2016 Buick Lacrosse Owners Manual

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 0 340. 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 0 192. 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.

Driving and Operating

197

{ Warning

ACC has limited braking ability and may not have time to slow the vehicle down enough to avoid a collision with another vehicle you are following. This can occur when vehicles suddenly slow or stop ahead, or enter your lane. Also see “Alerting the Driver” in this section. Complete attention is always required while driving and you should be ready to take action and apply the brakes. See Defensive Driving 0 165.

{ Warning

ACC will not detect or brake for children, pedestrians, animals, or other objects. Do not use ACC when:

. On winding and hilly roads

or when the sensors are blocked by snow, ice, or dirt. (Continued)

fog, rain, or snow conditions. ACC performance is limited under these conditions.

. On slippery roads where

fast changes in tire traction can cause excessive wheel slip.

* (Cancel) : Press to disengage ACC without erasing the selected set speed. 3 (Follow Distance Gap) : Press to select a following gap time (or distance) setting for ACC of Far, Medium, or Near.

Setting Adaptive Cruise Control If the cruise button is on when not in use, it could get pressed and go into cruise when not desired. Keep the cruise control button off when cruise is not being used. Select the set speed desired for cruise. This is the vehicle speed when no vehicle is detected in its path. ACC will not set at a speed less than 25 km/h (16 mph), although it can be resumed when driving at lower speeds. To set ACC:

1. Press ].

2. Get up to the desired speed. 3. Press and release the SET–

control on the steering wheel.

] (On/Off) : Press to turn the system on or off. The indicator turns white on the instrument cluster when ACC is turned on. RES+ (Resume/Accelerate) : Press the control up briefly to make the vehicle resume to a previously set speed, or hold upwards to accelerate. If cruise control is already active, use to increase vehicle speed. SET– (Set/Coast) : Press the control down briefly to set the speed and activate cruise control. If cruise control is already active, use to decrease vehicle speed.

4. Remove foot from the

accelerator.

After ACC is set, it may immediately apply the brakes if a vehicle ahead is detected closer than the selected following gap.

The ACC indicator displays on the instrument cluster and Head-Up Display (HUD). When ACC is active, the indicator will be lit green. Be mindful of speed limits, surrounding traffic speeds, and weather conditions when selecting the set speed.

Resuming a Set Speed If the ACC is set at a desired speed and then the brakes are applied, ACC is disengaged without erasing the set speed from memory.

To begin using ACC again, press RES+ up briefly on the steering wheel. The vehicle returns to the previously set speed.

Increasing Speed While ACC is at a Set Speed If ACC is already activated, do one of the following: . Use the accelerator to get to the higher speed. Press SET– down. Release the control and the accelerator pedal. The vehicle will now cruise at the higher speed. When the accelerator pedal is pressed, ACC will not brake because it is overridden. A warning message will appear on the Driver Information Center (DIC) and Head-Up Display (HUD). See Cruise Control Messages 0 131.

. Press and hold RES+ up until the desired set speed appears on the display, then release it.

. To increase vehicle speed in

small increments, briefly press RES+. For each press, the

. To decrease the vehicle speed in smaller increments, press SET− down briefly. For each press, the vehicle speed decreases to the next 5 km/h (1 mph) mark on the speedometer.

The speedometer reading can be displayed in either English or metric units. See Instrument Cluster 0 106. 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 range of selectable gaps may not be appropriate for all drivers and driving conditions. Changing the gap setting automatically changes the alert timing sensitivity (Far, Medium, or Near) for the Forward Collision Alert (FCA) feature. See Forward Collision Alert (FCA) System 0 208.

Alerting the Driver

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 Alert Seat will pulse five times. See “Collision/Detection Systems” under Vehicle Personalization 0 139. See Defensive Driving 0 165.

Approaching and Following a Vehicle

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.

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

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

Warning (Continued)

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 could cause a crash. Use caution when using ACC. Your complete attention is always required while driving and you should be ready to take action and apply the brakes.

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.

Driving and Operating

201

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 0 139. 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 0 190. 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 0 130. { 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.

{ Warning

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 0 130. ACC will resume operation when the accelerator pedal is not being pressed. { Warning

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.

