To Set Cruise Control

Do not use the cruise control on slippery roads, winding roads or in traffic of heavy or varying volume. When you are traveling down a steeply graded hill, the cruise control should be disengaged by depressing the brake pedal lightly. The transmission can then be shifted into a lower gear range to help control the vehicle speed. Failure to follow these CAUTIONS could possibly cause you to lose control of the vehicle and result in damage to the vehicle and personal injury.

  1. Drive the vehicle above 40 km/h (25 mph).
  2. Depress and release the CRUISE ON OFF button.
  3. Accelerate to the desired speed.
  4. Move the cruise control switch downward to the SET/COAST position and release.
  5. Take your foot off the accelerator pedal.

To Resume a Set Speed

Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, shuts off the cruise control. But you do not need to reset it. Once you're going 40 km/h (25 mph) or more, you can move the cruise control switch upward to the RES/ACC position and release. You will go right back up to your chosen speed and stay there. If you turn the ignition off, or turn cruise switch off, you will erase memory.

To Get Out of Cruise Control

There are three ways to turn off the cruise control.

  1. Step lightly on the brake pedal.
  2. Depress and release the CRUISE ON OFF button.
  3. Depress the clutch pedal (manual transmissions).

Passing Another Vehicle While Using Cruise Control

Use the accelerator pedal to increase your speed. When you take your foot off the pedal, your vehicle will slow down to the cruise control speed you set earlier.

To Increase Speed While Using Cruise Control

There are two ways to gain higher speed while using cruise control.

  1. Use the accelerator pedal to get to the higher speed, move the cruise control switch downward to the SET/COAST position and release. You will now cruise at the higher speed.
  2. Move the cruise switch upward to the RES/ACC position, hold it there until you get up to the speed you want and release. To increase your speed in very small amounts, move the cruise control switch upward to the RES/ACC position for less than 3/4 of a second and release it. Each time you do this, your vehicle will go approximately 1.6 km/h (1 mph) faster.

The accelerate feature will only work after you turn on the cruise control by pushing and releasing the ON OFF button and setting a cruise control speed.

Using Cruise Control on Hills

How well your 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 to maintain your speed. When going downhill, you may have to brake or shift to a lower gear to keep your speed down. Of course, applying the brake takes you out of cruise control. Many drivers find this to be too much trouble and do not use cruise control on steep hills.

To Erase Cruise Speed Memory

When you turn off the cruise control or the ignition is turned off, your cruise control set speed memory is erased.

To Reduce Speed While Using Cruise Control

There are two ways to reduce your speed while using cruise control.

  1. Move the cruise control switch downward to the SET/COAST position and hold until you obtain the lower speed you want. Then release it.
  2. To slow down in very small amounts move the cruise control switch downward to the SET/COAST for less than 3/4 of a second and release. Each time you do this, you will go approximately 1.6 km/h (1 mph) slower.
