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

If the Vehicle Is Stuck Slowly and cautiously spin the wheels to free the vehicle when stuck in sand, mud, ice, or snow. If stuck too severely for the traction system to free the vehicle, turn the traction system off and use the rocking method. See Traction Control System (TCS) on page 9‑36.

Driving and Operating

{ WARNING

If the vehicle's tires spin at high speed, they can explode, and you or others could be injured. The vehicle can overheat, causing an engine compartment fire or other damage. Spin the wheels as little as possible and avoid going above 56 km/h (35 mph).

Rocking the Vehicle to Get it Out Turn the steering wheel left and right to clear the area around the front wheels. Turn off any traction system. Shift back and forth between R (Reverse) and a low forward gear, spinning the wheels as little as possible. To prevent transmission wear, wait until the wheels stop spinning before shifting gears. Release the accelerator pedal while shifting, and press lightly on the accelerator pedal when the transmission is in gear.

Slowly spinning the wheels in the forward and reverse directions causes a rocking motion that could free the vehicle. If that does not get the vehicle out after a few tries, it might need to be towed out. If the vehicle does need to be towed out, see Towing the Vehicle on page 10‑105.

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

{ WARNING

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

Tire and Loading Information Label

Label Example

A vehicle-specific Tire and Loading Information label is attached to the vehicle's center pillar (B-pillar). With the driver door open, you will find the label attached near the door lock post. The Tire and Loading Information label shows the number of occupant seating

positions (1), and the maximum vehicle capacity weight (2) in kilograms and pounds. The Tire and Loading Information label also shows the tire size of the original equipment tires (3) and the recommended cold tire inflation pressures (4). For more information on tires and inflation see Tires on page 10‑59 and Tire Pressure on page 10‑67. There is also important loading information on the Certification label. It tells you the Gross Vehicle Weight Rating (GVWR) and the Gross Axle Weight Rating (GAWR) for the front and rear axle. See “Certification Label” later in this section.

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

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

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

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

4. The resulting figure equals

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

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Black plate (12,1)

9-12

Driving and Operating

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

5. Determine the combined

6.

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

See Trailer Towing (CTS-V and Coupe) on page 9‑56 or Trailer Towing (Except CTS-V and Coupe) on page 9‑56 for important information on towing a trailer, towing safety rules and trailering tips.

Label Example

A vehicle-specific Certification label is attached to either the driver door edge or the lower center pillar on the driver side of the vehicle. The label tells the gross weight capacity of the vehicle, called the Gross Vehicle Weight Rating (GVWR). The

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

Starting and Operating

New Vehicle Break-In Follow these recommended guidelines during the first 2 414 km (1,500 miles) of driving this vehicle. Parts have a break-in period and performance will be better in the long run. For the first 2 414 km (1,500 miles): . Avoid full throttle starts and

abrupt stops.

. Do not exceed 4,000

engine rpm.

. Avoid driving at any one

constant speed, fast or slow.

. Avoid downshifting to brake or

slow the vehicle when the engine speed will exceed 4000 rpm.

. Do not let the engine labor. Never lug the engine in high gear at low speeds. With a

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Black plate (15,1)

manual transmission, shift to the next lower gear. This rule applies at all times, not just during the break-in period. . Do not participate in track

events, sport driving schools, or similar activities during this break–in period.

. Check engine oil with every

refueling and add if necessary. Oil and fuel consumption may be higher than normal during the first 2 414 km (1,500 miles). To break in new tires, drive at moderate speeds and avoid hard cornering for the first 322 km (200 miles). New tires do not have maximum traction and may tend to slip.

. New brake linings also need a break–in period. Avoid making hard stops during the first 322 km (200 miles). This is recommended every time brake linings are replaced.

Ignition Positions (Keyless Access) The ignition control knob can be turned to four different positions. To shift out of P (Park), the ignition must be in ON/RUN or ACC/ ACCESSORY and the regular brake pedal must be applied.

Using a tool to force the ignition control knob from its cylinder could damage it.

