transmission may shift firmly. This operation is considered normal and will not affect function or durability of the transmission. Over time the adaptive learning process will fully update transmission operation to its optimum shift feel. If the battery has been disconnected or a new battery has been installed, the clock and the preset radio stations must be reset once the battery is reconnected. • Always dispose of automotive batteries in a responsible manner. Follow your local authorized standards for disposal. Call your local authorized recycling center to find out more about recycling automotive batteries.

RECYCLE

ENGINE COOLANT

Checking engine coolant The concentration and level of engine coolant should be checked at the intervals listed in scheduled maintenance information. The coolant concentration should be maintained at 50/50 coolant and distilled water, which equates to a freeze point of -34°F (-36°C). Coolant concentration testing is possible with a hydrometer or antifreeze tester. The level of coolant should be maintained at the FULL COLD level or within the COLD FILL RANGE in the coolant reservoir. If the level falls below, add coolant per the instructions in the Adding engine coolant section. Your vehicle was factory-filled with a 50/50 engine coolant and water concentration. If the concentration of coolant falls below 40% or above 60%, the engine parts could become damaged or not work properly. A 50/50 mixture of coolant and water provides the following: • Freeze protection down to -34°F (-36°C). • Boiling protection up to 265°F (129°C). • Protection against rust and other forms of corrosion. • Proper function of calibrated gauges.

271

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

When the engine is cold, check the level of the engine coolant in the reservoir.

• The engine coolant should be at the FULL COLD level or within the

COLD FILL RANGE as listed on the engine coolant reservoir (depending upon application).

• Refer to scheduled maintenance information for service interval

schedules.

If the engine coolant has not been checked at the recommended interval, the engine coolant reservoir may become low or empty. If the reservoir is low or empty, add engine coolant to the reservoir. Refer to Adding engine coolant in this chapter. Note: Automotive fluids are not interchangeable; do not use engine coolant/antifreeze or windshield washer fluid outside of its specified function and vehicle location.

Adding engine coolant When adding coolant, make sure it is a 50/50 mixture of engine coolant and distilled water. Add the mixture to the coolant reservoir, when the engine is cool, until the appropriate fill level is obtained. If coolant is filled to the COLD FILL RANGE or FULL COLD level when the engine is not cool, the system will remain underfilled.

WARNING: Do not add engine coolant when the engine is hot. Steam and scalding liquids released from a hot cooling system

can burn you badly. Also, you can be burned if you spill coolant on hot engine parts.

272

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

WARNING: Do not put engine coolant in the windshield washer fluid container. If sprayed on the windshield, engine coolant

could make it difficult to see through the windshield. • DO NOT MIX different colors or types of coolant in your vehicle. Make sure the correct coolant is used. DO NOT MIX recycled coolant and new (unused) coolant together in the vehicle. Mixing of engine coolants may harm your engine’s cooling system. The use of an improper coolant may harm engine and cooling system components and may void the warranty. Refer to Maintenance product specifications and capacities in this chapter.

Note: Do not use stop leak pellets or cooling system sealants/additives as they can cause damage to the engine cooling and/or heating systems. This damage would not be covered under your vehicle’s warranty. • A large amount of water without engine coolant may be added, in case of emergency, to reach a vehicle service location. In this instance, the cooling system must be drained and refilled with a 50/50 mixture of engine coolant and distilled water as soon as possible. Water alone (without engine coolant) can cause engine damage from corrosion, overheating or freezing. • Do not use alcohol, methanol, brine or any engine coolants mixed with alcohol or methanol antifreeze (coolant). Alcohol and other liquids can cause engine damage from overheating or freezing.

• Do not add extra inhibitors or additives to the coolant. These

can be harmful and compromise the corrosion protection of the engine coolant.

For vehicles with overflow coolant systems with a non-pressurized cap on the coolant recovery system, add coolant to the coolant recovery reservoir when the engine is cool. Add the proper mixture of coolant and water to the FULL COLD level. For all other vehicles which have a coolant degas system with a pressurized cap, or if it is necessary to remove the coolant pressure relief cap on the radiator of a vehicle with an overflow system, follow these steps to add engine coolant.

WARNING: To reduce the risk of personal injury, make sure the engine is cool before unscrewing the coolant pressure relief cap. The cooling system is under pressure; steam and hot liquid can come out forcefully when the cap is loosened slightly.

