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.

(Off): This position turns the system off.

(On): This position activates the system.

+ (Resume/Accelerate): This position to makes the vehicle accelerate or resume to a previously set speed.

(Set): Press this button 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 cruise control is on when the Traction Control System (TCS), if your vehicle has one, begins to limit wheel spin, the cruise control will automatically disengage. See Traction Control System (TCS) . When road conditions allow you to safely use it again, you may 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.

This symbol, along with the CRUISE SET message, will briefly appear in the Driver Information Center (DIC) when the cruise control is set.

The CRUISE SET message will also appear briefly on the Head-Up Display (HUD), if your vehicle has one, when the cruise control lever is pushed to the minus (set) or the plus (resume/accelerate) positions.

A cruise control light will also appear on the instrument panel cluster when the cruise control is on. This light will disappear when the brakes are applied or the cruise control is cancelled. It will reappear when the set cruise speed is resumed. The light will go out when the cruise control is turned off. See Cruise Control Light .

Resuming a Set Speed

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.

Your vehicle will go back up to your previously 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. 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 the vehicle speed in very small amounts, move the switch briefly to resume/accelerate. Each time this is done, the vehicle will go about 1 mph (1.6 km/h) faster.

The acceleration feature will only work after the cruise control speed has been set by pushing the cruise control set button.

Reducing Speed While Using Cruise Control

There are two ways to reduce the vehicle's speed while using cruise control:

    • Press and hold the set button until you reach the lower speed desired, then release it.
    • To slow down in very small amounts, briefly press the set button. Each time this is done, the vehicle will slow down about one mph (1.6 km/h).

Passing Another Vehicle While Using Cruise Control

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

Using Cruise Control on Hills

How well the cruise control will work on hills depends upon the vehicle's speed, its load, and the steepness of the hills. When going up steep hills, the accelerator pedal might have to be used in order to maintain the vehicle's speed. When going downhill, the brakes might have to be applied, or the transmission might have to be shifted to a lower gear to keep the vehicle's speed down. Doing either of these things will take the vehicle out of cruise. It may be better not to use the cruise control if the brakes constantly have to be applied, or the vehicle continuously needs to be shifted to a lower gear.

Ending Cruise Control

There are two ways to turn off the cruise control:

    • Step lightly on the brake pedal.
    • Move the cruise control switch to off.

Erasing Speed Memory

The cruise control set speed memory is erased when the cruise control or the ignition is turned off.