Make sure the keyless access transmitter is inside the vehicle when trying to turn the ignition control knob. 1 (STOPPING THE ENGINE/LOCK/ OFF): When the vehicle is stopped, turn the ignition switch to LOCK/ OFF to turn the engine off. Retained Accessory Power (RAP) will remain active. See Retained Accessory Power (RAP) on page 9‑21. The ignition control knob cannot be removed from the vehicle. The keyless access transmitter must be inside the vehicle to start the engine. This position locks the ignition and shift lever on automatic transmission vehicles, and the ignition and steering wheel on manual transmission vehicles. Do not turn the engine off when the vehicle is moving. This will cause a loss of power assist in the brake and steering systems and disable the airbags.

Driving and Operating

If the vehicle must be shut off in an emergency: 1. Brake using a firm and steady

pressure. Do not pump the brakes repeatedly. This may deplete power assist, requiring increased brake pedal force.

2. Shift the vehicle to neutral. This can be done while the vehicle is moving. After shifting to neutral, firmly apply the brakes and steer the vehicle to a safe location.

3. Come to a complete stop. Shift

to P (Park) with an automatic transmission, or Neutral with a manual transmission. Turn the ignition to LOCK/OFF.

4. Set the parking brake. See Parking Brake (Electric) on page 9‑33 or Parking Brake (Manual) on page 9‑33.

{ WARNING

Turning off the vehicle while moving may cause loss of power assist in the brake and steering systems and disable the airbags. While driving, only shut the vehicle off in an emergency.

If the vehicle cannot be pulled over, and must be shut off while driving, switch the ignition to ACC/ ACCESSORY. 2 (ACC/ACCESSORY): This position allows you to use things like the radio and the windshield wipers when the engine is off. This position will allow you to turn off the engine. 3 (ON/RUN): This position is for driving. It is the position the ignition switch returns to after the engine starts, and the control knob is released. This position can also be used for service and diagnostics, and to verify the proper operation of

the malfunction indicator lamp as may be required for emission inspection purposes. If you need to shift the transmission out of P (Park), the ignition control knob has to be in ACC/ ACCESSORY or ON/RUN. The battery could be drained if you leave the ignition in the ACC/ ACCESSORY or ON/RUN position with the engine off. You may not be able to start the vehicle if the battery is allowed to drain for an extended period of time. 4 (START): This position starts the engine.

To shift the transmission out of P (Park), the ignition key has to be in ACC/ACCESSORY or ON/RUN. The battery could be drained if the key is left in the ACC/ACCESSORY or ON/RUN position with the engine off. The vehicle might not start if the battery is allowed to drain for an extended period of time. 4 (START): This position starts the engine. When the engine starts, release the key. The ignition switch returns to ON/RUN for driving. A warning tone will sound when the driver door is opened, the ignition is in ACC/ACCESSORY or LOCK/ OFF, and the key is in the ignition.

Key Lock Release

Vehicles with an automatic transmission are equipped with an electronic key lock release system. The key lock release is designed to prevent ignition key removal unless the shift lever is in P (Park). The key lock release is always functional except in the case of an uncharged or low voltage (less than 9-volt) battery. If the vehicle has an uncharged battery or a battery with

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Black plate (19,1)

low voltage, try charging or jump starting the battery. See Jump Starting on page 10‑101. If charging or jump starting the battery does not work, locate the hole below the ignition lock. Insert a flat bladed tool or another key from the key chain into the opening. When the lever can be felt, actuate the lever away from the driver, and remove the key from the ignition.

Starting the Engine Place the transmission in the proper gear. If the vehicle has the keyless access system, the keyless access transmitter must be authenticated in order for the ignition control knob to turn. The transmitter can be authenticated either by putting your foot on the brake pedal or by pushing the ignition control knob in.

Driving and Operating

9-19

Automatic Transmission Move the shift lever to P (Park) or N (Neutral). The engine will not start in any other position. To restart the engine when the vehicle is already moving, use N (Neutral) only. If the vehicle has the keyless access system, your foot must be on the brake pedal to start the engine. To rotate the ignition control knob, put your foot on the brake pedal and turn the ignition control knob to the START position. If the ignition control knob does not turn, try pushing the knob in and turning again. When the engine begins cranking, let go of the ignition control knob, it will return to the ON/ RUN position. If the transmitter is not in the vehicle or something is interfering with the transmitter, the Driver Information Center (DIC) will display ELECTRONIC KEY NOT DETECTED. See Driver Information Center (DIC) on page 5‑27 for more information.

