These recommended oil grades can be identified by looking for either or both of the following marks displayed on the oil container.


ILSAC Certification Mark (Starburst Mark) In choosing an oil, you want the proper quality and viscosity, as well as one that will add to fuel economy. The following table lists the recommended viscosities and applicable temperatures. When adding oil, different brands may be used together as long as they are the same API classification and SAE viscosity as those recommended by SUBARU.

& Synthetic oil You can use synthetic engine oil that meets the same requirements given for conventional engine oil. When using synthetic oil, you must use oil of the same classification, viscosity and grade shown in this Owner’s Manual, and must follow the oil and filter changing intervals shown in the maintenance schedule.


Cooling system


WARNING


Never attempt to remove the radia- tor cap until the engine has been shut off and has cooled down completely. Since the coolant is under pressure, you may suffer serious burns from a spray of boil- ing hot coolant when the cap is removed.


CAUTION


. Vehicles are filled at the factory with SUBARU Super Coolant that does not require the first change for 11 years/137,500 miles (11
years/220,000 km). This coolant should not be mixed with any other brand or type of coolant during this period. Mixing with a different coolant will reduce the life of the coolant. Should it be necessary to top up the coolant f o r a n y r e a s o n , u s e o n l y SUBARU Super Coolant. If the SUBARU Super Coolant is diluted with another brand or type, the maintenance interval is

shortened to that of the mixing coolant.


. Do not splash the engine coolant over painted parts. The alcohol contained in the engine coolant may damage the paint surface.


& Cooling fan, hose and con-


nections


Your vehicle employs an electric cooling fan which is thermostatically controlled to operate when the engine coolant reaches a specific temperature. If the radiator cooling fan does not operate even when the engine coolant tempera- ture gauge exceeds the normal operating range, the cooling fan circuit may be defective. Check the fuse and replace it if necessary. If the fuse is not blown, have the cooling system checked by your SUBARU dealer.


If frequent addition of coolant is neces- sary, there may be a leak in the engine cooling system. It is recommended that the cooling system and connections be checked for leaks, damage, or looseness.

Tires and wheels & Types of tires You should be familiar with type of tires present on your vehicle. ! All season tires All season tires are designed to provide an adequate measure of traction, handling and braking performance in year-round driving including snowy and icy road conditions. However all season tires do not offer as much traction performance as winter (snow) tires in heavy or loose snow or on icy roads. All season tires are identified by “ALL SEASON” and/or “M+S” (Mud & Snow) on the tire sidewall. ! Summer tires Summer tires are high-speed capability tires best suited for highway driving under dry conditions. Summer tires are inadequate for driving on slippery roads such as on snow- covered or icy roads. If you drive your vehicle on snow-covered or icy roads, we strongly recommend the use of winter (snow) tires. When installing winter tires, be sure to replace all four tires.


! Winter (snow) tires Winter tires are best suited for driving on snow-covered and icy roads. However winter tires do not perform as well as summer tires and all season tires on roads other than snow-covered and icy roads.


& Tire pressure monitoring


system (TPMS) (if equipped) The tire pressure monitoring system pro- vides the driver with a warning message by sending a signal from a sensor that is installed in each wheel when tire pressure is severely low. The tire pressure monitor- ing system will activate only when the vehicle is driven. Also, this system may not react immediately to a sudden drop in tire pressure (for example, a blow-out caused by running over a sharp object).


If you adjust the tire pressures in a warm garage and will then drive the vehicle in cold outside air, the resulting drop in tire pressures may cause the low tire pressure warning light to illuminate. To avoid this problem when adjusting the tire pressures in a warm garage, inflate the tires to pressures higher than those shown on the tire placard. Specifically, inflate them by an extra 1 psi (6.9 kPa, 0.07 kgf/cm2) for every difference of 108F (5.68C) between the temperature in the garage and the


Maintenance and service 11-33


temperature outside. By way of example, the following table shows the required tire pressures that correspond to various out- side temperatures when the temperature in the garage is 608F (15.68C). Example: Ti r e s i z e : P 2 0 5 / 5 5 R 1 6 8 9 V a n d P205/50R17 88V Standard tire pressures: Front: 33 psi (230 kPa, 2.3 kgf/cm2) Rear: 32 psi (220 kPa, 2.2 kgf/cm2) Garage temperature: 608F (15.68C)

If the low tire pressure warning light illuminates when you drive the vehicle in cold outside air after adjusting the tire pressures in a warm garage, re-adjust the tire pressures using the method described above. Then, increase the vehicle speed to at least 20 mph (32 km/h) and check to see that the low tire pressure warning light turns off a few minutes later. If the low tire pressure warning light does not turn off,

the tire pressure monitoring system may not be functioning normally. In this event, go to a SUBARU dealer to have the system inspected as soon as possible.


