Shifting out of Park

Automatic Transmission Shift Lock The vehicle has an automatic transmission shift lock control system. The shift lock control system is designed to: . Prevent ignition key removal

unless the shift lever is in P (Park).

. Prevent movement of the shift

lever out of P (Park), unless the ignition is in ON/RUN and the brake pedal is applied.

The shift lock is always functional except in the case of an uncharged or low voltage (less than 9‐volt) battery.

If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Starting (On-board with eAssist Only) on page 10-78 or Jump Starting (with or without eAssist) on page 10-79. If the shift lever cannot be moved out of P (Park): 1. Apply and maintain the regular

brakes.

2. Turn the ignition to the ON/RUN position. See Ignition Positions (Key Access) on page 9-15 or Ignition Positions (Keyless Access) on page 9-16 for more information.

3. Let up on the shift lever and make sure the shift lever is pushed all the way into P (Park).

4. Press the shift lever button. 5. Move the shift lever into the

desired gear.

Engine Exhaust { Warning

Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if:

. The vehicle idles in areas

with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes).

. The exhaust smells or

sounds strange or different.

. The exhaust system leaks

due to corrosion or damage. . The vehicle exhaust system

has been modified, damaged, or improperly repaired.

(Continued)

Warning (Continued)

. There are holes or openings

in the vehicle body from damage or aftermarket modifications that are not completely sealed.

If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle:

. Drive it only with the windows

completely down.

. Have the vehicle repaired

immediately.

Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation.

Running the Vehicle While Parked It is better not to park with the engine running. If the vehicle is left with the engine running, follow the proper steps to be sure the vehicle will not move. See Shifting Into Park on page 9-24
and Engine Exhaust on page 9-26. If parking on a hill and pulling a trailer, see Driving Characteristics and Towing Tips on page 9-63.

Driver Shift Control (DSC)

{ Caution

Driving with the engine at a high rpm without upshifting while using Driver Shift Control (DSC), could damage the vehicle. Always upshift when necessary while using DSC.

DSC allows the automatic transmission to be shifted similar to a manual transmission. To use the DSC feature:

With Selective Ride Control 1. Move the shift lever from

D (Drive) to M/S (Manual Mode/ Sport Mode). The vehicle will be in Sport Mode. The vehicle will remain in Sport Mode until the shift lever is moved back to the D (Drive)

position. The gear indicator in the instrument cluster will still display an S for Sport Mode, and the SPORT MODE ON message will display momentarily. See Ride Control System Messages on page 5-42. When in Sport Mode, the vehicle will still shift automatically, but chassis tuning is modified. See Selective Ride Control on page 9-36. If you press the +/− switch on the side of the shift lever, the transmission will enter Manual Mode, and the DIC gear indicator will change to an M followed by a number representing the gear the vehicle is currently in. In Manual Mode, press the + (Plus) end of the switch on the side of the shift lever to upshift, or the − (Minus) end to downshift.

Without Selective Ride Control 1. Move the shift lever from

D (Drive) to M (Manual Mode). The transmission will enter Manual Mode. The DIC gear indicator will change to an M followed by a number representing the gear the vehicle is currently in. In Manual Mode, press the + (Plus) end of the switch on the side of the shift lever to upshift, or the − (Minus) end to downshift.

2.

The display on the instrument cluster will show which gear the vehicle is in. The number indicates the requested gear when pressing the +/− switch on the shift lever. The transmission will only allow shifting into gears appropriate for the vehicle speed and engine revolutions per minute (rpm). The transmission will not automatically shift to the next lower gear if the

Driving and Operating

engine rpm is too high, nor to the next higher gear when the maximum engine rpm is reached. While in Manual Mode, the transmission will automatically downshift when the vehicle comes to a stop. This will allow for more power during take-off. When accelerating the vehicle from a stop in snowy and icy conditions, you may want to shift into 2 (Second) gear. A higher gear allows the vehicle to gain more traction on slippery surfaces.

