{ 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
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 0 173. 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
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
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 0 391. 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 0 427.
Lane Departure Warning (LDW) If equipped, LDW may help avoid crashes due to unintentional lane departures. It may provide a warning if the vehicle is crossing a detected lane marking without using a turn signal in the lane departure direction. Since this system is part of the Lane Keep Assist (LKA) system, read the entire LKA section before using this feature.
Driving and Operating
289
Lane Keep Assist (LKA) If equipped (1500 series vehicles), LKA may help avoid crashes due to unintentional lane departures. It may assist by gently turning the steering wheel if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide a Lane Departure Warning (LDW) system alert as the lane marking is crossed. The LKA system will not assist or provide an LDW alert if it detects that you are actively steering. Override LKA by turning the steering wheel. LKA uses a camera to detect lane markings between 60 km/h (37 mph) and 180 km/h (112 mph). { Warning The LKA system does not continuously steer the vehicle. It may not keep the vehicle in the lane or give a Lane Departure Warning (LDW) alert, even if a lane marking is detected.

Warning (Continued)
Warning (Continued)
The LKA and LDW systems may not:
. Provide an alert or enough
steering assist to avoid a lane departure or 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 LKA only detects lane markings on one side of the road, it will only assist or provide an LDW alert when approaching the lane on the side where it has detected a lane marking. Even with LKA and LDW, you must steer the
(Continued)
vehicle. Always keep your attention on the road and 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 LKA in bad weather conditions.
{ Warning
Using LKA while towing a trailer or on slippery roads could cause loss of control of the vehicle and a crash. Turn the system off.
How the System Works The LKA camera sensor is on the windshield ahead of the rearview mirror. To turn LKA on and off, press A to the left of the steering wheel.
When on, A is green if LKA is available to assist and provide LDW alerts. It may assist by gently turning the steering wheel and display A as amber if the vehicle approaches a detected lane marking without using a turn signal in that direction. It may also provide an LDW alert by flashing A amber as the lane marking is crossed. 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. The LKA system does not continuously steer the vehicle. If LKA does not detect active driver steering, an alert and chime may be provided. Steer the vehicle to dismiss.

When the System Does Not Seem to Work Properly The system performance may be affected by: . Close vehicles ahead. . Sudden lighting changes, such
as when driving through tunnels.
. Banked roads. . Roads with poor lane markings,
such as two-lane roads.
If the LKA system is not functioning properly when lane markings are clearly visible, cleaning the windshield may help. LKA assistance and/or 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 LKA 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 label on the fuel door, E85 or FlexFuel can be used in the vehicle. See E85 or FlexFuel 0 293.
Driving and Operating
291
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
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
292
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) 0 146. 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 0 291. 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.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
Do not use additives with E85 or FlexFuel.
E85 or FlexFuel For a heavy-duty Suburban, see the Suburban Heavy-Duty Package supplement. Vehicles with fuel caps marked as “E85” or FlexFuel can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). All other vehicles should use only the unleaded gasoline as described in Fuel 0 291. The use of E85 or FlexFuel is encouraged when the vehicle is designed to use it. E85 or FlexFuel is made from renewable sources. Many fuel stations will not have an 85% ethanol fuel (E85) pump available. Those stations that do have E85 should have a label indicating the FlexFuel ethanol content. Do not use the fuel if the ethanol content is greater than 85%.
Driving and Operating
293
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 0 293.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

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 0 385. For towing the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing 0 385.
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.
. Turn off Parking Assist when
towing.
. The Front Automatic Braking System should be set to Off when towing. See Front Automatic Braking (FAB) System 0 286.
{ 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 0 254.
Towing a trailer requires a certain amount of experience. The combination you are driving is longer and not as responsive as the
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
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
297
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, use the Tow/Haul Mode to prevent damage to the engine or transmission. See Tow/ Haul Mode 0 259. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at

