Accel Control
WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
During cruise control driving, while the RES/ACC switch is ON, the motor in the cruise control actuator rotates to open the throttle valve, and increase the driving speed. Every time the RES/ACC switch is turned on instantaneously, the vehicle speed is accelerated approximately 0.93 mph (1.5 km/h).