If the battery in the keyless access transmitter needs replacing, the DIC displays REPLACE BATTERY IN REMOTE KEY. The vehicle can still be driven. See “Battery Replacement” under Remote Keyless Entry (RKE) System Operation (Key Access) on page 2‑4 or Remote Keyless Entry (RKE) System Operation (Keyless Access) on page 2‑6 for more information. Notice: Do not try to shift to P (Park) if the vehicle is moving. If you do, you could damage the transmission. Shift to P (Park) only when the vehicle is stopped.

Manual Transmission The shift lever should be in neutral position and the parking brake engaged. Hold the clutch pedal down to the floor and start the engine. The vehicle will not start if the clutch pedal is not all the way down.

Driving and Operating

Starting Procedure 1. With your foot off the accelerator

pedal, turn the ignition key to START. If the vehicle has the keyless access system, push the ignition control knob in and rotate the knob to the START position. When the engine starts, let go of the ignition. The idle speed will go down as your engine gets warm. Do not race the engine immediately after starting it. Operate the engine and transmission gently to allow the oil to warm up and lubricate all moving parts. The vehicle has a Computer-Controlled Cranking System. This feature assists in starting the engine and protects components. If the ignition key is turned to the START position, and then released when the engine begins cranking, the engine will continue cranking for a few seconds or until the vehicle starts. If the engine does not start and the key is held in

START for many seconds, cranking will be stopped after 15 seconds to prevent cranking motor damage. To prevent gear damage, this system also prevents cranking if the engine is already running. Engine cranking can be stopped by turning the ignition switch to ACC/ACCESSORY or LOCK/OFF. When first starting the vehicle, the engine idle speed will be elevated to allow the catalytic converter, an emissions control device, to quickly reach operating temperature. After approximately 20 seconds, the engine will begin to transition to its normal, quieter idle speed, which can vary depending on the temperature. This is normal operation.

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 0°F or −18°C), 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, do the same thing. 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.

Engine Coolant Heater Vehicles with the engine coolant heater can use this option in cold weather conditions at or below −18°C (0°F) for easier starting and better fuel economy during engine warm-up. Plug in the coolant heater at least four hours before starting your vehicle. An internal thermostat in the plug-end of the cord may exist which will prevent engine coolant heater operation at temperatures above −18°C (0°F). To Use the Engine Coolant Heater 1. Turn off the engine. 2. Open the hood and unwrap the electrical cord. The cord is near the driver side strut tower. Remove the plastic cap to access the plug.

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 three-prong 110-volt AC outlet. If the cord will not reach, use a heavy-duty three-prong extension cord rated for at least 15 amps.

4. Before starting the engine, be

sure to unplug and store the cord as it was before to keep it away from moving engine parts. If you do not, it could be damaged.

Contact your dealer for information on how long to use the heater in your particular area.

Shifting Into Park Use this procedure to shift into P (Park): 1. Hold the brake pedal down and

set the parking brake. See Parking Brake (Electric) on page 9‑33 or Parking Brake (Manual) on page 9‑33 for more information.

2. Move the shift lever into P (Park)

by holding in the button on the shift lever and pushing the lever all the way toward the front of the vehicle.

3. Turn the ignition to LOCK/OFF. 4. For vehicles with key access,

remove the key and take it with you. If you can leave the vehicle with the ignition key in your hand, the vehicle is in P (Park). For vehicles with the keyless access system, take the keyless access transmitter with you.

Leaving the Vehicle With the Engine Running (Automatic Transmission)

{ 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 9‑22. If you are towing a trailer, see Driving Characteristics and Towing Tips on page 9‑53.

If you have to leave the vehicle with the engine running, the vehicle must be in P (Park) and the parking brake set. After shifting into P (Park), try to move the shift lever out without first pushing the button on the shift lever. If you can, the shift lever was not fully locked into P (Park). Torque Lock (Automatic Transmission) 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" listed previously. If torque lock does occur, the vehicle may need to be pushed uphill by another vehicle to relieve the parking pawl pressure, so you can shift out of P (Park).

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. R (Reverse): Use this gear to back up.