298
Driving and Operating
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 may 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 0 326. 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 0 401. 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.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/28/15
Trailer Towing Do not tow a trailer during break-in. See New Vehicle Break-In 0 244. Before towing a trailer, see "Hands-Free Operation" under Liftgate 0 47.
{ Warning
The driver can lose control when pulling a trailer if the correct equipment is not used or the vehicle is not driven properly. For example, if the trailer is too heavy, the brakes may not work well — or even at all. The driver and passengers could be seriously injured. The vehicle may also be damaged; the resulting repairs would not be covered by the vehicle warranty. Pull a trailer only if all the steps in this section have been followed. Ask your dealer for advice and information about towing a trailer with the vehicle.
Caution
Pulling a trailer improperly can damage the vehicle and result in costly repairs not covered by the vehicle warranty. To pull a trailer correctly, follow the advice in this section and see your dealer for important information about towing a trailer with the vehicle.
To identify the trailering capacity of the vehicle, read the information in “Weight of the Trailer” following. Trailering is different than just driving the vehicle by itself. Trailering means changes in handling, acceleration, braking, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. The following information has many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of
Driving and Operating
299
your passengers. So please read this section carefully before pulling a trailer. Weight of the Trailer How heavy can a trailer safely be? It depends on how the rig is used. 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. Trailer Weight Rating (TWR) is calculated assuming the tow vehicle has only the driver and all required trailering equipment. Weight of additional optional equipment, passengers, and cargo in the tow vehicle must be subtracted from the trailer weight rating. Use the following chart to determine how much the vehicle can weigh, based upon the vehicle model and options.

*The Gross Combination Weight Rating (GCWR) is the total allowable weight of the completely loaded vehicle and trailer including any passengers, cargo, equipment, and conversions. The GCWR for the vehicle should not be exceeded.
Ask your dealer for trailering information or advice.
Weight of the Trailer Tongue The tongue load (1) of any trailer is very important because it is also part of the vehicle weight. 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 as well as trailer tongue weight. Vehicle options, equipment, passengers, and cargo in the
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
vehicle reduce the amount of tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow. See Vehicle Load Limits 0 240 for more information about the vehicle's maximum load capacity.

Do not exceed the maximum allowable tongue weight for the vehicle. Choose the shortest hitch extension that will position the hitch ball closest to the vehicle. This will help reduce the effect of trailer tongue weight on the rear axle. Trailer rating may be limited by the vehicle's ability to carry tongue weight. Tongue weight cannot cause the vehicle to exceed the GVWR (Gross Vehicle Weight Rating) or the RGAWR (Rear Gross Axle Weight Rating). See “Total Weight on the Vehicle's Tires” following. 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.
If a cargo carrier is used in the trailer hitch receiver, choose a carrier that positions the load as close to the vehicle as possible. Make sure the total weight, including the carrier, is no more than half of the maximum allowable tongue weight for the vehicle or 227
kg (500 lb), whichever is less. Total Weight on the Vehicle's Tires Be sure the vehicle's tires are inflated to the inflation pressures found on the Certification label on the center pillar or see Vehicle Load Limits 0 240. Make sure not to exceed the GVWR limit for the vehicle, or the RGAWR, with the tow vehicle and trailer fully loaded for the trip including the weight of the trailer tongue. If using a weight-distributing hitch, make sureTrailer tongue weight (1) should be 10 % to 15 % of the loaded trailer weight (2) up to the maximums for vehicle series and hitch type.

