OFF-ON-R/A Switch


Object Number: 276101  Size: SH

The OFF-ON-R/A switch has the following 3 positions:

    • The ON position
        The ON position turns the cruise control system ON.
    • The OFF position
        The OFF position turns the cruise control system OFF.
    • The R/A position
        The R/A switch position has the following 3 main functions:
       - Resume
       - The system will enter the resume mode when the OFF-ON-R/A switch is held in the R/A (Resume/Accelerate) position momentarily. The vehicle speed must exceed 40 km/h (25 mph) at the time of activation in order for the cruise control operation to return to the last cruise speed setting.
       - Accelerate
       - The system will enter the accelerate mode when the OFF-ON-R/A switch is held in the R/A position for more than one second.
       - To increase the cruise speed, the vehicle must be traveling at least 40 km/h (25 mph) and the ON-OFF-R/A switch held in the R/A position until the vehicle reaches the desired cruise speed.
       - The system will maintain the new cruise speed when the OFF-ON-R/A switch is released to the ON position.
       - Tap-Up
       - This function increases the cruise speed by increments of 2 km/h (1 mph). One tap produces an increase of 2 km/h (1 mph). The cruise must be engaged and operating in order to use this function.
       - Press the OFF-ON-R/A switch toward the R/A position and release quickly or tap the lever in order to operate the tap-up function. Do not hold the lever in the R/A position or the system will go into the accelerate mode.

SET/CRUISE Button Switch

The cruise control SET/CRUISE button switch is located in the end of the turn signal and multifunction switch. The switch has the following 3 main functions:

    • Set
    • Coast
    • Tap-Down

SET

The cruise speed sets when the following actions occur:

    • The SET/CRUISE button switch is pressed and released.
    • The OFF-ON-R/A switch is in the ON position.
    • The vehicle speed exceeds 40 km/h (25 mph).

The cruise speed sets at the speed at which the vehicle is travelling when the button switch is released. The cruise speed will be within 2 km/h (1 mph) of the engaged speed.

The system will cruise until one of the following actions occurs:

    • The OFF-ON-R/A switch is moved to the OFF position.
    • The brake pedal is pressed.
    • The ignition switch is turned to the OFF position.

CRUISE

The driver can increase or decrease the cruise speed by completing the following actions:

    • Increase
        Press and hold the SET/CRUISE button switch. This action applies load to the acceleration pedal to a desired cruise speed then releases the SET/CRUISE button switch.
        When the vehicle increases to the desired cruise speed, release the SET/CRUISE button switch. This action will set the new cruise speed.
    • Decrease
        Fully press and hold the SET/CRUISE button switch. This action disengages the cruise system and allows the throttle to return to the idle position.
    • When the vehicle slows to the desired cruise speed, release the SET/CRUISE button switch. This action will set the new cruise speed.

TAP-DOWN

The tap-down function permits the driver to decrease the cruise speed in increments of 2 km/h (1 mph). One tap produces a decrease of 2 km/h (1 mph). The cruise must be engaged and operating in order to use this function.

Press and quickly release or tap the SET/CRUISE button switch in order to operate the tap-down function. Holding the button inward will cause the system to go into the COAST mode.

Press the accelerator at any time in order to accelerate while the cruise system is operating. The vehicle will return to the last set cruise speed after the accelerator is released.