{ Warning

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.

Driving and Operating

203

Other Vehicle Lane Changes

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.

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

Under many conditions, these systems will not:

. Detect children,

pedestrians, bicyclists, or animals.

. Detect vehicles or objects outside the area monitored by the system.

. Work at all driving speeds. . Warn you or provide you

with enough time to avoid a crash.

. Work under poor visibility or

bad weather conditions.

. Work if the detection sensor is not cleaned or is covered by ice, snow, mud, or dirt.

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.

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 0 139. 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 0 139.

Assistance Systems for Parking or Backing If equipped, the Rear Vision Camera (RVC), Rear Parking Assist (RPA), and Rear Cross Traffic Alert (RCTA) may help the driver park or avoid objects. Always check around the vehicle when parking or backing.

Rear Vision Camera (RVC) 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

{ 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.

{ Warning

The camera(s) do not display children, pedestrians, bicyclists, crossing traffic, animals, or any other object outside of the cameras’ field of view, below the bumper, or under the vehicle. Shown distances may be different from actual distances. Do not drive or park the vehicle using only these camera(s). Always check behind and around the vehicle before driving. Failure to use proper care may result in injury, death, or vehicle damage.

Parking Assist 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. These detection distances may be shorter during warmer or humid weather. Blocked sensors will not

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. 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 0 197.

{ Warning

FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, (Continued)

Warning (Continued)

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 0 165.

FCA can be disabled through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization 0 139. Detecting the Vehicle Ahead

FCA warnings will not occur unless the FCA system detects a vehicle ahead. When a vehicle is detected, the vehicle ahead indicator will display green. Vehicles may not be detected on curves, highway exit ramps, or hills, due to poor visibility; or if a vehicle ahead is partially blocked by pedestrians or other objects. FCA will not detect another vehicle ahead until it is completely in the driving lane.

{ 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.

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. When this Collision Alert occurs, the brake system may prepare for driver braking to occur more rapidly which can cause a brief, mild deceleration. Continue to apply the brake pedal as needed. Cruise control may be disengaged when the Collision Alert occurs.

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) 0 123. 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.

Driving and Operating

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.

Front Automatic Braking (FAB) System If the vehicle has Adaptive Cruise Control (ACC), it also has FAB, which includes Intelligent Brake Assist (IBA). When the system detects a vehicle ahead in your path that is traveling in the same direction that you may be about to crash into, it can provide a boost to braking or automatically brake the vehicle. This can help avoid or lessen the severity of crashes when driving in a forward gear. Depending on the situation, the vehicle may automatically brake moderately or hard. This front automatic braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See Forward Collision Alert (FCA) System 0 208.

The system works when driving in a forward gear between 10 km/h (6 mph) and 180 km/h (112 mph) for moving vehicles, or between 10 km/h (6 mph) and 55 km/h (34 mph) for stationary vehicles. It can detect vehicles up to approximately 60 m (197 ft).

{ Warning

FAB is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on FAB to brake the vehicle. FAB will not brake outside of its operating speed range and only responds to detected vehicles. FAB may not:

. Detect a vehicle ahead on

winding or hilly roads.

. Detect all vehicles,

especially vehicles with a trailer, tractors, muddy vehicles, etc.

(Continued)

Warning (Continued)

. Detect a vehicle when

weather limits visibility, such as in fog, rain, or snow.

. Detect a vehicle ahead if it

is partially blocked by pedestrians or other objects.

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.

FAB 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 FAB.

{ Warning

FAB 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 FAB, firmly press the accelerator pedal, if it is safe to do so.

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

IBA may increase vehicle braking in situations when it may not be necessary. You could block the flow of traffic. If this occurs, take your foot off the brake pedal and then apply the brakes as needed.

FAB and IBA can be disabled through vehicle personalization. See the “Auto Collision Preparation” information in “Collision/Detection Systems” under Vehicle Personalization 0 139.

{ Warning

Using FAB or IBA while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system to 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 moving vehicles in the side blind zone (or spot) areas. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving 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 the Lane Change Alert system, read the entire Lane Change Alert section before using this feature.