Drive Systems

Brakes

All-Wheel Drive Vehicles with this feature always send engine power to all four wheels. It is fully automatic, and adjusts itself as needed for road conditions. All-Wheel Drive (AWD) system performance will be automatically reduced when the compact spare tire is in use. To restore full AWD performance, and prevent excessive wear to the AWD system, replace the compact spare tire with a full-size tire as soon as possible. See Compact Spare Tire on page 10-77.

Antilock Brake System (ABS) This vehicle has ABS, an advanced electronic braking system that helps prevent a braking skid. When the vehicle begins to drive away, ABS checks itself. A momentary motor or clicking noise might be heard while this test is going on, and it might even be noticed that the brake pedal moves a little. This is normal.

If there is a problem with ABS, this warning light stays on. See Antilock Brake System (ABS) Warning Light on page 5-20.

Buick LaCrosse Owner Manual 7707475) - 2015 - CRC - 10/9/14

suddenly slows or stops. Always leave enough room up ahead to stop, even with ABS. Using ABS Do not pump the brakes. Just hold the brake pedal down firmly and let ABS work. You may hear the ABS pump or motor operating and feel the brake pedal pulsate. This is normal. Braking in Emergencies ABS allows you to steer and brake at the same time. In many emergencies, steering can help more than even the very best braking.

If driving safely on a wet road and it becomes necessary to slam on the brakes and continue braking to avoid a sudden obstacle, a computer senses the wheels are slowing down. If one of the wheels is about to stop rolling, the computer will separately work the brakes at each wheel. ABS can change the brake pressure to each wheel, as required, faster than any driver could. This can help you steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you, there will not be enough time to apply the brakes if that vehicle

Parking Brake

The Electric Parking Brake (EPB) switch is on the center console. The EPB can always be activated, even if the ignition is off. To prevent draining the battery, avoid repeated cycles of the EPB when the engine is not running. The system has a red parking brake status light and an amber parking brake warning light. See Electric Parking Brake Light on page 5-20
and Service Electric Parking Brake Light on page 5-20. There are also

parking brake-related Driver Information Center (DIC) messages. See Brake System Messages on page 5-36. In case of insufficient electrical power, the EPB cannot be applied or released. Before leaving the vehicle, check the red parking brake status light to ensure that the parking brake is applied. EPB Apply To apply the EPB: 1. Be sure the vehicle is at a

complete stop.

2. Lift up the EPB switch

momentarily.

The red parking brake status light will flash and then stay on once the EPB is fully applied. If the red parking brake status light flashes continuously, then the EPB is only partially applied or there is a problem with the EPB. A DIC message will display. Release the EPB and try to apply it again. If the light does not come on, or keeps

flashing, have the vehicle serviced. Do not drive the vehicle if the red parking brake status light is flashing. See your dealer. See Electric Parking Brake Light on page 5-20. If the amber parking brake warning light is on, lift up on the EPB switch and hold it up. Continue to hold the switch until the red parking brake status light remains on. If the amber parking brake warning light is on, see your dealer. If the EPB is applied while the vehicle is moving, the vehicle will decelerate as long as the switch is held up. If the switch is held up until the vehicle comes to a stop, the EPB will remain applied. The vehicle may automatically apply the EPB in some situations when the vehicle is not moving. This is normal, and is done to periodically check the correct operation of the EPB system. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement.

EPB Release To release the EPB: 1. Place the ignition in the ACC/

ACCESSORY or ON/RUN position.

2. Apply and hold the brake pedal. 3. Push down momentarily on the

EPB switch.

The EPB is released when the red parking brake status light is off. If the amber parking brake warning light is on, release the EPB by pushing down on the EPB switch and holding it down. Continue to hold the switch until the red parking brake status light is off. If either light stays on after release is attempted, see your dealer.

Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve parking brake lining life. If parking on a hill, or if the vehicle is pulling a trailer, see Driving Characteristics and Towing Tips on page 9-63.

Driving and Operating

9-33

Brake Assist The Brake Assist feature is designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The Brake Assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.

