The solar sensor on top of the instrument panel near the windshield monitors the solar heat. The climate control system uses the sensor information to adjust the temperature, fan speed, recirculation, and air delivery mode for best comfort. If the sensor is covered, the automatic climate control system may not work properly.

Move the thumbwheels (1) left or right to open or close off the airflow. Use the slider knobs (2) on the air vents to change the direction of the airflow.

Move the thumbwheels (1) up or down to open or close off the airflow. Use the slider knobs (2) to change the direction of the airflow.

Operation Tips . Keep all outlets open whenever

possible for best system performance.

Climate Controls

. Keep the paths 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.

. Do not attach any devices to the

air vent louvers. This restricts airflow and may cause damage to the air vents.

Maintenance

Passenger Compartment Air Filter The passenger compartment air filter reduces most of the pollen and dust from the air that may enter the vehicle. The filter will need to be replaced periodically. See Maintenance Schedule on page 11-3. Using the climate control system without an air filter installed is not recommended. Water or other debris could enter the system and result in leaks or noises. Always install a new filter when removing the old filter. For more information on filter replacement, see your dealer.

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 section 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 on page 3-13. . 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.

Driving and Operating

9-3

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. 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.

Black plate (4,1)

Steering in Emergencies

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

. Holding both sides of the

steering wheel allows you to turn 180 degrees without removing a hand. The Antilock Brake System (ABS) allows steering while braking.

Off-Road Recovery

9-4

Driving and Operating

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.

Steering

Electric Power Steering 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 Service Vehicle Messages on page 5-35. See your dealer if there is a problem. 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.

Chevrolet Impala Owner Manual (GMNA-Localizing-U.S./Canada-7576026) - 2015 - CRC 1st Edition - 4/2/14

Black plate (5,1)

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.

. 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. 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.

Track Events and Competitive Driving Racing, track testing, or competitive driving may affect the vehicle warranty. See the warranty manual before using the vehicle for racing or other competitive driving.

{ Caution

{ Caution

{ Warning

If the vehicle is used for track events and competitive driving, the engine may use more oil than it would with normal use. Low oil levels can damage the engine. Check the oil level often and maintain the proper level. See Engine Oil on page 10-8.

For the 2.5L L4 Engine Only: Add and keep the oil level at 1 L (1 qt) above the high mark when driving under these conditions. For information on how to check and add oil, see Engine Oil on page 10-8
For the 3.6L Engine Only: Add and keep the oil level at 0.5 L (0.5 qt) above the high mark when driving under these conditions. For information on how to check and add oil, see Engine Oil on page 10-8.

During a first time track or racing event, high rear axle temperatures can occur. Damage could be caused to the rear axle and would not be covered by the vehicle warranty. Do not drive as long or as fast the first time the vehicle is driven on the track or raced.

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.

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. 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.

Hydroplaning Hydroplaning is dangerous. Water can build up under the vehicle's tires so they actually ride on the water. This can happen if the road is wet enough and you are going fast enough. When the vehicle is hydroplaning, it has little or no contact with the road. There is no hard and fast rule about hydroplaning. The best advice is to slow down when the road is wet. Other Rainy Weather Tips Besides slowing down, other wet weather driving tips include: . Allow extra following distance. . Pass with caution. . Keep windshield wiping

equipment in good shape.

. Keep the windshield washer fluid

reservoir filled.

. Have good tires with proper

tread depth. See Tires on page 10-38.

Turn off cruise control.

Hill and Mountain Roads Driving on steep hills or through mountains is different than driving on flat or rolling terrain. Tips for driving in these conditions include: . Keep the vehicle serviced and in

good shape.

. Check all fluid levels and brakes,

tires, cooling system, and transmission.

. Shift to a lower gear when going

down steep or long hills.

{ Warning

Using the brakes to slow the vehicle on a long downhill slope can cause brake overheating, can reduce brake performance, and could result in a loss of braking. Shift the transmission to a lower gear to let the engine assist the brakes on a steep downhill slope.

Driving and Operating

9-7

{ Warning

Coasting downhill in N (Neutral) or with the ignition off is dangerous. This can cause overheating of the brakes and loss of steering. Always have the engine running and the vehicle in gear.

. Stay in your own lane. Do not swing wide or cut across the center of the road. Drive at speeds that let you stay in your own lane.

. Be alert on top of hills;

something could be in your lane (stalled car, accident).

. Pay attention to special road

signs (falling rocks area, winding roads, long grades, passing or no-passing zones) and take appropriate action.