273

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

Add the proper mixture of coolant and water to the cooling system by following these steps: 1. Before you begin, turn the engine off and let it cool. 2. When the engine is cool, wrap a thick cloth around the coolant pressure relief cap on the coolant reservoir (a translucent plastic bottle). Slowly turn cap counterclockwise (left) until pressure begins to release. 3. Step back while the pressure releases. 4. When you are sure that all the pressure has been released, use the cloth to turn it counterclockwise and remove the cap. 5. Fill the coolant reservoir slowly with the proper coolant mixture, to within the COLD FILL RANGE or the FULL COLD level on the reservoir. If you removed the radiator cap in an overflow system, fill the radiator until the coolant is visible and radiator is almost full. 6. Replace the cap. Turn until tightly installed. Cap must be tightly installed to prevent coolant loss. After any coolant has been added, check the coolant concentration (refer to Checking engine coolant). If the concentration is not 50/50
(protection to –34°F/–36°C), drain some coolant and adjust the concentration. It may take several drains and additions to obtain a 50/50
coolant concentration. Whenever coolant has been added, the coolant level in the coolant reservoir should be checked the next few times you drive the vehicle. If necessary, add enough 50/50 concentration of engine coolant and distilled water to bring the liquid level to the proper level. If you have to add more than 1.0 quart (1.0 liter) of engine coolant per month, have your authorized dealer check the engine cooling system. Your cooling system may have a leak. Operating an engine with a low level of coolant can result in engine overheating and possible engine damage.

Recycled engine coolant Ford Motor Company does NOT recommend the use of recycled engine coolant since a Ford-approved recycling process is not yet available.

Used engine coolant should be disposed of in an appropriate

manner. Follow your community’s regulations and standards for recycling and disposing of automotive fluids.

Coolant refill capacity To find out how much fluid your vehicle’s cooling system can hold, refer to Maintenance product specifications and capacities in this chapter. 274

above 50%.

Severe climates If you drive in extremely cold climates (less than –34°F [–36°C]): • It may be necessary to increase the coolant concentration • NEVER increase the coolant concentration above 60%. Increased engine coolant concentrations above 60% will decrease the overheat protection characteristics of the engine coolant and may cause engine damage.

• Refer to the chart on the coolant container to ensure the

coolant concentration in your vehicle will provide adequate freeze protection at the temperatures in which you drive in the winter months.

above 40%.

If you drive in extremely hot climates: • It is still necessary to maintain the coolant concentration • NEVER decrease the coolant concentration below 40%. Decreased engine coolant concentrations below 40% will decrease the corrosion/freeze protection characteristics of the engine coolant and may cause engine damage.

• Refer to the chart on the coolant container to ensure the

coolant concentration in your vehicle will provide adequate protection at the temperatures in which you drive.

Vehicles driven year-round in non-extreme climates should use a 50/50
mixture of engine coolant and distilled water for optimum cooling system and engine protection.

What you should know about fail-safe cooling (4.6L V8 engine only) If the engine coolant supply is depleted, this feature allows the vehicle to be driven temporarily before incremental component damage is incurred. The “fail-safe” distance depends on ambient temperatures, vehicle load and terrain. How fail-safe cooling works If the engine begins to overheat: • The engine coolant temperature gauge

will move to the red (hot)

area.

275

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications • The engine coolant temperature indicator will illuminate. • The service engine soon indicator light will illuminate. If the engine reaches a preset over-temperature condition, the engine will automatically switch to alternating cylinder operation. Each disabled cylinder acts as an air pump and cools the engine. When this occurs the vehicle will still operate. However: • The engine power will be limited. • The air conditioning system will be disabled. Continued operation will increase the engine temperature: • The engine will completely shut down. • Steering and braking effort will increase. Once the engine temperature cools, the engine can be re-started. Take your vehicle to an authorized dealer as soon as possible to minimize engine damage. When fail-safe mode is activated You have limited engine power when in the fail-safe mode, so drive the vehicle with caution. The vehicle will not be able to maintain high speed operation and the engine will run rough. Remember that the engine is capable of completely shutting down automatically to prevent engine damage, therefore: 1. Pull off the road as soon as safely possible and turn off the engine. 2. Arrange for the vehicle to be taken to an authorized dealer. 3. If this is not possible, wait a short period for the engine to cool. 4. Check the coolant level and replenish if low.