At low vehicle speeds, R (Reverse) can be used to rock the vehicle back and forth to get out of snow, ice, or sand without damaging your transmission. See If the Vehicle Is Stuck on page 9‑9 for additional information. In this position, the N (Neutral): engine does not connect with the wheels. To restart when the vehicle is already moving, use N (Neutral) only. You can also use N (Neutral) when the vehicle is being towed.

{ 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 55 km/h

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

. Going about 55 km/h (35 mph) or

more, push the accelerator all the way down. The transmission will shift down to a lower gear and have more power.

Downshifting the transmission in slippery road conditions could result in skidding; see “Skidding” under Loss of Control on page 9‑5

When the CTS-V is in D (Drive), the first forward gear automatic shift after start will be from 1 (First) gear. Following starts will begin in 2 (Second) gear. When in M (Manual Mode), the vehicle will start in 1 (First) gear every time. M (Manual Mode): This position allows the driver to select the range of gears appropriate for current driving conditions. See Driver Shift Control (DSC) later in this section. Notice: Spinning the tires or holding the vehicle in one place on a hill using only the accelerator pedal may damage the transmission. If you are stuck, do not spin the tires. When stopping on a hill, use the brakes to hold the vehicle in place.

Manual Mode

Driver Shift Control (DSC) or Tap Shift Notice: Driving with the engine at a high rpm without upshifting while using Driver Shift Control (DSC), could damage the vehicle. Always upshift when necessary while using DSC. Vehicles with DSC may either use the shift lever or the tap shift controls on back of the steering wheel to manually shift the automatic transmission. To use the DSC feature using the shift lever: 1. Move the shift lever to the right

from D (Drive) to M (Manual Mode).

The vehicle will be in sport mode and will shift automatically if the shift lever is not moved forward or rearward. The transmission may remain in a gear longer than it would in the normal driving mode based on braking, throttle input, and vehicle lateral acceleration. SPORT MODE will be displayed in the DIC momentarily.

2. To go from sport mode to DSC, move the shift lever forward to upshift or rearward to downshift.

3. To exit DSC and enter sport

mode, hold the shift lever in the upshift/forward position briefly.

2. Tap the left control to downshift,

and the right control to upshift.

3. To return to sport mode, hold the

right upshift control briefly, or hold the shift lever forward briefly, or return the shift lever to D (Drive).

With the shift lever in D (Drive), the tap shift controls will activate a temporary tap manual shift mode, allowing the transmission to be manually shifted. Automatic shifts return after no manual shifts have been done for seven to 10 second. The temporary tap mode can also be deactivated by holding the right upshift control briefly.

The tachometer display indicates which gear the vehicle is in. The number indicates the requested gear range when moving the shift lever forward or rearward. CTS-V vehicles use tracer lights around the outside of the tachometer as a performance upshift light. These tracers flash to indicate when to shift to the next higher gear to avoid the engine speed limit. See Tachometer on page 5‑13 for more information.

If equipped, the tap shift controls are on the back of the steering wheel. The tap shift controls can be used in D (Drive), M (Manual Mode) with Sport Mode automatic shift active, or M (Manual Mode) with Manual Shifting Mode. To use the DSC feature using the Tap Shift controls: 1. Move the shift lever to the

right from D (Drive) to M (Manual Mode).

While using the DSC feature, the vehicle will have firmer, quicker shifting. You can use this for sport driving or when climbing or descending hills, to stay in gear longer, or to downshift for more power or engine braking. The transmission will only allow you to shift into gears appropriate for the vehicle speed and engine revolutions per minute (RPM). The transmission will not automatically shift to the next lower gear if the engine rpm is too high, nor to the next higher gear when the maximum engine rpm is reached. If shifting is prevented for any reason, the currently selected gear will flash multiple times, indicating that the transmission has not shifted gears.

While in the DSC mode, the CTS automatic transmission will automatically downshift when the vehicle comes to a stop. This will allow for more power during acceleration. The CTS-V automatic transmission will not automatically downshift on hard acceleration when in DSC mode. When accelerating the vehicle from a stop in snowy and icy conditions, it is suggested to shift into second gear. A higher gear allows the vehicle to gain more traction on slippery surfaces.

