Engine Oil To ensure proper engine performance and long life, careful attention must be paid to engine oil. Following these simple, but important steps will help protect your investment: . Always use engine oil approved to the proper specification and of the proper viscosity grade. See “Selecting the Right Engine Oil” in this section.
. Check the engine oil level regularly and maintain the proper oil level. See “Checking Engine Oil” and “When to Add Engine Oil” in this section.
. Change the engine oil at the
appropriate time. See Engine Oil Life System on page 10‑13. . Always dispose of engine oil
properly. See “What to Do with Used Oil” in this section.
Vehicle Care
10-11
Checking Engine Oil It is a good idea to check the engine oil level at each fuel fill. In order to get an accurate reading, the vehicle must be on level ground. The engine oil dipstick handle is a loop. See Engine Compartment Overview on page 10‑6 for the location of the engine oil dipstick. 1.
If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.
{ WARNING
The engine oil dipstick handle may be hot; it could burn you. Use a towel or glove to touch the dipstick handle.

2. Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level.
When to Add Engine Oil If the oil is below the cross-hatched area at the tip of the dipstick, add 1 L (1 qt) of the recommended oil and then recheck the level. See “Selecting the Right Engine Oil” in this section for an explanation of what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 12‑2. Notice: Do not add too much oil. Oil levels above or below the acceptable operating range shown on the dipstick are harmful to the engine. If you find that you have an oil level above the operating range, i.e., the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could
be damaged. You should drain out the excess oil or limit driving of the vehicle and seek a service professional to remove the excess amount of oil. See Engine Compartment Overview on page 10‑6 for the location of the engine oil fill cap. Add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back in when through. Selecting the Right Engine Oil Selecting the right engine oil depends on both the proper oil specification and viscosity grade. See Recommended Fluids and Lubricants on page 11‑13.
Specification Use and ask for licensed engine oils with the dexos1® approved certification mark. Engine oils meeting the requirements for the vehicle should have the dexos1
approved certification mark.This certification mark indicates that the oil has been approved to the dexos1 specification.
Notice: Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. Check with your dealer or service provider on whether the oil is approved to the dexos1 specification.
Viscosity Grade SAE 5W-30 is the best viscosity grade for the 2.0L L4 engine and the 3.6L V6 engine. SAE 5W-20 is the best viscosity grade for the 2.5L L4 engine. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50.

Engine Oil Life System
When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on a combination of factors which include engine revolutions, engine temperature, and miles driven. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed.
Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29°C (−20°F), an SAE 0W-30 oil may be used. An oil of this viscosity grade will provide easier cold starting for the engine at extremely low temperatures. When selecting an oil of the appropriate viscosity grade, always select an oil of the correct specification. See “Specification” earlier in this section for more information. Engine Oil Additives/Engine Oil Flushes Do not add anything to the oil. The recommended oils with the dexos specification and displaying the dexos certification mark are all that is needed for good performance and engine protection. Engine oil system flushes are not recommended and could cause engine damage not covered by the vehicle warranty.
What to Do with Used Oil Used engine oil contains certain elements that can be unhealthy for your skin and could even cause cancer. Do not let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly dispose of clothing or rags containing used engine oil. See the manufacturer's warnings about the use and disposal of oil products. Used oil can be a threat to the environment. If you change your own oil, be sure to drain all the oil from the filter before disposal. Never dispose of oil by putting it in the trash or pouring it on the ground, into sewers, or into streams or bodies of water. Recycle it by taking it to a place that collects used oil.

Vehicle Care
When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. See Engine Oil Messages on page 5‑35. Change the oil as soon as possible within the next 1 000 km (600 mi). It is possible that, if driving under the best conditions, the oil life system might indicate that an oil change is not necessary for up to a year. The engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer has trained service people who will perform this work and reset the system. It is also important to check the oil regularly over the course of an oil drain interval and keep it at the proper level.
If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 mi) since the last oil change. Remember to reset the oil life system whenever the oil is changed. How to Reset the Engine Oil Life System Reset the system whenever the engine oil is changed so that the system can calculate the next engine oil change. To reset the system: 1. Using the DIC controls on the
right side of the steering wheel, display REMAINING OIL LIFE on the DIC. See Driver Information Center (DIC) on page 5‑26. When remaining oil life is low, the CHANGE ENGINE OIL SOON message will appear on the display. See Engine Oil Messages on page 5‑35.
2. Press SEL on the DIC controls
and hold SEL down for a few seconds to clear the CHANGE ENGINE OIL SOON message and reset the oil life at 100%. Be careful not to reset the oil life display accidentally at any time other than after the oil is changed. It cannot be reset accurately until the next oil change.
The oil life system can also be reset as follows: 1. Turn the ignition on with the
engine off.
2. Fully press and release the
accelerator pedal three times within five seconds. If the CHANGE ENGINE OIL SOON message is not on, the system is reset.
The system is reset when the CHANGE ENGINE OIL SOON message is off.
Cadillac ATS Owner Manual - 2013 - CRC - 10/5/12
Black plate (15,1)
If the CHANGE ENGINE OIL SOON message comes back on when the vehicle is started, the engine oil life system has not been reset. Repeat the procedure.
Automatic Transmission Fluid
How to Check Automatic Transmission Fluid It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible. The vehicle is not equipped with a transmission fluid level dipstick. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, this should be done at the dealer. Contact the dealer for additional information.
Change the fluid and filter at the intervals listed in Maintenance Schedule on page 11‑3, and be sure to use the fluid listed in Recommended Fluids and Lubricants on page 11‑13.
Manual Transmission Fluid
How to Check Manual Transmission Fluid It is not necessary to check the manual transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 11‑13
for the proper fluid to use.Hydraulic Clutch For vehicles with a manual transmission, it is not necessary to regularly check brake/clutch fluid unless there is a leak suspected.
Vehicle Care
10-15
Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. When to Check and What to Use
The brake/hydraulic clutch fluid reservoir cap has either a symbol or text specifying the type of brake fluid. The common brake/clutch fluid reservoir is filled with GM approved DOT 3 brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 10‑6 for reservoir location.