WARNING: Fail-safe mode is for use during emergencies only. Operate the vehicle in fail-safe mode only as long as necessary to bring the vehicle to rest in a safe location and seek immediate repairs. When in fail-safe mode, the vehicle will have limited power, will not be able to maintain high-speed operation, and may completely shut down without warning, potentially losing engine power, power steering assist, and power brake assist, which may increase the possibility of a crash resulting in serious injury.

WARNING: Never remove the coolant reservoir cap while the engine is running or hot.

5. Restart the engine and take your vehicle to an authorized dealer. Driving the vehicle without repairing the engine problem increases the chance of engine damage. Take your vehicle to an authorized dealer as soon as possible.

FUEL FILTER For fuel filter replacement, see your authorized dealer. Refer to scheduled maintenance information for the appropriate intervals for changing the fuel filter. Replace the fuel filter with an authorized Motorcraft威 part. The customer warranty may be void for any damage to the fuel system if an authorized Motorcraft威 fuel filter is not used.

WHAT YOU SHOULD KNOW ABOUT AUTOMOTIVE FUELS

Important safety precautions

WARNING: Do not overfill the fuel tank. The pressure in an overfilled tank may cause leakage and lead to fuel spray and fire.

WARNING: The fuel system may be under pressure. If you hear a hissing sound near the fuel filler door (Easy Fuel™ “no cap” fuel system), do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury.

WARNING: Automotive fuels can cause serious injury or death if misused or mishandled.

WARNING: Gasoline may contain benzene, which is a cancer-causing agent.

Observe the following guidelines when handling automotive fuel: • Extinguish all smoking materials

and any open flames before refueling your vehicle.

Maintenance and Specifications

swallowed can cause death or permanent injury. If fuel is swallowed, call a physician immediately, even if no symptoms are immediately apparent. The toxic effects of fuel may not be visible for hours. • Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind

can lead to eye and respiratory tract irritation. In severe cases, excessive or prolonged breathing of fuel vapor can cause serious illness and permanent injury.

• Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes, remove contact lenses (if worn), flush with water for 15 minutes and seek medical attention. Failure to seek proper medical attention could lead to permanent injury.

• Fuels can also be harmful if absorbed through the skin. If fuel is

splashed on the skin and/or clothing, promptly remove contaminated clothing and wash skin thoroughly with soap and water. Repeated or prolonged skin contact with fuel liquid or vapor causes skin irritation. • Be particularly careful if you are taking “Antabuse” or other forms of disulfiram for the treatment of alcoholism. Breathing gasoline vapors, or skin contact could cause an adverse reaction. In sensitive individuals, serious personal injury or sickness may result. If fuel is splashed on the skin, promptly wash skin thoroughly with soap and water. Consult a physician immediately if you experience an adverse reaction.

WARNING: When refueling always shut the engine off and never allow sparks or open flames near the filler neck. Never

smoke while refueling. Fuel vapor is extremely hazardous under certain conditions. Care should be taken to avoid inhaling excess fumes.

WARNING: The flow of fuel through a fuel pump nozzle can produce static electricity, which can cause a fire if fuel is

pumped into an ungrounded fuel container.

Easy Fuel™ “no cap” fuel system Your fuel tank is equipped with an Easy Fuel™ “no cap” fuel filler system. This allows you to simply open the fuel filler door and insert the fuel filler nozzle into the fuel system. The Easy Fuel™ system is self-sealing and protected against dust, dirt, water and snow/ice. When fueling your vehicle: 1. Turn the engine off. 2. Open the fuel filler door. 3. Slowly insert the fuel filler nozzle fully into the fuel system. Pump fuel as normal. 4. After you are done pumping fuel, wait about five seconds before slowly removing the fuel filler nozzle. This allows residual fuel to drain back into the fuel tank and not spill onto the vehicle.

