OFF-ON-R/A Switch

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

OFF: The OFF position turns the cruise control system OFF.

ON: The ON position turns the cruise control system ON.

R/A: 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 momentarily held in the R/A (resume/accelerate) position. 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 1 second.
        Complete the following steps in order to increase the cruise speed:
       - Accelerate the vehicle to at least 40 km/h (25 mph).
       - Hold the OFF-ON-R/A switch in the R/A position until the vehicle reaches the desired cruise speed.
       - Release the OFF-ON-R/A switch to the ON position in order for the system to maintain the new cruise speed.
    • Tap-Up
        The tap-up function increases the cruise speed by increments of 2 km/h (1 mph). One tap equals a 2 km/h (1 mph) increase.
        In order to use the tap-up function, perform the following steps:
       - Engage and operate the cruise.

   Important: Do not hold the lever in the R/A position or the system will go into the accelerate mode.

       - Press and quickly release the OFF-ON-R/A switch toward the R/A position or tap the lever.

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: The cruise speed sets after the following steps are performed:

  1. Depress and release the SET/CRUISE button switch.
  2. Turn the OFF-ON-R/A switch to the ON position.
  3. Accelerate the vehicle speed to at least 40 km/h (25 mph).
  4. The cruise speed sets at the speed at which the vehicle was traveling when the button was released. The vehicle cruise speed will be within 2 km/h (1 mph) of the engaged speed.

    The system will cruise until you perform one of the following actions:

    • Turn the OFF-ON-R/A switch to the OFF position.
    • Depress the brake pedal.
    • Turn the ignition OFF.
CRUISE: You can increase or decrease the cruise speed when the SET/CRUISE button switch is fully pressed and held.

Complete the following steps in order to increase the cruise speed:

  1. Press and hold in the SET/CRUISE button switch.
  2. Accelerate by applying load to the acceleration pedal to a desired cruise speed.
  3. Release the SET/CRUISE button switch in order to set the new cruise speed.

In order to decrease the cruise speed, perform the following steps:

  1. Press and hold in the SET/CRUISE button switch.
  2. Disengage the cruise system, which allows the throttle to return to the idle position.
  3. When the vehicle has slowed to the desired cruise speed, release the SET/CRUISE button. This procedure allows the vehicle to travel at a new set speed.
TAP-DOWN: Tap-down decreases the cruise speed by 2 km/h (1 mph) increments. One tap equals a 2 km/h (1 mph) decrease.

Complete the following steps in order to use the TAP-DOWN feature, perform the following steps:

  1. Engage and operate the cruise.
  2. Important: Do not hold the SET/CRUISE button switch too long, otherwise the system will go into the COAST mode.

  3. Press and quickly release or tap the SET/CRUISE button switch.

You can press the accelerator at any time in order to accelerate while the cruise system is operating. When you release the accelerator, the vehicle returns to the last set cruise speed.
