Set Cruise Control

Caution: Do not use the cruise control on slippery roads, steeply graded roads, or in heavy traffic of heavy or varying volume. Failure to follow these CAUTIONS could possibly cause you to loose control of the vehicle and result in damage to the vehicle and personal injury.

  1. Push the cruise control ON/OFF switch to ON.
  2. Accelerate to the desired speed.
  3. Push in the SET button, and release the button.
  4. Remove your foot from the accelerator pedal.

Resume a Set Speed

Once the cruise control has been set at a desired speed with the SET button, the set speed is stored in the controllers memory. If the driver for any reason must apply the brake, the cruise control will disengage. The cruise control may be reset in the following manner:

  1. Accelerate close to the desired speed 40 km/h (25 mph), or more.
  2. Press the cruise control R/A switch (Resume/Accelerate) for about half a second.

The vehicle will now accelerate to and resume the previously set speed. If either the ignition switch, or the cruise ON/OFF switch is turned off, you will erase the cruise control memory.

Reduce Speed While Using Cruise Control

In order to reduce your speed while using the cruise control, perform one of the following steps:

  1. Push in and hold the SET button until you reach the lower speed you want, then release the button.
  2. In order to slow down incrementally, push the set button for less than half a second. Each time you do this, the vehicle will slow down 1.6 km/h (1 mph).

Increase Speed While Using Cruise Control

In order to increase speed while using the cruise control, perform one of the following steps:

  1. Accelerate to the higher speed, push the SET button, then release the button and the accelerator pedal. The cruise control will now maintain that higher set speed.
  2. Once a set speed has been chosen, the driver can press the cruise switch R/A, and hold the switch there until the new speed setting is reached, then release the switch. In order to increase your speed incrementally, press the R/A switch for less than half a second, then release the switch. Each time you do this, the vehicle will maintain a speed that is 1.6 km/h (1 mph) faster.

The accelerate feature will only work after you turn on the cruise control and push the SET button.

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal in order to increase your speed. Once the vehicle is a safe distance past the other vehicle, take your foot off of the accelerator pedal. The vehicle will then return to the preset cruise control speed.

Using Cruise Control on Hills

How well the cruise control will work on hills depends upon your speed, load, and the incline of the hills. When going up steep hills, you may have to step on the accelerator pedal in order to maintain your speed. When going downhill, you may have to shift to a lower gear or brake in order to keep your speed down. Applying the brake will take you out of cruise control. Many drivers find this to be too much trouble and choose not to use the cruise control on steep hills.

Erase Cruise Speed Memory

When you turn off the ignition, or the cruise control ON/OFF switch is turned off, the cruise control set speed memory is erased.

Disengage Cruise Control

Turn off the cruise control using one of the following steps:

  1. Step lightly on the brake pedal.
  2. Move the cruise switch to OFF.
