Your vehicle has cruise control.

(Off):  Slide the switch to this position to turn the system off.

(On): Slide the switch to this position to turn the system on.

(Resume/Accelerate): Slide the switch to this position to make the vehicle accelerate or resume a previously set speed.

(Set): Press this button at the end of the lever to set the speed.

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).

Cruise control will not work if your parking brake is set, or if the master cylinder brake fluid level is low.

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, and has the Traction Control System (TCS), and it begins to limit wheel spin, the cruise control automatically disengages. See Traction Control System (TCS) . When road conditions allow you to safely use it again, you can turn 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 desired.
  3. Press in the set button at the end of the lever and release it.
  4. Take your foot off the accelerator pedal.

When the cruise control is engaged, the CRUISE SET TO XX MPH message displays on the Driver Information Center (DIC). See Other Messages .

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 do not need to reset it.

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

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

If you hold the switch at resume/accelerate the vehicle keeps going faster until you release the switch or apply the brake. Do not hold the switch at resume/accelerate, unless you want the vehicle to go faster.

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 will now cruise at the higher speed. If the accelerator pedal is held longer than 60 seconds, cruise control will turn off.
    • Move the cruise switch from on to resume/accelerate. Hold it there until you get up to the speed desired, 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.

Reducing Speed While Using Cruise Control

    • Press and hold the set button 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 will 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 slows 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 might want to step on the accelerator pedal to maintain the vehicle's speed. When going downhill, you might have to brake or shift to a lower gear to keep the vehicle's speed down. Of course, applying the brake turns off the cruise control. Many drivers find this to be too much trouble and do not use cruise control on steep hills.

Cruise Control in Sport (S) and Manual Paddle Shift Gear Selection

When your vehicle is in Sport (S) and the manual paddle shift controls are not being used, cruise control operates in the same manner as Drive (D).

When your vehicle is in Sport (S) and the manual paddle shift controls are being used, cruise control operates as follows:

    • If cruise control is active and a gear is selected with the manual paddle shift controls, the vehicle maintains vehicle speed in the driver selected gear and will not automatically up-shift or down-shift the transmission while the driver’s gear selection is active.
    •  If driving in hilly terrain, cruise control may not be able to maintain vehicle speed if an up-shift or down-shift is not selected by the driver. While driving on hilly terrain and cruise control is active with a manual paddle shift gear selection, the driver must select the proper gear for the terrain or select Drive (D) on the gear range selector for full automatic transmission operation.

Ending Cruise Control

To end a cruise control session, step lightly on the brake pedal. If your vehicle has a manual transmission, lightly tapping the clutch will also end a cruise control session.

Move the cruise control switch to off to turn the system completely off.

When cruise control is disengaged, the CRUISE DISENGAGED message displays on the Driver Information Center (DIC). See DIC Warnings and Messages .

Erasing Speed Memory

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