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.

Brake Assist 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.

Driving and Operating

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.

Hill Start Assist (HSA) Some vehicles have a Hill Start Assist (HSA) feature, which may be useful when the vehicle is stopped on a grade. This feature is designed to prevent the vehicle from rolling, either forward or rearward, during vehicle drive off. After the driver completely stops and holds the vehicle in a complete standstill on a grade, HSA will be automatically activated. During the transition period between when the driver releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds the braking pressure to ensure that there is no rolling. The brakes will automatically release when the accelerator pedal is applied within the two‐second window. It will not activate if the vehicle is in a drive gear and facing downhill or if the vehicle is facing uphill and in R (Reverse).

Ride Control Systems

Traction Control System (TCS) The vehicle may have a Traction Control System (TCS) that limits wheel slip. The system operates if it senses that one or both of the front wheels are slipping or beginning to lose traction. When this happens, the system reduces engine power and/or applies brake pressure to the slipping wheel(s). The system may be heard or felt while it is working, but this is normal. TCS automatically comes on whenever the vehicle is started. To limit wheel slip, especially in slippery road conditions, the system should always be left on. But, TCS can be turned off if needed.

Press and release the TCS/StabiliTrak button again to turn the system back on. It may be necessary to turn the system off if the vehicle gets stuck in sand, mud, or snow and rocking the vehicle is required. See If the Vehicle Is Stuck on page 9‑11 for more information. See also Winter Driving on page 9‑9 for information on using TCS when driving in snowy or icy conditions. Adding non‐GM accessories can affect the vehicle performance. See Accessories and Modifications on page 10‑3 for more information.

StabiliTrak® System The vehicle may have a vehicle stability enhancement 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 computer senses a difference between the intended path and the direction the vehicle is actually traveling. StabiliTrak selectively applies braking pressure to the vehicle brakes to help steer the vehicle in the intended direction. StabiliTrak comes on automatically whenever the vehicle is started. To assist with directional control of the vehicle, the system should always be left on. When StabiliTrak activates, d flashes on the instrument panel. A noise may be heard or vibration may be felt in the brake pedal. This is normal. Continue to steer the vehicle in the intended direction. See Traction Control System (TCS)/ StabiliTrak® Light on page 5‑18 for more information.

If a problem is detected with StabiliTrak, SERVICE STABILITRAK is displayed on the Driver Information Center (DIC). See Ride Control System Messages on page 5‑29. When this message is displayed and d comes on and stays on, the vehicle is safe to drive but the system is not operational. Driving should be adjusted accordingly. If d comes on and stays on, reset the system. To reset: 1. Stop the vehicle. 2. Turn the engine off and waiting

Drive Mode Control Drive Mode Control (DMC) analyzes the driving style and the active state of the vehicle and automatically changes the settings within the selected driving mode. When there is a more noticeable change in driving style or conditions, the driving mode is changed to Sport until the previous driving style returns. If Standard mode is selected and sport driving is detected, several settings of the Standard mode change to sport settings. If sport driving increases, DMC changes to Sport mode. If Tour mode is selected and sudden braking or cornering is necessary, DMC changes the suspension settings to Sport mode to increase vehicle stability. When the driving characteristic or the active state of the vehicle returns to the previous style, DMC changes the settings to the preselected driving mode.

Cruise Control With cruise control, the vehicle can maintain a speed of about 40 km/h (25 mph) or more without keeping your foot on the accelerator. Cruise control does not work at speeds below 40 km/h (25 mph). On vehicles with the Traction Control System (TCS) or the Stabilitrak® system may begin to limit wheel spin while you are using cruise control. If this happens, the cruise control will automatically disengage. See Traction Control System (TCS) on page 9‑34 or StabiliTrak® System on page 9‑36.

{ 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.

Object Detection Systems

Ultrasonic Parking Assist For vehicles with the Ultrasonic Rear Parking Assist (URPA) system, it assists the driver with parking and avoiding objects while in R (Reverse). URPA operates at speeds less than 8 km/h (5 mph), and the sensors on the rear bumper detect objects up to 1.5 m (5 ft) behind the vehicle, and at least 25 cm (10 in) off the ground.

