Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 mi) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty. Always use DEX-COOL (silicate-free) coolant in the vehicle.
Engine Coolant The cooling system in the vehicle for all engines and the intercooler is filled with DEX-COOL®. This coolant is designed to remain in the vehicle for 5 years or 240 000 km (150,000 mi), whichever occurs first. The following explains the cooling system and how to check and add coolant when it is low. If there is a problem with engine overheating, see Engine Overheating on page 10‑22.
What to Use
{ WARNING
Adding only plain water or some other liquid to the cooling system can be dangerous. Plain water and other liquids, can boil before the proper coolant mixture will. The coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, the engine could get too hot but you would not get the overheat warning. The engine could catch fire and you or others could be burned. Use a 50/ 50 mixture of clean, drinkable water and DEX-COOL coolant.
Use a 50/50 mixture of clean, drinkable water and DEX-COOL coolant. If using this mixture, nothing else needs to be added. This mixture: . Gives freezing protection down
to −37°C (−34°F), outside temperature.
. Gives boiling protection up to
129°C (265°F), engine temperature.
. Protects against rust and
corrosion.
. Will not damage aluminum parts. . Helps keep the proper engine
temperature.
Notice: If improper coolant mixture, inhibitors, or additives are used in the vehicle cooling system, the engine could overheat and be damaged. Too much water in the mixture can freeze and crack engine cooling parts. The repairs would not be covered by the warranty. Use only the proper mixture of engine
Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

coolant for the cooling system. See Recommended Fluids and Lubricants on page 11‑13. Never dispose of engine coolant by putting it in the trash, pouring it on the ground, or into sewers, streams, or bodies of water. Have the coolant changed by an authorized service center, familiar with legal requirements regarding used coolant disposal. This will help protect the environment and your health. Checking Coolant The vehicle must be on a level surface when checking the coolant level. The engine coolant reservoir is in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview on page 10‑6. Check to see if coolant is visible in the surge tank. If the coolant inside the surge tank is boiling, do not do anything else until it cools down.
If coolant is visible but the coolant level is not at or above the FULL COLD mark, add a 50/50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant surge tank, but be sure the cooling system is cool before this is done. If the engine is warm or hot, the coolant level should be at or above the FROID/FULL COLD line on the side of the coolant surge tank. If the engine is cold, the coolant level should be near the FROID/FULL COLD line on the side of the coolant surge tank. If it is not, there could be a leak in the cooling system. How to Add Coolant to the Surge Tank
{ WARNING
You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol

and it will burn if the engine parts are hot enough. Do not spill coolant on a hot engine.
Notice: This vehicle has a specific coolant fill procedure. Failure to follow this procedure could cause the engine to overheat and be severely damaged.
{ WARNING
Steam and scalding liquids from a hot cooling system can blow out and burn you badly. Never turn the cap when the cooling system, including the surge tank pressure cap, is hot. Wait for the cooling system and surge tank pressure cap to cool.

If coolant is needed, add the proper DEX-COOL coolant mixture at the coolant surge tank. If no coolant is visible in the surge tank, add coolant as follows: 1. Remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly counterclockwise about one-quarter turn and then stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left.
2. Keep turning the pressure cap
slowly and remove it.
3. Fill the coolant surge tank with
the proper mixture, to slightly above the FROID/FULL COLD line on the side of the coolant surge tank.
4. With the coolant surge tank
pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. The upper radiator hose is the top hose coming out of the radiator, on the passenger side of the vehicle. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mixture to the coolant surge tank until the level reaches the FROID/FULL COLD line on the side of the coolant surge tank. 5. Replace the pressure cap. Be
sure the pressure cap is hand-tight and fully seated.
Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12

Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. Recheck the coolant level in the bottle next time you use your vehicle to ensure the system is full when cold. Checking Coolant in the Intercooler System (CTS-V) The vehicle must be on a level surface when checking the coolant level. The super charged engine intercooler coolant fill neck is in the engine compartment on the passenger side of the vehicle. See Engine Compartment Overview on page 10‑6. On the coolant fill neck, there is a cold fill region between the two horizontal lines shown. Check to see if coolant is visible in the coolant fill neck. If the coolant is not visible or below the cold fill
region in the fill neck, add a 50/ 50 mixture of clean, drinkable water and DEX-COOL coolant at the coolant fill bottle, but be sure the cooling system is cool before this is done. Adding Coolant to the Intercooler System Coolant (CTS-V)

