Hand Throttle Control
Your vehicle may be equipped with a hand throttle. It is
located on the floor, to the left of the driver's seat. It can be
especially helpful in cold weather to keep your engine running
above idle speed when you leave the vehicle briefly. See
page 64 for more information on idling your engine safely.

WARNING! Do not operate the cruise control
when operating on road surfaces with poor
traction (wet, icy, or snow covered roads) or in
heavy traffic. Accelerations caused by the normal
operation of the cruise control could cause
you to lose control of the vehicle resulting in an
injury accident.
The master switch turns the cruise control ON or OFF.
The second switch allows you to SET the desired speed
or RESUME the desired speed after the cruise control
function has been interrupted.
WARNING! Do not use the hand throttle control
for cruise control or to control your road speed.
It could cause an accident and you could be
seriously injured. Always disengage the hand
throttle before driving the vehicle.
See page 65 for instructions on how to use the cruise control.