Vehicle Care
How to Check and Add Fluid Visually check the brake/clutch fluid reservoir to make sure the fluid level is at the MIN (minimum) line on the side of the reservoir. The brake/ hydraulic clutch fluid system should be closed and sealed. Do not remove the cap to check the fluid level or to top off the fluid level. Remove the cap only when necessary to add the proper fluid until the level reaches the MIN line.
Engine Air Cleaner/Filter The engine air cleaner/filter is in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview on page 10‑6 for location.
When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the scheduled maintenance intervals. See Maintenance Schedule on page 11‑3. If you are driving in dusty/dirty conditions, inspect the filter at each engine oil change. How to Inspect the Engine Air Cleaner/Filter To inspect the engine air cleaner/ filter, remove the filter from the vehicle and lightly shake the filter to release loose dust and dirt. If the filter remains covered with dirt, a new filter is required.

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.
Vehicle Care
10-19
Checking Coolant The vehicle must be on a level surface when checking the coolant level. It is normal to see coolant moving in the upper coolant hose return line when the engine is running. It is also normal to see bubbles entering the surge tank through the small hose. Check to see if coolant is visible in the coolant surge tank. If the coolant inside the coolant 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 COLD FILL line, add a 50/50 mixture of clean drinkable water and DEX-COOL coolant. Be sure the cooling system is cool before this is done.

2. Keep turning the pressure cap slowly and remove it. Open the surge tank service port cap to the lower chamber
proper DEX-COOL coolant mixture to the surge tank top chamber until the level reaches the bottom of the fill neck.
3. Fill the surge tank top chamber
5. Replace the surge tank pressure
with the proper DEX-COOL coolant mixture to the bottom of the fill neck. The top chamber needs to be completely full. Fill the surge tank bottom chamber through the service port to approximately half.
4. With the coolant surge tank
pressure cap off and the surge tank service port cap open, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fan. By this time, the coolant level inside the coolant surge tank top chamber may be lower. If the level is lower, add more of the
cap tightly and close the surge tank service port cap.
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. Check the level in the surge tank top and bottom chambers when the cooling system has cooled down. If the coolant is not at the proper levels, repeat Steps 1–3 and reinstall the pressure cap and close the service port. If the coolant still is not at the proper levels when the system cools down again, see your dealer.
1. Remove the coolant surge tank
pressure cap from the top chamber 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. If you hear a hiss, wait for that to stop. This will allow any pressure still left to be vented out the discharge hose.

Engine Overheating The vehicle has an indicator to warn of the engine overheating. If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Service (Mexico) on page 13‑7 or Roadside Service (U.S. and Canada) on page 13‑10. If the decision is made to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, do not continue to run the engine. 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.
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 off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when the engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine is cool.
If No Steam Is Coming from the Engine Compartment If an engine overheat warning is displayed but no steam can be seen or heard, the problem may not be too serious. Sometimes the engine can get a little too hot when the vehicle: . Climbs a long hill on a hot day. . Stops after high-speed driving. Idles for long periods in traffic.

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.
Washer Fluid
Notice
Vehicle Care
10-23
What to Use When windshield washer fluid is needed, be sure to read the manufacturer's instructions before use. If operating the vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. Adding Washer Fluid
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.
. 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.

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. 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.

fixed, since a leak means that sooner or later the brakes will not work well.
Do not top off the brake/clutch 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 fluid, as necessary, only when work is done on the brake/clutch 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/clutch hydraulic system.
Vehicle Care
10-25
Checking Brake Fluid The brake/clutch fluid can be checked without taking off the cap by looking at the brake/clutch fluid reservoir. The fluid level should be above MIN. If it is not, have the brake/ clutch hydraulic system checked to see if there is a leak. After work is done on the brake/ clutch hydraulic system, make sure the level is above MIN but not over the MAX mark. When the brake/clutch fluid falls to a low level, the brake warning light comes on. See Brake System Warning Light on page 5‑18.
What to Add Use only new GM approved DOT 3
brake fluid from a sealed container. See Recommended Fluids and Lubricants on page 11‑13.Brake Fluid
The brake/clutch 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/clutch
hydraulic system can also cause a low fluid level. Have the brake/clutch hydraulic system

Vehicle Care
Always clean the brake/clutch 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/clutch hydraulic system, the brakes might not work well. This could cause a crash. Always use the proper brake/clutch fluid.
Notice
. Using the wrong fluid can
badly damage brake/clutch hydraulic system parts. For example, just a few drops of mineral-based oil, such as engine oil, in the brake 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, beneath the trim panel, on the driver 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. 4. Start and run the engine for at
least 30 seconds.

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.

Vehicle Care
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 possible. To identify and check fuses, circuit breakers, and relays, see Engine Compartment Fuse Block on page 10‑34, Instrument Panel Fuse Block on page 10‑37, and Rear Compartment Fuse Block on page 10‑40.
Engine Compartment Fuse Block The underhood fuse block is on the passenger side of the engine compartment.
The vehicle may not be equipped with all of the fuses and relays shown. Notice: Spilling liquid on any electrical component on the vehicle may damage it. Always keep the covers on any electrical component.
Lift the fuse block cover to access the fuses.