279

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

Note: A fuel spillage concern may occur if overfilling the fuel tank. Do not overfill the tank to the point that the fuel is able to bypass the fuel filler nozzle. The overfilled fuel may run down the drain located within the fuel filler housing and to the ground. If the check fuel fill inlet light or CHECK FUEL FILL INLET message comes on, the fuel fill inlet may not have properly closed. The inlet may have stuck open or debris may be preventing the inlet from fully closing. At the next opportunity, safely pull off the road, turn off the engine, open the fuel filler door and remove any visible debris from the fuel fill opening. Insert either the fuel fill nozzle or the fuel fill funnel (see Refilling with a portable fuel container for funnel location) provided with the vehicle several times to dislodge any debris and/or allow the inlet to close properly. If this action corrects the problem, the check fuel fill inlet light or CHECK FUEL FILL INLET message may not reset immediately. It may take several driving cycles for the check fuel fill inlet light or CHECK FUEL FILL INLET message to turn off. A driving cycle consists of an engine start-up (after four or more hours with the engine off) followed by city/highway driving. Continuing to drive with the check fuel fill inlet light or CHECK FUEL FILL INLET message on may cause the service engine soon lamp to turn on as well.

WARNING: The fuel system may be under pressure. If you hear a hissing sound near the fuel filler door (Easy Fuel™ “no cap” fuel system), do not refuel until the sound stops. Otherwise, fuel may spray out, which could cause serious personal injury.

Choosing the right fuel Use only UNLEADED fuel or UNLEADED fuel blended with a maximum of 10% ethanol. Do not use fuel ethanol (E85), diesel, methanol, leaded fuel or any other fuel. The use of leaded fuel is prohibited by law and could damage your vehicle. 280

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

Your vehicle was not designed to use fuel or fuel additives with metallic compounds, including manganese-based additives. Note: Use of any fuel other than those recommended may cause powertrain damage, a loss of vehicle performance, and repairs may not be covered under warranty.

87(R+M)/2 METHOD

Octane recommendations Your vehicle is designed to use “Regular” unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as “Regular” with an octane rating below 87, particularly in high altitude areas. Fuels with octane levels below 87 are not recommended. Do not be concerned if your engine sometimes knocks lightly. However, if it knocks heavily under most driving conditions while you are using fuel with the recommended octane rating, see your authorized dealer to prevent any engine damage. Octane recommendations (4.6L V8 engine) Your vehicle will run normally on 87 octane regular fuel without damaging the engine, but premium fuel with an octane rating of 91
(R+M)/2 or higher is recommended for best overall performance. For Shelby GT500 octane requirements, see the Shelby GT500
Supplement.

Fuel quality If you are experiencing starting, rough idle or hesitation driveability problems during a cold start, try a different brand of “Regular” unleaded gasoline. Premium unleaded gasoline is not recommended for vehicles designed to use “Regular” unleaded gasoline because it may cause these problems to become more pronounced. If the problems persist, see your authorized dealer. Do not add aftermarket fuel additive products to your fuel tank. It should not be necessary to add any aftermarket products to your fuel tank if you continue to use high quality fuel of the recommended octane rating. These products have not been approved for your engine and could cause damage to the fuel system. Repairs to correct the effects of using an aftermarket product in your fuel may not be covered by your warranty. Many of the world’s automakers approved the World-Wide Fuel Charter that recommends gasoline specifications to provide improved

281

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

performance and emission control system protection for your vehicle. Gasolines that meet the World-Wide Fuel Charter should be used when available. Ask your fuel supplier about gasolines that meet the World-Wide Fuel Charter.

Cleaner air Ford endorses the use of reformulated “cleaner-burning” gasolines to improve air quality, per the recommendations in the Choosing the right fuel section.

Running out of fuel Avoid running out of fuel because this situation may have an adverse effect on powertrain components. If you have run out of fuel: • You may need to cycle the ignition from off to on several times after refueling to allow the fuel system to pump the fuel from the tank to the engine. On restarting, cranking time will take a few seconds longer than normal.

• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the

engine. If the vehicle is out of fuel and on a steep grade, more than 1 gallon (3.8L) may be required.

Refilling with a portable fuel container With the Easy Fuel™ “no cap” fuel system, use the following directions when filling from a portable fuel container:

WARNING: Do not insert the nozzle of portable fuel containers or aftermarket funnels into the Easy Fuel™ system. This could damage the fuel system and its seal, and may cause fuel to run onto the ground instead of filling the tank, which could result in serious personal injury.

WARNING: Do not try to pry open or push open the Easy Fuel™ system with foreign objects. This could damage the fuel

system and its seal and cause injury to you or others.