{ WARNING

The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect:

. Objects that are below the bumper, under the vehicle, or too close or far from the vehicle.

. Children, pedestrians,

bicyclists, or pets.

If you do not use proper care before and while backing up, vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing up, be sure to look for objects and check the vehicle's mirrors.

How the System Works URPA comes on automatically when the shift lever is moved into R (Reverse). A single tone sounds to indicate the system is working. URPA operates only at speeds less than 8 km/h (5 mph). An obstacle is indicated by audible beeps. The interval between the beeps becomes shorter as the vehicle gets closer to the obstacle. When the distance is less than 30 cm (12 in) the beeps are continuous. To be detected, objects must be at least 25 cm (10 in) off the ground and below trunk level. Objects must also be within 1.5 m (5 ft) from the rear bumper. The distance at which objects can be detected may be less during warmer or humid weather.

Buick Regal Owner Manual - 2011

Black plate (43,1)

PARK ASSIST OFF displays on the Driver Information Center (DIC) to indicate that URPA is off. The message disappears after a short period of time. Turning the System On and Off The URPA system can be turned on and off using the park assist button located next to the radio.

The park assist button lights up when the system is on or in standby and turns off when it has been disabled. URPA defaults to the on setting each time the vehicle is started.

. An object was hanging out of the trunk during the last drive cycle. Once the object is removed and URPA detects no objects of interest, the URPA will return to normal operation. The vehicle's bumper is damaged. Take the vehicle to your dealer to repair the system.

. Other conditions, such as

vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.

If the system is still disabled after checking all conditions listed above and driving forward at least 40 km/h (25 mph), take the vehicle to your dealer.

If this

When the System Does Not Seem to Work Properly SERVICE PARK ASSIST: message occurs, take the vehicle to your dealer to repair the system. PARK ASSIST OFF: If the URPA system does not activate due to a temporary condition, the message displays on the DIC. See Driver Information Center (DIC) on page 5‑22 for more information. This can occur under the following conditions:

The driver has disabled the system. The ultrasonic sensors are not clean. Keep the vehicle's rear bumper free of mud, dirt, snow, ice, and slush. For cleaning instructions, see Exterior Care on page 10‑77.

Driving and Operating

Fuel Use of the recommended fuel is an important part of the proper maintenance of this vehicle. To help keep the engine clean and maintain optimum vehicle performance, we recommend the use of gasoline advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.

See Fuel E85 (85% Ethanol) on page 9‑47. For all other vehicles, use only the unleaded gasoline described under Recommended Fuel on page 9‑44.

Recommended Fuel If the vehicle has a 2.4L L4 engine (VIN Code C), use regular unleaded gasoline with a posted octane rating of 87 or higher. If the octane rating is less than 87, an audible knocking noise, commonly referred to as spark knock, might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.

The eighth digit of the Vehicle Identification Number (VIN) shows the code letter or number that identifies the vehicle's engine. The VIN is at the top left of the instrument panel. See Vehicle Identification Number (VIN) on page 12‑1. Vehicles that have a FlexFuel badge and a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85).

Buick Regal Owner Manual - 2011

Black plate (45,1)

If the vehicle has the 2.0L L4 engine (VIN Code V), use premium unleaded gasoline with a posted octane rating of 91 or higher. You can also use regular unleaded gasoline rated at 87 octane or higher, but the vehicle's acceleration could be slightly reduced, and a slight audible knocking noise, commonly referred to as spark knock, might be heard. If the octane is less than 87, a heavy knocking noise might be heard when driving. If this occurs, use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you could damage the engine. If heavy knocking is heard when using gasoline rated at 87 octane or higher, the engine needs service.