Hill Start Assist (HSA) This vehicle has an HSA feature, which may be useful when the vehicle is stopped on a grade sufficient enough to activate HSA. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. After the driver completely stops and holds the vehicle in a complete standstill on a grade, HSA will be automatically activated. During the transition period between when the driver releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds the braking pressure for a maximum of two seconds to ensure that there is no rolling. The brakes will automatically release when the accelerator pedal is applied within the two-second window. It will not activate if the vehicle is in a drive gear and facing downhill, or if the vehicle is facing uphill and in R (Reverse).

Driving and Operating

Ride Control Systems

Traction Control/ Electronic Stability Control

System Operation The vehicle has a Traction Control System (TCS) and StabiliTrak®, an electronic stability control system. These systems help limit wheel slip and assist the driver in maintaining control, especially on slippery road conditions. TCS activates if it senses that any of the drive wheels are spinning or beginning to lose traction. When this happens, TCS applies the brakes to the spinning wheels and reduces engine power to limit wheel spin. StabiliTrak activates when the vehicle senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure to any one of the

vehicle wheel brakes to assist the driver in keeping the vehicle on the intended path. If cruise control is being used and traction control or StabiliTrak begins to limit wheel spin, cruise control will disengage. Cruise control may be turned back on when road conditions allow. Both systems come on automatically when the vehicle is started and begins to move. The systems may be heard or felt while they are operating or while performing diagnostic checks. This is normal and does not mean there is a problem with the vehicle. It is recommended to leave both systems on for normal driving conditions, but it may be necessary to turn TCS off if the vehicle gets stuck in sand, mud, ice, or snow. See If the Vehicle Is Stuck on page 9-9 and “Turning the Systems Off and On” later in this section.

The indicator light for both systems is in the instrument cluster. This light will:

Flash when TCS is limiting wheel spin. Flash when StabiliTrak is activated. Turn on and stay on when either system is not working.

If either system fails to turn on or to activate, a message displays in the Driver Information Center (DIC), and d comes on and stays on to indicate that the system is inactive and is not assisting the driver in maintaining control. The vehicle is safe to drive, but driving should be adjusted accordingly.

3. Start the engine. Drive the vehicle. If d comes on and stays on, the vehicle may need more time to diagnose the problem. If the condition persists, see your dealer.

The TCS/StabiliTrak button is on the center console.

{ Caution

Do not repeatedly brake or accelerate heavily when TCS is off. The vehicle driveline could be damaged.

To turn off only TCS, press and release the g button. The traction off light i displays in the instrument cluster. The appropriate DIC message displays. See Ride Control System Messages on page 5-42. To turn TCS on again, press and release the g button. The traction off light i displayed in the instrument cluster will turn off. If TCS is limiting wheel spin when the g button is pressed, the system will not turn off until the wheels stop spinning. To turn off both TCS and StabiliTrak, press and hold the g button until the traction off light i and StabiliTrak OFF light g come on and stay on in the instrument cluster. The appropriate DIC message displays. See Ride Control System Messages on page 5-42.

Limited-Slip Differential Vehicles with a limited-slip differential can give more traction on snow, mud, ice, sand, or gravel. It works like a standard differential most of the time, but when traction is low, this feature allows the drive wheel with the most traction to move the vehicle.

Selective Ride Control The vehicle may have a ride control system called Selective Ride Control. The system provides the following performance benefits: . Reduced Impact Harshness

Improved Road Isolation Improved High-Speed Stability Improved Handling Response

. Better Control of Body Ride

Motions

To switch from TOUR to SPORT mode, move the shift lever to the M/S (Manual/Sport) position.

TOUR: Use for normal city and highway driving. This setting provides a smooth, soft ride. SPORT: Use where road conditions or personal preference demand more control. This setting provides more “feel,” or response to road conditions through increased steering effort and suspension tuning. The setting can be changed at any time. Based on road conditions, steering wheel angle, and vehicle speed, the system automatically adjusts to provide the best handling while providing a smooth ride. The TOUR and SPORT modes will feel similar on a smooth road.

