The system can be set up for connection of the last axle for
reversing, even if ATC is disabled. Otherwise, only applies in ATC
position 3.
The setup can only be modified by an authorized service
technician.
ATC Position 3: activated
Is used for all types of operating conditions. This is the basic mode
and should be used as much as possible.
The machine senses wheel speed and steering angle. 4–wheel
drive and 6-wheel drive are controlled automatically and
independent of each other.
NOTE!
The machine's steering performance is reduced when using all
differential locks.
Symbols for all differential locks and 6-wheel drive are activated
on the instrument panel.
Foot control 6-wheel drive
Is used when operating where maximum drive is required.
Pressing the foot control activates 6-wheel drive. The differential
locks in all three axles are also activated. All wheels rotate at the
same speed. When the control is let up, drive reverts to the
previous mode.
Snow chains
NOTE!
When operating with anti-slip devices (snow chains), 6-wheel
drive should not be engaged.
NOTE!
Volvo does not recommend use of snow chains. If snow chains
are still installed despite this, it shall be done in consultation with
the snow chain's manufacturer. It is important that snow chains
are installed correctly since the space is limited and the machine
can be damaged in case of incorrect installation. Snow chains can
only be installed if the tyre dimension 23.5 R25 is used on the
machine.
