ENGINE OIL FILL CAP


Unscrew and remove the engine oil fill cap on top of the valve cover. Pour in the oil slowly and carefully so you do not spill. Clean up any spills immediately. Spilled oil could damage components in the engine compartment. Reinstall the engine oil fill cap, and tighten it securely. Wait a few minutes, and recheck the oil level on the engine oil dipstick. Do not fill above the upper mark; you could damage the engine.


Recommended Engine Oil Oil is a major contributor to your engine’s performance and longevity. Always use a premium-grade 5W-20
detergent oil displaying the API Certification Seal. This seal indicates the oil is energy conserving, and that it meets the American Petroleum Institute’s latest requirements. It is highly recommended that you use Honda motor oil in your vehicle. Make sure the API Certification Seal says ‘‘For Gasoline Engines.’’

If the coolant level in the reserve tank is at or below the MIN line, add coolant to bring it up to the MAX line. Inspect the cooling system for leaks.


396


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.


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 water.


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.

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.


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 more information.


351


for


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


Tires


immediately with a tire gauge.


Use 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/cm ) per month. Remember to check the spare tire at the same time.


CONTINUED


415


2008 MDX 07/07/09 10:18:42 31STX610 0421 


Tires


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/cm ) 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.


Recommended Tire Pressures The following chart shows the recommended cold tire pressures for most normal and high-speed driving conditions.


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.


Tire Size


P255/55R18 104H


Cold Tire Pressure for Normal Driving


Front/Rear: 32 psi (220 kPa , 2.2 kgf/cm )


The compact spare tire pressure is: 60 psi (420 kPa , 4.2 kgf/cm )

416


2008 MDX 07/07/09 10:18:52 31STX610 0422 


Tires


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.


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. The last four digits of the TIN (tire identification number) are found on the sidewall of the tire and indicate Tire the date of manufacture (See Labeling


on page


456


).


417


2008 MDX 07/07/09 10:19:02 31STX610 0423 


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 f or balancing.


418


Tire Rotation


Front


Front


(For Non-directional Tires and Wheels)


(For 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.


2008 MDX 07/07/09 10:19:13 31STX610 0424 


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.

Tires


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.


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.

Because your vehicle has limited tire clearance, Acura strongly recommends using the chains listed below.


SCC Super Z-6 SZ 435



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.

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.


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.

TEST INDICATOR WINDOW


Check the condition of the battery monthly by looking at the test indicator window:


Green White

Black



Good condition Liquid level low, replace battery Charging necessary


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.


Battery posts,


WARNING: 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 ( − 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

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.


422


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.


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.

Taking Care of the Unexpected


This section covers the more common problems that motorists experience with their vehicles. It gives you information about how to safely evaluate the problem and what to do to correct it. If the problem has stranded you on the side of the road, you may be able to get going again. If not, you will also find instructions on getting your vehicle towed.

Compact Spare Tire


Use the compact spare tire as a temporary replacement only. Get your regular tire repaired or replaced, and put it back on your vehicle as soon as you can.


Check the inflation pressure of the compact spare tire every time you check the other tires. It should be inflated to: 60 psi (420 kPa , 4.2 kgf/cm )


Follow these precautions:


Never exceed 50 mph (80 km/h).


This tire gives a harsher ride and less traction on some road surfaces. Use greater caution while driving.


424


Do not mount snow chains on a compact spare.


Do not use your compact spare tire on another vehicle unless it is the same make and model.


INDICATOR LOCATION MARK


After the flat tire is replaced with the spare tire, the low tire pressure/TPMS indicator stays on. After several miles (kilometers) driving with the spare, this indicator begins to flash, then stays on again. You will also see a ‘‘CHECK TPMS SYSTEM’’ message on the multi-information display (see page


354


).


TREAD WEAR INDICATOR BAR


Replace the tire when you can see the tread wear indicator bars. The replacement should be the same size and design tire, mounted on the same wheel. The spare tire is not designed to be mounted on a regular wheel, and the spare wheel is not designed for mounting a regular tire.


2008 MDX 07/07/09 10:19:57 31STX610 0430 


If you have a flat tire while driving, stop in a safe place to change it. Drive slowly along the shoulder until you get to an exit or an area to stop that is far away from the traffic lanes.
