Maintenance Sub Items
If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel- powered vehicles, replace every 15,000 miles (24,000 km).
Inspect drive belt Replace transmission and transfer fluid
Driving in mountainous terrain at very low vehicle speeds, towing a trailer, or driving when fully loaded results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the transmission and transfer fluid changed every 30,000 miles (48,000 km).
Replace spark plugs Replace timing belt and inspect water pump
If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under-20°F, -29°C), or towing a trailer, replace every 60,000 mile (U.S.)/100,000 km (Canada)
Inspect valve clearance Replace engine coolant Replace VTM-4 rear differential fluid
Driving in mountainous terrain at very low vehicle speeds, towing a trailer, or driving when fully loaded causes more mechanical (shear) stress and fluid deterioration. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Adding Engine Oil
ENGINE OIL FILL CAP
Unscrew and remove the engine oil fill cap on 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. 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.
Honda Motor Oil is the preferred 5W-20 lubricant for your vehicle. It is highly recommended that you use Honda Motor Oil in your vehicle for optimum engine protection. Make sure the API Certification Seal says ‘‘For Gasoline Engines.’’
The oil viscosity or weight is provided on the container’s label. 5W-20 oil is formulated for year- round protection of your vehicle to improve cold weather starting and fuel economy.

Adding Engine Oil, Changing the Engine Oil and Filter
Synthetic Oil You may use a synthetic motor oil if it meets the same requirements given for a conventional motor oil: it displays the API certification seal, and it is the proper weight. You must follow the oil and filter change intervals shown on the information display.
Engine Oil Additives Your vehicle does not require any oil additives. Additives may adversely affect the engine or transmission performance and durability.
Changing the Engine Oil and Filter Always change the oil and filter according to the maintenance messages shown on the odometer and trip meter display. The oil and filter collect contaminants that can damage your engine if they are not removed regularly.
Changing the oil and filter requires special tools and access from underneath the vehicle. The vehicle should be raised on a service station- type hydraulic lift for this service. Unless you have the knowledge and proper equipment, you should have this maintenance done by a skilled mechanic.

RESERVE TANK 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.
Engine Coolant
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.

Cleaning the Seat Belts, Floor Mats
A non-Honda floor mat may not fit your vehicle properly. This could prevent the proper operation of the folding rear seats and the passenger’s seat weight sensors. We recommend using genuine Honda floor mats. 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.
The floor mats that came with your vehicle hook over the floor mat anchors. 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.

Wheels Clean the wheels as you would the rest of the exterior. Wash them with the same solution, and rinse them thoroughly.
Tires To safely operate your vehicle, your tires must be the proper type and size, in good condition with adequate tread, and correctly inflated.
Ifequipped 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.
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.
2008 Ridgeline 07/04/27 14:16:55 31SJC620 0272
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.
208
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 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 on page
268
Tires
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
Never use a puncture-repairing agent in a flat tire. If used, you will have to replace the tire pressure sensor. Have the flat tire repaired by your dealer as soon as possible.
Recommended Tire Pressures The following chart shows the recommended cold tire pressures for most normal and high-speed driving conditions.
Tire Size
Cold Tire Pressure
P245/65R17 105T
Compact Spare
T165/90R17 105M

For convenience, the recommended tire sizes and cold tire pressures are on a label on the driver’s doorjamb.
For additional information about your tires, see page
308
268
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.
2008 Ridgeline 07/04/27 14:17:23 31SJC620 0274
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
308
).
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.
On vehicles with aluminum wheels, improper wheel weights can damage your vehicle’s aluminum wheels. Use only Honda wheel weights f or balancing.

Tires
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.
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.
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.
Both the ABS and VSA 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.

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.

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.
Tire Chains Mount tire chains on your tires when required by driving conditions or local laws. Install them only on the front tires. Do not use chains on the rear tires.
Because your vehicle has limited tire clearance, we strongly recommend using this Quality Chain Corp. tire chain:
Premium Cobra Cable Chain # adjusters
1046P with accessory
*
This tire chain is available at many auto supply stores. To find a local store that carries the chain, call Quality Chain Corp at 1-800-843-8824. To order the tire chain online, go to , and enter your www.chainquest.com vehicle information. When you install the chains, follow the manufacturer’s instructions, and mount them as tightly as you can. Drive slowly with the chains installed.
*
Rubber chain adjusters, or tensioners, must be used to prevent the chains from contacting the body or the chassis.

Checking the Battery
TEST INDICATOR WINDOW
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.
Check the condition of the battery monthly by looking at the test indicator window. The label on the battery explains the test indicator’s colors.
Tires, Checking the Battery
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.
If you ever hear the chains contacting the body or chassis, stop and investigate. If the chains have loosened, retighten them. Make sure they do not contact the brake lines or suspension.
Remove the chains as soon as you begin driving on cleared roads.

Checking the Battery
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 future 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.
) cable first, and
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.

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.
274
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 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, In-Bed Trunk lid, and tailgate seals. Also, apply a vehicle body wax to the painted surfaces that mate with the door, In-Bed Trunk lid and tailgate seals.

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.
276
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.
The tire pressure monitoring system (TPMS) indicator comes on and stays on after you replace the flat tire with the compact spare tire.
INDICATOR LOCATION MARK
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.

Changing a Flat Tire
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.
The vehicle can easily roll off the jack, seriously injuring anyone underneath.
Follow the directions for changing a tire exactly, and never get under the vehicle when it is supported only by the jack.
If you tow a trailer frequently, we recommend that you use a regular tire as a spare. You can store the regular size spare tire on the tire tray, but store the tool kit at the side of the In-Bed Trunk (see page ), and secure it.
