Land Rover Discovery: Automatic speed limiter (ASL)

Land Rover Discovery (2009–2016) Owner's Manual / 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.

Automatic speed limiter (ASL)

  1. 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).

  1. SET+: Press to set or increase the speed limit. The set speed limit will be displayed in the Message centre.
  2. Press (-) to decrease the speed limit.

    The set speed limit will be displayed in the Message centre.

  3. 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.

  4. CAN: Press to temporarily suspend ASL assistance. ASL can also be temporarily suspended by applying sudden, rapid acceleration (kickdown).