Driving and Operating

Shift into 1 (First) when you are going less than 40 km/h (25 mph). For CTS-V, shift into 1 (First) when you are going less than 64 km/h (40 mph). After a complete stop, if it is hard to shift into 1 (First), let up on the clutch pedal, then press it back down and shift into 1 (First). 2 (Second): Press the clutch pedal and let up on the accelerator pedal, then shift into 2 (Second). Then, slowly let up on the clutch pedal while accelerating. 3 (Third), 4 (Fourth), 5 (Fifth), and 6 (Sixth): Shift into 3 (Third), 4 (Fourth), 5 (Fifth), and 6 (Sixth) the same for 2 (Second). To stop, let up on the accelerator pedal and press the brake pedal. Just before the vehicle stops, press the clutch pedal and the brake pedal, and shift to Neutral. Neutral: Use this position when you start or idle your engine. Your shift lever is in Neutral when it is centered in the shift pattern, not in any gear.

R (Reverse): To back up, press down the clutch pedal, completely stop the vehicle, and shift into R (Reverse). Let up on the clutch pedal slowly while pressing the accelerator pedal. The CTS-V transmission prevents easily shifting into R (Reverse) using normal shifting force while the vehicle is moving at more than 5 km/h (3 mph), or when the ignition is in LOCK/OFF. Shift Speeds (Manual Transmission)

{ WARNING

If you skip a gear when you downshift, you could lose control of the vehicle. You could injure yourself or others. Do not shift down more than one gear at a time when you downshift.

Notice: If you skip more than one gear when you downshift, or if you race the engine when you

release the clutch pedal while downshifting, you could damage the engine, clutch, driveshaft or the transmission. Do not skip gears or race the engine when downshifting. If the vehicle speed drops below 32 km/h (20 mph), or if the engine is not running smoothly, downshift to the next lower gear. You may have to downshift two or more gears to keep the engine running smoothly or for good performance.

Up-Shift Light

Vehicles with a manual transmission have an up-shift light on the instrument panel. This light shows when to shift to the next higher gear for the best fuel economy.

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Black plate (31,1)

Skip Shift (CTS-V) Under light acceleration, the transmission will only allow you to shift from 1 (First) to 4 (Fourth). Shifts from 1 (First) to 2 (Second) or 3 (Third) are not allowed. This helps improve fuel mileage. Under harder acceleration, Skip Shift is disabled, and the driver has all gears available.

When this light comes on, you can shift to the next higher gear if weather, road, and traffic conditions allow. For the best fuel economy, accelerate slowly and shift when the light comes on. While you accelerate, it is normal for the light to go on and off if you quickly change the position of the accelerator. Ignore the light when you downshift. CTS-V vehicles use tracer lights around the outside of the tachometer as a performance up-shift light. These tracers flash to indicate when to shift to the next higher gear to avoid the engine speed limit. See Tachometer on page 5‑13 for more information.

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 5‑23.

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.

Vehicles with the electric parking brake (EPB) have a switch in the center console. The EPB takes the place of the manual parking brake system, the foot pedal, and release handle. The EPB can always be activated, even if the ignition is off. To avoid

draining the battery, do not operate the EPB too often without the engine running. The system has two warning lights and five Driver Information Center (DIC) messages. See Brake System Warning Light on page 5‑21 and Driver Information Center (DIC) on page 5‑27 for more information. In case of insufficient electrical power, the EPB cannot be applied or released. EPB Apply The EPB can be applied any time the vehicle is stopped. The EPB is applied by momentarily lifting up on the EPB switch. Once fully applied, the BRAKE light will be on, and the DIC message PARK BRAKE SET will be displayed. While the brake is being applied, the status light will flash until full apply is reached. If the light does not come on, or remains flashing, you need to have the vehicle serviced. Do not drive the vehicle if the BRAKE light

is flashing. See your dealer. See Brake System Warning Light on page 5‑21 for more information. If the EPB is applied while the vehicle is in motion, a chime will sound, and the DIC message RELEASE PARK BRAKE SWITCH will be displayed. The vehicle will decelerate as long as the switch is held in the up position. Releasing the EPB switch during the deceleration will release the parking brake. If the switch is held in the up position until the vehicle comes to a stop, the EPB will remain applied. If the BRAKE light is on, either the EPB is applied, or there is a failure in the hydraulic brake system. If this light is flashing continuously, the EPB is only partially applied or released, or there is a problem with the EPB. The DIC message SERVICE PARK BRAKE will be displayed. If this light is flashing continuously, release the EPB, and