Cruise Control With cruise control the vehicle can maintain a speed of about 40 km/h (25 mph) or more without keeping your foot on the accelerator. Cruise control does not work at speeds below 40 km/h (25 mph). { Warning

Cruise control can be dangerous where you cannot drive safely at a steady speed. Do not use 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 equipped with the Traction Control System (TCS), the system may begin to limit wheel spin while you are using cruise control. If this happens, the cruise control will automatically disengage. See Traction Control/Electronic Stability Control on page 9-34. If a collision alert occurs when cruise control is activated, cruise control is disengaged. See Forward Collision Alert (FCA) System on page 9-50. When road conditions allow you to safely use it again, cruise control can be turned back on. If the brakes are applied, cruise control disengages.

5 (On/Off): Press to turn cruise control on or off. A white indicator comes on in the instrument cluster. RES+ (Resume/Accelerate): If there is a set speed in memory, press the control up briefly to resume to that speed or press and hold to accelerate. If cruise control is already active, use to increase vehicle speed.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster on page 5-8. The increment value used depends on the units displayed.

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase the vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the previously set cruise speed. While pressing the accelerator pedal or shortly following the release to override cruise control, briefly pressing SET− will result in cruise set to the current vehicle speed.

Using Cruise Control on Hills How well the cruise control will work on hills depends upon the vehicle speed, load, and the steepness of the hills. When going up steep hills, you might have to step on the accelerator pedal to maintain your speed. When going downhill, you might have to brake or shift to a

lower gear to keep your speed down. If the brake pedal is applied, cruise control will disengage.

Ending Cruise Control There are four ways to end cruise control: . Step lightly on the brake pedal. . Press *. . Shift the transmission to

N (Neutral). To turn off cruise control, press 5.

Erasing Speed Memory The cruise control set speed is erased from memory if 5 is pressed or the ignition is turned off.

Adaptive Cruise Control If equipped with Adaptive Cruise Control (ACC), it allows the driver to select the cruise control set speed and following gap. Read this entire section before using this system.

The following gap is the following time between your vehicle and a vehicle detected directly ahead in your path, moving in the same direction. If no vehicle is detected in your path, ACC works like regular cruise control. ACC uses a radar sensor. See Radio Frequency Statement on page 13-12. If a vehicle is detected in your path, ACC can apply acceleration or limited, moderate braking to maintain the selected following gap. To disengage ACC, apply the brake. If ACC is controlling your vehicle speed when the traction control system (TCS) or electronic stability control system activates, the ACC may automatically disengage. See Traction Control/Electronic Stability Control on page 9-34. When road conditions allow ACC to be safely used, the ACC can be turned back on. ACC will not engage if the TCS or electronic stability control system is disabled.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster on page 5-8. The increment value used depends on the units displayed.

Selecting the Follow Distance Gap When a slower moving vehicle is detected ahead within the selected following gap, ACC will adjust the vehicle's speed and attempt to maintain the follow distance gap selected. Press 3 on the steering wheel to adjust the following gap. Each press cycles the gap button through three settings: Far, Medium, or Near. When pressed, the current gap setting displays briefly on the instrument cluster and HUD. The gap setting will be maintained until it is changed. Since each gap setting corresponds to a following time (Far, Medium, or Near), the following distance will vary based on vehicle speed. The faster the vehicle speed, the further back your vehicle will follow a vehicle detected ahead. Consider traffic and weather conditions when selecting the following gap. The

Alerting the Driver

Alert Seat will pulse five times. See “Collision/Detection Systems” under Vehicle Personalization on page 5-45. See Defensive Driving on page 9-3.

Approaching and Following a Vehicle

If ACC is engaged, driver action may be required when ACC cannot apply sufficient braking because of approaching a vehicle too rapidly. When this condition occurs, the collision alert symbol on the HUD will flash on the windshield. Either eight beeps will sound from the front, or both sides of the Safety

The vehicle ahead symbol is in the instrument cluster and HUD display. The vehicle ahead symbol only displays when a vehicle is detected in your vehicle’s path moving in the same direction. If this symbol is not displaying, ACC will not respond to or brake to vehicles ahead. ACC automatically slows the vehicle down and adjusts vehicle speed to follow the vehicle in front at the

selected follow gap. The vehicle speed increases or decreases to follow the vehicle in front of you, but will not exceed the set speed. It may apply limited braking, if necessary. When braking is active, the brake lights will come on. The automatic braking may feel or sound different than if the brakes were applied manually. This is normal.

