Important Maintenance Precautions If you have the required service done but do not reset the display, or reset the display without doing the service, the system will not show the proper maintenance intervals. This can lead to serious mechanical problems because you will no longer have an accurate record of when maintenance is needed.

Your authorized Acura 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.

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.

Adding Engine Oil

ENGINE OIL FILL CAP

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.

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 any. Clean up any spills immediately. Spilled oil could damage components in the engine compartment.

336

Required Engine Oil Oil is a major contributor to your engine’s performance and longevity. Your vehicle is equipped with a high- performance turbocharged engine that requires the use of synthetic motor oil. Always use Mobil 1
5W-30 or an equivalent oil that meets the Acura HTO-06 standard. Not all synthetic oils will meet this standard. Only use oils that display the HTO-06 standard on the label.

Failure to use Mobil 1 or an equivalent oil that meets the HTO-06
standard can lead to a reduction in engine performance or durability, and can cause engine damage not covered by your warranty.

RESERVE TANK

MAX

MIN

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.

340

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.

Headlight Aiming The headlights were properly aimed when your vehicle was new. If you regularly carry heavy items in the cargo area or pull a trailer, readjustment may be required. Adjustments should be done by your dealer or another qualified technician.

Replacing a High Beam Headlight Bulb Your vehicle has halogen headlight bulbs. When replacing a bulb, handle it by its base, and protect the glass from contact with your skin or hard objects. If you touch the glass, clean it with denatured alcohol and a clean cloth.

Low Beam Headlight Bulb Replacement The low beam headlight bulbs are a type of high voltage discharge tube. High voltage can remain in the circuit even with the light switch off and the key removed. Because of this, you should not attempt to examine or change a low beam headlight bulb yourself. If a low beam headlight bulb fails, take the vehicle to your dealer to have it replaced.

Halogen headlight bulbs get very hot when lit. Oil, perspiration, or a scratch on the glass can cause the bulb to overheat and shatter.

Cleaning the Seat Belts, Floor Mats

Cleaning the Seat Belts

Floor Mats

LOOP

If you use a non-Acura floor mat, make sure it fits properly and that it can be used with the floor mat anchors. Do not put additional floor mats on top of the anchored mats.

If your seat belts get dirty, use a soft brush with a mixture of mild soap and warm water to clean them. Do not use bleach, dye, or cleaning solvents. Let the belts air-dry before you use the vehicle. Dirt build-up in the loops of the seat belt anchors can cause the belts to retract slowly. Wipe the insides of the loops with a clean cloth dampened in mild soap and warm water or isopropyl alcohol.

354

FLOOR MAT ANCHORS

The driver’s and front passenger’s floor mats that came with your vehicle hook over the floor mat anchors. To lock each anchor, turn the knob clockwise. This keeps the floor mats from sliding forward (possibly interfering with the pedals), or backwards (making the front passenger’s weight sensors ineffective). If you remove a floor mat, make sure to re-anchor it when you put it back in your vehicle.

Audio Antenna

Intercooler

ANTENNA

INTERCOOLER

Your vehicle is equipped with a intercooler on the engine to cool the air flow from a turbo charger into the engine. The intercooler fins bend easily. Do not push them with your finger.

Your vehicle is equipped with an antenna at the rear of the roof . Bef ore using a ‘‘drive-through’’ car wash, remove the antenna by unscrewing it by hand. This prevents the antenna f rom being damaged by the car wash brushes.

Do not spray water (f rom such sources as garden hoses, high pressure sprayers) into the engine compartment. It may cause serious damage to your vehicle, and could also damage the intercooler f ins.

Dust and Pollen Filter This filter removes the dust and pollen that is brought in from the outside through the climate control system.

Have your dealer replace the filter when this service is indicated by a maintenance message on the multi- information display. It should be replaced every 15,000 miles (24,000
km) if you drive primarily in urban areas that have high concentrations of soot in the air, or if the flow from the climate control system becomes less than usual.

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.

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.

360

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) will warn you when a tire pressure is low. See page for information on the TPMS.

307

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.

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.

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.

Tires

Recommended Tire Pressures The following charts show the recommended cold tire pressures for most normal driving conditions.

Tire Inspection Every time you check inflation, you should also examine the tires for damage, foreign objects, and wear.

Tire Size

P235/55R18 99V

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 )

For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver’s doorjamb.

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.

For additional information about your tires, see page

398

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.

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.

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.

Tires

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.

362

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

400

).

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.

Tires

Tire Rotation Front

Front

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).

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.

(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.

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 and VSA system work 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 ABS or VSA system to activate.

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.

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.

2009 RDX ０８／０４／１１　１８：５１：３４　３１ＳＴＫ６２０　０３７０　

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, made by Security Chain Company (SCC).

Cable type: Shur Grip Z SZ343

When installing cables, follow the manufacturer’s instructions, and mount them as tight as you can. Make sure they are not contacting the brake lines or suspension. Drive slowly with them installed. If you hear them coming into contact with the body or chassis, stop and investigate. Remove them as soon as you begin driving on cleared roads.

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.

Tires

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.

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.

368

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.
