Cruise Control System: Overview Lexus LX J80

DESCRIPTION

WARNINGDeactivate air bag system before performing any service operation. «AIR BAG RESTRAINT SYSTEM» article. DO NOT apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.

Cruise control system consists of Cruise Control Electronic Control Unit (CC ECU), actuator, control cable, speed sensor, cruise control switch, stoplight switch, park/neutral switch and wiring. (Схема №1)

System allows vehicle to cruise at a desired speed greater than 25 MPH. Speed control will cancel when brake pedal is depressed, CANCEL switch is activated or transmission shift lever is moved to "N" position. If vehicle speed slows to less than 25 MPH or drops 10 MPH less than preset speed, speed control will also cancel.

OPERATION

Pressing cruise ON-OFF (main) switch to ON position, activates cruise control system. CRUISE indicator light in instrument cluster comes on to indicate activation of system. To set speed, increase vehicle speed to desired speed (must be over 25 MPH). Set cruise control switch to SET/COAST position and release switch. Vehicle speed will now be maintained. To increase speed, depress accelerator pedal enough to exceed set speed. When accelerator pedal is released, speed will return to speed previously set.

To cancel set speed, set cruise control switch to CANCEL position, depress brake pedal or place shift lever in "N" position. If vehicle speed slows to less than 25 MPH, set speed will automatically cancel. If vehicle speed drops 10 MPH less than preset speed, set speed will also automatically cancel.

Setting cruise control switch to RES/ACC position allows vehicle to return to set speed before cancellation. Setting cruise control switch to RES/ACC position and keeping it there gradually increases vehicle speed. Setting cruise control switch to SET/COAST position and keeping it there gradually decreases vehicle speed.
