Universal Remote System Programming

If equipped, these buttons are in the overhead console. This system can replace up to three remote control transmitters used to activate devices such as garage door openers, security systems, and home automation devices. These

instructions refer to a garage door opener, but can be used for other devices. Do not use the Universal Remote system with any garage door opener that does not have the stop and reverse feature. This includes any garage door opener model manufactured before April 1, 1982. Read these instructions completely before programming the Universal Remote system. It may help to have another person assist with the programming process. Keep the original hand-held transmitter for use in other vehicles as well as for future programming. Erase the programming when vehicle ownership is terminated. See “Erasing Universal Remote System Buttons” later in this section. To program a garage door opener, park outside directly in line with and facing the garage door opener receiver. Clear all people and objects near the garage door.

Make sure the hand-held transmitter has a new battery for quick and accurate transmission of the radio-frequency signal. Programming the Universal Remote System For questions or help programming the Universal Remote system, call 1-800-355-3515 or see www.homelink.com. Programming involves time-sensitive actions, and may time out causing the procedure to be repeated. To program up to three devices: 1. Hold the end of the hand-held transmitter about 3 to 8 cm (1
to 3 in) away from the Universal Remote system buttons with the indicator light in view. The hand-held transmitter was supplied by the manufacturer of the garage door opener receiver.

2. At the same time, press and

hold both the hand-held transmitter button and one of the three Universal Remote

system buttons to be used to operate the garage door. Do not release either button until the indicator light changes from a slow to a rapid flash. Then release both buttons. Some garage door openers may require substitution of Step 2 with the procedure under “Radio Signals for Canada and Some Gate Operators” later in this section.

3. Press and hold the newly

programmed Universal Remote system button for five seconds while watching the indicator light and garage door activation.

If the indicator light stays on continuously or the garage door moves when the button is pressed, then programming is complete. There is no need to complete Steps 4–6. If the indicator light does not come on or the garage door does not move, a second button press may

Instruments and Controls

be required. For a second time, press and hold the newly programmed button for five seconds. If the light stays on or the garage door moves, programming is complete. If the indicator light blinks rapidly for two seconds, then changes to a solid light and the garage door does not move, continue with programming Steps 4–6.

Learn or Smart Button

4. After completing Steps 1–3,

locate the Learn or Smart button inside the garage on the garage door opener receiver.

The name and color of the button may vary by manufacturer.

5. Press and release the Learn or

6.

Smart button. Step 6 must be completed within 30 seconds of pressing this button. Inside the vehicle, press and hold the newly programmed Universal Remote system button for two seconds and then release it. If the garage door does not move or the lamp on the garage door opener receiver does not flash, press and hold the same button a second time for two seconds, then release it. Again, if the door does not move or the garage door lamp does not flash, press and hold the same button a third time for two seconds, then release it.

The Universal Remote system should now activate the garage door. Repeat the process for programming the two remaining buttons.

Radio Signals for Canada and Some Gate Operators For questions or programming help call 1-800-355-3515 or see www.homelink.com. Canadian radio-frequency laws and some U.S. gate operators require transmitter signals to time out or quit after several seconds of transmission. This may not be long enough for the Universal Remote system to pick up the signal during programming. If the programming did not work, replace Step 2 under “Programming the Universal Remote System” with the following: Press and hold the Universal Remote system button while pressing and releasing the hand-held transmitter button every two seconds until the signal has been successfully accepted by the Universal Remote system. The Universal Remote system indicator light will flash slowly at first and then rapidly. Proceed with Step 3 under “Programming the Universal Remote System” to complete.

exterior lamps and dome lamps remain on after the door is closed for a set amount of time, then automatically turn off. For vehicles with Keyless Access, the exterior lamps automatically turn on when a door is opened after the ignition is changed to the OFF position. The dome lamps also come on after the ignition is changed to the OFF position. See Ignition Positions (Keyless Access) 0 174 or Ignition Positions (Key Access) 0 176. The exterior lamps turn off immediately by turning the exterior lamps control off. This feature can be changed. See Vehicle Personalization 0 139.

Battery Load Management The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery.

When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gauge or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed. The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all of the power needed for very high electrical loads. A high electrical load occurs when several of the following are on, such as: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.

EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power whenever needed. It can temporarily reduce the power demands of some accessories. Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a DIC message might be displayed and it is recommended that the driver reduce the electrical loads as much as possible. See Battery Voltage and Charging Messages 0 130.

