{ Warning

The RVC system does not display children, pedestrians, bicyclists, crossing traffic, animals, or any other object located outside the camera's field of view, below the bumper, or under the vehicle. Perceived distances may be different from actual distances. Do not back the vehicle using only the RVC screen. Failure to use proper care before backing may result in injury, death, or vehicle damage. Always check behind and around the vehicle before backing.

Parking Assist With Rear Park Assist (RPA), and if equipped with Front Park Assist (FPA), as the vehicle moves at speeds of less than 8 km/h (5 mph) the sensors on the bumpers may detect objects up to 2.5 m (8 ft) behind and 1.2 m (4 ft) in front of the

vehicle within a zone 25 cm (10 in) high off the ground and below bumper level. These detection distances may be shorter during warmer or humid weather. Blocked sensors will not detect objects and can also cause false detections. Keep the sensors clean of mud, dirt, snow, ice, and slush; and clean sensors after a car wash in freezing temperatures. { Warning

The parking assist system does not detect children, pedestrians, bicyclists, animals, or objects located below the bumper or that are too close or too far from the vehicle. It is not available at speeds greater than 8 km/h (5 mph). To prevent injury, death, or vehicle damage, even with parking assist, always check the area around the vehicle and check all mirrors before moving forward or backing.

The instrument cluster may have a parking assist display with bars that show “distance to object” and object location information for RPA, and on some vehicles, FPA. As the object gets closer, more bars light up and the bars change color from yellow to amber to red. When an object is first detected in the rear, one beep will be heard from the rear, or both sides of the Safety Alert Seat will pulse two times. When an object is very close (<0.6 m (2 ft) in the vehicle rear, or <0.3 m (1 ft) in the vehicle front), five beeps will sound from the front or rear depending where the object is detected, or both sides of the Safety Alert Seat will pulse five

times. Beeps for Front Parking Assist are higher pitched than for Rear Parking Assist.

Backing Warning and Rear Automatic Braking Vehicles with Adaptive Cruise Control (ACC) have the Backing Warning and Rear Automatic Braking (RAB) system. The Backing Warning part of this system can warn of rear objects when backing up at speeds greater than 8 km/h (5 mph). The Backing Warning System will beep once from the rear when an object is first detected, or pulse twice on both sides of the Safety Alert Seat. When the system detects a potential crash, beeps will be heard from the rear, or five pulses will be felt on both sides of the Safety Alert Seat. There may also be a brief, sharp application of the brakes.

{ Warning

The Backing Warning System only operates at speeds greater than 8 km/h (5 mph). It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle. In some situations, such as at higher backing speeds, there may not be enough time for the short, sharp application of the vehicle brake system to occur. To prevent injury, death, or vehicle damage, even with the Backing Warning System, always check the area around the vehicle and check all mirrors before backing.

When the vehicle is in R (Reverse) and if it is backing too fast to avoid a crash with a detected object directly behind the vehicle, the Rear Automatic Braking (RAB) system

may automatically brake hard to a stop to help avoid or reduce the harm caused by a backing crash.

{ Warning

Rear Automatic Braking may not avoid many types of backing crashes. Do not wait for the automatic braking to apply. This system is not designed to replace driver braking and only works in R (Reverse) when an object is detected directly behind the vehicle. It may not brake or stop in time to avoid a crash. It will not brake for objects when the vehicle is moving at very low speeds. It does not detect children, pedestrians, bicyclists, animals, or objects below the bumper or that are too close or too far from the vehicle.

Braking system. Before releasing the brakes, check the RVC screen and check the area around the vehicle to make sure it is safe to proceed.

Rear Cross Traffic Alert (RCTA) If equipped, RCTA displays a red warning triangle with a left or right pointing arrow on the RVC screen to warn of traffic coming from the left or right. This system detects objects coming from up to 20 m (65 ft) from the left or right side of the vehicle. When an object is detected, either three beeps sound from the left or right or three Safety Alert Seat pulses occur on the left or right side, depending on the direction of the detected vehicle. Use caution while backing up when towing a trailer, as the RCTA detection zones that extend out

from the back of the vehicle do not move further back when a trailer is towed. Turning the Features On or Off

The X button on the center stack is used to turn on or off the Front and Rear Parking Assist, Rear Cross Traffic Alert, Backing Warning, and Rear Automatic Braking system at the same time. The indicator light next to the button comes on when the features are on and turns off when the features have been disabled. Turn off parking assist and Rear Automatic Braking when towing a trailer.