Lane Change Alert (LCA) If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with moving 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 changing lanes may result in injury, death, or vehicle damage. Before making a lane change, always check mirrors, glance over your shoulder, and use the turn signals.

1. SBZA Detection Zone 2. LCA Detection Zone

LCA Detection Zones The LCA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5 m (11 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2 m (6 ft) off the ground. The Side Blind Zone Alert (SBZA) warning area starts at approximately the middle of the vehicle and goes back 5 m (16 ft). Drivers are also warned of vehicles rapidly approaching from up to 70 m (230 ft) behind the vehicle. How the System Works The LCA symbol lights up in the side mirrors when the system detects a moving vehicle in the next lane over that is in the side blind zone or rapidly approaching that zone from behind. A lit LCA symbol indicates it may be unsafe to change lanes. Before making a lane change, check the LCA display, check mirrors, glance over your shoulder, and use the turn signals.

Left Side Mirror

Display

When the vehicle is started, both outside mirror LCA displays will briefly come on to indicate the system is operating. When the vehicle is in a forward gear, the left or right side mirror display will light up if a moving vehicle is detected in the next lane over in that blind zone or rapidly approaching that zone. If the turn signal is activated in the same direction as a detected vehicle, this display will flash as an extra warning not to change lanes. LCA can be disabled through vehicle personalization using the Side Blind Zone Alert option. See “Collision/Detection Systems” under Vehicle Personalization 0 139. If LCA is disabled by the driver, the LCA mirror displays will not light up.

When the System Does Not Seem to Work Properly The LCA system requires some driving for the system to calibrate to maximum performance. This calibration may occur more quickly if the vehicle is driving on a straight highway road with traffic and roadside objects (e.g., guardrails, barriers). LCA displays may not come on when passing a vehicle quickly, for a stopped vehicle, or when towing a trailer. The LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. LCA may alert to objects attached to the vehicle, such as a trailer, bicycle, or object extending out to either side of the vehicle. Attached objects may also interfere with the detection of vehicles. This is normal system operation; the vehicle does not need service. LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when

driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service. LCA may not operate when the LCA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the Vehicle" under Exterior Care 0 305. If the DIC still displays the system unavailable message after cleaning both sides of the vehicle toward the rear corners of the vehicle, see your dealer. If the LCA displays do not light up when vehicles are in the side blind zone or rapidly approaching this zone and the system is clean, the system may need service. Take the vehicle to your dealer.

When LCA is disabled for any reason other than the driver turning it off, the Side Blind Zone Alert On option will not be available on the personalization menu. Radio Frequency Information See Radio Frequency Statement 0 340.

Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. It may provide an alert if the vehicle is crossing a lane without using a turn signal in that direction. LDW uses a camera sensor to detect the lane markings at speeds of 56 km/h (35 mph) or greater.

Driving and Operating

{ Warning

The LDW system does not steer the vehicle. The LDW system may not:

. Provide enough time to

avoid a crash.

. Detect lane markings under

poor weather or visibility conditions. This can occur if the windshield or headlamps are blocked by dirt, snow, or ice; if they are not in proper condition; or if the sun shines directly into the camera.

. Detect road edges. . Detect lanes on winding or

hilly roads.

If LDW only detects lane markings on one side of the road, it will only warn you when departing the lane on the side where it has detected a lane marking. Always keep your attention on the road and

(Continued)

Warning (Continued)

maintain proper vehicle position within the lane, or vehicle damage, injury, or death could occur. Always keep the windshield, headlamps, and camera sensors clean and in good repair. Do not use LDW in bad weather conditions.

How the System Works The LDW camera sensor is on the windshield ahead of the rearview mirror. To turn LDW on and off, press @ on the center stack. The control indicator will light when LDW is on.

When LDW is on, @ is green if LDW is available to warn of a lane departure. If the vehicle crosses a detected lane marking without using the turn signal in that direction, @ changes to amber and flashes. Additionally, there will be three beeps, or the driver seat will pulse three times on the right or left, depending on the lane departure direction. When the System Does Not Seem to Work Properly The system may not detect lanes as well when there are: . Close vehicles ahead. . Sudden lighting changes, such

as when driving through tunnels.

