OPTISPEED - Continuously vari-
able reduction in driving speed or
hydraulic functions (variant)
The OPTISPEED variant assists the driver by
providing two additional functions:
• Reduction of driving speed when turning
(Curve Speed Control)
• Reduction in speed of hydra
ulic functions
Depending on the truck equipment, the two
functions may be present either individually or
together.
Reduction of driving speed when turning
(Curve Speed Control)
This variant optimises the speed of the truck
as the steering angle increases. This assists
the driver in handling the truck.
DANGER
The stability limits defined by the laws of physics
are still in effect even when the "reduction of speed
when turning" function is active. There is a risk of
tipping!
– Before using this function, familiarise yourself
withthe change to the truck’s drivingand steering
characteristics.
DANGER
Risk of tipping if cornering speed is too high!
If the controller is switched off or fails while driving,
the driving speed will no longer be reduced on
cornering.
– Do not switch off the truck while driving.
– Actuate the emergency off switch in emergen-
cies only.
– Always adapt your driving style to the conditions.
– Do not take risks with safety.
In the following situations, the truck may
overturn in extreme cases:
• Cornering too fast on uneven or inclined
roadways.
• Turning the steering wheel sharply while
driving.
