2013 Chevrolet Impala Owners Manual

Notice: Cranking the engine for long periods of time, by returning the key to the START position immediately after cranking has ended, can overheat and damage the cranking motor, and drain the battery. Wait at least 15 seconds between each try, to let the cranking motor cool down. 2.

If the engine does not start after five to 10 seconds, especially in very cold weather (below −18°C or 0°F), it could be flooded with too much gasoline. Try pushing the accelerator pedal all the way to the floor and holding it there as you hold the key in START

for up to a maximum of 15 seconds. Wait at least 15 seconds between each try, to allow the cranking motor to cool down. When the engine starts, let go of the key and accelerator. If the vehicle starts briefly but then stops again, repeat these steps. This clears the extra gasoline from the engine. Do not race the engine immediately after starting it. Operate the engine and transmission gently until the oil warms up and lubricates all moving parts.

Notice: If you add electrical parts or accessories, you could change the way the engine operates. Any resulting damage would not be covered by the vehicle warranty. See Add-On Electrical Equipment on page 9‑41.

Engine Heater The engine coolant heater can provide easier starting and better fuel economy during engine warm‐

up in cold weather conditions at or below −18°C (0°F). Vehicles with an engine coolant heater should be plugged in at least four hours before starting. To Use the Engine Heater 1. Turn off the engine. 2. Open the hood and unwrap the

electrical cord. The cord is attached to the diagonal brace on the driver side of the engine compartment.

3. Plug it into a normal, grounded

110-volt AC outlet.

{ WARNING Plugging the cord into an ungrounded outlet could cause an electrical shock. Also, the wrong kind of extension cord could overheat and cause a fire. You could be seriously injured. Plug the cord into a properly grounded (Continued)

Leaving the Vehicle With the Engine Running

{ WARNING

It can be dangerous to leave the vehicle with the engine running. It could overheat and catch fire. It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 9‑17. If you are towing a trailer, see Driving Characteristics and Towing Tips on page 9‑36.

If you have to leave the vehicle with the engine running, be sure your vehicle is in P (Park) and the parking brake is firmly set before you leave it. See Parking Brake on page 9‑24 for more information. 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 and 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” in this section. 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).

Shifting out of Park

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

unless the shift lever is in P (Park).

. Prevent movement of the shift

lever out of P (Park), unless the ignition is in ON/RUN and the regular brake pedal is applied. The shift lock is always functional except in the case of a 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 10‑61.

maintain brake application. Then move the shift lever into another gear. See Shifting out of Park on page 9‑18. R (Reverse): Use this gear to back up. Notice: Shifting to R (Reverse) while the vehicle is moving forward could damage the transmission. The repairs would not be covered by the vehicle warranty. Shift to R (Reverse) only after the vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice, or sand without damaging the transmission, see If the Vehicle Is Stuck on page 9‑8. N (Neutral): In this position, the engine does not connect with the wheels. To restart the engine when the vehicle is already moving, use N (Neutral) only. Also, use N (Neutral) when the vehicle is being towed.

WARNING (Continued)

Do not leave the vehicle when the engine is running. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 9‑17 and Driving Characteristics and Towing Tips on page 9‑36.

Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. You must fully apply the regular brake before shifting from P (Park) when the ignition key is in ON/RUN. If you cannot shift out of P (Park), ease pressure on the shift lever, then push the shift lever all the way into P (Park) as you

P (Park): This position locks the front wheels. It is the best position to use when starting the engine because the vehicle cannot move easily.

Driving and Operating

{ WARNING

Shifting into a drive gear while the engine is running at high speed is dangerous. Unless your foot is firmly on the brake pedal, the vehicle could move very rapidly. You could lose control and hit people or objects. Do not shift into a drive gear while the engine is running at high speed.

Notice: Shifting out of P (Park) or N (Neutral) with the engine running at high speed may damage the transmission. The repairs would not be covered by the vehicle warranty. Be sure the engine is not running at high speed when shifting the vehicle.