Driving and Operating

Winter Driving

Driving on Snow or Ice Drive carefully when there is snow or ice between the tires and the road, creating less traction or grip. Wet ice can occur at about 0°C (32° F) when freezing rain begins to fall, resulting in even less traction. Avoid driving on wet ice or in freezing rain until roads can be treated with salt or sand. Drive with caution, whatever the condition. Accelerate gently so traction is not lost. Accelerating too quickly causes the wheels to spin and makes the surface under the tires slick, so there is even less traction. Traction Control should be turned on. See Traction Control/Electronic Stability Control on page 9-31. The Antilock Brake System (ABS) improves vehicle stability during hard stops on slippery roads, but

apply the brakes sooner than when on dry pavement. See Antilock Brake System (ABS) on page 9-28. Allow greater following distance on any slippery road and watch for slippery spots. Icy patches can occur on otherwise clear roads in shaded areas. The surface of a curve or an overpass can remain icy when the surrounding roads are clear. Avoid sudden steering maneuvers and braking while on ice. Turn off cruise control on slippery surfaces. Blizzard Conditions Being stuck in snow can be a serious situation. Stay with the vehicle unless there is help nearby. If possible, use Roadside Assistance. See Roadside Assistance Program on page 13-5. To get help and keep everyone in the vehicle safe:

Turn on the hazard warning flashers.

Tie a red cloth to an outside mirror.

{ Warning

Snow can trap engine exhaust under the vehicle. This may cause exhaust gases to get inside. Engine exhaust contains carbon monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. If the vehicle is stuck in the snow: . Clear away snow from around

the base of your vehicle, especially any that is blocking the exhaust pipe.

. Check again from time to

time to be sure snow does not collect there.

. Open a window about 5 cm

(2 in) on the side of the vehicle that is away from the wind to bring in fresh air.

Warning (Continued)

. Fully open the air outlets on

or under the instrument panel.

. Adjust the climate control

system to a setting that circulates the air inside the vehicle and set the fan speed to the highest setting. See “Climate Control Systems”.

For more information about carbon monoxide, see Engine Exhaust on page 9-24.

To save fuel, run the engine for only short periods as needed to warm the vehicle and then shut the engine off and close the window most of the way to save heat. Repeat this until help arrives but only when you feel really uncomfortable from the cold. Moving about to keep warm also helps.

Driving and Operating

9-9

If it takes some time for help to arrive, now and then when you run the engine, push the accelerator pedal slightly so the engine runs faster than the idle speed. This keeps the battery charged to restart the vehicle and to signal for help with the headlamps. Do this as little as possible to save fuel.

If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method. See Traction Control/Electronic Stability Control on page 9-31.

{ Warning

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The

(Continued)

Warning (Continued)

vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph).

Rocking the Vehicle to Get it Out Turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction system. Shift back and forth between R (Reverse) and a low forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear. Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get

Vehicle Load Limits It is very important to know how much weight the vehicle can carry. This weight is called the vehicle capacity weight and includes the weight of all occupants, cargo, and all nonfactory-installed options. Two labels on the vehicle show how much weight it may properly carry, the Tire and Loading Information label and the Certification label. { Warning

pillar (B-pillar). The Tire and Loading Information label shows the number of occupant seating positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the tire size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires on page 10-38 and Tire Pressure on page 10-45. There is also important loading information on the Certification label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. See “Certification Label” later in this section.

“Steps for Determining Correct Load Limit– 1. Locate the statement "The

combined weight of occupants and cargo should never exceed XXX kg or XXX lbs." on your vehicle’s placard.

2. Determine the combined weight of the driver and passengers that will be riding in your vehicle.

3. Subtract the combined weight of the driver and passengers from XXX kg or XXX lbs.

4. The resulting figure equals

the available amount of cargo and luggage load capacity. For example, if the "XXX" amount equals 1400 lbs. and there will be five 150 lb passengers in your vehicle, the amount of available cargo

and luggage load capacity is 650 lbs. (1400-750 (5 x 150) = 650 lbs.)

5. Determine the combined

6.

weight of luggage and cargo being loaded on the vehicle. That weight may not safely exceed the available cargo and luggage load capacity calculated in Step 4. If your vehicle will be towing a trailer, load from your trailer will be transferred to your vehicle. Consult this manual to determine how this reduces the available cargo and luggage load capacity of your vehicle.”

