O When driving on a road surrounded by a structure, such as in a tunnel or on
a bridge
O While the vehicle speed is decreasing to the set speed after the vehicle
accelerates by depressing the accelerator pedal
O When the road curves or when the lanes
are narrow
O When steering wheel operation or your
position in the lane is unstable

To change the set speed, operate the lever until the desired set speed
is obtained.
Increases the speed
Decreases the speed
Fine adjustment: Momentarily
move the lever in the desired direc-
tion.
Large adjustment: Hold the lever in
the desired direction.
The set speed will be increased or decreased as follows:
Fine adjustment: By approximately 1.0 km/h (0.6 mph) each time the lever
is operated.
Large adjustment: The set speed can be increased or decreased continu-
ally until the lever is released.
Pulling the lever toward you
cancels the constant speed
control.
The speed setting is also canceled
when the brakes are applied or the
clutch pedal (manual transmission
only) is depressed.
Pushing the lever up resumes
the constant speed control.
Resuming is available when the vehicle speed is more than approximately
30 km/h (20 mph).