. Banked roads. If the LDW system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help. LDW alerts may occur due to tar marks, shadows, cracks in the road, temporary or construction lane markings, or other road

imperfections. This is normal system operation; the vehicle does not need service. Turn LDW off if these conditions continue.

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. When driving in the U.S. and Canada, to help keep the engine clean and maintain optimum vehicle performance, we recommend using TOP TIER Detergent Gasolines. See www.toptiergas.com for a list of TOP TIER Detergent Gasolines.

If the vehicle has a yellow fuel cap, E85 or FlexFuel can be used in the vehicle. See E85 or FlexFuel 0 217.

Driving and Operating

215

Use regular unleaded gasoline meeting ASTM specification D4814
with a posted octane rating of 87 or higher. Do not use gasoline with an octane rating below 87, as it may cause engine damage and will lower fuel economy.

Use of Seasonal Fuels Use summer and winter fuels in the appropriate season. The fuels industry automatically modifies the fuel for the appropriate season. If fuel is left in the vehicle tank for long periods of time, driving or starting could be affected. Drive the vehicle until the fuel is at one-half tank or less, then refuel with the current seasonal fuel.

Prohibited Fuels Gasolines containing oxygenates such as ethers and ethanol, as well as reformulated gasolines, are available in some cities. If these gasolines comply with the previously described specification, then they are acceptable to use. However, E85 (85% ethanol) and

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

216

Driving and Operating

other fuels containing more than 15% ethanol must be used only in FlexFuel vehicles.

Caution

Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also damage plastic and rubber parts. That damage would not be covered under the vehicle warranty.

Some gasolines, mainly high octane racing gasolines, can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). Do not use gasolines and/or fuel additives with MMT as they can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp may turn on. If this occurs, see your dealer for service.

California Fuel Requirements If the vehicle is certified to meet California Emissions Standards, it is designed to operate on fuels that meet California specifications. See the underhood emission control label. If this fuel is not available in states adopting California Emissions Standards, the vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance might be affected. The malfunction indicator lamp could turn on and the vehicle may not pass a smog-check test. See Malfunction Indicator Lamp (Check Engine Light) 0 114. If this occurs, return to your authorized dealer for diagnosis. If it is determined that the condition is caused by the type of fuel used, repairs may not be covered by the vehicle warranty.

Fuels in Foreign Countries If planning to drive in countries outside the U.S. or Canada, the proper fuel might be hard to find. Check regional auto club or fuel retail brand websites for availability in the country where driving. Never use leaded gasoline, fuel containing methanol, manganese, or any other fuel not recommended. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.

Fuel Additives To keep fuel systems clean, TOP TIER Detergent Gasoline is recommended. See Fuel 0 215. If TOP TIER Detergent Gasoline is not available, one bottle of Fuel System Treatment PLUS added to the fuel tank at every engine oil change can help. Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer.

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

Do not use additives with E85 or FlexFuel.

E85 or FlexFuel Vehicles with a yellow fuel cap can use either unleaded gasoline or fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Fuel 0 215. The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources. To help locate fuel stations that carry E85 or FlexFuel, the U.S. Department of Energy has an alternative fuel website. See www.afdc.energy.gov/afdc/locator/ stations. E85 or FlexFuel should meet ASTM Specification D 5798 or CAN/ CGSB–3.512 in Canada. Do not use the fuel if the ethanol content is greater than 85%. Fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on.

Driving and Operating

217

The starting characteristics of E85
or FlexFuel make it unsuitable for use when temperatures fall below −18 °C (0 °F). Use gasoline or add gasoline to the E85 or FlexFuel. Because E85 or FlexFuel has less energy per liter (gallon) than gasoline, the vehicle will need to be refilled more often. See Filling the Tank 0 217.

Caution

Some additives are not compatible with E85 or FlexFuel and can harm the vehicle's fuel system. Do not add anything to E85 or FlexFuel. Damage caused by additives would not be covered by the vehicle warranty.

Caution

Do not use fuel containing methanol. It can corrode metal parts in the fuel system and also

. Do not use a cell phone

while refueling.

. Do not reenter the vehicle

while pumping fuel.

