CRUISE CONTROL

DANGER
DO NOT use the cruise control in heavy
traffic, with ice/snow on the road or
during other unfavorable conditions. This
may lead to a loss of vehicle control,
causing a vehicle crash, personal injury
or death.
Engaging
To engage and set desired speed:
1 Set the cruise control switch to ON.
2 When the desired vehicle speed has been reached, momentarily press in the SET+
or SET- switch on the end of the lever.
3 To increase speed, press the SET+ switch. A momentary press of the switch (half
second or less) will bump up vehicle speed in small increments. Hold down the switch
(more than a half second) to ramp up vehicle speed. The vehicle speed will increase
as long as the SET+ switch is pressed (speed will not increase above the maximum
programmed speed). Release the switch when the desired speed has been reached. The
new set speed will be the vehicle speed when the switch is released.
4 To decrease speed, press the SET- switch. A momentary press of the switch (half
second or less) will bump down vehicle speed in small increments. Hold down the
switch (more than a half second) to ramp down vehicle speed. The vehicle speed will
decrease as long as the SET- switch is pressed (speed will not decrease below the
minimum programmed speed). Release the switch when the desired speed has been
reached. The new set speed will be the vehicle speed when the switch is released.