Driving and Operating
not to exceed the RGAWR before applying the weight distribution spring bars. Weight of the Trailering Combination It is important that the combination of the tow vehicle and trailer does not exceed any of its weight ratings — GCWR, GVWR, RGAWR, Trailer Weight Rating, or Tongue Weight. The only way to be sure it is not exceeding any of these ratings is to weigh the tow vehicle and trailer combination, fully loaded for the trip, getting individual weights for each of these items.
Towing Equipment
Hitches The correct hitch equipment helps maintain combination control. Most small-to-medium trailers can be towed with a weight-carrying hitch which simply features a coupler latched to the hitch ball. Larger trailers may require a weight-distributing hitch that uses spring bars to distribute the trailer
tongue weight among the two vehicle and trailer axles. See “Weight of the Trailer Tongue” in Trailer Towing 0 299 for rating limits with various hitch types. Consider using sway controls with any trailer. Ask a trailering professional about sway controls or refer to the trailer manufacturer's recommendations and instructions. Weight-Distributing Hitch Adjustment
1. Front of Vehicle 2. Body to Ground Distance
When using a weight-distributing hitch, the spring bars should be adjusted so the distance (2) is the same after coupling the trailer to the tow vehicle and adjusting the hitch. 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. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. If the trailer being towed weighs up to 2 271 kg (5,000 lb) with a factory-installed step bumper, safety chains may be attached to the attaching points on the bumper, otherwise, safety chains should be attached to holes on the trailer hitch platform. Always leave just enough slack so the combination can turn. Never allow safety chains to drag on the ground.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
Trailer Brakes A loaded trailer that weighs more than 900 kg (2,000 lb) needs to have its own brake system that is adequate for the weight of the trailer. Be sure to read and follow the instructions for the trailer brakes so they are installed, adjusted, and maintained properly. Since the vehicle is equipped with StabiliTrak, the trailer brakes cannot tap into the vehicle's hydraulic system. Trailer Wiring Harness The seven-pin trailer connector is mounted in the bumper. This connector can be plugged into a seven-pin universal heavy-duty trailer connector available through your dealer. The seven-wire harness contains the following trailer circuits: . Yellow: Left Stop/Turn Signal . Green/Violet: Right Stop/Turn
Signal
. Brown: Taillamps
. White: Ground . Light Green: Back-up Lamps . Red/Green: Battery Feed . Dark Blue: Trailer Brake If charging a remote (non-vehicle) battery, press the Tow/Haul mode button at the end of the shift lever. This will boost the vehicle system voltage and properly charge the battery. If the trailer is too light for Tow/Haul mode, turn on the headlamps as a second way to boost the vehicle system and charge the battery. Electric Brake Control Wiring Provisions These wiring provisions are included with the vehicle as part of the trailer wiring package. These provisions are for an electric brake controller. The harness should be installed by your dealer or a qualified service center.

Driving and Operating
Tow/Haul is a feature that assists when pulling a heavy trailer or a large or heavy load. See Tow/Haul Mode 0 259. Tow/Haul is designed to be most effective when the vehicle and trailer combined weight is at least 75 percent of the vehicle's Gross Combined Weight Rating (GCWR). See “Weight of the Trailer” under Trailer Towing 0 299. Tow/Haul is most useful under the following driving conditions: . When pulling a heavy trailer or a
large or heavy load through rolling terrain.
. When pulling a heavy trailer or a
large or heavy load in stop-and-go traffic.
. When pulling a heavy trailer or a
large or heavy load in busy parking lots where improved low speed control of the vehicle is desired.
Operating the vehicle in Tow/Haul when lightly loaded or with no trailer at all will not cause damage. However, there is no benefit to the
selection of Tow/Haul when the vehicle is unloaded. Such a selection when unloaded may result in unpleasant engine and transmission driving characteristics and reduced fuel economy. Tow/ Haul is recommended only when pulling a heavy trailer or a large or heavy load. Integrated Trailer Brake Control System
The vehicle may have an Integrated Trailer Brake Control (ITBC) system for use with electric trailer brakes or most electric-over-hydraulic trailer brakes. This symbol is on the Trailer Brake Control Panel on vehicles with an ITBC system. The power output to the trailer brakes is based on the amount of brake pressure being applied by the vehicle’s brake
system, and on the type of trailer brakes detected. This available power output to the trailer brakes can be adjusted to a wide range of trailering situations. The ITBC system is integrated with the vehicle’s brake, antilock brake, and StabiliTrak systems. In trailering conditions that cause the vehicle’s antilock brake or StabiliTrak systems to activate, power sent to the trailer's brakes will be automatically adjusted to minimize trailer wheel lock-up. This does not imply that the trailer has StabiliTrak. If the vehicle’s brake, antilock brake, or StabiliTrak systems are not functioning properly, the ITBC system may not be fully functional or may not function at all. Make sure all of these systems are fully operational to ensure full functionality of the ITBC system. The ITBC system is powered through the vehicle's electrical system. Turning the ignition off will also turn off the ITBC system. The ITBC system is fully functional only when the ignition is in ON/RUN.