. Keep children away from

the fuel pump and never let children pump fuel.

. Fuel can spray out if the fuel

cap is opened too quickly. This spray can happen if the tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop then unscrew the cap all the way.

{ Warning

Overfilling the fuel tank by more than three clicks of a standard fill nozzle may cause:

. Vehicle performance issues, including engine stalling and damage to the fuel system.

. Fuel spills. . Potential fuel fires.

Do not top off or overfill the tank and wait a few seconds before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care 0 305.

{ Warning

If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.

The fuel cap is behind a hinged fuel door on the passenger side of the vehicle. To open the fuel door, push and release the rearward center edge of the door. If equipped, the fuel door is locked when the vehicle doors are locked. Press K on the RKE transmitter to unlock. Turn the fuel cap counterclockwise to remove. While refueling, hang the fuel cap from the hook on the fuel door. Reinstall the cap by turning it clockwise until it clicks.

Trailer Towing

General Towing Information Only use towing equipment that has been designed for the vehicle. Contact your dealer or trailering dealer for assistance with preparing the vehicle for towing a trailer. Read the entire section before towing a trailer. For towing a disabled vehicle, see Towing the Vehicle 0 302. For towing the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing 0 302.

Driving Characteristics and Towing Tips

Driving with a Trailer When towing a trailer: . Become familiar with the state

and local laws that apply to trailer towing.

. Do not tow a trailer during the first 800 km (500 mi) to prevent damage to the engine, axle, or other parts.

. Then during the first 800 km

(500 mi) of trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle.

. Vehicles can tow in D (Drive).

Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/ or hilly conditions.

. Do not use Adaptive Cruise

Control when towing.

. The Automatic Collision

Preparation System should be set to Off when towing. See Front Automatic Braking (FAB) System 0 210.

. Turn off Park Assist when

towing.

{ Warning

When towing a trailer, exhaust gases may collect at the rear of the vehicle and enter if the liftgate, trunk/hatch, or rear-most window is open. When towing a trailer:

. Do not drive with the liftgate, trunk/hatch, or rear-most window open. . Fully open the air outlets on

or under the instrument panel.

. Also adjust the climate

control system to a setting that brings in only outside air. See “Climate Control Systems” in the Index. For more information about Carbon Monoxide, see Engine Exhaust 0 185.

Towing a trailer requires a certain amount of experience. The combination you are driving is longer and not as responsive as the

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

vehicle itself. Get acquainted with the handling and braking of the rig before setting out for the open road. Before starting, check all trailer hitch parts and attachments, safety chains, electrical connectors, lamps, tires, and mirrors. If the trailer has electric brakes, start the combination moving and then apply the trailer brake controller by hand to be sure the brakes work. During the trip, check occasionally to be sure that the load is secure and the lamps and any trailer brakes still work. Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving the vehicle without a trailer. This can help to avoid heavy braking and sudden turns. Passing More passing distance is needed when towing a trailer. The combination will not accelerate as quickly and is longer so it is

necessary to go much farther beyond the passed vehicle before returning to the lane. Backing Up Hold the bottom of the steering wheel with one hand. To move the trailer to the left, move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you. Making Turns

Caution

Making very sharp turns while trailering could cause the trailer to come in contact with the vehicle. The vehicle could be damaged. Avoid making very sharp turns while trailering.

When turning with a trailer, make wider turns than normal. Do this so the trailer will not strike soft shoulders, curbs, road signs, trees,

Driving and Operating

221

or other objects. Avoid jerky or sudden maneuvers. Signal well in advance. If the trailer turn signal bulbs burn out, the arrows on the instrument cluster will still flash for turns. It is important to check occasionally to be sure the trailer bulbs are still working. Driving on Grades Reduce speed and shift to a lower gear before starting down a long or steep downgrade. If the transmission is not shifted down, the brakes might get hot and no longer work well. Vehicles can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If the engine is turned off immediately after towing at high altitude on steep uphill grades, the

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

222

Driving and Operating

vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked, preferably on level ground, with the automatic transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating 0 245. Parking on Hills

{ Warning

Parking the vehicle on a hill with the trailer attached can be dangerous. If something goes wrong, the rig could start to move. People can be injured, and both the vehicle and the trailer can be damaged. When possible, always park the rig on a flat surface.