Driving and Operating

Gasoline Specifications (U.S. and Canada Only) At a minimum, gasoline should meet ASTM specification D 4814 in the United States or CAN/CGSB‐3.5 or 3.511 in Canada. Some gasolines contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT). We recommend against the use of gasolines containing MMT. See Fuel Additives on page 9‑46 for additional information.

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 might fail a smog‐check test. See Malfunction Indicator Lamp on page 5‑13. 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 might not be covered by the vehicle warranty.

Fuels in Foreign Countries Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel would not be covered by the vehicle warranty. To check the fuel availability, ask an auto club, or contact a major oil company that does business in the country where you will be driving.

Driving and Operating

Fuel Additives To provide cleaner air, all gasolines in the United States are now required to contain additives that help prevent engine and fuel system deposits from forming, allowing the emission control system to work properly. In most cases, nothing should have to be added to the fuel. However, some gasolines contain only the minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean and avoid problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Look for the TOP TIER label on the fuel pump to ensure gasoline meets enhanced detergency standards developed by the auto companies. A list of marketers providing TOP TIER Detergent Gasoline can be found at www.toptiergas.com.

For customers who do not use TOP TIER Detergent Gasoline regularly, one bottle of GM Fuel System Treatment PLUS, added to the fuel tank at every engine oil change, can help clean deposits from fuel injectors and intake valves. GM Fuel System Treatment PLUS is the only gasoline additive recommended by General Motors. It is available at your dealer. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines might be available in your area. We recommend that you use these gasolines, if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels.

Notice: This vehicle was not designed for fuel that contains methanol. 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 that are not reformulated for low emissions can contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask the attendant where you buy gasoline whether the fuel contains MMT. We recommend against the use of such gasolines. Fuels containing MMT can reduce spark plug life and affect emission control system performance. The malfunction indicator lamp might turn on. If this occurs, return to your dealer for service.

Fuel E85 (85% Ethanol) Vehicles that have a FlexFuel badge and a yellow fuel cap can use either unleaded gasoline or ethanol fuel containing up to 85% ethanol (E85). For all other vehicles, use only the unleaded gasoline described under Recommended Fuel on page 9‑44. We encourage the use of E85 in vehicles that are designed to use it. The ethanol in E85 is a “renewable” fuel, meaning it is made from renewable sources such as corn and other crops. Many service stations will not have an 85% ethanol fuel (E85) pump available. The U.S. Department of Energy has an alternative fuels website (www.afdc.energy.gov/afdc/ locator/stations/) that can help you find E85 fuel. Those stations that do have E85 should have a label indicating ethanol content. Do not use the fuel if the ethanol content is greater than 85%.

At a minimum, E85 should meet ASTM Specification D 5798 or CGSB Specification 3.512. Filling the tank with fuel mixtures that do not meet ASTM or CGSB specifications can affect driveability and could cause the malfunction indicator lamp to come on. As the outside temperature approaches freezing, ethanol fuel distributors should supply winter grade ethanol, the same as with unleaded gasoline. The starting characteristics of E85
fuel make it unsuitable for use when the ambient temperatures fall below −18°C (0°F). In the range of −18°C (0°F) to 0°C (32°F), you may experience an increase in the time it takes for the engine to start. It is best not to alternate repeatedly between gasoline and E85. If you do switch fuels, it is recommended that you add as much fuel as possible — do not add less than 11 L (3 gal) when refueling.

You should drive the vehicle immediately after refueling for at least 11 km (7 mi) to allow the vehicle to adapt to the change in ethanol concentration. E85 has less energy per liter (gallon) than gasoline, so you will need to refill the fuel tank more often when using E85 than when you are using gasoline. See Filling the Tank on page 9‑48. Notice: Some additives are not compatible with E85 fuel and can harm the vehicle's fuel system. Do not add anything to E85. Damage caused by additives would not be covered by the vehicle warranty. Notice: This vehicle was not designed for fuel that contains methanol. 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.