D (Drive): This position is for normal driving. It provides the best fuel economy. If you need more power for passing, and you are: . Going less than 56 km/h

(35 mph), push the accelerator pedal about halfway down.

. Going about 56 km/h (35 mph) or

more, push the accelerator all the way down.

Notice: If the vehicle seems to accelerate slowly or not shift gears when you go faster, and you continue to drive the vehicle that way, you could damage the transmission. Have the vehicle serviced right away. You can drive in L (Low) when you are driving less than 56 km/h (35 mph) and D (Drive) for higher speeds until then. Downshifting the transmission in slippery road conditions could result in skidding, see "Skidding" under Loss of Control on page 9‑4.

L (Low): This position gives you access to gear ranges. This provides more engine braking but lower fuel economy than D (Drive). You can use it on very steep hills, or in deep snow or mud. See the following text on Manual Mode.

Manual Mode

Electronic Range Select (ERS) Mode

ERS mode allows you to choose the top-gear limit of the transmission, which can help control the vehicle's

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

speed while driving downhill or towing a trailer. The vehicle has an electronic shift position indicator within the instrument cluster. When using the ERS mode a number will display next to the L, indicating the current range that has been selected. To use this feature: 1. Move the shift lever to L (Low). 2. Press the + (Plus) or − (Minus)

button located on the left side of the steering wheel, to increase or decrease the gear range available.

When you shift from D (Drive) to L (Low), the transmission will shift to a pre-determined lower gear range.

The highest gear available for this pre-determined range is displayed next to the L in the DIC. The number displayed in the DIC is the highest gear that the transmission will be allowed to operate in. All gears below that number are available. For example, when 4 (Fourth) is shown next to the L, 1 (First) through 4 (Fourth) gears are automatically shifted by the vehicle. The transmission will not shift into 5 (Fifth) until the + (Plus) button is used or you shift back into D (Drive). While in L (Low), the transmission will prevent shifting to a lower gear range if the engine speed is too high.

Brakes

Antilock Brake System (ABS) This vehicle has the Antilock Brake System (ABS), an advanced electronic braking system that helps prevent a braking skid. When the engine is started and 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 5‑18.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

Black plate (24,1)

9-24

Driving and Operating

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 that 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 the driver steer around the obstacle while braking hard. As the brakes are applied, the computer keeps receiving updates on wheel speed and controls braking pressure accordingly. Remember: ABS does not change the time needed to get a foot up to the brake pedal or always decrease stopping distance. If you get too close to the vehicle in front of you,

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

Parking Brake

The parking brake is located to the left of the brake pedal, near the driver door. To set the parking brake, hold the brake pedal down, then push down the parking brake pedal. To release the parking brake, hold the brake pedal down and push the parking brake pedal. When you lift your foot off the parking brake pedal, the pedal will follow it to the released position.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

Driving and Operating

9-25

A warning chime will sound and a brake warning light located on the instrument panel cluster will come on, if the parking brake is set, the ignition is on, and the vehicle speed is greater than 8 km/h (5 mph). Notice: Driving with the parking brake on can overheat the brake system and cause premature wear or damage to brake system parts. Make sure that the parking brake is fully released and the brake warning light is off before driving. If you are towing a trailer and parking on any hill, see Driving Characteristics and Towing Tips on page 9‑36.

Ride Control Systems

Traction Control System (TCS) The vehicle may have a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. The system operates only if it senses that one or both of the front wheels are spinning or beginning to lose traction. When this happens, the system reduces engine power and may also upshift the transmission and apply the front brakes to limit wheel spin.

The system may be heard or felt while it is working, but this is normal. If cruise control is being used when TCS begins to limit wheel spin, the cruise control will automatically disengage. Cruise control may be reengaged when road conditions allow. See Cruise Control on page 9‑28. The TCS operates in all transmission shift lever positions. But the system can upshift the transmission only as high as the shift lever position chosen, so use the lower gears only when necessary. See Automatic Transmission on page 9‑20.

