Maintenance Sub Items

MAINTENANCE SUB ITEMS REFERENCE

Number	Maintenance Sub Items
1	Rotate tires, and check tire inflation and condition. Follow the pattern shown in the Owner's Manual.
2	Replace air cleaner element (see AIR CLEANER ELEMENT INSPECTION/REPLACEMENT ). If the vehicle is regularly driven in dusty conditions, replace every 15,000 miles (24,000 km).
	Replace dust and pollen filter (see DUST AND POLLEN FILTER REPLACEMENT ). If the vehicle is driven in urban areas that have high concentrations of dust, pollen, or soot in the air, replace every 15,000 miles (24,000 km). Replace the filter whenever airflow from the heating and air conditioning system is less than normal.
	Inspect drive belt (see DRIVE BELT INSPECTION ). Look for cracks and damage, and inspect auto tensioner; no adjustment is needed.
3	Replace automatic transmission fluid (see ATF REPLACEMENT ) and transfer fluid (see TRANSFER ASSEMBLY FLUID REPLACEMENT ). Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission and transfer temperatures. This requires transmission and transfer fluid changes more frequently than recommended by the maintenance minder. If the vehicle is regularly driven in these conditions, replace the transmission and transfer fluid at 60,000 miles (96,000 km), then every 30,000 miles (48,000 km). Automatic transmission fluid capacity: 2.7 L (2.9 US qt), use Acura Automatic Transmission Fluid (ATF-Z1). Transfer fluid capacity: 0.43 L (0.45 US qt), use hypoid gear oil GL4 or GL5.
4	Replace spark plugs (see SPARK PLUG INSPECTION ). Use IZFR6K11 (NGK) or SKJ20DR-M11 (DENSO).
	Replace timing belt (see TIMING BELT REMOVAL ). If the vehicle is regularly driven in very high temperatures (over 110°F, 43°C, or in very low temperatures (under -20°F, -29°C), replace every 60,000 miles (USA)/ 100,000 km (Canada) and inspect water pump (see WATER PUMP INSPECTION ).
	Inspect the valve clearance (cold) (see VALVE CLEARANCE ADJUSTMENT ). Otherwise adjust only if noisy. Intake: 0.20-0.24 mm (0.008-0.009 in.), Exhaust: 0.28-0.32 mm (0.011-0.013 in.)
5	Replace engine coolant (see COOLANT REPLACEMENT ). Capacity (including the reservoir): 6.0 L (1.59 US gal), use Acura Long Life Antifreeze/Coolant Type 2.
6	Replace rear differential fluid (see REAR DIFFERENTIAL FLUID INSPECTION AND REPLACEMENT ). Driving in mountainous areas at very low vehicle speeds or trailer towing results; in higher level of mechanical (shear) stress to fluid. This requires differential fluid changes more frequently than recommended by the maintenance minder. If the vehicle is regularly driven in these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km). Capacity: Clutch chambers 2.7 L (2.9 US qt), Hypoid gear chamber 0.73 L (0.77 U 3 qt), use Acura Automatic Transmission Fluid (ATF-Z1).

SUPPLEMENTAL RESTRAINT SYSTEM (SRS) (If engine electrical maintenance is required)

The Acura RL SRS includes a driver's airbag in the steering wheel hub, a passenger's airbag in the dashboard above the glove box, seat belt tensioners in the front seat belt retractors, side curtain airbags in the sides of the roof, and side airbags in the front seat-backs. Information necessary to safely service the SRS is included in this Service Manual. Items marked with an asterisk (*) on the contents page include or are located near SRS components. Servicing, disassembling, or replacing these items requires special precautions and tools, and should be done by an authorized Acura dealer.

To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal or side collision, all SRS service work should be done by an authorized Acura dealer.
Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury caused by unintentional deployment of the airbags and/or side airbags.
Do not bump or impact the SRS unit, front impact sensors, or side impact sensors when the ignition switch is ON (II), or for at least 3 minutes after the ignition switch is turned OFF; otherwise, the system may fail in a collision, or the airbags may deploy.
SRS electrical connectors are identified by yellow color coding. Related components are located in the steering column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box, in the front seats, in the roof side, and around the floor. Do not use electrical test equipment on these circuits.
