Setting At A Desired Speed; Cancelling The Preset Speed - Lexus GS300 1998 Owner's Manual

STARTING AND DRIVING

Setting at a desired speed

31G012–1
The transmission must be in "D" or "4" before you set the
cruise control speed.
Bring the vehicle to the desired speed, press the control lever
downward in the "SET/COAST" direction and release it.
This sets the vehicle at that speed. Now you may take your
foot off the accelerator pedal. If you need acceleration – for
example, when passing – depress the accelerator pedal
enough for the vehicle to exceed the set speed. When you
release the accelerator pedal, the vehicle will return to the
speed set prior to the acceleration.

Cancelling the preset speed

You can cancel the preset speed by either of the following:
a. Pulling the control lever in the "CANCEL" direction.
b. Depressing the brake pedal.
282
If the vehicle speed falls below about 40 km/h (25 mph), the
preset speed will be automatically cancelled.
If the vehicle speed drops 16 km/h (10 mph) below the preset
speed, the preset speed will also automatically be cancelled.
If the preset speed automatically cancels out for other than
these reasons, have your vehicle checked by your Lexus
dealer at the earliest opportunity.
