This can lead to serious mechanical problems because you will no longer have an accurate record of when maintenance is needed. We recommend using Acura parts and fluids whenever you have maintenance done. These are manufactured to the same high- quality standards as the original components, so you can be confident of their performance and durability. Your authorized dealer knows your vehicle best and can provide competent, efficient service. However, service at a dealer is not mandatory to keep your warranties in effect. Maintenance may be done by any qualified service facility or person who is skilled in this type of automotive service. Keep all receipts as proof of completion, and have the person who does the work fill out your Maintenance Journal or Canadian Maintenance Log. Check your warranty booklet for more information. 506 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu U.S. Vehicles: According to state and federal regulations, failure to perform maintenance on the items marked with ＃ will not void your emissions warranties. However, Acura recommends that all maintenance services be performed in accordance with the intervals indicated by the multi-information display. Owner's Maintenance Checks You should check the following items at the specified intervals. If you are unsure of how to perform any check, turn to the appropriate page listed. ● Engine oil level － Check every time you fill the fuel tank. See page 422. ● Engine coolant level － Check the radiator reserve tank every time you fill the fuel tank. See page 422. ● Automatic transmission － Check the fluid level monthly. See page page 517. ● Brakes － Check the fluid level monthly. See page 519. ● Tires － Check the tire pressure monthly. Examine the tread for wear and foreign objects. See page 535. Maintenance MinderTM ● Lights － Check the operation of the headlights, parking lights, taillights, high-mount brake light, and license plate lights monthly. See page 521. 507 2011 MDXMaintenance Main Items Symbol Maintenance Sub Items 10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Maintenance MinderTM Symbol ● Replace engine oil1 ● Replace engine oil1 and oil filter ● Inspect front and rear brakes ● Check parking brake adjustment ● Inspect these items: ● Tie rod ends, steering gear box, and boots ● Suspension components ● Driveshaft boots ● Brake hoses and lines (including ABS/VSA) ● All fluid levels and condition of fluids ● Exhaust system＃ ● Fuel lines and connections＃ 1: If the message ‘‘SERVICE DUE NOW’’ does not appear more than 12 months after the display is reset, change the engine oil every year. ＃: See information on maintenance and emissions warranty in the first column on page 506.

Inspect the cooling system for leaks. 514 water. Always use Honda Long-life Anti- freeze/Coolant Type 2. This coolant is pre-mixed with 50 percent antifreeze and 50 percent water. Never add straight antifreeze or plain If Honda antifreeze/coolant is not available, you may use another major-brand non-silicate coolant as a temporary replacement. Make sure it is a high-quality coolant recommended for aluminum engines. Continued use of any non- Honda coolant can result in corrosion, causing the cooling system to malfunction or fail. Have the cooling system flushed and refilled with Honda antifreeze/ coolant as soon as possible. If the reserve tank is completely empty, you should also check the coolant level in the radiator. Removing the radiator cap while the engine is hot can cause the coolant to spray out, seriously scalding you. Always let the engine and radiator cool down before removing the radiator cap. 2011 MDX 10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu RADIATOR CAP COVER RADIATOR CAP 1.

Antifreeze can damage your vehicle's paint, while a vinegar/water solution can damage the windshield washer pump. Use only commercially-available windshield washer fluid. Windshield Washers Check the fluid level in the windshield washer reservoir at least monthly during normal use. If the washer fluid is low, a ‘‘LOW WASHER FLUID’’ message appears on the multi-information display. Fill the reservoir with a good-quality windshield washer fluid. This increases the cleaning capability and prevents freezing in cold weather. When you refill the reservoir, clean the edges of the windshield wiper blades with windshield washer fluid on a clean cloth. This will help to condition the blade edges. MAX RESERVE TANK MIN 6. Pour coolant into the reserve tank. Fill it to halfway between the MAX and MIN marks. Put the cap back on the reserve tank. Do not add any rust inhibitors or other additives to your vehicle's cooling system. They may not be compatible with the coolant or engine components. 516 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Check the fluid level with the engine at normal operating temperature. 1.

