Controls/Features
Steering Column and Switches
The steering column contains switches and levers to aid in the
comfort of the operator and to assist the operator while driving
the vehicle.
1. Washer/Wiper Control - The windshield washer, along with
the windshield wipers, is controlled by the WASHER/WIPER
knob on the turn signal switch lever. To operate the windshield
washer, push in on the wiper knob to spray solution on the
windshield. Wipers will start wiping and continue for two cycles.
Multi-function Switch - The multi-function turn signal switch
is mounted on the left side of the steering column below the
steering wheel.
2. Signaling For A Turn - When signaling your intention to make
a turn, move the turn signal lever up or down to the “full turn”
position which is past the point of resistance. On some models
the switch will automatically cancel if the steering wheel is turned
a large enough degree. On other models the switch does not
automatically cancel and will require manual cancellation.
Lane Change – The turn signal lever includes a “lane change”
feature which allows the operator to signal the intention to
change lanes without locking the switch into the full turn
position. To use this feature, move turn signal lever up or down
to the point where resistance to movement is felt.
The turn
signal lever will return to the OFF position when released.
3. Windshield Wiper - The electric wiper has two speeds
(hi-low), which can be operated by rotating the WASHER/WIPER
knob.
The optional intermittent control provides five wiper
ON/OFF cycle intervals, varying from 2 to 14 seconds. This is
done by rotating the wiper control from the wiper OFF position
to the any of the five intermittent wiper interval positions.
Automatic Intermittent Interval Control (Optional) – This
feature automatically changes the wiper speed from HIGH or
LOW to the slowest intermittent speed when the parking brake
has been set, and the wipers have been on for a predetermined
length of time. When the parking brake is released, the wipers
return to their previous speed.