Battery Power Protection The battery saver feature is designed to protect the vehicle's battery. If the exterior lamps or any interior light is left on and the ignition is turned off, the battery rundown

Climate Control Influence on eAssist Operation and Fuel Economy (If Equipped) The climate control system depends on other vehicle systems for heat and power input. Certain climate control settings can lead to higher fuel usage and/or fewer auto stops. The following are climate control settings that use more fuel: . Comfort air conditioning mode. . The defrost mode. . Extreme temperature settings, such as 15 °C (60 °F) or 32 °C (90 °F).

. High fan speed settings.

To help reduce fuel usage: . Use the full automatic control as

described under “Automatic Operation” following.

. Select a temperature setting that

is higher in hot weather and lower in cold weather.

. Turn off the air conditioning

when it is not needed.

. Only use defrost to clear the

windows.

Automatic Operation The system automatically controls the fan speed, air delivery, air conditioning, and recirculation in order to heat or cool the vehicle to the desired temperature. When the AUTO indicator light is on, the system is in full automatic operation. If the air delivery mode, fan speed, recirculation, or air conditioning setting is adjusted, the AUTO indicator turns off and the selected settings will appear on the display.

To place the system in automatic mode: 1. Press AUTO. 2. Set the temperature. Allow the system time to stabilize. Adjust the temperature as needed for best comfort.

To improve fuel efficiency and to cool the vehicle faster, recirculation may be automatically selected in warm weather. The recirculation light will not come on. Press @ to select recirculation; press it again to select outside air. Q / R (Driver and Passenger Temperature Controls) : The temperature can be adjusted separately for the driver and the passenger. Press to increase or decrease the temperature. SYNC (Synchronized Temperature) : Press to link all climate zone settings to the driver settings. The SYNC indicator light will turn on. When the passenger settings are adjusted, the SYNC indicator light is off.

Manual Operation O (Power) : Press to turn the fan off or on. Q 9 / 9R (Fan Control) : Press to increase or decrease the fan speed. The fan speed setting appears on the main display. Pressing either button cancels automatic fan control and the fan is controlled manually. Press AUTO to return to automatic operation. Air Delivery Mode Controls : Press X, Y, or [ to change the direction of the airflow. The current mode appears in the display screen. Pressing either button cancels automatic air delivery control and the direction of the airflow is controlled manually. Press AUTO to return to automatic operation. To change the current mode, select one of the following: X (Defog) : Clears the windows of fog or moisture. Air is directed to the windshield and floor outlets. Y (Vent) : Air is directed to the instrument panel outlets.

[ (Floor) : Air is directed to the floor outlets. 0 MAX (Defrost) : Clears the windshield of fog or frost more quickly. Air is directed to the windshield. For best results, clear all snow and ice from the windshield before defrosting. For eAssist vehicles that have the auto defog feature, auto stops can occur in defrost mode. In this mode, the auto stops are shorter and less frequent than other air delivery modes to prevent window fogging. A/C (Comfort Air Conditioning) : Press to turn the air conditioning system on or off. If the climate control system is turned off or the outside temperature falls below freezing, the air conditioner will not run. Pressing this button cancels automatic air conditioning and turns off the air conditioner. Press AUTO to return to automatic operation and the air conditioner runs automatically as needed. When the

indicator light is on, the air conditioner runs automatically to cool the air inside the vehicle or to dry the air needed to defog the windshield faster. For eAssist vehicles, an auto stop may occur if the climate control system determines the a/c compressor can be shut off and still maintain comfort levels with minimal windshield fogging. Eco A/C (For eAssist Vehicles) : Press to cycle between the off, eco and comfort air conditioning modes. The indicator will be lit green in eco, amber in comfort, and turns off when there is no A/C function. If the fan is turned off, the A/C will not run. The eco A/C setting balances fuel economy and air conditioning comfort. In warm weather conditions, auto stops may occur more frequently and the vehicle interior may be warmer as compared to the comfort air conditioning. This setting allows higher humidity inside the vehicle and window fogging before the engine restarts.

Pressing the 0 button during an auto stop may restart the engine to prevent window fogging. To reach comfort levels quickly during an auto stop, the engine will restart if the air conditioner is off and AUTO or A/C is selected. If temperature controls are adjusted cooler by more than 1 °C (1 °F) during an auto stop, the engine will restart to ensure that comfort is reached. @ (Recirculation) : Press to turn on recirculation. An indicator light comes on. Air is recirculated to quickly cool the air inside the vehicle or prevent odors from entering. Press again to change to outside air and the indicator light turns off. Press AUTO to return to automatic operation and recirculation runs automatically as needed. The indicator light is off. The Air Quality Sensor may operate the recirculation mode automatically. See “Climate and Air Quality” under Vehicle Personalization 0 139.

