The lever 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 exterior lamps, see "Exterior Lamps" later in this section.

Turn and Lane-Change Signals

The turn signal has two upward (for right) and two downward (for left) positions. These positions allow you to signal either a turn or a lane change.

To signal a turn, move the lever all the way up or down. When the turn is finished, the lever will return automatically.


Object Number: 807334  Size: A1

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

To signal a lane change, just raise or lower the lever until the arrow starts to flash. Hold it there until you complete your lane change. The lever will return by itself when you release it.

As you signal a turn or a lane change, if the arrows flash very fast, a bulb may be burned out and other drivers won't see your turn signal.

If a bulb is burned out, replace it to help avoid an accident.

If the arrows don't go on at all when you signal a turn, check the fuse (see Fuses and Circuit Breakers ) and check for burned-out bulbs.

Turn Signal On Chime

If your turn signal is left on for more than 0.8 miles (1.3 km), a chime will sound at each flash of the turn signal and the DIC will display the TURN SIGNAL ON? reminder message. To turn off the chime and message, move the turn signal lever to the off position. To turn off the DIC message while the turn signal is still active, press any button on the DIC. See Driver Information Center (DIC) for more information.

Headlamp High/Low-Beam Changer

To change the headlamps from low beam to high, push the lever away from you until you hear a click. Then release it.


Object Number: 808597  Size: A1

When the high beams are on, this light on the instrument panel cluster will also be on.

If the fog lamps are on when you turn on the high-beam headlamps, the fog lamps will turn off. The fog lamps will turn back on when you turn off the high-beam headlamps.

Flash-to-Pass

This feature lets you use your high-beam headlamps to signal a driver in front of you that you want to pass. It works even if your headlamps are off.

To use it, pull the turn signal lever toward you.

Your high-beam headlamps will turn on. They'll stay on as long as you hold the lever there. Release the lever to turn them off.

If your headlamps are on, and on high beam, your headlamps will switch to low beam when the lever is released. To get back to high beam, push the lever away from you.

Windshield Wipers


Object Number: 814230  Size: B3

The lever on the right side of your steering column operates your windshield wipers.

If your windshield wipers are on for more than six seconds while you are driving, the low-beam headlamps, instrument panel cluster backlighting and the taillamps will turn on. For more information see "Wiper-Activated Headlamps" under Exterior Lamps .

For a single wiping cycle, move the lever down to MIST. Hold it there until the wipers start, then release it. The wipers will stop after one cycle. If you want more cycles, hold the lever on MIST longer.

For steady wiping at low speed, move the lever up to the LO position. For high-speed wiping, move the lever up further, to HI. To stop the wipers, move the lever to OFF.

You can set the wiper speed for a long or short delay between wiper cycles. Move the lever up to the first detent, INT (Intermittent). Turn the band labeled INT ADJ (Intermittent Adjustment) down toward the shorter lines for fewer wiper passes per minute. As you turn the band toward the longer lines, the wiper cycles per minute will increase.

Remember that damaged wiper blades may prevent you from seeing well enough to drive safely. To avoid damage, be sure to clear ice and snow from the wiper blades before using them. If they're frozen to the windshield, carefully loosen or thaw them. If your blades do become damaged, get new blades or blade inserts. See Windshield Wiper Blade Replacement .

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

Rainsense™ II Wipers

The moisture sensor is mounted on the interior side of the windshield below the rearview mirror and is used to automatically operate the windshield wipers. This system operates by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on the driving conditions and sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes will occur more frequently. The system will operate in the delay, low speed and high speed modes. 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 is activated by moving the wiper lever up to the INT position and turning the INT ADJ band to one of the five sensitivity levels within the delay area. 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. You can increase the sensitivity of the system and the frequency of wipes by turning the INT ADJ band away from you to the higher sensitivity levels. 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 system can be overridden at any time by manually changing the wiper control to LO or HI speed.

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

Windshield Washer

The lever on the right side of your steering column also controls your windshield washer. To spray washer fluid on the windshield, push the button on the end of the lever. The wipers will clear the window and then either stop or return to your preset speed. For more washer cycles, push and hold the button.

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.

Ice build up can block washer nozzles. Remove ice for proper operation.

If the fluid level in the windshield washer bottle is low, the message LOW WASHER FLUID will appear on the DIC. See Windshield Washer Fluid .

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 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: 822614  Size: B3
  1. Push the cruise control switch, located on the right side of the steering column at the end of the lever, in to ON.
  2. Get up to the speed you want.
  3. Push the lever down to SET-CST (Coast) and release it. The CRUISE light on the instrument panel cluster will come on.
  4. Take your foot off the accelerator pedal.

Resuming a Set Speed

Setting the cruise control at a desired speed and then applying the brake will end the cruise control function.

Once you're going about 25 mph (40 km/h) or more, you can briefly push the cruise control lever up to RES-ACC (Resume-Accelerate) to reset. This returns you to the desired preset speed.

Remember, if you hold the lever up at RES-ACC, the vehicle will accelerate until you release the lever or apply the brake. So unless you want to go faster, don't hold the lever at RES-ACC.

Increasing Speed While Using Cruise Control

There are three ways to go to a higher speed:

    • Use the accelerator pedal to go to a higher speed. Push the lever down, then release the lever and the accelerator pedal. You'll now cruise at the higher speed.
    • Move the cruise lever up to RES-ACC. Hold it there until you reach a desired speed and then release the lever.
    • To increase your speed in very small amounts, move the lever up to RES-ACC briefly and then release it. Each time you do this, your vehicle will go about 1 mph (1.6 km/h) faster.

The accelerate feature will only work after you have set the cruise control speed by pushing the lever down to SET-CST.

Reducing Speed While Using Cruise Control

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

    • Push the lever down until you reach a desired lower speed then release it.
    • To slow down in very small amounts, push the lever down briefly. 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 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 don't use cruise control on steep hills.

Ending Cruise Control Without Erasing the Set Speed

There are two ways to turn off the cruise control:

    • Step lightly on the brake pedal, or
    • pull the cruise lever towards you to cancel cruise.

To resume the set speed see "Resuming a Set Speed" earlier in this section.

Erasing Speed Memory

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