(e) Resetting to a faster speed
Push the lever up in the “+ RES” direction and hold it. Release
the lever when the desired speed is attained. While the lever
is held up, the vehicle will gradually gain speed.

set speed is less than 5 km/h (3 mph), the set speed can be
increased 1.6 km/h (1 mph) each time by pushing the lever up
in the “+ RES” direction quickly within 0.6 seconds.

− SET” direction and hold it.
Release the lever when the desired speed is attained. While

However, a faster way to reset is to accelerate the vehicle and
then push the lever down in the “ − SET” direction.

control mode, engine braking will not be enabled because this

to a slower speed with the cruise control lever or depress the
brake pedal. If you use the brake pedal, cruise control is
cancelled.
With automatic transmission (multi −mode type) —
Even if you downshift from “D” or “5” (fifth range) to “4” (fourth

will not be enabled because this mode is not cancelled. To
decrease the vehicle’s speed, reset to a slower speed with the
cruise control lever or depress the brake pedal. If you use the
brake pedal, cruise control is cancelled.
