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.
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 30 km/h (18 mph) and 240 km/h (150
mph).
Note: Although ASL only operates at speeds
between 30 km/h (18 mph) and 240 km/h (150
mph), 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 centre 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 30 km/h (18 mph). The message
centre will display an appropriate message if
the vehicle speed is too fast to resume ASL.