Check the fluid level in the brake fluid reservoir monthly. Always use Honda Heavy Duty Brake Fluid DOT 3. If it is not available, you should use only DOT 3 or DOT 4 fluid, from a sealed container, as a temporary replacement. Using any non-Honda brake fluid can cause corrosion and decrease the life of the system. Have the brake system flushed and refilled with Honda Heavy Duty Brake Fluid DOT 3 as soon as possible. Brake fluid marked DOT 5 is not compatible with your vehicle's braking system and can cause extensive damage. Brake Fluid MIN MAX The fluid level should be between the MIN and MAX marks on the side of the reservoir. If the level is at or below the MIN mark, your brake system needs attention. Have the brake system inspected for leaks or worn brake pads. 519 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Power Steering Fluid, Timing Belt Always use Acura Power Steering Fluid. You may use another power steering fluid as an emergency replacement, but have the power steering system flushed and refilled with Acura PSF as soon as possible. A low power steering fluid level can indicate a leak in the system. Check the fluid level frequently, and have the system inspected as soon as possible. If you are not sure how to add fluid, contact your dealer. Turning the steering wheel to full left or right lock and holding it there can damage the power steering pump. Timing Belt The timing belt should be replaced at the intervals shown in the Maintenance Minder schedule. Replace the timing belt every 60,000 miles (U.S.) or every 100,000 km (Canada) if you regularly drive your vehicle in any of the following conditions: ● In very high temperatures (over 110°F, 43°C). ● In very low temperatures (under －20°F, －29°C). ● Frequently tow a trailer. Power Steering Fluid UPPER LEVEL LOWER LEVEL Check the level on the side of the reservoir when the engine is cold. The fluid should be between the UPPER LEVEL and LOWER LEVEL.

Wiper Blades 533 2011 MDXUse a gauge to measure the air pressure in each tire at least once a month. Even tires that are in good condition may lose 1 to 2 psi (10 to 20 kPa, 0.1 to 0.2 kgf/cm2) per month. Remember to check the spare tire at the same time. 10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Tires To safely operate your vehicle, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated. The following pages give more detailed information on how to take care of your tires and what to do when they need to be replaced. Using tires that are excessively worn or improperly inflated can cause a crash in which you can be seriously hurt or killed. Follow all instructions in this owner's manual regarding tire inflation and maintenance. 534 Inflation Guidelines Keeping the tires properly inflated provides the best combination of handling, tread life, and riding comfort. ● Underinflated tires wear unevenly, adversely affect handling and fuel economy, and are more likely to fail from being overheated. ● Overinflated tires can make your vehicle ride more harshly, are more prone to damage from road hazards, and wear unevenly. The tire pressure monitoring system (TPMS) warns you when a tire pressure is low. See page 449 for more information. Even though your vehicle is equipped with TPMS, we recommend that you visually check your tires every day. If you think a tire might be low, check it immediately with a tire gauge. 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Check the air pressures when the tires are cold. This means the vehicle has been parked for at least 3 hours, or driven less than 1 mile (1.6 km). Add or release air, if needed, to match the recommended cold tire pressures. If you check air pressures when the tires are hot [driven for several miles (kilometers)], you will see readings 4 to 6 psi (30 to 40 kPa, 0.3 to 0.4 kgf/cm2) higher than the cold readings. This is normal. Do not let air out to match the recommended cold air pressure. The tire will be underinflated. While tubeless tires have some ability to self-seal if they are punctured, you should look closely for punctures if a tire starts losing pressure. You should get your own tire pressure gauge and use it whenever you check your tire pressures. This will make it easier for you to tell if a pressure loss is due to a tire problem and not due to a variation between gauges. Recommended Tire Pressures The following chart shows the recommended cold tire pressures for most normal driving conditions. MDX,TechnologyPackage,andU.S. TechnologyPackagewithEntertainment models Tire Size P255/55R18 104H Cold Tire Pressure for Normal Driving Front/Rear: 32 psi (220 kPa, 2.2 kgf/cm2) Tires U.S.AdvancePackage,Advance PackagewithEntertainment,and CanadianElitePackagemodels Tire Size P255/50R19 103H Cold Tire Pressure for Normal Driving Front/Rear: 32 psi (220 kPa, 2.2 kgf/cm2) The compact spare tire pressure is: 60 psi (420 kPa, 4.2 kgf/cm2) For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver's doorjamb.

