▷ Each time the rocker switch is tapped to the
resistance point, the set speed increases or
decreases by 1 mph/1 km/h.
▷ Each time the rocker switch is pressed past
the resistance point, the desired speed
changes by a maximum of 5 mph/10 km/h.
The maximum speed that can be set de‐
pends on the vehicle.

point and holding it: vehicle accelerates or
decelerates without pressure on the acceler‐
ator pedal.

the vehicle to accelerate more rapidly.
Continuing cruise control

rupted.
