Hill Des cen t C ontrolHILL 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 at any speed if LOW range 
is selected in the transfer gearbox, and can be 
selected at up to 20 mph (35 km/h) if the 
vehicle is in HIGH range. The HDC ‘Information’ 
warning light in the instrument pack will 
illuminate...

Hill Descent Control
161
If the brake pedal is depressed when HDC is 
active, HDC is overridden and the brakes will 
perform as normal (a pulsation might be felt 
through the brake pedal). If the brake pedal is 
then released, HDC will recommence operating 
at a reduced speed.
In extreme circumstances, the HDC system 
may cause brake temperatures to exceed their 
pre-set limits. If this occurs, ‘HDC TEMP. NOT 
AVAIL.’ will be displayed in the message center. 
HDC will then fade out (warning light...

Ele ctron ic  Air Sus pen sionELECTRONIC AIR SUSPENSION (EAS)
When the engine is running, the EAS operates 
automatically on the vehicle to maintain a level 
or efficient vehicle height regardless of vehicle 
load.
If the height of the vehicle is reduced by 
additional loading (attachment of a trailer, for 
example), the system automatically increases 
air pressure to the springs to compensate for 
the additional weight or changed angle of the 
vehicle. Similarly, if loads...

Before operating EAS
Remember, even if a change of ride height is 
selected, it will NOT take place if any door is 
open.
NOTE: Frequent changes between ride heights 
could cause the compressor to overheat. If this 
occurs, EAS will be fully operational again after 
a few minutes when the compressor has 
cooled.

Push the switch up or down to raise or lower 
the vehicle to the next ride height setting.

OFF-ROAD HEIGHT
At low speeds, the vehicle height 
can be raised to increase ground 
clearance for when driving 
off-road.
WARNING
DO NOT select off-road height while driving 
on the road, or when the suspension has been 
lowered below standard ride height - any 
sudden or unexpected change to the vehicles 
height or attitude could cause an 
inexperienced driver to lose control, or 
disturb the load/weight distribution within the 
vehicle. 
DO NOT attempt to select off-road...

165
NOTE: If the vehicle speed increases to more 
than 20 mph (30 km/h), when the vehicle is at 
access height, the EAS will automatically 
reselect standard ride height.
If the vehicle is travelling at above 50 mph 
(80 km/h) when access preselect is requested, 
the standard ride height indicator light flashes 
to indicate that the request has not been 
performed.
Access mode should only be selected whilst the 
vehicle is moving. In extreme circumstances, if 
it is necessary to...

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. A smooth start will be 
achieved with trailers over 4400 lb (2000 kg) by 
moving off in low range then changing to high 
range while on the move.
The suspension will automatically be set to 
standard height when the towing electrical 
socket is utilised and is designed to cope with a 
heavy trailer load without upsetting...

Balancing the combination
To ensure optimum stability, it is essential that 
the trailer adopts a level aspect. In other words, 
the trailer must be level with the ground, with 
the towing hitch and trailer drawbar set at the 
same height (note the illustration at the top of 
the page). This is particularly important when 
towing twin axle trailers!
•The trailer should be level with the ground 
when loaded.
•The height of the drawbar hitch point should 
be set so that the trailer is level when...

Towing guidelines
When preparing your vehicle for towing, pay 
careful attention to the trailer manufacturers 
recommendations and observe the following 
guidelines:
•Ensure that the towing vehicle tire pressures 
are correct and that the trailer tire pressures 
are as recommended by the trailer 
manufacturer.
•Within the limits quoted, choose a draw bar 
that allows for a level attitude of the trailer 
and vehicle.
•Check the operation of trailer brakes and 
lights.
•For maximum stability,...

WARNING
The tongue weight plus the combined weight 
of the vehicles load-carrying area and rear 
seat passengers must never exceed the 
specified maximum rear axle load (see 
‘TOWING WEIGHTS’, page 280).
WARNING
DO NOT exceed the gross weight or axle loads 
stated on the certification label attached to 
the vehicle. Exceeding allowable vehicle and 
axle loads will increase the risk of tire or 
suspension failure, increase vehicle brake 
stopping distance, and adversely affect 
vehicle handling...
