These controls are located on the end of the multifunction lever.

(Off): This position turns the system off.

(On): This position activates the system.

+ (Resume/Accelerate): Push the lever to this symbol to make the vehicle resume to a previously set speed or to accelerate when cruise is already active.

(Set/Decrease): Press this button to set the speed or to decrease the speed when cruise is already active.

With cruise control, you can maintain a speed of about 25 mph (40 km/h) or more without keeping your foot on the accelerator. This can really help on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h).

If you apply your brakes, the cruise control will shut off.

Caution: Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic.

Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

If your vehicle is in cruise control when the traction control system begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control System (TCS) and StabiliTrak® System . When road conditions allow you to safely use it again, you may turn the cruise control back on.

Setting Cruise Control

Caution: If you leave your cruise control on when you are not using cruise, you might hit a button and go into cruise when you do not want to. You could be startled and even lose control. Keep the cruise control switch off until you want to use cruise control.

  1. Move the cruise control switch to on.
  2. Get up to the speed you want.
  3. Press in the set button at the end of the lever and release it.
  4. Take your foot off the accelerator pedal.

This light on the instrument panel cluster will come on while cruise control is on.

Resuming a Set Speed

Suppose you set your cruise control at a desired speed and then you apply the brake. This, of course, disengages the cruise control. But you don't need to reset it.

Once you're going about 25 mph (40 km/h) or more, you can move the cruise control switch briefly from on to resume/accelerate.

You'll go right back up to your chosen speed and stay there.

If you hold the switch at resume/accelerate the vehicle will keep going faster until you release the switch or apply the brake. So unless you want to go faster, don't hold the switch at resume/accelerate.

Increasing Speed While Using Cruise Control

There are two ways to go to a higher speed:

    • Use the accelerator pedal to get to the higher speed. Press the set button at the end of the lever, then release the button and the accelerator pedal. You'll now cruise at the higher speed.
    • Move the cruise switch from on to resume/accelerate. Hold it there until you get up to the speed you want, and then release the switch. To increase your speed in very small amounts, move the switch briefly to resume/accelerate. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.

If using the accelerator pedal and the set button at end of the lever to increase cruise set speed, your new set speed must be at least 10 mph higher than current speed for this method to work. If it is not 10 mph higher, switch cruise switch off, then on, and then reset your speed using the set button.

Reducing Speed While Using Cruise Control

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

    • Press in the button at the end of the lever until you reach the lower speed you want, then release it.
    • To slow down in very small amounts, briefly press the set button. Each time you do this, you'll go about 1 mph (1.6 km/h) slower.

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.

Using Cruise Control on Hills

How well your cruise control will work on hills depends upon your speed, load and the steepness 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 to keep your speed down. Applying the brake will take you out of cruise control. If you need to apply the brake due to the grade of the downhill slope, you may not want to attempt to use your cruise control feature.

Ending Cruise Control

To end a cruise control session, step lightly on the brake pedal.

Stepping on the brake pedal will end the current cruise control session only. Move the cruise control switch to off to turn off the system completely.

Erasing Speed Memory

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