This light will flash when the TCS is limiting wheel spin.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

9-26

Driving and Operating

When the system is on, this warning light comes on and stays on if there is a problem. A SERVICE TRACTION CONTROL message also appears on the DIC. When this warning light is on, the system will not limit wheel spin. Adjust your driving accordingly. See Ride Control System Messages on page 5‑30 for more information. To limit wheel spin, especially in slippery road conditions, TCS should always be left on. But the system can be turned off if needed. Turn the system off if the vehicle gets stuck in sand, mud, or snow and rocking the vehicle is required. See If the Vehicle Is Stuck on page 9‑8 for more information.

To turn the system on or off, press the ESC OFF button located on the instrument panel. When the system is turned off, the TRACTION CONTROL OFF message appears on the DIC. If the traction control system is limiting wheel spin when the button is pressed to turn the system off, the TRACTION CONTROL OFF message will appear on the DIC and the system will turn off right away. Press the ESC OFF button again to turn the system back on. The TRACTION CONTROL ON message will appear in the DIC. Adding non‐dealer accessories can affect the vehicle performance. See Accessories and Modifications on page 10‑3 for more information.

Electronic Stability Control (ESC) Your vehicle may have an Electronic Stability Control (ESC) system which combines antilock brake,

traction, and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions. When you first start your vehicle and begin to drive away, the system performs several diagnostic checks to ensure there are no problems. You may hear or feel the system working. This is normal and does not mean there is a problem with your vehicle. The system should initialize before the vehicle reaches 32 km/h (20 mph). If the system fails to turn on or activate due to a fault, the ESC/TCS light will be on solid, and the SERVICE STABILITRAK message will be displayed. If the system fails to turn on or activate due to it not initializing, the DIC will display STABILITRAK INITIALIZING. For more information, see Ride Control System Messages on page 5‑30.

conditions, you should always leave the system on. But, you can turn ESC off if you ever need to. If the vehicle is in cruise control when the system begins to assist the driver maintain directional control of the vehicle, the ESC/TCS light will flash and the cruise control will automatically disengage. When road conditions allow you to use cruise again, you may re-engage the cruise control. See Cruise Control on page 9‑28.

The ESC OFF button is located on the instrument panel. The traction control system can be turned off or back on by pressing the ESC OFF button. To disable both traction control and ESC, press and hold the button briefly.

When the ESC system is turned off, the TRACTION CONTROL OFF message will appear, the STABILITRAK OFF message will appear, and the ESC OFF light will be on solid to warn the driver that both traction control and ESC are disabled. It is recommended to leave the system on for normal driving conditions, but it may be necessary to turn the system off if your vehicle is stuck in sand, mud, ice, or snow, and you want to “rock” your vehicle to attempt to free it. It may also be necessary to turn off the system when driving in extreme off-road conditions where high wheel spin is required. See If the Vehicle Is Stuck on page 9‑8.

This light will flash on the instrument panel cluster when the ESC system is both on and activated. You may also feel or hear the system working; this is normal. When the light is on solid and the SERVICE STABILITRAK message is displayed, the system will not assist the driver in maintaining directional control of the vehicle. Adjust your driving accordingly. See Ride Control System Messages on page 5‑30. The Electronic Stability Control (ESC) system is automatically enabled whenever you start your vehicle. To assist the driver with vehicle directional control, especially in slippery road

ESC may also turn off automatically if it determines that a problem exists with the system. The SERVICE STABILITRAK message and the ESC/TCS light will be on solid to warn the driver that ESC is disabled and requires service. If the problem does not clear after restarting the vehicle, you should see your dealer for service. See Ride Control System Messages on page 5‑30 for more information. Adding non‐dealer accessories can affect your vehicle performance. See Accessories and Modifications on page 10‑3 for more information.

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

{ WARNING

Cruise control can be dangerous where you cannot drive safely at a steady speed. So, do not use the cruise control on winding roads or in heavy traffic. Cruise control can be dangerous on slippery roads. On such roads, fast changes in tire traction can cause excessive wheel slip, and you could lose control. Do not use cruise control on slippery roads.