Stationary or Very Slow-Moving Objects

{ Warning

Adaptive Cruise Control (ACC) may not detect and react to stopped or slow-moving vehicles ahead of you. For example, the system may not brake for a vehicle it has never detected moving. This can occur in stop-and-go traffic or when a vehicle suddenly appears due to a vehicle ahead changing lanes. Your vehicle may not stop and

ACC Automatically Disengages ACC may automatically disengage and the driver will need to manually apply the brakes to slow the vehicle when:

The sensors are blocked. The traction control system (TCS) or electronic stability control system has activated or been disabled.

. No traffic or other objects are

being detected. There is a fault in the system. A message will appear on the DIC indicating that cruise is disengaging.

The ACC active symbol will not be displayed when ACC is no longer active.

Notification to Resume ACC ACC will maintain a follow gap behind a detected vehicle and slow your vehicle to a stop behind that vehicle. If the stopped vehicle ahead has driven away and ACC has not resumed, the vehicle ahead symbol will flash as a reminder to check traffic ahead before proceeding. In addition, the left and right sides of the Safety Alert Seat will pulse three times, or three beeps will sound. See ”Alert Type” and “Go Notifier” in “Collision/Detection Systems” under Vehicle Personalization on page 5-45. When the vehicle ahead drives away, press RES+ or the accelerator pedal to resume cruise control. If stopped for more than two minutes or if the driver door is opened and the driver safety belt is unbuckled, the ACC automatically

applies the electric parking brake to hold the vehicle. The electric parking brake status light will turn on. See Parking Brake on page 9-31. To resume ACC and release the electric parking brake, press the accelerator pedal. A DIC warning message may display indicating to shift to P (Park) before exiting the vehicle. See Vehicle Messages on page 5-35.

{ Warning

If ACC has stopped the vehicle, and if ACC is disengaged, turned off, or canceled, the vehicle will no longer be held at a stop. The vehicle can move. When ACC is holding the vehicle at a stop, always be prepared to manually apply the brakes.

Leaving the vehicle without placing it in P (Park) can be dangerous. Do not leave the vehicle while it is being held at a stop by ACC. Always place the vehicle in P (Park) and turn off the ignition before leaving the vehicle.

ACC Override If using the accelerator pedal while ACC is active, a DIC warning message will indicate that automatic braking will not occur. See Vehicle Messages on page 5-35. ACC will resume operation when the accelerator pedal is not being pressed.

The ACC will not automatically apply the brakes if your foot is resting on the accelerator pedal. You could crash into a vehicle ahead of you.

Curves in the Road

{ Warning

On curves, ACC may not detect a vehicle ahead in your lane. You could be startled if the vehicle accelerates up to the set speed, especially when following a vehicle exiting or entering exit ramps. You could lose control of the vehicle or crash. Do not use ACC while driving on an entrance or exit ramp. Always be ready to use the brakes if necessary.

On curves, ACC may respond to a vehicle in another lane, or may not have time to react to a vehicle in your lane. You could crash into a vehicle ahead of you, or lose control of your vehicle. Give extra attention in curves and be ready to use the brakes if necessary. Select an appropriate speed while driving in curves.

ACC may operate differently in a sharp curve. It may reduce the vehicle speed if the curve is too sharp.

When following a vehicle and entering a curve, ACC may not detect the vehicle ahead and accelerate to the set speed. When this happens, the vehicle ahead symbol will not appear.

Other Vehicle Lane Changes

Do Not Use ACC on Hills and When Towing a Trailer

ACC will not detect a vehicle ahead until it is completely in the lane. The brakes may need to be manually applied.

Do not use ACC when driving on steep hills or when towing a trailer. ACC will not detect a vehicle in the lane while driving on steep hills. The driver will often need to take over acceleration and braking on steep hills, especially when towing a trailer. If the brakes are applied, the ACC disengages.