When filling the vehicle’s fuel tank from a portable fuel container, use the funnel included with the vehicle. 282

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

1. Locate the white plastic funnel. It is included with the tire changing tools. (For vehicles equipped with the temporary mobility kit, the funnel is located in the spare tire well in the trunk).

2. Slowly insert the funnel into the Easy Fuel™ system. 3. Fill the vehicle with fuel from the portable fuel container. 4. When done, clean the funnel or properly dispose of it. Extra funnels can be purchased from your authorized dealer if you choose to dispose of the funnel. Do not use aftermarket funnels; they will not work with the Easy Fuel™ system and can damage it. The included funnel has been specially designed to work safely with your vehicle.

ESSENTIALS OF GOOD FUEL ECONOMY

Measuring techniques Your best source of information about actual fuel economy is you, the driver. You must gather information as accurately and consistently as possible. Fuel expense, frequency of fill-ups or fuel gauge readings are NOT accurate as a measure of fuel economy. We do not recommend taking fuel economy measurements during the first 1,000 miles (1,600 km) of driving (engine break-in period). You will get a more accurate measurement after 2,000 miles–3,000 miles (3,000 km–5,000 km).

Filling the tank The advertised fuel capacity of the fuel tank on your vehicle is equal to the rated refill capacity of the fuel tank as listed in the Maintenance product specifications and capacities section of this chapter. The advertised capacity is the amount of the indicated capacity and the empty reserve combined. Indicated capacity is the difference in the amount of fuel in a full tank and a tank when the fuel gauge indicates empty. Empty reserve is the small amount of fuel remaining in the fuel tank after the fuel gauge indicates empty.

283

2010 05+ Mustang (197) Owners Guide, 3rd Printing USA (fus)

Maintenance and Specifications

an error in the reading will result if the engine is left running.

The amount of usable fuel in the empty reserve varies and should not be relied upon to increase driving range. When refueling your vehicle after the fuel gauge indicates empty, you might not be able to refuel the full amount of the advertised capacity of the fuel tank due to the empty reserve still present in the tank. For consistent results when filling the fuel tank: • Turn the engine/ignition switch to the off position prior to refueling, • Use the same filling rate setting (low — medium — high) each time • Allow no more than two automatic click-offs when filling. • Always use fuel with the recommended octane rating. • Use a known quality gasoline, preferably a national brand. • Use the same side of the same pump and have the vehicle facing the • Have the vehicle loading and distribution the same every time. Your results will be most accurate if your filling method is consistent.

same direction each time you fill up.

the tank is filled.

Calculating fuel economy 1. Fill the fuel tank completely and record the initial odometer reading (in miles or kilometers). 2. Each time you fill the tank, record the amount of fuel added (in gallons or liters). 3. After at least three to five tank fill-ups, fill the fuel tank and record the current odometer reading. 4. Subtract your initial odometer reading from the current odometer reading. 5. Follow one of the simple calculations in order to determine fuel economy:

Calculation 1: Divide total miles traveled by total gallons used. Calculation 2: Multiply liters used by 100, then divide by total kilometers traveled.

Keep a record for at least one month and record the type of driving (city or highway). This will provide an accurate estimate of the vehicle’s fuel economy under current driving conditions. Additionally, keeping records during summer and winter will show how temperature impacts fuel economy. In general, lower temperatures give lower fuel economy. 284

WARNING: Exhaust leaks may result in entry of harmful and potentially lethal fumes into the passenger compartment.

Do not make any unauthorized changes to your vehicle or engine. By law, vehicle owners and anyone who manufactures, repairs, services, sells, leases, trades vehicles, or supervises a fleet of vehicles are not permitted to intentionally remove an emission control device or prevent it from working. Information about your vehicle’s emission system is on the Vehicle Emission Control Information Decal located on or near the engine. This decal also lists engine displacement. Please consult your Warranty Guide/Customer Information Guide for complete emission warranty information.

On-board diagnostics (OBD-II) Your vehicle is equipped with a computer that monitors the engine’s emission control system. This system is commonly known as the on-board diagnostics system (OBD-II). The OBD-II system protects the environment by ensuring that your vehicle continues to meet government emission standards. The OBD-II system also assists your authorized dealer in properly servicing your vehicle. When the service engine soon a malfunction. Temporary malfunctions may cause the service engine soon 1.