If your vehicle has the Traction Control System (TCS) and the cruise control is on, TCS will begin to limit wheel spin and the cruise control automatically turns off . See Traction Control System (TCS) on page 9‑25. When road conditions allow you to safely use it again, the cruise control can be turned back on.

The cruise control buttons are located on left side of the steering wheel.

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com. TOP TIER gasoline is only available in the U.S. and Canada.

To slow down in small amounts, press the SET– button briefly. Each time this is done, the vehicle goes about 1.6 km/h (1 mph) slower.

Passing Another Vehicle While Using Cruise Control Use the accelerator pedal to increase vehicle speed. When you take your foot off the pedal, the vehicle will slow down to the cruise speed you set earlier.

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 brakes are applied the cruise control will turn off.

knock, might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.

Gasoline Specifications At a minimum, gasoline should meet ASTM specification D 4814. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Fuel Additives on page 9‑32.

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 might fail a smog‐check test. See Malfunction Indicator Lamp on page 5‑14. 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 might not be covered by the vehicle warranty.

Fuels in Foreign Countries Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty.

Vehicles that have a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). See Fuel E85 (85% Ethanol) on page 9‑33. For all other vehicles, use only the unleaded gasoline described under Recommended Fuel on page 9‑31.

Recommended Fuel Use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, an audible knocking noise, commonly referred to as spark

To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.

Fuel Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, nothing should have to be added to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean and avoid problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by the auto companies. A list of

marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com. For customers who do not use TOP TIER Detergent Gasoline regularly, one bottle of GM Fuel System Treatment PLUS, added to the fuel tank at every engine oil change, can help clean deposits from fuel injectors and intake valves. GM Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 15% ethanol must not be used in vehicles that were not designed for those fuels.

Notice: This vehicle was not designed for fuel that contains methanol. 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 that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp might turn on. If this occurs, return to your dealer for service.

Notice: Some additives are not compatible with E85 fuel and can harm the vehicle's fuel system. Do not add anything to E85. Damage caused by additives would not be covered by the vehicle warranty. Notice: This vehicle was not designed for fuel that contains methanol. 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.

Fuel E85 (85% Ethanol) Vehicles that have a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). For all other vehicles, use only the unleaded gasoline described under Recommended Fuel on page 9‑31. We encourage the use of E85 in vehicles that are designed to use it. The ethanol in E85 is a “renewable” fuel, meaning it is made from renewable sources such as corn and other crops. Many service stations will not have an 85% ethanol fuel (E85) pump available. The U.S. Department of Energy has an alternative fuels website (www.afdc.energy.gov/afdc/ locator/stations/) that can help you find E85 fuel. Those stations that do have E85 should have a label indicating ethanol content. Do not use the fuel if the ethanol content is greater than 85%.

At a minimum, E85 should meet ASTM Specification D 5798 or CGSB Specification 3.512. Filling the tank with fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on. As the outside temperature approaches freezing, ethanol fuel distributors should supply winter grade ethanol, the same as with unleaded gasoline. The starting characteristics of E85
fuel make it unsuitable for use when temperatures fall below −18°C (0° F). In the range of −18°C (0°F) to 0° C (32°F), it may take more time to start the engine. E85 has less energy per liter (gallon) than gasoline, so you will need to refill the fuel tank more often when using E85 than when you are using gasoline. See Filling the Tank on page 9‑34.

WARNING (Continued)

. 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

The tethered fuel cap is located behind a hinged fuel door on the driver side of the vehicle. If the vehicle has E85 fuel capability, the fuel cap will be yellow and state that E85 or gasoline can be used. See Fuel E85 (85% Ethanol) on page 9‑33. To remove the fuel cap, turn it slowly counterclockwise. While refueling, hang the tethered fuel cap on the hook on the inside of the fuel door. Be careful not to spill fuel. Do not top off or overfill the tank and wait a few seconds after you have finished pumping before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care on page 10‑65. When replacing the fuel cap, turn it clockwise until it clicks. Make sure the cap is fully installed. The diagnostic system can determine if

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. See the following trailer towing information in this section:

For information on driving while towing a trailer, see “Driving Characteristics and Towing Tips.” For maximum vehicle and trailer weights, see “Trailer Towing.” For information on equipment to tow a trailer, see “Towing Equipment.”