TRAILER GAIN: This setting can be adjusted from 0.0 to 10.0 with either a trailer connected or disconnected. To adjust the Trailer Gain, press one of the Trailer Gain adjustment buttons. Press and hold a gain button to continuously adjust the Trailer Gain. To turn the output to the trailer off, adjust the Trailer Gain setting to 0.0 (zero). TRAILER OUTPUT: Displays any time a trailer with electric brakes is connected. Output to the trailer brakes is based on the amount of vehicle braking present and relative to the Trailer Gain setting. Output is displayed from 0 to 100% for each gain setting. The Trailer Output will indicate “- - - - - -” on the Trailer Brake Display Page whenever the following occur: . No trailer is connected. . A trailer without electric brakes is connected (no DIC message displayed).
. A trailer with electric brakes has
become disconnected (a CHECK TRAILER WIRING message will also display on the DIC).
. There is a fault present in the wiring to the trailer brakes (a CHECK TRAILER WIRING message will also display on the DIC).
. The ITBC system is not working
due to a fault (a SERVICE TRAILER BRAKE SYSTEM message will also display in the DIC).
Manual Trailer Brake Apply The Manual Trailer Brake Apply Lever is used to apply the trailer’s electric brakes independent of the vehicle’s brakes. Sliding the lever to the left will apply only the trailer brakes. Use this lever to adjust Trailer Gain to properly adjust the power output to the trailer brakes. The trailer's and the vehicle's brake lamps will come on when either vehicle brakes or manual trailer brakes are applied.
Trailer Gain Adjustment Procedure Trailer Gain should be set for a specific trailering condition and must be adjusted any time vehicle loading, trailer loading, or road surface conditions change. { Warning Trailer brakes that are over-gained or under-gained may not stop the vehicle and the trailer as intended and can result in a crash. Always follow the instructions to set the Trailer Gain for the proper trailer stopping performance.
Use the following to adjust Trailer Gain for each towing condition: 1. Drive the vehicle with the trailer
attached on a level road surface representative of the towing condition and free of traffic at about 32 to 40 km/h (20 to 25 mph) and fully apply the Manual Trailer Brake apply lever.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
Adjusting Trailer Gain at speeds lower than 32 to 40 km/h (20 to 25 mph) may result in an incorrect gain setting.
2. Adjust the Trailer Gain, using
the Trailer Gain adjustment buttons, to just below the point of trailer wheel lock-up, indicated by trailer wheel squeal or tire smoke when a trailer wheel locks. Trailer wheel lock-up may not occur if towing a heavily loaded trailer. In this case, adjust the Trailer Gain to the highest allowable setting for the towing condition.
3. Readjust Trailer Gain any time vehicle loading, trailer loading, or road surface conditions change or if trailer wheel lock-up is noticed at any time while towing.
Other ITBC-Related DIC Messages In addition to displaying TRAILER GAIN and OUTPUT through the DIC, trailer connection and ITBC system status are displayed on the DIC. TRAILER CONNECTED: This message will briefly display when a trailer with electric brakes is first connected to the vehicle. This message will automatically turn off in about 10 seconds. This message can be acknowledged before it automatically turns off. CHECK TRAILER WIRING: This message will display if: . The ITBC system first
determines connection to a trailer with electric brakes and then the trailer harness becomes disconnected from the vehicle. If the disconnect occurs while the vehicle is stationary, this message will automatically turn off in about 30 seconds. This message will also turn off if it is acknowledged or if the trailer harness is reconnected.
Driving and Operating
307
If the disconnect occurs while the vehicle is moving, this message will continue until the ignition is turned off. This message will also turn off if it is acknowledged or if the trailer harness is reconnected.
. There is an electrical fault in the wiring to the trailer brakes. This message will continue as long as there is an electrical fault in the trailer wiring. This message will also turn off if it is acknowledged.
To determine if the electrical fault is on the vehicle side or trailer side of the trailer wiring harness connection: 1. Disconnect the trailer wiring
harness from the vehicle.
2. Turn the ignition off. 3. Wait 10 seconds, then turn the
4.
ignition back to RUN. If the CHECK TRAILER WIRING message reappears, the electrical fault is on the vehicle side.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/20/15
308
Driving and Operating
If the CHECK TRAILER WIRING message only reappears when connecting the trailer wiring harness to the vehicle, the electrical fault is on the trailer side.
SERVICE TRAILER BRAKE SYSTEM: This message will display when there is a problem with the ITBC system. If this message continues over multiple ignition cycles, there is a problem with the ITBC system. Have the vehicle serviced. If either the CHECK TRAILER WIRING or SERVICE TRAILER BRAKE SYSTEM message displays while driving, the ITBC system may not be fully functional or may not function at all. When traffic conditions allow, carefully pull the vehicle over to the side of the road and turn the ignition off. Check the wiring connection to the trailer and turn the ignition back on. If either of these messages continues, either the vehicle or trailer needs service.
A GM dealer may be able to diagnose and repair problems with the trailer. However, any diagnosis and repair of the trailer is not covered under the vehicle warranty. Contact your trailer dealer for assistance with trailer repairs and trailer warranty information.
Trailer Sway Control (TSC) Vehicles with StabiliTrak have a TSC feature. Trailer sway is unintended side-to-side motion of a trailer while being towed. If the vehicle is towing a trailer and the TSC detects that sway is increasing, the vehicle brakes are selectively applied at each wheel, to help reduce excessive trailer sway. If the vehicle is equipped with the Integrated Trailer Brake Control (ITBC) system, and the trailer has the electric actuated brake system, StabiliTrak may also apply the trailer brakes. If TSC is enabled, the Traction Control System (TCS)/StabiliTrak warning light will flash on the
instrument cluster. Vehicle speed must be reduced. If trailer sway continues, StabiliTrak can reduce engine torque to help slow the vehicle. See Traction Control/ Electronic Stability Control 0 267.
{ Warning
Even if the vehicle is equipped with TSC, trailer sway could result in loss of control and the vehicle could crash. If excessive trailer sway is detected, slow down to a safe speed. Check the trailer and vehicle to help correct possible causes. These could include an improperly or overloaded trailer, unrestrained cargo, improper trailer hitch configuration, excessive vehicle-trailer speed, or improperly inflated or incorrect vehicle or trailer tires. See Towing Equipment 0 302 for trailer ratings and hitch setup recommendations.