3. The fuel fill inlet may not have been properly closed. See Easy Fuel™ “no cap” fuel system in this chapter. 4. Driving through deep water—the electrical system may be wet. These temporary malfunctions can be corrected by filling the fuel tank with good quality fuel, properly closing the fuel fill inlet or letting the electrical system dry out. After three driving cycles without these or any other temporary malfunctions present, the service engine soon indicator should stay off the next time the engine is started. A driving cycle consists of a cold engine startup followed by mixed city/highway driving. No additional vehicle service is required. If the service engine soon indicator remains on, have your vehicle serviced at the first available opportunity. Although some malfunctions detected by the OBD-II may not have symptoms that are apparent, indicator on can continued driving with the service engine soon result in increased emissions, lower fuel economy, reduced engine and transmission smoothness, and lead to more costly repairs.

Readiness for Inspection/Maintenance (I/M) testing Some state/provincial and local governments may have Inspection/Maintenance (I/M) programs to inspect the emission control equipment on your vehicle. Failure to pass this inspection could prevent you from getting a vehicle registration. Your vehicle may not pass the I/M test if the service engine soon properly (bulb is burned out), or if the OBD-II system has determined that some of the emission control systems have not been properly checked. In this case, the vehicle is considered not ready for I/M testing. If the service engine soon work, the vehicle may need to be serviced. Refer to On-board diagnostics (OBD-II) in this chapter. If the vehicle’s engine or transmission has just been serviced, or the battery has recently run down or been replaced, the OBD-II system may indicate that the vehicle is not ready for I/M testing. To determine if the vehicle is ready for I/M testing, turn the ignition key to the on position for 15 seconds without cranking the engine. If the service engine soon ready for I/M testing; if the service engine soon solid, it means that the vehicle is ready for I/M testing. The OBD-II system is designed to check the emission control system during normal driving. A complete check may take several days. If the 288

vehicle is not ready for I/M testing, the following driving cycle consisting of mixed city and highway driving may be performed: 15 minutes of steady driving on an expressway/highway followed by 20 minutes of stop-and-go driving with at least four 30-second idle periods. Allow the vehicle to sit for at least eight hours without starting the engine. Then, start the engine and complete the above driving cycle. The engine must warm up to its normal operating temperature. Once started, do not turn off the engine until the above driving cycle is complete. If the vehicle is still not ready for I/M testing, the above driving cycle will have to be repeated.

POWER STEERING FLUID Check the power steering fluid. Refer to the scheduled maintenance guide for the service interval schedules. 1. Start the engine and let it run until it reaches normal operating temperature (the engine coolant temperature gauge indicator will be near the center of the normal area between H and C). 2. While the engine idles, turn the steering wheel to its furthest point (until it stops) left and right several times. 3. Turn the engine off. 4. Check the fluid level in the reservoir. It should be between the MIN and MAX lines. Do not add fluid if the level is in this range. 5. If the fluid is low, add fluid in small amounts, continuously checking the level until it reaches the range between the MIN and MAX lines. Be sure to put the cap back on the reservoir. Refer to Maintenance product specifications and capacities in this chapter for the proper fluid type.

BRAKE/CLUTCH FLUID Brake and clutch systems are supplied from the same reservoir.

Maintenance and Specifications

The fluid level will drop slowly as the brakes wear, and will rise when the brake components are replaced. Fluid levels between the MIN and MAX lines are within the normal operating range; there is no need to add fluid. If the fluid levels are outside of the normal operating range, the performance of the system could be compromised; seek service from your authorized dealer immediately.

TRANSMISSION FLUID

Checking automatic transmission fluid The 5R55S transmission does not have a transmission fluid dipstick. Refer to your scheduled maintenance information for scheduled intervals for fluid checks and changes. Your transmission does not consume fluid. However, the fluid level should be checked if the transmission is not working properly, i.e., if the transmission slips or shifts slowly or if you notice some sign of fluid leakage. Transmission fluid should be checked and, if required, fluid should be added by an authorized dealer. Before adding any fluid, make sure the correct type is used. Use only MERCON威 V automatic transmission fluid. The type of fluid used is indicated on the transmission fluid pan, extension housing. Refer to Maintenance product specifications and capacities in this chapter. Use of a non-approved automatic transmission fluid may cause internal transmission component damage and void the warranty. Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components.