Filling the Tank

{ WARNING

Fuel vapor burns violently and a fuel fire can cause bad injuries. To help avoid injuries to you and others, read and follow all the instructions on the fuel pump island. Turn off the engine when refueling. Do not smoke near fuel or when refueling the vehicle. Do not use cellular phones. Keep sparks, flames, and smoking materials away from fuel. Do not leave the fuel pump unattended when refueling the vehicle. This is against the law in some places. Do not re-enter the vehicle while pumping fuel. Keep children away from the fuel pump; never let children pump fuel.

The tethered fuel cap is behind the fuel door on the vehicle's passenger side. The fuel door is unlocked when the vehicle is unlocked. Locking the vehicle locks the fuel door. Turn the fuel cap counterclockwise to remove. While refueling, hang the tethered fuel cap from the disk on the end of the fuel cap to the mating feature on the fuel door hinge. Reinstall the cap by turning it clockwise until it clicks.

{ WARNING

Fuel can spray out on you if you open the fuel cap too quickly. If you spill fuel and then something ignites it, you could be badly burned. This spray can happen if the tank is nearly full, and is more likely in hot weather. Open the fuel cap slowly and wait for any hiss noise to stop. Then unscrew the cap all the way.

Do not top off or overfill the tank. Wait a few seconds before removing the nozzle. Clean fuel from painted surfaces as soon as possible. See Exterior Care on page 10‑77.

. Bring the fill nozzle in contact

with the inside of the fill opening before operating the nozzle. Contact should be maintained until the filling is complete.

. Do not smoke while

pumping fuel.

. Do not use a cellular phone

while pumping fuel.

{ WARNING If a fire starts while you are refueling, do not remove the nozzle. Shut off the flow of fuel by shutting off the pump or by notifying the station attendant. Leave the area immediately.

Notice: If a new fuel cap is needed, be sure to get the right type of cap from your dealer. The wrong type of fuel cap might not fit properly, might cause the malfunction indicator lamp to light, and could damage the fuel tank and emissions system. See Malfunction Indicator Lamp on page 5‑13.

Filling a Portable Fuel Container

{ WARNING

Never fill a portable fuel container while it is in the vehicle. Static electricity discharge from the container can ignite the fuel vapor. You can be badly burned and the vehicle damaged if this occurs. To help avoid injury to you and others:

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.

Vehicle Care

10-9

. Always dispose of engine oil

properly. See “What to Do with Used Oil” in this section.

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 oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. See Engine Compartment Overview on page 10‑6 for the location of the engine oil dipstick. Obtaining an accurate oil level reading is essential: 1.

If the engine has been running recently, turn off the engine and allow several minutes for the oil to drain back into the oil pan. Checking the oil level too soon after engine shutoff will not provide an accurate oil level reading.

Buick Regal Owner Manual - 2011

Vehicle Care

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:

Specification (Except 2.0L Turbo Engine) Use and ask for engine oils with the dexos™ certification mark. Oils meeting the requirements of the vehicle should have the dexos certification mark on the container. This certification mark indicates that the oil has been approved to the dexos specification.

This vehicle was filled at the factory with dexos‐approved engine oil.

Buick Regal Owner Manual - 2011

Black plate (11,1)

Notice: Use only engine oil that is approved to the dexos specification or an equivalent engine oil of the appropriate viscosity grade. Engine oils approved to the dexos specification will show the dexos symbol on the container. Failure to use the recommended engine oil or equivalent can result in engine damage not covered by the vehicle warranty. If you are unsure whether the oil is approved to the dexos specification, ask your service provider. Use of Substitute Engine Oils if dexos is unavailable: In the event that dexos‐approved engine oil is not available at an oil change or for maintaining proper oil level, you may use substitute engine oil displaying the API Starburst symbol and of SAE 5W-30 viscosity grade. Use of oils that do not meet the dexos specification, however, may result in reduced performance under certain circumstances.

