Procedure

1. 1

   Engine oil and filter change
   Position drain pan under engine oil drain plug located on passenger side of oil pan. Remove drain plug using 14mm socket and allow oil to drain completely (approximately 10 minutes). Inspect drain plug threads and oil pan threads for damage. Install new crush washer on drain plug and reinstall. Move drain pan under oil filter (located on front of engine, driver side). Remove old filter using oil filter wrench, ensuring old gasket comes off with filter. Lubricate new filter gasket with fresh oil, install new filter hand-tight plus 3/4 turn. Refill engine with 4.4 quarts of 0W-20 oil through filler cap on valve cover. Start engine and verify no leaks. Shut off and wait 5 minutes, then check level and add remaining oil to reach full mark on dipstick.
2. 2

   Engine air filter replacement
   Open hood and locate air filter housing on driver side of engine bay. Release four clips securing air box cover. Lift cover and remove old air filter element. Inspect air box for debris or contamination and clean if necessary. Install new air filter ensuring proper seating in housing. Reinstall cover and secure all four clips firmly until they click.
3. 3

   Cabin air filter replacement
   Open glove box and remove contents. Press inward on both sides of glove box to release stops and lower fully. Locate cabin air filter cover on right side of HVAC housing. Press tabs to release cover and remove. Slide old cabin air filter out, noting airflow direction arrows. Vacuum debris from filter housing if present. Install new cabin air filter matching airflow direction arrows. Reinstall cover until tabs click into place. Return glove box to normal position.
4. 4

   Spark plug replacement
   Remove engine cover by pulling upward (secured by rubber grommets). Locate four ignition coils on top of valve cover. Disconnect electrical connector from each coil by pressing release tab. Remove single 10mm bolt securing each coil. Pull coils straight up and out of spark plug tubes. Use compressed air to clean debris from spark plug tubes. Using 14mm spark plug socket with extension, remove old spark plugs (turn counterclockwise). Inspect old plugs for abnormal wear patterns. Verify new plug gap is 0.039-0.043 inches (1.0-1.1mm) - do not regap iridium plugs unless necessary. Apply small amount of anti-seize to plug threads (avoid electrode area). Install new plugs hand-tight, then torque to 18 Nm (13 lb-ft) using torque wrench. Reinstall ignition coils ensuring they seat fully into spark plug tubes. Reinstall coil bolts and reconnect electrical connectors. Reinstall engine cover.
5. 5

   Automatic transmission fluid drain and fill
   Locate transmission drain plug on bottom of transmission pan (accessible from underneath vehicle). Position drain pan underneath. Remove drain plug using 10mm hex socket and allow fluid to drain completely (approximately 4 quarts will drain). Inspect drain plug magnet for metal debris (small amount of fine gray residue is normal). Remove old gasket from drain plug and install new gasket. Reinstall drain plug and torque to 29 Nm (21 lb-ft). Locate transmission fill plug on passenger side of transmission (accessible from wheel well area with wheel removed or turned fully). Remove fill plug using 24mm socket. Using fluid transfer pump, add 4.0 quarts of Toyota WS ATF through fill hole until fluid begins to seep out. Reinstall fill plug while vehicle is level. Start engine, shift through all gears pausing 3 seconds in each position, return to Park. Check fluid level at operating temperature using fill plug (small weep is correct level).
6. 6

   Coolant system inspection and top-off
   With engine completely cold, inspect coolant overflow reservoir level (marked on passenger side tank near firewall). Level should be between MIN and MAX marks. Remove reservoir cap and verify coolant is pink in color and free of contamination. Top off with Toyota Super Long Life Coolant if below MIN mark. Remove radiator cap (after confirming engine is cold) and verify coolant is at neck of radiator. Top off if necessary. Inspect all coolant hoses for cracks, swelling, or leaks. Check radiator and water pump for leaks. Reinstall both caps securely. At 90K service, full coolant flush is recommended but not mandatory - if performing flush, use Toyota-approved exchange procedure to prevent air pockets.
7. 7

   Brake fluid flush
   Locate brake fluid reservoir under master cylinder cover in engine bay. Remove cap and verify fluid is DOT 3 and not contaminated (dark brown indicates moisture contamination). Using brake fluid bleeding kit or assistant, begin at right rear wheel. Remove bleeder screw cap, attach clear tube to bleeder screw with other end in catch bottle. Have assistant pump brake pedal 3 times and hold. Open bleeder screw 1/2 turn until fluid flows, then close before pedal reaches floor. Repeat until fluid runs clear with no bubbles. Monitor reservoir level constantly and refill to prevent air entry. Repeat process at left rear, right front, then left front wheels. After bleeding all wheels, verify firm brake pedal and top reservoir to MAX line. Properly dispose of old brake fluid according to local regulations.
8. 8

   Multi-point inspection
   With vehicle on jack stands, perform comprehensive inspection: Check all brake pad thickness at all four wheels (minimum 3mm remaining). Inspect brake rotors for scoring, heat cracks, or excessive wear. Measure tire tread depth at multiple points (minimum 3/32 inch or 2.4mm). Inspect tires for uneven wear, cracks, or bulges. Check all suspension components for wear, damage, or leaks (struts, control arms, ball joints, tie rods). Inspect CV axle boots for tears or grease leaks. Check exhaust system for rust, damage, or loose hangers. Verify battery terminals are clean and tight. Inspect serpentine belt for cracks, glazing, or fraying (replace if worn). Check all underbody for fluid leaks, damage, or rust. Test all exterior lights for proper operation. Verify windshield wipers are in good condition.
9. 9

   Lower vehicle and wheel torque verification
   Carefully lower vehicle from jack stands using floor jack. Remove jack stands and lower vehicle completely to ground. Using torque wrench with 21mm socket, verify all wheel lug nuts are torqued in star pattern (cross pattern for even seating). Start with one lug nut, then move to opposite nut, continuing in star pattern until all nuts on wheel are torqued. Repeat for all four wheels. Double-check that no tools or parts are left under vehicle or in engine bay.
10. 10

    Final verification and maintenance reset
    Start engine and verify no warning lights are illuminated. Check for any fluid leaks underneath vehicle. Verify engine runs smoothly with no misfires or unusual noises. Test drive vehicle for 5-10 minutes, verifying smooth transmission shifts and proper brake operation. After test drive, recheck all fluid levels and verify no leaks. Reset maintenance reminder light using scan tool or manual procedure: Turn ignition to ON (do not start engine), set odometer to trip A, turn ignition OFF, press and hold trip reset button, turn ignition to ON while holding button until maintenance light begins to flash, release button and press again until reset is complete. Document all service performed and findings from inspection.

Reassembly

1. Verify all drain plugs and fill plugs are properly installed and torqued
2. Confirm all clips, covers, and shields are reinstalled in engine bay and underneath vehicle
3. Double-check that all electrical connectors are properly secured
4. Ensure engine cover is properly seated on all mounting grommets
5. Verify glove box operates normally and cabin air filter cover is secure

Verification

• All fluid levels should be at proper marks when checked cold (engine oil) or at operating temperature (transmission)
• Engine should idle smoothly with no misfire or rough running after spark plug replacement
• No fluid leaks should be present after 10-minute test drive and cool-down period
• Brake pedal should be firm with no sponginess after brake fluid flush
• All warning lights should be off and maintenance reminder should be reset
• Document any wear items that will need attention before next service interval