See Trailer Towing (Bi-Fuel) on page 9-61 or Trailer Towing (All except Bi-Fuel) on page 9-61 for important information on towing a trailer, towing safety rules, and trailering tips.

fuel, and cargo. Never exceed the GVWR for the vehicle, or the Gross Axle Weight Rating (GAWR) for either the front or rear axle. And, if there is a heavy load, it should be spread out. See “Steps for Determining Correct Load Limit” earlier in this section.

{ Warning

Do not load the vehicle any heavier than the Gross Vehicle Weight Rating (GVWR), or either the maximum front or rear Gross Axle Weight Rating (GAWR). This can cause systems to break and change the way the vehicle handles. This could cause loss of control and a crash. Overloading can also shorten the life of the vehicle.

If you put things inside the vehicle — like suitcases, tools, packages, or anything else — they will go as fast as the vehicle goes. If you have to stop or turn quickly, or if there is a crash, they will keep going.

{ Warning

Things inside the vehicle can strike and injure people in a sudden stop or turn, or in a crash.

. Put things in the cargo

area of the vehicle. In the cargo area, put them as far forward as possible. Try to spread the weight evenly.

The vehicle may have an electronic keyless ignition with pushbutton start. Pressing the button cycles it through three modes: ACC/ACCESSORY, ON/RUN/START, and Stopping the Engine/OFF. The transmitter must be in the vehicle for the system to operate. If the pushbutton start is not working, the vehicle may be near a strong radio antenna signal causing interference to the Keyless Access system. See Remote Keyless Entry (RKE) System Operation on page 2-3. To shift out of P (Park), the vehicle must be in ACC/ACCESSORY or ON/RUN and the brake pedal must be applied. Stopping the Engine/LOCK/ OFF (No Indicator Lights): When the vehicle is stopped, press the ENGINE START/STOP button once to turn the engine off.

If the vehicle is in P (Park), the ignition will turn off, and Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9-22.

Stop/Start System

{ Warning

Exiting the vehicle without first shifting into P (Park) may cause the vehicle to move. You or others may be injured. Because the vehicle has the auto engine stop/ start feature, the vehicle's engine might seem to be shut off; however, once the brake pedal is released, the engine will start up again. Shift to P (Park) and turn the ignition to LOCK/OFF, before exiting the vehicle.

If equipped with the 2.5L L4 Engine, the vehicle has a fuel saving stop/ start system to shut off the engine to help conserve fuel.

Auto Engine Stop/Start When the brakes are applied and the vehicle is at a complete stop, the engine may turn off. When stopped, the tachometer displays AUTO STOP. See Tachometer on page 5-12. When the brake pedal is released or the accelerator pedal pushed, the engine will restart. Auto stop may be deactivated if: . A minimum vehicle speed is not

reached. The engine or transmission is not at the required operating temperature. The outside temperature is not in the required operating range, typically below -10°C (14°F) or above 50°C (122°F). The shift lever is in any gear other than D (Drive).

The battery charge is low. The interior comfort level has not reached the required level for the climate control system or defog settings. Use the eco (green indicator on) air conditioning mode for better efficiency. See Dual Automatic Climate Control System on page 8-3. The auto stop time is greater than two minutes.

Engine Heater The engine coolant heater, if equipped, can help in cold weather conditions at or below −18° C (0°F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting the vehicle. An internal thermostat in the plug end of the cord will prevent engine coolant heater operation at temperatures above −18°C (0°F).

If you have to leave the vehicle with the engine running, be sure the vehicle is in P (Park) and the parking brake is firmly set before you leave it. After you have moved the shift lever into P (Park), hold the regular brake pedal down. Then, see if you can move the shift lever away from P (Park) without first pressing the button. If you can, it means that the shift lever was not fully locked in P (Park). Torque Lock Torque lock is when the weight of the vehicle puts too much force on the parking pawl in the transmission. This happens when parking on a hill and shifting the transmission into P (Park) is not done properly, then it is difficult to shift out of P (Park). To prevent torque lock, set the parking brake and then shift into P (Park). To find out how, see “Shifting Into Park” listed previously.

If torque lock does occur, your vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park). If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips on page 9-58.

Shifting out of Park This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to: . Prevent ignition key removal (if equipped) unless the shift lever is in P (Park) with the shift lever button fully released.

. Prevent movement of the shift

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

Driving and Operating

9-23

The shift lock release 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 page 10-66. To shift out of P (Park): 1. Apply the brake pedal. 2. Place the ignition in ON/RUN. 3. Press the shift lever button. 4. Move the shift lever to the

desired position.

Driving and Operating

Brakes

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 5-21.

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