Specification (2.0L Turbo Engine) Use and ask for engine oils with the dexos certification mark. Oils meeting the requirements of the vehicle should have the dexos certification mark on the container. This certification mark indicates that the oil has been approved to the dexos specification.

oil or equivalent can result in engine damage not covered by the vehicle warranty. If you are unsure whether the oil is approved to the dexos specification, ask your service provider. Use of Substitute Engine Oils if dexos is unavailable for top‐up only: Engine oil not meeting the dexos specification or equivalent should not be used for an oil change. In the event that dexos‐approved engine oil is not available for maintaining proper oil level, however, you may use substitute engine oil displaying the API Starburst symbol and of SAE 5W-30 viscosity grade. Extensive use of oils that do not meet the dexos specification, however, may result in reduced performance or engine damage under certain circumstances.

Buick Regal Owner Manual - 2011

Black plate (12,1)

10-12

Vehicle Care

Maintaining the proper oil level is very important. However, if you use a substitute oil for any reason, we recommend that you perform a complete oil change back to dexos as soon as possible to protect the engine and maintain the engine's peak performance.

Viscosity Grade SAE 5W-30 is the best viscosity grade for the vehicle. Do not use other viscosity oils such as SAE 10W‐30, 10W‐40, or 20W-50.

(−20°F), an SAE 0W-30 oil should 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, be sure to always select an oil that meets the required specification, dexos. 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.

Cold Temperature Operation: In an area of extreme cold, where the temperature falls below −29°C

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.

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. Turn the ignition to ON/RUN with

the engine off.

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. 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 5‑28. 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

2. Press the DIC menu button on

the turn signal lever to enter the Vehicle Information Menu. Use the thumbwheel to scroll through the menu items until you reach REMAINING OIL LIFE.

3. Press the SET/CLR button to

reset the oil life at 100%.

4. Turn the ignition to LOCK/OFF. The system is reset when the CHANGE ENGINE OIL SOON message is off and the REMAINING OIL LIFE 100% message is displayed. If the CHANGE ENGINE OIL 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 service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, you should have this done at your dealer service department. Contact your dealer for additional information. The procedure can be found in the service manual. To purchase a service manual, see Service Publications Ordering Information on page 13‑11. Change the fluid and filter at the intervals listed in Scheduled Maintenance on page 11‑2, and be

sure to use the fluid listed in Recommended Fluids and Lubricants on page 11‑6.

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 service department and have it repaired as soon as possible. See Recommended Fluids and Lubricants on page 11‑6 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. Adding fluid will not correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

Buick Regal Owner Manual - 2011

Black plate (15,1)

When to Check and What to Use

The brake/hydraulic clutch fluid reservoir cap has this symbol on it. The common hydraulic clutch and brake master cylinder fluid reservoir is filled with either DOT 3 or DOT 4
brake fluid as indicated on the reservoir cap. See Engine Compartment Overview on page 10‑6 for reservoir location. 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 See Engine Compartment Overview on page 10‑6 for the location of the engine air cleaner/filter. When to Inspect the Engine Air Cleaner/Filter Inspect the air cleaner/filter at the scheduled maintenance intervals and replace it at the first oil change after each 80 000 km (50,000 mile) interval. See Scheduled Maintenance on page 11‑2 for more information. 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 air cleaner/filter, remove the filter from the vehicle and lightly shake the filter to release

{ WARNING

Heater and radiator hoses, and other engine parts, can be very hot. Do not touch them. If you do, you can be burned. Do not run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

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.

Buick Regal Owner Manual - 2011

Vehicle Care

Engine Coolant The cooling system in the vehicle is filled with DEX-COOL® engine coolant. This coolant is designed to remain in the vehicle for 5 years or 240 000 km (150,000 miles), 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 10‑21.

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.

Buick Regal Owner Manual - 2011

Black plate (19,1)

Notice: If an improper coolant mixture is used, the engine could overheat and be badly damaged. The repair cost would not be covered by the vehicle warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core, and other parts.

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.

Vehicle Care

10-19

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 the indicated 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. The coolant surge tank is located in the engine compartment on the driver side of the vehicle. See Engine Compartment Overview on page 10‑6 for more information on location.
