Brakes
98 Additional operating information
While anti-lock braking is designed to operate
equally effectively in off-road driving
conditions, on certain surfaces total reliance
on the system may be unwise. Anti-lock
braking cannot reliably compensate for driver
error or inexperience on difficult off-road
surfaces.
Note the following:
· Under ABS control, heavy braking on a dry
road may produce tyre noise and slight
marking of the road surface. Neither need
cause concern.
· On soft or deep surfaces such...

Warning light
The anti-lock braking system
incorporates a monitoring
system, which checks that all the electrical
components are in working order, as soon as
the starter switch is turned on and also at
frequent intervals during your journey.
The warning light on the instrument panel is
an important part of this system. The light
should illuminate for approximately 3 seconds
when the starter switch is turned to position
II and then extinguish.
If the light illuminates while driving, or
remains...

Traction control
100 ELECTRONIC TRACTION CONTROL
The purpose of electronic traction control is to
aid traction when one or more wheels are
spinning while others have good grip, eg. if
one wheel is on ice and others are on tarmac.
The system works by applying the brake to a
spinning wheel in order to transfer torque to
the remaining wheels.
NOTE:Traction control can operate up to
speeds of 62 mph (100 km/h).
Warning light
The instrument panel has a traction control
warning (TC) which illuminates for a...

Hill Descent Control
101
H2656
HILL DESCENT CONTROL
Hill Descent Control (HDC) operates in
conjunction with the anti-lock braking system
to provide greater control in off-road
situations particularly when descending
severe gradients.
To select HDC
HDC can be selected with the vehicle in any
gear, but will only operate when low range
gears are engaged with the vehicle travelling
at less than 31 mph (50 km/h).
Press the switch (illustrated above) to select
HDC.
If low range gears are engaged, the HDC...

Hill Descent Control
102 To avoid further cause for brake temperatures
to rise, engage an appropriate low gear for
steep descents and avoid descending hills at
higher than the minimum descent speed. If
the failure warning light continues to flash,
the HDC system will gradually fade out (see
HDC fade-out).
HDC fade-out
HDC fade-out gradually decreases the HDC
brake intervention with the effect that the rate
of hill descent will increase. If this occurs the
HDC information light will flash and the
warning...

H2605
WARNING
If the warning light illuminates RED a
system fault has occurred that may result in
serious damage to vehicle components.
Stop the vehicle and switch off the engine as
soon as safety permits.
Active Cornering Enhancement
(if fitted)
Active Cornering Enhancement (ACE) is a
patented feature unique to Land Rover. The
system is designed to eliminate vehicle body
lean at low cornering speeds and reduce body
lean at higher cornering speeds, while
maintaining a...

Active cornering enhancement
104 Warning light
The warning light illuminates RED when the
starter switch is turned on (to position II).
After two seconds, the RED illumination
changes to AMBER and, after a further two
seconds, the light extinguishes. This process
is a system check that takes place every time
the vehicle is used. Provided the ACE system
is operating correctly, illumination will not
occur at any other time.
If illumination occurs while driving, a fault
with the system is indicated, as...

Self-levelling suspension
105 SELF-LEVELLING SUSPENSION
(if fitted)
When the engine is running, the self-levelling
suspension system (SLS) operates
automatically on the rear of the vehicle to
maintain a level or efficient vehicle height
regardless of vehicle load.
AUTOMATIC OPERATION
If the height of the vehicle is reduced by
additional loading (passengers occupying the
occasional rear seats or the attachment of a
trailer, for example), the SLS system
automatically increases air pressure to the
springs...

Self-levelling suspension
106
H2606
To manually raise the suspension:
With the engine running and all doors fully
closed, press the fascia-mounted off-road
mode switch (see illustration). A single
warning chime will sound, the off-road
warning light on the instrument panel will
commence flashing and the rear of the vehicle
will start to rise. Once the pre-set off-road
height has been reached, the warning light will
stop flashing and illuminate constantly
instead. Constant illumination will remain
while...

Self-levelling suspension
107
NOTE:If this feature is subjected to excessive
use, the system will automatically disable to
prevent components from overheating. The
system has a cumulative total of three
minutes operation at any one time. If this is
exceeded the system will close down (partial
operation will return after a few minutes).
Remote SLS handset
The remote SLS handset is available as an
accessory from a Land Rover dealer.
Battery replacement is similar to the
equivalent process for the handset...
