Automatic speed limiter

Automatic speed limiter USING ASL
In certain conditions, such as a steep
downhill gradient, the vehicle speed may
exceed the set speed limit. This is because
engine braking is unable to maintain or
reduce the vehicle speed, driver intervention
may be required.
The ASL button allows the driver to select
between cruise control and the automatic
speed limiter. The ASL can be set to any speed
between 18 mph (30 km/h) and 150 mph (240
km/h).
Note: Although ASL only operates at speeds
between 18 mph (30 km/h) and 150 mph (240
km/h), the maximum speed can be set when
the vehicle is stationary.
SETTING A SPEED LIMIT
• Press the ASL button.
• Use the cruise control increase/decrease
buttons to set the required speed. The
message center display in the instrument
panel will show the selected speed.
• The set speed can be adjusted at any time,
using the cruise control increase/decrease
buttons.
When ASL is selected and a set speed inserted,
the engine will respond normally up to the set
speed. Further accelerator pedal pressure will
not increase the vehicle speed beyond your set
speed, unless kickdown is initiated, in which
case ASL will be suspended.
SUSPENDING ASL
ASL can be suspended by pressing the CAN
button. Applying sudden, rapid acceleration
(kickdown) will also suspend ASL.
RESUMING ASL
If ASL has been suspended, it can be reinstated
with a single press of the RES button. However,
ASL will only reinstate if the vehicle speed is
less than the current speed set in memory and
greater than 18 mph (30 km/h). The message
center will display an appropriate message if
the vehicle speed is too fast to resume ASL.