Auto Defog : The climate control system may have a sensor to automatically detect high humidity inside the vehicle. When high humidity is detected, the climate control system may adjust to outside air supply and turn on the air conditioner. The fan speed may slightly increase to help prevent fogging. If the climate control system does not detect possible window fogging, it returns to normal operation. For eAssist vehicles, there may be shorter and less frequent auto stops when auto defog is in use. To turn Auto Defog off or on, see “Climate and Air Quality” under Vehicle Personalization 0 139. Rear Window Defogger = (Rear Window Defogger) : Press to turn the rear window defogger on or off. An indicator light on the button comes on to show that the rear window defogger is on. The defogger can be turned off by turning the ignition to ACC/ ACCESSORY or LOCK/OFF.

The rear window defogger can be set to automatic operation. See “Climate and Air Quality” under Vehicle Personalization 0 139. When auto rear defog is selected, the rear window defogger turns on automatically when the interior temperature is cold and the outside temperature is about 4 °C (40 °F) and below. The auto rear defogger turns off automatically after about 10 minutes, or after five minutes if the outside temperature is not as cold. For eAssist vehicles, auto rear defog will only run during a remote start and the feature is not available in the vehicle personalization menu. If the vehicle is equipped with heated outside rearview mirrors, they turn on when the rear window defogger button is on and help to clear fog or frost from the surface of the mirror. See Heated Mirrors 0 43.

Air Vents Use the louvers on the air vents to change the direction of the airflow. To open the vent, move the thumbwheel to t. To close the vent, move the thumbwheel to l. For vehicles with eAssist, there is a battery cooling air vent on the shelf behind the rear passenger seats below the rear window. Keep this air inlet clear from items that may block airflow. Proper airflow is required to keep the eAssist battery and control system cool.

Operation Tips . Keep all outlets open whenever

possible for best system performance.

. Keep the path under all seats

clear of objects to help circulate the air inside the vehicle more effectively.

. Use of non-GM approved hood deflectors can adversely affect the performance of the system.

Driving Information

Distracted Driving Distraction comes in many forms and can take your focus from the task of driving. Exercise good judgment and do not let other activities divert your attention away from the road. Many local governments have enacted laws regarding driver distraction. Become familiar with the local laws in your area. To avoid distracted driving, always keep your eyes on the road, hands on the wheel, and mind on the drive. . Do not use a phone in

demanding driving situations. Use a hands-free method to place or receive necessary phone calls.

. Watch the road. Do not read,

take notes, or look up information on phones or other electronic devices.

. Designate a front seat

passenger to handle potential distractions.

. Become familiar with vehicle

features before driving, such as programming favorite radio stations and adjusting climate control and seat settings. Program all trip information into any navigation device prior to driving.

. Wait until the vehicle is parked

to retrieve items that have fallen to the floor.

. Stop or park the vehicle to tend

to children.

. Keep pets in an appropriate

carrier or restraint.

. Avoid stressful conversations while driving, whether with a passenger or on a cell phone.

{ Warning

Taking your eyes off the road too long or too often could cause a crash resulting in injury or death. Focus your attention on driving.

Refer to the infotainment manual for more information on using that system, including pairing and using a cell phone

Defensive Driving Defensive driving means “always expect the unexpected.” The first step in driving defensively is to wear the safety belt. See Safety Belts 0 59. . Assume that other road users

(pedestrians, bicyclists, and other drivers) are going to be careless and make mistakes. Anticipate what they might do and be ready.

. Allow enough following distance

between you and the driver in front of you.

. Focus on the task of driving.

Drunk Driving Death and injury associated with drinking and driving is a global tragedy.

{ Warning

Drinking and then driving is very dangerous. Your reflexes, perceptions, attentiveness, and judgment can be affected by even a small amount of alcohol. You can have a serious — or even fatal — collision if you drive after drinking. Do not drink and drive or ride with a driver who has been drinking. Ride home in a cab; or if you are with a group, designate a driver who will not drink.

Control of a Vehicle Braking, steering, and accelerating are important factors in helping to control a vehicle while driving.

Braking Braking action involves perception time and reaction time. Deciding to push the brake pedal is perception time. Actually doing it is reaction time.

Driving and Operating

165

Average driver reaction time is about three-quarters of a second. In that time, a vehicle moving at 100 km/h (60 mph) travels 20 m (66 ft), which could be a lot of distance in an emergency. Helpful braking tips to keep in mind include: . Keep enough distance between

you and the vehicle in front of you.

