Frelander 2. Manual - part 714
Terrain response
134
L
This program should be selected once the need
for a special program has passed. Once the
special program has been deselected, all of the
vehicle systems will return to their normal
settings except HDC. HDC will remain active if
it was selected manually.
Grass-Gravel-Snow
This program should be used
where a firm surface is covered
with loose, or slippery material.
Surfaces covered in water, ice, slime, grass,
gravel, shale, pebbles, or a thin coating of sand
for example.
Note: For deep gravel it is recommended that
the Sand program is selected.
In slippery conditions, it may be beneficial to
pull away in a higher gear than usual.
For information on the fitment and use of snow
chains. See USING SNOW CHAINS
(page 192).
For information on the fitment and use of
winter tyres. See USING WINTER TYRES
(page 183).
Note: If the vehicle is unable to gain traction in
deep snow, switching DSC off may help. DSC
should be switched on again as soon as the
difficulty is overcome. See USING TRACTION
CONTROL (page 139).
Mud-Ruts
This program should be used for
crossing terrain that is muddy,
rutted, soft, or uneven.
Sand
This program should be used for
terrain which is predominantly soft
dry sand, or deep gravel.
Note: If the vehicle is unable to gain traction in
extremely soft, dry sand, switching DSC off
may help. DSC should be switched on again as
soon as the difficulty is overcome. See USING
TRACTION CONTROL (page 139).
If the sand to be crossed is damp/wet, and
sufficiently deep to cause the wheels to sink
into the surface, the Mud-Ruts program should
be used.
System difficulties
Note: Selection of an inappropriate special
program will not endanger the driver, nor will it
immediately damage the vehicle. However, if
continued, use of an incorrect program will
impair the vehicle's response to the terrain,
and can reduce the durability of the drive
systems.
If the system becomes partially inoperable for
any reason, it may not be possible to select
special programs. A warning will be given
when selection of a special program is
attempted. If the Terrain response system
becomes totally inoperable, all of the program
indicators will be switched off, and the
message centre will display the relevant
message.
If a participating vehicle system becomes
temporarily inoperable, the General program
will be automatically selected. Once the system
returns to normal operation, the previously
active program will be re-activated unless the
ignition has been turned off in the mean time.
Terrain response messages
Messages relating to the terrain response
system are displayed on the message centre.
See INFORMATION MESSAGES (page 99).
Most of the messages that appear will be for
information only, and require no driver
intervention, SAND PROGRAM SELECTED for
example.