CONTINUED 535 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Tires High Speed Driving We strongly recommend that you do not drive faster than the posted speed limits and conditions allow. If you ever drive in a sanctioned competitive event at sustained high speeds (over 99 mph or 160 km/h), be sure to adjust the cold tire pressures as shown below. If you do not, excessive heat can build up and cause sudden tire failure. U.S.AdvancePackage,Advance PackagewithEntertainment,and CanadianElitePackagemodels Tire Size P255/50R19 103H Cold Tire Pressure for High Speed Driving Front: 33 psi (230 kPa, 2.3 kgf/cm2) Rear: 36 psi (260 kPa, 2.6 kgf/cm2) 536 Tire Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear. You should look for: ● Bumps or bulges in the tread or side of the tire. Replace the tire if you find either of these conditions. ● Cuts, splits, or cracks in the side of the tire. Replace the tire if you can see fabric or cord. ● Excessive tread wear. INDICATOR LOCATION MARKS TREAD WEAR INDICATORS Your tires have wear indicators molded into the tread. When the tread wears down, you will see a 1/2 inch (12.7 mm) wide band across the tread. This shows there is less than 1/16 inch (1.6 mm) of tread left on the tire. A tire this worn gives very little traction on wet roads. You should replace the tire if you can see three or more tread wear indicators. 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Tire Service Life The service life of your tires is dependent on many factors, including, but not limited to, driving habits, road conditions, vehicle loading, inflation pressure, maintenance history, speed, and environmental conditions (even when the tires are not in use). In addition to your regular inspections and inflation pressure maintenance, it is recommended that you have annual inspections performed once the tires reach five years old. It is also recommended that all tires, including the spare, be removed from service after 10 years from the date of manufacture, regardless of their condition or state of wear. Tires The last four digits of the TIN (tire identification number) are found on the sidewall of the tire and indicate the date of manufacture (See Tire Labeling on page 576). CONTINUED 537 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Tires Tire Maintenance In addition to proper inflation, correct wheel alignment helps to decrease tire wear. If you find a tire is worn unevenly, have your dealer check the wheel alignment. Have your dealer check the tires if you feel a consistent vibration while driving. A tire should always be rebalanced if it is removed from the wheel. When you have new tires installed, make sure they are balanced. This increases riding comfort and tire life. For best results, have the installer perform a dynamic balance. Improper wheel weights can damage your vehicle's aluminum wheels. Use only Acura wheel weights for balancing. 538 Tire Rotation Front Front (For Directional Tires and Wheels) (For Non-directional Tires and Wheels) To help increase tire life and distribute wear more evenly, rotate the tires according to the maintenance messages displayed on the multi-information display. Move the tires to the positions shown in the illustration each time they are rotated. If you purchase directional tires, rotate only front-to-back. Replacing Tires and Wheels Replace your tires with radial tires of the same size, load range, speed rating, and maximum cold tire pressure rating (as shown on the tire's sidewall). Mixing radial and bias-ply tires on your vehicle can reduce braking ability, traction, and steering accuracy. Using tires of a different size or construction can cause the ABS and vehicle stability assist system (VSA) to work inconsistently. The ABS works by comparing the speed of the wheels. When replacing tires, use the same size originally supplied with the vehicle. Tire size and construction can affect wheel speed and may cause the system to activate. When the tires are rotated, make sure the air pressures are checked. 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu It is best to replace all four tires at the same time. If that is not possible or necessary, replace the two front tires or two rear tires as a pair. Replacing just one tire can seriously affect your vehicle's handling. If you ever replace a wheel, make sure that the wheel's specifications match those of the original wheels. Also be sure you use only TPMS specific wheels. If you do not, the tire pressure monitoring system will not work. Replacement wheels are available at your dealer. Installing improper tires on your vehicle can affect handling and stability. This can cause a crash in which you can be seriously hurt or killed. Always use the size and type of tires recommended in this owner's manual.