Engine Oil For a heavy-duty Suburban, see the “Engine Oil” section in the Suburban Heavy-Duty Package supplement. 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.
Vehicle Care
315
. 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 0 317.
. Always dispose of engine oil
properly. See “What to Do with Used Oil” in this section.
Checking Engine Oil If equipped, the ENGINE OIL LOW ADD OIL message displays when the engine oil level may be too low. See Engine Oil Messages 0 164. Check the oil level before filling to the recommended level. If the oil is not low and this message remains on, see your dealer. It is also 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 0 314 for the location of the engine oil dipstick.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/19/15
316
Vehicle Care
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.
{ Warning
The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.
2. Pull out the dipstick and wipe it
with a clean paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications 0 415.
Caution
Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level
(Continued)
Caution (Continued)
gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil.
See Engine Compartment Overview 0 314 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants 0 410.
Specification Ask for and use engine oils that meet the dexos1™ specification.
Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-9159366) - 2016 - crc - 5/19/15
Engine oils that have been approved by GM as meeting the dexos1 specification are marked with the dexos1 approved logo. See www.gmdexos.com.
Caution
Failure to use the recommended engine oil can result in engine damage not covered by the vehicle warranty. Check with your dealer or service provider on whether the oil is approved to the dexos1 specification.
Viscosity Grade Use SAE 0W-20 viscosity grade engine oil. When selecting an oil of the appropriate viscosity grade, always select an oil of the correct
specification. See “Specification” earlier in this section for more information. Engine Oil Additives/Engine Oil Flushes