For information on towing a disabled vehicle, see Towing the Vehicle on page 10‑63. For information on towing the vehicle behind another

vehicle such as a motor home, see Recreational Vehicle Towing on page 10‑63.

Driving Characteristics and Towing Tips

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

and local laws that apply specifically 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) trailer towing, do not drive over 80 km/h (50 mph) and do not make starts at full throttle. The vehicle can tow in D (Drive) but M (Manual Mode) is recommended. See Manual Mode on page 9‑22. Use a lower gear if the transmission shifts too often.

{ 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 on page 9‑19.

Towing a trailer requires a certain amount of experience. The combination you are driving is longer and not as responsive as the 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. Towing with a Stability Control System When towing, the sound of the stability control system might be heard. The system is reacting to the vehicle movement caused by the

trailer, which mainly occurs during cornering. This is normal when towing heavier trailers. 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 situations that require heavy braking and sudden turns. Passing More passing distance is needed when towing a trailer. Because the rig is longer, it is necessary to go 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 your 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.

Driving and Operating

9-37

Making Turns Notice: 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 so the trailer will not strike soft shoulders, curbs, road signs, trees or other objects. Use the turn signal well in advance and avoid jerky or sudden maneuvers. Turn Signals When Towing a Trailer The turn signal indicators on the instrument cluster flash whenever signaling a turn or lane change. Properly hooked up, the trailer lamps also flash, telling other drivers the vehicle is turning, changing lanes or stopping.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

Black plate (38,1)

9-38

Driving and Operating

When towing a trailer, the arrows on the instrument cluster flash for turns even if the bulbs on the trailer are burned out. 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 have to be used so much that they would get hot and no longer work well. The vehicle can tow in D (Drive). Use a lower gear if the transmission shifts too often. When towing at high altitude on steep uphill grades, engine coolant boils 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 vehicle could show signs similar to engine overheating.

To avoid this, let the engine run while parked, preferably on level ground, with the transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating on page 10‑14. 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 brake pedal 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

while you:

Start the engine. Shift into a gear. Release the parking brake.

2. Let up on the brake pedal. 3. Drive slowly until the trailer is

clear of the chocks.

4. 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 the Maintenance Schedule on page 11‑3. Things that are especially important in trailer operation are automatic transmission fluid, engine oil, axle lubricant, belts, cooling system and brake system. Inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight. Engine Cooling When Trailer Towing The cooling system may temporarily overheat during severe operating conditions. See Engine Overheating on page 10‑14.

Driving and Operating

9-39

Trailer Towing Before pulling a trailer, there are three important considerations that have to do with weight:

The weight of the trailer. The weight of the trailer tongue. The total weight on your vehicle's tires.

Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 454 kg (1,000 lbs). 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” later in this section.

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 on page 13‑3. Weight of the Trailer Tongue The tongue load (A) 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.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

Black plate (40,1)

9-40

Driving and Operating

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 on page 9‑9.

The trailer tongue (A) should weigh 10 to 15 percent of the total loaded trailer weight (B).

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 label. See Vehicle Load Limits on page 9‑9. Make sure not to go over the GVW limit for the vehicle, including the weight of the trailer tongue.

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 on page 9‑19.

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.

Chevrolet Impala Owner Manual - 2013 - crc - 8/27/12

Black plate (41,1)

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 Notice: Some electrical equipment can damage the vehicle or cause components to not work and would not be covered by the warranty. Always check with your dealer before adding electrical equipment.

Driving and Operating

9-41

Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating. The vehicle has an airbag system.

Engine Oil To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Always use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.

. Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.

. Change the engine oil at the

appropriate time. See Engine Oil Life System on page 10‑8.

. Always dispose of engine oil

properly. See “What to Do with Used Oil” in this section.

Checking Engine Oil It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a loop. See Engine Compartment Overview on page 10‑5 for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1.

If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.