To turn the rear parking assist symbols or guidance lines on or off, see “Rear Camera” under Vehicle Personalization on page 5-47. RCTA can also be turned on or off through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization on page 5-47. Automatic Parking Assist (APA) If equipped, APA searches for and steers the vehicle into parallel or perpendicular parking spots. When using APA, you must still shift gears, and control the brakes and accelerator. The Driver information Center (DIC) and audible beeps help to guide parking maneuvers.

{ Warning

APA does not apply the brakes. APA may not detect objects in the parking space, objects that are

Warning (Continued)

soft or narrow, objects high off the ground such as flatbed trucks, or objects below ground level such as large potholes. Always verify that the parking space is appropriate for parking a vehicle. APA does not respond to changes in the parking space, such as movement of an adjacent vehicle, or a person or object entering the parking space. APA does not detect or avoid traffic that is behind or alongside of the vehicle. Always be prepared to stop the vehicle during the parking maneuver.

The system is available when the vehicle speed is below 30 km/h (18 mph). Press the APA button, O, to enable the system to begin searching for a space that is

large enough to park in. The system cannot detect whether it is a legal parking space. If the vehicle is equipped with perpendicular parking mode, press and hold the APA button during the search process to switch the APA parking mode between perpendicular and parallel parking. APA searches for parking spaces to the right of the vehicle. To search for a parking space to the left, turn on the left turn signal.

After completely passing a large enough space bordered by two vehicles or other objects, an audible beep occurs and a red symbol displays in the DIC.

into a previously detected space. The APA system does not need service. If the vehicle exceeds 10 km/h (6 mph), APA is automatically disengaged and automatic steering will turn off. A DIC progress arrow displays the status of the parking maneuver. Depending on the space size, additional maneuvers may be required, and there will be additional instructions. When changing gears, allow the automatic steering to complete before continuing the parking maneuver. Upon successful completion of a maneuver, APA will beep and display a PARKING COMPLETE message. Place the vehicle in P (Park). APA may automatically disengage if:

The steering wheel is used by the driver. The maximum allowed speed is exceeded. There is a failure with the APA system.

. Electronic stability control or antilock brakes are activated.

. A high priority vehicle message

is displayed in the DIC.

. An incoming call is received through a connected phone. Disconnect the phone from the vehicle to prevent APA from disengaging.

To cancel APA, press the APA button again.

When the System Does Not Seem to Work Properly The APA system may require a short period of driving along curves to calibrate.

Assistance Systems for Driving If equipped, when driving the vehicle forward, Forward Collision Alert (FCA), Lane Departure Warning (LDW), Lane Keeping Assist (LKA), Side Blind Zone Alert (SBZA), Lane Change Alert (LCA),

APA will instruct the vehicle to stop once a large enough space is found. Follow the instructions in the DIC. When instructed to drive in reverse, shift to R (Reverse) to engage automatic steering. The steering wheel will briefly vibrate as a reminder to remove hands from the steering wheel. Check surroundings and continue braking or accelerating as needed, and be prepared to stop to avoid vehicles, pedestrians, or objects. If the vehicle is in R (Reverse), but does not steer into the expected space, this may be because the system is maneuvering the vehicle

and/or the Active Emergency Braking System can help to avoid a crash or reduce crash damage.

Forward Collision Alert (FCA) System If equipped, the FCA system may help to avoid or reduce the harm caused by front-end crashes. When approaching a vehicle ahead too quickly, FCA provides a flashing red alert on the windshield and rapidly beeps or pulses the Safety Alert Seat. FCA also lights an amber visual alert if following another vehicle much too closely. FCA detects vehicles within a distance of approximately 60 m (197 ft) and operates at speeds above 40 km/h (25 mph). If the vehicle has Adaptive Cruise Control (ACC), it can detect vehicles to distances of approximately 110 m (360 ft) and operates at all speeds. See Adaptive Cruise Control on page 9-37.

{ Warning

Detecting the Vehicle Ahead

FCA is a warning system and does not apply the brakes. When approaching a slower-moving or stopped vehicle ahead too rapidly, or when following a vehicle too closely, FCA may not provide a warning with enough time to help avoid a crash. FCA does not warn of pedestrians, animals, signs, guardrails, bridges, construction barrels, or other objects. Be ready to take action and apply the brakes. For more information, see Defensive Driving on page 9-3.