While the vehicle is driven, friction be- tween tires and the road surface causes the tires to warm up. After illumination of the low tire pressure warning light, any increase in the tire pressures caused by an increase in the outside air temperature or by an increase in the temperature in the tires can cause the low tire pressure warning light to turn off.


System resetting is necessary when the wheels are changed (for example, a switch to snow tires) and new TPMS valves are installed on the newly fitted wheels. Have this work performed by a SUBARU dealer following wheel replace- ment.


It may not be possible to install TPMS valves on certain wheels that are on the market. Therefore, if you change the wheels (for example, a switch to snow tires), use wheels that have the same part number as the standard-equipment wheels. Without four operational TPMS valve/sensors on the wheels, the TPMS will not fully function and the warning light on the combination meter will illuminate steadily after blinking for approximately


one minute.


When a tire is replaced, adjustments are necessary to ensure continued normal operation of the tire pressure monitoring system. As with wheel replacement, there- fore, you should have the work performed by a SUBARU dealer.


WARNING


If the low tire pressure warning light does not illuminate briefly after the ignition switch is turned ON or the light illuminates steadily after blink- ing for approximately one minute, you should have your Tire Pressure Monitoring System checked at a SUBARU dealer as soon as possi- ble. If this light illuminates while driving, never brake suddenly and keep driving straight ahead while gradu- ally reducing speed. Then slowly pull off the road to a safe place. Otherwise an accident involving serious vehicle damage and serious personal injury could occur. If illuminates while driving after adjusting the tire pres- sure, a tire may have significant damage and a fast leak that causes the tire to lose air rapidly. If you have

a flat tire, replace it with a spare tire as soon as possible. When a spare tire is mounted or a wheel rim is replaced without the original pressure sensor/transmitter being transferred, the low tire pres- sure warning light will illuminate steadily after blinking for approxi- mately one minute. This indicates the TPMS is unable to monitor all four road wheels. Contact your SUBARU dealer as soon as possible for tire and sensor replacement and/ or system resetting. the light illuminates steadily after blinking for approximately one minute, promptly contact a SUBARU dealer to have the system inspected.


If


& Tire inspection Check on a daily basis that the tires are free from serious damage, nails, and stones. At the same time, check the tires for abnormal wear. Contact your SUBARU dealer ately if you find any problem. NOTE . When the wheels and tires strike curbs or are subjected to harsh treat- ment as when the vehicle is driven on a


immedi-


rough surface, they can suffer damage that cannot be seen with the naked eye. This type of damage does not become evident until time has passed. Try not to drive over curbs, potholes or on other rough surfaces. If doing so is unavoidable, keep the vehicle’s speed down to a walking pace or less, and approach the curbs as squarely as possible. Also, make sure the tires are not pressed against the curb when you park the vehicle. . If you feel unusual vibration while driving or find it difficult to steer the vehicle in a straight line, one of the tires and/or wheels may be damaged. Drive slowly to the nearest authorized SUBARU dealer and have the vehicle inspected.


& Tire pressures and wear Maintaining the correct tire pressures helps to maximize the tires’ service lives and is essential for good running perfor- mance. Check and, if necessary, adjust the pressure of each tire (including the spare) at least once a month (for example, during a fuel stop) and before any long journey.


Check the tire pressures when the tires are cold. Use a pressure gauge to adjust the tire pressures to the values shown on the tire placard. The tire placard is located on the door pillar on the driver’s side.


Driving even a short distance warms up the tires and increases the tire pressures. Also, the tire pressures are affected by the outside temperature. It is best to check tire pressure outdoors before driving the vehicle.


When a tire becomes warm, the air inside it expands, causing the tire pressure to increase. Be careful not to mistakenly release air from a warm tire to reduce its pressure.


Maintenance and service 11-35


NOTE . The air pressure in a tire increases by approximately 4.3 psi (30 kPa, 0.3
kgf/cm2) when the tire becomes warm. . The tires are considered cold when the vehicle has been parked for at least three hours or has been driven less than one mile (1.6 km).


WARNING


Do not let air out of warm tires to adjust pressure. Doing so will result in low tire pressure.


Incorrect tire pressures detract from con- trollability and ride comfort, and they cause the tires to wear abnormally.