ACC may detect a vehicle that is not in your lane and apply the brakes. ACC may occasionally provide an alert and/or braking that is considered unnecessary. It could respond to vehicles in different lanes, signs, guardrails, and other stationary objects when entering or exiting a curve. This is normal operation. The vehicle does not need service.

Audible or Safety Alert Seat Some driver assistance features alert the driver of obstacles by beeping. To change the volume of the warning chime, see “Comfort and Convenience” under Vehicle Personalization on page 5-45. If equipped with the Safety Alert Seat, the driver seat cushion may provide a vibrating pulse alert instead of beeping. To change this, see “Collision/Detection Systems” under Vehicle Personalization on page 5-45.

Assistance Systems for Parking or Backing When the vehicle is in R (Reverse), the Rear Vision Camera (RVC) and Rear Parking Assist may help the driver to avoid a crash or to reduce crash damage while parking or backing. Some models may also have the Rear Cross Traffic Alert (RCTA) feature.

When the vehicle is shifted into R (Reverse), the RVC displays an image of the area behind the vehicle in the center stack display. When the vehicle is shifted out of R (Reverse), the screen returns to the previous content, after a short delay. To return to this previous screen sooner, press one of the radio buttons. If the message Service Rear Camera System is displayed, the vehicle may need service.

{ Warning

The RVC system does not display children, pedestrians, bicyclists, crossing traffic, animals, or any other object located outside the camera's field of view, below the bumper, or under the vehicle. Perceived distances may be different from actual distances. Do not back the vehicle using only the RVC screen. Failure to

These detection distances may be shorter during warmer or humid weather. Blocked sensors will not detect objects and can also cause false detections. Keep the sensors clean of mud, dirt, snow, ice, and slush; and clean sensors after a car wash in freezing temperatures.

{ Warning

The parking assist system does not detect children, pedestrians, bicyclists, animals, or objects located below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with parking assist, always check the area around the vehicle and check all mirrors before moving forward or backing.

On vehicles with the Rear Cross Traffic Alert (RCTA), a triangle with an arrow may also display on the RVC screen to warn of traffic coming from either direction when backing. This system detects objects coming from up to 20 m (66 ft) from the left or right side behind the vehicle. When an object is detected, either three beeps sound from the left or right side or three Safety Alert Seat pulses occur on the left or right side, depending on the direction of the detected vehicle. Use caution while backing up when towing a trailer, as the RCTA detection zones that extend out from the back of the vehicle do not move further back when a trailer is towed. With RPA, as the vehicle backs up at speeds of less than 8 km/h (5 mph), the sensors on the rear bumper detect objects up to 2.5 m (8 ft) behind the vehicle that are within a zone 25 cm (10 in) high off the ground and below bumper level.

Turning the Features On or Off

The vehicle may have instrument cluster parking assist display with bars that show “distance to object” and object location information for RPA. As the object gets closer, more bars light up and the bars change color from yellow to amber to red. When an object is first detected, one beep will be heard from the rear, or both sides of the Safety Alert Seat will pulse two times. When an object is very close (<0.6 m (2 ft)), five beeps will sound, or both sides of the Safety Alert Seat will pulse five times.

The X button on the center stack is used to turn on or off the Rear Parking Assist. The indicator light next to the button comes on when the feature is on and turns off when the feature has been disabled. Turn off parking assist when towing a trailer.

Assistance Systems for Driving If equipped, when driving the vehicle forward, Forward Collision Alert (FCA), Lane Departure Warning (LDW), Side Blind Zone Alert (SBZA), Lane Change Alert (LCA), and/or the Active Emergency Braking System can help to avoid a crash or reduce crash damage.

Forward Collision Alert (FCA) System The FCA system may help to avoid or reduce the harm caused by front-end crashes. FCA provides a flashing red alert on the windshield, and beeps or pulses the Safety Alert Seat when approaching a vehicle directly ahead too quickly. FCA also provides a visual alert if following another vehicle much too closely.

