The lever located on the left side of the steering column includes the following:

    • Turn and Lane Change Signals
    • Headlamp High/Low-Beam Changer
    • Flash-To-Pass

For information on the exterior lamps, see Exterior Lamps .

Turn and Lane-Change Signals

To signal a turn, move the lever on the left side of the steering wheel all the way up or down. The lever returns automatically when the turn is complete.


Object Number: 808320  Size: A1

An arrow located on the instrument panel cluster will flash in the direction of the turn or lane change.

Raise or lower the lever until the arrow starts to flash to signal a lane change. Hold it there until the lane change is complete. The lever returns when it is released.

If the turn signal is left on, a warning chime will sound and the Driver Information Center (DIC) will display TURN SIGNAL ON after driving about a mile to remind you to turn it off.

Arrows that flash rapidly when signaling for a turn or lane change may be caused by a burned-out signal bulb. Other drivers will not see the turn signal.

Replace burned-out bulbs to help avoid possible accidents. Check the fuse and for burned-out bulbs if the arrow fails to work when signaling a turn. See Fuses and Circuit Breakers .

Headlamp High/Low-Beam Changer

When the low-beam headlamps are on, push the turn signal lever away from you to change the headlamps to high beam.


Object Number: 808597  Size: A1

This light on the instrument panel cluster will be on, indicating high-beam usage.

Pull the turn signal lever toward you to return to low-beam headlamps.

Flash-To-Pass

This feature lets you use the high-beam headlamps to signal the driver in front of you that you want to pass.

Pull the turn signal lever toward you briefly to flash-to-pass. When you do, the following will occur:

    • If the headlamps are either off or in the Daytime Running Lamps (DRL) mode, the high-beam headlamps will turn on. They will stay on as long as you hold the lever there. Release the lever to turn them off.
    • If the headlamps are on low beam, they will remain active and the high beam will also illuminate until you release the lever.

Windshield Wipers


Object Number: 814230  Size: B3

You can control the windshield wipers by moving the lever with the wiper symbol on it. This lever is located on the right side of your steering column. For information on wiper-activated headlamp operation, refer to Exterior Lamps .

The following is a list of the available settings:

LO or HI: Move the lever up to LO for steady wiping at a slow speed. Move the lever higher to HI for steady wiping at a high speed.

INT (Delay): Move the lever up to the INT position, then turn the INT ADJ band, which is located on the lever, to adjust the delay time. The higher you turn the INT ADJ band, the more frequently the wipers will operate.

OFF: Lower the lever to its resting position (OFF) to turn off the wipers.

MIST: Pull the lever down once and release it for a single wipe cycle. For more cycles, hold the lever down in the MIST position longer.

To wash the windshield, press the button located at the tip of the lever.

Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If the blades do become damaged, get new blades or blade inserts.

Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload.

Your vehicle is equipped with wiper-activated headlamps. After the windshield wipers have been on for approximately six seconds, the headlamps will automatically turn on. See Wiper Activated Headlamps under Exterior Lamps for more information.

Rainsense™ II Wipers

Your vehicle may be equipped with Rainsense™ II wipers. The moisture sensor for this feature is mounted on the interior side of the windshield below the rearview mirror and is used to automatically operate the wipers by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on driving conditions and the sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes will occur more frequently. The Rainsense™ wipers operate in a delay mode as well as a continuous low or high speed as needed. If the system is left on for long periods of time, occasional wipes may occur without any moisture on the windshield. This is normal and indicates that the Rainsense™ system is activated.

The Rainsense™ system can be activated by moving the wiper stalk up to the INT position and turning the INT ADJ band to one of the five sensitivity levels. The bottom INT ADJ position is the lowest sensitivity setting, level one. This allows more rain or snow to collect on the windshield between wipes. Turning the INT ADJ band away from you to the higher sensitivity levels allows less rain or snow to collect on the windshield between wipes.

The top position is the highest sensitivity setting, level five. A single wipe will occur each time you turn the INT ADJ band to a higher sensitivity level to indicate that the sensitivity level has been increased.

Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash.

The MIST and "wash" cycles operate as normal and are not affected by the Rainsense™ function. The Rainsense™ system can be overridden at any time by manually changing the wiper control to LO or HI speed.

While Rainsense is active, the headlamps will turn on automatically. The headlamps will turn off again once the wipers turn off if it is light enough outside. If it is dark, they will remain on. See "Wiper-Activated Headlamps" under Exterior Lamps for more information.

Notice: Do not place stickers or other items on the exterior glass surface directly in front of the moisture sensor. Doing this could cause the moisture sensor to malfunction.

Windshield Washer

The windshield washer has both a "demand" mode and a "programmed" mode, depending on the amount of windshield washer fluid you need.

Caution: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision.

To spray washer fluid on the windshield in the programmed mode, press and release the button on the tip of the lever. The washer will provide a measured amount of fluid to the windshield and the wiper will either stop or return to your original wiping speed. To spray washer fluid on the windshield in the demand mode, press and hold the button until you have enough fluid, and the wipers will either stop or return to your original wiping speed.

CHECK WASHER FLUID will be displayed on the Driver Information Center (DIC) when the washer fluid reaches a low level.

Cruise Control

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 is helpful on long trips. Cruise control does not work at speeds below about 25 mph (40 km/h). When cruise control is on, you will see a CRUISE light on the instrument panel cluster.

When you apply your brakes, the cruise control shuts 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) . 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.

Object Number: 808208  Size: A3

The buttons to operate cruise control are located on the steering wheel.

  1. Press CRUISE ON/OFF, located on the bottom left of the steering wheel, to turn cruise control on. An indicator light will come on to show that the cruise control is on.
  2. Get up to the speed you want.
  3. Press SET/CST (coast) located on the bottom right of the steering wheel. The CRUISE light will display on the instrument panel cluster.
  4. Remove your foot from the accelerator pedal.

Resuming a Set Speed

Suppose you set your cruise control at a desired speed and then you apply the brake. This shuts off the cruise control. But you do not need to reset it.

Once the vehicle is traveling approximately 25 mph (40 km/h) or more, you can press RES/ACC (resume/accelerate) to return to your desired preset speed. The CRUISE light will be displayed again.

The vehicle will return to and stay at your preset speed. If you press and hold RES/ACC, the vehicle speed will increase until you release the button or apply the brake. Unless you want to go faster, do not press and hold RES/ACC.

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 SET/CST, then release it and the accelerator pedal. You will now cruise at the higher speed.
    • Press RES/ACC. Hold it there until you get up to the speed that you want, and then release it. To increase your speed in very small amounts, briefly press RES/ACC and then release it. Each time you do this, your vehicle will speed up approximately 1 mph (1.6 km/h) faster.

The accelerate feature will only work after you have set the cruise control speed by pressing SET/CST.

Reducing Speed While Using Cruise Control

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

    • Press SET/CST until you reach the lower speed you want, then release it.
    • To slow down in very small amounts, press SET/CST briefly. Each time you do this, the vehicle will slow down approximately 1 mph (1.6 km/h).

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 or shift to a lower gear to keep your speed down. Applying the brake or shifting into a lower gear will take you out of cruise control. If you need to apply the brake or shift to a lower gear due to the grade of the downhill slope, you may not want to attempt to use your cruise control feature.

Ending Cruise Control

To turn off the cruise control, step lightly on the brake pedal or press CRUISE ON/OFF on the steering wheel.

Erasing Speed Memory

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