FCA can be disabled with the FCA steering wheel control, or if your vehicle is equipped with Adaptive Cruise Control (ACC), through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization on page 5-47.

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

{ Warning

FCA does not provide a warning to help avoid a crash, unless it detects a vehicle. FCA may not detect a vehicle ahead if the FCA sensor is blocked by dirt, snow,

or ice, or if the windshield is damaged. It may also not detect a vehicle on winding or hilly roads, or in conditions that can limit visibility such as fog, rain, or snow, or if the headlamps or windshield are not cleaned or in proper condition.

Continue to apply the brake pedal as needed. Cruise control may be disengaged when the Collision Alert occurs.

Tailgating Alert

The vehicle-ahead indicator will display amber when you are following a detected vehicle ahead much too closely.

Without Head-Up Display When your vehicle approaches another detected vehicle too rapidly, the red FCA display will flash on the windshield. Also, eight high-pitched beeps will sound from the front, or both sides of the Safety Alert Seat will pulse five times. When this Collision Alert occurs, the brake system may prepare for driver braking to occur more rapidly which can cause a brief, mild deceleration.

Driving and Operating

Selecting the Alert Timing

The Collision Alert control is on the steering wheel. Press [ to set the FCA timing to Far, Medium, Near, or on some vehicles, Off. The first button press shows the current setting on the DIC. Additional button presses will change this setting. The chosen setting will remain until it is changed and will affect the timing of both the Collision Alert and the Tailgating Alert features. The timing of both alerts will vary based on vehicle speed. The faster the vehicle speed, the farther away the

alert will occur. Consider traffic and weather conditions when selecting the alert timing. The range of selectable alert timing may not be appropriate for all drivers and driving conditions. If your vehicle is equipped with Adaptive Cruise Control (ACC), changing the FCA timing setting automatically changes the ACC following gap setting (Far, Medium, or Near). Unnecessary Alerts FCA may provide unnecessary alerts for turning vehicles, vehicles in other lanes, objects that are not vehicles, or shadows. These alerts are normal operation and the vehicle does not need service. Cleaning the System If the FCA system does not seem to operate properly, cleaning the outside of the windshield in front of the camera sensor on the back of the rearview mirror, and cleaning the

front of the vehicle where radar sensors are located, may correct the issue.

Active Emergency Braking System If the vehicle has Adaptive Cruise Control (ACC) it also has the Active Emergency Braking System, which includes Intelligent Brake Assist (IBA) and the Automatic Collision Preparation (ACP) System. These systems can provide a boost to braking or automatically brake the vehicle to help avoid or lessen the severity of crashes when driving in a forward gear. Intelligent Brake Assist (IBA) IBA may activate when the brake pedal is applied quickly by providing a boost to braking based on the speed of approach and distance to a vehicle ahead. Minor brake pedal pulsations or pedal movement during this time is normal and the brake pedal should

Cadillac CTS Owner Manual 7707478) - 2015 - crc - 5/6/14

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

Black plate (55,1)

continue to be applied as needed. IBA will automatically disengage only when the brake pedal is released.

{ Warning

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

Automatic Collision Preparation (ACP) System When driving in a forward gear above 4 km/h (2.5 mph), ACP may help reduce crash damage by applying the brakes. It has a detection range of approximately 60 m (197 ft). This front automatic braking can only occur if a vehicle is detected. This is shown by the FCA vehicle ahead indicator being lit. See Forward Collision Alert (FCA) System on page 9-52.

{ Warning

ACP is an emergency crash preparation feature and is not designed to avoid crashes. Do not rely on ACP to brake the vehicle. ACP may not:

. Respond to stopped vehicles,

pedestrians, or animals.

. Detect a vehicle ahead on

winding or hilly roads.

. Detect a stopped or

slow-moving vehicle or other object ahead.

. Detect a vehicle when

weather limits visibility, such as in fog, rain, or snow. In these situations, ACP sensor performance is limited.

(Continued)

Driving and Operating

9-55

Warning (Continued)

Complete attention is always required while driving, and you should be ready to take action and apply the brakes and/or steer the vehicle to avoid crashes.

Brake Preparation When quickly approaching a vehicle ahead, Brake Preparation reduces brake response time by having the brake system prepared for driver braking to occur more rapidly.

