Fuels containing up to 10% Ethanol (grain
alcohol) may be used. Ensure that the fuel has
octane ratings no lower than those
recommended for unleaded fuel. Most drivers
will not notice any opera ting difference with
fuel containing Ethanol . If a difference is
detected, the use of c onventional unleaded fuel
should be resumed.
Methanol
Some fuels contain Methanol (Methyl or wood
alcohol). If you use fuel s containing Methanol
the fuels must also contain co-solvents and
corrosion inhibitors for Methanol. Also, do not
use fuels which contain more than 3%
Methanol even if they contain co-solvents and
corrosion inhibitors. Fuel system damage or
vehicle performance problems resulting from
the use of such fuels is not the responsibility of
Land Rover, and may not be covered under the
warranty. Methyl Tertiary Butyl Ether (MTBE)
Unleaded fuel containing an oxygenate known
as MTBE can be used provided that the ratio of
MTBE to conventional fuel does not exceed
15%. MTBE is an Ether based compound
derived from Petroleum, which has been
specified by several refi ners as the substance
to enhance the Octane rating of fuel.
Reformulated gasoline
Several petroleum companies have announced
the availability of refo rmulated fuels. These
fuels are specially formulated to further reduce
vehicle emissi ons. Land Rover fully supports
all efforts to protect and maintain ambient air
quality, and encour ages the use of
reformulated gasoline where available.
Diesel engined vehicles
Note: Land Rover vehicle's are capable of
running with up to a 5% blend of bio-diesel in
accordance with European Standard EN590.
Sulphur content
The Sulphur content of diesel used in Land
Rover vehicles shoul d not exceed 0.3%.
In some countries dies el will contain higher
levers of Sulphur, whic h will require reduced
service intervals to reduce the effects on
engine components. If in doubt contact a local
Land Rover Dealer/Aut horised Repairer for
advice.
CAUTIONS
This vehicle is not suitable for use with
fuels containing more than 10%
Ethanol.
Do not use E85 fuels (85% Ethanol
content). Equipment necessary for the
use of fuels containing more than 10%
Ethanol is not fitted to this vehicle. If E85 fuels
are used, serious engine and fuels system
damage will occur.
CAUTION
Wherever possible avoid using fuel
containing Methanol.

RUNNING OUT OF FUEL
Note: If the vehicle does run out of fuel, a
minimum of 4 litres (0 .8 gallons) will be
required to restart the engine. The vehicle will
need to be driven 1.6-5 km (1-3 miles) in order
to reset the engine management and
monitoring systems.
Note: If the vehicle does run out of fuel,
seeking qualified assistance is advisable.
FUEL CUT-OFF
The fuel system cut-off forms part of the
Supplementary Restraint System (SRS) fitted
to your vehicle. Following an impact, and
depending on the severity, the fuel pump may
be switched off.
Resetting the fuel cut-off
1. Switch the ignition off and wait for one
minute.
2. Turn the ignition on for 30 seconds.
3. Check the vehicle thor oughly for fuel leaks.
If a leak is detected switch the ignition off
immediately.
• Do not start the vehicle if a leak is
present. Seek qualifi ed advice, and have
the vehicle recovered.
4. If no leaks are detected, start the vehicle.
FUEL FILLER FLAP
The fuel filler flap is located on the right-hand
side of the vehicle, at the rear.
1. Ensure that the vehicle is fully unlocked,
and pull the fuel filler flap open.
2. Twist the cap anti-clockwise to undo.
• Ensure that you re ad, understand, and
fully comply with all warnings and
instructions given on the label affixed to
the inside of the fuel filler flap.
3. Use the retaining clip to keep the filler cap
out of the way whilst fuelling.
CAUTION
Avoid running out of fuel. Doing so can
cause damage to the vehicle's engine,
fuel, and emission control systems.
WARNING
The fuel cut-off s hould never be reset
if you can smell fuel , or a leak can be
seen. Doing so can lead to a fire which
may cause personal injury or death.