about one-quarter of a turn. If you hear a hiss, wait for that to stop. This allows any pressure still left to be vented.
2. Keep turning the pressure cap
slowly and remove it.
3. Add the proper DEX-COOL
coolant mixture to the fill neck until the coolant is within the cold fill region. With the intercooler system pressure cap off, start the engine and let it run for a couple of minutes. Then turn the engine off. By this time, the coolant level inside the fill neck may be lower. If the level drops where coolant is no longer within the cold fill region of the fill neck with the engine off, add more of the DEX-COOL coolant mixture to the fill neck until the level is again visible in the cold fill region.
4. Replace the pressure cap tightly.

Notice: If the pressure cap is not tightly installed, coolant loss and possible engine damage may occur. Be sure the cap is properly and tightly secured. If the coolant is not at the proper level when the system cools down again, see your dealer.
Engine Overheating The vehicle has several indicators to warn of engine overheating. There are two engine hot messages that may be displayed in the Driver Information Center (DIC). See Engine Cooling System Messages on page 5‑34 for more information. You may decide not to lift the hood when one of these warnings appear, but get service help right away. See Roadside Service (U.S. and Canada) on page 13‑7 or Roadside Service (Mexico) on page 13‑9. If you do decide to lift the hood, make sure the vehicle is parked on a level surface.
Then check to see if the engine cooling fans are running. If the engine is overheating, the fan(s) should be running. If they are not, do not continue to run the engine and have the vehicle serviced. Notice: Running the engine without coolant may cause damage or a fire. Vehicle damage would not be covered by the warranty. See Overheated Engine Protection Operating Mode on page 10‑23 for information on driving to a safe place in an emergency. If Steam Is Coming from the Engine Compartment { WARNING
Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it

temperature and to the highest fan speed. Open the windows as necessary. In heavy traffic, let the engine idle in N (Neutral) while stopped. If it is safe to do so, pull off the road, shift to P (Park) or N (Neutral) and let the engine idle.
If the temperature overheat gauge is no longer in the overheat zone or an overheat warning no longer displays, the vehicle can be driven. Continue to drive the vehicle slow for about 10 minutes. Keep a safe vehicle distance from the car in front of you. If the warning does not come back on, continue to drive normally.
If the warning continues, pull over, stop, and park the vehicle right away. If there is no sign of steam, idle the engine for three minutes while parked. If the warning is still displayed, turn off the engine until it cools down. Also, see “Overheated Engine Protection Operating Mode†next in this section.
Overheated Engine Protection Operating Mode This operating mode allows the vehicle to be driven to a safe place in an emergency. Should a hot engine condition exist, an overheat protection mode which alternates firing groups of cylinders helps prevent engine damage. In this mode, there is a loss in power and engine performance. Driving extended distances and/or towing a trailer in the overheat protection mode should be avoided.

reservoir clean.
3. Unscrew the cap and wipe the
dipstick with a clean rag.
4. Replace the cap and completely
tighten it.
5. Remove the cap again and look at the fluid level on the dipstick.
The level should be between the HOT and COLD marks. If necessary, add only enough fluid to bring the level between the marks. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 11‑13. Always use the proper fluid.
Washer Fluid
What to Use When adding windshield washer fluid to the vehicle, be sure to read the manufacturer's instructions before use. If you will be operating
your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Adding Washer Fluid The WASHER FLUID LOW ADD FLUID message will appear on the Driver Information Center (DIC) when the fluid level is low. See Washer Fluid Messages on page 5‑45.
Open the cap with the washer symbol on it. Add washer fluid until the tank is full. See Engine Compartment Overview on page 10‑6 for reservoir location.
Notice
. When using concentrated
washer fluid, follow the manufacturer instructions for adding water.
. Do not mix water with
ready-to-use washer fluid. Water can cause the solution to freeze and damage the washer fluid tank and other parts of the washer system.
. Fill the washer fluid tank only
three-quarters full when it is very cold. This allows for fluid expansion if freezing occurs, which could damage the tank if it is completely full.
. Do not use engine coolant
(antifreeze) in the windshield washer. It can damage the windshield washer system and paint.

Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. The vehicle was designed and tested with top-quality brake parts. When parts of the braking system are replaced, be sure to get new, approved replacement parts. If this is not done, the brakes might not work properly. For example, installing disc brake pads that are wrong for the vehicle, can change the balance between the front and rear brakes — for the worse. The braking performance expected can change in many other ways if the wrong replacement brake parts are installed.
Brakes This vehicle has disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound can come and go or be heard all the time the vehicle is moving, except when applying the brake pedal firmly.
{ WARNING
The brake wear warning sound means that soon the brakes will not work well. That could lead to a crash. When the brake wear warning sound is heard, have the vehicle serviced.
Notice: Continuing to drive with worn-out brake pads could result in costly brake repair.
Some driving conditions or climates can cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with the brakes. Properly torqued wheel nuts are necessary to help prevent brake pulsation. When tires are rotated, inspect brake pads for wear and evenly tighten wheel nuts in the proper sequence to torque specifications in Capacities and Specifications on page 12‑2. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign that brake service might be required. Brake Adjustment Every time the brakes are applied, with or without the vehicle moving, the brakes adjust for wear.

Brake Fluid
The brake master cylinder reservoir is filled with DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 10‑6 for the location of the reservoir. There are only two reasons why the brake fluid level in the reservoir might go down:
The brake fluid level goes down because of normal brake lining wear. When new linings are installed, the fluid level goes back up.
. A fluid leak in the brake
hydraulic system can also cause a low fluid level. Have the brake
hydraulic system fixed, since a leak means that sooner or later the brakes will not work well.
Do not top off the brake fluid. Adding fluid does not correct a leak. If fluid is added when the linings are worn, there will be too much fluid when new brake linings are installed. Add or remove brake fluid, as necessary, only when work is done on the brake hydraulic system.
{ WARNING
If too much brake fluid is added, it can spill on the engine and burn, if the engine is hot enough. You or others could be burned, and the vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system.
When the brake fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 5‑21.
What to Add Use only new DOT 3 brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11‑13. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This helps keep dirt from entering the reservoir.
{ WARNING
With the wrong kind of fluid in the brake hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake fluid.
Notice
. Using the wrong fluid can
badly damage brake hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake
Cadillac CTS/CTS-V Owner Manual - 2013 - CRC - 4/18/12
Black plate (27,1)
hydraulic system can damage brake hydraulic system parts so badly that they will have to be replaced. Do not let someone put in the wrong kind of fluid.
. If brake fluid is spilled on the
vehicle's painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on the vehicle. If you do, wash it off immediately.
Battery The battery is in the trunk, behind the trim panel, on the passenger side of the vehicle. Refer to the replacement number shown on the original battery label when a new battery is needed.
{ WARNING
Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.
After a power loss, such as disconnecting the battery or removing the maxi fuses in the power distribution fuse block, the following steps must be performed to calibrate the electronic throttle control. If this is not done, the engine will not run properly. 1. Turn the ignition on but do not
start the engine.
2. Leave the ignition on for at least
three minutes so that the electronic throttle control will cycle and relearn its home position.
3. Turn the ignition off.

Headlamp Wiring An electrical overload may cause the lamps to go on and off, or in some cases to remain off. Have the headlamp wiring checked right away if the lamps go on and off or remain off. Windshield Wipers If the wiper motor overheats due to heavy snow or ice, the windshield wipers will stop until the motor cools and will then restart. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. If the overload is caused by an electrical problem and not snow or ice, be sure to get it fixed.
Electrical System
Electrical System Overload The vehicle has fuses and circuit breakers to protect against an electrical system overload. When the current electrical load is too heavy, the circuit breaker opens and closes, protecting the circuit until the current load returns to normal or the problem is fixed. This greatly reduces the chance of circuit overload and fire caused by electrical problems. Fuses and circuit breakers protect power devices in the vehicle. Replace a bad fuse with a new one of the identical size and rating. If there is a problem on the road and a fuse needs to be replaced, the same amperage fuse can be borrowed. Choose some feature of the vehicle that is not needed to use and replace it as soon as possible.

Fuses and Circuit Breakers The wiring circuits in the vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of damage caused by electrical problems. To check a fuse, look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure to replace a bad fuse with a new one of the identical size and rating. Fuses of the same amperage can be temporarily borrowed from another fuse location, if a fuse goes out. Replace the fuse as soon as you can.
To identify and check fuses, circuit
breakers, and relays, see Engine