{ Warning

FCA does not provide a warning to help avoid a crash, unless it detects a vehicle. FCA may not detect a vehicle ahead if the FCA sensor is blocked by dirt, snow, or ice, or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition. Keep the windshield, headlamps, and FCA sensors clean and in good repair.

FCA detects vehicles within a distance of approximately 60 m (197 ft) and operates at speeds above 40 km/h (25 mph). If the vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to distances of approximately 110 m (360 ft). See Adaptive Cruise Control on page 9-39.

{ Warning

FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. FCA does not warn of pedestrians, animals, signs, guardrails, bridges, construction barrels, or other objects. Be ready to take action and apply the brakes. For more information, see Defensive Driving on page 9-3.

FCA can be disabled through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization on page 5-45. Detecting the Vehicle Ahead

FCA warnings will not occur unless the FCA system detects a vehicle ahead. The vehicle-ahead indicator will display green when a vehicle is detected in front. Vehicles may not be detected on curves, highway exit ramps, or hills; or due to poor visibility. FCA will not detect another vehicle ahead until it is completely in the driving lane.

Collision Alert

When your vehicle approaches another vehicle too rapidly, the red collision alert symbol on the HUD, will flash on the windshield. Either eight beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times.

Tailgating Alert

The vehicle-ahead indicator will display amber when you are following a vehicle ahead much too closely.

Selecting the Alert Timing The Collision Alert control is on the steering wheel. Press [ to set the alert timing. The first button press shows the current setting on the DIC. Additional button presses will change this setting. The chosen setting will remain until it is changed and will affect the timing of both the Collision Alert and the Tailgating Alert features. The timing of both alerts will vary based on vehicle speed. The faster the vehicle speed, the farther away the alert will occur. Consider traffic and weather conditions when selecting the alert timing. The range of selectable alert timing may not be appropriate for all drivers and driving conditions. Changing the FCA timing setting automatically changes the following gap setting (Far, Medium, or Near) for the Adaptive Cruise Control (ACC) feature.

Following Distance Indication The following distance to a moving vehicle you are following is indicated in following time in seconds on the Driver Information Center (DIC). See Driver Information Center (DIC) on page 5-28. The minimum following time is 0.5 seconds away. If there is no vehicle detected ahead, or the vehicle ahead is out of sensor range, dashes will be displayed. Unnecessary Alerts FCA may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service. Cleaning the System If the FCA system does not seem to operate properly, cleaning the outside of the windshield in front of the camera sensor and the front of the vehicle may correct the issue.

Active Emergency Braking System If the vehicle has Adaptive Cruise Control (ACC) it also has the Active Emergency Braking System, which includes Intelligent Brake Assist (IBA) and the Automatic Collision Preparation (ACP) System. These systems can provide a boost to braking or automatically brake the vehicle to help avoid or lessen the severity of crashes when driving in a forward gear. Intelligent Brake Assist (IBA) IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead. Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released.

Warning (Continued)

Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes.

Brake Preparation When quickly approaching a vehicle ahead, Brake Preparation reduces brake response time by having the brake system prepared for driver braking to occur more rapidly.

Automatic Braking If ACP detects it is about to crash with the vehicle you are following that is moving or has come to a stop, and the brakes have not been applied, it may automatically brake hard. This can help to reduce crash damage and it may even help to avoid some very low speed crashes.

Automatic Braking may slow the vehicle to a complete stop to try to avoid a potential crash. The vehicle will only hold at a stop briefly. A firm press of the accelerator pedal will also release Automatic Braking.

{ Warning Automatic Braking may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. To override Automatic Braking, firmly press the accelerator pedal, if it is safe to do so.

Automatic Braking can be disabled or reduced through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization on page 5-45.

{ Warning

Using the Automatic Collision Preparation System while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system off when towing a trailer.

Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with vehicles in the side blind zone (or spot) areas. When the vehicle is moving forward, the left or right side mirror display will light up if a vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the display will flash as an extra warning not to change lanes. Since this system is part of

Lane Change Alert If equipped, the Lane Change Alert (LCA) system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on.

{ Warning

LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when