Automatic Braking If ACP detects it is about to crash with the vehicle you are following that is moving or has come to a stop, and the brakes have not been applied, it may automatically brake hard. This can help to reduce crash damage and it may even help to avoid some very low speed crashes. Automatic Braking may slow the vehicle to a complete stop to try to avoid a potential crash. If this

happens, Automatic Braking may engage the Electric Parking Brake (EPB) to hold the vehicle at a stop. To release the EPB, press the EPB button. A firm press of the accelerator pedal will also release Automatic Braking and the EPB.

{ Warning Automatic Braking may automatically brake the vehicle suddenly in situations where it is unexpected and undesired. It could respond to a turning vehicle ahead, guardrails, signs, and other non-moving objects. To override Automatic Braking, firmly press the accelerator pedal, if it is safe to do so.

Automatic Braking can be disabled or reduced through vehicle personalization. See the “Auto Collision Preparation” portion of “Collision/Detection Systems” under Vehicle Personalization on page 5-47.

{ Warning

Using the Automatic Collision Preparation System while towing a trailer could cause you to lose control of the vehicle and crash. Turn the system off when towing a trailer.

Side Blind Zone Alert (SBZA) If equipped, the SBZA system is a lane-changing aid that assists drivers with avoiding crashes that occur with vehicles in the side blind zone (or spot) areas. When the vehicle is moving forward, the left or right side mirror display will light up if a vehicle is detected in that blind zone. If the turn signal is activated and a vehicle is also detected on the same side, the display will flash as an extra warning not to change lanes. Since this system is part of

the Lane Change Alert system, read the entire Lane Change Alert section before using this feature.

Lane Change Alert If equipped, the LCA system is a lane-changing aid that assists drivers with avoiding lane change crashes that occur with vehicles in the side blind zone (or spot) areas or with vehicles rapidly approaching these areas from behind. The LCA warning display will light up in the corresponding outside side mirror and will flash if the turn signal is on.

{ Warning

LCA does not alert the driver to vehicles outside of the system detection zones, pedestrians, bicyclists, or animals. It may not provide alerts when changing lanes under all driving conditions. Failure to use proper care when changing lanes may result in

Drivers are also warned of vehicles rapidly approaching from up to 25 m (82 ft) behind the vehicle. How the System Works The LCA symbol lights up in the side mirrors when the system detects a vehicle in the next lane over that is in the side blind zone or rapidly approaching 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.

LCA can be disabled through vehicle personalization. See “Collision/Detection Systems” under Vehicle Personalization on page 5-47. 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 or when towing a trailer. The LCA detection zones that extend back from the side of the vehicle do not move further back when a trailer is towed. Use caution while changing lanes when towing a trailer. LCA may alert to objects attached to the vehicle, such as a trailer, bicycle,

or object extending out to either side of the vehicle. Attached objects may also interfere with the detection of vehicles. This is normal system operation; the vehicle does not need service. LCA may not always alert the driver to vehicles in the next lane over, especially in wet conditions or when driving on sharp curves. The system does not need to be serviced. The system may light up due to guardrails, signs, trees, shrubs, and other non-moving objects. This is normal system operation; the vehicle does not need service. LCA may not operate when the LCA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, or slush, or in heavy rainstorms. For cleaning instructions, see "Washing the Vehicle" under Exterior Care on page 10-69. 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 Lane Change Alert On option will not be available on the personalization menu. Radio Frequency Information See Radio Frequency Statement on page 13-12.

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)

Cadillac CTS Owner Manual 7707478) - 2015 - crc - 5/6/14

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

Black plate (59,1)

system, read the entire Lane Keep Assist (LKA) section before using this feature.

Lane Keep Assist (LKA) If equipped, 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).

Driving and Operating

Warning (Continued)

. 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 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 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. 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.

Driving and Operating

{ 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 on the center stack.

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. Move the steering wheel 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 the 2.0L L4 LTG turbo engine (VIN Code X), use premium unleaded gasoline meeting

Driving and Operating

9-61

ASTM specification D4814 with a posted octane rating of 91 or higher. Regular unleaded gasoline rated at 87 octane or higher can be used, but acceleration and fuel economy will be reduced, and an audible knocking noise may be heard. If this occurs, use a gasoline rated at 91 octane or higher as soon as possible. Otherwise, the engine could be damaged. If heavy knocking is heard when using gasoline with a 91 octane rating or higher, the engine needs service. If the vehicle has the 3.6L V6 LFX engine (VIN Code 3), 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. If the vehicle has the 3.6L V6 LF3
twin turbo engine (VIN Code 8), use premium unleaded gasoline meeting ASTM specification D4814 with a posted octane rating of 91 or higher.