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

attempt to apply it again. If this light continues to flash, do not drive the vehicle. See your dealer. If the yellow light is on, the EPB has detected an error in another system and is operating with reduced functionality. To apply the EPB when this light is on, lift up on the EPB switch and hold it in the up position. Full application of the parking brake by the EPB system may take a longer period of time than normal when this light is on. Continue to hold the switch until the BRAKE light remains on. If the yellow light is on, see your dealer. If the EPB fails to apply, the rear wheels should be blocked to prevent vehicle movement. EPB Release To release the EPB, turn the ignition switch to the ACC/ACCESSORY or ON/RUN position, apply and hold the brake pedal, and push down momentarily on the EPB switch. If you attempt to release the EPB without the brake pedal applied, a

chime will sound, and the DIC message STEP ON BRAKE TO RELEASE PARK BRAKE will be displayed. The EPB is released when the BRAKE light is off and the DIC message PARK BRAKE RELEASED is displayed. If the yellow light is on, the EPB has detected an error in another system and is operating with reduced functionality. To release the EPB when this light is on, push down on the EPB switch and hold it in the down position. EPB release may take a longer period of time than normal when this light is on. Continue to hold the switch until the BRAKE light is off. If the yellow light is on, see your dealer. 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 red brake warning light is off before driving.

Automatic EPB Release The EPB will automatically release if the vehicle is running, placed into gear, and an attempt is made to drive away. Avoid rapid acceleration when the EPB is applied, to preserve park brake lining life. The EPB can also be used to prevent roll back for vehicles with a manual transmission taking off on a hill. In a situation where no roll back is desired, an applied EPB will allow both feet to be used for the clutch and accelerator pedals in preparation for starting the vehicle moving in the intended direction. In this situation, perform the normal clutch and/or accelerator actions required to begin moving the vehicle. There is no need to push the switch to release the EPB. If you are towing a trailer and parking on a hill, see Driving Characteristics and Towing Tips on page 9‑53 for more information.

Driving and Operating

Brake Assist (Except CTS-V) This vehicle has a brake assist feature designed to assist the driver in stopping or decreasing vehicle speed in emergency driving conditions. This feature uses the stability system hydraulic brake control module to supplement the power brake system under conditions where the driver has quickly and forcefully applied the brake pedal in an attempt to quickly stop or slow down the vehicle. The stability system hydraulic brake control module increases brake pressure at each corner of the vehicle until the ABS activates. Minor brake pedal pulsation or pedal movement during this time is normal and the driver should continue to apply the brake pedal as the driving situation dictates. The brake assist feature will automatically disengage when the brake pedal is released or brake pedal pressure is quickly decreased.

Ride Control Systems

Traction Control System (TCS) The vehicle has a Traction Control System (TCS) that limits wheel spin. This is especially useful in slippery road conditions. On a rear-wheel-drive vehicle, the system operates if it senses that one or both of the rear wheels are spinning or beginning to lose traction. On an All-Wheel-Drive (AWD) vehicle, the system will operate if it senses that any of the wheels are spinning or beginning to lose traction. When this happens, the system brakes the spinning wheel(s) and/or reduces engine power to limit wheel spin. The system may be heard or felt while it is working, but this is normal.

The TCS/StabiliTrak light flashes when the traction control system is limiting wheel spin. The TCS/StabiliTrak light comes on and the SERVICE TRACTION CONTROL message will be displayed in the DIC if there is a problem with the traction control system. When the TCS/StabiliTrak light is on, the system will not limit wheel spin. Adjust your driving accordingly. See Traction Control System (TCS)/StabiliTrak® Light on page 5‑24. TCS automatically comes on whenever the vehicle is started. To limit wheel spin, especially in slippery road conditions, the system should always be left on, but it may be necessary to turn the system off if the vehicle is stuck in sand, mud

or snow and rocking the vehicle is required. See If the Vehicle Is Stuck on page 9‑9. See Winter Driving on page 9‑8 for information on using TCS when driving in snowy or icy conditions.