Winter Driving Tires marked ‘‘M ＋ S’’ or ‘‘All Season’’ on the sidewall have an all- weather tread design suitable for most winter driving conditions. For the best performance in snowy or icy conditions, you should install snow tires or tire chains. They may be required by local laws under certain conditions. CONTINUED 539 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Tires Snow Tires If you mount snow tires on your vehicle, make sure they are radial tires of the same size and load range as the original tires. Mount snow tires on all four wheels. The traction provided by snow tires on dry roads may be lower than your original tires. Check with the tire dealer for maximum speed recommendations. Tire Chains Mount tire chains on your tires when required by driving conditions or local laws. Install them only on the front tires. Because your vehicle has limited tire clearance, Acura strongly recommends using the chains listed below. SCC Super Z-6＃ SC 435 540 When installing chains, follow the manufacturer's instructions and mount them as tightly as you can. Drive slowly with chains installed. If you hear them contacting the body or chassis, stop and investigate. Make sure the chains are installed tightly, and that they are not contacting the brake lines or suspension. Remove the chains as soon as you start driving on cleared roads. Using the wrong chains, or not properly installing chains, can damage the brake lines and cause a crash in which you can be seriously injured or killed. Follow all instructions in this owner's manual regarding the selection and use of tire chains. Traction devices that are the wrong size or improperly installed can damage your vehicle's brake lines, suspension, body, and wheels. Stop driving if they are hitting any part of the vehicle. Wheels Clean the wheels as you would the rest of the exterior. Wash them with the same solution, and rinse them thoroughly. Aluminum alloy wheels have a protective clear-coat that keeps the aluminum from corroding and tarnishing. Cleaning the wheels with harsh chemicals (including some commercial wheel cleaners) or a stiff brush can damage the clear-coat. To clean the wheels, use a mild detergent and a soft brush or sponge. 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu The sensor on the negative terminal monitors your vehicles battery condition. If there is a problem with the sensor, you will see a ‘‘CHECK BATTERY SENSOR’’ message on the multi- information display. Have the vehicle checked by your dealer. Check the terminals for corrosion (a white or yellowish powder). To remove it, cover the terminals with a solution of baking soda and water. It will bubble up and turn brown. When this stops, wash it off with plain water. Dry off the battery with a cloth or paper towel. Coat the terminals with grease to help prevent further corrosion. If additional battery maintenance is needed, see your dealer or a qualified technician. WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling. If you need to connect the battery to a charger, disconnect both cables to prevent damaging your vehicle's electrical system. Always disconnect the negative (－) cable first, and reconnect it last. Checking the Battery The battery gives off explosive hydrogen gas during normal operation. A spark or flame can cause the battery to explode with enough force to kill or seriously hurt you. Wear protective clothing and a face shield, or have a skilled technician do the battery maintenance. If the radio fuse is removed, the audio system will disable itself. The next time you turn on the radio you will see ‘‘ENTER CODE’’ in the frequency display. Use the preset buttons to enter the digit code (see page 305). 541 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Vehicle Storage If you need to park your vehicle for an extended period (more than 1 month), there are several things you should do to prepare it for storage. Proper preparation helps prevent deterioration and makes it easier to get your vehicle back on the road. If possible, store your vehicle indoors. ● Fill the fuel tank. ● Wash and dry the exterior completely. ● Clean the interior. Make sure the carpeting, floor mats, etc., are completely dry. ● Leave the parking brake off. Put the transmission in Park. 542 ● Cover the vehicle with a ‘‘breathable’’ cover, one made from a porous material such as cotton. Non-porous materials, such as plastic sheeting, trap moisture, which can damage the paint. ● If possible, periodically run the engine until it reaches full operating temperature (the cooling fans cycle on and off twice). Preferably, do this once a month. ● Block the rear wheels. ● If the vehicle is to be stored for a longer period, it should be supported on jackstands so the tires are off the ground. ● Leave one window open slightly (if the vehicle is being stored indoors). ● Disconnect the battery. ● Support the front and rear wiper blade arms with a folded towel or rag so they do not touch the windshield. ● To minimize sticking, apply a silicone spray lubricant to all door and tailgate seals. Also, apply a vehicle body wax to the painted surfaces that mate with the door and tailgate seals. 2011 MDX10/06/29 11:59:04 11 ACURA MDX MMC North America Owner's M 50 31STX640 enu Taking Care of the Unexpected This section covers the more common problems that motorists experience with their vehicles.