If the octane is less than 91, damage to the engine may occur and may void the vehicle warranty. If heavy knocking is heard when using gasoline rated at 91 octane or higher, the engine needs service.

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

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 on page 5-19. 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 on page 9-61. 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

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

. Do not use Adaptive Cruise

Control when towing. The Automatic Collision Preparation System should be set to Off when towing. See Active Emergency Braking System on page 9-54. Turn off Parking Assist when towing.

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 on page 10-67. For towing the vehicle behind another vehicle such as a motor home, see Recreational Vehicle Towing on page 10-67.

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.

Driving and Operating

{ 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 9-22.

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. 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.

Vehicles can tow in D (Drive). Shift the transmission to a lower gear if the transmission shifts too often under heavy loads and/or hilly conditions. When towing at high altitude on steep uphill grades, consider the following: Engine coolant will boil at a lower temperature than at normal altitudes. If the engine is turned off immediately after towing at high altitude on steep uphill grades, the vehicle may show signs similar to engine overheating. To avoid this, let the engine run while parked, preferably on level ground, with the automatic transmission in P (Park) for a few minutes before turning the engine off. If the overheat warning comes on, see Engine Overheating on page 10-21.

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.

Caution (Continued)

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, 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.

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 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. It is a good idea to inspect these before and during the trip. Check periodically to see that all hitch nuts and bolts are tight.

Trailer Towing (With LFX Engine) Before pulling a trailer, three important considerations have to do with weight: . Weight of the trailer. . Weight of the trailer tongue.

Total weight on your vehicle's tires.

Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 454 kg (1,000 lb). But even that can be too heavy. It depends on how the rig is used. For example, speed, altitude, road grades, outside temperature, and

how much the vehicle is used to pull a trailer are all important. It can depend on any special equipment on the vehicle, and the amount of tongue weight the vehicle can carry. See “Weight of the Trailer Tongue” 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 (1) of any trailer is an important weight to measure because it affects the total gross weight of the vehicle. The Gross Vehicle Weight (GVW) includes the

Cadillac CTS Owner Manual 7707478) - 2015 - crc - 5/6/14

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

Black plate (69,1)

curb weight of the vehicle, any cargo carried in it, and the people who will be riding in the vehicle. If there are a lot of options, equipment, passengers, or cargo in the vehicle, it will reduce the tongue weight the vehicle can carry, which will also reduce the trailer weight the vehicle can tow. If towing a trailer, the tongue load must be added to the GVW because the vehicle will be carrying that weight, too. See Vehicle Load Limits on page 9-11.

Driving and Operating

9-69

The trailer tongue (1) should weigh 10 % of the total loaded trailer weight (2). After loading the trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they are not, adjustments might be made by moving some items around in the trailer. Total Weight on Your Vehicle's Tires Be sure the vehicle's tires are inflated to the upper limit for cold tires. These numbers can be found on the Tire and Loading Information label. See Vehicle Load Limits on page 9-11. Make sure not to go over the GVW limit for the vehicle, including the weight of the trailer tongue.

Trailer Towing (With LTG or LF3 Engine) The vehicle is neither designed nor intended to tow a trailer.

Towing Equipment

Hitches Use the correct hitch equipment. See your dealer or a hitch dealer for assistance.

The rear bumper on the vehicle is not intended for hitches. Do not attach rental hitches or other bumper-type hitches to it. Use only a frame-mounted hitch that does not attach to the bumper. . Will any holes be made in the body of the vehicle when the trailer hitch is installed? If so, seal the holes when the hitch is removed. If the holes are not sealed, dirt, water, and deadly carbon monoxide (CO) from the exhaust can get into the vehicle. See Engine Exhaust on page 9-22.

Safety Chains Always attach chains between the vehicle and the trailer. Cross the safety chains under the tongue of

Cadillac CTS Owner Manual 7707478) - 2015 - crc - 5/6/14

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

Black plate (70,1)

9-70

Driving and Operating

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

Conversions and Add-Ons

Add-On Electrical Equipment

{ Caution

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.

Add-on equipment can drain the vehicle's 12-volt battery, even if the vehicle is not operating. The vehicle has an airbag system. Before attempting to add anything electrical to the vehicle, see Servicing the Airbag-Equipped Vehicle on page 3-33 and Adding Equipment to the Airbag-Equipped Vehicle on page 3-33.