& Wheel balance Each wheel was correctly balanced when your vehicle was new, but the wheels will become unbalanced as the tires become worn during use. Wheel imbalance causes the steering wheel to vibrate slightly at certain vehicle speeds and detracts from the vehicle’s straight-line stability. It can also cause steering and suspension sys- tem problems and abnormal tire wear. If you suspect the wheels are not correctly balanced, have them checked and adjusted by your SUBARU dealer. Also have them adjusted after tire repairs and after tire rotation. NOTE Loss of correct wheel alignment* causes the tires to wear on one side and reduces the vehicle’s running stability. Contact your SUBARU dealer if you notice abnormal tire wear. *: The suspension system is designed to hold each wheel at a certain alignment (relative to the other wheels and to the road) for optimum straight-line stability and cornering perfor- mance.

Tread wear indicator


Each tire incorporates a tread wear indicator, which becomes visible when the depth of the tread grooves decreases to 0.063 in (1.6 mm). A tire must be replaced when the tread wear indicator appears as a solid band across the tread.


WARNING


When a tire’s tread wear indicator becomes visible, the tire is worn beyond the acceptable limit and must be replaced immediately. With a tire in this condition, driving at high speeds in wet weather can

After driving approximately 600 miles (1,000 km), check the wheel nuts again and retighten any nut that has become loose.


& Tire replacement The wheels and tires are important and integral parts of your vehicle’s design; they cannot be changed arbitrarily. The tires fitted as standard equipment are optimally matched to the characteristics of the vehicle and were selected to give the best possible combination of running performance, ride comfort, and service life. It is essential for every tire to have a size and construction matching those shown on the tire placard and to have a speed symbol and load index matching those shown on the tire placard.


Using tires of a non-specified size detracts from controllability, ride comfort, braking performance, speedometer accuracy and odometer accuracy. It also creates incor- rect body-to-tire clearances and inappro- priately changes the vehicle’s ground clearance.


All four tires must be the same in terms of manufacturer, brand (tread pattern), con- struction, and size. You are advised to replace the tires with new ones that are identical to those fitted as standard equip- ment.


For safe vehicle operation, SUBARU recommends replacing all tires at the same time.

Maintenance and service 11-39


WARNING


. All four tires must be the same in terms of manufacturer, brand (tread pattern), construction, de- gree of wear, speed symbol, load index and size. Mixing tires of different types, sizes or degrees of wear can result in damage to vehicle’s powertrain. Use of dif- ferent types or sizes of tires can also dangerously reduce con- trollability and braking perfor- mance and can lead to an acci- dent.


. Use only radial tires. Do not use radial tires together with belted bias tires and/or bias-ply tires. Doing so can dangerously re- duce controllability, resulting in an accident.


WARNING


Aluminum wheels


Use only those wheels that are specified for your vehicle. Wheels not meeting specifications could interfere with brake caliper opera- tion and may cause the tires to rub against the wheel well housing dur- ing turns. The resulting loss of vehicle control could lead to an accident.


NOTE When any of the wheels are removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driv- ing approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque.


Aluminum wheels can be scratched and damaged easily. Handle them carefully to maintain their appearance, performance, and safety. . When any of the wheels are removed and replaced for tire rotation or to change a flat tire, always check the tightness of the wheel nuts after driving approximately 600 miles (1,000 km). If any nut is loose, tighten it to the specified torque. . Never apply oil to the threaded parts, wheel nuts, or the wheel. . Never let the wheel rub against sharp protrusions or curbs. . When wheel nuts, balance weights, or the center cap is replaced, be sure to replace them with genuine SUBARU parts designed for aluminum wheels.

Otherwise, if the concentration of the fluid remaining in the piping is too low for the outside temperature, it may freeze and block the nozzles.


CAUTION


Adjust the washer fluid concentra- tion appropriately for the outside temperature. If the concentration is inappropriate, sprayed washer fluid may freeze on the windshield and obstruct your view, and the fluid may freeze in the reservoir tank.


Replacement of wiper blades


Grease, wax, insects, or other material on the windshield or the wiper blade results in jerky wiper operation and streaking on the glass. If you cannot remove the streaks after operating the windshield washer or if the wiper operation is jerky, clean the outer surface of the windshield (or rear window) and the wiper blades using a sponge or soft cloth with a neutral detergent or mild-abrasive cleaner. After cleaning, rinse the windshield and wiper blades with clean water. The windshield is clean if beads do not form when you rinse the windshield with water.


CAUTION


Do not clean the wiper blades with gasoline or a solvent, such as paint thinner or benzine. This will cause deterioration of the wiper blades.


If you cannot eliminate the streaking even after following this method, replace the wiper blades using the following proce- dures:
