Traction Control
130
Trac tion  Co ntrolELECTRONIC TRACTION CONTROL
The purpose of electronic traction control is to 
maintain forward or rearward momentum of the 
vehicle when one or more wheels are spinning 
while others have good grip, e.g. 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).

Hill Descent Control
131
Hill Descent ControlHILL 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 the transfer 
gearbox is in 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 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 
chime will sound for the period that HDC takes 
to fade. HDC will be disabled completely once 
the descent is complete. 
If required (e.g. the angle of the descent levels 
out significantly), fade-out may be achieved 
deliberately by deselecting HDC while the 
system is...

ACTIVE CORNERING ENHANCEMENT*
CAUTION: 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. Seek qualified assistance 
immediately.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...

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...

Self-levelling Suspension

Self-levelling SuspensionSELF-LEVELLING SUSPENSION*
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...

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...

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
If your vehicle is equipped with SLS, the remote 
SLS handset is available as an 
accessory from a Land Rover retailer. 
Battery replacement is...

WARNING
The park distance control is not infallible; it is 
for guidance only! The sensors may not be 
able to detect certain types of obstruction 
(narrow posts or small narrow objects, small 
objects close to the ground and some objects 
with dark, non-reflective surfaces, for 
example).
The parking system assists the driver when 
manoeuvring the vehicle into a parking space, 
or anywhere that there are obstacles that...

Towing

Towing
TOWING
The torque ranges of Land Rover engines allow 
maximum-weight loads to be pulled smoothly 
from standstill, and reduce gear changing on 
hills or rough terrain. The suspension is 
designed to cope with a heavy trailer load 
without upsetting the balance or feel of the 
vehicle. Details of gross maximum towed 
weights are listed on the following pages and in 
the General Data section (see ‘TOWING 
WEIGHTS’, page 234).
WARNING
To preserve the vehicles handling and 
stability, only...
