Tapping RESUME ACCEL once will result in a 1 mph
(2 km/h) speed increase. Each time the lever is tapped,
speed increases so that tapping the lever three times will
increase speed by 3 mph (5 km/h).
To decrease speed while Electronic Speed Control is ON,
push down and hold SET DECEL. Release the lever when
the desired speed is reached, and the new speed will be
set.
Tapping the SET DECEL button once will result in a
1 mph (2 km/h) speed decrease. Each time the button is
tapped, speed decreases.
NOTE: The Electronic Speed Control System has been
designed to shut down if multiple speed control switch
functions are operated simultaneously in order to ensure
proper operation. If this occurs, the system can be
reactivated by pushing the speed control switch ON/
OFF button and resetting the desired vehicle SET speed.
To Accelerate For Passing
Depress the accelerator as you would normally. When the
pedal is released, the vehicle will return to the set speed.
Using Electronic Speed Control On Hills
The transmission may downshift on hills to maintain the
vehicle set speed.
NOTE: The Electronic Speed Control System maintains
speed up and down hills. A slight speed change on
moderate hills is normal.
On steep hills a greater speed loss or gain may occur so
it may be preferable to drive without Electronic Speed
Control.