If parking the rig on a hill: 1. Press the brake pedal, but do not shift into P (Park) yet. Turn the wheels into the curb if facing downhill or into traffic if facing uphill.

2. Have someone place chocks

under the trailer wheels.

3. When the wheel chocks are in

place, release the regular brakes until the chocks absorb the load.

4. Reapply the brake pedal. Then

apply the parking brake and shift into P (Park).

5. Release the brake pedal. Leaving After Parking on a Hill 1. Apply and hold the brake

pedal.

2. Start the engine. 3. Shift into a gear. 4. Release the parking brake. 5. Let up on the brake pedal. 6. Drive slowly until the trailer is

clear of the chocks.

7. Stop and have someone pick

up and store the chocks.

Maintenance when Trailer Towing The vehicle needs service more often when pulling a trailer. See Maintenance Schedule 0 315. Things that are especially important in trailer operation are automatic transmission fluid, engine oil, axle lubricant, belts, cooling system, and brake system. It is a good idea to inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight.

Trailer Towing (Except eAssist) Before pulling a trailer, three important considerations have to do with weight: . Weight of the trailer. . Weight of the trailer tongue. . Total weight on your vehicle's

tires.

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

Driving and Operating

223

Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 454 kg (1,000 lb). But even that can be too heavy. It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature, and how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” following. Maximum trailer weight is calculated assuming only the driver is in the tow vehicle and it has all the required trailering equipment. The weight of additional optional equipment, passengers, and cargo in the tow vehicle must be subtracted from the maximum trailer weight.

Ask your dealer for trailering information or advice, or write us at our Customer Assistance Offices. See Customer Assistance Offices 0 332. Weight of the Trailer Tongue The tongue load (1) of any trailer is an important weight to measure because it affects the total gross weight of the vehicle. The Gross Vehicle Weight (GVW) includes the curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle. If there are a lot of options, equipment, passengers, or cargo in the vehicle, it will reduce the tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow. If towing a trailer, the tongue load must be added to the GVW because the vehicle will be carrying that weight, too. See Vehicle Load Limits 0 171.

The trailer tongue (1) should weigh 10 % of the total loaded trailer weight (2). After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, adjustments might be made by moving some items around in the trailer. Total Weight on Your Vehicle's Tires Be sure the vehicle's tires are inflated to the upper limit for cold tires. These numbers can be found on the Tire and Loading Information

Buick LaCrosse Owner Manual 9159288) - 2016 - crc - 5/5/15

(GMNA-Localizing-U.S./Canada/Mexico-

224

Driving and Operating

label. See Vehicle Load Limits 0 171. Make sure not to go over the GVW limit for the vehicle, including the weight of the trailer tongue.

Trailer Towing (eAssist) The vehicle is neither designed nor intended to tow a trailer.

Towing Equipment

Hitches Use the correct hitch equipment. See your dealer or a hitch dealer for assistance. . The rear bumper on the vehicle

is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper. . Will any holes be made in the body of the vehicle when the trailer hitch is installed? If so, seal the holes when the hitch is removed. If the holes are not sealed, dirt, water, and deadly

carbon monoxide (CO) from the exhaust can get into the vehicle. See Engine Exhaust 0 185.

Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of the trailer to help prevent the tongue from contacting the road if it becomes separated from the hitch. Leave enough slack so the rig can turn. Never allow safety chains to drag on the ground. Trailer Brakes Does the trailer have its own brakes? Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Because the vehicle has antilock brakes, do not tap into the vehicle's brake system. If this is done, both brake systems will not work well or at all.

Conversions and Add-Ons

Add-On Electrical Equipment

{ Warning

The Data Link Connector (DLC) is used for vehicle service and Emission Inspection/Maintenance testing. See Malfunction Indicator Lamp (Check Engine Light) 0 114. A device connected to the Data Link Connector (DLC)—such as an aftermarket fleet or driver-behavior tracking device— may interfere with vehicle systems. This could affect vehicle operation and cause a crash. Such devices may also access information stored in the vehicle’s systems.