The TCS/StabiliTrak button is on the instrument panel (CTS) or the steering wheel (CTS-V). Press and release the TCS/ StabiliTrak button and the traction control system will turn off and TRACTION CONTROL OFF will be displayed in the DIC. Press the button again to turn the system back on. For information on turning StabiliTrak off and on, see StabiliTrak System following.

Adding non-dealer accessories can affect your vehicle's performance. See Accessories and Modifications on page 10‑3.

StabiliTrak® System The vehicle has an electronic stability control system called StabiliTrak. It is an advanced computer controlled system that assists with directional control of the vehicle in difficult driving conditions. StabiliTrak activates when the system senses a discrepancy between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the direction which you are steering.

When the system activates, this warning light flashes on the instrument panel. A noise may be heard or a vibration may be felt in the brake pedal. This is normal. Continue to steer the vehicle in the intended direction. If there is a problem detected with StabiliTrak, SERVICE STABILITRAK displays on the Driver Information Center (DIC) and the TCS/StabiliTrak light comes on the instrument cluster. When this message and light displays, the system is not operational. Driving should be adjusted accordingly. See Ride Control System Messages on page 5‑40 and Traction Control System (TCS)/StabiliTrak® Light on page 5‑24.

The TCS/StabiliTrak button is on the instrument panel (CTS) or the steering wheel (CTS-V). StabiliTrak comes on automatically whenever the vehicle is started. The system should be left on to help assist with directional control of the vehicle.

If StabiliTrak needs to be turned off, press and hold the TCS/StabiliTrak button until the StabiliTrak Off light comes on and the appropriate DIC

message displays. Press the TCS/ StabiliTrak button again to turn both systems back on. If cruise control is being used when the StabiliTrak activates, the cruise control will automatically disengage. When road conditions allow, reengage the cruise control. See Cruise Control on page 9‑39.

Competitive Driving Mode To select this optional handling mode, press the TCS/ StabiliTrak button quickly two times and STABILITRAK COMPETITIVE MODE displays in the Driver Information Center (DIC). While in the StabiliTrak Competitive Mode, the StabiliTrak Off light comes on, TCS does not limit wheel spin, and more effort is required to turn the steering wheel. Adjust your driving accordingly. Press the TCS/StabiliTrak button again, or turn the ignition to ACC/ ACCESSORY and restart the

vehicle, to turn TCS back on and turn the TCS/StabiliTrak warning light off. Notice: When traction control is turned off, or Competitive Driving Mode is active, it is possible to lose traction. If you attempt to shift with the drive wheels spinning with a loss of traction, it is possible to cause damage to the transmission. Do not attempt to shift when the drive wheels do not have traction. Damage caused by misuse of the vehicle is not covered. See the warranty book for additional information.

Magnetic Ride Control With this feature on the CTS-V, the Magnetic Ride Control system adjusts the ride of the vehicle to Tour or Sport modes. Magnetic Ride Control monitors the suspension system to determine the proper system response.

Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Black plate (39,1)

TOUR: Use for normal city and highway driving. This setting provides a smooth, soft ride. SPORT: Use where road conditions or personal preference demand more control. This setting provides more “feel,” or response to road conditions. The setting can be changed at any time. Based on road conditions, steering wheel angle, and the vehicle speed, the system automatically adjusts to provide the best handling while providing a smooth ride. The Tour and Sport modes will feel similar on a smooth road. Select a new setting whenever driving conditions change. The Driver Information Center (DIC) briefly displays SUSPENSION MODE TOUR or SUSPENSION MODE SPORT on vehicle startup or when a new mode is selected.

Press and release this button in the center of the instrument panel, to change modes.

Limited-Slip Rear Axle Vehicles with a limited-slip rear axle can give more traction on snow, mud, ice, sand, or gravel. When traction is low, this feature allows the drive wheel with the most traction to move the vehicle. The limited-slip rear axle also gives the driver enhanced control when cornering hard or completing a maneuver, such as a lane change.

Cruise Control

{ 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.

With cruise control, a speed of about 40 km/h (25 mph) or more can be maintained without keeping your foot on the accelerator. Cruise control does not work at speeds below about 40 km/h (25 mph). When the brakes are applied, the cruise control turns off.
