automated gearbox, but only with off-road function switched off.

'Master display'
NOTE: Manual shifting on a TraXon gearbox is only possible with the Eco

negative influence on the fuel consumption.
NOTE: Ex factory different customer settings are possible so, vehicles can
react different while driving with the Eco Mode function on.
8.7 ECOROLL FUNCTION
8.7.1 EcoRoll function
EcoRoll is a function of the automated gearbox designed to increase fuel savings.
These fuel savings are achieved by gaining extra momentum on slightly descending
slopes. At the bottom of the slope this extra momentum is then used to coast (roll) over
a larger distance before cruise control must react to keep the cruise control set speed.
Therefore fuel is saved.
The EcoRoll function is constantly active when the cruise control is on and, If the right
conditions are met, engaged by the automated gearbox.
These conditions include, amongst others, the vehicle mass and the slope gradient
(usually less than 1%) and are closely monitored by the vehicle's electronic systems.
EcoRoll only functions within a specific vehicle speed window. This window is
ECO
OFF