. Avoid needless heavy braking. . Keep pace with traffic. If the engine ever stops while the vehicle is being driven, brake normally but do not pump the brakes. Doing so could make the pedal harder to push down. If the engine stops, there will be some power brake assist but it will be used when the brake is applied. Once the power assist is used up, it can take longer to stop and the brake pedal will be harder to push.

166

Driving and Operating

Steering

Electric Power Steering If the vehicle has electric power steering it does not have power steering fluid. Regular maintenance is not required. If power steering assist is lost due to a system malfunction, the vehicle can be steered, but may require increased effort. See your dealer if there is a problem. If the steering wheel is turned until it reaches the end of its travel and is held against that position for an extended period of time, power steering assist may be reduced. If the steering assist is used for an extended period of time, power assist may be reduced. Normal use of the power steering assist should return when the system cools down. See specific vehicle steering messages under Vehicle Messages 0 130.

Variable Effort Steering Some vehicles have a steering system that varies the amount of effort required to steer the vehicle in relation to the speed of the vehicle. The amount of steering effort required is less at slower speeds to make the vehicle more maneuverable and easier to park. At faster speeds, the steering effort increases to provide a sport-like feel to the steering. This provides maximum control and stability. Hydraulic Power Steering If the vehicle has hydraulic power steering, it may require maintenance. See Power Steering Fluid (2.4L L4 Engine and 3.6L V6 Engine with FWD) 0 247
or Power Steering Fluid (3.6L V6 Engine with AWD) 0 247. If power steering assist is lost because the engine stops or there is a system malfunction, the vehicle can be steered but may require increased effort. See your dealer if there is a problem.

Caution

If the steering wheel is turned until it reaches the end of its travel, and is held in that position for more than 15 seconds, damage may occur to the power steering system and there may be loss of power steering assist.

Curve Tips . Take curves at a reasonable

speed.

. Reduce speed before entering a

curve.

. Maintain a reasonable, steady

speed through the curve.

. Wait until the vehicle is out of the curve before accelerating gently into the straightaway.

Steering in Emergencies . There are some situations when steering around a problem may be more effective than braking.

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

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

. Holding both sides of the

steering wheel allows you to turn 180 degrees without removing a hand.

. Antilock Brake System (ABS) allows steering while braking.

Off-Road Recovery

The vehicle's right wheels can drop off the edge of a road onto the shoulder while driving. Follow these tips: 1. Ease off the accelerator and then, if there is nothing in the way, steer the vehicle so that it straddles the edge of the pavement.

2. Turn the steering wheel about one-eighth of a turn, until the right front tire contacts the pavement edge.

3. Turn the steering wheel to go

straight down the roadway.

Loss of Control

Skidding There are three types of skids that correspond to the vehicle's three control systems: . Braking Skid — wheels are not

rolling.

. Steering or Cornering Skid —

too much speed or steering in a curve causes tires to slip and lose cornering force.

Driving and Operating

167

. Acceleration Skid — too much

throttle causes the driving wheels to spin.

Defensive drivers avoid most skids by taking reasonable care suited to existing conditions, and by not overdriving those conditions. But skids are always possible. If the vehicle starts to slide, follow these suggestions: . Ease your foot off the

accelerator pedal and steer the way you want the vehicle to go. The vehicle may straighten out. Be ready for a second skid if it occurs.

. Slow down and adjust your driving according to weather conditions. Stopping distance can be longer and vehicle control can be affected when traction is reduced by water, snow, ice, gravel, or other material on the road. Learn to recognize warning clues — such as enough water, ice, or packed snow on the road to make a mirrored surface — and slow down when you have any doubt.

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

168

Driving and Operating

. Try to avoid sudden steering,

acceleration, or braking, including reducing vehicle speed by shifting to a lower gear. Any sudden changes could cause the tires to slide.

Remember: Antilock brakes help avoid only the braking skid.

Driving on Wet Roads Rain and wet roads can reduce vehicle traction and affect your ability to stop and accelerate. Always drive slower in these types of driving conditions and avoid driving through large puddles and deep-standing or flowing water.

{ Warning

Wet brakes can cause crashes. They might not work as well in a quick stop and could cause pulling to one side. You could lose control of the vehicle.

(Continued)

Warning (Continued)

After driving through a large puddle of water or a car/vehicle wash, lightly apply the brake pedal until the brakes work normally. Flowing or rushing water creates strong forces. Driving through flowing water could cause the vehicle to be carried away. If this happens, you and other vehicle occupants could drown. Do not ignore police warnings and be very cautious about trying to drive through flowing water.
