Land Rover Discovery: Automatic speed limiter (ASL)
ASL CONTROLS
ASL allows a speed limit to be set that the
driver does not wish to exceed. When a
speed has been set, the engine will
respond normally up to the set speed.
Further accelerator pressure will not
increase the speed beyond the set speed
unless sudden, rapid acceleration
(kickdown) is applied. If kickdown is
initiated, ASL will be suspended. ASL will
reactivate once the vehicle's speed drops
below the set speed.
In certain conditions, such as a
steep downhill gradient, the
vehicle's speed may exceed the
set speed limit. This is because
engine braking is unable to
maintain or reduce the vehicle's
speed.

- LIM: Press to switch between Cruise
control and ASL. The ASL indicator will
illuminate when ASL is active. The
Cruise control and ASL systems cannot
be used simultaneously.
When the vehicle's ignition is
switched on, the previous state,
either Cruise control or ASL, will
automatically be recalled and made
active. The set speed will not be
recalled.
Note: ASL operates at all vehicle
speeds. A vehicle speed can be set
from upwards of 32 km/h (20 mph).
- SET+: Press to set or increase the
speed limit. The set speed limit will be
displayed in the Message centre.
- Press (-) to decrease the speed limit.
The set speed limit will be displayed
in the Message centre.
- RES: Press to resume ASL assistance.
ASL will only resume if the vehicle's
speed is less than the set speed and
greater than 32 km/h (20 mph). If these
criteria are not met, a message will be
displayed in the Message centre.
- CAN: Press to temporarily suspend
ASL assistance. ASL can also be
temporarily suspended by applying
sudden, rapid acceleration (kickdown).
